A site has six members in a pool. Three of the servers are new and have more memory and a faster processor than the others. Assuming all other factors are equal and traffic should be sent to all members, which two load-balancing methods are most appropriate? (Choose two.)

A. Ratio

B. Priority

C. Observed

D. Round Robin

A standard virtual server has been associated with a pool with multiple members. Assuming all other settings are left at their defaults, which statement is always true concerning traffic processed by the virtual server?

A. The client IP address is unchanged between the client-side connection and the server-side connection.

B. The server IP address is unchanged between the client-side connection and the server-side connection.

C. The TCP ports used in the client-side connection are the same as the TCP ports server-side connection.

D. The IP addresses used in the client-side connection are the same as the IP addresses used in the server-side connection.

Monitors can be assigned to which three resources? (Choose three.)

A. NATs

B. pools

C. iRules

D. nodes

E. SNATs

F. pool members

G. virtual servers

Assume a virtual server has a ServerSSL profile. What SSL certificates are required on the pool members?

A. No SSL certificates are required on the pool members.

B. The pool members?SSL certificates must only exist.

C. The pool members?SSL certificates must be issued from a certificate authority.

D. The pool members?SSL certificates must be created within the company hosting the BIG-IPs.

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.

Assume a client's traffic is being processed only by a NAT; no SNAT or virtual server processing takes place. Also assume that the NAT definition specifies a NAT address and an origin address while all other settings are left at their defaults. If a client were to initiate traffic to the NAT address, what changes, if any, would take place when the BIG-IP processes such packets?

A. The source address would not change, but the destination address would be translated to the origin address.

B. The destination address would not change, but the source address would be translated to the origin address.

C. The source address would not change, but the destination address would be translated to the NAT's address.

D. The destination address would not change, but the source address would be translated to the NAT's address.

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.

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.

A virtual server is listening at 10.10.1.100:80 and has the following iRule associated with it: when HTTP_REQUEST { if {[HTTP::uri] ends_with "txt" } { pool pool1 } elseif {[HTTP::uri] ends_with "php" } { pool pool2 } If a user connects to http://10.10.1.100/foo.html, 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 that systems are synchronized, which action could take place if the fail-over cable is connected correctly and working properly, but the systems cannot communicate over the network due to external network problems?

A. If network fail-over is enabled, the standby system will assume the active mode.

B. Whether or not network fail-over is enabled, the standby system will stay in standby mode.

C. Whether or not network fail-over is enabled, the standby system will assume the active mode.

D. If network fail-over is enabled, the standby system will go into active mode but only until the network recovers.
