Detailed Explanation with Core 2 References:If multiple unsuccessful attempts led to the account being locked, the technician should unlock the account. Core 2 covers user account management practices, including unlocking accounts and managing failed login attempts (Core 2 Objective 2.5)​.

XFS is a high-performance filesystem created by Silicon Graphics in 1994 and is commonly used by Linux operating systems. It supports large files and directories and is known for its robustness and scalability. Other filesystems like NTFS (Windows), APFS (macOS), and HFS (macOS) are used on different platforms.

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.

Avoiding personal interruptions (such as browsing social media) shows respect and attentiveness, which is critical in building trust during customer interactions. Actively listening and taking notes demonstrates that the technician values the customer's concerns and is committed to resolving issues. Following up (A) and clarifying statements (D) are good but not immediate communication techniques during the interaction. Providing documentation (C) and maintaining attire (F) are operational but less relevant to active listening. Core 2 operational procedures highlight active listening and avoidance of distractions as key customer service skills to improve technician-customer communication.

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.

SSH (Secure Shell) is the secure protocol used for remotely accessing and managing network devices. It encrypts communication, ensuring confidentiality and integrity. Telnet provides remote access but is not secure because it transmits data, including passwords, in plaintext. TKIP is an encryption protocol for Wi-Fi security, not a remote access method. RDP (Remote Desktop Protocol) provides graphical remote desktop access mainly for Windows systems, not typically used for network device management. CompTIA A+ Core 2 clearly indicates SSH as the secure remote access protocol for network device administration.
