True or False: Customers can open technical support cases through Cisco TAC.

Customers can indeed open technical support cases through Cisco's Technical Assistance Center (TAC). This service is a key component of Cisco's commitment to providing support for its products and services. By enabling customers to directly contact TAC, Cisco ensures that users have access to expert assistance, whether they are troubleshooting issues, seeking guidance on configurations, or needing help with product features.

This direct access to Cisco TAC is essential for a swift resolution of technical issues, reinforcing the importance of customer support in maintaining the reliability and performance of Cisco's solutions. The other choices incorrectly suggest limitations on the ability to open support cases—either through partners, by plan type, or invalidly stating that customers cannot reach TAC directly. This highlights the broad accessibility that Cisco provides to its customers for support.
