Questions # 15:

An engineer must peer with an ISP for internet connectivity using BGP, initially, the engineer wants to receive only specific prefixes from the ISP and a default route. However, the solution must provide the flexibility to add prefixes in the future at short notice. The ISP has a two-week change process in place. Which route filtering solution must the engineer employ?

Options:

A.

Request a limited internet routing table and a default route from the ISP and configure the BGP max-limit to 1 with an access list that permits only the specific internet prefixes and blocked networks


B.

Request only the required prefixes and default route be advertised from the ISO with whitelisted networks


C.

Request a full internet routing table and a default route from the ISP and configure inbound route filtering with a prefix list that permits the default route and required prefixes


D.

Configure outbound route filtering on the enterprise and ISP so that the enterprise tell the ISP which prefixes are required

Questions # 16:

Refer to the exhibit.

Question # 16

EIGRP has been configured on all links. The spoke nodes have been configured as EIGRP stubs, and the WAN links to R3 have higher bandwidth and lower delay than the links to R4. When a link failure occurs at the R1-R2 link, what happens to traffic on R1 that is destined for a subnet attached to R2?

Options:

A.

R1 has no route to R2 and drops the traffic


B.

R1 load-balances across the paths through R3 and R4 to reach R2


C.

R1 forwards the traffic to R3, but R3 drops the traffic


D.

R1 forwards the traffic to R3 in order to reach R2
