Refer to the exhibit. Routers CE1 and CE2 are in AS 65530. which is multihomed for Internet access.
An engineer expects inbound traffic to AS 65530 to arrive from PE1. but it is coming from PE2 instead PE1 and PE2 routers are connected with CE routers through the same bandwidth Which action must be taken to correct the problem?
On router CE2, configure inbound routes from PE2 to CE2 with a local-preference value of 50 or greater.
Configure router CEI to prepend the AS path to routes it receives from PE 1.
Set the local-preference value on router CEI to 100 or greater
On router PEI , change the origin for routes that are redistributed from CEI to CE2.

Refer to the exhibit Networks 172.16.31.0/24 and 172 16 30.0/24 are advertised in area 34. and network 172.22 10.0/24 is advertised in area 0. A recent security review discovered that users connected to routers R1 and R2 have been making unauthorized access to an application running on network 172 16 31 0/24 An engineer determined that routers R1 and R2 are receiving updates for network 17 16 31 0/24 Which action resolves the issue?

low order 23 bits
lower-order 24 bits
Refer to the exhibit.
Refer to the exhibit. An engineer is troubleshooting an issue with this network and notices that prefixes from R3 are missing on the R1 routing table Due to repeated ASN when the 10 0 0 0'8 prefix from R3 arrives at R1, BGP automatically rejects it There is no prefix-list on R1 which blocks the traffic from R3 What should the engineer do to fix the problem so that BGP allows that prefix on R1?

Configure the allowas-in command on RI.
Configure the next-hop-self command on R2.
Configure identical confederation ASNs on RI and R2.
