質問 2：
A BIG-IP system has the following configuration:
* SNAT is set to Auto Map
* There are two VLANs internal and external
* Default route is pointed to the gateway on external VLAN
* Self P for internal VLAN is 1921.1.2
* Self IP for external VLAN is 192.1.2.2
* Floating IP addresses for internal VLAN is 192.1.1.1
* Floating IP addresses for external VLAN is 192.1.2.1
* The Virtual Server IP address is 192.1.1.100
Which IP address does the BIG-IP system use first when traffic reaches the servers on the internal VLAN?
A. 192.1.2.1
B. 192.1.1.100
C. 192.1.2.2
D. 192.1.1.1
正解：D

質問 3：
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 gives network devices greater flexibility in choosing a path to forward traffic
C. to define an address that allows network devices to route traffic via a single IP address
D. to define an address that allows either system to initiate communication at any time
正解：C

質問 4：
The 8IG-IP Administrator generates a qkview using "qkview -SO" and needs to transfer the output file via SCP.
Which directory contains the output file?
A. /var/config
B. /var/local
C. /var/log
D. /var/tmp
正解：D

質問 5：
Which statement is true concerning the default communication between a redundant pair of BIG-IP devices?
A. Regardless of the configuration, some data is communicated between the systems at regular intervals.
B. Data for both connection and persistence mirroring are shared through the same TCP connection.
C. Communication between the systems cannot be effected by port lockdown settings.
D. Connection mirroring data is shared through the serial fail over cable unless network failover is enabled.
正解：B

質問 6：
A site has six members in a pool. All of the servers have been designed, built, and configured with the same applications. It is known that each client's interactions vary significantly and can affect the performance of the servers.
If traffic should be sent to all members on a regular basis, which loadbalancing mode is most effective if the goal is to maintain a relatively even load across all servers?
A. Observed
B. Ratio
C. Priority
D. Round Robin
正解：A

質問 7：
Which statement accurately describes the difference between two loadbalancing modes specified as "member" and "node"?
A. Loadbalancing options referencing "nodes" are available only when the pool members are defined for the "any" port.
B. When the loadbalancing choice references "node", the addresses' parameters are used to make the loadbalancing choice rather than the member's parameters.
C. When the loadbalancing choice references "node", priority group activation is unavailable.
D. There is no difference; the two terms are referenced for backward compatibility purposes.
正解：C

質問 8：
Refer to the exhibit.


A BIG-IP Administrator creates a new Virtual Server to load balance SSH traffic. Users are unable to log on to the servers.
What should the BIG-IP Administrator do to resolve the issue?
A. Set Protocol to UDP
B. Set Source Address to 10.1.1.2
C. Set HTTP Profile to None
D. Set Destination Addresses/Mask to 0.0.0.0/0
正解：C
