  A technician is working on a help desk ticket for a user who wants the filament replaced in a 3-D printer. Which of the following should the technician do to remove the old filament and load the new one?

  A. Preheat the nozzle to melting temperature.

  B. Cut a sharp angle on the end of the strand.

  C. Push the filament along until resistance is felt.

  D. Withdraw the filament and remove the spool.

  Correct Answer: D

  A technician is working on a help desk ticket for a user who wants the filament replaced in a 3-D printer. To remove the old filament and load the new one, the technician should preheat the nozzle to melting temperature. After the nozzle is heated, the technician should withdraw the filament and remove the spool. Then, cut a sharp angle on the end of the new strand, and push it along until resistance is felt.

• Question 163:

  A user is looking for a way to increase the total RAM in a system without upgrading the hardware. Which of the following should the user perform to complete this task?

  A. Run a burn-in application

  B. Create a VM.

  C. Install hardware-tuning software.

  D. Set up virtual memory.

  Correct Answer: D

  Virtual memory is a software-based memory management system that allows a computer to use hard disk storage space as RAM. This can be used to increase the total RAM in a system without upgrading the hardware. To set up virtual memory, the user should go to the System Properties window and select the Advanced tab. In the Performance section, click on the Settings button, which will open the Performance Options window. Then, click on the Advanced tab and click on the Change button in the Virtual memory section. Finally, select the option to Automatically manage paging file size for all drives, and then click OK to save the changes.

• Question 164:

  A company wants to give third-party developers access to the corporate network through desktop environments that the company can control. Which of the following can BEST achieve these requirements?

  A. Sandbox

  B. VDI

  C. Private cloud

  D. Saas

  Correct Answer: B

  VDI is a technology that allows a company to provide desktop environments to third-party developers while still maintaining control over the corporate network. VDI creates virtual desktops on a remote server, and each user gets their own desktop environment that is isolated from the other users. This allows the company to maintain control over the corporate network, as the virtual desktops are not directly connected to the corporate network.

• Question 165:

  A user is researching hard drives to upgrade a PC and has decided to purchase a NVMe drive. Which of the following Should the user confirm are available on the PC before making the purchase? (Select TWO).

  A. SATA

  B. M.2

  C. PCIe

  D. SAS

  E. SCSI

  F. DRAM

  Correct Answer: BC

  NVMe (Non-Volatile Memory Express) drives are high-speed solid-state drives that utilize the PCIe (Peripheral Component Interconnect Express) interface to connect to the motherboard. Before purchasing an NVMe drive, the user should confirm that the PC has an available M.2 slot for the drive and that the PC has a PCIe interface for the M.2 slot. SATA (Serial ATA) is an older interface for hard drives and is not compatible with NVMe drives. SAS (Serial Attached SCSI) is a newer interface for hard drives and is typically used for enterprise-level storage systems. SCSI (Small Computer System Interface) is a parallel interface for hard drives that is primarily used in high-end workstations and servers. DRAM (Dynamic Random Access Memory) is a type of memory commonly used in computers, but it is not relevant to the storage of data on a hard drive. Reference: CompTIA A+ Core 1 uide, page 267.

• Question 166:

  Which of the following allows a switch to be divided into separate logical networks?

  A. VLAN

  B. SSL VPN

  C. NAT

  D. RADIUS

  Correct Answer: A

  A Virtual LAN (VLAN) is a network topology that allows a switch to be divided into separate logical networks. This allows for the creation of multiple broadcast domains within a single physical network, improving network segmentation and security. With VLANs, you can segment your network so that different departments, applications, or users are isolated from each other, improving network security and performance.

• Question 167:

  Which of the following is the SAFEST way to replace RAM on a server that has a redundant power supply?

  A. Unplug one power cable.

  B. Verify the RAM temperature.

  C. Utilize a grounding strap.

  D. Replace the RAM while the server is running.

  Correct Answer: C

  Utilizing a grounding strap is the safest way to replace RAM on a server that has a redundant power supply. This ensures that no static electricity is transferred to any of the server components, which could cause permanent damage. The other options are not the correct methods for replacing RAM. Unplugging one power cable is not recommended, as it could cause the server to go offline and disrupt any services that are running. Verifying the RAM temperature is not necessary and does not provide any additional safety measures, and replacing the RAM while the server is running is not recommended, as it could cause system instability.

• Question 168:

  A customer called the help desk to request information about how to increase the volume on a laptop using only a keyboard. Which of the following keys would MOST likely allow this to be done?

  A. Alt

  B. Fn

  C. Tab

  D. Ctrl

  Correct Answer: B

  To increase the volume on a laptop using only a keyboard, a user can press and hold down the Fn key while pressing one of the function keys (usually F1-F12) that has an icon representing volume up.

• Question 169:

  A systems administrator is attempting to resolve a ticket regarding an issue with an email server. The administrator is covering for a coworker who was previously working on the ticket. The coworker already gathered facts about the issue and spoke with users concerning their missing emails. The coworker also discovered the email server's retention policy was updated shortly before users first noticed the issue.

  Which of the following should the systems administrator do NEXT to resolve the email issue?

  A. Escalate the ticket to a higher level to resolve the email server issue.

  B. Test a theory to determine the cause of the email server issue.

  C. Establish a theory of probable cause for the email server issue.

  D. Create a plan of action to resolve the email server issue.

  Correct Answer: C

  Before attempting to resolve the issue, it is important to first determine the cause or probable cause of the issue, so that a plan of action can be developed. In this case, the fact that the retention policy was updated shortly before users first noticed the issue suggests that this could be the cause of the issue. The systems administrator should investigate this further to determine if this is indeed the cause of the email server issue.

• Question 170:

  An organization keeps receiving spam that appears to come from its own domain No accounts have been compromised. Which of the following will BEST mitigate this issue?

  A. DNS

  B. S/MIME

  C. SPF

  D. SSiD

  Correct Answer: C

  The BEST solution to mitigate spam that appears to come from an organization's own domain is to implement SPF (Sender Policy Framework). SPF is an email validation protocol designed to detect and prevent email spoofing, which is a common tactic used by spammers. By publishing SPF records in the organization's DNS (Domain Name System), the recipient's mail server can check if an incoming email originated from a valid source. If the email fails SPF authentication, it can be blocked or flagged as spam. Therefore, SPF helps to prevent email spoofing and mitigate the risk of spam coming from an organization's own domain
