Arcesium Interview Questions :

1 .
What is the definition of a single point of failure in a distributed system?
Any component in a system that fails and renders the entire system worthless is known as a single point of failure. For instance, a computer that uses RAID storage can keep running even if one of its discs fails. We also have websites that replicate application servers on a wider scale. They, too, maybe vulnerable to SPOFS, as one server may go down with all data intact while the rest of the system remains operational.
2 .
What exactly is a Bootstrap Program in terms of operating systems?
A Bootstrap Program is typically a program that initialises the operating system during the startup of a computer system, in other words, the first program that runs when a computer system starts up. Booting is a method or application for loading the operating system. Overall, the bootstrap program is completely responsible for the operating system's performance and functionality. It is totally stored in boot blocks at a specific spot on the disc. It also locates and loads the kernel into the main memory before starting the program. The Bootstrap Program, as shown in the figure below, lies in the Read-Only Memory (ROM) of our computers and is responsible for reading the Operating Systems and loading them into the RAM (Random Access Memory) of our computers. After then, the operating systems can start other computer devices such as graphics cards, keyboards, and mice.
3 .
Define a 'Single Point of Failure' in a distributed system.
When SPOF or a single point of failure occurs in an IT environment, it entirely stops the system's operation. In other words, SPOF is a single fault that can potentially stop the entire operation of an IT environment.

Know that SPOF occurs in poorly-implemented IT environments. And it is generally classified into three types: software failure, hardware failure, and database corruption.

We can control SPOFs with the help of redundant systems and adequate backup arrangements. It means that we can use backup power, load balancers, and robust security infrastructure to control SPOFs.
4 .
Mention the limitations of OOP.
Below are the limitations of OOP.

* Programs usually go lengthy when we write programs based on the OOP model.
* Writing programs in OOP is not simple. Developers need to be highly proficient in OOP concepts. Simply put, OOP languages have a steep learning curve.
* We cannot apply OOP everywhere simply because it is not a universal method
* OOP programs occupy more memory than procedural languages
* OOP programs run slower than procedural languages.
5 .
What is the use of a VPN?
VPN refers to Virtual Private Network (VPN). It is the software with which we can access the internet securely. With VPN, we can mask our identities by hiding our IP addresses and making our connection purely private.

Know that there are two types of VPN: site-to-site and remote access.

The main thing about VPN is that it encrypts data in real-time and protects it from vulnerabilities. So users can transfer sensitive data to other networks or devices without worrying about eavesdropping or cyber-attacks.
6 .
Outline the prime functions of MRU and LRU.
LRU refers to the Least Recently Used algorithm, whereas MRU refers to the Most Recently Used algorithm.

LRU is the cache algorithm that first discards the data items that are less used in caches. This algorithm performs this operation when the cache is full.

On the contrary, MRU is another cache algorithm that first discards the memory elements mostly used in a cache.
7 .
What do you understand by the MERN stack?
MERN stack creates a 3-tier architecture with the help of backend, frontend, and database components. It combines four primary technologies that we use to create dynamic web applications. The four technologies are MongoDB, ReactJS, ExpressJS, and NodeJS.

Here, MongoDB is the NoSQL database management system. ExpressJS is nothing but a backend web application framework. ReactJS is a JavaScript library. The final one, NodeJS, is the JS runtime environment.
8 .
What exactly is structured programming?
Most of the latest programming languages use the structured programming model. It is a programming approach that helps to write readable and reusable codes. It is also known as modular programming.

In structured programming, programs are usually divided into many modules. The modules have many elements. Further, elements are divided into many blocks based on the related logic. Overall, it simplifies maintenance and improves the readability of codes.
9 .
Mention the different iteration statements of C++.
Below are the different iteration statements of C++.

While – This statement is evaluated at the top of a loop

For – This statement is evaluated at the top of a loop

Do – This statement is evaluated at the bottom of a loop
10 .
What do you understand by NUMA architecture?
NUMA stands for Non-Uniform Memory Access. This architecture is preferred when systems have multiple processors. In this architecture, processors access memory faster. Mainly, they can access local memory faster than non-local memory. As a result, we can improve system performance to higher levels.

The main thing about this architecture is that local memory is placed near processors, allowing quick memory access. It also reduces latency remarkably.
11 .
Give a list of the different types of operating systems you are familiar with. Include some examples of each type of operating system as well.
The following are some of the several types of operating systems:

* Distributed Operating Systems: A distributed operating system (DOS) is software that manages numerous computers as if they were one.

* Batch Operating System: This operating system interacts with the computer indirectly. There is a worker who organises linked jobs into batches based on their requirements. It is the operator's responsibility to group jobs that have comparable needs together.

