A technician is replacing the RAM on an entry-level server with hot-swappabte components. Which of the following should the technician do NEXT?
A. Replace the RAM while the server is at a cool temperature
B. Replace the RAM while the server is running
C. Power down the server completely and then replace the RAM
D. Verify that the OS supports hot swapping the RAM
Explanation: Verify that the OS supports hot swapping the RAM. Before replacing the RAM on an entry-level server with hot-swappable components, the technician should verify that the operating system supports hot swapping of RAM.

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.
CompTIA A+ Exam Reference: Core 1 (220-1101), Section 2.6, IP addressing.
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.
