Assuming there are open connections through an active system's virtual servers and a fail-over occurs, by default, what happens to the connections?

  1. All open connections are lost.
  2. All open connections are maintained.
  3. When persistence mirroring is enabled, open connections are maintained even if a fail-over occurs.
  4. Long-lived connections such as Telnet and FTP are maintained, but short-lived connections such as HTTP are lost.
  5. All open connections are lost, but new connections are initiated by the newly active BIG-IP, resulting in minimal client downtime.

Answer(s): A



Which VLANs must be enabled for a SNAT to perform as desired (translating only desired packets)?

  1. The SNAT must be enabled for all VLANs.
  2. The SNAT must be enabled for the VLANs where desired packets leave the BIG-IP.
  3. The SNAT must be enabled for the VLANs where desired packets arrive on the BIG-IP.
  4. The SNAT must be enabled for the VLANs where desired packets arrive and leave the BIG-IP.

Answer(s): C

When can a single virtual server be associated with multiple profiles?

  1. Never. Each virtual server has a maximum of one profile.
  2. Often. Profiles work on different layers and combining profiles is common.
  3. Rarely. One combination, using both the TCP and HTTP profile does occur, but it is the exception.
  4. Unlimited. Profiles can work together in any combination to ensure that all traffic types are supported in a given virtual server.

Answer(s): B



Which action will take place when a failover trigger is detected by the active system?

  1. The active device will take the action specified for the failure.
  2. The standby device also detects the failure and assumes the active role.
  3. The active device will wait for all connections to terminate and then fail-over.
  4. The standby device will begin processing virtual servers that have failed, but the active device will continue servicing the functional virtual servers.

Answer(s): A
