What does a persistence record typically contain?

The virtual server's configuration

A mapping between a client identifier and a specific pool member

The client's full browsing history

The load-balancing algorithm in use

After a fallback occurs because the persisted pool member is down, what happens to the persistence record?

It is moved to a different virtual server

It remains unchanged, pointing to the down member

It is updated to point to the new pool member

What happens if the pool member associated with a persistence record becomes unavailable?

The request is dropped because the persisted member is down

The request is sent to the same member anyway

The BIG-IP selects a new pool member using the load-balancing algorithm and updates the persistence record

What happens when an incoming request does not match any existing persistence record?

The request is sent to the pool member with the least connections

The request is dropped because persistence is required

The request is sent to the first pool member in the list

The BIG-IP applies the load-balancing algorithm to select a pool member and creates a new persistence record

A virtual server uses cookie persistence. A client's HTTP request arrives with a valid persistence cookie that references pool member 192.168.1.20. The BIG-IP performs a health check and determines that 192.168.1.20 is down. What will the BIG-IP do with this request?

Wait for 192.168.1.20 to recover before forwarding the request

Reject the request with a 503 Service Unavailable error

Select a new pool member using the load balancing algorithm and update the cookie

Send the request to 192.168.1.20 anyway because persistence is absolute

Part of the Determine expected traffic behavior based on configuration domain, which makes up ~26% of our current practice bank. F5 does not publish an official question count, but from its 30-minute exam (~10–20 total, ~3–5 in this domain), expect 1–1 from this objective — we provide 23 practice questions to prepare you well beyond it.
