Explanation: A smartphone that takes more than a day to fully charge may be due to a charger that is not powerful enough. The technician should verify that the charger is rated for the smartphone’s battery capacity and that it is providing the correct voltage and amperage123.
A Wi-Fi mesh network has been optimized to eliminate poor coverage areas, yet users still experience decreased bandwidth and connectivity issues. Which of the following actions should the technician take NEXT?
A. Relocate any large, dense, solid, and metal objects, such as mirrors and file cabinets, in the mesh network coverage area to the perimeter so that wireless reflections, absorptions, and occlusions are minimized.
B. Use a Wi-Fi analyzer to determine whether the channel in use is overcrowded and to identify which channel the mesh network should use for best performance.
C. Use the signal strength indicator on a mobile device to roam the coverage area and generate a heat map to isolate zones with weak signals.
D. Turn off broadcasting of the SSID on the mesh network so that other networks cannot see it.
Explanation: If users are experiencing decreased bandwidth and connectivity issues in a Wi-Fi mesh network, the technician should use a Wi-Fi analyzer to determine whether the channel in use is overcrowded and to identify which channel the mesh network should use for best performance.

A user regularly travels to multiple sites to take pictures with a mobile device and transfers those pictures to a computer via a removable SD card. Recently, the SD card was damaged and had to be replaced. Now, the user is unable to save pictures to the new SD card. Which of the following should the user verify first so pictures can be saved to the SD card?
A. The card is correctly formatted.
B. The card is a storage device.
C. The card is not locked.
D. The card is initialized.
Explanation: When a user is unable to save pictures to a new SD card after replacing a damaged one, the first thing to check is whether the card is locked. Many SD cards have a physical switch on the side that can be toggled to a "locked" position, which prevents data from being written to the card. Ensuring the switch is in the "unlocked" position allows the device to save data to the SD card.
A technician is upgrading a user’s laptop from an HDD to an SSD. The user's laptop only has a single bay for a hard drive. Which of the following characteristics of the SSD is the most important in this scenario?
A. Partition type
B. Storage size
C. Form factor
D. Transfer speed
Explanation: When upgrading a laptop's storage from an HDD to an SSD, especially in laptops with only a single bay for a hard drive, the most critical characteristic to consider is the form factor. The form factor must match the physical dimensions and interface of the original HDD to ensure that the SSD can fit into the bay and connect properly. Storage size
(B) is important for capacity reasons, transfer speed
(D) affects performance, and partition type
(A) is a software configuration aspect, but the form factor
(C) is crucial for the physical compatibility of the SSD with the laptop.
