CompTIA Cloud+ (CV0-002) — Question 12

A company is deploying a new instant messaging app to allow for communications with external vendors. Each entity will host its own version of the application, but users must be able to talk between the companies. Which of the following security techniques would MOST likely be used to allow this to happen?

Answer options

Correct answer: C

Explanation

Public federation is the correct answer as it enables different organizations to share access and communicate securely across their respective systems. User synchronization and password synchronization do not address cross-organization communication effectively, while multifactor authentication focuses on verifying user identity rather than facilitating inter-company messaging.
