Question

Refer to the exhibit. An enterprise customer reported packet drops to 192.168.1.1 from the hub site. The network operation team found that the link between RC and RA is down in OSPF area 200. Routers RZ, RB, and RC set up OSPF neighborship with all adjacent routers. Which configuration must be applied to router RC to resolve the issue?

Exhibit

300-515 question #100 exhibit

Options

  • ARC(config)#int fastEthernet 1/0
  • BRC(config)#int fastEthernet 1/0
  • CRC(config)#int fastEthernet 1/0
  • DRC(config)#int fastEthernet 1/0

Explanation

The question as provided is incomplete in several ways that make it impossible to answer accurately:

  1. All four choices show identical text - RC(config)#int fastEthernet 1/0 - the distinguishing configuration commands (the lines that follow the interface declaration) are missing or were cut off.
  2. The correct answer is blank - no answer letter was specified.
  3. The exhibit is missing - the network topology referenced by "Refer to the exhibit" is not included.

To give you a useful explanation, please provide:

  • The full configuration commands for each choice (A–D), not just the interface line
  • The correct answer letter
  • The exhibit (network diagram showing the topology, IP addressing, and OSPF area assignments)

Once you share those, I can explain the OSPF concepts involved - likely related to virtual links, area configurations, or passive-interface settings needed to restore the RC↔RA adjacency in Area 200.
