NEW QUESTION # 124
A server administrator added a new drive to a server. However, the drive is not showing up as available. Which of the following does the administrator need to do to make the drive available?
- A. Set the compression.
- B. Create a new disk quota.
- C. Configure the drive as dynamic.
- D. Partition the drive.
Answer: D
Explanation:
To make a new drive available on a server, the administrator needs to partition the drive first. Partitioning is a process that divides the drive into one or more logical sections that can be formatted and assigned drive letters or mount points. Partitioning can be done using tools such as Disk Management on Windows or fdisk on Linux. Creating a new disk quota would not help, as disk quotas are used to limit the amount of disk space that users or groups can use on a partition. Configuring the drive as dynamic would not help either, as dynamic disks are used to create volumes that span multiple disks or use RAID features. Setting the compression would not help, as compression is used to reduce the size of files on a partition.

NEW QUESTION # 129
Which of the following is the MOST appropriate scripting language to use for a logon script for a Linux box?
- A. PowerShell
- B. VBS
- C. Batch
- D. Shell
- E. Java
Answer: D
Explanation:
Scripts are written using a shell language. The shell is the server's command-line environment.
The default shell for Linux is bash. Windows has two shells: cmd.exe and PowerShell, although Microsoft emphasizes PowerShell. As a general rule, a script written for one shell, such as PowerShell, will not be understood by another shell, such as bash. The system must have the appropriate shell installed to process the script.
Bash script -- a script written in bash language that contains commands, variables, constructs, and other components. Bash scripts are almost always written for Linux systems.
VBS script -- a script written in the VBScript language. Microsoft has deprecated VBScript, but there have been many VBScript scripts written over the years. VBScript scripts are almost always written for Windows systems.
NEW QUESTION # 130
An administrator needs to increase the size of an existing RAID 6 array that is running out of available space. Which of the following is the best way the administrator can perform this task?
- A. Replace the array drives one at a time and then expand the array.
- B. Replace all the array drives at once and then expand the array.
- C. Expand the array by changing the RAID level to 10.
- D. Expand the array by changing the RAID level to 6.
Answer: A
Explanation:
RAID 6 is a type of RAID that uses block-level striping with two parity blocks distributed across all member disks. It allows for two disk failures within the RAID set before any data is lost1. A minimum of four disks is required to create RAID 61. To increase the size of an existing RAID 6 array, the administrator can replace the array drives one at a time with larger drives and then expand the array. This way, the data and parity are rebuilt on each new drive and the array remains operational during the process2.

NEW QUESTION # 132
A large number of connections to port 80 is discovered while reviewing the log files on a server. The server is not functioning as a web server. Which of the following represent the BEST immediate actions to prevent unauthorized server access? (Choose two.)
- A. Stop all unneeded services and block the ports on the firewall
- B. Install a NIDS on the server to prevent network intrusions
- C. Run a checksum tool against all the files on the server
- D. Enable port forwarding on port 80
- E. Initialize a port scan on the server to identify open ports
- F. Audit all group privileges and permissions
Answer: A,B
Explanation:
The best immediate actions to prevent unauthorized server access are to stop all unneeded services and block the ports on the firewall. Stopping unneeded services reduces the attack surface of the server by eliminating potential entry points for attackers. For example, if the server is not functioning as a web server, there is no need to run a web service on port 80. Blocking ports on the firewall prevents unauthorized network traffic from reaching the server. For example, if port 80 is not needed for any legitimate purpose, it can be blocked on the firewall to deny any connection attempts on that port.
NEW QUESTION # 133

- A. Make the changes to the system.
- B. Inform the impacted users.
- C. Identify changes to the server.
- D. Determine the probable causes.
Answer: D
Explanation:
The step that the server administrator should perform before resolving the issue is to determine the probable causes. This step is part of the troubleshooting process that follows a logical and systematic approach to identify and solve problems with servers and applications. The troubleshooting process consists of several steps, such as:
Identify the problem: Gather information from various sources, such as users, logs, or alerts, to understand the symptoms and scope of the problem.
Establish a theory of probable cause: Analyze the information and formulate one or more possible causes of the problem based on evidence or experience.
Test the theory to determine cause: Perform tests or experiments to verify or eliminate each possible cause until the root cause is found.
Establish a plan of action to resolve the problem and implement the solution: Design and execute a plan to fix the problem using appropriate tools and techniques.
Verify full system functionality and implement preventive measures: Confirm that the problem is resolved and that no other issues arise as a result of the solution. Implement preventive measures to avoid recurrence of the problem or improve performance.
Document findings, actions, and outcomes: Record the details of the problem, its cause, its solution, and its outcome for future reference or knowledge sharing.

