220-1102 Practice Test 10 — 10 Questions

Question 1

A user reports that an application fails to start because a configuration file is owned by root with permissions 644, but the application runs as user 'appuser'. Which command will allow 'appuser' to edit the file without changing ownership?

Accepted Answer

chgrp appgroup config.cfg && chmod g+w config.cfg. This tests understanding of file permissions and groups. By adding 'appuser' to the file's group and granting group write permission, the user can edit without being owner.

Answer

chmod 666 config.cfg

Answer

chown appuser config.cfg

Answer

setfacl -m u:appuser:rw config.cfg

Question 2

A customer reports that their Android phone's screen is unresponsive to touch after a drop. They can still hear notifications and see the display. Which built-in tool should you use to test the touchscreen functionality without relying on third-party apps?

Accepted Answer

Diagnostics Mode (e.g., *#0*#). This question tests knowledge of Android's built-in diagnostic tools. The correct answer is the 'Diagnostics' or 'Test' mode, often accessed via the dialer code or settings, which allows hardware testing without third-party apps. This is a standard feature for verifying touchscreen integrity after physical damage.

Answer

Safe Mode

Answer

Developer Options

Answer

Factory Reset

Question 3

During a security audit, a technician discovers that an employee's company-issued iPhone has been jailbroken. The employee claims they only did it to customize the home screen. Which security risk is most directly associated with a jailbroken device in a corporate environment?

Accepted Answer

It bypasses app sandbox restrictions, potentially exposing corporate data.. Jailbreaking removes the iOS sandbox restrictions that normally isolate each app's data and prevent unauthorized access to the file system. Without these restrictions, a malicious or compromised app on the jailbroken device can read, copy, or exfiltrate corporate data stored by other apps (e.g., email, VPN certificates, MDM profiles), directly violating data confidentiality in a corporate environment.

Answer

The device cannot receive iOS updates.

Answer

It voids the warranty.

Answer

The device will perform slower.

Question 4

A technician is tasked with deploying 50 Android tablets for a field sales team. The tablets need to have a consistent set of apps, settings, and security policies. The technician wants to avoid manually configuring each device. Which Android feature should the technician use?

Accepted Answer

Android Enterprise (Zero-Touch Enrollment). Android Enterprise Zero-Touch Enrollment allows IT administrators to provision devices automatically by associating them with a management provider (e.g., Samsung Knox, VMware Workspace ONE) via the manufacturer's portal. When the tablets are powered on and connected to Wi-Fi, they download a policy that enforces apps, settings, and security configurations without any manual intervention. This is the correct solution for deploying 50 tablets consistently.

Answer

Samsung DeX

Google Backup

Question 5

An iOS user complains that their iPhone will not connect to a known Wi-Fi network, but other devices on the same network work fine. Which iOS-specific troubleshooting step should you perform first to resolve this issue without erasing any personal data?

Accepted Answer

Use the 'Reset Network Settings' option in Settings > General > Reset.. The correct step is to use the 'Reset Network Settings' option in iOS, which clears saved Wi-Fi networks, VPN configurations, and other network-related settings without affecting personal data like photos or contacts. This often resolves stubborn Wi-Fi connection issues. A full factory reset or iCloud restore would be excessive and data-destructive.

Answer

Reset All Settings from the General > Reset menu.

Answer

Erase All Content and Settings to start fresh.

Answer

Restore the iPhone from an iCloud backup.

Question 6

A small business deploys 20 Android tablets for inventory management. The tablets must remain in a single app (the inventory app) and prevent users from accessing settings or other apps. Which Android feature should you enable to lock the devices into this single-app mode?

Accepted Answer

Use the Screen Pinning feature in Security settings.. Screen Pinning (option B) is the correct Android feature to lock a device into a single app. When enabled, it prevents users from leaving the pinned app, accessing the home screen, recent apps, or notification shade without entering a PIN or password. This is ideal for kiosk-mode deployments like inventory management tablets, as it restricts the device to exactly one application.

Answer

Enable Guest Mode from the user switcher.

Answer

Set up a separate user account with restricted profile.

Answer

Activate Factory Reset Protection (FRP).

Question 7

A technician is configuring a company-issued Android phone for a new employee. The employee will use the phone for both work (email, calendar) and personal activities. The company requires that work data be securely containerized and managed without affecting the employee's personal apps. Which Android feature should the technician enable?

Accepted Answer

Enable the Work Profile via the device's Settings under Accounts.. Android's Work Profile (part of Android Enterprise) creates a separate, managed profile on the device for work apps and data. This allows IT to enforce policies (like encryption and remote wipe) on the work profile without affecting the personal profile. Multi-User mode is for separate users, not a single user with two contexts, and Screen Pinning is for single-app lockdown.

Answer

Set up a separate User account for work.

Answer

Use Screen Pinning to lock the device to the email app.

Answer

Install a third-party MDM agent only.

Question 8

An iOS user is concerned about a lost iPhone and wants to ensure that if the device is erased, it cannot be reactivated without their Apple ID and password. Which iOS security feature provides this protection?

Accepted Answer

Activation Lock, enabled by Find My iPhone.. Activation Lock is an iOS security feature that is automatically enabled when Find My iPhone is turned on. It ties the device to the owner's Apple ID, preventing anyone from reactivating the device after it is erased or restored without entering the correct Apple ID and password. Find My iPhone locates the device, but Activation Lock provides the anti-theft protection. iCloud Keychain is for passwords, and Lost Mode locks the device but does not prevent reactivation after a wipe.

Answer

Find My iPhone location tracking.

Answer

iCloud Keychain with two-factor authentication.

Answer

Lost Mode in the Find My app.

Question 9

A technician is troubleshooting an Android device that is unable to connect to a corporate Wi-Fi network using WPA2-Enterprise with a username and password. The device connects successfully to other open Wi-Fi networks. Which Android setting should the technician check first to resolve the authentication failure?

Accepted Answer

Check if a CA certificate is installed and selected in the Wi-Fi network's advanced settings.. WPA2-Enterprise with username/password authentication typically requires a CA certificate to validate the RADIUS server's identity. Without a trusted CA certificate installed and selected in the Wi-Fi network's advanced security settings, the Android device will reject the connection attempt, even though the credentials are correct. This is the most common cause of authentication failure in enterprise Wi-Fi environments.

Answer

Verify that the device's IP address is set to DHCP.

Answer

Disable the proxy settings for that Wi-Fi network.

Answer

Configure a static MAC address on the device.

Question 10

A user reports that their Android phone automatically switches from Wi-Fi to cellular data when the Wi-Fi signal is weak, even though they want to stay on Wi-Fi. Which setting should you configure to prevent this behavior?

Accepted Answer

Disable 'Switch to mobile data' in Wi-Fi settings. The 'Switch to mobile data' or 'Smart Network Switch' option in Android Wi-Fi settings automatically transitions to cellular when Wi-Fi is weak. Disabling this keeps the device connected to Wi-Fi, addressing the user's complaint. This is a common mobile OS feature for network management.

Answer

Turn off Bluetooth

Answer

Disable 'Mobile data always active' in Developer Options

Answer

Enable Airplane Mode
