A host uses address 192.168.10.70/26. Is 192.168.10.100 in the same IPv4 subnet?

  1. A

    Yes, both are in 192.168.10.64/26.

  2. B

    No, .100 is in the next /26 subnet.

  3. C

    No, .70 is the subnet address and cannot be a host.

  4. D

    No, a /26 subnet contains only addresses ending in .64 through .95.

Select all statements that correctly describe IPv6 address configuration.

  1. A

    With SLAAC, a host can use a router-advertised prefix to form an address.

  2. B

    DHCPv6 can assign addresses or provide other configuration information.

  3. C

    Router Advertisements provide information hosts use to identify routers.

  4. D

    DHCPv6 alone should be assumed to provide the default gateway.

A host configured as 192.168.10.70/26 sends traffic to 192.168.10.100. Based on the prefix, how should the host treat this destination?

  1. A

    It can send directly on the local subnet because both addresses are in the same /26.

  2. B

    It must send the traffic to its default gateway because .100 is outside the subnet.

  3. C

    It cannot communicate with .100 because the last octet differs.

  4. D

    It must use DNS to determine whether .100 is local.

Every IPv6 subnet must use a /64 prefix, regardless of the network's design.

A small network has several manually addressed infrastructure devices and also uses DHCP for other hosts. What should the administrator do to reduce address conflicts?

  1. A

    Include the static addresses in the pool so DHCP can renew them.

  2. B

    Configure DHCP to assign the same addresses as the static devices.

  3. C

    Exclude the statically assigned addresses from the managed DHCP pool.

  4. D

    Remove the subnet mask from the DHCP configuration.
