Question 1

Correct Answer:

Verified

Nslookup

Instead of using ping on an IP address, you can ping a server by host name or FQDN. If it responds when pinging by host name, your DNS suffixes are resolving properly, you can query the proper DNS zone, and the DNS zone has an A record created for it. Failure to resolve the host name or FQDN could be caused by a number of issues. Briefly discuss these issues.

Question 2

Correct Answer:

Verified

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.
•Improperly configured DNS server-The DNS server is available. However, the necessary records (A) are not configured for the zone being requested.

The DNS zone level is the level where all the DNS zones exist, such as bentech.local and _msdcs.bentech.local. From here, what activities can you perform that will affect a specific zone?
