  The link between routers R4 and R6 are configured with an admin group "red". What happens when the LSP is first signaled?

  A. The LSP will go through the path R1-R2-R4-R6.
  B. The LSP will go through the path R1-R3-R5-R6.
  C. The LSP is down because router R1 detects that no path can meet its constraints.
  D. The LSP is down because router R4 detects that no path can meet its constraints.

• Question 170:

  If OSPF is used in a multi-area OSPF network, which of the following statements regarding route summarization is true?

  A. Manual route summarization can only be done on autonomous system border routers.
  B. Manual route summarization must be done on all the backbone routers to be effective. Manual route summarization is optional on the routers in non-backbone areas.
  C. Manual route summarization is done on the ABRs. By default, automatic summarization is done; however, it may not be optimal for all networks.
  D. Manual route summarization is done on the ABRs. By default, no route summarization is done and all routes are advertised to all areas.
  D. Manual route summarization is done on the ABRs. By default, no route summarization is done and all routes are advertised to all areas.
