Host pool Pool1 configuration: Pooled, Load balancing algorithm: Breadth-first, Max session limit: 5, Start VM on connect: Yes. Given the current session hosts (as provided), how many additional users must connect to Pool1 to start Host3?

The host pool is configured for breadth-first load balancing and has a maximum session limit of 5 per host. Breadth-first load balancing distributes new user sessions evenly across all available session hosts until each host reaches its maximum session limit. Currently, Host1 has 4 sessions and Host2 has 5 sessions. To start Host3, Host1 must first reach its maximum session limit of 5. This requires 1 additional user (5 - 4 = 1). Once Host1 is full, new sessions will attempt to go to Host2. Host2 is already at its maximum of 5 sessions. Therefore, after Host1 is full, 5 more users will attempt to connect, but will be unable to connect to Host1 or Host2. These 5 users, plus the 1 user needed to fill Host1, will trigger the start of Host3. Total users needed: 1 (for Host1) + 5 (to exceed capacity of Host1 and Host2) = 6. Incorrect options: 1: This would only fill Host1. 3: This would fill Host1 and attempt to connect to Host2, but not enough to start Host3. 5: This would fill Host1 and attempt to connect to Host2, but not enough to start Host3. 10: This is more than necessary to start Host3.
