Question 7

A company is deploying mobile devices for its sales team. The devices need to access corporate email and calendars securely. Which THREE features are most important for managing these devices centrally?

Accepted Answer

Remote wipe capability. Option B (Remote wipe capability) is correct because if a sales device is lost or stolen, IT can erase corporate email, calendars, and cached credentials remotely, preventing data leakage of sensitive business communications. Option D (GPS tracking) is correct because location tracking lets administrators locate lost or stolen devices and enforce geofencing or location-based compliance policies for devices holding corporate data. Option E (Mobile Device Management (MDM) software) is correct because MDM is the central platform that enforces email/calendar access policies, configures Exchange ActiveSync or modern auth profiles, applies encryption and passcode requirements, and orchestrates remote wipe and GPS functions across the fleet. Option A (NFC for mobile payments) is not required for secure corporate email and calendar access, and option C (high-resolution camera) is a consumer hardware feature unrelated to centralized device management or data security.

Answer

NFC for mobile payments

Answer

High-resolution camera

Question 8

A user wants to synchronize files across multiple devices, including an iPhone, a Windows laptop, and an Android tablet. Which TWO cloud services would be most effective for this cross-platform syncing?

Accepted Answer

OneDrive. OneDrive (B) is correct because Microsoft's OneDrive client is available for iOS, Android, Windows, and the web, allowing the same files to be synced and accessed across an iPhone, Windows laptop, and Android tablet. Google Drive (C) is also correct because Google provides Drive apps for iOS, Android, Windows, and the web, enabling cross-platform file synchronization among those exact devices. Bluetooth file transfer (A) is not a cloud service and only supports short-range, manual device-to-device transfers, so it does not synchronize files across multiple devices. iTunes sync (D) is designed primarily for Apple device management and local syncing with a computer, not cloud-based cross-platform synchronization. iCloud (E) is not the best fit here because, while it has some Windows and web support, it is optimized for Apple's ecosystem and does not natively sync files on Android devices.

Answer

Bluetooth file transfer

Answer

iTunes sync

Answer

iCloud
