DYNATRACE PROFESSIONAL CERTIFICATION

DYNATRACE PROFESSIONAL CERTIFICATION WRITTEN EXAM QUESTIONS AND ANSWERS 2023 FINAL UPDATE GRADED A+ What are the 4 parts included in the 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 ANSWERSEnvironment 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 ANSWERSTechnology 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 ANSWERSDefine important metrics to be displayed in technology overview page. What is the favicon property in the definition? - CORRECT ANSWERSAllows 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- What is pgmetrics in for ActiveGate plugins? - CORRECT ANSWERSSection 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 (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)
