IRF 3 and Switches 1, 2 and 4 are successfully implementing OSPF on the interfaces shown in the exhibit. Then IRF 3's 10.1.10/24 link fails. Connectivity between Server 1 and Server 2 is disrupted for about 30 seconds.
What can the network administrator do to prevent this issue from occurring again?

• A.Set up OSPF Bidirectional Forwarding Detection (BFD) on each switch VLAN 10 interface.
• B.Set the OSPF dead timer on each of the switches to equal the hello timer
• C.Enable opaque LSAs on each of the switches; set the OSPF graceful restart mode to IETF mode on at least IRF 3.
• D.On IRF 3, set up Bidirectional Forwarding Detection (BFD) Multi-Active Detection (MAD) on a dedicated link between the members.

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

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

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

These three routers are currently configured for BGP. They do not apply any routing policy in terms of BGP on routes or attributes advertised to an received from peers. How can the network administrator for Router 1 cause Router 1 to advertise 192.0.2.0/24 to Router 2
and Router 3?

• A.Add a null route to 192.0.2.0/24
• B.Enable BGP routing on RAGG1
• C.Apply route policy 1 as an outbound policy for both peers
• D.Apply route policy 1 as an inbound policy for both peers

Refer to the exhibit.

Switch 1 and Switch 2 have established and Interswitch Connection (ISC) and two distributed trunks. All of the switches have Multiple Spanning tree Protocol (MSTP) enabled. Where does Switch 1 transmit or process Bridge Protocol Data Units (BPDUs)?

• A.On trk1, trk2, trk3
• B.On trk1 and trk3
• C.On trk2
• D.On trk2 and the peer keepalive
