“Block responses” / “Silently discard” → DROP

Step 1: Understand the types

A. Drop VS

A Drop virtual server silently drops traffic—no response is sent to the client.

This is often used to block traffic from a specific IP or subnet. ✅

B. Block VS

“Block” is not an actual BIG-IP virtual server type. ❌

C. Reject VS

A Reject virtual server sends a TCP RST or ICMP unreachable to the client.

This actively informs the client that traffic is blocked. ❌ (less stealthy than Drop)

D. Standard VS

A standard virtual server forwards traffic to a pool; it doesn’t block traffic. ❌

Step 2: Apply the requirement

Requirement: block responses for one IP → we want traffic silently dropped.

✅ That is exactly what a Drop virtual server does.

✅ Answer:

A. Drop
