Correct Answer. C. Set up the projector in extended desktop mode Setting up the projector in extended desktop mode allows the user to use the laptop and projector as two separate displays, showing different content on each.
Option A is incorrect because Display Mirroring would show the same content on both screens, which is not suitable for this scenario Option B is incorrect because making the projector the primary display does not independently affect content shown on each screen Option D is incorrect because brightness settings affect visibility but not how content is displayed across multiple screens

Correct Answer. A. Ensure the email server address is entered correctly Entering the correct server address is crucial for connecting to the email server. A typo or outdated server address can prevent the device from establishing a connection.
Option B is incorrect because reinstalling the app should only be considered if there are indications that the app is malfunctioning, not simply due to connection errors Option C is incorrect as restarting the device does not address potential incorrect settings within the email setup Option D is incorrect because changing the password does not resolve server connection issues and is unrelated to server reachability

Correct Answer. A. That the router has the correct subnet masks configured for each interface Incorrect subnet masks can prevent routing between interfaces on a router, leading to connectivity issues between subnets.
Option B is incorrect. While DHCP is important for IP address assignment, it does not directly resolve routing issues between subnets.
Option C is incorrect. The category of network cables would impact physical connectivity and data rates but not routing between subnets.
Option D is incorrect. While firewall settings are crucial, the first check should be the configuration that directly impacts routing.

Correct Answer. A. HDMI to DVI-D An HDMI to DVI-D adapter is the most suitable choice for connecting modern computers with HDMI outputs to older monitors with DVI inputs, as DVI-D supports digital signals, which are compatible with the digital signals from HDMI.
Option B is incorrect because while HDMI to DVI-I would technically work (since DVI-I supports digital signals), it is less common and potentially more expensive due to its dual compatibility with analog signals, which is unnecessary in this case.
Option C is incorrect because HDMI to DVI-A involves converting a digital signal to an analog format, which could result in loss of signal quality and is generally not recommended.
Option D is incorrect because DVI-X does not exist as a recognized standard.

The Dropbox application allows for the creation of a synchronized folder that behaves much like a local directory, automatically syncing files and folders between Dropbox and the user's computer, providing an easy and efficient way to access files stored in Dropbox.
Option A is incorrect because Dropbox does not support direct FTP access for file synchronization or mapping.
Option C is incorrect because SMB protocol is not used for direct integration with cloud storage services like Dropbox without specific third-party software or configurations.
Option D is incorrect because although it is possible, it's not the most straightforward method compared to using the native Dropbox application, which provides robust support and integration.
