Refer to the exhibit. You want to minimize the downtime that results from supervisor engine switchovers on Cisco 6500 Series Switches and Cisco 7600 Series Routers. To achieve this, you are considering deploying a Cisco Nonstop Forwarding with Stateful Switchover solution using OSPF.

In the exhibit you can see the output of the show ip ospf neighbor detail command.
Which trait of systems using Cisco Nonstop Forwarding with Stateful Switchover and OSPF is shown in the exhibit output and will impact your plan?（）

A. An information trap is sent to the SNMP server.
B. Informational and debug messages are logged to the syslog server.
C. All messages are sent to the logging host, where selections are made.
D. All messages from emergencies to informational are sent to the logging host.

A. When a router receives a failure response, it stops querying authentication methods.
B. When a router receives an error response, it stops querying authentication methods.
C. If the router receives a failure response from an authentication method, it queries the next method.
D. The router does not differentiate between failure and error responses; the authentication process is always interrupted.
E. If it receives no response from the authentication method, a router will determine the error condition on its own; the router also has the option to proceed to the next method in a list if configured accordingly.

A. It is achieved by using more than one HSRP group.
B. It is done in regards to either round robin or weight basis.
C. It is used to offload the active router in a certain HSRP group.
D. Single group HSRP is used to achieve more efficient link utilization.
E. The return traffic is influenced by HSRP load sharing configuration.
