The correct answer is B. Header pinouts.

According to CompTIA A+ Core 1 220-1201 objectives under Hardware:

Header pinouts on a motherboard are designated connectors for internal components such as USB ports, audio connectors, and front panel buttons/LEDs.

When adding additional internal USB ports, a technician typically connects them to the motherboard’s USB header pinouts. These headers provide the necessary data and power connections to enable USB functionality for front-panel or expansion USB ports.

Why the other options are incorrect:

A. TPM (Trusted Platform Module): Used for hardware-based security functions like encryption, not USB connectivity.

C. M.2 connector: Used primarily for SSDs and other small-form-factor expansion devices, not standard USB ports.

D. Expansion slots: Typically PCIe or PCI slots are used for expansion cards such as GPUs, network cards, or USB controller cards, but not for connecting internal USB headers directly.

A spam gateway is an email-security system positioned in the mail-delivery path. It examines incoming messages and attempts to identify spam, phishing messages, malicious attachments, suspicious links, spoofed senders, and other unwanted content.

Depending on its configuration, a spam gateway can:

Reject the message.

Quarantine it for review.

Mark it as spam.

Deliver it to a junk-mail folder.

Remove or block malicious content.

Because the question specifically asks about preventing unwanted email from reaching an inbox, a spam gateway is the most precise answer.

A proxy server commonly intermediates web or application requests.

An intrusion detection system monitors activity and generates alerts but does not primarily filter email.

A firewall filters network connections and ports but normally does not perform detailed email-content classification.

CompTIA objective 2.3 explicitly identifies spam gateways as network-based internet appliances. Microsoft’s anti-spam documentation explains that spam filtering identifies and separates unwanted email from legitimate messages

An MX, or Mail Exchanger, record is a type of DNS resource record. It identifies the mail server responsible for accepting email for a particular domain. Consequently, an MX record is created or modified in the domain’s DNS zone , which is hosted on a DNS server.

Although the MX record points to a mail server, the record itself is configured through DNS. The mail server is the destination identified by the record, not the service in which the DNS record is stored.

A proxy server intermediates network requests, commonly for filtering, caching, or privacy.

A mail server sends, receives, and stores email, but DNS tells other systems how to locate it.

A print server manages printers and print jobs.

CompTIA objective 2.4 specifically includes DNS record types such as A, AAAA, CNAME, MX, and TXT. Microsoft also defines an MX record as a DNS resource record that identifies a domain’s mail server.

==========

For a main database server with high read/write activity, the best RAID choice must deliver strong performance while still providing fault tolerance. Per CompTIA A+ Core 1 (220-1201) storage/RAID objectives, RAID 10 (1+0) combines disk mirroring (RAID 1) and disk striping (RAID 0). Striping improves performance by distributing read/write operations across multiple disks, which is ideal for databases that perform frequent transactions. Mirroring provides redundancy by keeping an identical copy of data on a paired drive, allowing the system to tolerate drive failures (typically one drive per mirrored pair) without data loss.

RAID 0 is fast but offers no redundancy, making it inappropriate for critical servers. RAID 5 and RAID 6 use parity, which provides redundancy but introduces a write penalty because parity must be calculated and written during updates—often a poor fit for workloads with heavy random writes like databases. RAID 6 is even more write-intensive

The correct answer is A. Clean the feed rollers.

According to CompTIA A+ Core 1 220-1201 objectives under Printers:

Frequent paper jams, particularly in high-use shared printers, are commonly caused by dirty or worn feed rollers.

Cleaning the feed rollers removes dust, paper debris, and toner residue that can prevent smooth paper feeding, especially when printing double-sided documents.

This is a standard preventive maintenance procedure that improves reliability and extends the printer’s operational life.

Why the other options are incorrect:

B. Use a different paper weight: A4 standard paper is appropriate; changing paper weight is unnecessary unless the paper is damaged or incompatible.

C. Replace the fuser unit: Fuser problems generally cause smudging or incomplete fusing, not frequent paper jams.

D. Change the toner cartridge: Toner issues affect print quality (light or streaky prints), not paper feeding or jamming.

