Refer to the exhibit. Exhibit 1

Exhibit 2

In exhibit 1, all infrastructure devices are implementing OSPF on the interfaces. Exhibit 1 also shows settings for OSPF areas. Exhibit 2 shows some additional OSPF settings IRF 1.

The network administrator enters this command on IRF 4:

[ IRF4-ospf-1-area-0.0.0.2 ] abr-summary 10.2.0.0 16

The administrator verifies that the solution is functioning correctly. Indicate whether the link state database (LSDB) on a device should include an LSA for 10.2.0.0/16.

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 ACL processes the packet, and the packet is permitted and then switched.

B. The switch routes the packet out of VLAN 4 to the VLAN with the DHCP server.

C. The ACL processes the packet, and the packet is dropped.

D. The switch floods the broadcast in VLAN 4.

A network administrator wants to configure Open Shortest Path (OSPF) MD5 authentication on VLAN 100 on an HP ProVision switch. The administrator has created a global MD5 key chain with an ID and key string that matches the neighbor's. which additional step must the administrator complete to accomplish this?

A. Set OSPF authentication to MD5 mode in the OSPF area settings

B. Activate MD5 key rotation globally

C. Enable MD5 key rotation globally

D. Assign this MD5 key to OSPF VLAN 100

Four HP 3800 Series Switches have formed a backplane stack in a ring topology. Member 1 is the commander the two stacking links on the member 1 fail. What happens?

A. If LACP Multi-Active Detection (MAD) is enabled and the stack connects to a ProVision switch on a link aggregation, member 2, 3 and 4 and shutdown the ports Otherwise, no ports are disabled

B. If LACP Multi-Active Detection (MAD) is enabled member 1 shuts down all of its ports. Otherwise, no ports are disabled

C. If the split policy is one-fragment-up member 1 shuts down all of its ports

D. If the switch policy is one-fragment-up members 2, 3, and 4 shut down all of their ports

Refer to the exhibit.

A company has a functional multicast routing solution, which routes multicasts from the data center users in VLAN3 and VLAN4. Users in VLAN 3 and VLAN 4 sometimes register for some of the same multicast. The network administrator wants to prevent duplicate multicasts on the link between the core IRF virtual switch and the access layer IRF virtual switches.

What should the administrator do to accomplish this goal?

A. Enable IGMP snooping on VLAN 3 and VLAN4 (Layer 2) on the core switch and on the access layer switches.

B. Create Layer 3 interfaces for VLAN 3 and VLAN 4 on the access layer switches, and enable IGMP on the interfaces.

C. Enable Multicast VLAN and IGMP snooping on VLAN 3 on the access layer switches, and associate VLAN 4 as a sub-VLAN.

D. Create Layer 3 interfaces for VLAN 3 and VLAN 4 on the access layer switches, and enable PIM on the interfaces.

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.

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.

Refer to the exhibit. .

A network administrator has begun configuring a Protocol Independent Multicast Sparse Mode (PIM-SM) solution on all of the network infrastructure devices shown in the exhibit. The administrator has selected the static method for configuring rendezvous (RPs) and wants to use 4 as RP.

Where must the administrator configure the static RP setting?

A. On IRF 3 and IRF 4 only

B. On switch 1, IRF 2, IRF 3, and IRF 4

C. On IRF 2, IRF 3, and IRF 4 only

D. On IRF 2 and IRF 3 only

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.
