DYNATRACE PROFESSIONAL CERTIFICATION WRITTEN EXAM
QUESTIONS AND ANSWERS 2023 FINAL UPDATE GRADED A+
What are the 4 parts included in the plugin.json definition for ActiveGate plugins? -
CORRECT ANSWERS-Metadata, UI, Metrics, Configuration
How are ActiveGate plugins licensed? - CORRECT ANSWERS-The plugin SDK is free.
Dynatrace partners can develop plugin for you, will depend on contract. Whatever
custom metrics are used will be charged.
How frequently do ActiveGate plugins execute? - CORRECT ANSWERS-Once per
minute
Can you run multiple endpoints in a single ActiveGate plugin module? - CORRECT
ANSWERS-Yes
What kind of ActiveGate executes ActiveGate plugins? - CORRECT ANSWERS-
Environment ActiveGate
Can you execute ActiveGate plugins using an Environment ActiveGate that's configured
for multi-environment support? - CORRECT ANSWERS-No
Where can you view results from plugin-monitoring? - CORRECT ANSWERS-
Technology overview page
What is a "device group"? - CORRECT ANSWERS-A technology tile that derives its
data from an ActiveGate plugin.
Why would you set up "key metrics" for an ActiveGate plugin? - CORRECT ANSWERS-
Define important metrics to be displayed in technology overview page.
What is the favicon property in the plugins.json definition? - CORRECT ANSWERS-
Allows you to define your own custom icon for device groups!
What can device groups represent? - CORRECT ANSWERS-Clusters, regions, groups
of servers, etc.
What is a custom device group entity? - CORRECT ANSWERS-Bind metrics and
properties to monitor device group metrics
How do you define the type and look of charts of ActiveGate plugins? - CORRECT
ANSWERS-plugin.json
,What is pgmetrics in plugins.json for ActiveGate plugins? - CORRECT ANSWERS-
Section that allows you to define custom device metrics.
Does Dynatrace AI baseline the metrics of your custom devices? - CORRECT
ANSWERS-Yes!
How does Dynatrace create problems from custom devices (ActiveGate plugin)? -
CORRECT ANSWERS-Metric threshold violation in JSON definition. (Automatically
sends events, not problems)
How do you manually generate problems for your ActiveGate plugins? - CORRECT
ANSWERS-Python API - raise performance, availability, error, and resource contention
problems
Does Dynatrace automatically distribute plugins between Dynatrace server and
ActiveGates? - CORRECT ANSWERS-No, you need to deploy them on ActiveGate and
upload them to server.
In general, what is the point of plugins.json (ActiveGate plugins)? - CORRECT
ANSWERS-Define how data is presented in the Dynatrace UI.
In general, what is the point of Python files for ActiveGate plugins? - CORRECT
ANSWERS-Define additional events, create custom properties.
How many Cluster Management Consoles are there per cluster? - CORRECT
ANSWERS-One per cluster.
What is each managed cluster associated with? - CORRECT ANSWERS-One or more
nodes (with Dynatrace server instances), one or more monitored environments (with
OneAgent), one cluster management console.
What are the components included in the Dynatrace Managed installer? - CORRECT
ANSWERS-Dynatrace Server, Cassandra, Elasticsearch, Embedded ActiveGate,
NGINX
What can you do with CMC? - CORRECT ANSWERS-Create user accounts and
groups, add new cluster nodes, add new monitoring environments.
How many nodes does Dynatrace recommend per cluster? - CORRECT ANSWERS-At
least 3 - data is replicated across nodes
What percentage of managed cluster nodes does Dynatrace need to be running? -
CORRECT ANSWERS-Majority (50%+)
What does Dynatrace recommend for latency between managed cluster nodes? -
CORRECT ANSWERS-10ms or less
, Is transaction data (call stacks, database statements, code-level visibility etc.) replicated
across managed cluster nodes? - CORRECT ANSWERS-No - evenly distributed across
all nodes
If you're distributing managed cluster nodes across separate data centers, what is the
max amount of nodes that Dynatrace recommends per data center? - CORRECT
ANSWERS-No more than 2 nodes per data center
If you're distributing managed cluster nodes across separate data centers, what is the
min amount of data centers that Dynatrace recommends? - CORRECT ANSWERS-At
least 3 data centers (1 can fail)
Why does Dynatrace recommend that each managed cluster node be deployed on a
separate physical disk? - CORRECT ANSWERS-To prevent loss of monitoring data.
Why does Dynatrace recommend deploying managed cluster nodes on systems with
the same hardware characteristics? - CORRECT ANSWERS-To minimize performance
loss
What should you keep in mind when building your manged cluster? - CORRECT
ANSWERS-Build cluster with additional capacity and possible node failure in mind.
What happens when a managed cluster node fails? - CORRECT ANSWERS-NGINX
automatically load balances and redirects all OneAgent traffic to the remaining working
nodes.
Why would you use Dynatrace Managed deployment scenario 1: Basic setup? -
CORRECT ANSWERS-If you want your managed cluster to only be accessible
internally.
Why would you use Dynatrace Managed deployment scenario 2: Pure Dynatrace
Managed setup? - CORRECT ANSWERS-If you want to enable DEM services and
communication from external sources.
Why would you use Dynatrace Managed deployment scenario 3: integration with
existing IT landscape? - CORRECT ANSWERS-When customer already has
environment with load balancers and proxies in place.
In Dynatrace Managed deployment scenario 1: basic setup, is remote access to Mission
Control enabled? - CORRECT ANSWERS-Yes
In Dynatrace Managed deployment scenario 1: basic setup, what is each
communication channel secured with? - CORRECT ANSWERS-TLS (Transport layer
security)
