Palo Alto Networks SSE Engineer — Question 5

Which two statements apply when a customer has a large branch office with employees who all arrive and log in within a five-minute time period? (Choose two.)

Answer options

• A. DNS results are only cached for frequently used hostnames.
• B. Maximum pending TCP DNS requests is 64.
• C. Maximum number of TCP DNS retries is 3.
• D. DNS results are cached for 300 seconds.

Correct answer: B, D

Explanation

Option B is correct because the maximum number of pending TCP DNS requests is indeed 64, which can impact performance during peak login times. Option D is also correct as DNS results are cached for 300 seconds, improving efficiency. Options A and C are not directly related to the immediate login scenario and do not address the question's focus on simultaneous logins.
