CompTIA Updated 220-1102 Exam Questions and Answers by angel

A passphrase is the most secure method among the options listed for preventing unauthorized access to a cell phone. Unlike a simple PIN or pattern, a passphrase is typically longer and can include a combination of letters, numbers, and special characters, making it harder to guess or brute force. Swipe and pattern locks are generally easier to bypass or observe due to smudge traces or pattern predictability. CompTIA A+ Core 2 security domain stresses using strong authentication methods to protect mobile devices, and passphrases are recommended for their complexity and strength. This aligns with mobile device security best practices covered in the official study guide, emphasizing strong, complex authentication mechanisms to secure sensitive data on mobile devices.

The ipconfig /all output shows the following:

IPv4 Address............ 192.168.0.74Subnet Mask............. 255.255.255.255Default Gateway......... 192.168.0.1

The issue with the subnet mask being set to 255.255.255.255 is that it specifies a single host subnet, meaning the device cannot communicate with other devices on the network or access the internet. The correct subnet mask for a typical home network should be:

Subnet mask of 255.255.255.0: This allows for communication within the same local network (192.168.0.0/24).

Default gateway 192.168.0.1: Correct, this is the typical address for the router.

IPv4 Address 192.168.0.74: Correct, within the correct subnet range.

Changing the subnet mask to 255.255.255.0 will resolve the connectivity issue.

Detailed Explanation with Core 2 References:Intrusion Detection Systems (IDS) monitor network traffic for malicious activities and alert administrators, helping to prevent malware infections before they can impact the network significantly. CompTIA Core 2 emphasizes the importance of implementing preventive measures like IDS to proactively detect and respond to potential threats (Core 2 Objective 2.3)​.

The user should configure extensions/add-ins. Since the issue involves a browser plug-in, checking if the extension or add-in is enabled or properly configured can resolve the issue. If the plug-in is disabled, the OTP prompt will not appear as expected.
