Correct Answer. B. Check if their device meets the application's system requirements Ensuring that the device meets the minimum system requirements of the application is critical, especially when dealing with large files that may require more resources.
Option A is incorrect because uninstalling and reinstalling the application should be considered only after simpler checks, like system requirements, have been verified.
Option C is incorrect as upgrading the application does not necessarily resolve a resource constraint issue.
Option D is incorrect because changing the file format might not address the underlying issue if the application is struggling due to resource limitations.

Informing the user and requesting permission not only adheres to ethical guidelines but also maintains transparency and builds trust during the remote support process.
Option A is incorrect because accessing sensitive files without user consent can violate privacy and trust.
Option C is incorrect because it may prevent the technician from fully resolving the issue if file access is crucial.
Option D is incorrect because recording the session without consent is unethical and could violate both legal and company policies.

Correct Answer. D. ss dport == :80 ss dport == :80 filters the output to show all connections where the destination port is 80, useful for monitoring potential flooding or other issues on specific server ports.
Option B is incorrect. ss src :80 would incorrectly filter by source port, not the destination, which isn't useful for monitoring incoming traffic to a port.
Option C is incorrect. ss sport == :80 filters by source port, which isn't relevant for checking incoming connections on a specific port.

Correct Answer. B. Test the speed using a network testing tool and check the Ethernet cable for damage Using a network testing tool to check the connection speed and inspecting the physical state of the Ethernet cable can help identify if the issue is related to cable damage or other network bottlenecks.
Option A is incorrect. Replacing the Ethernet cable with fiber optic is impractical and unlikely to address issues specific to one workstation.
Option C is incorrect. RAM increases general computing performance but would not specifically affect network speeds.
Option D is incorrect. While connecting to WLAN could offer diagnostic insights, it doesn't directly resolve the issue or identify the cause of slower speeds on the Ethernet connection.

Correct Answer. B. Check her membership in the appropriate security group The first step should be to verify if Sarah is still a member of the security group that has permission to access the shared document folder, as changes or updates in group memberships might have inadvertently removed her.
Option A is incorrect because there is no indication that her password is the issue, as she can log in but cannot access specific resources.
Option C is incorrect as network driver issues would typically prevent her from accessing all network resources, not just a specific folder.
Option D is incorrect because upgrading her to administrative privileges can pose a security risk and does not address the underlying access issue.
