Question 312:
A technician is laying out a filesystem on a new Linux server. Which of the following tools would work BEST to allow the technician to increase a partition's size in the future without reformatting it?
A. LVM
B. DiskPart
C. fdisk
D. Format
Correct Answer: A
LVM (Logical Volume Manager) is a tool that allows the technician to increase a partition's size in the future without reformatting it on a Linux server. LVM creates logical volumes that can span across multiple physical disks or partitions and
can be resized dynamically without losing data. LVM also provides other features such as snapshots, encryption, and RAID. DiskPart, fdisk, and Format are tools that can be used to partition and format disks, but they do not allow increasing
A server administrator is deploying a new server that has two hard drives on which to install the OS. Which of the following RAID configurations should be used to provide redundancy for the OS?
A. RAID 0
B. RAID 1
C. RAID 5
D. RAID 6
Correct Answer: B
RAID 1 (mirroring) is a RAID configuration that should be used to provide redundancy for the OS on a server that has two hard drives on which to install the OS. RAID 1 (mirroring) is a configuration that duplicates data across two or more drives. It provides fault tolerance and improves read performance, but reduces storage capacity by half. If one drive fails in RAID 1, the other drive can continue to operate without data loss or system downtime. RAID 0 (striping) is a configuration that splits data across two or more drives without parity or redundancy. It improves performance but offers no fault tolerance. If one drive fails in RAID 0, all data is lost and the system cannot boot. RAID 5 (striping with parity) is a configuration that stripes data across three or more drives with parity information. It provides fault tolerance and improves performance, but reduces storage capacity by one drive's worth of space. RAID 5 can tolerate one drive failure without data loss, but not two or more. RAID 6 (striping with double parity) is a configuration that stripes data across four or more drives with double parity information. It provides fault tolerance and improves performance, but reduces storage capacity by two drives' worth of space. RAID 6 can tolerate two drive failures without data loss, but not three or more.

Question 314:
A backup application is copying only changed files each line it runs. During a restore, however, only a single file is used. Which of the following backup methods does this describe?
A. Open file
B. Synthetic full
C. Full Incremental
D. Full differential
Correct Answer: B
A synthetic full backup is a backup method that describes copying only changed files each time it runs and using only a single file during a restore. A synthetic full backup is a backup approach that involves creating a new full backup by using
the previous full backup and related incremental backups. This means that a backup solution does not have to transfer the full amount of data from the source machine and can synthetize the latest incremental backups with the last full
backup to create a new full backup. This reduces the backup window and network bandwidth consumption. During a restore, only the latest synthetic full backup file is needed to recover the data. Open file backup is a backup method that
allows backing up files that are in use or locked by applications. Full incremental backup is a backup method that involves performing a full backup first and then backing up only the changed files since the last backup. Full differential backup
is a backup method that involves performing a full backup first and then backing up only the changed files since the last full backup.
An administrator is investigating a physical server mat will not Boot into the OS. The server has three hard drives configured in a RAID 5 array. The server passes POST, out the OS does not load. The administrator verities the CPU and RAM
are Doth seated correctly and checks the dual power supplies. The administrator then verifies all the BIOS settings are correct and connects a bootable USB drive in the server, and the OS loads correctly.
Which of the following is causing the issue?
A. The page file is too small.
B. The CPU has failed.
C. There are multiple failed hard drives.
D. There are mismatched RAM modules.
E. RAID 5 requires four drives
Correct Answer: C
If a server has three hard drives configured in a RAID 5 array, it means that the data is striped across all three drives with parity information. RAID 5 can tolerate one drive failure without losing data, but not two or more. If there are multiple
failed hard drives, the RAID 5 array will become corrupted and the OS will not load. The other options are not likely to cause the issue, as the server passes POST, the CPU and RAM are seated correctly, the BIOS settings are correct, and
the OS loads from a bootable USB drive. RAID 5 does not require four drives, it can work with three or more. References:

