201 Online Practice Questions and Answers

A standard virtual server is defined with a pool and a SNAT using automap. All other settings for the virtual server are at defaults. When client traffic is processed by the BIG-IP, what will occur to the IP addresses?

A. Traffic initiated by the pool members will have the source address translated to a self-IP address but the destination address will not be changed.

B. Traffic initiated to the virtual server will have the destination address translated to a pool member address and the source address translated to a self-IP address.

C. Traffic initiated by selected clients, based on their IP address, will have the source address translated to a self-IP address but the destination will only be translated if the traffic is destined to the virtual server.

D. Traffic initiated to the virtual server will have the destination address translated to a pool member address and the source address translated to a self-IP address. Traffic arriving destined to other destinations will have the source translated to a self-IP address only.

If a client's browser does not accept cookies, what occurs when the client connects to a virtual server using cookie persistence?

A. The connection request is not processed.

B. The connection request is sent to a pology server.

C. The connection request is loadbalanced to an available pool member.

D. The connection request is refused and the client is sent a "server not available" message.

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.

C. iRules can examine a server 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

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 } else if {[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.

Which statement is true regarding failover?

A. Hardware failover is disabled by default.

B. Hardware failover can be used in conjunction with network failover.

C. If the hardware failover cable is disconnected, both BIGIP devices will always assume the active role.

D. By default, hardware fail over detects voltage across the failover cable and monitors traffic across the internal VLAN.

How should a BIG-IP Administrator persistent sessions from being sent to a pool member so that the server administrator can perform maintenance?

A. force the pool member offline

B. disable the pool member

C. add an additional monitor to the poor

D. disable the virtual server

Which IP address will the client address be changed to when SNAT automap is specified within a Virtual Server configuration?

A. The floating self-IP address on the VLAN where the packet leaves the system.

B. The floating self-IP address on the VLAN where the packet arrives on the system.

C. It will alternate between the floating and non floating self-IP address on the VLAN where the packet leaves the system so that port exhaustion is avoided.

D. It will alternate between the floating and non floating self-IP address on the VLAN where the packet arrives on the system so that port exhaustion is avoided.

Refer to the exhibit.
