A pool member is receiving fewer connections than expected, even though it is healthy and the load balancing method is round-robin. Which configuration is most likely preventing the BIG-IP from sending more connections to that member?

A persistence profile configured on the virtual server

A connection limit configured on the pool member

A priority group activation threshold set to 1

A health monitor that is not configured

A BIG-IP administrator is configuring a pool with two priority groups. Group 1 has 3 members, and Group 2 has 2 members. The administrator sets the priority group activation to 'Less than 2'. The administrator wants to ensure that Group 2 is used only when Group 1 has fewer than 2 available members. Which of the following scenarios would cause Group 2 to receive traffic?

One Group 1 member has reached its connection limit

A BIG-IP administrator is configuring a pool with two priority groups. Group 1 has 4 members, and Group 2 has 2 members. The administrator sets the priority group activation to 'Less than 3'. The administrator notices that Group 2 is receiving traffic even though all 4 Group 1 members are healthy. What is the most likely explanation?

The load balancing method is set to Ratio, overriding the priority group settings

The monitor for Group 1 members is failing intermittently

The Group 1 members have reached their connection limits, making them unavailable

The Group 2 members have a higher priority than the Group 1 members

A load balancer is configured with a round-robin load balancing method, but all new connections from a single client are being sent to the same pool member. Which persistence mechanism is most likely causing this behavior?

Destination address persistence

A company uses a BIG-IP to load balance an HTTP application. The virtual server uses cookie persistence. Users are reporting that they are being logged out frequently and sent to different servers. The administrator checks the cookie persistence profile and sees that the 'Expiration' setting is set to 'Session'. What is the most likely cause of the frequent logouts?

The session cookie is deleted when the browser closes, so users are load balanced to a different server on their next visit

The load balancing method is set to Least Connections, overriding the persistence profile

The pool members are failing over frequently

The cookie persistence profile is set to 'Rewrite' mode, which does not preserve the cookie
