Question 2

Instead of using ping on an IP address, you can ping a server by host name or FQDN.

Failure to resolve the host name or FQDN could be caused by a number of issues. Briefly discuss these issues.

Accepted Answer

Failure to resolve the host name or FQDN could be caused by any of the following issues:
•Improperly configured client-The client does not have the correct DNS servers or domain suffixes.
•Network failure-The client cannot route queries to the DNS server because of a network related failure, such as a bad switch port or powered-off router
DNS server failure-The server is not available for the client, such as when a hardware failure occurs or the DNS server service is not running.
