Refer to the exhibit. An ISP provides shared VoIP Extranet services to a customer in VRF-100 with these settings:
The VoIP services are hosted in the 198.19.100.0/24 space.
The customer has been assigned the 198.18.1.0/29 IP address block. VRF-100 is assigned import and export route target 65010:100.
Which configuration must the engineer apply to PE-1 to provision VRF-100 and provide access to the shared services?

Correct Answer: D

After you analyze your network environment, you decide to implement a full separation model for Internet access and MPLS L3VPN services For which reason do you make this decision?

1. A. It enables you to choose whether to separate or centralize each individual service.
2. B. It is easier to manage a system in which services are mixed
3. C. It requires only one edge router
4. D. It enables EGP and IGP to operate independently

Correct Answer: D

Refer to the exhibit.

EIGRP is running between routers R5 and R1, and OSPF is used in the rest of the network. Users in a network attached to router R3 need to access a server connected to R5. Which task must the engineer perform so that only the users attached to R3 are able to access the server, but no other network is shared to OSPF?

1. A. Configure redistribution using route maps to filter the routes that are shared
2. B. Configure redistribution using an offset list to filter the routes that are shared.
3. C. Configure an OSPF virtual link between R1 and R3 to route traffic between the two areas.
4. D. Configure R1 as a stub router for EIGRP and OSPF so that only the default route is shared

Correct Answer: A

An ISP Is Implementing end-to-end fault monitoring for a customer based on the IEEE 802.3ah standard. The solution must detect when 15 or more corrupted Ethernet packets arrive within 10 ms and stop propagating traffic through the ISP backbone network or to the customer side. Which configuration must the ISP engineer apply?