The correct answer is A. Duplex.

In the CompTIA A+ Core 1 (220-1201) exam objectives under printer settings and configuration, duplex printing refers to printing on both sides of the paper automatically.

Using duplex printing is the best way to reduce resource consumption because:

It cuts paper usage in half, which is the primary resource being conserved.

It is ideal for multi-page documents and multiple copies.

It reduces physical storage and handling requirements.

Why the other options are incorrect:

B. Orientation

Orientation (portrait or landscape) changes the layout of the document but does not reduce resource usage.

C. Tray settings

Tray settings determine which paper tray is used (e.g., plain paper, letterhead), but they do not impact resource consumption.

D. Quality

Print quality (draft, normal, high) may affect ink/toner usage, but it does not reduce paper consumption as effectively as duplex printing, which is the main resource concern in this scenario.

Final Answer: A. Duplex

The correct answer is A. RJ11.

According to CompTIA A+ Core 1 220-1201 objectives under Networking:

RJ11 connectors are commonly used for telephone lines and data cables that use two pairs of wires (four wires total).

This connector is standard for analog telephone connections and DSL connections.

Why the other options are incorrect:

B. F-type: Used for coaxial cables, commonly in cable TV or broadband internet, not for two-pair data cables.

C. ST: A type of fiber optic connector, not used for copper two-pair wiring.

D. Molex: Primarily used for power connections in computer hardware, not for network or phone cabling.

The correct answer is B. Secure Boot.

According to CompTIA A+ Core 1 220-1201 objectives under Security:

Secure Boot is a UEFI firmware feature that ensures a computer boots only with software that is trusted and digitally signed by the manufacturer.

This prevents malicious or unauthorized bootloaders and operating systems from loading, protecting the system from rootkits and other boot-time attacks.

Secure Boot does not require disabling USB devices; it simply checks that any bootable device contains a signed operating system.

Why the other options are incorrect:

A. BIOS password: Protects access to BIOS/UEFI settings but does not verify trusted software during boot.

C. USB settings: Can control USB access but cannot enforce boot validation for signed OS or prevent unauthorized boot devices.

D. Single sign-on: Provides authentication convenience for users, unrelated to boot security.

Because the smudges are not in the original document, CompTIA A+ troubleshooting logic indicates the problem is occurring inside the print process, not in the application or file. For laser printers, smudging commonly points to an issue with the imaging components—especially the drum/photoconductor unit (and sometimes the fuser). A+ Core 1 (220-1201) printer troubleshooting emphasizes starting with the most likely, easiest-to-verify causes before replacing parts. Inspecting the drum is a diagnostic step that can reveal visible defects such as scratches, toner buildup, contamination, or worn surfaces that cause toner to transfer incorrectly, leading to streaks or smears on output.

Replacing the toner (D) is a corrective action and may be unnecessary if the drum is damaged. Changing paper type (A) can help with some issues (like poor fusing or humidity-related problems), but it’s less directly tied to consistent smudges caused by the imaging process. Firmware updates (C) are rarely the first step for print-quality defects; they’re more relevant to compatibility, bugs, or feature issues—not physical smearing. Therefore, inspecting the printer drum first best matches A+ methodology and common laser printer failure points.

The correct answer is D. Check for loose connections on the display.

According to CompTIA A+ Core 1 220-1201 objectives under Hardware and Display Troubleshooting:

Flickering or strange colored lines on a monitor are often caused by loose or damaged video cable connections (internal or external).

Before considering costly or time-consuming solutions like replacement, the technician should verify that the display cable, internal ribbon cables, or connectors are properly seated.

Why the other options are incorrect:

A. Suggest a secondary monitor: Provides a temporary workaround but does not resolve the underlying hardware issue.

B. Conduct a factory reset: Resets software settings but will not correct physical connection problems that cause flickering or colored lines.

C. Install a screen protector: Does not affect video signal or display functionality; irrelevant for flickering issues.
