Hackers recently targeted a company with an attack that resulted in a system breach, which compromised the organization's dat a. Because of the system breach, the administrator had to bypass normal change management procedures. Which of the following change management activities was necessary?
- A. Emergency change request
- B. User permission change request
- C. Cancelled change request
- D. Privilege change request
- E. Change request postponement
正解：A
解説：
An emergency change request is a type of change request that is initiated in response to an urgent situation, such as a system breach, that requires immediate action to restore normal operations or prevent further damage. An emergency change request may bypass some of the normal change management procedures, such as approval, testing, or documentation, in order to expedite the implementation of the change. However, an emergency change request should still follow the basic steps of change management, such as identification, analysis, planning, execution, and evaluation, and should be reviewed and documented after the change is completed.

質問 # 154
After a technician upgrades the firmware on a database server that is connected to two external storage arrays, the server prompts the technician to configure RAID. The technician knows the server had several configured RAID sets and thinks the firmware upgrade cleared the RAID configurations. Which of the following should the technician do to troubleshoot this issue?
- A. Perform a rescan on the server's RAID controller.
- B. Restore the default RAID configuration and reboot.
- C. Power cycle the storage arrays and rescan RAID on the server.
- D. Boot the OS into recovery mode and rescan the disks.
正解：A
解説：
Explanation
A rescan on the server's RAID controller is a possible troubleshooting step to detect the existing RAID configurations on the connected storage arrays. A firmware upgrade may cause the RAID controller to lose the RAID metadata or settings, and a rescan may restore them. A rescan is preferable to restoring the default RAID configuration, as the latter may erase the existing data on the arrays. Power cycling the storage arrays or booting the OS into recovery mode may not help if the RAID controller does not recognize the RAID sets.

質問 # 155
A server administrator is trying to determine the cause of a slowdown on a database server. Upon investigation, the administrator determines the issue is in the storage subsystem. Which of the following will most likely resolve this issue?
- A. Extending capacity by installing a 4TB SATA disk
- B. Increasing IOPS by implementing flash storage
- C. Implementing deduplication on the storage
- D. Reformatting the disk as FAT32
正解：B
解説：
Explanation
Increasing IOPS (input/output operations per second) by implementing flash storage is the most likely solution to resolve a slowdown issue in the storage subsystem of a database server. Flash storage uses solid-state drives (SSDs) that have faster read/write speeds and lower latency than traditional hard disk drives (HDDs). This can improve the performance of database queries and transactions. Implementing deduplication, extending capacity, or reformatting the disk as FAT32 are not likely to resolve the issue, as they do not affect the IOPS of the storage subsystem.

- A. Crash cart
- B. RDP
- C. IP KVM
- D. Out-of-band console
正解：D
解説：
Out-of-band console is a tool that can be used to command a remote shutdown of a physical Linux server.
Out-of-band console is a method of accessing a server's console through a dedicated management port or device that does not rely on the server's operating system or network connection. Out-of-band console can be used to power cycle, reboot, update firmware, monitor performance, and perform other tasks remotely even if the server is unresponsive or offline. Crash cart is a mobile unit that contains a keyboard, monitor, mouse, and other tools that can be used to troubleshoot a server on-site, but it requires physical access to the server. IP KVM (Internet Protocol Keyboard Video Mouse) switch is a hardware device that allows remote access to multiple servers using a web browser or a client software, but it requires network connectivity and may not work if the SSH connection is lost. RDP (Remote Desktop Protocol) is a protocol that allows remote access to a Windows server's graphical user interface, but it does not work on Linux servers and requires network connectivity.

An organization stores backup tapes of its servers at cold sites. The organization wants to ensure the tapes are properly maintained and usable during a DR scenario. Which of the following actions should the organization perform?
- A. Have duplicate equipment available at the cold site.
- B. Retrieve the tapes from the cold site and test them.
- C. Use the test equipment at the cold site to read the tapes.
- D. Have the facility inspect and inventory the tapes on a regular basis.
正解：B
解説：
Explanation
The organization should retrieve the tapes from the cold site and test them to ensure they are properly maintained and usable during a DR scenario. A cold site is a location that has space and power for backup equipment, but no actual equipment installed or configured. The organization stores backup tapes of its servers at cold sites as a precaution in case of a disaster that affects its primary site. However, backup tapes can degrade over time due to environmental factors such as temperature, humidity, dust, or magnetic fields.
Therefore, the organization should periodically retrieve the tapes from the cold site and test them on compatible equipment to verify their integrity and readability.
