Question #147
A remote user is unable to access files at home but can open the files at the office.
Which of the following should a technician check so the user can access the files both places?
- A . Network drive remote access
- B . Local user account
- C . Remote fileshare permissions
- D . Offline file settings
Correct Answer: D
D
Explanation:
One possible reason why a remote user is unable to access files at home but can open the files at the office is that the offline file settings are not configured properly. Offline files are a feature of Windows that allows users to access files and folders that are stored on a network drive even when they are not connected to the network. Offline files are cached copies of the network files that are stored on the local computer and synchronized with the network files when the connection is restored.
To use offline files, the user needs to enable the feature on their computer and on the network drive that contains the files they want to access. The user also needs to make sure that the files and folders they want to access are available offline, which means they are marked for offline synchronization. The user can check and change these settings by following these steps:
Open Control Panel and select Network and Internet > Sync Center > Manage offline files.
In the Offline Files window, click Enable offline files if the feature is disabled, and then click OK.
Restart the computer to apply the changes.
Open File Explorer and navigate to the network drive that contains the files and folders the user wants to access.
Right-click the files and folders and select Always available offline. A green sync icon will appear next to the items that are available offline.
To manually sync the offline files with the network files, open Sync Center and click Sync All.
By doing this, the user should be able to access the files and folders on the network drive even when they are at home or away from the office. However, the user should also be aware of some limitations and risks of using offline files, such as:
Offline files may not reflect the latest changes made by other users on the network, and may cause conflicts or errors when syncing.
Offline files may take up a lot of disk space on the local computer, and may affect the performance or stability of the system.
Offline files may be vulnerable to theft, loss, or damage if the local computer is not secured or backed up.
Therefore, the user should always backup their important files and folders, and use encryption or password protection to safeguard their offline files.

Question #150
A network technician needs to provide better wireless connectivity throughout a SOHO location.
Which of the following should the technician deploy to best improve connectivity?
- A . Access point
- B . Managed switch
- C . POE hub
- D . Wi-Fi router
Correct Answer: A
A
Explanation:
The correct answer is A) Access point.
An access point is a device that extends the wireless coverage of a network by creating a hotspot that allows wireless devices to connect to the network1. An access point can be connected to a router or a switch via an Ethernet cable or a wireless bridge1. By deploying one or more access points throughout a SOHO location, the technician can provide better wireless connectivity and eliminate dead zones or weak signals2.
A managed switch is a device that allows multiple devices to communicate on a network by forwarding data packets based on their destination addresses3. A managed switch can also provide advanced features such as VLANs, QoS, security, and remote management3. However, a managed switch does not improve wireless connectivity, as it only works with wired devices.
A POE hub is a device that provides power and data over a single Ethernet cable to devices that support Power over Ethernet (PoE) technology, such as IP cameras, VoIP phones, and wireless access points4. A POE hub can simplify the installation and placement of these devices by eliminating the need for separate power adapters or outlets4. However, a POE hub does not improve wireless connectivity by itself, as it still requires an access point or a router to create a wireless network.
A Wi-Fi router is a device that combines the functions of a router and an access point, providing both wired and wireless connectivity to a network and the internet. A Wi-Fi router can be used to create a SOHO network, but it may not be sufficient to cover the entire location with a strong and reliable wireless signal. To improve wireless connectivity, the technician may need to add additional access points or use a mesh Wi-Fi system that consists of multiple routers that work together to create a seamless wireless network.
Therefore, an access point is the best option among the choices to improve wireless connectivity throughout a SOHO location.
