NO.85 Which single command simulates a failed device within a RAID 5 array?

NO.86 How is the source code for the main Linux kernel modules distributed?

NO.87 CORRECT TEXT

NO.90 A web application server contains 64GB of RAM and two swap partitions on normal hard disk drives, each with a size of 64 GB.

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.)
