(updated)question correctly answered
What routing table entry has a next hop address associated with a destination network? - correct answer
✔✔remote routes
If the default gateway is configured incorrectly on the host, what is the impact on communications? -
correct answer ✔✔The host can communicate with other hosts on the local network, but is unable to
communicate with hosts on remote networks.
Why is NAT not needed in IPv6? - correct answer ✔✔Any host or user can get a public IPv6 network
address because the number of available IPv6 addresses is extremely large.
Which term describes a field in the IPv4 packet header that contains a unicast, multicast, or broadcast
address? - correct answer ✔✔destination IPv4 address
