NEW QUESTION # 198
A technician is working on a Linux server. The customer has reported that files in the home directory are missing. The /etc/ f stab file has the following entry:
nfsserver:/home /home nfs defaults 0 0
However, a df -h /home command returns the following information:
/dev/sda2 10G 1G 9G 10% /home
Which of the following should the technician attempt FIRST to resolve the issue?
- A. umount nfsserver:/home
- B. mount /home
- C. mkdir /home
- D. rmdir nfsserver:/home/dev/sda2
Answer: A
Explanation:
The /etc/fstab file contains the information about the file systems that are mounted automatically at boot time or on demand. The entry nfsserver:/home /home nfs defaults 0 0 indicates that the /home directory on the local server is mounted from the /home directory on a remote server called nfsserver using the NFS protocol.
However, the df -h /home command shows that the /home directory is actually mounted from a local partition
/dev/sda2, which may not contain the user's files. This means that the NFS mount failed or was overridden by another mount. To resolve the issue, the technician should attempt to unmount the local partition using umount nfsserver:/home, which will detach the /home directory from /dev/sda2. Then, the technician should try to mount the NFS share again using mount /home, which will attach the /home directory to nfsserver:/home according to the /etc/fstab entry12. Creating a new directory (A) or removing an existing one would not help, as they would not affect the mount point. Mounting /home (D) without unmounting it first would not work, as it would result in an error that the mount point is busy3. References: 1

NEW QUESTION # 199
An administrator is alerted to a hardware failure in a mission-critical server. The alert states that two drives have failed. The administrator notes the drives are in different RAID 1 arrays, and both are hot-swappable.
Which of the following steps will be the MOST efficient?
- A. Shut down the server and replace the drives.
- B. Replace both failed drives at the same time.
- C. Replace one drive, wait for a rebuild, and replace the next drive.
- D. Replace all the drives in both degraded arrays.
Answer: B
Explanation:
Explanation
Since both drives are in different RAID 1 arrays and both are hot-swappable, the most efficient step is to replace both failed drives at the same time. This can minimize the downtime and avoid unnecessary reboots.
RAID 1 provides mirroring, which means that data is duplicated on both drives in the array. Therefore, replacing one drive will not affect the data on the other drive or the functionality of the array. References:

NEW QUESTION # 204
Which of the following describes a configuration in winch both nodes of a redundant system respond to service requests whenever possible?
- A. Fallback
- B. Active-passive
- C. Failover
- D. Active-active
Answer: D
Explanation:
Active-active is a configuration in which both nodes of a redundant system respond to service requests whenever possible. It can improve the performance, availability, and load balancing of the system by distributing the workload among the nodes. However, it also requires more synchronization and coordination between the nodes to avoid conflicts or errors. Verified Reference: [Active-active], [Redundant system]
NEW QUESTION # 205
An administrator notices a server is offline. Upon checking the console, the administrator discovers the server is stuck at:
Configuring Memory.............
After a reboot, the server still exhibits the same behavior. The administrator is able to log in to the OOB remote management but is unable to log in to the server. Which of the following is the most likely cause of this issue?
- A. The VRAM is insufficient
- B. A DIMM has failed
- C. The BIOS needs to be updated
- D. The RAID cache has failed
Answer: B
Explanation:
The error message "Configuring Memory..." and the fact that the server is stuck at this point strongly suggest that a DIMM (memory module) has failed. Memory issues are commonly diagnosed when servers hang during the memory configuration phase of boot.
* DIMM failure (Answer A): When a memory module fails, the server can get stuck at the memory initialization process during boot.
* VRAM insufficiency (Option B): VRAM (video memory) issues would typically cause display-related errors, not memory configuration issues.
* RAID cache failure (Option C): RAID cache issues would lead to storage errors but not prevent the system from configuring memory.
* BIOS update (Option D): While BIOS issues can cause boot failures, the error message suggests a memory-specific issue.

