Classic client compatibility
How do end‐users know they are accessing web‐based workflows in the Classic client? - ANSWER They don't. The transition of workflows from the Classic client to web‐based is seamless to end users.
Can a Classic client running Client Pack XYZ0‐25 work with a Hyperspace Web application running XYZ0‐24? - ANSWER Possibly, if the XYZ0‐25 Classic Client Pack did not introduce any additional dependencies on Hyperspace Web.
True or False? The Epic operational database environment will not forward you to a Hyperspace Web application URL if all instances of that application are unhealthy - ANSWER False. The environment has no insight as to which Hyperspace Web servers the applications live on. Nor does the environment communicate with the network appliance which does monitor Hyperspace Web application health.
True or False? The Epic environment selects which Hyperspace Web application URL you should go to when you launch a Hyperspace Web enabled workflow in the Classic client. - ANSWER False. The Epic environment picks which Hyperspace Web URL your Classic client session should use when the Classic client first connects to the environment.

TLS encryption is terminated at the load balancer without re‐encrypting. This is not best practice. Which of the following are reasons why? Choose one.
A. Traffic will move through ALL of your infrastructure unencrypted
B. Traffic will flow through PART of your infrastructure unencrypted
C. Performing SSL termination at the ELB significantly slows traffic
D. Performing SSL termination at the ELB will create issues with cookie‐based session affinity - ANSWER B is correct. If you perform encryption termination without re‐encrypting, the traffic between the load balancer and the HSW server will be un‐encrypted. Because this traffic could contain PHI, it is problematic if traffic is sent un‐encrypted.

A. Messages will route to the instance with the correct business services
B. Messages will route to the instance with the correct role
C. Messages will be routed to both instances at the same time
D. Messages may be sent to the wrong instance, resulting in broken functionality - ANSWER D.
The converse problem, by having to different instances shared the same listeners, results in message stealing, where messages go to instances that don't know how to process that type of message.
