VLAN stands for Virtual Local Area Network, used to segment a network into multiple isolated networks for security and performance purposes.
VLANs allow for logical segmentation of a network, improving security and performance.
Devices within the same VLAN can communicate with each other as if they were on the same physical network.
VLANs are commonly used in enterprise networks to separate different departments or functi...
- Q9. ISO Model and how many layers?
- Ans.
The ISO model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven layers.
The ISO model stands for International Organization for Standardization model.
It consists of seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.
Each layer has specific functions and communicates with the adjacent layers for data transmission.
For ...
- Q10. What is switching and routing?
- Ans.
Switching is the process of forwarding data packets between devices on the same network, while routing is the process of forwarding data packets between different networks.
Switching operates at Layer 2 of the OSI model, using MAC addresses to forward packets within a network.
Routing operates at Layer 3 of the OSI model, using IP addresses to forward packets between networks.
Switches create broadcast domains, while rout...
- Q11. What is proxy and DHCP?
- Ans.
Proxy is an intermediary server that separates end users from the websites they browse. DHCP is a network protocol that assigns IP addresses to devices.
Proxy server acts as a middleman between a user and the internet, providing anonymity and security.
DHCP dynamically assigns IP addresses to devices on a network, simplifying network administration.
Proxy servers can be used to bypass content restrictions or improve netwo...
- Q12. What is the BGP and why it used?
- Ans.
BGP stands for Border Gateway Protocol, used for routing between different autonomous systems on the internet.
BGP is a standardized exterior gateway protocol used to exchange routing information between different autonomous systems (AS).
It helps in determining the best path for data packets to travel between networks.
BGP is crucial for ensuring efficient and reliable internet connectivity.
It allows network administrato...
- Q13. What are the routing& routed protocol?
- Ans.
Routing protocols determine how data packets are forwarded across a network, while routed protocols define the format of the packets.
Routing protocols are used by routers to determine the best path for forwarding data packets.
Examples of routing protocols include RIP, OSPF, and BGP.
Routed protocols are used to format the data packets themselves, such as IP or IPv6.
Examples of routed protocols include TCP/IP, UDP, and I
- Q14. What is ospf, Rip, igrp, eigrp protocols?
- Ans.
OSPF, RIP, IGRP, and EIGRP are routing protocols used in networking to determine the best path for data packets to travel.
OSPF (Open Shortest Path First) is a link-state routing protocol that uses Dijkstra's algorithm to calculate the shortest path.
RIP (Routing Information Protocol) is a distance-vector routing protocol that uses hop count as a metric to determine the best path.
IGRP (Interior Gateway Routing Protocol) ...
- Q15. What are the VLAN Types?
- Ans.
VLAN types include default, data, voice, management, and native VLANs.
Default VLAN: VLAN 1 is the default VLAN on Cisco switches.
Data VLAN: Used for data traffic.
Voice VLAN: Used for voice traffic.
Management VLAN: Used for managing network devices.
Native VLAN: Untagged VLAN used for trunking.
- Q16. Tell some router commands?
- Ans.
Router commands are used to configure and manage routers in a network.
show ip interface brief - displays a summary of the router's interfaces and their IP addresses
show running-config - displays the current configuration of the router
interface [interface name] - enters interface configuration mode for a specific interface
ip route [destination network] [subnet mask] [next hop IP] - adds a static route to the routing tab
- Q17. What is the subnet mask and types?
- Ans.
Subnet mask is a 32-bit number used to divide an IP address into network and host portions.
Subnet mask is used to determine which part of an IP address is the network portion and which part is the host portion.
There are different types of subnet masks such as Classful subnet masks, Classless subnet masks, and Variable Length Subnet Masks (VLSM).
Examples of subnet masks include 255.255.255.0 (Class C), 255.255.0.0 (Clas

- Q3. Runtime polymorphism and how it works vptr and vtable
- Ans.
Runtime polymorphism in C++ is achieved through virtual functions, vptr (virtual pointer), and vtable (virtual table).
Runtime polymorphism allows objects of different classes to be treated as objects of a common superclass.
Virtual functions are declared in a base class and overridden in derived classes to achieve polymorphism.
vptr is a pointer that points to the vtable of an object, allowing dynamic binding of virtual ...
- Q4. Which version of c++ you use
- Ans.
I primarily use C++17, but I am familiar with earlier versions as well.
I am comfortable working with features introduced in C++17 such as structured bindings and constexpr if
I have experience with earlier versions like C++11 and C++14
I stay updated with the latest features and improvements in C++ standards

- Q6. Have you used any windows api's?
- Ans.
Yes, I have used Windows API's extensively in my previous projects.
I have used Windows API's for tasks such as creating windows, handling messages, and interacting with system resources.
Examples include using functions like CreateWindow, SendMessage, and ReadFile.
I have also worked with specific Windows API's like Winsock for networking and WinINet for internet-related tasks.

- Q2. What is dynamic_cast where it can fail and what will happen in that case
- Ans.
dynamic_cast is a C++ operator used for safe downcasting of pointers and references in polymorphic classes.
dynamic_cast is used to safely downcast a pointer or reference from a base class to a derived class.
It can fail if the object being casted is not of the target type, in which case it returns a null pointer for pointers or throws a std::bad_cast exception for references.
Dynamic_cast can only be used with pointers o...

- Q2. What is union in c++
- Ans.
Union in C++ is a data structure that allows storing different data types in the same memory location.
Unions are similar to structures but all members share the same memory location.
Only one member of a union can be accessed at a time.
Unions are useful when you need to store different data types in the same memory space.
Example: union MyUnion { int i; float f; };
Example: MyUnion u; u.i = 10; // Accessing integer member
- Q3. What is weak pointer
- Ans.
Weak pointer is a type of smart pointer in C++ that does not control the lifetime of the object it points to.
Weak pointers are used to break circular references in shared pointers.
They do not increase the reference count of the object.
They are used in scenarios where the object may be deleted while there are still weak pointers pointing to it.
- Q4. What are processes and threads memory is allocated to what process or threads? what is mutex and semaphore how many threads/process can you launch at a time what is meaning of core in 4-core system what is...
- Ans.
Processes and threads are units of execution in a computer system. Memory is allocated to processes. Mutex and semaphore are synchronization mechanisms. Core refers to a processing unit in a multi-core system. Context switching is the process of switching between different processes or threads.
Processes are independent units of execution with their own memory space and resources.
Threads are lightweight units of executi...
