  The quickest way to resolve the issue is to install a Power over Ethernet (PoE) injector to provide power to the IP phone. An unmanaged switch does not provide PoE, so an injector is needed to power the phone.

• Question 314:

  A system administrator has been tasked with allowing SMTP traffic through the system's host-based firewall. Which of the following ports should the administrator enabled?

  A. 23
  B. 25
  C. 80
  D. 161
  B. 25

  ---

  Explanation

  SMTP (Simple Mail Transfer Protocol) uses port 25 to send email messages between servers12. SMTP uses port 25 to send email messages between mail servers. Therefore, the system administrator should enable port 25 to allow SMTP traffic through the host-based firewall.

• Question 315:

  A user is installing a new display on a desktop computer that only has a single DVI port for video input and a single HDMI port tot video output.

  Which of me following does the technician need to complete the setup?

  A. DigitaMo-analog converter
  B. A/v switcher
  C. DisplayPort to HDMI adapter
  D. DVI to HDMI cable
  D. DVI to HDMI cable

  ---

  Explanation

  The technician will need to connect the DVI port on the computer to the new display's HDMI port. To do this, a DVI to HDMI cable will be needed. This type of cable will allow the computer's DVI video signal to be transmitted to the new

  display's HDMI port. A digital-to-analog converter (DAC) is used to convert a digital signal to an analog signal. An A/V switcher is used to switch between multiple audio and video sources and display them on a single monitor or display. A

  DisplayPort to HDMI adapter is used to convert a DisplayPort signal to an HDMI signal, but it is not necessary in this scenario as the computer has a DVI port and not a DisplayPort.

• Question 316:

  A company has implemented a policy that allows employees to use personal devices to perform work duties. Which of the following policies should the technician activate to protect company information?

  A. MFD
  B. MAM
  C. MFA
  D. MDM
  D. MDM

  ---

  Explanation

  MDM (Mobile Device Management) is a policy that allows the technician to remotely manage, secure, and monitor the personal devices that employees use for work purposes. MDM can enforce security settings, such as passwords, encryption, and antivirus software, on the personal devices. MDM can also remotely wipe or lock the devices in case of loss, theft, or termination of employment. MDM can protect company information by preventing unauthorized access, data leakage, or malware infection on the personal devices.

• Question 317:

  A systems administrator at a school is setting up computing devices with keyboards. All the devices need to have an identical build. The administrator knows from prior experience that students often spill food or drinks on their devices. Which of the following is the BEST option for the administrator to use?

  A. Thick clients
  B. Thin clients
  C. Laptops
  D. Workstations

• Question 318:

  A technician is troubleshooting a laptop that sometimes fails to charge. The technician has already tested the power adapter and determined the connection is good. Which of the following is the most likely cause of the issue?

  A. Defective DC jack
  B. Failing cooling fan
  C. Bad memory
  D. Overheating CPU
  A. Defective DC jack

  ---

  Explanation

  If the power adapter has been tested and found to be functioning correctly, and the connection is secure, the next likely point of failure would be the DC jack. If the DC jack is defective, it can prevent the laptop from receiving power or charging the battery properly. Replacing or repairing the DC jack would likely resolve the charging issue.

• Question 319:

  A user called the help desk to request assistance with selecting appropriate storage to back up a large collection of DVDs and photos in the most economical way. Which of the following should the help desk recommend?

  A. 5,400rpm HDD
  B. M.2 NVMe SSD
  C. SAS RAID array
  D. Optical media
  D. Optical media

  ---

  Explanation

  Optical media, such as CDs, DVDs, or Blu-ray discs, are a suitable choice for backing up a large collection of DVDs and photos in the most economical way. Optical media are inexpensive, widely available, and have a long shelf life. They can store large amounts of data, up to 50GB on a dual-layer Blu-ray disc, and can be easily labeled and organized. Optical media are also less prone to mechanical failure, data corruption, or accidental deletion than hard disk drives (HDDs) or solid state drives (SSDs). The other options are not as economical or suitable for this purpose. A 5,400rpm HDD is a slow and noisy type of HDD that has moving parts that can wear out or break. A HDD also consumes more power and generates more heat than an SSD. A M.2 NVMe SSD is a fast and compact type of SSD that uses a PCIe interface to transfer data. However, an SSD is more expensive than an HDD or optical media, and has a limited number of write cycles before it degrades. A SAS RAID array is a complex and costly system that uses multiple HDDs or SSDs connected by a Serial Attached SCSI (SAS) interface to provide redundancy, performance, or both. A RAID array requires a RAID controller, a compatible motherboard, and a dedicated power supply.

• Question 320:

  A user reports that when pressing a radio button on a tablet, an item a couple of inches to the right of the pressed button gets selected instead. Which of the following components may need to be replaced?

  A. Gyroscope
  B. Battery
  C. Digitizer
  D. Glass
  C. Digitizer

  ---

  Explanation

  A digitizer is a component that converts the touch input on a tablet screen into digital signals that can be processed by the device. A digitizer consists of a thin layer of transparent material that covers the glass screen and has sensors that detect the position and pressure of the touch. If the digitizer is damaged, misaligned, or poorly calibrated, it can cause inaccurate touch input, such as selecting the wrong item or not responding at all12. Therefore, the most likely cause of the issue in this scenario is a faulty digitizer that may need to be replaced. The other components are not directly related to the touch input functionality of the tablet. A gyroscope is a sensor that measures the orientation and rotation of the device3. A battery is a power source that supplies electricity to the device4. A glass is a protective layer that covers the screen and prevents scratches and cracks5.
