• Question 62:

  Which of the following involves installing an application on a server so several users can run the application concurrently without the need for local installation?

  A. Client virtualization
  B. Software as a service
  C. Sandboxing
  D. Embedded software
  B. Software as a service

  ---

  Explanation

  The term "Software as a Service" (SaaS) refers to a cloud computing model where software applications are hosted on remote servers and made available to users over the internet. In this model, users can access and use the software via a web browser or thin client without needing to install the application locally on their devices.

  When an application is deployed as a SaaS solution, it is installed and maintained on servers centrally managed by the service provider. Multiple users can then access and use the application simultaneously, each with their own unique user accounts and data, without the need for individual installations on their devices. This centralized approach to software deployment and access enables efficient sharing and collaboration among users while minimizing the overhead associated with local installations and maintenance.

  A technician is installing new power supplies for the application engineering team's workstations. The management team has not yet made a decision about installing dual graphics cards, but they want to proceed with the project anyway. Which of the following power supplies would provide the BEST solution?

  A. 1000W 24-pin modular power supply
  B. 220VAC 9000J surge protector
  C. 500W redundant power supply
  D. 2000VA uninterruptible power supply
  A. 1000W 24-pin modular power supply

  ---

  Explanation

  A 1000W 24-pin modular power supply provides enough power to support a dual graphics card configuration, which requires a significant amount of power. A modular power supply allows the technician to connect only the cables that are necessary for the current configuration, reducing cable clutter and improving airflow inside the case. This makes it easier to install and maintain the power supply.

• Question 65:

  A drive failed on a server that was leveraging a RAID disk configuration. The server administrator would like to rebuild the array so it can withstand a potential multidrive failure in the future. Which of the following RAID configurations will the administrator MOST likely select?

  B. 1
  C. 5
  D. 10
  D. 10

  ---

  Explanation

  RAID stands for Redundant Array of Independent Disks, which is a technology that combines multiple disks into a logical unit to improve performance, reliability, or both. There are different types of RAID levels that use different methods of

  data distribution and redundancy.

  RAID 0 is a level that stripes data across multiple disks without any redundancy. It offers the highest performance but no fault tolerance. If any disk fails, the entire array is lost. RAID 1 is a level that mirrors data across two disks. It offers the

  lowest performance but the highest fault tolerance. It can survive the failure of one disk. RAID 5 is a level that stripes data across multiple disks with parity information. It offers a balance between performance and fault tolerance. It can survive

  the failure of one disk, but not two or more disks.

  RAID 10 is a level that combines RAID 1 and RAID 0. It creates a striped array of mirrored pairs. It offers high performance and high fault tolerance. It can survive the failure of one disk in each pair, or multiple disks in different pairs.

  Therefore, if the server administrator wants to rebuild the array to withstand a potential multidrive failure in the future, RAID 10 is the most likely choice.

• Question 66:

  The output from print jobs a user submitted to a laser printer is missing the color yellow. The user has already attempted a cleaning cycle. Which of the following parts most likely needs to be replaced?

  A. Fuser
  B. Ink cartridge
  C. Imaging drum
  D. Toner tank
  E. Resin
  C. Imaging drum

  ---

  Explanation

  An imaging drum is a component of a laser printer that transfers the toner to the paper. It is sensitive to light and can wear out over time, resulting in poor print quality or missing colors. If the cleaning cycle does not resolve the issue, the imaging drum may need to be replaced1. A fuser is a component of a laser printer that heats and melts the toner onto the paper. It does not affect the color output of the printer, but it can cause paper jams, smudges, or wrinkles if it is defective2. An ink cartridge is a component of an inkjet printer, not a laser printer. A laser printer uses toner, which is a dry powder, instead of ink, which is a liquid. An ink cartridge would not be compatible with a laser printer3. A toner tank is a container that holds the toner for a laser printer. It can be either integrated with the imaging drum or separate from it. If the toner tank is empty or low, the printer will display a warning message and the print quality will deteriorate. However, if only one color is missing, the problem is more likely with the imaging drum than the toner tank4. Resin is a material that is used in some types of 3D printers, not laser printers. Resin printers use a liquid resin that is cured by a light source to create solid objects. Resin has nothing to do with laser printing5.

• Question 67:

  Which of the following 802.11 Wi-Fi protocols utilizes the 5.0GHz frequency and has the BEST speed and reception?

  A. 802.11a
  B. 802.11 ax
  C. 802.11b/g/n
  D. 802.11n
  B. 802.11 ax

  ---

  Explanation

  802.11 ax is a wireless networking protocol that utilizes the 5.0GHz frequency and has the best speed and reception among the options given. 802.11 ax offers higher data rates, lower latency, increased capacity, and improved power

  efficiency than previous protocols. It is also known as Wi-Fi 6 or High Efficiency Wireless (HEW). 802.11a also uses the 5.0GHz frequency, but it is an older protocol that has lower speed and reception than 802.11 ax. 802.11b/g/n use the

  2.4GHz frequency, which is more crowded and prone to interference than the 5.0GHz frequency. 802.11n can use both frequencies, but it is also slower and less efficient than 802.11 ax.

• Question 68:

  A business purchased a new multifunction printer that will be used to photocopy documents with hundreds of pages. A technician is configuring the printer. Which of the following features should the technician ensure is set up?

  A. SMB
  B. PCL
  C. ADF
  D. SSH
  C. ADF

  ---

  Explanation

  Automatic document feeder (ADF) is a feature that allows a multifunction printer to photocopy documents with hundreds of pages automatically without requiring manual intervention. ADF scans multiple pages from a stack of documents and feeds them into the printer one by one. SMB is a network protocol that allows file sharing and printer access among different devices on a network. PCL is a printer language that controls how data is formatted for printing. SSH is a network protocol that allows secure remote access to another device over an encrypted connection.

• Question 69:

  A technician needs to configure a multifunction printer that will be used to scan highly confidential data, which must be securely distributed to a select group of executives.

  Which of the following options is the most secure way to accomplish this task?

  A. Set up the device to email the documentsto a group address.
  B. Make copies of the documents and have an office administrator manually distribute them.
  C. Implement badge access on the printer.
  D. Configure scanning to an SMB share withexecutive access.
  D. Configure scanning to an SMB share withexecutive access.

  ---

  Explanation

  Configuring scanning to a Secure Message Block (SMB) share specifically designated for executive access ensures that the scanned confidential documents are stored securely on a network drive with restricted access. SMB is a network file sharing protocol that allows applications on a computer to read and write to files and request services from server programs in a computer network. By setting up an SMB share with executive access, the data is centralized, making it easier to manage permissions and security settings. This method also utilizes the existing network infrastructure, allowing for scalability and integration with other security measures like encryption and authentication protocols.
