- 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. What type of RJ45 UTP cable is used between switches?
Options- A. Straight-through
- B. Crossover cable
- C. Crossover with a CSU/DSU
- D. Crossover with a router in between the two switches Discuss
- 2. Using the illustration from the previous question, what would be the IP address of S0 if you were using the first subnet? The network ID is 192.168.10.0/28 and you need to use the last available IP address in the range. Again, the zero subnet should not be considered valid for this question.
Options- A. 192.168.10.24
- B. 192.168.10.62
- C. 192.168.10.30

- Conserves legally registered addresses.
- Causes loss of end-to-end IP traceability.
- Increases flexibility when connecting to the Internet.

Correct Answer: Crossover cable
Explanation:
To connect two switches together, you would use a RJ45 UTP crossover cable.
Correct Answer: 192.168.10.30
Explanation:
A /28 is a 255.255.255.240 mask. The first subnet is 16 (remember that the question stated not to use subnet zero) and the next subnet is 32, so our broadcast address is 31. This makes our host range 17-30. 30 is the last valid host.
Correct Answer: 1 and 2
Explanation:
DR and BDR are elected on broadcast and non-broadcast multi-access networks. Frame Relay is a non-broadcast multi-access (NBMA) network by default. No DR is assigned on any type of point-to-point link. No DR/BDR is assigned on the NBMA point-to-multipoint due to the hub/spoke topology.
Correct Answer: Data, segment, packet, frame, bit
Explanation:
The encapsulation method is data, segment, packet, frame, bit.
Correct Answer: The wildcard mask is incorrect.
Explanation:
The administrator typed in the wrong wildcard mask configuration. The wildcard should have been 0.0.0.255.
Correct Answer: 1, 3 and 5
Explanation:
NAT is not perfect and can cause some issues in some networks, but most networks work just fine. NAT can cause delays and troubleshooting problems, and some applications just won't work.
Correct Answer: show ip nat statistics
Explanation:
The
show ip nat statistics command displays a summary of the NAT configuration as well as counts of active translation types, hits to an existing mapping, misses (causing an attempt to create a mapping), and expired translations.
Correct Answer: clear ip nat translations *
Explanation:
The command
clear ip nat translations * will clear all the active NAT entries in your translation table.
Correct Answer: ip nat inside
Explanation:
As in access-lists, you must configure your interfaces before NAT will provide any translations. On the inside networks you would use the command
ip nat inside. On the outside interface, you will use the command
ip nat outside.
Correct Answer: 1, 3 and 5
Explanation:
You can configure NAT three ways on a Cisco router: static, dynamic, and NAT Overload (PAT).
