A company asked an architect to design a VMware Horizon View 7.1 solution utilizing security servers to support 7500 local network users and 3500 remote sales personnel.
These requirements were requested:
✑ Design must provide high availability
✑ Design must use VMware's supported minimum number of connection servers
✑ All users will connect with BLAST or PCoIP
Which two minimums can the architect recommend to meet requirements? (Choose two.)
To meet high availability requirements, you need redundancy. Each VMware Horizon View Connection Server can support a maximum of 2000 concurrent users when utilizing BLAST or PCoIP protocols and security servers. For the 7500 local users, you need 4 connection servers because if one fails, the remaining servers must still support the load, supporting 4000 users (2000 each for high availability). So, you need an additional one for failover, totaling 3 connection servers (3 x 2000 = 6000 + 1 for HA). For the 3500 remote users, using 2000 per server requires 2 servers for 4000 users plus an additional server for high availability, making it a total of 2 connection servers (that sum up to 4000 users, with one spare for failover). Hence, the recommended minimums are 2 connection servers for remote users and 3 connection servers for local users.
BD is correct PCoIP Secure Gateway connection and Blast Secure Gateway connection (thru Security Servers) = 4000 max connections. With HA you need 1+1=2 for remote and 2+1=3 for local users. https://docs.vmware.com/en/VMware-Horizon-7/7.1/com.vmware.horizon-view.planning.doc/GUID-1AC83D7C-BDC6-4E32-A35C-652107BDB6D0.html#maximum-connections-for-view-connection-server-2
I think BD is correct. Question states solution must be highly available therefore you will need 3 connection servers for internal users as each connection server will support 4,000 users. If one failed and there is only 2, the solution is not highly available.
CD, Internal is 4000 users per CS but HA adds one = 3 External is 2000 users per CS as they are tunneled through Security or UAG which are bound to Connection servers. 3500 require 2 CS + HA = 3 servers So C & D

I agree. https://kb.vmware.com/s/article/2150348
For remote users, it's enough 1 connection server plus 1 for availability
Here is an example from VMware's own documentation regarding sizing which is similar to this question:- "For example, if you had 20,000 users, with 16,000 of them inside the corporate network, you would need 5 Connection Server instances inside the corporate network. That way, if one of the instances became unavailable, the 4 remaining instances could handle the load. Similarly, for the 4,000 connections coming from outside the corporate network, you would use 2 Connection Server instances so that if one became unavailable, you would still have one instance left that could handle the load." https://docs.vmware.com/en/VMware-Horizon/2203/horizon-architecture-planning/GUID-1AC83D7C-BDC6-4E32-A35C-652107BDB6D0.html I believe the answer is B & D
Security servers can only handle 2000 connections though. n+1 = 3 for both cases https://docs.vmware.com/en/VMware-Horizon-7/7.13/horizon-architecture-planning/GUID-1AC83D7C-BDC6-4E32-A35C-652107BDB6D0.html#:~:text=Although%20a%20single%20security%20server,to%20use%202%20or%204.
C,D What for HA ?
As you know the recommended number of active session per CS is 2000 : https://kb.vmware.com/s/article/2150348 So i agree with B&D
