| Question ID 14530 | Why do large OSPF networks use a hierarchical design? (Choose three.)
|
| Option A | to decrease latency by increasing bandwidth
|
| Option B | to reduce routing overhead
|
| Option C | to speed up convergence
|
| Option D | to confine network instability to single areas of the network
|
| Option E | to reduce the complexity of router configuration
|
| Option F | to lower costs by replacing routers with distribution layer switches
|
| Correct Answer | B,C,D |
Explanation Explanation: OSPF implements a two-tier hierarchical routing model that uses a core or backbone tier known as area zero (0). Attached to that backbone via area border routers (ABRs) are a number of secondary tier areas. The hierarchical approach is used to achieve the following: ✑ Rapid convergence because of link and/or switch failures ✑ Deterministic traffic recovery ✑ Scalable and manageable routing hierarchy, reduced routing overhead.
| Question ID 14531 | Which two commands will display the current IP address and basic Layer 1 and 2 status of
an interface? (Choose two.)
|
| Option A | router#show version
|
| Option B | router#show ip interface
|
| Option C | router#show protocols
|
| Option D | router#show controllers
|
| Option E | router#show running-config
|
| Correct Answer | B,C |
Explanation Explanation: The outputs of show protocols and show ip interface are shown below: Global values:Internet Protocol routing is enabledSerial0/0 is up, line protocol is downInternet address is 10.1.1.1/30Serial0/1 is up, line protocol is downInternet address is 209.65.200.225/30Serial0/2 is up, line protocol is downSerial0/3 is up, line protocol is downNVI0 is up, line protocol is upInterface is unnumbered.
