Explanation:
A sandbox in virtualization allows testing an application in an isolated environment to observe its behavior without affecting the host system.
Why Not A (Run an application on multiple workstations): This describes application virtualization, not sandboxing.
Why Not C (Migrate a legacy application): This is about virtualization for legacy support, not testing.
Why Not D (Create a firewall): A firewall does not act as a sandbox for application testing.

Explanation:
Unmanaged switches require no configuration―they simply need to be plugged in and start working immediately, making them ideal for simple network setups.
Managed switches provide advanced features such as VLANs, SNMP monitoring, port security, and traffic management, but require configuration.
From CompTIA A+ 220-1101 Official Study Guide, Objective 2.2 C Compare and contrast common networking hardware:
“Unmanaged switches operate out of the box with no configuration and are designed for simple
connectivity. Managed switches allow for configuration, monitoring, and management of network
traffic and security.”

Explanation:
If only one print job fails and others succeed, it is often due to a paper type or tray selection mismatch for that specific job. If a print job is configured to use a tray that is empty or set to manual feed, it will not be released until resolved.
From CompTIA A+ 220-1101 Official Study Guide, Objective 4.3 C Printer troubleshooting:
“If a specific print job stalls while others succeed, check the job settings for specific tray or paper type configurations that do not match the printer’s current setup.”

Explanation:
An eSIM (embedded SIM) allows users to change carriers and provision new cellular service without installing any physical hardware. It is managed via software and is ideal for international travelers who need to switch providers quickly.
From the CompTIA A+ 220-1101 Official Study Guide, Objective 3.3 C Install and configure mobile device network connectivity:
"eSIMs provide carrier flexibility by enabling remote provisioning and profile switching, making it possible to connect to different networks without a physical SIM card."

Explanation:
Dual-BIOS motherboards contain two firmware chips. If the primary BIOS becomes corrupted, the system can failover to the secondary BIOS. Most boards allow manual enabling of the secondary BIOS via a physical switch or jumper.
Option B: Downgrading firmware may not be possible if the system won’t POST or access UEFI.
Option C: Not necessary until both BIOS chips are non-functional.
Option D: Thermal paste affects heat dissipation, not BIOS/boot behavior.
