質問 34
An LTM Specialist is configuring a client profile to offload processing a new application Company policy requires that clients can resume session for up to 30 minutes, but must renegotiate a new session after that.
Which setting should the LTM Specialist change to satisfy this requirement?
- A. Renegotiation period
- B. Renegotiate Max Record Delay
- C. Cache size
- D. Cache timeout
正解: D
解説:
Question stem requires that you can resume SSL session within 30 minutes, then you need to define the ssl cache time in 30 minutes
質問 35
AN LTM Specialist is deploying an iRule designed to determine the country of origin of an incoming client connection. The iRule needs to be used with an SSL-enabled web application.
Which profile required for the iRule to function properly?
- A. HTTP
- B. UDP
- C. TCP
- D. DNS
正解: C
解説:
Question stem requires the client IP to match the source region, so TCP ?UDP at the transport layer can meet the requirements. The title stem mentions that it is a Web application based on SSL, and it does not mention F5 undertakes SSL offload, So TCP is enough.
質問 36

What is a potential result of this action?
- A. IP conflict result
- B. HTTP traffic is NOT allowed
- C. Other service ports could be allowed
- D. Packet filter allowances are also required
正解: B
質問 37

質問 41
An LTM Specialist upgrades the switching infrastructure and the backend servers on the LAN segments.
The LTM Specialist notices a 20% memory usage increase on the BIG-IP device while handling the same number of concurrent connections.
A comparison of statistics pre-upgrade and post-upgrade shows a significant reduction on the following:
-RTT between the BIG-IP device and the backend servers
-Packet drops in the switch
Time to First Byte (TTFB)
The LTM Specialist is concerned with the scalability of the number of concurrent connections with the new memory usage.
Which setting should be changed to reduce the memory usage on the BIG-IP device?
- A. Increase the proxy buffer high setting on the server-side TCP profile
- B. Reduce the proxy buffer high setting on the server-side TCP profile
- C. Increase the receive window of the client-side TCP profile
- D. Reduce the idle of the client-side TCP profile
Explanation
After adjusting the architecture, the network quality becomes better. With the connection unchanged the memory usage increase by 20%. It means that the sending speed of the server is higher than the receiving speed of the client. F5 caches more content on the memory and causes the memory usage to....
正解: B
