  1. Which command verifies the current DHCP bindings (leases) on a Cisco IOS DHCP server?

    Answer: show ip dhcp binding

    'show ip dhcp binding' displays all current IP-to-MAC address mappings issued by the Cisco IOS DHCP server.

  2. A host receives a 169.254.x.x address. What does this indicate?

    Answer: The host failed to receive a DHCP lease and assigned itself an APIPA address

    169.254.0.0/16 is the APIPA (Automatic Private IP Addressing) range used when a DHCP client cannot reach a server.

  3. Which command on a Cisco router excludes the addresses 192.168.1.1 through 192.168.1.10 from being assigned by DHCP?

    Answer: ip dhcp excluded-address 192.168.1.1 192.168.1.10

    'ip dhcp excluded-address' prevents the DHCP server from leasing the specified address range to clients.

  4. What type of DNS query does a client send when it wants the DNS server to perform all recursive lookups on its behalf?

    Answer: Recursive query

    A recursive query asks the DNS server to fully resolve the name and return the final answer, performing all necessary additional queries itself.

  5. Which command configures a Cisco router to use 8.8.8.8 as its DNS server?

    Answer: ip name-server 8.8.8.8

    'ip name-server' specifies the DNS server(s) that the router will use for hostname resolution.

  6. A Cisco router has 'no ip domain-lookup' configured. What is the effect?

    Answer: Mistyped commands are not sent as DNS queries, preventing long delays

    'no ip domain-lookup' disables DNS resolution on the router, preventing mistyped CLI commands from being broadcast as DNS queries and causing delays.

  7. Which protocol allows a network device to obtain an IP address, subnet mask, default gateway, and DNS server from a single server automatically?

    Answer: DHCP

    DHCP (Dynamic Host Configuration Protocol) automatically provides clients with IP address, subnet mask, gateway, DNS, and other parameters.
