AND REVISED!!
What is Cassandra storage used for? - - ..(ANSWER)...Timeseries metrics
How often are backups of Cassandra done? - - ..(ANSWER)...Daily; not incremental
What does Cassandra do to ensure there is no deduplication? - -
..(ANSWER)...Stores data that is replicated across nodes in the backup
What is Elasticsearch storage used for? - - ..(ANSWER)...RUM data
How often are backups of Elasticsearch done? - - ..(ANSWER)...Every 2 hours;
incremental
What is the procedure for Elasticsearch storing snapshots? - -
..(ANSWER)...Remove if older than 5 days; at least one per month kept
Why might you see gaps in deep monitoring data after a cluster backup restore?
What is the logic behind that reasoning? - - ..(ANSWER)...Transaction storage is
not backed up. Storage retention for this data is only 10 days, so from a long-term
perspective it is unnecessary.

When integrating ServiceNow, what does Dynatrace push to the SNOW ITOM
event API? - - ..(ANSWER)...All single events of a detected problem
Why might the ServiceNow integration fail? - - ..(ANSWER)...ITOM is enabled but
not activated in the SNOW instance
ServiceNow can schedule a job to pull what? - - ..(ANSWER)...Host, process, and
service information from Dynatrace
What are the Dynatrace app main modules in ServiceNow? - - ..(ANSWER)...-
Support

network interfaces in your environment.
What is VM ready time? What is an acceptable upper threshold? - -
..(ANSWER)...Percentage of time that a VM is ready but can't be scheduled to run
on a physical CPU.

2. Performance data is sent to the ActiveGate
3. Data from vCenter sent to Dynatrace for analysis
What are the two forms of authentication for connecting AWS instances to
Dynatrace? - - ..(ANSWER)...Key-based and roll-based authentication
How often does Dynatrace make calls to AWS CloudWatch API? - -
..(ANSWER)...Every 5 minutes
What is the going rate of polling the CloudWatch API - - ..(ANSWER)...$0.01 per 1k
