• Question 1:

  A virtual server is defined per the charts. The last five client connections were to members C, D, A, B, B. Given the conditions shown in the above graphic, if a client with IP address 205.12.45.52 opens a connection to the virtual server, which member will be used for the connection?

  

  A. 172.16.20.1:80
  B. 172.16.20.2:80
  C. 172.16.20.3:80
  D. 172.16.20.4:80
  E. 172.16.20.5:80
  D. 172.16.20.4:80

• Question 2:

  Assuming that systems are synchronized, which action could take place if the fail-over cable is connected correctly and working properly, but the systems cannot communicate over the network due to external network problems?

  A. If network fail-over is enabled, the standby system will assume the active mode.
  B. Whether or not network fail-over is enabled, the standby system will stay in standby mode.
  C. Whether or not network fail-over is enabled, the standby system will assume the active mode.
  D. If network fail-over is enabled, the standby system will go into active mode but only until the network recovers.
  B. Whether or not network fail-over is enabled, the standby system will stay in standby mode.

• Question 3:

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

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

• Question 4:

  How is MAC masquerading configured?

  A. Specify the desired MAC address for each VLAN for which you want this feature enabled.
  B. Specify the desired MAC address for each self-IP address for which you want this feature enabled.
  C. Specify the desired MAC address for each VLAN on the active system and synchronize the systems.
  D. Specify the desired MAC address for each floating self-IP address for which you want this feature enabled.
  A. Specify the desired MAC address for each VLAN for which you want this feature enabled.

• Question 5:

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

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

• Question 6:

  Where is connection mirroring configured?

  A. It an option within a TCP profile.
  B. It is an optional feature of each pool.
  C. It is not configured; it is default behavior.
  D. It is an optional feature of each virtual server.
  D. It is an optional feature of each virtual server.

• Question 7:

  Given that VLAN fail-safe is enabled on the external VLAN and the network that the active BIG- IP's external VLAN is connected to has failed, which statement is always true about the results?

  A. The active system will note the failure in the HA table.
  B. The active system will reboot and the standby system will go into active mode.
  C. The active system will fail-over and the standby system will go into active mode.
  D. The active system will restart the traffic management module to eliminate the possibility that BIG-IP is the cause for the network failure.
  A. The active system will note the failure in the HA table.

• Question 8:

  Where is persistence mirroring configured?

  A. It is always enabled.
  B. It is part of a pool definition.
  C. It is part of a profile definition.
  D. It is part of a virtual server definition.
  C. It is part of a profile definition.

• Question 9:

  Assuming other fail-over settings are at their default state, what would occur if the fail-over cable were to be disconnected for five seconds and then reconnected?

  A. As long as network communication is not lost, no change will occur.
  B. Nothing. Fail-over due to loss of voltage will not occur if the voltage is lost for less than ten seconds.
  C. When the cable is disconnected, both systems will become active. When the voltage is restored, unit two will revert to standby mode.
  D. When the cable is disconnected, both systems will become active. When the voltage is restored, both systems will maintain active mode.
  C. When the cable is disconnected, both systems will become active. When the voltage is restored, unit two will revert to standby mode.

• Question 10:

  Which two statements describe differences between the active and standby systems? (Choose two.)

  A. Monitors are performed only by the active system.
  B. Fail-over triggers only cause changes on the active system.
  C. Virtual server addresses are hosted only by the active system.
  D. Configuration changes can only be made on the active system.
  E. Floating self-IP addresses are hosted only by the active system.
  C. Virtual server addresses are hosted only by the active system.
  E. Floating self-IP addresses are hosted only by the active system.
