NEW QUESTION # 144
Which of the following can be BEST described as the amount of time a company can afford to be down during recovery from an outage?
- A. MTTR
- B. SLA
- C. RTO
- D. MTBF
Answer: C
Explanation:
Explanation
The term that best describes the amount of time a company can afford to be down during recovery from an outage is RTO. RTO (Recovery Time Objective) is a metric that defines the maximum acceptable downtime for an application, system, or process after a disaster or disruption. RTO helps determine the level of urgency and resources required for restoring normal business operations. RTO is usually measured in minutes, hours, or days, depending on the criticality and impact of the service.
NEW QUESTION # 145
Which of the following open ports should be closed to secure the server properly? (Choose two.)
- A. 0
- B. 1
- C. 2
- D. 3
- E. 4
- F. 5
Answer: E,F
Explanation:
The administrator should close ports 21 and 23 to secure the server properly. Port 21 is used for FTP (File Transfer Protocol), which is an unsecure protocol that allows file transfer between a client and a server over a network connection. FTP does not encrypt the data or the credentials that are transmitted, making them vulnerable to interception or modification by attackers. Port 23 is used for Telnet, which is an unsecure protocol that allows remote login and command execution over a network connection using a CLI. Telnet does not encrypt the data or the credentials that are transmitted, making them vulnerable to interception or modification by attackers.
NEW QUESTION # 146
Which of the following commands should a systems administrator use to create a batch script to map multiple shares'?
- A. netstst
- B. tracert
- C. nbtstat
- D. netuse
Answer: D
Explanation:
net use [devicename | *] [\\computername\sharename[\u0003volume] [password | *]] [/user:[domainname\]username] [/user:[dotted domain name\]username] [/user:[[username@dotted domain name] [/savecred] [/smartcard] [{/delete | /persistent:{yes | no}}] where:
devicename = the drive letter or printer port to assign to the shared resource computername = the name of the computer that provides access to the shared resource sharename = the name of the shared resource password = the password needed to access the shared resource /user = specifies a different username to make the connection /savecred = stores the provided credentials for future use /smartcard = uses a smart card for authentication /delete = cancels a network connection and removes the connection from the list of persistent connections /persistent = controls whether the connection is restored at logon To create a batch script to map multiple shares, you can use the net use command with different drive letters and share names, for example:
net use W: \\computer1\share1 net use X: \\computer2\share2 net use Y: \\computer3\share3 You can also add other options, such as passwords, usernames, or persistence, as needed. To save the batch script, you can use Notepad or any text editor and save the file with a .bat extension12.

NEW QUESTION # 147
A company needs a media server set up that provides the highest availability with a minimum requirement of at least 10TB. The company purchased five HDDs, each with a 4TB capacity. Which of the options would provide the highest fault tolerance and meet the requirements?
- A. RAID 5
- B. RAID 6
- C. RAID 0
- D. RAID 10
Answer: B
Explanation:
RAID 6 is a RAID level that uses disk striping with two parity blocks distributed across all member disks. It can tolerate the failure of up to two disks without losing any dat a. RAID 6 can provide a minimum of 10TB of usable storage space with five 4TB disks, as the formula for calculating the RAID 6 capacity is (n-2) x Smin, where n is the number of disks and Smin is the smallest disk size. In this case, the RAID 6 capacity is (5-2) x 4TB = 12TB.

NEW QUESTION # 148
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 5
- B. RAID 1
- C. RAID 0
- D. RAID 6
Answer: C
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 # 149
A server administrator wants to ensure a storage array can survive the failure of two drives without the loss of data. Which of the following RAID levels should the administrator choose?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: A
Explanation:
Explanation
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. References:

NEW QUESTION # 150
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. There are mismatched RAM modules.
- C. The CPU has failed.
- D. RAID 5 requires four drives
- E. There are multiple failed hard drives.
Answer: E
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-

NEW QUESTION # 151
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, and 6
- C. 1, 2, 4, 5, and 6
- D. 1, 2, 3, 4, and 6
Answer: C
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 # 153
Which of the following BEST describes a guarantee of the amount of time it will take to restore a downed service?
- A. MTTR
- B. SLA
- C. RTO
- D. MTBF
Answer: C
Explanation:
RTO stands for Recovery Time Objective and it is a metric that defines the maximum acceptable amount of time that a system or service can be unavailable after a disaster or disruption. RTO is part of the business continuity planning and disaster recovery planning processes. RTO ensures a guarantee of the amount of time it will take to restore a downed service by setting a target or goal for recovery. RTO can vary depending on the criticality and priority of the service.

