質問 # 96
Which of the following ensures a secondary network path is available if the primary connection fails?
- A. Most recently used
- B. Fault tolerance
- C. Link aggregation
- D. Heartbeat
正解：B
解説：
Explanation
Fault tolerance is the ability of a system to continue functioning in the event of a failure of one or more of its components. Fault tolerance can ensure a secondary network path is available if the primary connection fails.
Fault tolerance can be achieved by using redundant components, such as network cards, cables, switches, routers, etc., that can take over the function of the failed component without interrupting the service.

質問 # 97
A server administrator is swapping out the GPU card inside a server. Which of the following actions should the administrator take FIRST?
- A. Shut down the server.
- B. Inspect the GPU that is being installed.
- C. Ensure the GPU meets HCL guidelines.
- D. Disconnect the power from the rack.
正解：A
解説：
Explanation
The first action that the administrator should take before swapping out the GPU card inside a server is to shut down the server. This is to ensure that the server is not running any processes that might be using the GPU card, and to prevent any damage to the hardware or data loss due to sudden power loss. Shutting down the server also reduces the risk of electrostatic discharge (ESD) that might harm the components. Reference:

質問 # 100
A server administrator wants to ensure a storage array can survive the failure of two drives without the loss of dat a. Which of the following RAID levels should the administrator choose?
- A. 0
- B. 1
- C. 2
- D. 3
正解：B
解説：
RAID 6 is a level of RAID that can survive the failure of two drives without the loss of data. RAID 6 uses block-level striping with two parity blocks distributed across all member disks. RAID 6 can tolerate two simultaneous drive failures and still provide data access and redundancy. RAID 0 is a level of RAID that uses striping without parity or mirroring, and offers no fault tolerance. RAID 0 cannot survive any drive failure without data loss. RAID 1 is a level of RAID that uses mirroring without parity or striping, and offers fault tolerance by duplicating data on two or more disks. RAID 1 can survive one drive failure without data loss, but not two. RAID 5 is a level of RAID that uses block-level striping with one parity block distributed across all member disks. RAID 5 can tolerate one drive failure without data loss, but not two. Reference:

質問 # 101
Users report they ate unable to access an application after a recent third-party patch update. The physical server that is hosting the application keeps crashing on reboot. Although the update was installed directly from the manufacturer's support website as recommended it has now been recalled and removed from the website as the update unintentionally installed unauthorized software after a reboot. Which of the following steps should the administrator perform to restore access to the application while minimizing downtime? (Select TWO)
- A. Enable a GPO to uninstall the update.
- B. Run a port scan to verify open ports.
- C. Uninstall recent updates.
- D. Reformat the server and restore the image from the latest backup.
- E. Scan and remove any malware.
- F. Reimage the server with a different OS.
正解：D、E
解説：
Explanation
The most likely cause of the server crashing and the application being inaccessible is that the unauthorized software installed by the update is malware that corrupted the system files or compromised the security of the server. To restore access to the application while minimizing downtime, the administrator should scan and remove any malware from the server, and then reformat the server and restore the image from the latest back-up. This will ensure that the server is clean and has a working configuration of the application. Verified References: [How to Remove Malware from a Server]
質問 # 102
A server administrator is installing a new server on a manufacturing floor. Because the server is publicly accessible, security requires the server to undergo hardware hardening. Which of the following actions should the administrator take?
- A. Close unneeded ports.
- B. Set a BIOS password.
- C. Apply driver updates.
- D. Disable unused services.
正解：B
解説：
Explanation
An action that the administrator should take to harden the hardware of a new server is to set a BIOS password.
BIOS (Basic Input/Output System) is a firmware that initializes the hardware components and settings of a system before loading the operating system. BIOS password is a security feature that requires a user to enter a password before accessing or modifying the BIOS settings or booting up the system. By setting a BIOS password, the administrator can prevent unauthorized or malicious users from changing the hardware configuration or boot order of the server.

質問 # 103
A server administrator mounted a new hard disk on a Linux system with a mount point of /newdisk. It was later determined that users were unable to create directories or files on the new mount point. Which of the following commands would successfully mount the drive with the required parameters?
- A. echo /newdisk >> /etc/fstab
- B. mount -o remount, rw /newdisk
- C. net use /newdisk
- D. mount -a
正解：B
解説：
Explanation
The administrator should use the command mount -o remount,rw /newdisk to successfully mount the drive with the required parameters. The mount command is used to mount file systems on Linux systems. The -o option specifies options for mounting file systems. The remount option re-mounts an already mounted file system with different options. The rw option mounts a file system with read-write permissions. In this case,
/newdisk is a mount point for a new hard disk that was mounted with read-only permissions by default. To allow users to create directories or files on /newdisk, the administrator needs to re-mount /

A technician re working on a Linux server and re trying to access another server over the network. The technician gets server not found message when trying to execute ping servername but no error messages when using ping servername. Domain.com. Which of the following should the technician do to resolve the error?
- A. Change the permissions on resolv. conf
- B. Modify nsswitch. Conf.
- C. Configure the domain search variable
- D. Configure the DNS address
正解：C
解説：
Explanation
The domain search variable is used to specify a list of domains that are appended to a hostname when resolving it. If the servername is not fully qualified, the resolver will try each domain in the list until it finds a match or fails. By configuring the domain search variable, the technician can avoid typing the full domain name every time they want to ping a server.

質問 # 110
A technician has been asked to check on a SAN. Upon arrival, the technician notices the red LED indicator shows a disk has failed. Which of the following should the technician do NEXT, given the disk is hot swappable?
- A. Stop sharing the volume
- B. Stop all connections to the volume
- C. Shut down the SAN
- D. Replace the disk
正解：D
解説：
The next thing that the technician should do, given the disk is hot swappable, is to replace the disk. A hot swappable disk is a disk that can be removed and replaced without shutting down the system or affecting its operation. A hot swappable disk is typically used in a storage array that has RAID (Redundant Array of Independent Disks) configuration that provides fault tolerance and redundancy. If a disk fails in a RAID array, it can be replaced by a new disk without interrupting the service or losing any data. The new disk will automatically rebuild itself using the data from the other disks in the array.
