F5 Application Delivery Fundamentals — Question 107

What is the expected difference between two source address persistence profiles if profile A has a mask of 255.255.255.0 and profile B has a mask of
255.255.0.0?

Answer options

• A. Profile A will have more clients matching existing persistence records.
• B. There are no detectable differences.
• C. Profile B has a greater potential number of persistence records.
• D. Profile B will have fewer persistence records for the sane client base.

Correct answer: D

Explanation

Profile A, with a more specific mask of 255.255.255.0, allows for better granularity and hence can match more individual clients, leading to more persistence records. In contrast, profile B's broader mask of 255.255.0.0 encompasses a larger range of IPs, but does not differentiate among them as effectively, resulting in fewer persistence records for the same set of clients.
