220-1101 Practice Test

Explanation: If the user can hear sound through a Bluetooth headset but not through the laptop's internal speakers, the issue is likely related to the laptop's audio settings. One of the most common causes is that the laptop's speakers might be muted, either in the system settings or via a hardware mute button. This is the simplest and most likely solution to the problem.
✑ B. Toggling the laptop's mute setting: Checking whether the laptop is muted, either through the keyboard shortcut or the system sound settings, is a quick way to resolve this common issue.
Why the other options are incorrect:
✑ A. Updating the Bluetooth drivers: The issue is not with the Bluetooth headset, as it is working correctly. The problem is with the laptop's speakers.
✑ C. Updating the speaker drivers: Updating the drivers is not the first step in troubleshooting, as the issue is more likely related to settings rather than outdated drivers.
✑ D. Replacing the laptop's speakers: This is an extreme step and unlikely to be necessary if the problem is simply related to audio settings.
This scenario covers hardware troubleshooting and falls under the Hardware and Software Troubleshooting domain in the CompTIA A+ Core 1 exam.

Explanation: A Storage Area Network (SAN) is primarily used for data archiving and large-scale storage. SANs provide high-speed, block-level storage for enterprise environments.
✑ Why Not A (PAN): Personal Area Networks are for connecting personal devices like phones and smartwatches.
✑ Why Not B (MAN): Metropolitan Area Networks are for city-wide data communication, not storage.
✑ Why Not D (LAN): Local Area Networks are for general connectivity, not dedicated storage.
✑ Why Not WAN: Wide Area Networks are for connecting geographically dispersed networks, not storage.

Explanation: When configuring a network device like a printer, assigning it a static IP address ensures that it always uses the same IP address. If a static IP cannot be set due to security restrictions, the next best solution is to configure a reservation in the DHCP (Dynamic Host Configuration Protocol) server. This reservation ensures that the device (in this case, the printer) always receives the same IP address based on its MAC address, even if the router restarts.
✑ A. Reservation: A DHCP reservation ties a specific IP address to the MAC address of a device, ensuring it always receives the same IP address from the DHCP server. Why the other options are incorrect:
✑ B. Scope: A DHCP scope defines the range of IP addresses that can be assigned to devices. It doesn’t ensure that a specific device always gets the same IP.
✑ C. Lease: A lease refers to the length of time a device is assigned an IP address from the DHCP server. It doesn’t guarantee that the same IP will be re-assigned after the lease expires.
✑ D. Exclusion: An exclusion in DHCP configuration excludes specific IP addresses from being assigned dynamically. This is used to prevent certain addresses from being given out but doesn’t ensure a device will always get the same IP.
This topic is covered under the Networking domain of the CompTIA A+ Core 1 exam.

Explanation: To connect printers without an RJ45 port to the network, the technician needs to enable wireless connectivity. By configuring the printers to connect to the network wirelessly, the company can achieve the desired consistency in printer configuration across the office. This approach allows printers without built-in wired network capabilities to be part of the network, facilitating shared access and remote printing functionalities. References:
