問題 #22
Which two types of reports does iostat generate?

A. CPU Utilization Report
B. Device Utilization Report
C. Memory Utilization Report
D. Swap Utilization Report
E. Storage Utilization Report

答案：A,B

解題說明：
Explanation of Answer B:iostatis a tool used to monitor system input/output device loading by observing the time devices are active concerning their average transfer rates. The "Device Utilization Report" provides statistics about device utilization and throughput rates, which is critical in identifying performance bottlenecks.
Explanation of Answer E:iostatalso generates "CPU Utilization Reports." These reports provide data about how the CPU is utilized during input/output operations, showing the percentage of CPU time used for user processes, system processes, and the time the CPU remains idle.

問題 #23
Examine this command:
# cryptsetup luksOpen /dev/xvdd1 cryptfs
What happens upon execution?

A. It creates the LUKS partition on /dev/xvdd1.
B. It creates the /dev/mapper/cryptfs device mapping file.
C. It creates the /dev/mapper/xvdd1/cryptfs device mapping file.
D. It creates the /dev/mapper/xvdd1 device mapping file.
E. It creates the /dev/mapper/xvdd1-cryptfs device mapping file.

答案：B

解題說明：
The commandcryptsetup luksOpen /dev/xvdd1 cryptfsis used to open an encrypted LUKS partition. This command maps the encrypted block device/dev/xvdd1to a decrypted block device that is accessible under/dev
/mapper/cryptfs.
* Option A (Correct):This is correct because thecryptsetup luksOpencommand creates a device mapping under/dev/mapper/with the name specified (cryptfsin this case). This mapping allows you to access the encrypted content of/dev/xvdd1through the decrypted virtual device/dev/mapper/cryptfs.
* Options B, C, D, E (Incorrect):These options are incorrect because they do not accurately reflect the standard behavior of thecryptsetup luksOpencommand. The device created will always be in the format
/dev/mapper/<name>where<name>is the alias specified in the command.
Oracle Linux Reference:For more information, refer to:
* OracleLinux 8: Managing Storage Devices
* man cryptsetupfor more details on theluksOpencommand and LUKS management.
