CompTIA Updated 220-1201 Exam Questions and Answers by evangeline

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.

In a corporate office environment where multiple employees must share a single printer, the most efficient and manageable solution is a print server. A print server centralizes print management, queues print jobs, handles driver distribution, and provides access control. CompTIA A+ highlights print servers as the enterprise-standard method for managing shared printing resources because they ensure reliability, scalability, and better network performance.

Bluetooth printing and Wi-Fi Direct are short-range, peer-to-peer technologies meant for one-to-one or small-scale printing. They lack user authentication management, enterprise security controls, and cannot efficiently support dozens or hundreds of print requests simultaneously. Cloud printing requires internet reliance and external service routing, which introduces latency, potential downtime, and privacy concerns—often unsuitable for corporate networks, especially those with sensitive internal documents.

A print server allows users to connect to the printer through a standard network infrastructure (wired or wireless), and technicians can configure permissions, monitor print loads, and troubleshoot from a central location. It integrates seamlessly with enterprise directory services such as Active Directory, enabling controlled access and auditing. Because of these capabilities, the print server is the best professional-grade solution for corporate-wide printing needs.

Comprehensive and Detailed Step-by-Step Explanation:

Random BSODs (Blue Screen of Death), intermittent freezing, and degraded performance under load are common symptoms of failing or faulty RAM (Random Access Memory). Here's the reasoning:

RAM Module (Correct Answer):

Faulty or failing RAM can cause random BSODs due to memory errors when the system attempts to read or write to corrupted memory locations.

Intermittent freezing, especially under performance-intensive operations, can occur because the CPU relies heavily on RAM for active processing tasks.

Over time, heat generated during usage can exacerbate RAM instability, leading to progressively worse performance throughout the day.

Solution: The technician should run a memory diagnostic tool, such as Windows Memory Diagnostic or MemTest86, to confirm if the RAM is at fault.

Incorrect Options:

A. Video Card: A faulty video card can cause graphical glitches, screen artifacts, or crashes, but it is unlikely to cause system-wide performance degradation and random freezing under normal operations unless the issue is specific to GPU-intensive tasks (e.g., gaming or video rendering).

B. HDD: A failing hard drive can cause system slowdowns and freezing, but it typically produces other symptoms such as read/write errors, boot failures, or clicking sounds. HDD issues do not usually cause BSODs unless critical system files are corrupted.

D. TPM (Trusted Platform Module): A TPM is a hardware-based security module used for encryption and secure authentication. It does not affect performance or cause BSODs or freezing under normal operation.

Key Takeaway:

The symptoms described (random BSODs, intermittent freezing, and degraded performance under load) are most likely caused by faulty or failing RAM. Memory diagnostic tools should be used to confirm the issue.

Cable modems supplied by ISPs connect to the coaxial wall outlet using an F-type connector. CompTIA A+ specifies that F-type connectors are threaded coaxial connectors used in broadband cable internet, cable TV, and some satellite systems. They attach to RG-6 or RG-59 coaxial cable and provide a secure, shielded connection to the cable provider’s infrastructure.

The cable modem requires this coaxial uplink to receive downstream and upstream signals from the ISP before converting them into Ethernet on the LAN side.

LC (B) is for fiber optic connectors, not coaxial. RJ45 (C) is an Ethernet connector and is used on the LAN side of the modem—not on the wall uplink. Lightning (D) is an Apple connector and irrelevant to networking hardware.

Thus, the correct connector for the ISP cable modem uplink is F-type.
