Given the CIDR address range of 200.165.160.0 to 200.165.191.255, what is the CIDR
block?

Given these four Class B networks: 172.104.0.0, 172.105.0.0, 172.106.0.0, 172.107.0.0,
what is the supernet (CIDR) address that summarizes these four Class B networks?

This show output is from the S7 Cisco Metro Switch and the PE7 Cisco ASR 9000 Series
Router. Which configuration change(s) is/are needed to bring the S7 FastEthernet 0/2
interface into the up/up state?

What does a transparent LAN switch use to build its CAM table?

You are having problems browsing to http://www.cisco.com from your laptop that is running
Windows. Your laptop is connected directly to a default gateway, which is a Cisco ISR G2
router. Which four options are the basic troubleshooting steps that you should use to
troubleshoot this issue? (Choose four.)

Refer to the exhibit.

You want to enable these three actions:
• Enable the fa0/1 router’s interface to obtain its interface IP address dynamically from a
DHCP server.
• Enable the router to configure the next hop ip address of the default route automatically
based on the DHCP response.

• Enable the router to act as the DHCP server for other clients connected to the router fa0/2
interface.
Which three Cisco IOS configurations must you use? (Choose three.)

You need to enable the “local-router” serial 0/0 connection to the “remote-router” to be
authenticated using the “C!sco!23” password. The password cannot be sent in cleartext
between the two routers. The “remote-router” has already been configured with all the
required configurations.
Which four Cisco IOS configurations are necessary? (Choose four.)

Which two statements about Cisco IOS XE operations are true? (Choose two.)

Refer to the exhibit.

Using a single Class C network of 192.168.1.0/24 and VLSM, which two options specify the
number of subnets that are needed to support this network and what are the minimum sizes
of the required subnets? (Choose two.)

Which option is enabled by default on Cisco IOS and IOS XE routers?
