BIG-IP matches virtual servers based on specificity:

Exact match IP + port → highest priority

Exact IP, any port → next

Any IP, specific port → next

Any IP, any port → lowest priority

Step 4: Apply the rules to this case

Traffic: 1.1.1.1:8080

Matches:

host_8080_vs → IP = 1.1.1.1, Port = 8080 ✅ exact match

fwd_8080_vs → IP = any, Port = 8080 ✅ less specific

Other VS → less specific

Most specific match wins → host_8080_vs

✅ Answer:

B. host_8080_vs

BIG-IP uses a specific order of preference when selecting which virtual server should process a connection. From most preferred to least preferred, the order is:
- Destination host address (most specific match)
- Source host address
- Service port (least preferred)

host_8080_vs → IP = 1.1.1.0/24, Port = 8080
host_vs → IP = 1.1.1.1, Port = 0
Based on the order of preference, C. host_vs is the correct answer because it has a destination 1.1.1.1 while host_8080_vs has 1.1.1.0/24.
