LPIC-2 Exam 201 (Linux Engineer) — Question 24

A web application server contains 64GB of RAM and two swap partitions on normal hard disk drives, each with a size of 64 GB. Within the last month, the average number of user sessions on this server has grown by 20 percent. At the same time, the average usage of RAM increased from 65 to 75 percent, while the swap space is almost not used at all. It is expected that the number of user sessions will continue to increase by about 15 to 20 percent each month. Which of the following reactions would be appropriate in response to these observations? (Choose two.)

Answer options

• A. Delay any hardware upgrade until there is a significant consumption of swap space to ensure an efficient usage of the available hardware
• B. Create a RAID 1 device on the two swap partitions to avoid data loss in case swap space has to be used in the future
• C. Consider the installation of an additional application server to distribute the load if the expected growth continues over several months
• D. Move the web application's scripts and content a ram disk in order to ensure fast access and to avoid the need for swap space
• E. Update the hardware to increase the amount of available RAM to avoid using swap space

Correct answer: C, E

Explanation

Answer C is correct as adding an additional application server can help manage the increasing load from user sessions. Answer E is also correct since increasing RAM can prevent the need to use swap space, optimizing performance. Answers A and B are inappropriate as they do not address the immediate need for handling growing user sessions, and D, while it provides faster access, does not address the overall capacity issue.
