DYNATRACE PRO COMPREHENSIVE EXAM QUESTIONS
AND SOLUTIONS RATED A+
✔✔How do you manually generate problems for your ActiveGate plugins? - ✔✔Python
API - raise performance, availability, error, and resource contention problems
✔✔Does Dynatrace automatically distribute plugins between Dynatrace server and
ActiveGates? - ✔✔No, you need to deploy them on ActiveGate and upload them to
server.
✔✔In general, what is the point of plugins.json (ActiveGate plugins)? - ✔✔Define how
data is presented in the Dynatrace UI.
✔✔In general, what is the point of Python files for ActiveGate plugins? - ✔✔Define
additional events, create custom properties.
✔✔How many Cluster Management Consoles are there per cluster? - ✔✔One per
cluster.
✔✔What is each managed cluster associated with? - ✔✔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? -
✔✔Dynatrace Server, Cassandra, Elasticsearch, Embedded ActiveGate, NGINX
✔✔What can you do with CMC? - ✔✔Create user accounts and groups, add new
cluster nodes, add new monitoring environments.
✔✔How many nodes does Dynatrace recommend per cluster? - ✔✔At least 3 - data is
replicated across nodes
✔✔What percentage of managed cluster nodes does Dynatrace need to be running? -
✔✔Majority (50%+)
✔✔What does Dynatrace recommend for latency between managed cluster nodes? -
✔✔10ms or less
✔✔Is transaction data (call stacks, database statements, code-level visibility etc.)
replicated across managed cluster nodes? - ✔✔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? - ✔✔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? - ✔✔At least 3 data
centers (1 can fail)
✔✔Why does Dynatrace recommend that each managed cluster node be deployed on a
separate physical disk? - ✔✔To prevent loss of monitoring data.
✔✔Why does Dynatrace recommend deploying managed cluster nodes on systems
with the same hardware characteristics? - ✔✔To minimize performance loss
✔✔What should you keep in mind when building your manged cluster? - ✔✔Build
cluster with additional capacity and possible node failure in mind.
✔✔What happens when a managed cluster node fails? - ✔✔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? -
✔✔If you want your managed cluster to only be accessible internally.
✔✔Why would you use Dynatrace Managed deployment scenario 2: Pure Dynatrace
Managed setup? - ✔✔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? - ✔✔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? - ✔✔Yes
✔✔In Dynatrace Managed deployment scenario 1: basic setup, what is each
communication channel secured with? - ✔✔TLS (Transport layer security)
✔✔Is a Cluster ActiveGate required for Dynatrace Managed deployment scenario 2:
Pure Dynatrace Managed setup? - ✔✔Yes. It needs a publicly available IP address, a
domain name with a valid SSL certificate, and the domain must be different from web UI
domain.
, ✔✔How many Cluster ActiveGates are recommended for high-load production-ready
installations with external hosts, apps, sessions and synthetic monitoring? - ✔✔2
Cluster ActiveGates are recommended with the same domain name and certificate
✔✔What are the steps to take to use an Environment ActiveGate and a Cluster
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.
✔✔Is CMC web UI traffic accessed using HTTP or HTTPS? - ✔✔HTTPS
✔✔Is a TLS certificate required to use CMC? - ✔✔Yes
✔✔What is the default subdomain of a managed cluster? - ✔✔*.dynatrace-
managed.com
✔✔Do managed clusters automatically have an SSL certificate? - ✔✔Yes - from Let's
Encrypt
✔✔Do Cluster ActiveGates support proxying of Web UI traffic? - ✔✔No
✔✔How should you prepare to horizontally scale your managed cluster? - ✔✔Adding
more nodes
✔✔How many managed cluster nodes does Dynatrace support for managed versions
1.168 and higher? - ✔✔15 cluster nodes
✔✔How many managed cluster nodes does Dynatrace support for managed versions
1.167 and lower? - ✔✔6 cluster nodes
✔✔How should you prepare to vertically scale your managed cluster? - ✔✔Provisioning
more RAM/CPU per node, resize disk volume for storage size as required.
✔✔What resources must be made exclusively available for Dynatrace in a managed
cluster node? - ✔✔CPU and RAM
✔✔Can managed cluster node CPUs have power saving mode enabled? - ✔✔No,
power saving mode must be disabled
✔✔What is the minimum CPU clock speed of a manged cluster node? - ✔✔2GHz
