  1. What is the purpose of CDP (Cisco Discovery Protocol)?

    Answer: To allow Cisco devices to discover and share information about directly connected Cisco neighbors

    CDP is a Cisco-proprietary Layer 2 protocol that allows Cisco devices to advertise and discover directly connected Cisco neighbors, sharing device type, IP address, and port information.

  2. What does QoS (Quality of Service) provide in a network infrastructure?

    Answer: Prioritization of specific traffic types to ensure performance for critical applications

    QoS mechanisms classify and prioritize network traffic (e.g., voice, video) to ensure bandwidth, reduce latency, and minimize jitter for latency-sensitive applications.

  3. Which layer of the Cisco three-tier hierarchical network design model provides high-speed backbone connectivity between distribution layer devices?

    Answer: Core layer

    The Core layer in Cisco's three-tier model provides high-speed, low-latency backbone switching between distribution blocks and is optimized for speed and availability over complex policy enforcement.

  4. What is the default administrative distance of a static route in Cisco IOS?

    Answer: 1

    Static routes in Cisco IOS have a default administrative distance of 1, making them preferred over most dynamic routing protocols except directly connected routes (AD=0).

  5. What is the purpose of NAT (Network Address Translation) on a router?

    Answer: To translate private internal IP addresses to a public IP address for Internet communication

    NAT translates private (RFC 1918) IP addresses used inside a network to one or more public IP addresses for communication across the Internet, conserving public address space.

  6. Which command on a Cisco router shows the current routing table including all known routes?

    Answer: show ip route

    The 'show ip route' command displays the router's routing table, listing all known networks with their associated routing protocol, administrative distance, metric, and next-hop information.
