Q 
An administrator needs to be able to control which apps are installed on the corporate net- work’s mobile devices, and update or delete them and their data as necessary. Which type of service do they need?
A. MAM
B. MDM
C. Location services
D. Device synchronization
A

A. MAM; Mobile application management (MAM) is a service that allows administrators to control corporate software on mobile devices, including updating and wiping apps. Mobile device management (MDM) controls which devices are on the network and can wipe entire devices. Location services does not manage software. Synchronization can back up apps and data but does not help with updates or deleting apps.

You are pairing a Bluetooth headset to a mobile device. On the mobile device, after finding the device for pairing, what is the next step to take?
A. Enable Bluetooth
B. Test connectivity
C. Enter the appropriate PIN code
D. Enable pairing

Q

What are the general step for pairing devices via Bluetooth?

A
  1. Enable Bluetooth.
  2. Enable pairing.
  3. Find a device for pairing.
  4. Enter the appropriate PIN code.
  5. Test connectivity.

For purposes of the exam, it’s best to memorize these steps. However, you might have noticed that in the exercises in this chapter (or in real life if you’ve paired your own devices), there are some slight nuances to understand:

  • Usually, the ability to pair is enabled if Bluetooth is enabled.Therefore, step 2 might not be needed, but you might need to initiate pairing.
  • It used to be that one device generated a PIN and you entered it into the other.Today, it’s more common to have both devices display a PIN, and you confirm on both devices that the PIN matches.

Q

When configuring an email client, Yahoo recommends IMAP for the the incoming mail. Why would IMAP be preferred?

A

IMAP is a clear choice because of its extensive interaction with the server, allowing the client to change the state or location of a mail item on the server without the need to download and delete it from the server.
