It streamlines the process of adding, configuring, and managing endpoints within the Cisco TelePresence Management Suite environment. Synchronizing user permissions, integrating with cloud tools, and managing bandwidth allocation are functions performed by other components or features.

Explanation:
OAuth is commonly used for accessing Cisco Meeting Server APIs securely. It provides a standardized and secure method for authentication and authorization, allowing third-party applications to interact with Meeting Server APIs. Basic Authentication, LDAP Authentication, and SNMPv3 are used for other purposes and are not typically used for API access.

Explanation:
The primary benefit of using subzones in Cisco Expressway is improved bandwidth management and prioritization. Subzones allow administrators to segment network resources and apply bandwidth policies based on specific criteria, ensuring efficient use of available bandwidth. While subzones contribute to security and authentication, their primary purpose is bandwidth management.

Explanation:
A key advantage of using Cisco WebEx Hybrid Services is seamless integration with on-premises collaboration tools. This allows organizations to leverage existing investments in on-premises infrastructure while extending the capabilities of WebEx to the cloud. While enhanced security, improved video quality, and reduced latency are important, they are not the primary focus of Hybrid Services.
