Voice traffic between two campus enterprise networks is growing. The network designers decide to add a second 10-Mb Metro Ethernet service parallel to their original 10-Mb service in order to provide more bandwidth and diversity. The QoS profile will be the same on the new 10-Mb service due to the voice stability on the first Metro Ethernet link. When the second link is added to the OSPF domain, which traffic design consideration would have the most impact on the voice traffic when both links are active?

A. per-destination IP address basis

B. per-flow basis

C. per-packet basis

D. per-source IP address basis

A network administrator is in charge of multiple IPsec VPN headend devices that service thousands of remote connectivity, point-to-point, IPsec/GRE tunnels. During a recent power outage, in which it was found that a backup power supply in one of those headend devices was faulty, one of the headend routers suffered a complete shutdown event. When the router was successfully recovered, remote users found intermittent connectivity issues that went away after several hours. Network operations staff accessed the headend devices and found that the recently recovered unit was near 100% CPU for a long period of time. How would you redesign the network VPN headend devices to prevent this from happening again in the future?

A. Move the tunnels more evenly across the headend devices.

B. Implement Call Admission Control.

C. Use the scheduler allocate command to curb CPU usage.

D. Change the tunnels to DMVPN.

You are designing a network that includes IP QoS. Which two architectures could be used to ensure that IP QoS is implemented properly? (Choose two.)

A. Differentiated Services, where the user, with the assistance of the RSVP signaling protocol, reserves the resources end to end before sending the data

B. Integrated Services, where the user, with the assistance of the RSVP signaling protocol, reserves the resources end to end before sending the data

C. Integrated Services, which relies on the information carried within each packet to make resource-allocation decisions at each network node

D. Differentiated Services, which relies on the information carried within each packet to make resource allocation decisions at each network node

E. Integrated Services, where the user, with the assistance of the DSCP signaling protocol, reserves the resources end to end before sending the data

Refer to the exhibit.

You must ensure that both core A and core B devices have only the minimum information required for reaching the spoke routers yet maintain full reachability during network failures. Which of the following design solutions accomplishes these requirements?

A. Route summarization, with specific route leaking on hubs A and B

B. Route summarization, with GRE tunnel on hubs A and B

C. Implement PfR enhancements on hubs A and B

D. Implement ODR for hub-to-spoke routing

A company wants a design that would support OSPF through a service provider ATM network. Which two OSPF network types should the designer use to establish OSPF neighborship between OSPF routers through the ATM network? (Choose two.)

A. A broadcast network will always work through ATM networks.

B. A broadcast network will work when the broadcast support is explicitly configured at the ATM network.

C. Explicit neighbor statements are required when a nonbroadcast network is configured.

D. Explicit neighbor statements are required when a point-to-multipoint network is configured.

E. A nonbroadcast network does not require DR selection.

Refer to the exhibit.

In the DWDM network, a ring topology carries multiple services between two sites. Which option describes the employed protection design?

A. Y-cable protection

B. Splitter protection

C. Client protection

D. UDLD

E. FEC protection

You are designing a GET VPN solution for an existing branch network. The existing network has the following characteristics: 50 remote sites (with an additional 30 remote sites expected over the next 3 years), Connectivity between all sites is via MPLS Layer 3 VPN service from a single provider, OSPF is the routing protocol used between provider edge and customer edge routers, The customer edge routers will become group members performing the encryption between sites.

Which additional routing protocol, if any, should you use for the overlay routing between the group members?

A. EIGRP

B. OSPF (with a different process ID)

C. eBGP

D. RIPv2

E. No additional protocol is necessary

Refer to the exhibit.

A customer currently has a large EIGRP-based network with several remote sites attached. All remote sites connect to the two corporate data centers, depicted as 10.1.1.0 and 10.1.2.0. The customer has experienced several network-wide failures where neighbors were stuck-in-active and had other network stability issues due to some links flapping. Which two redesign options increase stability and reduce the load on the remote site routers, still maintaining optimal routing between remote sites and the two data centers? (Choose two)

A. Set the data center routers as stub-routers

B. Perform summarization at the data centers, selectively leaking routes sent to the remote sites

C. Perform summarization at the remote sites, selectively leaking routes sent to the data centers

D. Set the hello interval timer to be larger than the hold interval

E. Increase the hold interval to accommodate lost hello packets on error-prone links
