HP Migrating &Troubleshooting Enterprise Networks Sample Questions:

1. The Cisco network of a company has the following characteristics:

What happens within the network? (Select three.)

A) On routers on which the EIGRP distance is still at default values, only OSPF networks are visible in the IP routing table.
B) There is a temporary disruption as the routers transitioning to OSPF routes calculate paths that work in this hybrid environment.
C) On routers on which the EIGRP distance is 220, OSPF networks replace EIGRP networks in the IP routing table.
D) On routers on which the EIGRP distance is still at default values, only EIGRP networks are still visible in the IP routing table.
E) There is no disruption to network connectivity, although some routers using OSPF routes and some are using EIGRP routes because the network paths are the same.
F) There is a disruption to network connectivity because EIGRP metrics and OSPF are very different and cannot produce the same path selection.
G) On routers on which the EIGRP distance is 220, OSPF redistributed networks are not visible in the IP routing table.

2. A company's Cisco network is configured with PVST+, and the distribution switches are the root and secondary roots in the existing VLANs. You want to migrate the company's network to implement MSTP. What will be your first step in performing the migration?

A) Configure MSTP parameters: region name, revision number, MSTP instances.
B) Disable Spanning Tree on all VLANs.
C) Migrate all switches to RapidPVST+.
D) Verify the Cisco switches and their IOS support MSTP.
E) Change path-cost method to long.

3. Which statement is true about BGP Route Refresh? (Select two.)

A) With Route Refresh, a BGP router stores all BGP prefixes sent by a BGP neighbor.
B) With Route Refresh, a BGP Hard Reset is used to generate inbound updates from a neighbor or to generate outbound updates to a neighbor.
C) BGP Route Refresh eliminates the need for a Hard Reset of the BGP connection with a BGP neighbor when route policies are changed.
D) Route Refresh is a feature for supported CPU functions with BGP routers that manage high number of IP Prefixes.
E) Route Refresh is advertised as a BGP capability to BGP neighbors during BGP session establishment.

4. Click the Exhibit button.

You are in the process of replacing Cisco switches at the distribution layer with HP E-Series switches. At this point, you have removed one of the Cisco distribution switches so that only one remains in the network. You have also connected one HP E-Series switch in that switch's place. As shown in the exhibit, the HP E-Series switch connects to the distribution layer, the edge, and the core. To eliminate network loops, the Cisco switches implement Rapid Per-VLAN Spanning Tree Plus (Rapid PVST+), and the HP E-Series switch implements Multiple Spanning Tree Protocol (MSTP). (Each connection to the core is a member of a single VLAN that is dedicated to that connection only and does not participate in the spanning tree.) The exhibit also shows the current Spanning Tree topology. You are now ready to migrate Edge1 so that it is connected to the HP E-Series switch only. What happens when you disable P1 on Edge1?

A) Link 2 comes up in all VLANs after a few seconds when the HP E-Series switch opens its P2.
B) Link 2 comes up in all VLANs after a several seconds because Edge1's Cisco uplinkfast feature does not interoperate with MSTP.
C) Link 2 becomes active in VLAN 1, which interoperates with MSTP, but flaps on VLANs 10 and 20 because the HP E-Series switch blocks BPDUs on those VLANs.
D) The loop that had existed on Link 2 in VLANs 10 and 20 is eliminated. Only after P2 on Edge1 recovers does the link come back up.

5. DRAG DROP
Click the Task button. A company network is EIGRP based. The company's IT department wants to migrate all Layer 3 devices to OSPF. Place the steps for migrating from EIGRP to OSPF using the "Overlay" method (where EIGRP and OSPF run in parallel) in the correct order.
