NEW QUESTION # 167
Which of the following backup types only records changes to the data blocks on a virtual machine?
- A. Synthetic full
- B. Differential
- C. Incremental
- D. Snapshot
Answer: D
Explanation:
Explanation
The backup type that only records changes to the data blocks on a virtual machine is snapshot. A snapshot is a point-in-time copy of a virtual machine (VM) that captures the state and data of the VM at a specific moment.
A snapshot can be created instantly and with minimal overhead, as it only stores the changes made to the VM after the snapshot was taken. A snapshot can be used to restore the VM to its previous state in case of data loss or corruption.

NEW QUESTION # 171
Which of me following should be placed at the top of a Bash script to ensure it can be executed?
- A. bash
- B. #!
- C. !execute
- D. @eacho off
Answer: B
Explanation:
Explanation
#! 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.

NEW QUESTION # 172
A company wants to find an affordable way to simulate a fail over of a critical application. The company does not currently have a solution for it. The application consists of 15 servers, and the company would like to simulate on production configurations and IP address schemes. Which of the following would be the most cost-effective solution?
- A. Perform a tabletop fail over of the application.
- B. Build a cold site and perform a fail over of the application.
- C. Build a warm site and perform a fail over of the application.
- D. Build a cloud laaS and perform a fail over of the application.
- E. Build a hot site and perform a fail over of the application.
Answer: D
Explanation:
Explanation
Cloud IaaS (Infrastructure as a Service) is a service model that allows users to rent virtualized computing resources over the internet, such as servers, storage, network, and software. Cloud IaaS can provide several benefits for disaster recovery and failover scenarios, such as:
Lower cost: Cloud IaaS can reduce the capital and operational expenses of building and maintaining a physical disaster recovery site, as users only pay for the resources they use on demand12.
Scalability: Cloud IaaS can offer flexible and elastic scalability of resources, as users can easily provision or deprovision resources according to their needs and workload12.
Availability: Cloud IaaS can ensure high availability and reliability of the application, as users can leverage the cloud provider's redundant and geographically distributed infrastructure12.
Simplicity: Cloud IaaS can simplify the failover process, as users can use the cloud provider's tools and services to automate and orchestrate the failover operations12.
Therefore, building a cloud IaaS and performing a failover of the application would be the most cost-effective solution for the company, as it would allow them to simulate a failover of a critical application on production configurations and IP address schemes without investing in a physical disaster recovery site.
NEW QUESTION # 173
A server administrator is swapping out the GPU card inside a server. Which of the following actions should the administrator take FIRST?
- A. Disconnect the power from the rack.
- B. Shut down the server.
- C. Ensure the GPU meets HCL guidelines.
- D. Inspect the GPU that is being installed.
Answer: B
Explanation:
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:

NEW QUESTION # 174
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. Replace all the drives in both degraded arrays.
- B. Shut down the server and replace the drives.
- C. Replace one drive, wait for a rebuild, and replace the next drive.
- D. Replace both failed drives at the same time.
Answer: D
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. Reference: https://en.wikipedia.org/wiki/Standard_RAID_levels#RAID_1
NEW QUESTION # 175
An organization purchased six new 4TB drives for a server. An administrator is tasked with creating an efficient RAID given the minimum disk space requirement of 19TBs. Which of the following should the administrator choose to get the most efficient use of space?
- A. RAID 5
- B. RAID 1
- C. RAID 10
- D. RAID 6
Answer: A
Explanation:
Explanation
RAID 5 is a RAID level that uses disk striping with parity. It requires a minimum of three disks and can handle one disk failure. RAID 5 distributes the parity information across all the disks in the array, which improves the read performance and reduces the write penalty. The capacity of a RAID 5 array is (N-1) times the size of the smallest disk, where N is the number of disks in the array. Therefore, for six 4TB disks, the capacity of a RAID 5 array would be (6-1) x 4TB = 20TB, which meets the minimum disk space requirement of 19TB. RAID 5 also has the least amount of disk space lost to RAID overhead among the options, as it only uses one disk's worth of space for parity
NEW QUESTION # 176
A company is building a new datacenter next to a busy parking lot. Which of the following is the BEST strategy to ensure wayward vehicle traffic does not interfere with datacenter operations?
- A. Install bollards
- B. Install security cameras
- C. Utilize security guards
- D. Install a mantrap
Answer: A
Explanation:
The best strategy to ensure wayward vehicle traffic does not interfere with datacenter operations is to install bollards. Bollards are sturdy posts that are installed around a perimeter to prevent vehicles from entering or crashing into a protected area. Bollards can provide physical security and deterrence for datacenters that are located near busy roads or parking lots. Bollards can also prevent accidental damage or injury caused by vehicles that lose control or have faulty brakes.

