6. Top 10 CCNA Interview Questions and Sample Answers

Here are some commonly asked CCNA interview questions along with sample answers:

  1. Question: What is the difference between a router and a switch?
  2. Sample Answer: A router is a networking device that connects multiple networks and forwards data packets between them. It operates at the network layer of the OSI model. On the other hand, a switch is a networking device that connects devices within a network. It operates at the data link layer of the OSI model and uses MAC addresses to forward data.

  3. Question: What is subnetting?
  4. Sample Answer: Subnetting is the process of dividing a network into smaller subnetworks called subnets. It allows for efficient use of IP addresses and improves network performance and security.

  5. Question: What is a VLAN?
  6. Sample Answer: A VLAN (Virtual Local Area Network) is a logical grouping of devices within a network, regardless of their physical location. VLANs provide enhanced security, flexibility, and scalability by isolating traffic between different VLANs.

  7. Question: How does ARP (Address Resolution Protocol) work?
  8. Sample Answer: ARP is used to resolve an IP address to a MAC address on a local network. When a device wants to send a packet to another device on the same network, it sends an ARP request asking for the MAC address associated with the destination IP address. The device with the corresponding IP address responds with its MAC address, and the sender can then encapsulate the packet with the destination MAC address and send it.

  9. Question: What is the purpose of access control lists (ACLs)?
  10. Sample Answer: ACLs are used to control network traffic by permitting or denying the flow of packets based on set rules. They are implemented on routers or switches to provide security and manage network resources effectively.
