220-1101 Exam Dumps - CompTIA A+ Certification Exam: Core 1

The Syslog server collects logs and system messages from devices on a network. It’s a standard protocol used to store log messages from network hardware like routers, switches, and servers for diagnostics and auditing.

Option A (DNS): Translates domain names into IP addresses, not used for logging.

Option B (Mail): Manages email communication.

Option C (Print): Manages print jobs and printer sharing.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 2.4: Compare and contrast common networking hardware.

Comprehensive and Detailed Step-by-Step Explanation:

To answer this question, we need to identify the port numbers associated with email protocols used in client-server communication.

Port 25 (SMTP - Simple Mail Transfer Protocol):

This port is primarily used for sending emails between mail servers and from mail clients to mail servers (sending outbound mail).

SMTP is an essential protocol for email traffic.

The primary security concern with virtual machine escape is compromising the hypervisor, which can allow attackers to gain access to other virtual machines or the host system. Virtual machine escape refers to an attack that allows a guest virtual machine to break out of its isolated environment and access other parts of the system.

Mobile Application Management (MAM) enforces policies restricting access to apps and services based on location, ensuring security at external sites.

Why Not A (MOW): "Mobile Only Workplace" (MOW) is not a recognized term in this context.

Why Not B (MAN): Metropolitan Area Network (MAN) is unrelated to mobile device policies.

Why Not C (MFA): Multi-Factor Authentication secures user accounts but does not enforce app restrictions.

CompTIA A+ Exam Reference: Core 2 (220-1102), Section 2.7, mobile device security policies​.

Comprehensive and Detailed In-Depth Explanation:

To change a domain password from a remote location, the system must communicate with the domain controller. Since the user is working from home, they need to connect to the corporate VPN to establish that secure connection. Without it, the password change cannot be authenticated.

Option A: Restarting will not resolve the lack of connection to the domain controller.

Option C: Resetting the password in AD could help, but doesn’t let the user reset it themselves.

Option D: The user may already be on Wi-Fi; the issue is with connecting to the corporate network, not local.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 1.6: Given a scenario, configure basic mobile device network connectivity and application support.

===========

The issue described suggests the 12V CPU power connector was likely forgotten during installation. The 12V power rail is essential for the operation of high-end workstation components, including the CPU. Without the 12V connection, the system will fail to POST and may power off shortly after being turned on.

Why 12V?

The 12V connector is critical for providing power to the CPU via the motherboard. Modern CPUs require a dedicated power source from the PSU, usually supplied through the 4-pin or 8-pin EPS12V connector.

If this connection is omitted, the motherboard will not receive adequate power for the CPU to function, resulting in the system failing to POST or shutting down after a brief period.

Incorrect Options:

A. 5V: The 5V rail powers USB devices, some motherboard components, and certain peripherals, but not the CPU directly.

C. 120V and D. 220V: These voltages refer to the power supply’s input from the wall outlet, not the internal connections to components.
