220-1201 Mobile Device Network Connectivity — Timed 10 Questions

Question 1

A technician is troubleshooting a tablet that can connect to Bluetooth headphones but cannot connect to a Bluetooth keyboard. The keyboard is known to work with other devices. What should the technician check first?

Accepted Answer

Check if the keyboard is in pairing mode.. Bluetooth keyboards often require pairing in a specific mode, such as making the keyboard discoverable by pressing a button. If the keyboard is not in pairing mode, the tablet will not find it.

Answer

Ensure the tablet's Bluetooth is turned on.

Answer

Update the tablet's operating system.

Answer

Reset the tablet's network settings.

Question 2

A user complains that their smartphone frequently disconnects from the office Wi-Fi and then reconnects after a few seconds. The issue occurs only when the user walks to a specific part of the building. What is the most likely cause?

Accepted Answer

The smartphone is encountering a Wi-Fi dead zone due to building materials.. Wi-Fi signals can be blocked or weakened by building materials like concrete, metal, or thick walls. The user is likely entering an area with poor signal coverage, causing the device to disconnect and then reconnect when moving back into range.

Answer

The smartphone's battery saver mode is turning off Wi-Fi.

Answer

The office access point is overloaded with too many connections.

Answer

The smartphone's Wi-Fi antenna is loose.

Question 3

A technician is configuring a smartphone for a user who frequently travels internationally. The user wants to avoid high roaming charges but still use data when connected to local Wi-Fi. What should the technician do?

Accepted Answer

Disable cellular data in the mobile network settings.. Disabling cellular data ensures the device only uses Wi-Fi for internet access, preventing accidental roaming charges. The user can still connect to local Wi-Fi networks for data.

Answer

Enable airplane mode and then turn on Wi-Fi.

Answer

Enable data roaming.

Answer

Set the device to 2G only.

Question 4

A user reports that their smartphone's mobile hotspot stops working after a few minutes of use. The laptop connected to it loses internet access. What is the most likely cause?

Accepted Answer

The smartphone's hotspot timeout setting is enabled.. Many mobile carriers and device manufacturers impose a timeout on hotspots to conserve battery and data. The hotspot may automatically turn off after a period of inactivity or after a set time.

Answer

The laptop's Wi-Fi adapter is faulty.

Answer

The smartphone's cellular signal is too weak.

Answer

The laptop has a static IP address configured.

Question 5

A customer reports that their smartphone can connect to Wi-Fi at home but fails to connect to the company's 5 GHz Wi-Fi network in the office. Other devices connect fine. What is the most likely cause?

Accepted Answer

The smartphone is too far from the office access point for 5 GHz.. The 5 GHz band has shorter range and is more easily blocked by walls and obstacles. The customer's device may be too far from the access point or there may be interference, causing the connection to fail while 2.4 GHz remains available.

Answer

The smartphone's Wi-Fi antenna is damaged.

Answer

The office access point is configured for 2.4 GHz only.

Answer

The smartphone's Wi-Fi driver needs updating.

Question 6

A user reports that their smartphone's mobile hotspot works for a few minutes, then the connected laptop loses internet access, but the smartphone still shows a cellular data connection. The hotspot remains enabled. What is the most likely cause?

Accepted Answer

The carrier is throttling the hotspot data after a usage threshold.. Carrier throttling can reduce data speeds after a certain amount of data is used, making the connection too slow for practical use. This is common on unlimited plans that throttle after a threshold, and the hotspot may still appear active but with severely limited throughput.

Answer

The smartphone's battery saver mode is limiting hotspot performance.

Answer

The laptop's Wi-Fi adapter is overheating.

Answer

The smartphone is switching to a different cellular band.

Question 7

A technician is deploying a fleet of tablets for field workers. The tablets need to connect to a cellular network for data, but the company wants to minimize data usage. Which setting should the technician configure on each tablet?

Accepted Answer

Enable data saver mode.. Limiting background data prevents apps from using data when not in active use, which significantly reduces overall data consumption. This is a common practice for managing data usage on mobile devices.

Answer

Disable Wi-Fi.

Answer

Enable airplane mode.

Answer

Set the preferred network type to 5G.

Question 8

A user's smartphone can send and receive text messages but cannot access the internet over cellular data. Wi-Fi internet works fine. Which setting is most likely misconfigured?

Accepted Answer

The APN settings are incorrect.. APN settings define how a device connects to the carrier's data network. If the APN is incorrect or missing, the device can still use SMS (which uses a different channel) but cannot establish a data connection.

Answer

The Wi-Fi hotspot is enabled.

Answer

Bluetooth is turned on.

Answer

The device is in roaming mode.

Question 9

A technician is troubleshooting a smartphone that cannot connect to any Wi-Fi network. The technician has already verified that the device's Wi-Fi adapter is enabled and that other devices can connect to the same networks. What should the technician check next?

Accepted Answer

Check if the device has a static IP address configured.. A static IP address can prevent a device from obtaining a valid IP from the DHCP server, causing connection failure. This is a common issue when a device has been manually configured with an IP that is not in the network's range or is already in use.

Answer

Check the device's MAC address filter on the router.

Answer

Check if the device's date and time are correct.

Answer

Check if the device's Bluetooth is interfering.

Question 10

A user is setting up a new tablet and wants to share its internet connection with a laptop that has no cellular capability. The tablet has a cellular data plan. Which configuration should the user enable on the tablet?

Accepted Answer

Enable Wi-Fi hotspot.. Tethering allows a mobile device to share its cellular internet connection with other devices via Wi-Fi, Bluetooth, or USB. This is the standard method for providing internet access to a non-cellular laptop.

Answer

Enable Bluetooth pairing only.

Answer

Enable airplane mode.

Answer

Enable NFC.
