  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.

  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:

• Question 23:

  What distinguishes an HP switch with a CLOS fabric from an HP switch with a crossbar fabric?

  A. The CLOS fabric can integrate with a virtual switch, which is deployed in a virtualized server.
  B. The CLOS fabric is a requirement for an Intelligent Resilient Framework (IRF) virtual switch with more than two members.
  C. The CLOS fabric can dynamically shut down power to unused switch ports, proving better energy efficiency.
  D. The CLOS fabric can dynamically load-balance internal traffic over many paths, helping the switch support 40G/100G.
  D. The CLOS fabric can dynamically load-balance internal traffic over many paths, helping the switch support 40G/100G.

• Question 24:

  Refer to the exhibit.

  

  IRF 1, at the campus core campus core, enables Internet Group Management Protocol (IGMP) on its VLAN3 interface. IRF 1 is also part of a multicast routing solution with the data center infrastructure devices. How can a network administrator ensure that only endpoints that have registered for multicasts destined to 239.1.1.1 receive these multicasts?

  A. On every campus IRF virtual switch, set VLAN 3 as the multicast VLAN
  B. On IRF 1, enable IGMP snooping on VLAN3
  C. On each access layer IRF virtual switch, enable IGMP snooping on VLAN 3
  D. On each access layer IRF virtual switch, create a Layer 3 interface VLAN3. Enable IGMP on that interface
  C. On each access layer IRF virtual switch, enable IGMP snooping on VLAN 3

• Question 25:

• Question 26:

  An HP switch is a member of an Intelligent Resilient Framework (IRF) virtual device that has two members. What is a proper situation for issuing the mad restore command on this switch?

  A. The IRF link has failed, and MAD has caused a new member to become master. The administrator wants to restore the previous master's MAC address.
  B. The IRF link has failed, and MAD placed this member in recovery mode. The administrator wants the switch to automatically repair the failed link.
  C. The IRF link has failed, and the administrator needs to put this switch in MAD recovery mode.
  D. The IRF link has failed, and MAD placed this member in recovery mode. The active member has gone offline.
  B. The IRF link has failed, and MAD placed this member in recovery mode. The administrator wants the switch to automatically repair the failed link.

• Question 27:

  HP Comware Switch 1 connects to switch 2 on GigabitEthernet 1/0/1. Swutch 2 implements an inbound rate limit of 600 Mbps. The network administrator wants switch 1 to buffer traffic that exceeds the Switch 2 rate limit of 600 Mbps and send the traffic at 600 Mbps. All traffic has the same 802.1p priority and is forwarded in priority queue 2. What should the administrator apply to the Switch 1 interface GigabitEthernet 1/0/1?

  A. A line rate limit of 600 Mbps on queue 2
  B. A QoS policy with a classifier that matches all traffic and a CAR behavior that sets a CIR of 600 Mbps
  C. A weighted random early discard (WRED) table with a limit of 600 for queue 2
  D. A traffic shaping rate limit of 600 Mbps on queue 2
  D. A traffic shaping rate limit of 600 Mbps on queue 2

• Question 28:

  Refer to the exhibit.

  

  Switch 1 and switch 2 run open Shortest Path First (OSPF) on all VLANs. Both switches establish an OSPF adjacency to a router at the main data center. Exhibit shows shoes some virtual Routing Redundancy Protocol (VRRP) and OSPF settings on Switch 1 during normal operation.

  How can a network administrator increase the resiliency of this solution?

  A. Implement Bidirectional Forwarding Detection (BFD) on the peer keep alive link between the core switches.
  B. Change the VLAN 10 subnet to a /24 subnet and enable VRRP on it. Place Switch 2's link to the main data center in this subnet.
  C. Make sure that, in each VRRP instance, each switch has a VRRP preempt delay of several minutes.
  D. Configure Switch 1 as an OSPF graceful restart helper in VLAN 11 and Switch 2 as a helper in VLAN 10
  D. Configure Switch 1 as an OSPF graceful restart helper in VLAN 11 and Switch 2 as a helper in VLAN 10

• Question 29:

  Refer to the exhibit.

  

  The HP 3800 switch with member ID 1 shown in the exhibit goes down. What happens?

  A. Switch 2 becomes the commander
  B. Switch 2 becomes the commander
  C. Switch 4 becomes the commander
  D. The switch that has the longest uptime becomes master
  B. Switch 2 becomes the commander

• Question 30:

  Refer to the exhibit. Exhibit 1

  

  Exhibit 2

  

  Exhibit 1 shows a simplified network topology. All infrastructure devices shown in the exhibit are successfully implementing (OSPF) on the interfaces. The exhibit also shows settings for OSPF areas. Exhibit 2 shows additional settings on IRF. The master within IRF 1 fails. Connectivity is disrupted for about one minute.

  What can the network administrator do to prevent this issue occurring again?

  A. Set up OSPF Bidirectional Forwarding Detection (BFD) on the routed link aggregation groups between the IRF virtual switches
  B. Enable extended Link Access Control Detection Data Units (LACPDUs) on IRF 1 and IRF 4
  C. On IRF 1, set up Bidirectional Forwarding Detection (BFD) Multi-Access Detection (MAD) with a dedicated link.
  D. On each of the IRF virtual switches, enable opaque LSAs and set the OSPF graceful restart mode to IETF mode.
  D. On each of the IRF virtual switches, enable opaque LSAs and set the OSPF graceful restart mode to IETF mode.
