Which three features are required to accomplish this goal?

You are responding to a proposal request from an enterprise with multiple branch offices. All
branch offices connect to a single SRX device at a centralized location. The request
requires each office to be segregated on the central SRX device with separate IP networks
and security considerations. No single office should be able to starve the CPU from other
branch offices on the central SRX device due to the number of flow sessions. However,
connectivity between offices must be maintained. Which three features are required to
