The network administrator requires easy configuration options and minimal routing protocol traffic. What two options provide adequate routing table information for traffic that passes between the two routers and satisfy the requests of the network administrator? (Choose two.)

  1. a dynamic routing protocol on InternetRouter to advertise all routes to CentralRouter.

  2. a dynamic routing protocol on InternetRouter to advertise summarized routes to CentralRouter.

  3. a static route on InternetRouter to direct traffic that is destined for 172.16.0.0/16 to CentralRouter.

  4. a dynamic routing protocol on CentralRouter to advertise all routes to InternetRouter.

  5. a dynamic routing protocol on CentralRouter to advertise summarized routes to InternetRouter.

  6. a static, default route on CentralRouter that directs traffic to InternetRouter.

Answer: C,F Explanation:

The use of static routes will provide the necessary information for connectivity while producing no routing traffic overhead.

Which address and mask combination represents a summary of the routes learned by EIGRP?

A. 192.168.25.0 255.255.255.240

B. 192.168.25.0 255.255.255.252

C. 192.168.25.16 255.255.255.240

D. 192.168.25.16 255.255.255.252

E. 192.168.25.28 255.255.255.240

F. 192.168.25.28 255.255.255.252

Answer: C Explanation:

The binary version of 20 is 10100. The binary version of 16 is 10000. The binary version of 24 is 11000. The binary version of 28 is 11100.

The subnet mask is /28. The mask is 255.255.255.240.

Note:

From the output above, EIGRP learned 4 routes and we need to find out the summary of them:

192.168.25.16

192.168.25.20

192.168.25.24

192.168.25.28

-gt; The increment should bE. 28 – 16 = 12 but 12 is not an exponentiation of 2 so we must

choose 16 (24). Therefore the subnet mask is /28 (=1111 1111.1111 1111.1111

1111.11110000) = 255.255.255.240.

So, the best answer should be 192.168.25.16 255.255.255.240.

Question No: 103 DRAG DROP – (Topic 3)

Routing has been configured on the local router with these commands: Local(config)# ip route 0.0.0.0 0.0.0.0 192.168.1.1

Local(config)# ip route 10.1.0.0 255.255.255.0 192.168.2.2

Local(config)# ip route 10.1.0.0 255.255.0.0 192.168.3.3

Drag each destination IP address on the left to its correct next hop address on the right.

Explanation:

If we have many entries matching for next hop ip address then the router will choose the one with most specific path to send the packet. This is called the “longest match” rule, the route with the most bits in the mask set to “1 will be chosen to route packet.

Question No: 104 – (Topic 3)

Before installing a new, upgraded version of the IOS, what should be checked on the router, and which command should be used to gather this information? (Choose two.)

  1. the amount of available ROM

  2. the amount of available flash and RAM memory

  3. the version of the bootstrap software present on the router

  4. show version

  5. show processes

  6. show running-config

Answer: B,D Explanation:

When upgrading a new version of the IOS we need to copy the IOS to the Flash so first we have to check if the Flash has enough memory or not. Also running the new IOS may require more RAM than the older one so we should check the available RAM too. We can check both with the “show version” command.

Question No: 105 – (Topic 3)

What is the default maximum number of equal-cost paths that can be placed into the routing table of a Cisco OSPF router?

  1. 2

  2. 8

  3. 16

  4. unlimited

Answer: B Explanation:

maximum-paths (OSPF)

To control the maximum number of parallel routes that Open Shortest Path First (OSPF) can support, use the maximum-paths command.

Syntax Description

maximum

Maximum number of parallel routes that OSPF can install in a routing table. The range is from 1 to 16 routes.

Command Default

8 paths

Question No: 106 – (Topic 3)

Which three elements must be used when you configure a router interface for VLAN trunking? (Choose three.)

  1. one physical interface for each subinterface

  2. one IP network or subnetwork for each subinterface

  3. a management domain for each subinterface

  4. subinterface encapsulation identifiers that match VLAN tags

  5. one subinterface per VLAN

  6. subinterface numbering that matches VLAN tags

Answer: B,D,E Explanation:

This scenario is commonly called a router on a stick. A short, well written article on this operation can be found here: http://www.thebryantadvantage.com/RouterOnAStickCCNACertificationExamTutorial.htm

Question No: 107 – (Topic 3)

Which command shows your active Telnet connections?

  1. show cdp neigbors

  2. show session

  3. show users

  4. show vty logins

Answer: B Explanation:

The “show users” shows telnet/ssh connections to your router while “show sessions” shows telnet/ssh connections from your router (to other devices). The question asks about “your active Telnet connections”, meaning connections from your router so the answer should be A.

Question No: 108 – (Topic 3)

What are two enhancements that OSPFv3 supports over OSPFv2? (Choose two.)

  1. It requires the use of ARP.

  2. It can support multiple IPv6 subnets on a single link.

  3. It supports up to 2 instances of OSPFv3 over a common link.

  4. It routes over links rather than over networks.

Answer: B,D

Question No: 109 – (Topic 3)

Refer to the exhibit.

Given the output for this command, if the router ID has not been manually set, what router ID will OSPF use for this router?

A. 10.1.1.2

B. 10.154.154.1

C. 172.16.5.1

D. 192.168.5.3

Answer: C Explanation:

The highest IP address of all loopback interfaces will be chosen -gt; Loopback 0 will be chosen as the router ID.

Question No: 110 – (Topic 3)

Which two locations can be configured as a source for the IOS image in the boot system command? (Choose two.)

  1. RAM

  2. NVRAM

  3. flash memory

  4. HTTP server

  5. TFTP server

  6. Telnet server

Answer: C,E Explanation:

The following locations can be configured as a source for the IOS image:

1. Flash (the default location)

2. TFTP server

3. ROM (used if no other source is found)

  1. (Please read the explanation of Question 4 for more information)
