Question 1 of 30
In a Cisco Unified Communications Manager (CUCM) environment, you are tasked with implementing Transport Layer Security (TLS) to secure SIP signaling between endpoints and the CUCM server. You need to ensure that the TLS configuration adheres to best practices for certificate management and encryption standards. Given a scenario where you have multiple endpoints from different manufacturers, which of the following considerations is crucial for ensuring successful TLS communication across all devices?
Ensuring that all endpoints trust the same Certificate Authority (CA) that issued the CUCM server's certificate.
Configuring each endpoint with a unique self-signed certificate to avoid trust issues.
Using only the latest version of TLS (TLS 1.3) for all communications, regardless of endpoint capabilities.
Disabling certificate validation on all endpoints to simplify the connection process.