An administrator needs to disable root login over SSH. Which of the following tiles should be edited to complete this task?
- A. /root/.ssh/ssh_config
- B. /etc.ssh/sshd_config
- C. /root.ssh/sshd/config
- D. /etc.sshs_shd_config
Answer: B
Explanation:
To disable root login over SSH, the server administrator needs to edit the SSH configuration file located at
/etc/ssh/sshd_config. This file contains various settings for the SSH daemon that runs on the server and accepts incoming SSH connections. The administrator needs to find the line that says PermitRootLogin and change it to no or comment it out with a # symbol. Then, the administrator needs to restart the SSH service for the changes to take effect. References:

NEW QUESTION # 159
Users report that the FinanceApp software is not running, and they need immediate access. Issues with the FinanceApp software occur every week after the IT team completes server system updates. The users, however, do not want to contact the help desk every time the issue occurs. The users also report the new MarketApp software is not usable when it crashes, which can cause significant downtime. The technician who restarted the MarketApp software noticed it is running under a test account, which is a likely cause of the crashes.
INSTRUCTIONS
Using the Services menu provided, modify the appropriate application services to remedy the stated issues.
Answer:
Explanation:
FinanceApp software is running as a service named "FinanceApp Service". The service description says "Provides financial data and calculations for the FinanceApp software". The service status is "Stopped", which means that the service is not running and the software is not functional. The service startup type is "Manual", which means that the service needs to be started manually by the user or the administrator. The service log on as is "Local System", which means that the service runs under a predefined local account that has extensive privileges on the local computer.
To fix the issue with the FinanceApp software, you need to do two things:
First, you need to start the service, so that the software can run. To do this, you can right-click on the service name and select "Start" from the menu. Alternatively, you can select the service name and click on the "Start" button on the toolbar. You should see a message saying that the service has started successfully.
Second, you need to change the service startup type, so that the service can start automatically every time the server boots up. This way, you don't have to contact the help desk every time the issue occurs. To do this, you can right-click on the service name and select "Properties" from the menu. Alternatively, you can select the service name and click on the "Properties" button on the toolbar. You should see a window with several tabs and options. On the "General" tab, under "Startup type", you can select "Automatic" from the drop-down list. Then, click on "OK" to save your changes.
By doing these two steps, you should be able to use the FinanceApp software without any problems.
The MarketApp software is running as a service named "MarketApp Service". The service description says "Provides market data and analysis for the MarketApp software". The service status is "Running", which means that the service is running and the software is functional. However, as you reported, the software may crash sometimes, which can cause significant downtime. The service startup type is "Automatic", which means that the service starts automatically every time the server boots up. The service log on as is "TestAccount", which is a test account that was probably used for development or testing purposes.
To fix the issue with the MarketApp software, you need to do one thing:
You need to change the service log on as, so that the service runs under a proper account that has sufficient permissions and security settings for production use. To do this, you can right-click on the service name and select "Properties" from the menu. Alternatively, you can select the service name and click on the "Properties" button on the toolbar. You should see a window with several tabs and options. On the "Log On" tab, under "Log on as", you can select either "Local System account" or "This account". If you choose "Local System account", then the service will run under a predefined local account that has extensive privileges on the local computer. If you choose "This account", then you will need to enter a valid username and password for an account that has appropriate permissions and security settings for running the service. You may need to consult with your IT team or your software vendor to determine which option is best for your situation. Then, click on "OK" to save your changes.
