DYNATRACE ASSOCIATE CERT ACTUAL FINAL
EXAM QUESTIONS AND ANSWERS SURE A+
✔✔What are the SPECIFIC anomaly detection metrics for database degradation? -
✔✔Action duration degradations, failed database connections and increases in failure
rate.
✔✔In what situations would you adjust the threshold levels that are automatically set by
Dynatrace? - ✔✔For level deviations above baseline performance are severe enough to
generate problem alerts.
✔✔Which two metrics are used to determine Host Memory Health? - ✔✔Memory used
and Page faults
✔✔What four metrics are used to determine Overall Host Health? - ✔✔CPU, Memory,
Disk, NIC, Network Services
✔✔How is network connectivity calculated (Especially with regards to TCP
connections)? - ✔✔Connectivity and local connectivity.
✔✔How is NIC health calculated? - ✔✔Traffic, packets, quality and connectivity
,✔✔Do you know why a Security Gateway (ActiveGate) is used? - ✔✔Access sealed
networks, story memory dumps, control load distribution of AWS monitoring, monitor
using an ActiveGate plugin, etc.
✔✔What is "Service Flow" and what can it be used for? - ✔✔Illustration of the sequence
of service calls that are triggered by each service request in an environment.
✔✔What entities can be tagged in Dynatrace? - ✔✔Hosts, process groups, services
and apps
✔✔What information does Dynatrace use to tag entities automatically? - ✔✔Rule based
tagging
Smartscape and topology API
Environment variables
Host autotag configuration file (For Hosts only)
✔✔Know the relationship between tags and metadata intimately. - ✔✔Tags are labels
or markers.Used to filter/find/designate sets of entities.
Metadata are key/value pairs.Used for defining extra information.
Detected during startup or discovery of a monitored entity.
✔✔Know the six different major types of events within Dynatrace and their order of
severity. - ✔✔Availability - indicates high-severity within your environment, such as
complete outages or unavailability of servers or processes.
Error - increased error rates or other error-related incidents that interfere with the
regular operation of environments.
Slowdown - decrease of performance in one of your operational services or applications
Resource - Indicates resource contention, many of which in link of name.
Custom Alerts - can be defined when a specific threshold notification on a selected
metric is required.
Info - alerts of issues that may not be detrimental, but should have notifications of
changes of occurrence. Indicate manually triggered events that don't result in the
creation of a new problem.
✔✔Know the difference between actions v. sessions and how they are related to each
other with regards to RUM. - ✔✔User Actions is an interaction with the web browser
that involves a call to a web server
Can be Page Load, XHR or a custom action
User Session is a group of user actions that are performed in your web application
during a limited period of time
✔✔What day of the week and how frequently are Dynatrace reports created? -
✔✔Every Sunday
, ✔✔Where can you see process and host crash events, respectively? - ✔✔In the events
section of each affected process and host page.
✔✔What are the different types of thresholds that can be set for
Databases? - ✔✔Response time degradations
Increases in failure rate
Failed database connections
✔✔What are the different types of thresholds that can be set for
Services? - ✔✔Detect response time degradations
Detect increases in failure rate
✔✔What are the different types of thresholds that can be set for
Processes? - ✔✔Actions duration degradation
Traffic drops
Traffic spikes
Increases in failure
✔✔How does Dynatrace monitor .NET applications? - ✔✔By placing trace statements
at strategic locations in your code for code tracing, performance metrics, error detection,
dependency tracking and more.
✔✔What is server side monitoring? - ✔✔Services that process requests like web
requests, web service calls, and messaging and can span multiple machines.
Monitoring all of the apps services, processes and infrastructure to pinpoint exactly how
each service contributes to the performance of your application.
✔✔How are databases uniquely identified by Dynatrace? - ✔✔Database name or
schema
Database vendor
And the IP address/port of the database
✔✔How are services identified? - ✔✔Web server name
Context root
Web application ID
✔✔What is the difference between a process and a process group? - ✔✔Process group
is the processes that perform the same functions across multiple hosts
Processes are the instances of computer programs and be containers that host
services.
✔✔Browser clickpath times - ✔✔5 minutes script timeout, 60 second event timeout
✔✔HTTP monitor times - ✔✔1, 2, 5, 10, 15, 30 or 60 minutes
