NEW QUESTION 18
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. 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.... - B. Increase the receive window of the client-side TCP profile
- C. Increase the proxy buffer high setting on the server-side TCP profile
- D. Reduce the proxy buffer high setting on the server-side TCP profile
Answer: D
NEW QUESTION 19
An LTM Specialist needs to force only FTP traffic, sourced from subnet 10.10.10.0/24 to virtual server 10.10.20.1 to the new FTP1 server. The following virtual servers are configured on the LTM device:
Traffic sourced from 10.10.10/24 must use the specific pool member for load balancing.
Which configuration change is needed to meet the requirements?
- A. Create a new virtual server for traffic sourced from 10.10.10.0/24 on traffic sourced from 10.10.10./24 on port 21 that is destined to 10.10.20.1/32, and create a new pool that has only the pool member FTP1 defined.
- B. Create a new virtual server for traffic sourced from 10.10.10.0/24 on port 80 that is destined to 10.10.20.1/32, and create a new pool has only the pool member FTP1 defined.
- C. Add FTP1 to the pool assigned to the MyVS2 virtual server, and remove all other pool member from the pool.
- D. Add FTP1 to the pool assigned to the MyVS4 virtual server, and remove all other pool members from the pool.
Answer: C
Explanation:
According to the VS matching order, first match the destination host IP, then match the destination port and finally match the source network segment. In the current network configuration, 10.10.10./24 access to 10.10.10.20.1 will hit MyVS2. If there is no error in the title, subnet 10.10.10.0 to virtual Server 10.10.20.1 to the FTP1 server,'' Is to distribute all traffic from 10.10.10.1 to FTP1, then D That's right.

- D. set the Send String to GET/ status html and the Receive String to 200 and Receive Disable String to 201.
Answer: A
NEW QUESTION 21
An application is being load balanced through the LTM device using the configuration displayed below.
The network has been re-engineered to NAT all client connection. As a result, all client connections are hitting the same pool member.
Which changes should the LTM Specialist make in order to restore load balancing functionality wile maintaining session persistence?
- A. Leave the virtual server type set Performance (Layer 4) and change the persistence type to hash
- B. Change the virtual server type to Standard, add an http profile, and change the persistence profile to Destination Address
- C. Change the virtual serer type to Forwarding (Layer 4) and leave the persistence type to hash source Address
- D. Change the virtual server to Standard add an http profile, and change the persistence profile to Cookie persistence
Answer: D
NEW QUESTION 22
Refer to the following iRule:
What is a complete list of profiles that must be applied to the virtual server for this iRule?
- A. TCP, HTTP
- B. Fast L4, HTTP
- C. TCP, HTTP, Client SSL
- D. Fast L4 , HTTP, Stream
Answer: A
NEW QUESTION 23
An LTM Specialist needs to create an iRule that creates persistence records based on a JSESSIONID cookie. If a persistence record already exists, then the iRule must persist the client connection according to the existing record.
Which persistence profile enables the iRule to meet these requirements?
- A. Destination Address Affinity
- B. SSL
- C. Universal
- D. Cookie
- E. Source Address Affinity
Answer: C
NEW QUESTION 24
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
