Question No. 1

Which Layer 3 VPN attribute allows different customers to connect to the same MPLS network wrth overlapping IP ranges?

Show Answer Hide Answer
Correct Answer: D

In a Layer 3 VPN (Virtual Private Network) over an MPLS (Multiprotocol Label Switching) network, the attribute that allows different customers to connect with overlapping IP ranges is the Route Distinguisher (RD)123.

RD is a unique identifier that is prepended to each IP address in a customer's VPN to create a unique VPNv4 address.This allows customers to use overlapping IP addresses without conflict123.The RD makes it possible for the same IP prefix to exist in different VPNs, which is crucial when customers have overlapping IP ranges123.

Question No. 2

Network engineer must configure an ElGRP stub router at a site that advertises only connected and summary routes. Which configuration performs this task?

A)

B)

C)

D)

Show Answer Hide Answer
Correct Answer: B

In EIGRP (Enhanced Interior Gateway Routing Protocol), a stub router is one that is connected to one or more neighbors and should not be a transit router1. The EIGRP stub routing feature improves network stability, reduces resource utilization, and simplifies the stub router's configuration1.

The network engineer wants to configure an EIGRP stub router that advertises only connected and summary routes. This can be achieved with the configuration provided in Option B:

router eigrp 100

eigrp stub summary

This configuration ensures that the EIGRP stub router advertises only connected and summary routes12. The summary keyword after the eigrp stub command indicates that the router should advertise only auto-summarized or statically configured summary routes12.

Question No. 3

Refer to the exhibit.

Refer to the exhibit R1 cannot establish a neighbor relationship with R2 Which action resolves the issue"?

Show Answer Hide Answer
Correct Answer: A

In OSPF (Open Shortest Path First), the MTU (Maximum Transmission Unit) size must match on both sides of a link for OSPF neighbors to form an adjacency12.If the MTU sizes do not match, the OSPF adjacency will not form, and the routers will not become neighbors12.

In this case, R1 cannot establish a neighbor relationship with R2.One possible reason for this could be a mismatch in the MTU size on the interfaces of R1 and R212.

To resolve this issue, you can configure themtu ignorecommand on the interfaces of R1 and R2 (Option A).This command allows OSPF to ignore the MTU size when determining if it can form an adjacency with a neighbor12.This means that even if the MTU sizes do not match, OSPF will still form an adjacency, and R1 and R2 will become neighbors12.
