The following iRule is being used within a persistence profile on a virtual server. Assuming the following HTTP requests are made within the same timeout window, what is the maximum number of persiste

The 'persist uie' command creates one persistence record per unique key value, and the key is derived by 'findstr [HTTP::uri] "?" 8 3', which skips 8 characters after the '?' and captures the next 3 characters. Because the given HTTP requests within the same timeout window yield exactly 4 distinct 3-character substrings, at most 4 separate UIE persistence records are created - one per unique extracted key.

3 records underestimates the result because the given request set contains 4 unique URI substrings that each map to a distinct persistence key.

10 records is too high and would require 10 unique 3-character substrings across the provided requests, which exceeds what the data supports.

The maximum is determinable from the listed requests by extracting and counting unique 3-character substrings at the specified offset, so the answer is not indeterminate.

5 records exceeds the number of unique key values extractable from the provided request URIs based on the iRule's extraction logic.

1 record would only occur if all provided requests produced the same 3-character substring at the specified position, which contradicts the given data.

0 records would require the iRule to never fire or always produce an empty key, but valid HTTP_REQUEST events with qualifying URIs will produce non-empty persistence keys.
