Interview Process

Nutanix Technical Interview Questions for Freshers and Experienced

One of the common questions asked in a technical interview is:

1. What is the difference between a MAC address and an IP address?

A MAC (Media Access Control) address is a unique identifier assigned to a network interface controller (NIC) for communicating on the physical network. It is a permanent hardware address assigned by the manufacturer of the NIC. On the other hand, an IP (Internet Protocol) address is a logical address assigned by the administrator to identify a device on the network. It is used to provide a routing path to the device for communication on the network. Unlike MAC addresses, IP addresses can be dynamic and may change over time.

Understanding the OSI Model and its Seven Layers

The OSI (Open Systems Interconnection) Model is a conceptual model used to explain how different devices communicate on a network. It comprises seven layers, each with a specific set of functions. Here are the seven layers in the OSI Model:

1. The Physical Layer - This layer provides the means for transmitting data between devices, including the type of cable, connectors, and electrical signals.

2. The Data Link Layer - This layer provides error-free transfer of data frames between devices over the physical layer.

3. The Network Layer - This layer is responsible for addressing and routing of data packets across multiple networks.

4. The Transport Layer - This layer ensures reliable delivery of data between devices and handles end-to-end error recovery.

5. The Session Layer - This layer establishes, manages, and terminates sessions between applications running on different devices.

6. The Presentation Layer - This layer deals with data translation and encryption for secure communication.

7. The Application Layer - This layer enables communication between application processes running on different devices, provides network services to applications, and includes protocols such as HTTP, FTP, SMTP, etc.

Understanding the OSI Model and the various functions of each layer can help in troubleshooting network issues and designing more efficient networks.

Encapsulation in Object-Oriented Programming

Encapsulation in object-oriented programming is a concept that allows for the bundling of data and methods within a single unit and restricting access to an object's internal data from the outside world. In other words, it involves the concept of hiding data and implementation details to prevent unauthorized access, modification, or misuse of an object's data properties. This is done by defining the object's properties and methods as either public or private, with private methods and properties only accessible within the class itself. Encapsulation allows for better control and security of an object's data and behavior, making the code more modular, easy to maintain, and less prone to errors.

// Example implementation of encapsulation in JavaScript

class Car {
  constructor(make, model, year) {
    this._make = make;
    this._model = model;
    this._year = year;
  // public methods
  getMake() {
    return this._make;
  setMake(make) {
    this._make = make;
  // private method
  #privateMethod() {
    console.log("This is a private method.");

const myCar = new Car("Toyota", "Corolla", 2020);
console.log(myCar.getMake()); // "Toyota"

// Attempt to access private method (will result in error)
myCar.#privateMethod(); // Uncaught SyntaxError: Private field '#privateMethod' must be declared in an enclosing class

Understanding Virtualization and Its Benefits

Virtualization is a technology that allows multiple operating systems to run on a single physical computer. It involves dividing a single physical server into multiple virtual servers, each with its own operating system and independent environment. The virtual servers share the resources of the underlying physical computer, such as CPU, memory, and storage.

The benefits of virtualization include:

1. Efficient use of resources: Since the physical server is divided into multiple virtual servers, the resources are used more efficiently, leading to increased server utilization and reduced hardware costs.

2. Simplified management: Virtualization allows central management of all virtual servers, making it easier to manage and monitor them.

3. Improved disaster recovery: Since the virtual servers are independent of each other, in the event of a disaster, it is easier to recover the virtual servers than the physical servers.

4. Increased flexibility: Virtualization makes it easier to move virtual servers between physical servers, making it possible to balance the workload and avoid downtime.

Overall, virtualization is a powerful technology that can help businesses reduce costs, simplify management, and increase flexibility.

Types of Virtualization

Virtualization is an important concept in computing that allows for the creation of virtual resources from physical resources. Here are the different types of virtualization:

1. Full virtualization: This allows the creation of a complete virtual machine that emulates the underlying hardware. It is possible to run multiple operating systems on a single physical machine using full virtualization.

