What is 2G in wireless networks?
Second-generation wireless technology for basic voice and text communication.
What is 3G used for?
Third-generation wireless technology that supports faster data speeds and basic video calls.
What is the main advantage of 4G networks?
High-speed internet and better support for multimedia and streaming.
What does 5G provide over 4G?
Significantly faster speeds, lower latency, and support for IoT devices.
How can cellular data be disabled on mobile devices?
By toggling the cellular data option in the settings menu.
What is a mobile hotspot?
A feature that shares a mobile device’s internet connection with other devices via Wi-Fi.
What is tethering in the context of hotspots?
Using a physical connection like USB to share a mobile device’s internet.
What is GSM in wireless networks?
Global System for Mobile Communications, a standard for cellular networks primarily in Europe.
What is CDMA in wireless networks?
Code-Division Multiple Access, a cellular technology used in the US, especially by older Verizon networks.
How do GSM and CDMA differ?
GSM uses SIM cards for device authentication, while CDMA ties devices to the network through the phone itself.
What does a Preferred Roaming List (PRL) do?
It determines which cellular towers a device connects to when roaming.
Why is PRL important for mobile devices?
It optimizes connectivity and ensures devices connect to the preferred networks.
What happens if the PRL is outdated?
The device may not connect to the best available network, leading to poor service.
What is roaming in cellular networks?
Using a network outside of the device’s home carrier coverage area.
How can roaming be enabled/disabled?
Through the roaming settings in the mobile network settings menu.
What is the role of MDM in mobile devices?
To manage, secure, and monitor mobile devices within an organization.
What is Mobile Application Management (MAM)?
It manages and secures specific applications on mobile devices.
What is corporate email configuration in MDM?
Setting up company email accounts on mobile devices with security policies.
Why is corporate email configuration important?
It ensures secure access to company email and enforces IT policies.
What is two-factor authentication (2FA)?
A security measure requiring two forms of verification to access accounts.
How does MDM enforce 2FA on mobile devices?
It requires 2FA settings for accessing corporate accounts and systems.
What are corporate applications in MDM?
Applications required for work, such as collaboration and productivity tools.
How does MDM manage corporate applications?
It installs, updates, and restricts applications as needed for security.
What is the purpose of application whitelisting in MDM?
To allow only approved apps to be installed on devices.
What is geofencing in MDM?
Restricting device usage based on geographic location.
What happens when a mobile device violates MDM policies?
It can be locked, wiped, or restricted to secure company data.
What is containerization in MAM?
Separating corporate apps and data from personal data on the device.
Why is containerization important for mobile devices?
It ensures company data remains secure, even on personal devices.
What is the purpose of remote wipe in MDM?
To erase company data from a mobile device in case of loss or theft.
How can a mobile device be enrolled into an MDM system?
By installing an MDM agent or profile provided by the IT department.
