Refer to the exhibit. ASN 64501 currently reaches the networks under the 10.0.0.0/8 prefix via the North_B router, which is a slow backup link.
The administrator of ASN 64502 wants traffic from ASN 64501 to 10.0.0.0/8 to travel via the primary link North_A.
Which change to the network configuration accomplishes this task?

• A.Set a lower MED between North_B and South_B
• B.Set a Lower Weight value for incoming traffic on North_A
• C.Advertise the 10.0.0.0/8 prefix through North_B and specific subnets through North_A
• D.Set a higher local preference between North_A and South_A

Refer to the exhibit. An engineer working for a private service provider with an employee ID:
1234:56:789 is configuring BGP in AS 400, AS 500, and AS 600 to set up BGP peering. The engineer reported that 172.16.10.0/24 is not installed in the R2 RIB. RI and R5 receive the prefix
172.16.10.0/24 in the BGP routing table. Which configuration must be implemented to stop receiving prefix 172.16.10.0/24 in the BGP table?

• A.Configure bgp suppress-inactive under BGP address-family ipv4 unicast on R2.
• B.Configure route-map blockprefix out under BGP on R2.
• C.Configure bgp suppress-inactive under BGP address-family ipv4 unicast on R1 and R5.
• D.Configure route-map blockprefix in under BGP on R1 and R5.

In an EVPN operation how does the PE determine and advertise Ethernet segment reachability?

• A.The PE discovers remote ESIs and determines their redundancy mode.
• B.The PE discovers the remote PEs in the EVI and builds a flood list linked with the EVI.
• C.The PE discovers and shares routing information for the B-MAC addresses associated with local Ethernet segments.
• D.The PE discovers other PEs in the same Ethernet segment and elects a DF.

While implementing TTL security, you issue the PE(config-router-af)#neighbor 2.2.2.2 ttl-security hops 2 command.
After you issue this command, which BGP packets does the PE accept?

• A.to 2.2.2.2, with a TTL of less than 253
• B.from 2.2.2.2, with a TTL of 253 or more
• C.from 2.2.2.2, with a TTL of less than 2
• D.to 2.2.2.2, with a TTL of 2 or more
