A.
Near-field communication.
B.
Rooting/jailbreaking
C.
Ad-hoc connections

NFC you are able to get applications like app beam to allow nfc transfers of applications. So it is a viable answer.

The correct answers are B and E:
Rooting/Jailbreaking Every mobile device comes from the factory with root access
protected from the user. This is an important aspect of all mobile operating systems,
as reserving root access enables the creator of the OS to update software, provide
containerization, and impede a number of security vulnerabilities that giving root access
would allow. When a user roots an Android system or jailbreaks an iOS system, they
are taking root access. Any good MDM software can detect this during onboarding or
during ongoing monitoring to let the organization know if this takes place.
One of the main reasons people root/jailbreak their mobile device is to grab applications
from third-party app stores that will not work as desired without root access (plenty of
third-party apps run on non-rooted or non-jailbroken phones as well). Whether you
root/jailbreak or not, third-party app stores are outside the control of Apple and Google
and do not provide any security. Figure 7-42 shows one third-party store for Android
apps, F-Droid.
Sideloading The standard Android installation file type is the APK file. Normally,
APK files are downloaded automatically from Web stores and installed. However, it is
possible to copy an APK file from a thumb drive, an SSD drive, or even across the
network or Bluetooth and install the APK file without any interference from a Web store.
This is called sideloading (Figure 7-43). Sideloading is risky because there are no safeties
on the installation media. Aside from agreements with employees not to sideload, there’s
no foolproof current mechanism to enforce or monitor a prohibition.