2. Para-virtualization: Para-virtualization allows multiple operating systems to run on a single physical machine. However, it requires modification of the operating systems running on the virtual machines to make them aware of their virtualization environment.

3. Operating system (OS) virtualization: OS virtualization allows multiple instances of an operating system to share the same physical resources. Each instance is isolated from the others to prevent any interference.

4. Application virtualization: Application virtualization allows the creation of a virtual environment for an application. This allows the application to run on any compatible operating system without installation or modification.

5. Network virtualization: Network virtualization creates a virtual representation of a physical network. This allows for the creation of virtual networks that can be used independently from the physical network.

There are also other types of virtualization, such as storage virtualization and memory virtualization, which are used to create virtual storage and virtual memory, respectively.

Commonly Used Linux Commands

Here are some of the most common Linux commands:


- List files and directories


- Change directory


- Print working directory


- Make directory


- Remove directory


- Copy files and directories


- Move or rename files and directories


- Remove files and directories


- Change file permissions


- Execute command as superuser

These commands can be used in the Linux terminal to perform various tasks. It is important for Linux users to be familiar with these commands in order to effectively navigate and manage their system.

Explanation of Reference Counting Mechanism in the Context of Garbage Collection

Reference counting is a mechanism used in garbage collection to keep track of the number of references to an object in memory. It works by keeping a count of the number of references to an object and releasing memory when the count reaches zero.

For example, imagine we have an object called "myObject" with a reference count of 2. This means that there are two variables or objects that are pointing to "myObject". If one of those references is deleted or goes out of scope, the reference count will decrease to 1. If the second reference is deleted or goes out of scope, the reference count will reach 0, and the memory allocated for "myObject" can be safely freed.

Reference counting has its advantages, such as being a simple and fast method of garbage collection that can operate incrementally and can deal with cycles of references. However, it also has its limitations, such as the overhead involved in maintaining the reference counts and the inability to handle circular references if not implemented correctly.

Overall, reference counting is a powerful tool used in garbage collection to efficiently manage memory, but developers must be careful to ensure that it is implemented correctly to avoid any potential memory leaks.

Out of Memory Error Exception in Java

The OutOfMemoryError Exception occurs when Java applications run out of memory allocated by the JVM (Java Virtual Machine). This occurs when an application tries to allocate more memory than what is available in the heap.

Java has a garbage collector which automatically frees up unreferenced objects. However, it is still possible for applications to exhaust the heap memory due to excessive allocation of large objects or memory leaks.

To fix this error, you can increase the heap size allocated to the JVM using the -Xmx option. It is also important to carefully manage object creation and destruction, to prevent memory leaks and excessive memory usage.

Overall, it's important to monitor and manage memory usage in Java applications to prevent OutOfMemoryError and ensure smooth functioning of your software.

Difference between Public Cloud and Enterprise Cloud

A public cloud is a type of cloud computing in which the resources (such as storage and servers) are provided over the internet by a third-party cloud service provider and can be accessed by anyone on the internet. On the other hand, an enterprise cloud is a private cloud computing environment used by a single organization for their own purposes.

The key differences between public and enterprise clouds are their scalability, security, and accessibility. Public clouds can offer infinite scalability due to their vast resources, but may have lower security due to their accessibility from the internet. Enterprise clouds, on the other hand, offer higher levels of security and accessibility due to their private nature, but may have limited scalability.

In summary, public clouds are best suited for organizations that need infinite scalability without the need for high-level security, while enterprise clouds are ideal for organizations with strict security requirements and the need for more control over their cloud environment.

Enterprise Cloud: Software-Based or Hardware-Based?

This question is asking whether the enterprise cloud is based on software or hardware.

Types of Applications Available in the Enterprise Cloud

In the enterprise cloud, various types of applications are available. These applications include but are not limited to:

- Customer Relationship Management (CRM) applications - Enterprise Resource Planning (ERP) applications - Human Resource Management (HRM) applications - Supply Chain Management (SCM) applications - Business Intelligence (BI) applications

Each of these applications serves a specific purpose and helps organizations to streamline their business operations, manage customer relationships, and make data-driven decisions.

