Free Practice Questions for CompTIA 220-1201 Exam

The first security step after deploying a new router is to change the default administrative password. Default credentials are well known and pose a security risk if left unchanged.

From CompTIA A+ 220-1101 Official Study Guide, Objective 2.3 – Secure a wireless network:

“Always change default administrative credentials before further configuration to prevent unauthorized access.”

Reasoning: Projectors have air filters that prevent dust from entering the internal components. A clogged filter can cause the projector to overheat, resulting in shutdowns and even strange smells due to overheating components. Cleaning the filter is a standard troubleshooting step when projectors exhibit overheating symptoms.

Why the Other Options Are Incorrect:

A. Replace the bulb:

While a failing bulb may eventually cause issues, it would not typically result in a strange smell or repeated shutdowns after a fixed period. Bulb issues usually manifest as dim or flickering images.

B. Check the projector configuration:

Configuration settings, such as resolution or input options, would not cause overheating or shutdowns. This option does not address the described symptoms.

D. Adjust the gamma settings:

Gamma settings affect display brightness and contrast but have no impact on overheating or strange smells.

Practical Example:

Dust accumulation in projectors is a common issue, especially in environments with poor air circulation. A clogged filter causes restricted airflow, leading to overheating and automatic shutdowns to protect internal components. Cleaning the filter typically resolves this issue.

CompTIA A+ Exam Objective Alignment:

Objective 5.5: Troubleshoot common video, projector, and display issues.

A distorted image where the screen is not symmetrical (wider at the top or bottom) is typically due to keystone distortion. Adjusting the projector's keystone settings corrects this trapezoidal effect caused by an angled projection.

A firewall implements ACLs (Access Control Lists) to filter traffic and enforce policies based on rules such as IP address, port, or protocol.

Why Not A (Managed switch): A managed switch supports VLANs and QoS but does not enforce ACLs at the network perimeter.

Why Not B (Gateway): Gateways connect networks and translate protocols but don’t typically implement ACLs.

Why Not C (Repeater): Repeaters extend signal range but don’t enforce policies.

Fiber optic connections provide the highest data transfer rates and symmetrical upload and download speeds. This makes fiber the ideal choice for applications requiring high-speed connectivity, such as video conferencing, large file transfers, and cloud-based workflows.

Bluetooth is a wireless technology designed for short-range communication between devices. It is a classic example of a Personal Area Network (PAN), which supports communication between devices like smartphones, headsets, keyboards, and mice within a few meters. PANs are smaller in scope compared to LANs or WANs.

Improper seating is the most common reason an SSD isn’t recognized. Ensuring it is correctly connected resolves the issue.

Why Not A (Faulty SSD): A faulty SSD is possible but less likely than an installation issue.

Why Not B (Not formatted): Formatting affects data usability, not drive detection.

Why Not C (Incompatibility): SSD compatibility issues are rare with modern hardware.
