A technician just decommissioned an on-premises email server. Users are now complaining that scan-to-email is not working. Which of the following actions should the technician most likely take?
A. Configure an email relay on an existing server.
B. Configure a secure, cloud-based email relay.
C. Bring the old email server back into production.
D. Configure a new email server from scratch.
Explanation:
Since the on-premises email server has been decommissioned and users are experiencing issues with scan-to-email functionality, the best solution would be to configure an email relay. An email relay server can accept emails from devices like printers and forward them to the correct destination (such as a cloud-based email service). This avoids the need to bring back the old server or set up a new one.
✑ A. Configure an email relay on an existing server: This allows the scanner to send
emails through another server, ensuring the functionality is restored.
Why the other options are incorrect:
✑ B. Configure a secure, cloud-based email relay: While a cloud-based solution could work, configuring an email relay on an existing server is a more immediate and likely solution.
✑ C. Bring the old email server back into production: This is unnecessary and would defeat the purpose of decommissioning it.
✑ D. Configure a new email server from scratch: Setting up a new email server would be time-consuming and not necessary in this situation.
This is part of the Networking and Troubleshooting domain in the CompTIA A+ Core 1 exam.
A department sends in a ticket to report a printer is not working. The responding technician sees paper stuck to the fuser, which is much hotter than normal. The (user was just installed a few weeks ago. as indicated by the service history. Which of the following should the technician do NEXT?
A. Disconnect the printer power for troubleshooting
B. Install a printer roller kit.
C. Replace the overheating fuser.
D. Replace the paper with thicker paper stock.
Explanation:
The first step in troubleshooting a printer issue is to disconnect the printer power to avoid
electric shock or further damage to the printer. The technician can then inspect the fuser
and determine if it needs to be replaced or repaired. Installing a printer roller kit or replacing
the paper with thicker paper stock will not solve the problem of the overheating fuser.
Replacing the fuser without disconnecting the power is dangerous and not recommended.

A salesperson is unable to reach the internet from a home office PC A support technician wants to verify the router is receiving a valid public IP address Which of the Wowing is a valid public IP address in this scenario?
A. 10.254.128.11
B. 66.157.195.20
C. 172.16.0.30
D. 192.168 1.50
Explanation: A valid public IP address must fall outside the private IP address ranges:
✑ 10.0.0.0 to 10.255.255.255
✑ 172.16.0.0 to 172.31.255.255
✑ 192.168.0.0 to 192.168.255.255
66.157.195.20 is outside these ranges, making it a public IP address.
✑ Why Not A, C, D: These IPs fall within private IP address ranges.

To control costs a company provides a limited number or users with company phones One of these users opens a support ticket because the phone no longer allows internet Drowsing over a cellular connection The user acknowledges that the phone worked before the user's child streamed several movies using the device Which of the following describes why the phone cannot browse the Internet?
A. The child accidentally connected to a neighbor's WLAN
B. The company's group policy disabled the device
C. The device has a data cap and has reached that limit
D. The device's plan has been unpaid
Explanation:
It is common for companies to place a data cap on the devices they provide to their
employees, to control costs. If a user has exceeded the data cap, the phone may no longer
allow internet browsing over a cellular connection. This is usually because the cellular data
usage has exceeded the allotted amount for the particular plan the device is on, and the
service provider has temporarily suspended the data connection.
It is unlikely that the child accidentally connected to a neighbor's WLAN because this would
not affect the cellular data connection. Similarly, it is unlikely that the company's group
policy has disabled the device, as this would likely affect all devices under the same policy.
If the device's plan has been unpaid, the service provider would likely temporarily suspend all services, not just the cellular data connection.
An end user is having trouble printing from an application. The text on the page is unreadable. However, the application prints successfully from a newer computer. Which of the following should be done next?
A. Reinstall the printer.
B. Adjust the print tray.
C. Update the printer driver.
D. Change the toner.
Vertical streaks are appearing on the output of a laser printer. Which of the following items is the MOST likely cause?
A. Roller
B. Drum
C. Transfer belt
D. Ribbon
Explanation: Vertical or horizontal lines—Marks that appear in the same place (referred to as repetitive defects) are often due to dirty feed rollers (note that there are rollers in the toner cartridge and fuser unit too) or a damaged or dirty photosensitive drum. Vertical streaks on a laser printer output are usually caused by a damaged or worn-out drum, which is responsible for transferring toner to the paper. If the drum is damaged, toner may accumulate on certain parts of the drum, leading to streaks on the printed output.
A technician is selecting a power supply for a new computer. There will be a large number of connected devices that must be powered by USB. Which of the following specifications should the technician prioritize?
A. Modular connector count
B. 5V amperage
C. 20+4 power connector
D. Energy efficiency
Explanation: USB devices rely on 5V output from the power supply, so the amperage rating at 5V is critical to ensure enough power is available for multiple USB devices. A modular connector count affects cable management, while a 20+4 power connector is standard for motherboard connections. Energy efficiency impacts overall power usage but is not specific to the needs of USB devices. This matches CompTIA A+ Core 1 objectives regarding power supply selection based on device requirements.
A new version of Windows was released and a piece of software vital to the engineering department will not run on the new version. Which of the following is the BEST option to enable this department to be able to continue using this software?
A. Do not upgrade any workstations within the organization
B. Upgrade all workstations and provide a virtual environment for the legacy software
C. Upgrade all workstations except those used by the engineering department
D. Purchase new workstations for the engineering department
Explanation: Upgrading all workstations and providing a virtual environment for the legacy software is the best option, as it allows the engineering department to continue using the vital software while also upgrading to the latest version of Windows. This also ensures that the rest of the organization can take advantage of the latest software and security features.
A company uses vital legacy software that does not run in the current OS version Which of the following will best support the software while keeping the OS current?
A. Shared resources
B. System sandbox
C. Test development
D. Application visualization
Explanation: Application virtualization allows legacy software to run in a virtualized environment while the operating system remains current. It isolates the application from the OS, ensuring compatibility without downgrading the OS.
✑ Why Not A (Shared resources): This relates to resource sharing, not application
compatibility.
✑ Why Not B (System sandbox): Sandboxes isolate applications for security testing, not compatibility.
✑ Why Not C (Test development): Test environments are used for development, not running legacy applications.
A hardware technician is configuring a laptop, and the network administrator requires the network settings to be static. The technician successfully pings the servers by IP address but cannot ping the UNC path. Which of the following is the cause of this issue?
A. Domain Name System
B. Gateway
C. Subnet
D. IP address
Explanation: The cause of the issue is likely due to a DNS resolution issue. While the technician can ping the servers by IP address, they cannot ping the UNC path, indicating an issue with the name resolution. This can be resolved by configuring the correct DNS server settings.
An SAS RAID array has severely degraded and gone offline A systems administrator examines the syslog, and the point of failure is not obvious. Which of the following techniques should the administrator use to identify the issue (Select two).
A. Run a magnet over each drive.
B. Check if one of the drives is not level
C. Listen for clicking and grinding noises
D. Check the OS logs
E. Update the RAID controller firmware.
F. Check the historical SMART data
Explanation:
✑ Clicking and grinding noises indicate mechanical drive failure.
✑ SMART data provides insights into the health and status of drives, helping identify failing components in the RAID array.
✑ Why Not A (Run a magnet): This would damage drives.
✑ Why Not B (Check if one drive is not level): Physical leveling is irrelevant.
✑ Why Not D (Check OS logs): OS logs may provide limited information for RAID arrays.
✑ Why Not E (Update RAID controller firmware): While important, it does not diagnose drive failure.