Question 316:
Which of the following are measures that should be taken when a data breach occurs? (Select TWO).
A. Restore the data from backup.
B. Disclose the incident.
C. Disable unnecessary ports.
D. Run an antivirus scan.
E. Identify the exploited vulnerability.
F. Move the data to a different location.
Correct Answer: BE
These are two measures that should be taken when a data breach occurs. A data breach is an unauthorized or illegal access to confidential or sensitive data by an internal or external actor. A data breach can result in financial losses, reputational damage, legal liabilities, and regulatory penalties for the affected organization. Disclosing the incident is a measure that involves informing the relevant stakeholders, such as customers, employees, partners, regulators, and law enforcement, about the nature, scope, and impact of the data breach. Disclosing the incident can help to mitigate the negative consequences of the data breach, comply with legal obligations, and restore trust and confidence. Identifying the exploited vulnerability is a measure that involves investigating and analyzing the root cause and source of the data breach. Identifying the exploited vulnerability can help to prevent further data loss, remediate the security gaps, and improve the security posture of the organization. Restoring the data from backup is a measure that involves recovering the lost or corrupted data from a secondary storage device or location. However, this does not address the underlying issue of how the data breach occurred or prevent future breaches. Disabling unnecessary ports is a measure that involves closing or blocking network communication endpoints that are not required for legitimate purposes. However, this does not address how the data breach occurred or what vulnerability was exploited. Running an antivirus scan is a measure that involves detecting and removing malicious software from a system or network. However, this does not address how the data breach occurred or what vulnerability was exploited. Moving the data to a different location is a measure that involves transferring the data to another storage device or location that may be more secure or less accessible. However, this does
not address how the data breach occurred or what vulnerability was exploited.
A technician is attempting to reboot a remote physical Linux server. However, attempts to command a shutdown -----now result in the loss of the SSH connection. The server still responds to pings. Which of the following should the technician use to command a remote shutdown?
A. Virtual serial console
B. A KVM
C. An IDRAC
D. A crash cart
Correct Answer: C
An IDRAC (Integrated Dell Remote Access Controller) is a tool that can be used to command a remote shutdown of a physical Linux server. An IDRAC is a hardware device that provides out-of-band management for Dell servers. It allows the technician to access the server's console, power cycle, reboot, or shut down the server remotely using a web interface or a command-line interface. An IDRAC does not depend on the operating system or network connectivity of the server. A virtual serial console is a tool that can be used to access a remote virtual machine's console using a serial port connection. A KVM (Keyboard, Video, Mouse) switch is a device that allows the technician to switch between different computer sources using the same keyboard, monitor, and mouse. A crash cart is a mobile unit that contains a keyboard, monitor, mouse, and other tools that can be connected to a physical server for troubleshooting purposes.

Question 318:
Which of me following should be placed at the top of a Bash script to ensure it can be executed?
A. bash
B. !execute
C. #!
D. @eacho off
Correct Answer: C
#! is the symbol that should be placed at the top of a Bash script to ensure it can be executed. #! is also known as shebang or hashbang. It is a special notation that tells the operating system which interpreter to use to run the script. The
shebang is followed by the path to the interpreter, such as /bin/bash for Bash, /bin/python for Python, or /bin/perl for Perl. For example, a Bash script that prints "Hello World" would start with:
#!/bin/bash echo "Hello World"
The shebang must be the first line of the script and must not have any spaces between the # and ! symbols. bash is not a valid shebang by itself, as it does not specify the path to the interpreter. !execute is not a valid shebang at all, as it does
not start with #. @echo off is a command that disables the echoing of commands in a batch file on Windows, but it has nothing to do with Bash scripts on Linux.
A company wants to deploy software to all users, Out very few of men will be using the software at any one point in time. Which of the following licensing models would be BEST lot the company?
A. Per site
B. Per concurrent user
C. Per core
D. Per instance
Correct Answer: B
Per concurrent user licensing is a model that allows a fixed number of users to access the software at any one point in time. This model is best for the company that wants to deploy software to all users, but very few of them will be using the software at any one point in time. This way, the company can save money by paying only for the number of simultaneous users, rather than for every user who has access to the software. Per site licensing is a model that allows unlimited users within a specific location to use the software. Per core licensing is a model that charges based on the number of processor cores on the server where the software is installed. Per instance licensing is a model that charges based on the number of copies of the software running on different servers or virtual machines.

Question 320:
A datacenter in a remote location lost power. The power has since been restored, but one ol the servers has not come back online. After some investigation, the server is found to still be powered off. Which of the following is the BEST method to power on the server remotely?
A. Crash cart
B. Out-of-band console
C. IP KVM
D. RDP
Correct Answer: B
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.