* Real-Time Operating Systems: Real-Time Operating Systems (RTOS) are employed in situations when a significant number of events, the bulk of which are external to the computer system, must be accepted and processed quickly or within a tight deadline. Industrial control, telephone switching equipment, aircraft control, and real-time simulations are examples of such uses.

* Network Operating Systems: Network Operating Systems allow computers with different operating systems to join the same network. It's routinely used in the name of security.

* Time-Sharing Operating System: A time-sharing operating system allows numerous people to use the same computer at the same time. This operating system makes the most of the available resources.


Some examples of operating systems are as follows:

* Microsoft Windows is an operating system developed by Microsoft (Graphical User Interface Operating System based for Personal Computers)

* iOS is Apple's mobile operating system (iPhone, iPad, and iPod Touch operating system)

* MacOS is the operating system that runs on Apple's personal computers and workstations, such as the MacBook and iMac.

* GNU or Linux (for Personal Computers, File and Print server, Workstations, ISP, Three-tier Clients and Servers)

* Android (Google's mobile operating system for smartphones, tablets, smartwatches, and other devices) is a mobile operating system developed by Google.
12 .
What do you know about demand paging in operating systems?
Demand paging in operating systems is a strategy for loading pages (a page is the smallest unit of data for memory management in a virtual memory operating system). A page frame is the smallest contiguous unit of physical memory with a predetermined length into which the operating system maps memory pages) only when they are needed. Virtual Memory is a storage allocation method that makes it possible to address secondary memory as if it were the main memory. The addresses used by a program to refer to memory are different from the addresses used by the memory system to designate physical storage sites, and the addresses created by the program are automatically converted to machine addresses. The quantity of secondary memory available is defined by the number of main storage sites available rather than the actual number of main storage locations, and the capacity of virtual storage is restricted by the computer system's addressing scheme.

When a place on the page is addressed during execution, the page is only brought into memory. The following are the steps for getting a page into the main memory or demand paging:

* An attempt is made by the operating system to visit the page.

* If the page is valid, the CPU proceeds to process instructions as usual (in memory).

* When a page is wrong, the operating system performs a page fault trap.

* The operating system then examines the memory reference to see if it is a valid reference to a secondary memory location. The process will be cancelled if this is not the case (illegal memory access). Otherwise, the operating system will have to read the page from the main memory.

* The operating system arranges a disc operation to read the desired page into the main memory.

* The operation that was paused as a result of the operating system trap is then restarted or continued.
13 .
Highlight some of the drawbacks of inheritance.
The following are some of the drawbacks of inheritance:

* Looking at different classes for different purposes frequently increases the amount of time and effort required to complete a program.

* The classes of parent and kid become closely intertwined.

* Any program adjustments would entail revisions in both parent and child classes.

* It demands meticulous implementation; else, incorrect outcomes will happen.
14 .
Explain the benefits and drawbacks of Object-Oriented Programming Languages.
Some of the benefits of adopting Object-Oriented Programming Languages are as follows:

* Object-Oriented Programming Languages (OOPs) are programming languages that employ a bottom-up approach, allowing programmers to replicate the real world and its constituents.
* Object-Oriented Programming Languages reduce the amount of code that programmers have to write.
* Code may be easily changed and extended without impacting other capabilities.
* Object-Oriented Programming Languages demand a long and thorough design phase, which results in a better design with fewer faults.
* It makes code reusability possible.
* Object-Oriented Programming Languages (OOPLs) help programmers achieve their objectives faster.
* Object-Oriented Programming Languages (OOPLs) are languages that break down a large problem into smaller pieces.
* When abstraction is applied, the user is not exposed to superfluous data.

Some of the drawbacks of utilising Object-Oriented Programming Languages are as follows:

* It takes a lot of planning to use these languages effectively.
* These aren't ideal for little concerns because they complicate things too much.
* Classes in Object-Oriented Programming Languages have a tendency to be overly wide.
* In some situations, programs written in Object-Oriented Programming Languages may consume a significant amount of memory, which is obviously undesired.
15 .
Give the definition of abstract classes. Can we make objects or instances of these classes?
An abstract class is a type of class that has abstract methods. The abstract classes do not define these methods, despite the fact that they are declared. These methods must be provided in a subclass only if they are to be used in that subclass.

No, we can't make abstract classes into objects or instances. There can be no instances of an abstract class since it lacks a complete implementation. Subclasses that inherit the abstract class can be used to create instances.
16 .
In distributed systems, what do you understand about the fundamental model?
Distributed systems are fragile and sophisticated. These models assist designers in resolving major design concerns, obstacles, or risks so that they can construct a system that is both dependable and secure without losing any of its proper objectives, such as bandwidth optimization for performance reasons.

