The company should buy Coaxial cables to be used with F-type connectors.

If a user is unable to connect a laptop to a projector or videoconferencing system and sees the error message "No source found," the next step should be to check the display settings on the computer and set them to extend/duplicate. This will ensure that the laptop's display is being output to the external device. References: CompTIA A+ Certification Exam Guide, pg. 514

HDMI-ARC (Audio Return Channel) is an HDMI connection that allows audio to be sent from the TV to an external sound system, such as a soundbar. If the TV's HDMI-ARC port is not being used, then the soundbar will not receive any audio from the TV and thus will not produce any sound. To resolve the issue, the technician should ensure that the TV's HDMI-ARC port is being used to connect the TV to the soundbar.

A managed switch provides advanced features such as traffic monitoring and VLAN configuration, allowing a technician to view network statistics for devices on the local subnet.

Why Not B (Router): A router connects different networks and directs traffic between them but does not provide detailed subnet-level statistics.

Why Not C (Access point): Access points provide wireless connectivity but lack traffic monitoring features.

Why Not D (Firewall): A firewall filters traffic but is not used for monitoring detailed statistics on a local subnet.

In the SaaS (Software as a Service) model, the service provider manages the infrastructure, platforms, and software applications, including maintenance tasks such as application patching. Users access the applications over the internet, and the provider is responsible for ensuring the software is up to date, secure, and performing optimally. This model contrasts with IaaS (Infrastructure as a Service) and PaaS (Platform as a Service), where the customer has more control and responsibility over the environment and may need to manage patching for applications they develop or install.

nces: SaaS is designed to relieve users from the complexity of software maintenance, including patch management, as highlighted in cloud computing service model descriptions.

When a new drive is not recognized by Windows 10, and it's known that the drive was formatted before going offline, checking the file system format is crucial. Windows does not natively recognize the ext4 file system, commonly used in Linux environments. If the drive was inadvertently formatted to ext4, Windows would not display or allow access to it. The solution involves reformatting the drive to a file system that Windows recognizes, such as NTFS or FAT32, ensuring the drive becomes visible and accessible within Windows 10.

A common reason for a POST failure after a motherboard installation is improperly seated RAM. The system requires working memory to successfully complete POST. Reseating (removing and reinserting) the RAM ensures it's making proper contact with the motherboard.

Option A: Flashing the BIOS is not possible if the system won’t POST.

Option B: A dead CMOS battery can cause BIOS settings to reset, but it usually won’t prevent POST entirely.

Option D: Reinstalling the old motherboard is premature — basic troubleshooting steps should be completed first.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 3.5: Given a scenario, troubleshoot problems related to motherboards, RAM, CPU, and power.

Satellite internet is most commonly used in remote areas where wired infrastructure (e.g., fiber or cable) is unavailable. It relies on satellite communication, making it suitable for isolated locations.

Why Not A (Fiber): Fiber requires physical infrastructure, which is rarely available in remote areas.

Why Not B (Cable): Cable internet relies on coaxial infrastructure, which is often unavailable in remote locations.

Why Not D (DSL): DSL depends on existing telephone lines, which may not reach remote areas.

Why Not E (Cellular): Cellular can work in remote areas, but satellite is often the only option for extremely isolated locations.
