F5 Networks F5CAB5 Exam - Topic 3 Question 4 Discussion

Actual exam question for F5 Networks's F5CAB5 exam

Question #: 4
Topic #: 3

A BIG-IP Administrator receives reports from users that SSL connections to the BIG-IP device are failing. Upon checking the log files, the administrator notices: SSL transaction (TPS) rate limit reached. stats show a maximum of 1200 client-side SSL TPS and 800 server-side SSL TPS. What is the minimum SSL license limit required to handle this peak?

A2000

B400

C800

D1200

Show Suggested Answer

Suggested Answer: D

Troubleshooting failed SSL handshakes involves interpreting the resource limits defined by the system's license8888. The log message SSL transaction (TPS) rate limit reached indicates the BIG-IP is dropping SSL connections because it has exceeded its licensed 'Transactions Per Second' capacity. When analyzing stats to determine the correct license level, the administrator must focus on 'Client-side' SSL TPS. This represents the initial encrypted handshakes between users and the BIG-IP virtual servers91. In this scenario, the peak client-side demand is 1200 TPS. While the 800 server-side transactions represent re-encryption toward the backend, F5's primary SSL TPS license limits typically apply to the client-facing side of the traffic flow. Therefore, to resolve the intermittent connectivity issues and ensure the virtual server works reliably during peaks, the license must be upgraded to at least 1200 TPS949596969696. 9798Confirming this peak via statistics and comparing it to the current license is a standard troubleshooting step for SSL performance issues.

Wow, this question is a real brain-teaser! I'm going to go with the answer that involves the most math - A) 2000. That way, I can show off my advanced problem-solving skills to the exam graders.

C) 800 is the answer. The question clearly states the server-side SSL TPS is 800, so that should be the minimum SSL license limit required.

B) 400 is the way to go. The question is asking for the minimum SSL license limit, and the server-side SSL TPS is only 800, so 400 should be enough.

D) 1200 seems like the right answer to me. The question only mentions the maximum client-side SSL TPS, so that should be the minimum SSL license limit required.

A) 2000 is the correct answer. The question states that the maximum client-side SSL TPS is 1200 and the maximum server-side SSL TPS is 800, so the minimum SSL license limit required would be the sum of these two, which is 2000.

From what I studied, the minimum license should cover the peak TPS, so I guess we should go with the higher of the two numbers, which is 1200.

I practiced a similar question where we had to determine license limits based on peak usage, but I can't recall if we always add them or take the higher one.

I think we need to consider both client-side and server-side TPS. If the max is 1200 for client and 800 for server, wouldn't we just add those together?

I remember something about calculating SSL TPS limits, but I'm not entirely sure how to add them up for the license requirement.

Alright, I'm feeling pretty confident about this one. The key is to add the client-side and server-side SSL TPS to get the total, which is 1200 + 800 = 2000. So the minimum SSL license limit required is option A) 2000.

I think I've got this. The question is asking for the minimum SSL license limit required to handle the peak SSL TPS, which is the sum of the client-side and server-side SSL TPS. So the answer should be 2000.

I'm a bit confused. Does the question mean the minimum SSL license limit required to handle the peak, or the total SSL TPS? I want to make sure I understand what I'm being asked to calculate.

Okay, let's see. The question is asking for the minimum SSL license limit required, and it's giving us the maximum client-side and server-side SSL TPS. I think I need to add those two numbers together to get the total SSL TPS.

Hmm, this seems like a tricky one. I'll need to carefully review the information provided and think through the calculations.