Firewalls and ACLs govern network traffic flow via them; Access Control Lists restrict who has access based on rules defined by users inside their respective organisations' policies. These are examples of the fundamental models being referred to. These controls ensure that data does not leak outside of an organization's firewall while simultaneously giving it some control.
17 .
State the delivery guarantees with the following techniques in Distributed systems: best effort, at least once, at most once?
In distributed systems, the following are some common "message delivery approaches":

* At Most Once: When sending a message from the sender to the receiver via at-most-once message delivery, there is no guarantee that they will receive it. Not all messages will be sent, and if you try to solve the problem yourself by attempting delivery at least once or using a different mechanism like batching, you will fail.

* At Least Once: The at-least-once strategy to sending communications means that either the sender or the recipient of a message must actively participate and ensure that there is no way of knowing if it will be received every time they transmit it. To ensure that each message is sent, either the sender must notice a failure and resend the message, or the receiver must continually request messages that have not been delivered. The message recipient might be either a sender who continues to send messages until they obtain a response or someone who refuses to give up and keeps dragging them in.

* Exactly Once: With the at-least-once messaging strategy, we can only hope that our processes result in certain messages being delivered several times. Ideally, we'd like to have messages delivered exactly once. However, life isn't always fair, and you can't always get what you want!
18 .
What do you understand about Design Patterns? What are their uses?
A design pattern is a generic repeatable solution to a typically occurring problem in software design in software engineering. A design pattern isn't a finished design that can be turned into code right away. It is a description or template for solving an issue that may be applied to a variety of scenarios.

Patterns in Design are used in a variety of ways. Design patterns can help developers save time by providing tried and true development paradigms. Effective software design necessitates taking into account challenges that may not be apparent until later in the implementation process. For coders and architects familiar with the patterns, reusing design patterns helps to eliminate subtle flaws that can lead to large difficulties and improves code readability. People frequently only know how to apply certain software design techniques to specific situations. These methods are challenging to apply to a broader set of issues. Design patterns are generic solutions that are documented in a way that does not necessitate specifics connected to a specific situation. Patterns help engineers to speak about software interactions using well-known, well-understood terms. Compared to ad-hoc designs, common design patterns can be improved over time, making them more robust.
19 .
Explain the different types of classloaders in Java.
Java Virtual Machine or JVM's Classloader subsystem has the responsibility of loading class files. On the execution of a Java application, the classloader is loaded firstly. The following are Java's three built-in classloaders:

Extension ClassLoader: This is the parent of System ClassLoader and the child of Bootstrap ClassLoader. The $JAVA_HOME/jre/lib/ext directory's jar files are loaded by it.

ClassLoader in Bootstrap: ClassLoader is the superclass of Extension classloader, which is the default classloader in Bootstrap. It loads the rt.jar file, which contains all Java Standard Edition class files, including java.lang, java.net, java.util, java.io, and java.sql package classes and many more.

System or Application ClassLoader: System/Application ClassLoader is an extension classloader's child classloader. The classpath is used to load the class files. By default, the classpath is set to the current directory. To change the classpath, use the "-cp" or "-classpath" switches. Another name for it is application classloader.
20 .
State your understanding of Distributed Database Management Systems with Transparency?
The transparent Distributed Database Management System is a type of database management system that hides the physical structure of the database from users. Physical structure, also known as physical storage structure, refers to the memory manager of a database management system and describes how data is saved on a disk. There is less abstraction as a result of this. In Distributed Database Management Systems (or DDBMS), there are four forms of transparency:

* Transparency in transactions
* Transparency in performance
* Transparency in relational databases
* Transparency in distribution
21 .
Define destructors in C++. Give the syntax for Destructors in C++.
In C++, destructors are instance member functions that are called automatically when an object is destroyed. A destructor, in other terms, is the final function called before an object is destroyed. It's worth noting that if an object was created with the "new" keyword, or if the constructor used the "new" keyword to allocate memory from the heap memory or the free store, the memory should be freed with the "delete" keyword in the destructor. Destructors are called for a class object when it goes out of scope or is expressly removed, and they are used to deallocate memory and do the additional cleanup for the object and its members when the object is destroyed.

