NEW QUESTION # 108
Which of the following is used to confirm that a physical port is working?
- A. Loopback plug
- B. Patch panel
- C. Crimper
- D. Network tap
Answer: A
Explanation:
A loopback plug is a diagnostic tool used to test whether a physical port such as an Ethernet NIC port or serial port is capable of sending and receiving its own signal. When inserted, it "loops" outgoing signals back into the device, confirming the port's transmit/receive functionality.
CompTIA A+ emphasizes loopback plugs as essential tools during hardware and network troubleshooting, especially when isolating physical port or NIC failures.
Network taps passively monitor traffic, crimpers attach RJ45 connectors to cables, and patch panels organize cabling none of these verify port-level functionality. Therefore, only a loopback plug can confirm that a port is working correctly by testing signal integrity and hardware responsiveness.
NEW QUESTION # 109
An office manager must scan a 300-page contract quickly. They are worried about scanning each page one at a time. Which feature will speed up the process?
- A. Duplexing
- B. Automatic document feeder
- C. Orientation configuration
- D. Flatbed scanner
Answer: B
Explanation:
CompTIA A+ details that an Automatic Document Feeder (ADF) allows multi-page documents to be scanned automatically without manually placing each sheet on the flatbed. This drastically increases scanning efficiency for large documents.
Flatbed scanners require manual placement for every page. Duplexing scans both sides of a page but does not feed multiple sheets by itself. Orientation configuration only affects image alignment.
The ADF is explicitly highlighted in the A+ study guide as the primary feature used in business environments when scanning high-volume documents efficiently.
Thus, the ADF is the correct solution because it automates page feeding and dramatically reduces scanning time, especially for hundreds of pages.

An end user reports that their laptop has a blank screen. A technician observes the keyboard lights are on, and the fan is running. Which of the following should the technician do next?
- A. Check the display ribbon cable.
- B. Contact vendor support
- C. Replace the inverter
- D. Connect to an external monitor
Answer: D
Explanation:
When a laptop powers on but the screen is blank, the quickest way to isolate the problem is to connect to an external monitor. This helps determine if the issue is with the laptop display or with the graphics subsystem.
From CompTIA A+ 220-1101 Official Study Guide, Objective 4.1 - Troubleshoot common hardware problems:

NEW QUESTION # 111
A technician receives a S.M.A.R.T. error on a PC. When the technician presses the Esc key, the PC continues to turn on without any further issues. Which of the following should the technician do next?
- A. Close the ticket.
- B. Replace the HDD.
- C. Update the PC's BIOS.
- D. Change the NIC.
Answer: B
Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology):
S.M.A.R.T. is a monitoring system integrated into modern HDDs and SSDs that detects and reports on various indicators of drive health and reliability.
A S.M.A.R.T. error indicates that the drive is showing signs of impending failure, even if the PC continues to boot and work normally for the time being.
Next Steps:
The appropriate action is to replace the hard drive (HDD) because a S.M.A.R.T. error is an early warning of possible hardware failure. Ignoring the warning could result in data loss if the drive fails completely.
The technician should also back up the user's data immediately to avoid losing critical information.
Incorrect Options:
B: Update the PC's BIOS: While keeping the BIOS updated is a good practice, it does not address the S.M.A.
R.T. error, which is specific to the HDD.
C: Close the ticket: Closing the ticket without resolving the issue would be improper, as the S.M.A.R.T. error is a hardware problem that needs to be addressed to prevent future data loss or downtime.
D: Change the NIC: The NIC (Network Interface Card) is unrelated to the storage system and would not resolve a S.M.A.R.T. error.
Key Takeaway:
A S.M.A.R.T. error is a critical indicator of HDD health issues, and the drive should be replaced as soon as possible. Backing up data is also essential.

NEW QUESTION # 112
Which of the following virtualization concepts is suitable for a development team that requires a bare minimum platform to run web applications with the capability to dispose and redeploy as needed?
- A. Containers
- B. Desktop virtualization
- C. IaaS
- D. SaaS
Answer: A
Explanation:
The correct answer is A. Containers.
According to CompTIA A+ Core 1 220-1201 objectives under Networking and Cloud/Virtualization Concepts:
* Containers provide lightweight, portable environments that package applications and their dependencies, allowing them to run consistently across multiple environments.
* Containers are ideal for development teams because they require minimal underlying infrastructure, can be quickly deployed or destroyed, and isolate applications from the host system, making it easier to manage multiple applications simultaneously.
Why the other options are incorrect:
* B. IaaS (Infrastructure as a Service): Provides virtualized hardware over the cloud but is more general- purpose; it includes virtual machines, storage, and networking, not minimal isolated application environments.
* C. SaaS (Software as a Service): Provides fully managed software to end-users; not intended for deploying custom web applications by a development team.
* D. Desktop virtualization: Provides virtual desktop environments to users; it does not provide a minimal, disposable platform for web application development.

