Which statement is true concerning the default communication between a redundant pair of BIG-IP devices?
A. Communication between the systems cannot be effected by port lockdown settings.
B. Data for both connection and persistence mirroring are shared through the same TCP connection.
C. Regardless of the configuration, some data is communicated between the systems at regular intervals.
D. Connection mirroring data is shared through the serial fail-over cable unless network fail-over is enabled.
When upgrading a BIG-IP redundant pair, what happens when one system has been updated but the other has not?
A. Synching should not be performed.
B. The first system to be updated will assume the Active role.
C. This is not possible since both systems are updated simultaneously.
D. The older system will issue SNMP traps indicating a communication error with the partner.
When using the setup utility to configure a redundant pair, you are asked to provide a "Failover Peer IP". Which address is this?
A. an address of the other system in its management network
B. an address of the other system in a redundant pair configuration
C. an address on the current system used to listen for fail-over messages from the partner BIG-IP
D. an address on the current system used to initiate mirroring and network fail-over heartbeat messages
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.
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.
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.
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.
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.
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.
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.
