What is the purpose of floating self-IP addresses?
A.
to define an address that grants administrative access to either system at any time
B.
to define an address that allows either system to initiate communication at any time
C.
to define an address that allows network devices to route traffic via a single IP address
D.
to define an address that gives network devices greater flexibility in choosing a path to forward
traffic
to define an address that allows network devices to route traffic via a single IP address
Which parameters are set to the same value when a pair of BIG-IP devices are synchronized?
A.
host names
B.
system clocks
C.
profile definitions
D.
VLAN fail-safe settings
E.
MAC masquerade addresses
profile definitions
Which two statements are true concerning the default communication between a redundant pair of
BIG-IP systems? (Choose two.)
A.
Synchronization occurs via a TCP connection using ports 683 and 684.
B.
Connection mirroring data is shared via a TCP connection using port 1028.
C.
Persistence mirroring data is shared via a TCP connection using port 1028
D.
Connection mirroring data is shared through the serial fail-over cable unless network fail-over is
enabled.
Connection mirroring data is shared via a TCP connection using port 1028.
Persistence mirroring data is shared via a TCP connection using port 1028
Which two methods can be used to determine which BIG-IP is currently active? (Choose two.)
A.
The bigtop command displays the status.
B.
Only the active system's configuration screens are active.
C.
The status (Active/Standby) is embedded in the command prompt.
D.
The ifconfig -a command displays the floating addresses on the active system.
The bigtop command displays the status.
The status (Active/Standby) is embedded in the command prompt.
As a part of the Setup Utility, the administrator sets the host name for the BIG-IP. What would be
the result if the two systems in a redundant pair were set to the same host name?
A.
Host names do not matter in redundant pair communication
B.
In a redundant pair, the two systems will always have the same host name. The parameter is
synchronizedbetween the systems.
C.
The first time the systems are synchronized the receiving system will be assigned the same
self-IPaddresses as the source system.
D.
When the administrator attempts to access the configuration utility using the host name, they
will alwaysconnect to the active system.
The first time the systems are synchronized the receiving system will be assigned the same
self-IPaddresses as the source system.
When network fail-over is enabled, which of the following is true?
A.
The fail-over cable status is ignored. Fail-over is determined by the network status only.
B.
Either a network failure or loss of voltage across the fail-over cable will cause a fail-over.
C.
A network failure will not cause a fail-over as long as there is a voltage across the fail-over
cable.
D.
The presence or absence of voltage over the fail-over cable takes precedence over network
fail-over.
A network failure will not cause a fail-over as long as there is a voltage across the fail-over
cable.
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
It is an optional feature of each virtual server
Which statement is true regarding fail-over?
A.
Hardware fail-over is disabled by default.
B.
Hardware fail-over can be used in conjunction with network failover.
C.
If the hardware fail-over cable is disconnected, both BIG-IP devices will always assume the
active role.
D.
By default, hardware fail-over detects voltage across the fail-over cable and monitors traffic across theinternal VLAN.
Hardware fail-over can be used in conjunction with network failover.
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.
It is part of a profile definition.
Assume the bigd daemon fails on the active system. Which three are possible results? (Choose
three.)
A.
The active system will restart the bigd daemon and continue in active mode
B.
The active system will restart the tmm daemon and continue in active mode.
C.
The active system will reboot and the standby system will go into active mode.
D.
The active system will fail-over and the standby system will go into active mode.
E.
The active system will continue in active mode but gather member and node state information
from thestandby system.
The active system will restart the bigd daemon and continue in active mode
The active system will reboot and the standby system will go into active mode.
The active system will fail-over and the standby system will go into active mode.
What is the purpose of MAC masquerading?
A.
to prevent ARP cache errors
B.
to minimize ARP entries on routers
C.
to minimize connection loss due to ARP cache refresh delays
D.
to allow both BIG-IP devices to simultaneously use the same MAC address
to minimize connection loss due to ARP cache refresh delays
Which process or system can be monitored by the BIG-IP system and used as a fail-over trigger in
a redundant pair configuration?
A.
bandwidth utilization
B.
duplicate IP address
C.
CPU utilization percentage
D.
VLAN communication ability
VLAN communication ability