NEW QUESTION # 114
A user ran out of USB ports on their laptop but wants to plug in more devices. What technology is best?
- A. Port replicator
- B. Near-field communication
- C. USB receiver
- D. Bluetooth
Answer: A
Explanation:
A port replicator expands the number and types of ports available to a laptop, including additional USB ports, video outputs, Ethernet, and more. CompTIA A+ identifies port replicators as solutions for users needing greater connectivity, especially when docking stations are unnecessary or unavailable.
Port replicators connect through a single USB or proprietary connector and provide multiple expansion ports instantly. This resolves the issue of limited USB availability without requiring hardware replacement.
NEW QUESTION # 115
A customer is using port 110 for email. However, the customer wants to upgrade to a more secure connection that automatically synchronizes with the server. Which of the following should the customer use?
- A. IMAP
- B. SMTP
- C. HTTPS
- D. SFTP
Answer: A
Explanation:
Port 110 is used by POP3, a protocol designed for downloading emails from a remote server to a local client.
POP3 does not inherently synchronize changes (such as read status, folder organization, or deletions) between devices. The customer wants a more secure connection that automatically synchronizes with the server, which directly aligns with the functions of IMAP (Internet Message Access Protocol).
IMAP typically uses port 143 for unencrypted connections and 993 for secure, encrypted connections (IMAPS). It is designed for modern email usage-supporting multi-device access, live synchronization across clients, and server-stored mail. When a user reads, deletes, or moves an email using IMAP, these changes are reflected on the server and visible on every device logged into the same account.
CompTIA A+ emphasizes that IMAP is preferred for users requiring constant synchronization, mobile access, and cloud-based email management, while POP3 is considered outdated. IMAP also supports secure, encrypted communication when paired with SSL/TLS.
HTTPS and SFTP do not handle email retrieval, and SMTP is a sending protocol, not a retrieval protocol.
Therefore, IMAP is the only correct and CompTIA-aligned upgrade option.
NEW QUESTION # 116
A technician needs to configure an MX record. Which of the following will the technician use?
- A. DNS server
- B. Proxy server
- C. Mail server
- D. Print server
Answer: A
Explanation:
The technician will configure the MX record on a DNS server. An MX, or Mail Exchange, record is a DNS resource record that identifies the mail server responsible for accepting email for a particular domain. It can also include a priority value so that sending systems know which mail server to contact first when multiple servers are available. Although the record points to a mail server, it is created and maintained within the domain's DNS zone rather than directly on the mail server. A proxy server intermediates network requests and is unrelated to DNS email-routing records. A print server manages printers and print queues and has no role in email delivery. Therefore, the DNS management interface or authoritative DNS server for the domain is where the technician must create or modify the MX record.
NEW QUESTION # 117
Which of the following allows a physical server to host multiple virtual machines?
- A. Hypervisor
- B. Sandbox
- C. SaaS
- D. Cross-platform virtualization
Answer: A
Explanation:
A hypervisor is software or firmware that allows multiple operating systems (virtual machines) to run on a single physical host. It manages the allocation of resources and isolation of each VM.
From CompTIA A+ 220-1101 Official Study Guide, Objective 3.7 - Virtualization concepts:

NEW QUESTION # 118
A user reports cursor issues on a company laptop. Technician finds a bulge under the trackpad. Which component should be replaced first?
- A. Battery
- B. Heat sink
- C. Motherboard
- D. Trackpad
Answer: A
Explanation:
A physical bulge under the trackpad is a classic CompTIA-identified symptom of a swollen lithium-ion battery. As batteries degrade, internal gas buildup expands the casing, pushing upward on the laptop chassis-often distorting the trackpad, keyboard, or bottom shell. This can cause cursor issues, clicking problems, and safety hazards.
Replacing the battery first is essential because swollen batteries can rupture, leak, or ignite. Only after the battery is removed and replaced should the technician evaluate whether the trackpad suffered permanent damage.
Replacing the trackpad (D) without addressing the battery fails to correct the root cause. The motherboard (A) and heat sink (B) are unrelated to the physical bulge.
Thus, the correct first step is replacing the battery.
NEW QUESTION # 119

NEW QUESTION # 121
A developer wants to protect critical data from hard drive failure. Their workstation has two hard drives. Which RAID level should they use?
- A. RAID 0
- B. RAID 10
- C. RAID 1
- D. RAID 5
Answer: C
Explanation:
RAID 1 (mirroring) is the only option that provides data protection from hard drive failure using a minimum of two hard drives. In a RAID 1 configuration, an exact copy of the data is simultaneously written to both disks. If one disk fails, the data is still accessible on the remaining drive, ensuring no data loss and continuous operation. This makes it ideal for critical data on a workstation with limited drive capacity.
