Online Access Free HP0-Y47 Practice Test

Refer to the exhibit.

The switch with the ACL shown in the exhibit has IP address 10.1.4/24 on VLAN 4. It is the default router for 10.1.0/24. A client in VLAN 4 broadcast a DHCP discovery request, and the request arrives on this switch.
What happens?

• A.The switch floods the broadcast in VLAN 4.
• B.The ACL processes the packet, and the packet is permitted and then switched.
• C.The ACL processes the packet, and the packet is dropped.
• D.The switch routes the packet out of VLAN 4 to the VLAN with the DHCP server.

HOTSPOT
Match the characteristic to the routing protocol.

Correct Answer:

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

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

Refer to the exhibit.

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