Cisco CCNA mock exam questions sample test – Question 359

.Which of the following commands will configure a router to use DNS for hostname resolution?

A. ip dns primary
B. ip domain lookup
C. ip dns server
D. ip name-server


Correct Answer: B

Explanation:
The ip domain lookup command configures the device to use DNS for hostname resolution. It must be accompanied by a command that specifies the location of the DNS server,
which is done with the ip name-server command.
The ip dns-primary command is used to configure the device as the primary DNS name server for a domain (zone) and as the start of authority (SOA) record source, which designates
the start of a zone.
The ip dns server command is used to make the device a DNS server.
