100% Errorless Answers.
Dynatrace SaaS vs Managed correct answers Dynatrace SaaS is a cloud-hosted service where
Dynatrace operates the cluster, while Dynatrace Managed is a self-hosted deployment where you
install and run the Dynatrace cluster on your own infrastructure. SaaS requires internet access to
Dynatrace cloud, whereas Managed runs on-premises (or in your cloud) with your control over
data and upgrades.
Dynatrace OneAgent correct answers A host-based agent that is installed on each monitored
host. OneAgent automatically instruments processes, collects metrics (CPU, memory, network,
etc.), traces transactions end-to-end (PurePath), and reports data to the Dynatrace cluster
(directly or via an ActiveGate).
Dynatrace ActiveGate correct answers A gateway component that acts as a secure proxy between
OneAgents and the Dynatrace cluster. ActiveGates route OneAgent traffic (especially from
isolated networks) to the cluster, and also execute special tasks such as cloud monitoring,
Synthetic monitor execution, and z/OS monitoring.
Environment ActiveGate vs Cluster ActiveGate correct answers Environment ActiveGates are
installed by customers to serve a specific environment (tenant) and handle OneAgent routing,
synthetic, and integration tasks. Cluster ActiveGates are built-in to Dynatrace Managed cluster
nodes and handle cluster-level communication. In Dynatrace SaaS you only use Environment
ActiveGates.
Dynatrace cluster node (Managed) correct answers A Dynatrace Managed cluster node is a
server that runs the Dynatrace cluster software, including components for processing, storing,
and querying monitoring data. Each node includes services and storage and an embedded
ActiveGate.
Cluster architecture and replication correct answers Dynatrace Managed clusters require at least
3 nodes for production to ensure high availability. Data is replicated across nodes so that if one
node fails, data remains available. All cluster nodes are active and share the load.
Mission Control (Dynatrace Managed) correct answers A Dynatrace cloud service that connects
with Dynatrace Managed clusters to provide license management, usage reporting, health
monitoring, and remote support. If connectivity is lost, license overages are disabled after 14
days.
Data encryption in transit correct answers All communication between OneAgent, ActiveGate,
and Dynatrace cluster is encrypted via TLS.
OneAgent to ActiveGate connection port correct answers OneAgent connects to an Environment
ActiveGate on port 9999 (HTTPS).
, ActiveGate to Cluster connection ports correct answers Environment ActiveGates communicate
with the Dynatrace cluster typically on port 443 or 8443.
Network zones correct answers A Network Zone is a logical label that helps control and optimize
OneAgent traffic routing by assigning it to nearby ActiveGates.
Multi-environment support correct answers Dynatrace Managed allows multiple monitoring
environments (tenants) on one cluster, each logically separated with its own data.
Embedded ActiveGate (Managed cluster) correct answers Each Dynatrace Managed cluster node
includes an embedded ActiveGate for cluster-level communication.
Update cadence (SaaS vs Managed) correct answers SaaS clusters are updated by Dynatrace
automatically, while Managed clusters are updated manually by the administrator.
OneAgent update mechanism correct answers OneAgents can be upgraded centrally by the
cluster, automatically or manually depending on settings.
ActiveGate update mechanism correct answers Environment ActiveGates support auto-update
when configured or can be updated manually.
High availability for ActiveGates correct answers Multiple ActiveGates can be installed in the
same zone for failover and load balancing.
Scaling Dynatrace Managed correct answers Add nodes with similar specs or increase node
resources to scale Dynatrace Managed clusters.
Data storage (Dynatrace cluster) correct answers Dynatrace cluster nodes use Cassandra for
metrics and Elasticsearch for events/traces.
SaaS data centers vs Managed correct answers In SaaS, data is stored in Dynatrace cloud
regions. In Managed, data resides on your own nodes.
Mission Control connectivity requirement correct answers Managed clusters must connect to
Mission Control periodically unless using offline mode.
OneAgent performance overhead correct answers Typical CPU usage is 1-5% and memory use is
modest, making OneAgent lightweight.
oneagentctl correct answers Command-line tool used to configure OneAgent settings like proxy,
network zone, tenant, or restart features.
OneAgent installation methods correct answers Install via shell script, MSI installer, or
deployment tools like Chef, Puppet, or Ansible.
