A site would like to ensure that a given web server's default page is being served correctly prior to sending it client traffic. They assigned the A site would like to ensure that a given web server's default page is being served correctly prior to sending it client traffic. They are assigned the default HTTP monitor to the pool. What would the member status be if it sent an unexpected response to the GET request default HTTP monitor to the pool. What would the member's status be if it sent an unexpected response to the GET request?

A. The pool member would be marked offline (red).

B. The pool member would be marked online (green).

C. The pool member would be marked unknown (blue).

D. The pool member would alternate between red and green.

A site wishes to perform source address translation on packets arriving from the Internet for clients using some pools but not others. The determination is not based on the client's IP address, but on the pool they are load balanced to. What could best accomplish this goal?

A. A SNAT for all addresses could be defined, and then disable the SNAT processing for select pools.

B. The decision to perform source address translation is always based on VLAN. Thus, the goal cannot be achieved.

C. For each virtual server, regardless their default load balancing pools, association with SNAT pools could vary dependent upon need.

D. The decision to perform source address translation is always based on a client's address (or network). Thus, this goal cannot be achieved.

Which statement describes a typical purpose of iRules?

A. iRules can be used to add individual control characters to an HTTP data stream.

B. iRules can be used to update the timers on monitors as a server load changes.iRules can be used to update the timers on monitors as a server's load changes.

C. iRules can examine a server response and remove it from a pool if the response is unexpected iRules can examine a server's response and remove it from a pool if the response is unexpected.

D. iRules can be used to look at client requests and server responses to choose a pool member to select for load balancing.

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

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

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

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

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.

You have created a custom profile named TEST2. The parent profile of TEST2 is named TEST1. If additional changes are made to TEST1, what is the effect on TEST2?

A. All changes to TEST1 are propagated to TEST2.

B. Some of the changes to TEST1 may propagate to TEST2.

C. Changes to TEST1 cannot affect TEST2 once TEST2 is saved.

D. When TEST1 is changed, the administrator is prompted and can choose whether to propagate changes to TEST2.

The incoming client IP address is 195.64.45.52 and the last five connections have been sent to members A, C, E, D and B. Given the virtual server, pool, and persistence definitions and statistics shown in the above graphic, which member will be used for the next connection?

A. 10.10.20.1:80

B. 10.10.20.2:80

C. 10.10.20.3:80

D. 10.10.20.4:80

E. 10.10.20.5:80

F. It cannot be determined with the information given.

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. pool1

B. pool2

C. None. The request will be dropped.

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

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.

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.
