Which of the following scenarios would not typically warrant escalation to Tier 2 support?

In situations involving Tier 1 support, the priority is to handle common and straightforward issues effectively. A scenario where a customer requests a password reset typically falls under routine customer service procedures. This process is often well-defined, with clear guidelines and tools available for Tier 1 advisors to assist customers promptly, allowing for resolution directly at that level without the need to escalate to Tier 2 support.

On the other hand, other scenarios involve more complex issues requiring advanced troubleshooting or specialized knowledge. For instance, serial number discrepancies after repair might involve deeper investigative work regarding device history and warranty, while activation lock issues and problems connecting to a cellular network could require a more technical understanding of the device's configurations or account management that Tier 2 support is better equipped to handle. These factors highlight why a password reset request is generally within the purview of Tier 1 support, making it the correct response in this context.
