A user reports that a software application functioned as expected the previous day, but this morning, the user is unable to launch the application.
Which of the following describe what the technician should do next?
- A . Research the symptoms
- B . Identify any changes the user has made
- C . Determine which steps need to be performed.
- D . Check the vendor’s website for guidance.
B
Explanation:
Identifying changes made to the system is the next step to troubleshoot why an application no longer launches, as recent changes often cause such issues.
Why Not A (Research the symptoms): Research is broader and should come after identifying changes.
Why Not C (Determine which steps need to be performed): This comes after identifying the issue.
Why Not D (Check the vendor’s website): This is a later step if further guidance is needed.

Which of the following display technologies typically provides the highest contrast?
- A . IPS
- B . OLED
- C . TN
- D . VA
B
Explanation:
OLED (Organic Light-Emitting Diode) technology can turn off individual pixels completely, producing “true black” and resulting in the highest contrast ratios compared to other display types.
From CompTIA A+ 220-1101 Official Study Guide, Objective 3.1 C Display types and features:
“OLED displays provide superior contrast by emitting light per pixel, allowing perfect black and extremely high contrast ratios.”

- A . Lightning interface
- B . Port replicator
- C . USB hub
- D . Bluetooth

A new directive mandates the use of a security component to securely allow users to authenticate to systems, access sensitive data, and enter the office. The component must provide an additional factor of authentication alongside user accounts and cannot be something the user o.
Which of the Mowing components best meets these requirements?
- A . Fingerprint reader
- B . Smart card
- C . Secure token
- D . NFC scanner
B
Explanation:
A smart card provides an additional factor of authentication by storing secure credentials, such as certificates, that cannot be guessed or replicated. It complements user accounts and is "something you have".
Why Not A (Fingerprint reader): This is "something you are", but the scenario specifically requires a physical token.
Why Not C (Secure token): Secure tokens are also valid but may not integrate as seamlessly into multi-factor authentication for physical and system access.
Why Not D (NFC scanner): An NFC scanner is a device and not a token itself; it reads cards or other credentials.

Which of the following DNS records would an administrator change to redirect email flow?
- A . MX
- B . TXT
- C . SPF
- D . CNAME
A
Explanation:
AnMX (Mail Exchange) record defines which mail servers are responsible for receiving email for a domain. If you want to change or redirect email traffic, the MX record must be updated with the correct server information.
Option B (TXT): Stores text-based info ― used for SPF, DKIM, etc.
Option C (SPF): Part of email authentication stored in a TXT record; doesn’t redirect traffic.
Option D (CNAME): Alias for another domain name ― not used for email routing. CompTIA A+ Core 1 Exam Objective

A customer reports that the output from their thermal receipt printer has vertical white lines.
Which of the following would most likely resolve this issue?
- A . Replacing the ink cartridge
- B . Using the correct paper type
- C . Installing a maintenance kit
- D . Cleaning the heating element
D
Explanation:
Thermal printers create images using a heated print head on specially coated thermal paper. Vertical white lines indicate that part of the heating element is dirty or blocked, preventing heat transfer to the paper. Cleaning the print head (heating element) will restore full functionality.
Option A: Thermal printers do not use ink or toner, so this is not applicable.
Option B: Wrong paper could cause blank output, but consistent vertical lines point to the print head.
Option C: Maintenance kits are typically for laser printers, not thermal printers.

A user’s wireless headset shows a "connected" status when turned on, but the Bluetooth list on the user’s phone shows that the headset is "not connected.".
Which of the following should the technician do?
- A . Enter the PIN.
- B . Turn off Wi-Fi.
- C . Re-pair the devices.
- D . Enable Bluetooth.
C
Explanation:
When a device shows as not connected even though it previously paired, the most effective action is tore-pair the devices. This resets the Bluetooth connection, clears any corruption in pairing profiles, and re-establishes communication.
Option A: Entering a PIN is only relevant during initial pairing and may not be prompted again.
Option B: Turning off Wi-Fi doesn’t typically affect Bluetooth; they operate on similar frequencies but don’t conflict this way in normal use.
Option D: If Bluetooth were disabled, the device wouldn’t appear at all, not just show as “not connected.”

Which of the following networking devices will most likely need to be installed in between the ISP running DOCSIS and the LAN in a SOHO environment?
- A . Switch
- B . Firewall
- C . Cable modem
- D . Router
- E . Access point
C
Explanation:
Comprehensive and Detailed Step-by-Step
To determine the correct device, we need to understand how a DOCSIS (Data Over Cable Service Interface Specification) network functions in a Small Office/Home Office (SOHO) environment:
C. Cable Modem:
A cable modem is required to convert the signal provided by the ISP (Internet Service Provider) over a DOCSIS network into a format that is usable by the local area network (LAN).
DOCSIS is a standard for high-speed internet over cable television infrastructure, and the cable modem acts as the gateway between the ISP’s coaxial network and the LAN.
Without the cable modem, devices in the LAN would not be able to access the internet.

Incorrect Options:
A technician is troubleshooting stylus issues on identical, company-provided tablets. Users can purchase their own accessories. Some users have no issues, but others report that their styluses charge intermittently and die frequently.
Which of the following is the most likely cause of this issue?
- A . Certain cases are causing charging issues.
- B . The tablets need to be updated.
- C . Some of the tablets have manufacturing defects.
- D . The malfunctioning styluses need firmware updates.
A
Explanation:
The most likely cause is third-party or ill-fitting cases obstructing the contact between the stylus and the tablet charging mechanism. Some cases may not be designed with stylus charging in mind, particularly if users are purchasing their own accessories.
Option B: A software update might fix OS-related issues, but would not typically affect physical charging.
Option C: If some devices had defects, the issue would likely be consistent, not isolated to some users.
Option D: Firmware issues could be a factor but are less likely than physical obstructions when users are using different accessories.

An end user’s domain password expires while they are working from home.
The end user tries to reset the password using Ctrl+Alt+Delete and then receives the following message:
Configuration information could not be read from the domain controller, either because the machine is unavailable or because access is denied.
Which of the following will resolve this issue?
- A . Restart the computer.
- B . Connect to the VPN.
- C . Reset the account in Active Directory.
- D . Join the Wi-Fi network.
B
Explanation:
To change a domain password from a remote location, the system must communicate with the domain controller. Since the user is working from home, they need to connect to the corporate VPNto establish that secure connection. Without it, the password change cannot be authenticated.
Option A: Restarting will not resolve the lack of connection to the domain controller.
Option C: Resetting the password in AD could help, but doesn’t let the user reset it themselves.
Option D: The user may already be on Wi-Fi; the issue is with connecting to the corporate network, not local.
