What is the primary role of an inactive ADC element in a BIG-IP system?

To process traffic when the active element is overloaded.

To provide a backup that can take over traffic processing if the active element fails.

To continuously monitor and log all traffic passing through the active element.

To hold configuration changes until the active element is ready to apply them.

A BIG-IP system has a virtual server with two pools: PoolA (active) and PoolB (backup). PoolA contains two healthy pool members. A network engineer observes that traffic is being load-balanced across both PoolA members. Which ADC element is actively processing the traffic in this scenario?

The default persistence profile

In a BIG-IP system, which component is actively processing traffic when a client request is being load-balanced to a pool member?

The configuration utility (tmsh)

The standby unit in a device group

The virtual server and the selected pool member

A BIG-IP has a virtual server with a pool of two members. Member1 is healthy and enabled. Member2 is healthy but disabled. The administrator needs to perform maintenance on Member1 and wants to ensure zero downtime. What is the most appropriate action to take?

Disable the virtual server and then enable Member2

Enable Member2 before disabling Member1

Disable Member1 and then enable Member2

Change the load-balancing method to 'Priority'

An administrator is reviewing the configuration of a BIG-IP. They see a virtual server with a pool that has a 'fallback host' configured. The pool has one healthy member. What is the role of the fallback host in this configuration?

It is an inactive element that only receives traffic if the pool becomes unavailable

It is a monitoring target for the pool members

It is a backup pool that is used for failover

It is an active element that receives a portion of the traffic
