문제3

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 load-balancing mode is most effective if the goal is to maintain a relatively even load across all servers?

A. Priority

B. Observed

C. Ratio

D. Round Robin

정답: B

문제4

A virtual server is listening at 10.10.1.100:any and has the following iRule associated with it: when CLIENT_ACCEPTED { if {[TCP::local_port] equals 80 } { pool pool1 } elseif {[TCP::local_port] equals 443 } { pool pool2 } If a user connects to 10.10.1.100 and port 22, which pool will receive the request?

A. pool2

B. None. The request will be dropped.

C. pool1

D. Unknown. The pool cannot be determined from the information provided.

정답: D

문제5

A virtual server at 10.10.1.100:80 has the rule listed below applied. When HTTP_REQUEST { if {[HTTP::uri] ends_with "htm" } { pool pool1 } elseif {[HTTP::uri] ends_with "xt" } { pool pool2 } If a user connects to http://10.10.1.100/foo.txt which pool will receive the request?

A. pool2

B. None. The request will be dropped.

C. pool1

D. Unknown. The pool cannot be determined from the information provided.

정답: A

문제6

Which statement is true concerning a functional iRule?

A. iRules must contain at least one event declaration.

B. iRules must contain at least one pool assignment statement.

C. iRules must contain at least one conditional statement.

D. iRules use a proprietary syntax language.

정답: A

문제7

Which statement is true concerning cookie persistence?

A. Cookie persistence allows persistence independent of IP addresses.

B. Cookie persistence uses a cookie that stores the virtual server, pool name, and member IP address in clear text.

C. Cookie persistence allows persistence even if the data are encrypted from client to pool member.

D. If a client's browser accepts cookies, cookie persistence will always cause a cookie to be written to the client's file system.

정답: A

문제8

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

A. All open connections will be lost.

B. Long-lived connections such as Telnet and FTP will be maintained while short-lived connections such as HTTP will be lost.

C. All open connections are lost, but new connections are initiated by the newly active BIG-IP, resulting in minimal client downtime.

D. All open connections will be maintained.

E. The "Mirror" option must be chosen on the NAT and the setting synchronized prior to the connection establishment.

정답: D

문제9

Where is persistence mirroring configured?

A. It is part of a pool definition.

B. It is part of a virtual server definition.

C. It is part of a profile definition.

D. It is always enabled.

정답: C

문제10

Generally speaking, should the monitor templates be used as production monitors or should they be customized prior to use?

A. Monitor template customization is only a matter of preference, not an issue of effectiveness or performance.

B. Most templates, such as http and tcp, are as effective as customized monitors.

C. Most templates, such as https, should have the receive rule customized to make the monitor more robust.

D. While some templates, such as ftp, must be customized, those that can be used without modification are not improved by specific changes.
