Two client subnets need different default gateways and DNS servers. Where should you set these DHCP options so each subnet can receive its own values?

  2. B

    The client commonly did not obtain a DHCP lease.

  3. C

    The address proves that the scope has no free addresses.

A packet capture shows no DHCP Discover from a client. Which checks are most relevant as initial troubleshooting steps? Select all that apply.

  1. A

    Verify that the client adapter is enabled and the network link works.

  2. B

    Confirm that the client is connected to the intended VLAN.

  3. C

    Start by checking whether the server has a free address in its scope.

  4. D

    Investigate whether a local broadcast-path issue is preventing the Discover from being sent or observed.

A device has a manually configured static address that currently falls inside the DHCP dynamic pool. What should an administrator do to prevent the server from leasing that address to another client?

  1. A

    Create a reservation so the manually configured device must request its address through DHCP.

  2. B

    Keep the static address outside the dynamic pool or exclude it from allocation.

  3. C

    Shorten the scope lease duration so the address is reclaimed sooner.

  4. D

    Set the address as the subnet ID.

  2. B

    Create a separate scope for each client subnet.

  3. C

    Create a scope only for the subnet with more clients.

A router has a manually configured address that falls inside a proposed DHCP range. What should the administrator do before activating the scope to prevent DHCP from leasing that address?

  1. A

    Leave the address in the pool and shorten the lease.

  2. B

    Create a reservation for every manually configured device.

  3. C

    Exclude the address from dynamic allocation or adjust the pool so it is outside the range.

  2. B

    Set the differing DNS option only at the server level.

  3. C

    Create a reservation for each client that needs the DNS setting.

    Use shorter leases to recycle addresses faster.

  3. C
