A . The new switch happened to be running Cisco Catalyst operating system， while the other network switches were running Cisco IOS Software. B . The configuration revision of the new switch was higher than the configuration revision of the production VTP domain. C . The link costs on the new switch are set to a high value， causing all ports on the new switch to go into a forwarding mode and none into blocking mode， thereby causing a spanning-tree loop. D . The ports connecting to the two switches have been configured incorrectly. One side has the command switchport mode access and the other switchport mode trunk.

If a session switched from the DB_GRP consumer group to another consumer group because it exceeded the prescribed switch time， then that session would not execute if the active session pool for the new consumer group was full. E . If a session switched from the DB_GRP consumer group to another consumer group because it exceeded the prescribed switch time， then that session would execute even if the active session pool for the new consumer group was full.
