NEW QUESTION # 208
A user is attempting to run a high-end graphics application on a computer with integrated video, but the application fails to start, reporting that the system does not meet the minimum video RAM requirements. The computer has 16 GB of system RAM installed. Which of the following should the technician adjust to resolve this issue?
Answer: C
Explanation:
With integrated graphics, "VRAM" is often not dedicated memory on a discrete card-graphics may instead borrow system RAM . Quentin Docter explains this directly: if the video card is built into the motherboard, it
"likely won't have its own memory but will share system memory," meaning the total system RAM is split between the OS and video usage. Docter then answers the key "where do I change this?" question: " Shared memory is configured in the system BIOS/UEFI ," and some BIOS/UEFI setups allow you to set aside a specific amount (example given: 512 MB) for video memory.
That is exactly why the machine can have plenty of DRAM yet fail a VRAM check: the BIOS/UEFI allocation for integrated graphics may be set too low. Adjusting BIOS/UEFI settings to reserve more memory for the integrated GPU is the most direct way to attempt meeting a VRAM requirement (when supported).
Device Manager and System Configuration won't change reserved video memory allocation, and "Virtual RAM" (paging) is unrelated to VRAM. Therefore, BIOS options is correct.
NEW QUESTION # 209
An IT manager is planning to deploy a critical security update for a custom business application to all workstations in the organization. To ensure the update does not cause system instability or compatibility issues with existing software, which of the following should the technician perform FIRST?
Answer: B
Explanation:
Before deploying an application update broadly, best practice is to test it in an isolated environment to avoid breaking production systems. The All-in-One guide defines sandbox testing clearly: "a sandbox is a place where you can experiment without messing up the primary system," typically a virtualized environment, and it "entails checking out new and updated applications without putting the systems and data you depend on at risk." That directly aligns with rolling out a new application update across the organization.
Mike Meyers' Lab Manual repeats the same concept: sandbox testing uses an isolated environment and snapshots to test changes safely before production deployment. It's positioned as a documented business process within change-management best practices, reinforcing why it comes early-before impact spreads.
A backup/rollback plan is important too, but the question asks for the first step when applying a new update to everyone. Testing first helps identify compatibility issues, installation failures, and side effects early-so you don't deploy a bad update at scale. Therefore, Sandbox testing (C) is correct.
NEW QUESTION # 210
A technician needs to delete an application's local data from a specific user account, but when the technician navigates to the C:\Users\EmployeeA directory, the AppData folder is not present.
Which of the following should the technician do to see the appropriate folder?
Answer: B
Explanation:
The AppData folder is hidden by default in Windows, so changing the settings to view hidden items allows the technician to see and access the folder to delete the application's local data.
NEW QUESTION # 211
Which of the following filesystems allows a macOS to write data?
Answer: C
Explanation:
exFAT is supported by macOS for both reading and writing, making it a common cross-platform filesystem for external drives shared between macOS and Windows.
NEW QUESTION # 212
After a recent mobile OS upgrade to a smartphone, a user attempts to access their corporate email, but the application does not open. A technician restarts the smartphone, but the issue persists. Which of the following is the most likely way to resolve the issue?
Answer: C
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Mobile OS updates can sometimes cause compatibility issues with specific apps, including corporate email clients. The most likely resolution is to check for and apply an update to the affected application, especially if it hasn't been updated to support the latest OS version.
B). Registering with MDM might be required for access but wouldn't address app crashes due to incompatibility.
C). A third-party client might help, but it's not the best first step if the default app is expected to work.
D). Clearing the cache can help resolve some minor issues, but updating the app directly addresses compatibility concerns.
