- Question
What command do you type to save the configuration stored in RAM to NVRAM?
Options- A. Router(config)#copy current to starting
- B. Router#copy starting to running
- C. Router(config)#copy running-config startup-config
- D. Router#copy run startup
- Correct Answer
- Router#copy run startup
ExplanationTo copy the running-config to NVRAM so that it will be used if the router is restarted, use the copy running-config startup-config command ( copy run start for short). - 1. You configure the following access list:
What will the result of this access list be?access-list 110 deny tcp 10.1.1.128 0.0.0.63 any eq smtp access-list 110 deny tcp any eq 23 int ethernet 0 ip access-group 110 out
Options- A. Email and Telnet will be allowed out E0.
- B. Email and Telnet will be allowed in E0.
- C. Everything but email and Telnet will be allowed out E0.
- D. No IP traffic will be allowed out E0. Discuss
- 2. What is the maximum distance running the lowest data rate for 802.11g?
Options- A. About 100 feet
- B. About 175 feet
- C. About 300 feet
- D. About 350 feet Discuss
- 3. Which of the following is a layer 2 protocol used to maintain a loop-free network?
Options- A. VTP
- B. STP
- C. RIP
- D. CDP Discuss
- 4. What is the maximum data rate for the 802.11g standard?
Options- A. 6Mbps
- B. 11Mbps
- C. 22Mbps
- D. 54Mbps Discuss
- 5. You need to find the broadcast address used on a LAN on your router. What command will you type into the router from user mode to find the broadcast address?
Options- A. show running-config
- B. show startup-config
- C. show interfaces
- D. show protocols Discuss
- 6. Which statement describes a spanning-tree network that has converged?
Options- A. All switch and bridge ports are in the forwarding state.
- B. All switch and bridge ports are assigned as either root or designated ports.
- C. All switch and bridge ports are in either the forwarding or blocking state.
- D. All switch and bridge ports are either blocking or looping. Discuss
- 7. Two connected routers are configured with RIP routing. What will be the result when a router receives a routing update that contains a higher-cost path to a network already in its routing table?
Options- A. The updated information will be added to the existing routing table.
- B. The update will be ignored and no further action will occur.
- C. The updated information will replace the existing routing table entry.
- D. The existing routing table entry will be deleted from the routing table and all routers will exchange routing updates to reach convergence. Discuss
- 8. Which of the following is considered to be the address after translation?
Options- A. Inside local
- B. Outside local
- C. Inside global
- D. Outside global Discuss
- 9. Which switching technology reduces the size of a broadcast domain?
Options- A. ISL
- B. 802.1Q
- C. VLANs
- D. STP Discuss
- 10. Which EIGRP information is held in RAM and maintained through the use of Hello and update packets?
- Neighbor table
- STP table
- Topology table
- DUAL table
Options- A. 2 only
- B. 4 only
- C. 1 and 3
- D. All of the above Discuss
More questions
Correct Answer: No IP traffic will be allowed out E0.
Explanation:
If you add an access list to an interface and you do not have at least one
permit statement, then you will effectively shut down the interface because of the implicit
deny any at the end of every list.
Correct Answer: About 300 feet
Explanation:
The IEEE 802.11g standard's lowest data rate is 6Mbps, but it can run from a distance of about 300 feet.
Correct Answer: STP
Explanation:
The Spanning Tree Protocol is used to stop switching loops in a switched network with redundant paths.
Correct Answer: 54Mbps
Explanation:
The IEEE 802.11g standard provides a maximum data rate of up to 54Mbps.
Correct Answer: show interfaces
Explanation:
The command
show ip protocols will actually show you the broadcast address for each interface - too bad it isn't a possible answer. Your best answer is
show interfaces, which will provide the IP address and mask for each interface.
Correct Answer: All switch and bridge ports are in either the forwarding or blocking state.
Explanation:
Convergence occurs when all ports on bridges and switches have transitioned to either the forwarding or blocking states. No data is forwarded until convergence is complete. Before data can be forwarded again, all devices must be updated.
Correct Answer: The update will be ignored and no further action will occur.
Explanation:
When a routing update is received by a router, the router first checks the administrative distance (AD) and always chooses the route with the lowest AD. However, if two routes are received and they both have the same AD, then the router will choose the one route with the lowest metrics, or in RIP's case, hop count.
Correct Answer: Inside global
Explanation:
The host on the private network after translation is considered to be an inside global host.
Correct Answer: VLANs
Explanation:
Virtual LANs break up broadcast domains in layer 2 switched internetworks.
Correct Answer: 1 and 3
Explanation:
EIGRP holds three tables in RAM: neighbor, topology, and routing. The neighbor and topology tables are built and maintained with the use of Hello packets.
