Lesson 8: Supporting Mobile Devices Flashcards
You are writing a knowledge base article for remote staff members who need to use their smartphones to provide Internet connectivity to their laptops. Two options to facilitate this include configuring a hotspot or the use of tethering. What distinguishes the two options?
Configuring a hotspot allows the laptop to connect to the smartphone over Wi-Fi. Tethering means connecting the laptop via USB or Bluetooth.
What type of peripheral port would you expect to find on a current generation smartphone?
USB-C
(Apple’s iPhone 15 has now moved to USB-C)
You are identifying suitable smartphone models to issue to field sales staff. The models must be able to use digital payments. What type of sensor must the devices have?
Near-field communications (NFC) allow the user to touch the phone to a point-of-sale terminal to authorize payment in conjunction with a wallet app.
You are assisting a user with pairing a smartphone to a Bluetooth headset. What step must the user take to start the process?
Enable discoverability
On the smartphone, open the Bluetooth page under Settings. This will make the phone discoverable and enable the user to find nearby devices. If the headset is not found automatically, check if there is a button on the headset to make it discoverable.
A company is ordering custom-built laptops to supply to its field sales staff for use predominantly as presentation devices. The company can specify the type of panel used and has ruled out IPS and OLED on cost grounds. Which of the remaining mainstream display technologies is best suited to the requirement?
Vertical alignment (VA) displays support good viewing angles and high-contrast ratios, which makes them well-suited to displaying slides to an audience. The twisted nematic (TN) type is cheap but does not support wide-angle viewing.
Why must a vendor account usually be configured on a smartphone?
A vendor account, such as an Apple, Google, or Samsung account, is required to use the app store.
Which types of data might require mapping between fields when syncing between applications?
Contacts and calendar items
How do you configure an autodiscover-enabled email provider on a smartphone?
Just select the provider then enter the email address. If the account is detected, you will be prompted for the password.
A company has discovered that an employee has been emailing product design documents to her smartphone and then saving the files to the smartphone’s flash drive. Which technology can be deployed to prevent such policy breaches?
Mobile application management (MAM) allows an enterprise to create a protected container as a workspace for corporate apps and data and prevent copying to other storage areas.
What type of standard adapter card might be used to connect internal FRU devices to the motherboard of a laptop? (3)
1) Mini-PCIe
2) mSATA
3) M.2
Several laptops need to be replaced in the next fiscal cycle, but that doesn’t begin for several months. You want to improve functionality as much as possible by upgrading or replacing components in some of the laptops that are having problems. Which items are most easily replaced in a laptop?
The fixed drive, system memory (RAM), and plug-in wireless card will be the easiest upgradable components to install. If items need repairing, the battery, touchpad, and the keyboard should be straightforward to replace, if you can obtain compatible parts.
A technician is performing a keyboard replacement and asks for your help. The data cable for the old keyboard will not pull out. How should it be removed?
This type of flat data connector is secured by a latch. Pop the latch up before trying to remove the cable
What is the process for installing memory in a laptop? (5 steps)
1) Verify that the DDR version of the upgrade module is supported by the motherboard.
2) Take antistatic precautions.
3) Locate the memory slot, which is usually accessed via a panel on the back cover.
4) Move the connector up to 45º and insert the memory card, taking care to align it correctly.
5) Push the card flat again.
A laptop user reports that they are only getting about two hours of use out of the battery compared to about three hours when the laptop was first supplied to them. What do you suggest?
Batteries lose maximum charge over time. It may be possible to recondition the battery or to use power-saving features, but the only real way to restore maximum battery life is to buy a new battery.
You received a user complaint about a laptop being extremely hot to the touch. What actions should you take in response to this issue?
Overheating can be a sign that dust and dirt is restricting the necessary airflow within the device, so start by cleaning the ventilation duct with compressed air, and then make sure that the device is getting proper air circulation around the outside of the case, such as by supplying a chiller pad.
A user complains that their Bluetooth keyboard, which has worked for the last year, has stopped functioning. What would you suggest is the problem?
The batteries in the keyboard have run down—replace them
If the laptop can display an image on an external monitor but not on the built-in one, which component do you know is working, and can you definitively say which is faulty?
The graphics adapter is working. The problem must exist either in the cabling to the built-in screen or with a screen component, such as an inverter, backlight, or the display panel itself. Further tests will be required to identify which.
A laptop user is complaining about typing on their new laptop. They claim that the cursor jumps randomly from place to place. What might be the cause of this?
The user could be touching the touchpad while typing, or vibrations could be affecting the touchpad. Update the driver or reduce the sensitivity/disable touch and tap events.