In C++, a destructor has the following syntax: ~constructorName();

Hence, for instance, if the name of the class is "Complex", the destructor of the class would be as follows (the name of the constructor would be "Complex"):
~Complex();​
22 .
What are distributed systems? State some examples of distributed systems.
Distributed systems are a sort of software environment or computer system in which various components are distributed among multiple computing devices (or other devices) through the internet. These networks divide and coordinate the work so that it may be accomplished more quickly than if one computer or device handled everything alone. It simply implies "distributed" as opposed to "centralised" or having a single point of contact for all communications and processing amongst computing equipment. Distributed file systems, for example, allow computer applications to see several physical storage devices, such as disc drives, as a single huge storage resource. Although the distributed operating system handles different resources, it appears to users as a single entity with its own namespace (e.g., files are given names independent of their location). By utilising dispersed resources to increase data locality, distributed systems have the potential to achieve excellent performance and availability. Because it provides concurrent processing capacity of all computers involved, distributed computing allows us to attain larger scalability than a single computer could, offering redundancy against equipment failures or scheduled maintenance downtime. A distributed architecture usually entails distribution across physical hardware, which is more complicated but has advantages over sharing a single large server, such as the ability to use specialised hardware designed to improve computational efficiency, reliability, and fault tolerance while also allowing applications to use computing resources located close together (reducing latency).

The following are some of the most common distributed system examples:

* A Distributed System is exemplified by the telephone system and cellular networks.

* The World Wide Web is another distributed system that allows people to connect with one another via computers all over the world, creating a virtual community in which anything can happen.

* Computation in parallel is an example of a Distributed System.

* Aircraft control systems use similar ideas, combining data from multiple sources to tell planes not only where they're heading but also how fast or slow they should fly based on wind conditions and other factors.

* BitTorrent and other peer-to-peer networking apps (for downloading).
23 .
How does OpenMP make it possible to program in shared memory?
To control the automatic creation of threads in OpenMP, pragmas are used. The threads share memory because they share the address space. They do, however, have access to a local view of the shared variables via "private" variables. Each thread gets its own variablecopy, which the compiler can optionally initialise with the original variable. The references to private variables are statically updated to the new variables within the thread.
24 .
Define cache coherence and hypercube connection. For a node hypercube, what will be its diameter?
Cache coherence simply means that different processors might keep their own local caches. As a result, there could be several copies of the same data. Access to the local copies behaves similarly to access from the local copies, with the exception of access time. A hypercube is a single node. An n node hypercube is made up of two n/2 node hypercubes connected by their respective nodes. An n node hypercube has a diameter of log(n). The diameter is nothing but the smallest number of links needed to connect the two farthest nodes.
25 .
What do you understand about SMID?
SMID stands for single instruction multiple data and is a class in Flynn's taxonomy of parallel architectures. Different processing elements in this architecture all execute the same instruction in the same clock cycle, with the respective data (e.g., in registers) being independent of one another.
26 .
Write a C++ program to find pairs in a given array.
Program:
main.cpp
#include <bits/stdc++.h>
     using namespace std;
      void printPairs (int arr[ ], int n)
        {
          for (int i = 0; i < n; i++) {
              for (intj = 0; j< n; j++ ) {
              cout <<”(“ <<arr[i] <<”,”
                   <<arr[j]<<”)”
                         <<”,”;
                  }
           }​

 Output:
/tmp/v4DdQImt.o
(1, 1), (1, 2), (1, 3), (2, 1), (2, 2),  (2, 3), (3, 1), (3, 3), (3, 3), ​
27 .

It is executed just before destroying objects.

It is executed soon after the ‘try and catch’ block is executed.

29 .
Explain the different types of locking mechanisms in DBMS.
There are two types of locks in DBMS: exclusive lock and shared lock.

* When it comes to the shared lock, it provides read-only permission to users to access data in a database. To put it another way, users can only read the data, but they cannot modify it.

* When it comes to the exclusive lock, it allows users to read and write data in a database. The important thing is that we can access data only once.
30 .
Write Python code to find the position of a character.
Program:

match= (re.search( pattern, string ))
print ( “ starting index”, match. start())
print ( “start and end index”, match.span())​

Output:
starting index 4
start and end index ( 4, 7)​
31 .
Compare HTTP and HTTPS.

35 .
How many types of memory areas are allocated by Java Virtual Machine in Java?
The following are the several types of memory areas allocated by the Java Virtual Machine:

* Class(Method) Area: The Class(Method) Area keeps track of per-class structures such as the runtime constant pool, fields, method data, and method code.

* Program Counter (PC) Register: The PC (program counter) register stores the address of the Java virtual machine instruction currently being executed.

* Stack: Frames are kept in the Java Stack. Local variables and partial results, as well as invoking and returning methods, are all managed by it. Each thread has its own JVM stack, which is created at the same time as the thread. A new frame is created each time a method is called. When the method invocation of a frame is complete, it is destroyed.

* Native Method Stack: The Native Method Stack contains every single native method utilised in the application.

* Heap: This is where the objects' memory is allocated during runtime.
