• Question 52:

  Refer to the exhibit. Exhibit 1

  

  Exhibit 2

  

  In exhibit 1, all infrastructure devices are implementing OSPF on the interfaces. Exhibit 1 also shows settings for OSPF areas. Exhibit 2 shows some additional OSPF settings IRF 1.

  The network administrator enters this command on IRF 4:

  [ IRF4-ospf-1-area-0.0.0.2 ] abr-summary 10.2.0.0 16

  The administrator verifies that the solution is functioning correctly. Indicate whether the link state database (LSDB) on a device should include an LSA for 10.2.0.0/16.

• Question 54:

  Refer to the exhibit.

  

  Switch 3 runs Rapid Per-VLAN Spanning Tree Plus (RPVST+), which is enabled on VLANs 1-4. Select the correct number for each of these parameters.

  Correct Answer:

  

  Rapid PVST+ is the IEEE 802.1w (RSTP) standard implemented per VLAN. A single instance of STP runs on each configured VLAN (if you do not manually disable STP). Each Rapid PVST+ instance on a VLAN has a single root switch. You

  can enable and disable STP on a per-

  VLAN basis when you are running Rapid PVST+.

  When a switch transmits a Rapid PVST+ BPDU frame, all switches connected to the VLAN on which the frame is transmitted receive the BPDU. When a switch receives a BPDU, it does not forward the frame but instead uses the information

  in the frame to calculate a BPDU,

  and, if the topology changes, initiate a BPDU transmission.

  A BPDU exchange results in the following:

  One switch is elected as the root bridge.

  The shortest distance to the root bridge is calculated for each switch based on the path cost.

  A designated bridge for each LAN segment is selected. This is the switch closest to the root bridge through which frames are forwarded to the root.

  A root port is selected. This is the port providing the best path from the bridge to the root bridge.

  Ports included in the spanning tree are selected.

  See the "Rapid PVST+ BPDUs" section for a information about the fields that Rapid PVST+ adds to the BPDU.
