  OSPF router R2 has both point-to-point and broadcast interfaces and it is not a DR for any interfaces. Router R2 detects the link failure between itself and router R1. Which of the following is correct?

  A. Router R2 sends an update to 224.0.0.5 on its broadcast and point-to-point interfaces. The DR does not send any updates.
  B. Router R2 sends an update to 244.0.0.5 on its point-to-point interfaces. The DR sends an update to 224.0.0.6 on the broadcast network.
  C. Router R2 sends an update to 224.0.0.5 out its point-to-point interfaces and an update to 224.0.0.6 out its broadcast interface. The DR sends updates to 224.0.0.5 on the broadcast network.
  D. Router R2 sends an update to 224.0.0.6 out its point-to-point interfaces and an update to 224.0.0.5 out its broadcast interface. The DR sends an update to 224.0.0.6 on the broadcast networks.
  C. Router R2 sends an update to 224.0.0.5 out its point-to-point interfaces and an update to 224.0.0.6 out its broadcast interface. The DR sends updates to 224.0.0.5 on the broadcast network.

• Question 379:

• Question 380:

  An LSP path is configured as follows:

  -Shared-explicit reservation style

  -Make-before-break (MBB) enabled

  -

  500Mpbs bandwidth reserved on a 1Gbps link

  With 100Mbps of unreserved bandwidth remaining, the operator increases the LSP-path's bandwidth reservation to 900Mbps. What happens to the existing LSP?

  A. CSPF looks for the delta bandwidth, taking down the first path if necessary.
  B. CSPF looks for the delta bandwidth, implementing make-before-break.
  C. After 5 failed attempts to find the bandwidth requested, the head end disables the LSP.
  D. CSPF looks for the entire bandwidth requested, implementing MBB.
  B. CSPF looks for the delta bandwidth, implementing make-before-break.
