- Question
There are three possible routes for a router to reach a destination network. The first route is from OSPF with a metric of 782. The second route is from RIPv2 with a metric of 4. The third is from EIGRP with a composite metric of 20514560. Which route will be installed by the router in its routing table?
Options- A. RIPv2
- B. EIGRP
- C. OSPF
- D. All three
- Correct Answer
- EIGRP
ExplanationOnly 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.
- 1. If your routing table has a static, a RIP, and an EIGRP route to the same network, which route will be used to route packets by default?
Options- A. Any available route
- B. RIP route
- C. Static route
- D. EIGRP route Discuss
- 2. 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 Discuss
- 3. What is the command to copy the startup-config filre to DRAM? Discuss
- 4. You telnet into a remote device and type debug ip rip, but no output from the debug command is seen. What could the problem be?
Options- A. You must type the show ip rip command first
- B. IP addressing on the network is incorrect
- C. You must use the terminal monitor command
- D. Debug output is sent only to the console. Discuss
- 5. You need to subnet a network that has 5 subnets, each wit at least 16 hosts. Which classful subnet mask would you use?
Options- A. 255.255.255.192
- B. 255.255.255.224
- C. 255.255.255.240
- D. 255.255.255.248 Discuss
- 6. What four routed protocols are supported by EIGRP? Discuss
- 7. 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
- D. To manage the VLAN database across multiple switches Discuss
- 8. Which command will configure a switch port to use the IEEE standard method of inserting VLAN membership information into Ethernet frames?
Options- A. Switch (config) #switchport trunk encapsulation ietf
- B. Switch (config) #switchport trunk encapsulation dot1q
- C. Switch (config-if) #switchport trunk encapsulation ietf
- D. Switch (config-if) #switchport trunk encapsulation dot1q Discuss
- 9. You need to stop DoS attacks in real time and have a log of anyone who has tried to attack your network. What should you do your network?
Options- A. Add more routers
- B. Use the auto secure command
- C. Implement IDS/IPS
- D. Configure Naggle Discuss
- 10. How many non- overlapping channels are available with 802.11b?
Options- A. 3
- B. 12
- C. 23
- D. 40 Discuss

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 has a lower administrative distance
Explanation:
RIP 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.
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: 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.
Correct Answer: Implement IDS/IPS
Explanation:
Implementing Intrusion Detection Service and Intrusion prevention Service (IDS/IPS) will help notify you and stop attacks in real time.
Correct Answer: 3
Explanation:
The IEEE 802.11b standard provides three non-overlapping channels.
