A network engineer of an ISP using Cisco IOS XR routers wants to limit the number of prefixes that BGP peers can accept.
To accomplish this task, the command maximum- prefix 1000 is used.
Which two results of this configuration are expected? (Choose two.)

• A.A warning message displays by default when 750 prefixes are received.
• B.A BGP peer resets when it receives 1001 prefixes.
• C.A warning message displays by default when 850 prefixes are received.
• D.A BGP peer ceases when it receives 1000 prefixes.
• E.A BGP peer ceases when it receives 1001 prefixes.
• F.The BGP peer tries to reestablish the session after one minute.
• G.A BGP peer resets when it receives 1000 prefixes.

After an engineer configures BGP in R1, it starts receiving this message
*Jun 29 13:30:50.122: %BGP-5-ADJCHANGE: neighbor 192.168.10.1 Down User reset Jun 29 13:30:52.341: %BGP-3-NOTIFICATION: sent to neighbor 192.168.10.1
2/6 (unacceptable hold time) 0 bytes
Which action makes the peering come back up again?

• A.Set up a hold-down timer higher.
• B.Set up a minimum hold-down timer higher.
• C.Make a soft reset to the peer.
• D.Set up a hello timer higher.

A network engineer for an ISP wants to reduce the number of iBGP adjacencies.
A merge is taking place with another ISP network, so the network engineer needs to make both ASNs look like a single network for the Internet.
Which BGP technology is most suitable?

• A.route reflector
• B.peer group
• C.confederation
• D.clustering

Which two statements about mapping multicast IP addresses to MAC addresses are true? (Choose two.)

• A.All multicast MAC addresses end with 0x0100.5E
• B.All destination MAC addresses begin with an octet of binary 1s
• C.The router performs the mapping before it hands the packet off to a switch
