220-1201 Exam Dumps - CompTIA A+ Questions and Answers

correct answer is " Overclocking " and " Reduce CPU Clock speed " CPU is at 4.5 Ghz when normal is 3.2 Ghz. Overclocking too much can cause freezes, and this is a gaming computer sothe user probably took it too far. http://blog.logicalincrements.com/2018/12/4-troubleshooting-tips-overclocking-pc/

The best answer provided is A , although it is important to note that the question is somewhat misleading because it asks about motherboard selection but provides mostly incorrect or irrelevant motherboard-related options.

For high-performance workloads such as video editing and virtual reality (VR) using an Intel Core i9 processor and multiple graphics cards (multi-GPU setup) , system design considerations include high power consumption and significant heat output. In the CompTIA A+ Core 1 220-1201 objectives under hardware planning and troubleshooting, high-performance CPUs and multiple GPUs require adequate thermal management solutions , including advanced cooling systems (air or liquid cooling) to ensure system stability and prevent thermal throttling.

Why A is the best answer:

High-end CPUs like Intel Core i9 and multiple GPUs generate substantial heat.

Proper cooling is essential for maintaining performance under sustained load (video rendering, VR workloads).

While not strictly a motherboard feature, cooling is a critical system requirement for such a build.

Why the other options are incorrect:

B. Use DDR3 RAM for increased compatibility

Incorrect because modern Intel Core i9 platforms use DDR4 or DDR5 , not DDR3, which is obsolete and incompatible with current high-performance motherboards.

C. Verify there are two PCIe x1 slots for additional devices

Incorrect because PCIe x1 slots are used for low-bandwidth devices (sound cards, network cards), not graphics cards.

Multiple GPUs require PCIe x16 slots , not x1.

D. Select a motherboard with integrated graphics to support video output

Incorrect because high-performance systems with discrete GPUs rely on those GPUs for rendering. Integrated graphics are unnecessary and sometimes disabled when a dedicated GPU is installed.

Exam Insight (CompTIA A+ perspective):

In real-world A+ Core 1 scenarios, the correct motherboard selection for this requirement would focus on:

Multiple PCIe x16 slots (for multi-GPU support)

Compatible socket for Intel Core i9

Support for modern RAM (DDR4/DDR5)

Adequate chipset and power delivery (VRM design)

Proper cooling solution for thermal management

However, since those correct motherboard specifications are not provided in the options, A is the only viable system-level requirement relevant to stability under high-performance load .

The correct answer is D. SMTP (Simple Mail Transfer Protocol) .

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

SMTP is the standard protocol used to send emails from a client to a mail server or between servers.

POP3 (Post Office Protocol 3) and IMAP (Internet Message Access Protocol) are used for receiving emails , not sending them.

LDAP (Lightweight Directory Access Protocol) is used for accessing and managing directory services, such as authentication and organizational information, not for email transport.

Scan-to-email functions rely on the printer sending scanned documents to an email server. CompTIA A+ identifies SMTP (Simple Mail Transfer Protocol) as the protocol responsible for sending email messages from clients to mail servers. When configuring scan-to-email, the technician must enter:

SMTP server address

Authentication credentials

Port number (25, 465, or 587)

Encryption type (TLS/SSL)

Without SMTP, the printer cannot transmit emails.

SMS (A) refers to text messaging. SFTP (C) is secure file transfer, common for scan-to-folder workflows, not email. SMB (D) is used for Windows file sharing.

Therefore, the correct protocol is SMTP.

Intermittent freezing followed by unexpected restarts after the system has been running for a while often points to a hardware stability problem that worsens with heat and time, rather than an immediate configuration or “not enough resources” issue. When diagnostics show no errors, the next CompTIA A+-style step is to look for physical signs of failing components. Swollen or leaking capacitors on the motherboard or in the power delivery area can cause unstable voltage regulation as the system warms up, leading to input lag, lockups, and spontaneous reboots even during light tasks like reading email. A visual inspection can quickly confirm this failure mode and is an appropriate next troubleshooting action when software and basic diagnostics are inconclusive.

Replacing the power supply with a higher wattage is not the best next step because the workload described is not high draw, and the symptom is not clearly tied to peak load; if a PSU is suspect, the usual step is testing with a known-good PSU of correct specs, not simply “higher wattage.” Increasing RAM is unnecessary because the system meets requirements and this would more commonly cause persistent slowness, not sudden restarts. A CMOS battery issue typically causes time resets or BIOS setting loss, not freezing and random reboots after hours.

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.

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

A cable modem connects to an ISP’s wall jack using a coaxial cable, and the standard connector used for coaxial connections is the F-type connector. According to CompTIA Core 1 (220-1201) networking hardware and cabling objectives, F-type connectors are specifically designed for coaxial cabling used in cable television and cable internet (DOCSIS) installations. These connectors screw onto the coaxial wall outlet and the cable modem, ensuring a secure physical connection and proper signal transmission.

An LC connector is a fiber-optic connector commonly used with single-mode or multimode fiber cables and is not associated with cable modems. An RJ45 connector is used for Ethernet networking and is typically used to connect the cable modem to a router or computer, not to the wall jack. Lightning is a proprietary Apple connector used for charging and data transfer on mobile devices and has no role in network uplinks.

CompTIA expects candidates to clearly distinguish between different cable types and connectors based on the service being installed. When the scenario involves a cable modem and ISP wall jack, the correct and standard connector is the F-type.

The correct answer is A. Virtual LAN (VLAN) .

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

VLANs are used to segment a physical network into multiple logical networks. By assigning the accounting department to a separate VLAN, users on other VLANs cannot access its network traffic without routing, thereby isolating sensitive departments while using the same physical switch.

VLANs improve security, reduce broadcast traffic, and allow network administrators to enforce access controls at the layer 2 level.

Why the other options are incorrect:

B. DHCP reservations: Ensure that specific devices always receive the same IP address, but do not restrict network access.

C. Content filtering: Controls web or application traffic based on content, not segmenting network access between departments.

D. Port security: Limits which devices can connect to a port but does not provide full network segmentation for an entire department.
