• Question 11:

  A network administrator is completing an In-Service Software Upgrade (ISSU) for an Intelligent Resilient Framework (IRF) virtual devices. The device has two members.

• Question 12:

  A company wants to enforce source-specific multicasting (SSM) for several multicast streams. This is the configuration:

  Some multicast receivers support IGMPv3.

  Other receivers that need to stream support IGMPv2 only.

  The multicast receivers' default routers enable IGMPv3 on the interfaces associated with their subnets. The routers are correctly configured to enable the IGMPv3 receivers to receive the stream from the correct source Which setting do the receivers' routers require to support the IGMPV2 devices?

  A. An SSM policy that selects the IGMPv2 devices and binds them to an RP address
  B. An SSM map that sets a rendezvous point (RP) for each multicast address
  C. An SSM policy that selects the appropriate multicast destinations and binds them to an RP address
  D. An SSM map that sets the correct source for each multicast address
  D. An SSM map that sets the correct source for each multicast address

• Question 13:

  A network administrator is configuring several HP Comware switches as an HP Intelligent Resilient Framework (IRF) virtual device. According to best practices at, which point during the IRF configuration process should the administrator activate the IRF ports?

  A. After enabling the physical interfaces that are assigned to IRF ports and saving the settings
  B. After configuring IRF ports but before assigning physical interfaces to them
  C. After enabling the physical interfaces that are assigned to IRF ports but before saving the settings
  D. Before configuring IRF ports or assigning physical interfaces to them
  A. After enabling the physical interfaces that are assigned to IRF ports and saving the settings

• Question 14:

  Refer to the exhibit.

  

  A company wants to implement a portal authentication solution for guests (such a solution is also called Web-Auth). Guest belong to VLAN4, as shown in the exhibit. The intelligent Management Center (IMC) User Access Manager (UAM) will provide authentication and the Web Portal.

  Where should the network administrator enable portal authentication?

  A. On the VLAN 4 interface on the core IRF virtual switch
  B. On the ports with membership for VLAN 4 on the access layer IRF virtual switches
  C. On the ports with membership for VLAN 4 on the core IRF virtual switch
  D. On VLAN 4 on the core IRF virtual switch
  B. On the ports with membership for VLAN 4 on the access layer IRF virtual switches

• Question 15:

  Refer to the exhibit.

  

  The current software on the Intelligent Resilient Framework (IRF) virtual device shown in the exhibit is version 1104. The network administrator wants to upgrade to software version 1105. What will happen when the administrator attempts to use In-Service Software Upgrade (ISSU) for this upgrade?

  A. The IRF virtual device will not accept the ISSU commands. It will output various error messages.
  B. When the administrator executes the switch over to the new master, a rollback will occur, causing the software to revert to the previous version.
  C. The process can complete successfully. Some links might go down, causing temporary failovers within link aggregation groups.
  D. When the administrator executes the switchover to the new master, an outage will occur while this master reboots.
  C. The process can complete successfully. Some links might go down, causing temporary failovers within link aggregation groups.

• Question 16:

  Two HP 10500 Series Switches connect on a 10G fiber link. One of the two fibers in the link breaks, and a broadcast storm occurs. How could a network administrator prevent a problem like this from happening again?

  A. Configure Device Link Detection Protocol (DLDP) on both sides of the link.
  B. Use Rapid Per VLAN Spanning Tree Plus (RPVST+) instead of Multiple Spanning Tree Protocol (MSTP).
  C. Implement sFlow or NetStream on both sides of the link, setting the collector to an Intelligent Management Center (IMC) server.
  D. Add another 10G link and create a link aggregation group on each switch that includes both links.
  A. Configure Device Link Detection Protocol (DLDP) on both sides of the link.

• Question 17:

  Refer to the exhibits. Exhibit 1

  

  Exhibit 2

  

  Exhibit 2 shows the Virtual Router Redundancy Protocol (VRRP) configuration and status for VLAN 3 on switch 1 during normal operation, when both Switch 1 and Switch 2 are up. Switch 1 then experiences a power failure. After a few

  minutes, power is restored, and the switch comes back up.

  What happens to VRRP operations in VLAN 3?

  A. Switch 1 becomes Master two minutes after its VRRP processes up.
  B. Switch 2 remains Master Switch 1 receives an error and stops participating in VRRP
  C. Switch 2 remains Master, and Switch 1 becomes a Backup router.
  D. Switch 1 becomes Master as soon as its VRRP processes come up.
  C. Switch 2 remains Master, and Switch 1 becomes a Backup router.

• Question 18:

  Refer to the exhibit. Exhibit 1

  

  Exhibit 2

  

  Client 1 is transmitting traffic to the data center. Switch 3 transmits the traffic on the link to Switch 1. How does Switch 1 handle the traffic received from Client 1?

  A. It forwards the traffic over the ISC to Switch 2.
  B. It routes the traffic and forwards it towards the data center.
  C. It drops the traffic.
  D. It forwards the traffic over the keepalive link to Switch 2.
  A. It forwards the traffic over the ISC to Switch 2.

• Question 19:
