101 Exam - Question 79


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?

Show Answer
Correct Answer: CD

When comparing source address persistence profiles with different subnet masks, the profile with the larger subnet mask (i.e., one comprising more bits) will identify a larger number of unique addresses. Profile A with a mask of 255.255.255.0 narrows down the persistence records to clients within a tighter subnet, whereas Profile B with a mask of 255.255.0.0 broadens the range, accommodating a greater pool of clients. Hence, Profile B has a greater potential number of persistence records.