NEW QUESTION # 206
A technician needs to deploy an operating system that would optimize server resources. Which of the following server installation methods would BEST meet this requirement?
- A. Full
- B. Core
- C. GUI
- D. Bare metal
Answer: B
Explanation:
The server installation method that would optimize server resources is core. Core is a minimal installation option that is available for some operating systems, such as Windows Server and Linux. Core installs only the essential components and features of the operating system, without any graphical user interface (GUI) or other unnecessary services or applications. Core reduces the disk footprint, memory usage, CPU consumption, and attack surface of the server, making it more efficient and secure. Core can be managed remotely using command-line tools, PowerShell, or GUI tools.
NEW QUESTION # 207
A technician is attempting to log in to a Linux server as root but cannot remember the administrator password. Which of the following is the LEAST destructive method of resetting the administrator password?
- A. Adjust the GRUB boot parameters to boot into single-user mode. Run passwd from the command prompt.
- B. Boot using a Linux live CD and mount the hard disk to /mnt. SCP the /etc directory from a known accessible server to /mnt/etc.
- C. Boot using a Linux live CD and mount the hard disk to /mnt. Change to the /mnt/etc directory. Edit the passwd file found in that directory.
- D. Reinstall the OS in overlay mode. Reset the root password from the install GUI screen.
Answer: A
Explanation:
This is the least destructive method of resetting the administrator password because it does not require modifying any files or reinstalling the OS. It only requires changing the boot parameters temporarily and running a command to change the password. Reference: https://wiki.archlinux.org/title/Reset_lost_root_password#Using_GRUB
NEW QUESTION # 208
An organization recently experienced power outages. The administrator noticed the server did not have enough time to shut down properly. After the outages, the administrator had additional batteries installed in the UPS. Which of the following best describes the solution the administrator implemented?
- A. The solution increased power out.
- B. The solution improved load balancing,
- C. The solution extended runtime.
- D. The solution reduced shutdown time.
Answer: C
Explanation:
The solution the administrator implemented extended runtime. Runtime is the amount of time that a UPS can provide backup power to a server in case of a power outage. By installing additional batteries in the UPS, the administrator increased the capacity and duration of the backup power, allowing the server more time to shut down properly.

NEW QUESTION # 209
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. Implementing deduplication on the storage
- B. Reformatting the disk as FAT32
- C. Increasing IOPS by implementing flash storage
- D. Extending capacity by installing a 4TB SATA disk
Answer: C
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.

Storage, Objective 3.5: Summarize hardware and features of various storage technologies.
NEW QUESTION # 210
A server administrator deployed a new product that uses a non-standard port for web access on port 8443.
However, users are unable to access the new
application. The server administrator checks firewall rules and determines 8443 is allowed. Which of the following is most likely the cause of the issue?
- A. The new application's DNS entry is incorrect.
- B. Intrusion detection is blocking the port.
- C. The core switch has a network issue.
- D. The application should be changed to use port 443.
Answer: A
Explanation:
Explanation
A DNS entry is a record that maps a domain name to an IP address. If the DNS entry for the new application is incorrect, users will not be able to resolve the domain name to the correct IP address and port number. This will prevent them from accessing the application, even if the firewall rules allow port 8443. To fix this issue, the server administrator should verify and update the DNS entry for the new application.

NEW QUESTION # 211
A technician is setting up a repurposed server. The minimum requirements are 2TB while ensuring the highest performance and providing support for one drive failure. The technician has the following six drives available:
Which of the following drive selections should the technician utilize to best accomplish this goal?
- A. 1, 2, 3, 5, and 6
- B. 1, 2, 4, 5, and 6
- C. 1,2, 4, and 6
- D. 1, 2, 3, 4, and 6
Answer: B
Explanation:
RAID 5 configuration: Using five of the available drives in a RAID 5 configuration meets the requirements for:
Storage capacity: Four 600GB drives (2, 5, and 6) provide a total usable capacity of 2.4TB (4 *
600 * 0.8), exceeding the minimum requirement of 2TB. RAID 5 introduces parity data for fault tolerance, sacrificing some usable space (one drive's worth).
Performance: The combination of multiple drives in a RAID 5 array improves read performance compared to a single drive setup.
Fault tolerance: Even with a single drive failure (any of the five drives used in the RAID 5), the remaining drives can reconstruct the lost data, allowing the server to continue operating.
NEW QUESTION # 212

(Select two).
- A. 0
- B. 1
- C. 2
- D. 3
- E. 4
- F. 5
- G. 6
Answer: B,E
Explanation:
Explanation
Port 443 is used for HTTPS, which is a secure version of HTTP that encrypts the data between the web server and the client. Port 3389 is used for RDP, which is a protocol that allows remote desktop connections to a server. These ports should be allowed for a secure web server that can be administered via RDP.

NEW QUESTION # 213
Which of the following should a server administrator use when writing a script with a function that needs to be run ten times?
- A. Loop
- B. Variable
- C. Comparator
- D. Conditional
Answer: A
Explanation:
A loop is a programming construct used to repeat a block of code multiple times. In this case, if a function needs to run ten times, a loop (such as a for loop or while loop) would be the appropriate choice.
* Loop (Answer A): This allows the function to be executed repeatedly without writing redundant code.
* Variable (Option B): A variable is used to store data, but it doesn't handle repetition.
* Comparator (Option C): Comparators are used to compare values, not for repeating code.
* Conditional (Option D): Conditionals (if, else) are used for decision-making, not repeating actions multiple times.
