CCNA Practice Quiz: 200-301 Quiz 14

1. Routing data between computers on a network requires several mappings between different addresses. Which of the following statements is true?

• Diskless workstations use ARP to ask a server for an IP address.
• Routers use DNS to resolve MAC addresses of diskless workstations into IP addresses based on the information contained in other routers' route tables.
• Routers use ARP to resolve known IP addresses into MAC addresses.
• ICMP lets routers bypass the general network broadcast by providing a dynamic table of IP-to-MAC address mappings.

2. You have issued the following command and received the response as shown.

Router#sh start
%%Non-volatile configuration memory has not been set up or has bad checksum

Which of the following is a reason for this response?

• RAM memory contains no configuration file.
• The command was issued from user EXEC mode but needs to be issued from privileged EXEC mode instead.
• No configuration file has been saved to NVRAM.
• The router issues a bad checksum because a file on the TFTP server is also named startup-config.

3. You need to add VoIP and IP telephony support to a router. Which feature set must be enabled to do this?

• Security
• Unified Communication
• IP Base
• Data

4. Which of the following commands configures a password to switch to privileged EXEC mode and saves the password using MD5 hashing?

• password
• service password-encryption
• enable password
• enable secret

5. Which feature implemented with a Distance Vector Routing Protocol reduces the convergence time?

• TTL
• Triggered updates
• Hold down timers
• Poison reverse
• Split horizon

6. Router_1 is connected to three networks, 192.168.0.0, 172.16.16.0, and 172.16.32.0. An administrator enables the RIP routing protocol on Router_1. The router isn't forwarding packets to network 172.16.16.0. The administrator examines the configuration on Router_1 using the sh run command.

What should the administrator do to correct the problem?

• Configure a default route.
• Reconfigure the RIP routing protocol.
• Use the IGRP routing protocol.
• Enable the Serial0 interface.

7. In which type of network must packets being sent between subnets pass through one or more subnets of a different network?

• Classful
• Discontiguous
• OSPF
• Contiguous

8. Which of the following is used to communicate within a site or between a limited number of sites?

• Global unicast addresses
• Link-local addresses
• Unique local unicast addresses
• Subnet addresses

9. On which layer of the OSI model does routing occur?

• Physical
• Application
• Transport
• Network

10. A connection or communication problem on the Data Link Layer could be indicated by which interface status?

• Line Status down and Protocol Status down
• Line Status up and Protocol Status up
• Line Status administratively down and Protocol Status down
• Line Status up and Protocol Status down
