1. An engineer must configure a /30 subnet between two routers. Which usable IP address and subnet mask combination meets this criteria?

interface e0/0
description to HQ-A371:10975
ip address 172.16.1.4 255.255.255.248

interface e0/0
description to HQ-A371:10975
ip address 192.168.1.1 255.255.255.248

interface e0/0
description to HQ-A371:10975
ip address 209.165.201.2 255.255.255.252

interface e0/0
description to HQ-A371:10975
ip address 10.2.1.3 255.255.255.252

Question 1 of 9

2. An office has 8 floors with approximately 30-40 users per floor. What command must be configured on the router Switched Virtual Interface to use address space efficiently?

ip address 192.168.0.0 255.255.254.0

ip address 192.168.0.0 255.255.0.0

ip address 192.168.0.0 255.255.255.128

ip address 192.168.0.0 255.255.255.224

3. Refer to the exhibit. A network technician is asked to design a small network with redundancy. The exhibit represents this design, with all hosts configured in the same VLAN. What conclusions can be made about this design?

The design will function as intended

Spanning-tree will need to be used.

The router will not accept the addressing scheme.

The connection between switches should be a trunk.

The router interfaces must be encapsulated with the 802.1Q protocol.

4. Refer to exhibit. Which statement explains the configuration error message that is received?

Router(config)#interface GigabitEthernet 1/0/1
Router(config-if)#ip address 192.168.16.143 255.255.255.240
Bad mask /28 for address 192.168.16.143

It belongs to a private IP address range

It is a network IP address

It is a broadcast IP address

The router does not support /28 mask

5. Which goal is achieved by the implementation of private IPv4 addressing on a network?

provides a reduction in size of the forwarding table on network routers

provides an added level of protection against Internet exposure

allows servers and workstations to communicate across public network boundaries

allows communication across the Internet to other private networks

6. A corporate office uses four floors in a building
* Floor 1 has 24 users
* Floor 2 has 29 users
* Floor 3 has 28 users
* Floor 4 has 22 users

Which subnet summarizes and gives the most efficient distribution of IP addresses for the router configuration?

192.168.0.0/25 as summary and 192.168.0.0/27 for each floor

192.168.0.0/24 as summary and 192.168.0.0/28 for each floor

192.168.0.0/23 as summary and 192.168.0.0/25 for each floor

192.168.0.0/26 as summary and 192.168.0.0/29 for each floor

7. Refer to the exhibit. An engineer must add a subnet for a new office that will add 20 users to the network. Which IPv4 network and subnet mask combination does the engineer assign to minimize wasting addresses?

10.10.225.48 255.255.255.240

10.10.225.32 255.255.255.240

10.10.225.32 255.255.255.224

8. Which network allows devices to communicate without the need to access the Internet?

172.28.0.0/16

172.9.0.0/16

209.165.201.0/24

192.0.0.0/8

Question 8 of 9

9. Which function does the range of private IPv4 addresses perform?

Denables secure communications to the internet for all external hosts

ensures that NAT is not required to reach the internet with private range addressing

allows multiple companies to each use the same addresses without conflicts

provides a direct connection for hosts from outside of the enterprise network
