As part of a new network design, you are helping the Network Management Team to develop a proactive report to identify places in the network where problems may happen. The network management tool can poll the network devices only via SNMP GET operations. Which two threshold-crossing metrics should you include in this report? (Choose two.)

• A.packet loss
• B.CPU utilization
• C.heat dissipation
• D.IP reachability
• E.energy consumption
• F.link bandwidth utilization

In this network presented in the following exhibit, traffic destined for 10.1.3.1 arrives at P4S-R5. Which path will be taken by the traffic from here and why?

• A.It will take the path P4S-R3, P4S-R2, P4S-R1, because OSPF always prefers paths within an area.
• B.It will not take any path; the traffic will be dropped because P4S-R2 is in a different autonomous system than P4S-R1 or P4S-R3.
• C.It will take the path the path P4S-R4, P4S-R3, P4S-R2, P4S-R1, because this is the lowest cost path.
• D.It will not take any path; the traffic will be dropped because the summary (type 3) LSA advertised by P4S-R1 into area 1 will not be readvertised back into area 0.

You have been asked to establish a design that will allow your company to migrate from a WAN service to a Layer 3 VPN service. In your design, you are keeping some WAN links between critical sites as a backup for this service. You plan to use OSPF as your IGP and BGP for the PE-CE protocol. When the Layer 3 VPN service is available, how will you prevent transit traffic over the backup links?

• A.Use conditional advertisement only when the Layer 3 service is down.
• B.Redistribute routes at the CE as external type 2.
• C.Manually turn off the backdoor link when the Layer 3 service is up.
• D.Redistribute routes at the CE as external type 1.

Which two options are two advantages of summarizing networks at the aggregation layer rather than at the core? (Choose two.)

• A.It prevents black hole routing.
• B.It avoids network-wide impact upon VLAN changes local to the aggregation devices.
• C.It prevents the core from having unnecessary routes.
• D.It no longer needs a core layer.
