A. rule(s)
B. profile(s)
C. monitor(s)
D. persistence type
E. load-balancing method

Question 7.
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 method is effective if the goal is to maintain a relatively event load across all servers?

A. Priority
B. Observed
C. Round Robin
D. Ration Member

Answer: B

Priority is not a load balancing method. Observed is the best answer, since round robin and ratio load balance without regard to system performance.

Question 8.
Which statement accurately describes the relation between the two load-balancing modes specified as "member" and "node"?

A. There is no difference; the two terms are referenced for backward compatibility purposes.
B. When the load-balancing choice references "node", priority group activation is unavailable.
C. Load-balancing options referencing "nodes" are available only when the pool members are 
    defined for the "any" port.
D. When the load-balancing choice references "node', the address' parameters are used to make  
    the load-balancing choice rather than the member's parameters.

Answer: D

Nodes have only an IP address and may represent multiple pool members while pool members always have an IP address and service port designation.

Question 9.
A load-balancing 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 whether the traffic is between the BIG-IP and client or the 
    BIG-IP and server.
B. The server IP address is unchanged whether the traffic is between the BIG-IP and client or the 
    BIG-IP and server
C. The TCP port used in the client to BIG-Ip connection are the same as the TCP ports in the
    BIG-IP to server connection
D. The IP addresses used in the client to big-IP connection are the IP addresses in the BIG-IP to 
    server connection.

Answer: A
