DYNATRACE PRO TEST PAPER QUESTIONS AND
SOLUTIONS RATED A+
✔✔In Dynatrace Managed deployment scenario 1: basic setup, what is each
communication channel secured with? - ✔✔TLS (Transport layer security)

ActiveGate? - ✔✔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.
