R1 has established an EBGP peering relationship

connection with an ISP The administrator would like to ensure that all traffic from the ISP enters the

autonomous system through router R1 Which BGP attribute can the administrator configure on routers R1 and

19 Which routes are available to a BGP speaker to advertise to peers once an adjacency is formed

only routes in the IP routing table

only routes in the BGP forwarding database

only routes that are learned from IBGP peers in the same autonomous system

any route in either the IP routing table or BGP forwarding database

20 What is a disadvantage to multihoming and accepting only a default route from each ISP

Because of load balancing between ISPs suboptimal routing may occur

Because routers will select the edge router based on the IGP metric suboptimal routing may occur

Because routing loops within the IGP routing domain may occur only a single ISP connection can be used

Because no more than one default route can be advertised into the IGP routing domain only a single ISP

connection can be used

Refer to the exhibit BGP sessions are established between all routers Router RTC has the local preference for network

20916520022427 set to 200 and router RTB has a local preference set to 150 for the same network Which router will be used

by RTA as a next hop to reach network 20916529922427

Refer to the exhibit Router R1 is receiving the prefix 10220016 from an IBGP peer The prefix appears in the

BGP table of R1 but not in the IP routing table What could be preventing R1 from installing 10220016 in the

routing table

automatic summarization disabled

EBGP multihop misconfiguration

incorrect use of the update-source command

route dampening

synchronization

14 How can static routes be dynamically injected into BGP

Create the static routes with an administrative distance equal to BGP

Apply the redistribute static command to the BGP configuration

Create a prefix list that covers the scope of the networks that are specified by the static routes

Use route maps instead of static routes to dynamically update the convergence

15 Which two options best describe an exterior routing protocol (EGP) (Choose two)

an interdomain routing protocol

an intradomain routing protocol

a routing protocol that is used for intradomain routing such as IS-IS and OSPFv3

a routing protocol that exchanges routing information within an autonomous system

a routing protocol that exchanges routing information between different autonomous systems

any route in either the IP routing table or BGP forwarding database

20 What is a disadvantage to multihoming and accepting only a default route from each ISP

Because of load balancing between ISPs suboptimal routing may occur

Because routers will select the edge router based on the IGP metric suboptimal routing may occur

Because routing loops within the IGP routing domain may occur only a single ISP connection can be used

Because no more than one default route can be advertised into the IGP routing domain only a single ISP

connection can be used
