Answer: A,E

Explanation:

A. Prevent a device root – Rooting a device (gaining superuser access) can potentially increase security risks as it can give malicious apps unrestricted access to the system. Preventing root access would help secure the device.

B. Disable biometric authentication – Biometric authentication, such as fingerprint or face recognition, usually increases security because it’s harder to fake or guess than a traditional password. Disabling it wouldn’t necessarily enhance security.

C. Require a PIN on the unlock screen – While this is generally a good security practice, it may not prevent the installation of malicious applications, which seems to be the problem in this case.

D. Enable developer mode – Enabling developer mode usually reduces security as it opens up additional options not intended for typical users, which could be exploited by malicious apps or users.

E. Block a third-party application installation – Blocking third-party apps (apps installed from places other than the official app store) can significantly enhance security, as these sources often don’t have as rigorous vetting processes for apps. Malicious apps are more likely to be found outside the official app store.

F. Prevent GPS spoofing – While GPS spoofing can be a security concern, it’s not related to the problem of malicious apps slowing down the device.

So, to prevent the installation of malicious applications, the administrator should prevent a device root and block third-party application installation.
