1. What is the significance of CCNA certification?

CCNA certification validates the foundational knowledge and skills required to operate, configure, and troubleshoot small to medium-sized networks. It demonstrates your ability to work with network devices such as routers, switches, and basic security appliances.

2. What are the different types of network topologies?

The main types of network topologies are:

  • Bus Topology
  • Star Topology
  • Ring Topology
  • Mesh Topology
  • Tree Topology

Each topology has its unique characteristics, advantages, and disadvantages.

3. What is subnetting and why is it important?

Subnetting is the process of dividing a network into smaller subnetworks called subnets. It helps in efficient utilization of IP addresses, improves network performance, and enhances network security by segregating different departments or network segments.

4. Explain the differences between TCP and UDP protocols.

TCP (Transmission Control Protocol) is a connection-oriented protocol that offers reliable, ordered, and error-checked data transmission. It guarantees that all sent packets will reach the destination in the correct order.

UDP (User Datagram Protocol), on the other hand, is a connectionless protocol that provides fast and lightweight transmission. It does not guarantee reliable delivery, ordered data transfer, or error checking.

5. How does ARP (Address Resolution Protocol) work?

ARP is used to map an IP address to a physical (MAC) address on a local network. When a device wants to send data to another device, it first checks its ARP cache. If the destination IP address is not found, an ARP request is broadcasted, asking “Who has this IP address?”. The device with the corresponding IP address responds with its MAC address, allowing communication to occur.
