• Question 231:

  Which of the following describes the difference between a DNS server and a DHCP server?

  A. DNS is used for address translation, while DHCP is used for IP address assignment.
  B. DNS is used for routing, while DHCP is used for name resolution.
  C. DNS only assigns private IP addresses, while DHCP only assigns public IP addresses.
  D. DNS is used to route traffic between networks, while DHCP is used to allocate subnets.
  A. DNS is used for address translation, while DHCP is used for IP address assignment.

  ---

  Explanation

  DNS stands for Domain Name System, and it is a network service that translates human-readable names (such as www.google.com) into numerical IP addresses (such as 172.217.14.206) that identify the location of the web servers on the internet. DNS also allows reverse lookup, which means finding the domain name associated with a given IP address. DNS servers are responsible for maintaining a database of domain names and their corresponding IP addresses, and responding to queries from clients who want to resolve a name to an address or vice versa12. DHCP stands for Dynamic Host Configuration Protocol, and it is a network service that automatically assigns IP addresses and other network configuration parameters (such as subnet mask, default gateway, DNS server, etc.) to devices that join a network. DHCP servers are responsible for managing a pool of IP addresses and leasing them to clients for a specified duration. DHCP servers also renew or release the IP addresses when the lease expires or the client disconnects from the network34. The difference between DNS and DHCP is that DNS is used for address translation, which means converting domain names to IP addresses and vice versa, while DHCP is used for IP address assignment, which means providing IP addresses and other network settings to devices that need to communicate on a network.

• Question 233:

  When a user tries to print a document on a laser printer, vertical lines appear on the printout. Which of the following should the technician replace?

  A. Mirror
  B. Fuser
  C. Drum
  D. Toner
  C. Drum

  ---

  Explanation

  Vertical lines on printouts are often caused by a worn-out or damaged drum. Replacing the drum unit should resolve the issue.

• Question 234:

  Which of the following peripheral types is MOST likely to be used to input actions into a PC?

  A. Webcam
  B. Mouse
  C. Monitor
  D. Optical drive
  B. Mouse

  ---

  Explanation

• Question 235:

  Which of the following network devices converts fiber network signals from light into electric signals that can be used by a Wi-Fi router?

  A. Hub
  B. PoE
  C. ONT
  D. NIC
  C. ONT

  ---

  Explanation

  An ONT, or Optical Network Terminal, is a device that converts fiber network signals from light into electric signals that can be used by a Wi-Fi router. An ONT is an interface between the fiber optic network that carries optical signals and the

  devices that use electrical signals, such as routers, telephones, or computers. An ONT is similar to a modem for fiber internet, as it allows the devices to communicate with the internet service provider (ISP) and access the internet.

• Question 236:

  A systems administrator is working to ensure access to corporate laptops is limited to authorized users. The administrator has already implemented a password policy. Which of the following would be the best option to help the administrator secure the corporate resources?

  A. Trusted Platform Module
  B. Biometric scanner
  C. Laptop lock
  D. Encryption
  B. Biometric scanner

  ---

  Explanation

  The best option to help the administrator secure the corporate resources is

  B. Biometric scanner.

  A biometric scanner is a device that can authenticate a user's identity based on their physical or behavioral characteristics, such as fingerprint, iris, face, voice, or signature. A biometric scanner can provide a high level of security and convenience for accessing corporate laptops, as it can prevent unauthorized users from accessing the devices and eliminate the need to remember passwords . The other options are not the best options for this scenario. A Trusted Platform Module (TPM) is a chip that can store encryption keys and other sensitive data on a laptop. A TPM can enhance the security of data and devices, but it does not limit access to authorized users by itself. A TPM can work with a password or a biometric scanner to provide multifactor authentication . A laptop lock is a device that can physically secure a laptop to a desk or other object using a cable and a lock. A laptop lock can deter theft or tampering, but it does not prevent unauthorized users from accessing the laptop if they have the password or the key. Encryption is a process that can protect data on a laptop by transforming it into an unreadable format using a key. Encryption can prevent unauthorized users from accessing or modifying the data, but it does not prevent them from accessing the laptop itself.

• Question 237:

  A bank wants to leverage cloud computing but would like a cloud solution in which infrastructure is isolated from other businesses. Which of the following cloud models would BEST address the bank's need?

  A. Public
  B. Hybrid
  C. Private
  D. Community
  C. Private

  ---

  Explanation

  A private cloud is a cloud computing model that provides services and resources to a specific organization or group over a private network. A private cloud can offer more security and control than other cloud models, as well as customized infrastructure that suits the organization's needs. A bank would most likely choose a private cloud model to leverage cloud computing while maintaining isolation from other businesses. A public cloud is a cloud computing model that provides services and resources to anyone over the internet. A hybrid cloud is a combination of public and private cloud services that share data and resources.

• Question 238:

  A technician is setting up a new desktop computer and will be installing the hard drive directly on the motherboard without using cables to connect it. Which of the following will the technician be installing?

  A. Thunderbolt
  B. eSATA
  C. M.2
  D. SCSI
  C. M.2

  ---

  Explanation

  M.2 is a form factor for solid-state drives (SSDs) that enables direct attachment to the motherboard without the need for cables. Thunderbolt is a high-speed interface that supports data transfer, video output, and charging. eSATA is an external interface for connecting SATA devices. SCSI is an older interface standard for connecting hard drives, printers, and other peripherals. Installing a hard drive directly on the motherboard without using cables is usually done with an M.2 slot.

• Question 239:

  A technician is configuring a new CAD workstation that has four large hard drives. The workstation will be used to edit large, critical files, so the storage configuration should be both fast and redundant. Which of the following RAID levels BEST meets these requirements?

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

  ---

  Explanation

  RAID 10 combines the benefits of RAID 0 and RAID 1. It uses a striped configuration across multiple disks (similar to RAID 0) to provide high-speed read and write access. Additionally, it also mirrors the striped array onto a second set of drives (similar to RAID 1), providing redundancy in case of a drive failure.

• Question 240:

  A user complains that print jobs remain in the printer queue. A technician sends a ping command to the printer, and the printer replies successfully. The paper trays are full, and toner levels are okay.

  Which of the following is a reason the print jobs are getting stuck in the queue?

  A. Theprinter is disconnected from the network.
  B. Thefirst job in thequeue is waiting for paper inthemanual feed tray.
  C. Thepaper size forthe last job in the queue is not available.
  D. Theprint queue isunable to locate the printer.
  B. Thefirst job in thequeue is waiting for paper inthemanual feed tray.

  ---

  Explanation

  When print jobs remain stuck in the printer queue despite successful network communication (indicated by successful ping replies) and no issues with paper supply or toner levels, a common reason can be that the first job in the queue requires manual intervention, such as paper to be fed into a manual feed tray. Printers often pause the entire print queue if the first job requires a specific type of paper or manual insertion that hasn't been addressed, preventing subsequent jobs from processing.
