Which type of communication is blocked, when isolating the endpoint by clicking on the isolate...

When an endpoint is isolated inSymantec Endpoint Detection and Response (SEDR), the isolation blocks all network communication except for SEP and SEDR-related traffic. This selective blocking allows the endpoint to remain manageable by SEP and SEDR administrators while cutting off other potentially harmful network interactions.

How Isolation Works:

Isolation blocks allnon-SEP and non-SEDR network communications, effectively preventing the endpoint from connecting to or being accessed by other network entities.

This method helps contain threats while keeping the endpoint connected to management servers for monitoring or further response actions.

Why Other Options Are Incorrect:

All network communications(Option B) would prevent SEP/SEDR management traffic, which is contrary to the design.

Only SEP and SEDR network communications(Option C) is incorrect as it implies only SEP and SEDR are blocked, while in reality, all other traffic is blocked.

Only Web and UNC network communications(Option D) does not cover the full extent of the isolation functionality.
