installation engineer certification

[marionabil]

Hello ,

I have some questions in the installation engineer certification exam :-

1. When configuring multiple Application Servers for a single Blue Prism environment what must be considered ?
2. How can we ensure that all Runtime Resources in the environment are configured to only receive inbound INSTRUCTIONAL connections over SSL ?  
3. When should the Blue Prism setting “ Start the process engine on this machine when users sign in “ be disabled ?
4. How can a login agent Runtime Resource be instructed to login and immediately launch thick-client application and start processing work from a work queue ?

Thanks for support..

Please note that my reply isn't really from the perspective of the exam, but rather from a real-life implementation point of view.  

1. When you have multiple App Servers, any App Servers that have the scheduler enabled must be in the same time zone and synchronized, since the App Server is responsible for checking whether a schedule needs to be kicked off based off the machine's local time.  https://bpdocs.blueprism.com/bp-6-10/en-us/helpScheduler.htm?Highlight=time%20zone

If the encryption key(s) are being stored on the App Servers as opposed to in the Database, those encryption key files need to be the same and copied to each App Server.

2. https://bpdocs.blueprism.com/bp-6-10/en-us/sysman-settings.html?Highlight=inbound
There is a setting that you can tick to enable this. This setting requires that SSL certs are properly set up.  Since the communication is inbound to the RRs, your RRs would need to have individual (or wildcard) certs that are trusted by the Interactive Clients and Application Servers.

3. The Runtime Resource and Interactive Client can be run separately or together.  If the setting is enabled, it means that starting an IC will also start a RR.  This is appropriate when we are in development and QA environments when we will be using the IC a lot for testing.  The setting generally will not be used in production environments since there is no need to have a RR start up when we launch an IC.

4. I'm not sure about the word "immediately". But the way to get those tasks done in sequence (as opposed to immediately) would be to use the scheduler, and schedule the Login process to run.  Then you would leave an arbitrary buffer of time (say 2 minutes) to let Windows boot up completely and the Runtime Resource to launch.  Then you would schedule the process that you need to run.  So your schedule would look like: Login --> Wait X minutes --> Run process
