BIG-IP LTM Specialist: Architect Set-Up & Deploy Questions and Answers

Question 1

An LTM device provides load balancing to a web application? The LTM device has two dual-core processors and a licensed SSL Transactions Per Second (TPS) limit of 500 CMP is enabled.

TLS connections are used between client systems and virtual servers on the LTM device, as well as from the LTM device to servers used as part of LTM pool.

During a peak period. 2560 new TLS transactions per second are attempted to the web application via the LTM device.

What will happen in this scenario?

A.

560 new TLS transactions will be silently discarded due to the SSL TPS license limit

B.

Nothing: TLS transactions per second are NOT affected by an SSL TPS license limit
