A service provider has deployed new PEs using nV Edge technology based on Cisco ASR
9000 routers. How does the system mitigate against a split-brain state if all control plane and data plane links are lost?

• A.Both chassis stop receiving and forwarding data traffic until the control plane and data plane links are brought back up
• B.The two chassis send keepalive packets over any layer 2 cloud. The non-DSC chassis shuts down itself after it has received these additional keepalive packets
• C.Both chassis stay online operating as two different PEs
• D.The chassis located in the second rack automatically shuts down and only the first rack chassis stays operational

In the Apache Web Server configuration, the command KeepAlive ON is used to

• A.Allow a CSS to probe the server
• B.Allow a connection to be closed with a TCP RESET
• C.Allow persistent connections
• D.Allow the use of HTTP HEAD request
