- Question
A network administrator views the output from the show ip route command. A network that is advertised by both RIP and EIGRP appears in the routing table flagged as an EIGRP route. why is the RIP route to this network not used in the routing table?
Options- A. EIGRP has a faster update timer
- B. EIGRP has a lower administrative distance
- C. RIP has a higher metric for that route
- D. The RIP path has a routing loop
- Correct Answer
- EIGRP has a lower administrative distance
ExplanationRIP has an administrative distance (AD) of 120, while EIGRP has an administrative distance of 90, so the router will discard any route with a higher AD than 90 to that same network.

- 9. What is the purpose of Spanning Tree Protocol in a switched LAN?
Options- A. To provide a mechanism for network monitoring is switched environments
- B. To prevent routing loops in network with redundant paths
- C. To prevent switching loops in networks with redundant switched paths

Correct Answer: copy start run
Correct Answer: You must use the terminal monitor command
Explanation:
To see console messages through your Telnet session, you must enter the terminal monitor command.
Correct Answer: 255.255.255.224
Explanation:
You need 5 subnets, each with at least 16 hosts. The mask 255.255.255.240 provides 16 subnets with 14 hosts - this will not work. The mask 255.255.255.224 provides 8 subnets, each with 30 hosts. This is the best answer.
Correct Answer: 172.16.45.12
Explanation:
A/30, regardless of the class of address, has a 252 in the fourth octet. This means we have a block size of 4 and our subnets are o,4,8,12,16, etc. Address 14 is obviously in the 12 subnet.
Correct Answer: The DoD model is a condensed version of the OSI model, composed of four layers instead of seven, but is nonetheless like the OSI model in that it can be used to describe packet creation and devices and protocols can be mapped to its layers
Correct Answer: Static route
Explanation:
Static routes have an administrative distance of 1 by default. Unless you change this, a static route will always be used over any other dynamically learned route. EIGRP has an administrative distance of 90, and RIP has an administrative distance of 120, by default
Correct Answer: EIGRP
Explanation:
Only the EIGRP routes will be placed in the routing table because it has the lowest administrative distance (AD), and that is always used before metrics.
Correct Answer: The four routed protocols supported by EIGRP are IP, IPv6, IPX, and AppleTalk
Correct Answer: To prevent switching loops in networks with redundant switched paths
Explanation:
The Spanning Tree Protocol (STP) was designed to stop layer 2 loops. All Cisco switches have the STP on by default.
Correct Answer: Switch (config-if) #switchport trunk encapsulation dot1q
Explanation:
If you are on a 2950 switch, then the interface command is just swichport mode trunk since the 2050 can only run the IEEE 802.1q version. However, a 3550 can run both ISL and 802.1q, so you must also use the encapsulation command. The argument to choose 802.1q for a trunking protocol is dot1q.
