Show Suggested Answer

Suggested Answer: A 🗳️
Layer 7 load balancing benefits include:
✑ Needs only a single IP address.
✑ Inspects content and can direct traffic.
✑ Provides notification of failed service that can be taken offline.
✑ Handles load balancer SSL termination.
Distributes traffic at the application layer and understands the destination URL.
From scenario:
✑ Load balancing must support the following functionalities:
✑ Provide SSL termination
✑ Remove failed Mailbox servers from the server pool.
Data collected by Managed Availability from Outlook on the web must be used.

✑ Target server health must be configured as per-protocol so that only the affected client protocol is directed to another server if a server fails.
