• Question 421:

  A server administrator noticesthe/var/log/audit/audit.logfileon a Linux server is rotating loo frequently. The administrator would like to decrease the number of times the leg rotates without losing any of the information in the logs. Which of the following should the administrator configure?

  A. increase theaudit. log file size in the appropriate confutation file.

  B. Decrease the duration of the log rotate cycle tor theaudit. log file.

  C. Remove the tog rotate directive from the audit .log We configuration.

  D. Move the audit. leg files to a remote syslog server.

  Correct Answer: A

  The audit.log file is a file that records security-related events on a Linux server, such as user login, file access, and system commands. The logrotate utility is a tool that rotates, compresses, and deletes old log files based on certain criteria, such as size, time, or frequency. To decrease the number of times the log rotates without losing any information, the administrator should increase the audit.log file size in the appropriate configuration file, such as /etc/logrotate.conf or /etc/ logrotate.d/auditd.

• Question 422:

  Several new components have been added to a mission-critical server, and corporate policy states all new components must meet server hardening requirements. Which of the following should be applied?

  A. Definition updates

  B. Driver updates

  C. OS security updates

  D. Application updates

  Correct Answer: B

  Driver updates should be applied to the new components that have been added to a mission-critical server, as part of the server hardening requirements. Drivers are software programs that enable the communication and functionality of hardware devices, such as network cards, storage controllers, or graphics cards. Updating drivers can improve the performance, compatibility, and stability of the new components with the server operating system and applications.

• Question 423:

  Which of the following symbols is used to write a text description per line within a PowerShell script?

  A. %

  B. @

  C. and

  D. #

  Correct Answer: D

  The # symbol is used to write a text description per line within a PowerShell script. A text description is also known as a comment, which is a line of code that is ignored by the PowerShell interpreter and serves as documentation or

  explanation for human readers. The # symbol indicates that everything following it on the same line is a comment and not part of the script commands or expressions. For example:

  This is a comment in PowerShellWrite-Host "Hello World" # This command prints Hello World to the console

• Question 424:

  A technician set up a new multifunction printer. After adding the printer to the print server, the technician configured the printer on each user's machine. Several days later, users reported that they were no longer able to print, but scanning to email worked. Which of the following is most likely causing this issue?

  A. The gateway is no longer being reached.

  B. The network firewall was enabled.

  C. The printer's network interface failed.

  D. The printer had DHCP enabled.

  Correct Answer: D

  The most likely cause of this issue is that the printer had DHCP enabled, which changed its IP address after adding it to the print server and configuring it on each user's machine. DHCP (Dynamic Host Configuration Protocol) is a network protocol that assigns IP addresses and other network configuration parameters to devices automatically, without manual intervention. DHCP can simplify network management and avoid IP conflicts, but it can also cause problems if the devices are not configured to use static or reserved IP addresses. If the printer had DHCP enabled, it might have received a different IP address from the DHCP server after rebooting or reconnecting to the network, which would make it unreachable by the print server and the users' machines that were configured with the previous IP address. Scanning to email would still work, as it does not depend on the print server or the users' machines, but on the printer's SMTP settings and internet connection.

• Question 425:

  A server administrator is creating a script that will move files only if they were created before a date input by the user. Which of the following constructs will allow the script to apply this test until all available files are assessed?

  A. Variable

  B. Loop

  C. Comparator

  D. Conditional

  Correct Answer: B

  A loop is a script construct that allows the script to repeat a block of code until a certain condition is met or for a specified number of times. A loop can be used to apply a test to each file in a directory and move the files that meet the criteria.

  For example, in a bash script, a loop can be written as:

  #!/bin/bash

  # Ask the user for the date

  echo"Enter the date (YYYY-MM-DD):"

  readdate

  # Loop through all the files in the current directory forfilein*

  do

  # Check if the file was created before the date

  if[[ $(date-r"$file"+%F) <$date]]

  then

  # Move the file to another location

  mv"$file"/path/to/destination

  fi

  done

  Copy

  A variable is a script construct that allows the script to store and manipulate data. A variable can be used to store the date input by the user, but it cannot apply a test to each file1 A comparator is a script construct that allows the script to

  compare two values and determine their relationship. A comparator can be used to check if a file was created before the date, but it cannot repeat the test for all files1 A conditional is a script construct that allows the script to execute different

  blocks of code based on certain conditions. A conditional can be used to decide whether to move a file or not, but it cannot iterate over all files1

• Question 426:

  An analyst is planning a new point-to-point Ethernet connection between a university campus and a newly acquired space downtown that is about 5mi (8km) away. The analyst would like the fastest possible connection speed. Which of the following would best meet the analyst's needs?

  A. 1000BASE-LX 1Gb single-mode plenum fiber connection

  B. 10GBASE-T 10Gb copper plenum Ethernet connection

  C. 1000BASE-T 1Gb copper non-plenum Ethernet connection

  D. 10GBASE-SR 10Gb multimode plenum fiber connection

  Correct Answer: A

  A 1000BASE-LX 1Gb single-mode plenum fiber connection would best meet the analyst's needs for a new point-to-point Ethernet connection between a university campus and a newly acquired space downtown that is about 5mi (8km) away. A 1000BASE-LX is a type of Ethernet standard that supports data transmission at 1 gigabit per second over single- mode fiber cables using long wavelength lasers. A single-mode fiber cable is a type of optical fiber cable that has a small core diameter and allows only one mode of light to propagate through it. A single-mode fiber cable can transmit data over long distances at high speeds, but it requires more expensive transceivers and connectors than multimode fiber cables. A plenum fiber cable is a type of optical fiber cable that has a special coating that prevents the spread of fire or toxic fumes in case of burning. A plenum fiber cable is suitable for installation in plenum spaces, which are areas used for air circulation in buildings, such as above ceilings or below floors.

• Question 427:

  A server administrator implemented a new backup solution and needs to configure backup methods for remote sites. These remote sites have low bandwidth and backups must not interfere with the network during normal business hours. Which of the following methods can be used to meet these requirements? (Select two).

  A. Open file

  B. Archive

  C. Cloud

  D. Snapshot

  E. Differential

  F. Synthetic full

  Correct Answer: BE

  Archive is a method of storing historical data that is not frequently accessed or modified. Archive can reduce the amount of data that needs to be backed up and save bandwidth and storage space. Differential is a method of backing up only

  the data that has changed since the last full backup. Differential can also save bandwidth and storage space, as well as speed up the backup process.

• Question 428:

  A data center environment currently hosts more than 100 servers that include homegrown and commercial software. The management team has asked the server administrator to find a way to eliminate all company-owned data centers. Which of the following models will the administrator most likely choose to meet this need?

  A. SaaS

  B. Private

  C. Public

  D. Hybrid

  Correct Answer: C

  A public cloud model will most likely meet the need of eliminating all company-owned data centers. A public cloud is a type of cloud computing service that is provided by a third-party vendor over the internet. A public cloud offers scalability, flexibility, and cost-effectiveness for hosting servers and applications, as the customers only pay for the resources they use and do not have to maintain their own infrastructure. A public cloud can also provide high availability, security, and performance for the servers and applications, as the vendor manages the underlying hardware and software. A public cloud can support various types of services, such as software as a service (SaaS), platform as a service (PaaS), or infrastructure as a service (IaaS).