NEW QUESTION # 134
In which of the following media rotation schemes are daily, weekly, and monthly backup media utilized in a first-in, first-out method?
- A. Waterfall
- B. Synthetic full
- C. Grandfather-father-son
- D. Tower of Hanoi
Answer: C
Explanation:
Explanation
Grandfather-father-son (GFS) is a common backup rotation scheme that uses daily, weekly, and monthly backup media in a first-in, first-out (FIFO) method. The daily backups are rotated on a 3-months basis using a FIFO system as above. The weekly backups are similarly rotated on a bi-yearly basis, and the monthly backups are rotated on an annual basis. The oldest backup media in each cycle are overwritten by the newest ones. This scheme provides multiple versions of backup data at different intervals, allowing for flexible restoration options. Waterfall is another name for GFS. Synthetic full is a backup method that combines an initial full backup with subsequent incremental backups to create a new full backup without transferring all data again. Tower of Hanoi is another backup rotation scheme that uses an algorithm based on moving disks between three pegs. References:

Which of the following concepts is in use when dual power supplies are connected to different power sources?
- A. Component redundancy
- B. Fault tolerance
- C. Active-passive
- D. Heartbeat
- E. Link aggregation
Answer: B
Explanation:
The concept in use when dual power supplies are connected to different power sources is fault tolerance. Fault tolerance is the ability of a system to continue operating without interruption or loss of data in the event of a failure of one or more components. By connecting dual power supplies to different power sources, the system can switch to the alternative power supply or source if one fails, ensuring continuous availability and reliability.

NEW QUESTION # 137
A server administrator was asked to build a storage array with the highest possible capacity. Which of the following RAID levels should the administrator choose?
- A. RAID 0
- B. RAID 1
- C. RAID 6
- D. RAID 5
Answer: A
Explanation:
Explanation
The RAID level that provides the highest possible capacity for a storage array is RAID 0. RAID 0 is a type of RAID level that provides performance enhancement by using striping. Striping means dividing data into blocks and distributing them across multiple disks to increase speed and capacity. RAID 0 does not provide any fault tolerance or redundancy, as it does not use any parity or mirroring techniques. RAID 0 uses all of the available disk space for data storage, without losing any space for overhead. Therefore, RAID 0 provides the highest possible capacity for a storage array, but also has the highest risk of data loss.
NEW QUESTION # 138
Users ate experiencing issues when trying to access resources on multiple servers. The servers are virtual and run on an ESX server. A systems administrator is investigating but is unable to connect to any of the virtual servers. When the administrator connects to the host, a purple screen with while letters appears. Which of the following troubleshooting steps should the administrator perform FIRST?
- A. Review the log files.
- B. Reinstall the ESX server.
- C. Check the power supplies
- D. Reseat the processors.
Answer: A
Explanation:
Explanation
A purple screen with white letters on an ESX server indicates a kernel panic, which is a fatal error that causes the system to crash and stop functioning . The first troubleshooting step that an administrator should perform is to review the log files, which may contain information about the cause of the error, such as hardware failures, software bugs, or configuration issues . Checking the power supplies (A) may not be relevant, as the system is still displaying a screen. Reinstalling the ESX server or reseating the processors (D) are drastic measures that may result in data loss or further damage, and should only be attempted after ruling out other possible causes.

However, it also requires more synchronization and coordination between the nodes to avoid conflicts or errors. Verified References: [Active-active], [Redundant system]
NEW QUESTION # 141
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. Bare metal
- B. Core
- C. Full
- D. GUI
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 # 142
Users in an office lost access to a file server following a short power outage. The server administrator noticed the server was powered off. Which of the following should the administrator do to prevent this situation in the future?
- A. Connect the server to a redundant network
- B. Connect the server to a UPS
- C. Use cable management
- D. Connect the server to a KVM
Answer: B
Explanation:
