1. Click the Exhibit button and view a network diagram and two switch configurations.

Network 16.2.0.0 /16 is advertised by Router 1 and Router 2 into BGP. All traffic from AS-65002 destined to 16.2.0.0 /16 enters AS 65001 via the Serial 3 interface of Router 1.

The administrator prefers that this traffic enter AS 65001 via interface Serial 4 of Router 2.Which configuration change is most likely to achieve the desired results?

A) Router-1#route-policy PolicyA permit node 20 if-match ip-prefix Prefix2 apply cost 6000routepolicy PolicyA permit node 100Router-2#route-policy PolicyA permit node 20 if-match ip-prefix Prefix2 apply cost 7000route-policy PolicyA permit node 100

You are planning to replace Cisco distribution layer switches with HP A-Series switches, and you are selecting a general strategy for the migration process. The strategy you select is to connect the new switches in parallel to the existing network. You will move the edge switch connections to the new distribution switches during the migration, as shown in the exhibit What is a disadvantage of this strategy?

A) This approach requires you to shut down the network for at least several hours, because of the network size.
B) You must migrate the routing functionality for every VLAN simultaneously, so you cannot assess how the migration is working for a single VLAN before completing the migration.
C) The connection between the existing distribution switches and the parallel network might become a bottleneck during the migration process unless you plan sufficient bandwidth.
D) You must disable Spanning Tree on all edge switches until you have finished migrating edge switches?connections to the new distribution switches, which might introduce temporary broadcast storms.

3. Click the Exhibit button and view a network diagram and two switch configurations.

After you issue the command irf-port-configuration active on HP A5800 Switch members 4 and 5, the 10 Gigabit Ethernet link 1/0/25 is connected. What is the expected result?

A) IRF Member 3 becomes the Master.
B) IRF Member 2 becomes the Master.
C) IRF Member 5 becomes the Master.
D) IRF Member 4 becomes the Master.

4. This Cisco-based network is configured with PVST+.The Cisco network of an Example Corp,shown in exhibit is configured with PVST+.

What will happen if you change Spanning Tree mode to MST on C3750_1?

A) C3750_1 passes all the BPDUs sent by C6509_1 and C6509_2, and there is no change in topology.
B) C3750_1 generates a syslog message such as: *Mar 1 06:50:28.960: %SPANTREE-2PVSTSIM_FAIL: Blocking root port Gi1/0/1: Inconsistent inferior PVST BPDU received on VLAN 10, claiming root 10:0015.2b88.fd00" and uplink ports are blocked.
C) When C3750_1 realizes its neighbors are not MSTP compatible, it stops sending BPDUs.
D) On C3750_1, the root port for Common Spanning Tree will be the port leading to C6509_1.

5. Click the Exhibit button and view a network diagram and two switch configurations.
When interface Serial 4 of Router 2 fails, traffic from Router 1 destined for network 156.152.0.0/16 leaves AS 65001 via the Serial 3 interface of Router 1. The administrator prefers that this traffic leaves AS 65001 through interface Serial 5 of Router 2. Which configuration change will achieve the desired results?

A) Router-1#route-policy Policy permit node 10 apply preferred-value 500bgp 100 peer 16.0.0.2 route-policy Policy
B) Router-2#bgp 100 peer 16.0.0.1 next-hop-local
C) Router-2#route-policy Policy permit node 10 apply local-preference 500bgp 100 peer
156.152.5.1 route-policy Policy
D) Router-2#route-policy Policy permit node 10 apply preferred-value 500bgp 100 peer
156.152.5.1 route-policy Policy