Understanding Hyperconverged Infrastructure and its Benefits

Hyperconverged infrastructure (HCI) is a software-defined IT infrastructure that combines storage, computing, and networking into a single system. It offers several benefits over traditional infrastructure, such as simplified management, increased scalability, and improved efficiency.

One of the main reasons why a company should consider implementing HCI is its ability to streamline IT operations. By consolidating all resources into a single system, HCI eliminates the need for separate management tools and processes, reducing complexity and increasing operational efficiency.

HCI also offers better scalability compared to traditional infrastructure, as it allows companies to add more resources as needed without having to disrupt the existing environment. This makes it an ideal solution for companies that need to rapidly scale their infrastructure to meet growing business demands.

In addition, HCI can improve data protection and disaster recovery capabilities by leveraging features like replication and snapshotting. This ensures that data is always available and recoverable in the event of a failure or data loss.

Overall, hyperconverged infrastructure can provide significant benefits to a company looking to modernize their IT infrastructure, improve operational efficiency, and enhance data protection capabilities.

How can HCI help the company with storage needs?

If the company requires storage, HCI (Hyper-Converged Infrastructure) can provide a solution by implementing software-defined storage to consolidate storage resources. HCI can also help by optimizing storage capacity utilization and reducing data management costs through automated data tiering. Additionally, HCI offers a more scalable and flexible approach to storage, allowing the company to easily expand storage capacity as needed.

Advantages of Ternary Search Tree over Trie

A Ternary Search Tree and Trie are data structures used for string operations. However, Ternary Search Tree has some advantages over Trie, such as:

  • Ternary Search Tree requires less memory than Trie for storing the same set of keys.
  • Search operation of Ternary Search Tree is faster than Trie because it has fewer nodes to traverse.
  • Ternary Search Tree supports ordered traversal of keys, while Trie can only do a prefix order traversal.

Overall, Ternary Search Tree is a better choice for string operations in terms of space and time complexity.

Multiplying Two Numbers using Bitwise Operators

Here is a code snippet to multiply two numbers using bitwise operators in Python:

def multiply(num1, num2): result = 0 while(num2 > 0): if(num2 & 1): result += num1 num1 <<= 1 num2 >>= 1 return result

num1 = 5 num2 = 7 print("Product of", num1, "and", num2, "is", multiply(num1, num2))

In this code, we are using bitwise operators to multiply two numbers num1 and num2. The function takes two numbers as input and returns their product.

We are initializing a variable result as 0 and iterating through the loop until num2 is greater than 0. Inside the loop, if the value of the least significant bit of num2 is 1, we add num1 to our result. Then, we left shift num1 by 1 bit and right shift num2 by 1 bit. This is equivalent to dividing num2 by 2. We repeat this process until num2 becomes 0.

Finally, we return the result. We then call the function with two sample values num1 and num2 and print the product.

This approach of using bitwise operators to multiply two numbers is faster than the conventional multiplication method.

Deleting a value from a linked list with a given pointer

If you have a pointer to a node in a linked list, but do not have a pointer to any other node in the list (not even the head), you can still delete that node from the list. The process involves copying the data from the next node into the node pointed to by the given pointer, and then deleting the next node.

Here is the code for the same:

    Node* nodeToDelete = givenPointer; // node to be deleted
    Node* nextNode = nodeToDelete->next; // next node in the list
    nodeToDelete->data = nextNode->data; // copy data from the next node to the given node
    nodeToDelete->next = nextNode->next; // point given node to the next node's next
    delete nextNode; // delete the next node

Note that this code assumes that the given pointer is not the last node in the list (i.e., it has a next node). If the given pointer is the last node, then this method cannot be used to delete it.

Finding Repeating Numbers in an Array

Given an array of size N with elements ranging from 0 to N-1, where any of these integers can occur any number of times. The task is to find the repeating numbers in the array using just constant memory space and in O(N) time complexity.

void findRepeatingNumbers(int arr[], int size) {
    int i, j; 
    printf("Repeating elements: "); 
    for(i = 0; i < size; i++) { 
        if(arr[abs(arr[i])] >= 0) // first occurrence
            arr[abs(arr[i])] = -arr[abs(arr[i])]; 
        else // repeating occurrence
            printf("%d ",abs(arr[i])); 

The above code uses the approach of changing the sign of the elements at the corresponding index in the array to negative if it is encountered the first time. If there is a repeating occurrence of the element, it will already be negative, in which case we print the absolute value of that element as a repeating number.

