  1. What is NAT (Network Address Translation) primarily used for in enterprise networks?

    Answer: To translate private IP addresses to public IP addresses for Internet access

    NAT translates private RFC 1918 IP addresses used internally to a public IP address for Internet communication, conserving public IPv4 address space.

  2. Which type of NAT maps many internal private addresses to a single public IP address using unique port numbers?

    Answer: PAT (Port Address Translation)

    PAT (Port Address Translation), also called NAT overload, maps multiple internal hosts to a single public IP by differentiating connections using unique TCP/UDP port numbers.

  3. What is the administrative distance of a directly connected route on an Aruba AOS-CX router?

    Answer: 0

    Directly connected routes have an administrative distance of 0, representing the most trusted route source since the network is physically attached to the device.

  4. Which command on Aruba AOS-CX displays the IPv4 routing table?

    Answer: show ip route

    The 'show ip route' command on Aruba AOS-CX displays the IPv4 routing table, showing all learned and configured routes with their sources and next-hop information.

  5. What does DNS (Domain Name System) do in an IP network?

    Answer: Translates human-readable domain names to IP addresses

    DNS resolves human-readable domain names (e.g., practicetestgeeks.com) into IP addresses that routers and switches use to forward packets to the correct destination.

  6. What is the purpose of the default route (0.0.0.0/0) in an IP routing table?

    Answer: To match any destination not covered by a more specific route, typically sending it toward the Internet

    The default route (0.0.0.0/0) is a catch-all route that forwards packets to a specified next-hop when no more specific route matches, commonly used to direct traffic to an Internet gateway.
