Refer to the exhibit. If no router ID was manually configured, what would router Branch1 use as its OSPF router ID?

• 10.0.0.1

• 10.1.0.1

• 192.168.1.100

• 209.165.201.1

Answer explanation

Explanation: In OSPFv2, a Cisco router uses a three-tier method to derive its router ID. The first choice is the manually configured router ID with the router-id command. If the router ID is not manually configured, the router will choose the highest IPv4 address of the configured loopback interfaces. Finally if no loopback interfaces are configured, the router chooses the highest active IPv4 address of its physical interfaces.

Refer to the exhibit. A web designer calls to report that the web server web-s1.cisco.com is not reachable through a web browser. The technician uses command line utilities to verify the problem and to begin the troubleshooting process. Which two things can be determined about the problem? (Choose two.)

• The web server at 192.168.0.10 is reachable from the source host.

• DNS cannot resolve the IP address for the server web-s1.cisco.com.

• A router is down between the source host and the server web-s1.cisco.com.

• There is a problem with the web server software on web-s1.cisco.com.

• The default gateway between the source host and the server at 192.168.0.10 is down.

Answer explanation

Explanation: The successful result of the ping to the IP address indicates that the network is operational and the web server is online. However, the fact that the ping to the domain name of the server fails indicates there is a DNS issue, namely that the host cannot resolve the domain name to its associated IP address.
