Question 8.
With two BIG-IPs in a redundant pair, which statement best describes what happens when some event triggers a failover?
A. The Standby BIG-IP detects the failure and reboots itself.
B. The Active BIG-IP waits to receive a message from the Standby BIG-IP, then relinquishes
control to the Standby.
C. The Active BIG-IP stops sending the signal indicating it is active, whereupon the Standby BIG-

A. If Network Failover is enabled, the Standby BIG-IP will assume the Active role.
B. Regardless of whether Network Failover is enabled, the Standby BIG-IP will assume the Active
role.
C. Regardless of whether Network Failover is enabled, the Standby BIG-IP will maintain the
Standby role.
D. If Network Failover is enabled, the Standby BIG-IP will assume the Active role, but only until
the network recovers.
Answer: C
Question 11.
When Network Failover is enabled, what is the interaction with the serial failover cable?
A. The serial failover cable must be disconnected if Network Failover is enabled.
B. The serial failover cable status is ignored. Failover is determined by the Network Failover
status only.
C. Either a network failure or loss of voltage across the serial failover cable will cause a failover.
D. A network failure will not cause a failover as long as the voltage is sent across the serial
failover cable.
Answer: D
Question 12.
If an unexpected event occurs that causes both BIG-IPs to become Active, which recovery processes are valid? (Choose two.)
A. If the BIG-IPs are relying on the serial failover cable, once the voltage is restored the systems
will recover automatically by default.
B. If the BIG-IPs are relying on Network Failover, once the network is restored the systems will
recover automatically by default.
C. If the BIG-IPs are relying on Network Failover, the network must be restored and then the
administrator must force one system to become Standby.
D. If the BIG-IPs are relying on the serial failover cable, the voltage must be restored and then the
Administrator must force one BIG-IP to become Standby or pre-configure one BIG-IP to
become Standby.
Answer: B, D
Question 13.
Where is Connection Mirroring configured?

C. It is configured as a property of each Virtual Server.
D. It is configured as a property of each Node.
Answer: C
Question 14.

A. All connections are lost.
B. When persistence mirroring is enabled, active connections are maintained even on failover.
C. Long-lived connections such as telnet and FTP are maintained, but short-lived connections
such as HTTP are lost.
D. All active connections are lost, but new connections are initiated by the newly active BIG-IP,
resulting in minimal client downtime.
Answer: A
Question 15.
Where is Persistence Mirroring configured?
A. It is configured as a property of the Pool.
B. It is not configured. It is a default feature.
C. It is configured as a property of the Virtual Server.
D. It is configured as a property of the Node.
Answer: A
Question 16.
When using Cookie Persistence on a synchronized redundant pair of BIG-IPs, what configurations are necessary to ensure that persistence is not lost if a failover occurs?
A. Cookie Persistence will not be maintained if failover occurs.
B. Other than enabling Cookie Persistence, nothing needs to be done.
C. Within the Pool's persistence properties, Mirroring must be selected.
D. Select Cookie Persistence Mirroring under Advanced Properties/Cookie Persistence.
Answer: B
Question 17.
When Simple Persistence is configured and Persistence Mirroring is enabled, how frequently does the Active BIG-IP update the Standby BIG-IP concerning persistence table entries?

C. at the same frequency that the Network Failover heartbeat occurs
D. every time a persistence record is created or deleted
Answer: D
Question 18.
What is the purpose of MAC masquerading?
A. to trigger a BIG-IP failover when the network is unreachable
B. to allow nodes to use just one default gateway address
C. to minimize connectivity loss due to ARP cache refresh delays after a failover occurs
D. to allow two BIG-IPs to be used in Active/Active mode
Answer: C
Question 19.
