Managed setup? correct answers Yes. It needs a publicly available IP address, a domain name
with a valid SSL certificate, and the domain must be different from web UI domain.

with external hosts, apps, sessions and synthetic monitoring? correct answers 2 Cluster
ActiveGates are recommended with the same domain name and certificate
What are the steps to take to use an Environment ActiveGate and a Cluster ActiveGate? correct
answers 1. Set up Dynatrace Manged cluster
2. Set up Cluster ActiveGate, make sure it can connect with Dyantrace Manged cluster. Make
sure Cluster ActiveGate has public IP address.
3. Set up Environment ActiveGate and provide Cluster ActiveGate public address for external
communication.
Is CMC web UI traffic accessed using HTTP or HTTPS? correct answers HTTPS