Finding the Order of Characters in an Alien Language using a Sorted Dictionary (Array of Words)

We are given a sorted dictionary (array of words) in an alien language, where each word consists of distinct characters. We need to determine the order of characters in this language.

def find_alien_language_order(words):
    # Create an empty dictionary to store the characters and their dependencies
    chars = {}

    # Iterate through each pair of adjacent words
    for i in range(len(words) - 1):
        word1 = words[i]
        word2 = words[i + 1]

        # Compare the characters in the current and next words
        for j in range(min(len(word1), len(word2))):
            if word1[j] != word2[j]:
                # If the characters don't match, add them to the dependency dictionary
                if word1[j] not in chars:
                    chars[word1[j]] = set()

    # Create a dictionary to store the order of characters in the alien language
    order = []

    # Iterate through each character and its dependencies
    while chars:
        # Find the characters that don't have any dependencies and add them to the order
        for char in chars.keys():
            if not chars[char]:
                del chars[char]

        # Remove the characters that are already in the order from the dependencies of the other characters
        for char, dep in chars.items():

    # Return the order of characters in the alien language
    return ''.join(order)

Implementing the Sieve of Eratosthenes in O(N) Time Complexity

// Function to implement the Sieve of Eratosthenes 
function sieveOfEratosthenes(n) { 
    // Create a boolean array "prime[0..n]" and initialize 
    // all entries it as true. A value in prime[i] will 
    // finally be false if i is Not a prime, else true. 
    let prime = new Array(n + 1).fill(true); 
    let p = 2; 
    while (p * p <= n) { 
        // If prime[p] is not changed, then it is a prime 
        if (prime[p] == true) { 
            // Update all multiples of p 
            for (let i = p * p; i <= n; i += p) 
                prime[i] = false; 

    // Print all prime numbers 
    for (let p = 2; p <= n; p++) 
        if (prime[p]) 

// Driver code 
let n = 30; 
console.log("Following are the prime numbers smaller than or equal to " + n); 

The Sieve of Eratosthenes is an algorithm to find all prime numbers up to a given range. In this implementation, we first create an array 'prime' of boolean values initialized to true, with an additional element to accommodate for 0-based indexing.

We then iterate from 2 to the square root of 'n' (which is the highest possible prime factor for any number greater than 'sqrt(n)'), and update all multiples of each prime number by setting the corresponding element in the 'prime' array to false. This is done to eliminate non-prime numbers.

Finally, we print all prime numbers by iterating over the 'prime' array and printing elements where the corresponding boolean value is true. This algorithm runs in O(n) time complexity as we only loop through the array once, setting non-prime elements to false.

Golomb Sequence

The Golomb sequence is a non-decreasing sequence of integers in which the n-th term equals the number of times the letter n appears in the sequence. The first few numbers in the sequence are 1, 2, 2, 3, 3, 4, 4, 4, 5, 5, 5, 5, 5, and so on.


def golomb_sequence(n):
    This function generates the Golomb sequence up to the given number.

    n (int): number up to which the sequence needs to be generated.

    list: Golomb sequence up to n.
    # Initializing the sequence with the first element
    sequence = [1]

    # Iterate over the remaining elements
    for i in range(1, n):
        # Get the count of i in the sequence
        countI = sequence.count(i)

        # Add the countI number of i's in the sequence
        sequence += [i] * countI

        # Add the next number in the sequence
        sequence.append(i + 1)

    return sequence

This code snippet generates the Golomb sequence up to the given number. It initializes the sequence with the first element and then iterates over the remaining elements. It gets the count of i in the sequence and adds the count number of i's in the sequence. Then, it adds the next number in the sequence. Finally, it returns the Golomb sequence up to n.
