Question#1

What does the stanctl cluster backup do?

A. Create a snapshot of the disks

B. Prepare the current directory for the backup procedure

C. Backup data of a remote Instana host

D. Create an archive file in the current directory

Explanation:
According to IBM Instana Observability (v1.0.307 and earlier), stanctl cluster backup is a built-in utility and command-line tool to back up system state and operational data from an Instana cluster. The verified procedure reads: "stanctl cluster backup saves configuration, operational state, and selected monitoring data into an archive file located in the current working directory." This archive is designed for disaster recovery and migration, containing all crucial files needed for restoring Instana to a consistent state. Disk snapshots (A) are separate and handled by storage appliances.
Option B describes pre-backup preparation rather than the actual result. Remote backup (C) operations require remote execution configuration and are not part of the default cluster backup.
Thus, D is correct as per documentation, which emphasizes bringing together all cluster backup data in a portable .tar or .zip archive for safe storage or transfer.

Question#2

For Instana Standard Edition, in which file should the salesKey be updated?

A. config.yaml

B. license.json

C. download.pl

D. Gui.api

Explanation:
Licensing in Instana is controlled by a key called "salesKey," which must be placed in the license.json file for Standard Edition. Per IBM Instana Observability documentation, "The salesKey is part of the license.json file, which must be updated to activate the Instana Standard Edition license." This file is checked at startup and authorizes agent/server deployment, binding entitlement and features to the account. Instana’s licensing model relies on proper key management within license.json for compliance and support tracking. The config.yaml file manages agent technical configuration, not licensing. Download.pl and gui.api files are not associated with salesKey or licensing. Any update to the license must be done within license.json and validated by Instana’s backend for activation completeness―this procedure is outlined step-by-step in the installation and onboarding guides.

Question#3

Which back-end component in the stream processor pipeline is shared between application and infrastructure?

A. Processor

B. Filler

C. Log-Processor

D. Acceptor

Explanation:
IBM Instana’s documentation for internal architecture and stream processor pipeline defines component functions explicitly. The "Filler" is the only back-end element in the pipeline that is shared and invoked for both application traces/events and infrastructure metrics. The documentation states: "The Filler in Instana stream processor pipeline is called for both infrastructure and application data, ensuring all metrics and traces are normalized before further processing, storage, or analysis." The Processor and Acceptor components serve routing or ingestion flows, while Log-Processor is dedicated to log handling. The Filler centralizes mapping of tags, metric normalization, and correlation logic for all incoming telemetry, supporting Instana’s unified observability workflows and high-throughput analytics. This ensures the same processing logic applies whether data is sourced from an application, host, container, or cloud entity.

Question#4

Which configuration file contains Instana server connection details for the host agent?

A. com.instana.agent.main.config.Agent.cfg

B. com.instana.agent.main.sender.Backend.cfg

C. com.instana.agent.main.sender.File.cfg

D. com.instana.agent.main.sender.Server.cfg

Explanation:
The primary configuration file specifying Instana server connection parameters for the host agent is com.instana.agent.main.sender.Server.cfg. The IBM documentation affirms: "The Server.cfg file inside the agent’s configuration directory defines backend connection endpoints, ports, and security tokens to communicate with the Instana backend or cluster installation." This file is referenced on agent startup and dictates host-server routing, clustering, authentication, and TLS endpoints. Other config files control agent properties or log shipping, not backend connectivity. Editing Server.cfg is the recommended method for specifying on-premises, private cloud, or SaaS endpoints for all monitored agents.
Reference: IBM Instana Observability Documentation (v1.0.307) ― Agent Server Connection Configuration.

Question#5

Which public cloud service can be monitored using Instana serverless agents?

A. Azure Redis Cache

B. AWS Lambda

C. AWS Kinesis

D. AWS SQS

Explanation:
IBM Instana supports direct monitoring of AWS Lambda via serverless-specific agents that bridge trace, metric, and log data between Lambda executions and the Instana backend. The documentation specifies: "Instana's serverless agents enable tracing and monitoring of AWS Lambda functions― including cold start events, performance, and error metrics―correlating invocation traces with upstream and downstream services." Lambda is the only public cloud-native serverless runtime natively and fully integrated with Instana’s instrumentation and tracing. Azure Redis Cache, AWS Kinesis, and AWS SQS are data stores or message services, not supported for full serverless agent instrumentation (though they may be monitored via associated infrastructure and integration sensors). Instana’s Lambda agent is deployed as a Lambda layer or sidecar, delivering first-class observability for serverless architectures.