NEW QUESTION # 179
Following a recent power outage, a server in the datacenter has been constantly going offline and losing its configuration. Users have been experiencing access issues while using the application on the server. The server technician notices the data and time are incorrect when the server is online. All other servers are working. Which of the following would MOST likely cause this issue? (Choose two.)
- A. The server has a malfunctioning LED panel
- B. The time synchronization service is disabled on the servers
- C. The server requires OS updates
- D. The servers do not have NTP configured
- E. The server has a faulty power supply
- F. The server has a CMOS battery failure
Answer: B,F
Explanation:
The server has a CMOS battery failure and the time synchronization service is disabled on the servers. The CMOS battery is a small battery on the motherboard that powers the BIOS settings and keeps track of the date and time when the server is powered off. If the CMOS battery fails, the server will lose its configuration and display an incorrect date and time when it is powered on. This can cause access issues for users and applications that rely on accurate time stamps. The time synchronization service is a service that synchronizes the system clock with a reliable external time source, such as a network time protocol (NTP) server. If the time synchronization service is disabled on the servers, they will not be able to update their clocks automatically and may drift out of sync with each other and with the network. This can also cause access issues for users and applications that require consistent and accurate time across the network.
NEW QUESTION # 180
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 core
- B. Per site
- C. Per instance
- D. Per concurrent user
Answer: D
Explanation:
Explanation
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. References:

Which of the following would BEST help answer the server performance question9
- A. A server baseline
- B. Server performance thresholds
- C. An application service-level agreement
- D. A hardware compatibility list
Answer: A
Explanation:
Explanation
A server baseline is a set of metrics that represents the normal performance and behavior of a server under a specific workload and configuration. A server baseline can help answer the server performance question by comparing the current performance with the previous performance before the upgrade. This can help identify any changes or issues that may have affected the server performance. References:

NEW QUESTION # 184
A technician is connecting a server's secondary NIC to a separate network. The technician connects the cable to the switch but then does not see any link lights on the NIC. The technician confirms there is nothing wrong on the network or with the physical connection. Which of the following should the technician perform NEXT?
- A. Restart the server
- B. Enable the port on the server
- C. Check the DHCP configuration
- D. Configure the network on the server
Answer: B
Explanation:
The next thing that the technician should perform is to enable the port on the server. A port is a logical endpoint that identifies a specific service or application on a network device. A port can be enabled or disabled depending on whether the service or application is running or not. If a port is disabled on a server, it means that the server cannot send or receive any network traffic on that port, which can prevent communication with other devices or services that use that port. In this case, if port 389 is disabled on the server, it means that the server cannot use LDAP to access or modify directory services over a network. To resolve this issue, the technician should enable port 389 on the server using commands such as netsh or iptables.
NEW QUESTION # 185
Which of the following if properly configured would prevent a user from installing an OS on a server? (Select TWO).
- A. Group Policy Object
- B. SELInux
- C. Bootloader password
- D. Root password
- E. Administrator password
- F. BIOS/UEFI password
Answer: C,F
Explanation:
Requiring a boot password upon execution of the boot loader will prevent an unauthorized user from entering boot parameters or changing the boot partition. This prevents users from weakening security (e.g. turning off SELinux at boot time).
What is a UEFI password?
A UEFI, or BIOS, password is a password that must be entered when the machine is powered on or rebooted in order to continue. Without the password the machine cannot be booted at all - even from external media - and no configuration changes to the UEFI or BIOS settings can be made.

NEW QUESTION # 187
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. RAID 5 requires four drives
- B. There are multiple failed hard drives.
- C. There are mismatched RAM modules.
- D. The page file is too small.
- E. The CPU has failed.
Answer: B
Explanation:
Explanation
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: https://www.technewstoday.com/what-is-a-raid-5/
NEW QUESTION # 188
Which of the following are measures that should be taken when a data breach occurs? (Select TWO).
- A. Disable unnecessary ports.
- B. Disclose the incident.
- C. Identify the exploited vulnerability.
- D. Restore the data from backup.
- E. Move the data to a different location.
- F. Run an antivirus scan.
Answer: B,C
Explanation:
Explanation
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. References:
