How can Dynatrace use log files to aid in problem detection?
If enabled, Dynatrace uses the Analyze Process Logs utility to detect problems in log files.
You can identify log patterns that indicate availability related problems. Dynatrace will detect appearence of these patterns and raise an event
You can define search terms for files. Dynatrace Will search in problem event related log files and raise an event when the terms are located.
Dynatrace cannot be configured to use Log Files with problem detection.
You have adjusted the anomaly detection settings for an application to detect an increase in
failure rate with fixed thresholds. What option do you set to ensure there is a high confidence

Davis has suppressed alerts and is not creating new problems for an event it has detected as
a 'frequent issue'. Under what conditions will Davis raise a new problem and alert for the
event?
When there is any change to the previously detected frequency or duration of the event
When the frequency of the event occurrence hasn't changed, but the duration of each event
has decreased
When the severity increases for the event. For example, the frequency is the same but the event has a longer duration than previously detected
Problems and alerts are never suppressed automatically, you need to manually close the problems you determine are frequent issues
How does the Dynatrace API prevent an overload of requests in a SaaS environment?
Dynatrace sets a limit on the number of IP sessions per minute.
Developers must code a check to limit the number of requests.
Dynatrace sets a throttling limit on the concurrent API requests
Dynatrace limits the number of HTTP requests per second
You've received a "Max. user actions per minute exceeded" message, how does this impact
your monitoring data?
No user sessions will be captured until the overall traffic volume drops
The number of user sessions captured will be throttled until the overall traffic volume drops
There is no change in the user sessions captured but the collection of rate metrics will be terminated to prevent skewed statistics.
There is no change in the user sessions captured but the user action per minute limit must be increased

Dynatrace automatically monitors process groups that are of a known technology or consume
a lot of resources. How do you tell Dynatrace to monitor a process group which is important
to you, but is unknown to Dynatrace?
Enable the built-in detection rule that detects all running processes and will label unknown process groups. You can then define the details for the process group
Create a Process availability monitoring rule to detect if there is at least one resource-consuming process running in your process group.
With Process group naming rules that allow you to define a name for the process group
Use Declarative process grouping to define detection rules for your process group
When defining the scope of an alerting profile, which of the following is NOT an option?
Event filters
Management zone
Monitoring mode

While reviewing a security problem, you see the Davis Security Score (DSS) is Iower than the
Common Vulnerability Scoring System (CVSS). Why is this?
Davis has included information it knows about your evironment and has determined this vulnerability is not critical in your environment
This wouldn't happen as the DSS is never Iower than the CVSS, Davis will only increase the score when it determines the vulnerability is more critical in your environment
If there isn't code present in your environment that publicly exploits the vulnerability, the DSS
is always Iowered
When you mute a problem, Davis Iowers the DSS until the problem is unmuted

When monitoring applications in a virtualized environment, why is it important to monitor
the hypervisor and not just the virtual machines (guests)?
Even though applications running on guests are not affected by the hypervisor host hardware,
you need to monitor the hypervisor to get host metrics for the VM, such as CPU, Memory and
Disk usage.
Applications are affected by the hypervisor host hardware and virtualization issues such as steal time, which is not detectable on the guest VM
To monitor the virtual machines, you also need to deploy OneAgent to monitor the hypervisor
If you are deploying ActiveGates in a virtualized environment, they need OneAgent monitoring data from the hypervisor to ensure uptime and availability for OneAgent connections to the ActiveGate.
