Question #11 (Topic: )
Refer to the exhibit.
Exhibit 1
[HP-HP0-Y47-7.0/HP-HP0-Y47-12_2.png]
Exhibit 2
[HP-HP0-Y47-7.0/HP-HP0-Y47-12_3.png]
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?

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.
Answer: D
Question #12 (Topic: )
Refer to the exhibit.
[HP-HP0-Y47-7.0/HP-HP0-Y47-13_2.png]
IRF 3 and Switches 1, 2 and 4 are successfully implementing OSPF on the interfaces
shown in the exhibit. Then IRF 3s 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?

IRF 3 and Switches 1, 2 and 4 are successfully implementing OSPF on the interfaces
shown in the exhibit. Then IRF 3s 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. Enable opaque LSAs on each of the switches; set the OSPF graceful restart mode to IETF mode on at least IRF 3.
B. Set the OSPF dead timer on each of the switches to equal the hello timer
C. Set up OSPF Bidirectional Forwarding Detection (BFD) on each switch VLAN 10 interface.
D. On IRF 3, set up Bidirectional Forwarding Detection (BFD) Multi-Active Detection (MAD) on a dedicated link between the members.
Answer: A
Question #13 (Topic: )
Refer to the exhibit.
[HP-HP0-Y47-7.0/HP-HP0-Y47-15_2.png]
The five routers shown in the exhibit are successfully implementing OSPF on the interface
shown in the exhibit. The exhibit also shows settings for OSPF areas and interface costs.
A network administrator enters these commands on Router 4 and Router 5:
[HP-HP0-Y47-7.0/HP-HP0-Y47-15_3.png]
How can the administrator ensures that Router 2 learns the route to 172.16.0.0/16 with
next hop 10.0.0.6?

How can the administrator ensures that Router 2 learns the route to 172.16.0.0/16 with
next hop 10.0.0.6?
A. On Router 2, enables OSPF ECMP globally
B. On Router 4 and 5, change the metric type for redistributed static routes to type 1
C. On Router 4, change the cost for redistributed static routes to 2
D. On Router 2, 3, 4 and 5, change the bandwidth reference value to 100
Answer: B
Question #14 (Topic: )
Refer to the exhibit.
[HP-HP0-Y47-7.0/HP-HP0-Y47-16_2.png]
A network administrator up a remote mirroring on the HP Comware switches in the exhibit.
The administrator must define several port while entering mirroring-group commands on
these switches. Which port should be the reflector port (sometimes called monitor-egress
port)?

A. Switch 1, G1/0/2
B. Switch3, T1/0/4
C. Switch 1, T1/0/25

Answer: B
Question #15 (Topic: )
Refer to the exhibit.
[HP-HP0-Y47-7.0/HP-HP0-Y47-17_2.png]
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?

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 2s 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
Answer: D
