An LTM Specialist is configuring a new virtual server on an LTM device and assigning a SNAT pool that is already is use another virtual server. Both virtual servers use the same pool members to load balance traffic. A maximum of 35,000 users needs to be able to access each virtual server ta any time. The network architecture does NOT allow the backend servers to use the LTM device as a default gateway.
What is the minimum number of SNAT addresses required in the SNAT pool to meet the needs of the virtual servers?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: C
Explanation:
Both vs share the same snat pool, and both use the same pool member. Then the concurrent number of snatpool will be added. For each VS, there is a maximum of 35,000 users, and those two VSs have a maximum of 70,000 users. The stem did not mention how many connections each user would have concurrently. Calculated with a minimum of 1 connection, then 70,000 connections would be concurrent. One IP can support 65,535 connection. Therefore, at least 2 or more snaptips are required
