7. Two pings were issued from a host on a local network. The first ping was issued to the IP address of the default gateway of the host and it failed. The second ping was issued to the IP address of a host outside the local network and it was successful. What is a possible cause for the failed ping?

The default gateway device is configured with the wrong IP address.
The TCP/IP stack on the default gateway is not working properly.
The default gateway is not operational.
Security rules are applied to the default gateway device, preventing it from processing ping requests. *

D. If the ping from one host to another host on a remote network is successful, this indicates that the default gateway is operational. In this scenario, if a ping from one host to the default gateway failed, it is possible that some security features are applied to the router interface, preventing it from responding to ping requests.

8. Which command is used to manually query a DNS server to resolve a specific hostname?

net
tracert
nslookup *
ipconfig /displaydns

C. The nslookup command was created to allow a user to manually query a DNS server to resolve a given host name. The ipconfig /displaydns command only displays previously resolved DNS entries. The tracert command was created to examine the path that packets take as they cross a network and can resolve a hostname by automatically querying a DNS server. The net command is used to manage network computers, servers, printers, and network drives.
