정답:
Explanation:
Infrastructure as a Service (IaaS) provides virtualized computing resources over the internet such as servers, storage, and networking. It allows a business to quickly spin up virtual machines and is ideal for disaster recovery and scalable IT infrastructure needs.
Option B: SecaaS focuses on cloud-delivered security, not infrastructure.
Option C: PaaS offers development environments, not full virtual infrastructure.
Option D: SaaS delivers applications over the internet (e.g., email, CRM) not for disaster recovery.

정답:
Explanation:
A DHCP reservation binds a specific MAC address to an IP address so the device always receives the same IP from the DHCP server. This ensures network devices like printers maintain consistent connectivity and availability even when the IP pool is low.

정답:
Explanation:
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.

Explanation:
Near-field communication (NFC) is a short-distance wireless communication method widely used in mobile payment systems like Apple Pay and Google Pay. Simply placing the device near a compatible terminal initiates the payment process.

정답:
Explanation:
After determining the issue is likely on the remote server, the technician should test the theory to confirm the root cause before proceeding.
Why Not A (Document the findings): Documentation comes after confirming the issue.
Why Not C (Gather information): Information gathering is already completed.
Why Not D (Establish a plan of action): This is done after confirming the issue.

Explanation:
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.

정답:
Explanation:
The most likely cause is third-party or ill-fitting cases obstructing the contact between the stylus and the tablet charging mechanism. Some cases may not be designed with stylus charging in mind, particularly if users are purchasing their own accessories.
Option B: A software update might fix OS-related issues, but would not typically affect physical charging.
Option C: If some devices had defects, the issue would likely be consistent, not isolated to some users.
Option D: Firmware issues could be a factor but are less likely than physical obstructions when users are using different accessories.

정답:
Explanation:
RG11 coaxial cable with quad shielding is designed to handle large volumes of internet traffic, providing excellent resistance to interference and high bandwidth capacity.
Why Not A (USB 3.1): USB 3.1 is used for connecting peripherals, not for high-volume internet traffic.
Why Not C (SATA3.0): SATA is used for internal data storage connections, not for network traffic.
Why Not D (Unshielded plenum RJ45): While RJ45 cables are commonly used, unshielded cables are prone to interference and are not ideal for high-volume traffic.

정답:
Explanation:
To allow multiple users to print to networked printers:
Printer shares enable users to access printers shared on the network.
Print servers manage print jobs and provide centralized control of printing.
Why Not B (DHCP server): DHCP is unrelated to print management.
Why Not D (Printer subnet): Subnets group devices but don’t manage printing.
Why Not E (SMB configuration): SMB is for file sharing, not specifically print management.
Why Not F (Printer Wi-Fi settings): These settings are irrelevant since the printers use Ethernet.

Comprehensive and Detailed Step-by-Step
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.

정답:
Explanation:
The appropriate network type for this scenario is a Local Area Network (LAN), which is designed for small, localized networks, such as within a single building or room. LANs are ideal for gaming because they provide high-speed, low-latency connections.
Option A (SAN): Incorrect. A Storage Area Network is used for data storage, not for gaming or general networking.
Option B (MAN): Incorrect. A Metropolitan Area Network covers a city or campus, far exceeding the scope needed for a gaming setup in a single room.
Option D (PAN): Incorrect. A Personal Area Network is designed for a single user, such as Bluetooth devices, and would not support multiple devices connecting to a game server.

정답:
Explanation:
A hybrid cloud combines on-premises infrastructure with public cloud services. One significant advantage is that it allows organizations to keep sensitive data in a private environment to meet regulatory or data residency requirements, while still utilizing the scalability and cost-efficiency of the public cloud for other workloads. This ensures compliance with legal mandates about data location.

정답:
Explanation:
If the system reports “Bootable device not found”, and the BIOS is configured correctly, the next step is to run diagnostics on the hard drive to check for physical or logical failure. It could be a sign of a failing drive or corrupt boot sector.
Option A: Reformatting the drive would erase data not a diagnostic step.
Option C: RAM does not affect whether a drive is bootable.
Option D: Replacing the drive should only be done after diagnostics confirm failure.
