Everything else) [T / F 1] If a device is stolen, you can disable the camera on the phone, as this is no way to ID a thief with a stolen phone. [T / F 2] You can remotely back up data from the phone to a server first and display a "Lost/stolen phone—return to XX" message on the handset. [T / F 3] Device encryption prevents an attacker in possession of the device from retrieving the encryption key because the information remains inaccessible.

D) Remotely use Location Services and geotracking (HINT: the former, the latter.). Everything else) {T / F 1] FALSE (ENABLE the camera! It has been reported that sometimes the thief has been captured using the photos taken in this manner.) [T/ F 2] TRUE. [T / F 3] TRUE.

You are setting up a new iPhone for an end-user. What can you implement to streamline the user's credentials? A) Have the user create multiple accounts on multiple apps. B) Prevent the automatic loading of profiles when using an Apple ID. C) Remove the ability to authenticate with the user credentials on vendor cloud services. D) SSO (Single Sing On) can be implemented with one set of credentials. Correct Answer) Here, one service accepts the credentials from another service, meaning you authenticate once to access many services. Everything else) 1) Works on the logical & essential basis that when you sign into Google, for example, you are also signing in to email, maps, YouTube, search, and so on. 2) Is frowned upon by users because any sort of overuse of registration requisites can be a barrier to a user choosing to continue to use the app. [T/F] When you associate your iPhone with an Apple ID and unlock it, an SSO app on that iPhone will identify that you are signed in as your ID and load the appropriate profile for you automatically.

Everything else) [T / F 1] If you have a Windows PC and an Apple iPhone, you will have to manage two sets of apps, including managing social media pages. [T / F 2] A criminal can easily get information about where someone lives and then identify when they are on holiday from social media in image metadata; this is due to how if someone posts pictures online, most will be tagged with location information.

D) Your phone social media data is pretty much the same as your PC social media data. [T/ F 1] FALSE (Apps between different devices) will share data seamlessly, however, such as social media. [T / F 2] TRUE.

Which of these is the best standard format for maintaining contacts?
