Q123. A user reports the following:
1. When accessing large images, PC performance is degraded.
2. When accessing small text files, PC performance is as expected.
Which of the following is the most likely cause of the performance issues?

HDD fragmentation

RAID controller failure

RAID array configuration errors

Insufficient power supply

The issue described indicates that performance degradation occurs specifically when accessing large images, while small text files do not cause the same problem. This suggests a problem related to handling large files or data throughput.
HDD fragmentation is a common issue that can cause performance problems with large files, as fragmented files take longer to read and write. This issue would not typically affect the performance of small text files in the same way.

Q124. A company has implemented a policy that allows employees to use personal devices to perform work duties. Which of the following policies should the technician activate to protect company information?

MFD

MAM

MFA

MDM

Mobile Device Management (MDM) policies are crucial for companies that allow employees to use personal devices for work duties. MDM enables the company to enforce security policies, manage and secure corporate data on personal devices, and ensure compliance with company standards. It allows for remote management of these devices, including the ability to remotely wipe company data if the device is lost or stolen, without impacting personal data, thereby protecting company information effectively.

Q125. A help desk technician plugged in a user’s new computer to a network port. After a few minutes, the computer showed an APIPA address. Which of the following is the MOST likely reason this happened?

The WLAN is disabling the NIC card.

The network cable is not attached.

The PC is unable to contact a DHCP server.

The DHCP server is using addresses in the range of 169.254.254.1.

The most likely reason for a computer showing an APIPA address after being plugged into a network port is that the PC is unable to contact a DHCP server1. Automatic Private IP Addressing (APIPA) is a DHCP fail-safe that protects a computer system from failure. It invokes a standby mechanism for local Internet Protocol version 4 (IPv4) networks supported by Microsoft Windows.
With APIPA, DHCP clients can obtain IP addresses even when DHCP servers are not functional.

Q126. A technician is tasked with upgrading a laptop’s RAM. Which of the following steps should the technician lake FIRST?

Q130. Some users are unable to access resources on the file server. A technician reviews the server network information and finds the following settings:

Which of the following is the most likely explanation?

Applicable ports have been closed during routine hardening.

Server gateway settings are incorrect.

The server lost power during a recent storm and did not resume operation.

The route was removed from the border router.

Given the network information for the server “InternalToolCentral” with an IP address of
“192.130.230.5” and a subnet mask of “255.255.255.0”, the gateway address should be within the same network range. However, the gateway address is listed as “192.130.230.1”, which is correct and within the same subnet. Therefore, the issue is not with the gateway settings. The DNS servers are listed as “8.8.8.8” and “4.2.2.1”, which are public DNS servers and should be able to resolve domain names correctly if they are reachable. The open ports listed include 25 (SMTP), 80 (HTTP), 110 (POP3), 443 (HTTPS), and 3306 (MySQL), which are standard ports for their respective services. Considering the provided options and the network settings, the most likely explanation for users being unable to access resources on the file server is: A. Applicable ports have been closed during routine hardening. This could prevent users from connecting to the necessary services on the file server.

Q131. A user connects a laptop to a conference room audiovisual system using a VGA cable. The TV displays the image correctly, but the audio is not working. Which of the following will most likely resolve the issue?

Replacing the VGA cable

Switching inputs

Using HDMI to connect

Restarting the audiovisual system

VGA (Video Graphics Array) cables transmit analog video signals only and do not carry audio signals. When a user connects a laptop to an audiovisual system using a VGA cable, the lack of audio is due to VGA’s inability to transmit sound. Switching to an HDMI (High-Definition Multimedia Interface) cable, which supports both audio and video signals, will most likely resolve the issue by enabling the transmission of sound to the audiovisual system alongside the video.

A hybrid cloud is a cloud computing environment that combines on-premises, private cloud, and public cloud resources. This configuration allows organizations to deploy workloads and data in a way that optimizes performance, security, and cost management.
* Key Characteristics of a Hybrid Cloud:
* Combines private cloud (on-premises or dedicated servers) and public cloud (resources accessed over the internet).
* Allows for the movement of data and applications between private and public clouds.
* Supports scenarios where certain data must remain on-premises for security or compliance reasons, while other workloads utilize the scalability of public cloud resources.
Comparison to Other Options:
* A. Private Cloud: A private cloud is a dedicated environment for a single organization, either on- premises or hosted by a service provider. It does not include any public cloud integration, as seen in a hybrid model.
* C. Community Cloud: This model is shared among several organizations with similar requirements, typically for collaborative projects, and does not blend public and private infrastructure.
* D. Public Cloud: Resources are entirely hosted on a cloud provider’s infrastructure and are shared among multiple customers, lacking the private, dedicated resources of a hybrid setup.
CompTIA A+ Exam Objectives References:
* 220-1101 (Core 1), Section 4.1 outlines various cloud-computing models, including private, public, hybrid, and community clouds.
* Hybrid cloud is explicitly described as an environment that mixes private and public resources to deliver flexible and scalable solutions.
