HP Migrating &Troubleshooting Enterprise Networks Sample Questions:

1. A company's network includes Cisco switches that are running PVST+. The distribution switches are configured as root and secondary root for all existing VLANs. There are 80 switches at the
edge. In order to prepare for installing HP switches at the edge, the company's IT department wants to migrate PVST+ to MSTP.Which actions will help this company reduce downtime during the migration? (Select three.)

A) causing failover on one distribution switch during the migration period
B) reducing MSTP Hello timer to 1, forwarding-delay to 4, and max-age to 6
C) changing the method of path cost to 'long' on Cisco edge switches
D) changing the priority of uplink ports on Cisco edge switches
E) pre-configuring the MSTP region name, revision number, and VLAN-to-instance mappings on all switches before changing the mode to MSTP
F) reducing MSTP Hello timer to 2, forwarding-delay to 6, and max-age to 8
G) changing the priority of the uplink ports on HP edge switches

2. RRPP statistics for an HP A-Series switch indicate that Hellos are being received on the secondary port but do not indicate that Hellos are being sent on the primary port. What most likely caused this?

A) A link-down message has been sent by the Master node.
B) The switch is in Edge node mode.
C) The primary port is down.
D) The RRPP ring is in a fail state.
E) The switch is in Transit node mode.

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) The connection between the existing distribution switches and the parallel network might become a bottleneck during the migration process unless you plan sufficient bandwidth.
B) This approach requires you to shut down the network for at least several hours, because of the network size.
C) 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.
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.

4. The Cisco network of a company is EIGRP-based. Currently, the routers include both internal and external EIGRP networks. OSPF will be added on all routers, including OSPF 'network' and 'redistribution' commands. All routers are using default administrative distances.Which types of routes will be found in the IP routing tables?

A) internal EIGRP and external OSPF networks
B) internal and external OSPF networks only
C) external EIGRP and internal OSPF networks
D) internal and external EIGRP networks only

A provider of MPLS services configures MPLS Layer-3 VPN services for two customers. Each customer has three branch offices that will be interconnected by MPLS Layer-3 VPNs. The following are address blocks chosen by the customers for each site as shown in the chart:

The provider uses OSPF as its IGP with the Loopback 0 addresses shown as the OSPF router-id and the MPLS LSR-ID. Customer A uses a default route on each site. Customer B uses eBGP to exchange routes with the provider. All MPLS layer-3 VPNs are functioning properly. Which configuration change will cause Customer-A Site 1 to lose access to Customer-A Site 2?

A) [PE-1]
bgp 1
undo import-route static
B) [PE-3]
bgp 1
undo peer 16.0.0.1 reflect-client
C) [P-10]
ip route static 10.1.0.0 16 null 0 preference 9
D) [P-10]
ospf 1
area 0
abr-summary 16.0.0.2 30 cost 1000
E) [PE-1]
int vlan 100
