Question 1

Which data source on the analytics page shows traces?

Accepted Answer

B

Explanation: In IBM Instana Observability, the Analytics page is a powerful tool for deep-diving into performance data. Traces, which represent the end-to-end journey of a request through a distributed system, are the fundamental data unit for Application Performance Monitoring (APM). This APM data is categorized and analyzed under the Applications data source. Within the Analytics view, users select an Application Perspective to filter, group, and investigate the associated traces and calls to diagnose latency, errors, and other performance bottlenecks.

Question 2

Which statement best describes Beelnstana?

Accepted Answer

C

Explanation: Beelnstana is the official name for the Kubernetes operator used to deploy and manage the self-hosted (on-premises) Instana backend. A key characteristic of this deployment is its architecture, which relies on a cluster of high-performance, distributed data stores, such as Cassandra and ClickHouse. The Beelnstana operator is responsible for orchestrating the deployment of the entire Instana backend, which includes these essential data store components required to process and store large volumes of observability data effectively.

Question 3

At which level can AWS agent polling intervals for CloudWatch API be configured?

Accepted Answer

B

Explanation: The configuration of the AWS agent's polling interval for the CloudWatch API is managed at the agent instance level. In IBM's monitoring solutions, such as IBM Cloud Application Performance Management (APM) or its successors, the standard practice for monitoring multiple AWS regions is to create and configure a separate agent instance for each region. Each of these instances has its own configuration file where parameters like the CloudWatch polling interval can be set independently. Therefore, the polling interval can be effectively configured at the Region level.

Question 4

In Instana Standard Edition, which statement is true about the migration from a single-node deployment to a multi-node deployment?

Accepted Answer

A

Explanation: According to the official IBM Instana documentation, the migration path from a single-node to a multi-node deployment is only supported for "production" type installations. The "demo" installation type, which is intended for trial or non-production environments and uses an embedded database, is explicitly excluded from this migration path. This limitation is in place because the architecture and data storage of a demo installation are not suitable for scaling into a distributed, multi-node production environment.

Question 5

Which action triggers an event when a Synthetic PoP is uninstalled?

Accepted Answer

C

Explanation: IBM Instana provides a set of pre-configured, built-in events to monitor the health of its components. The "Synthetic pop status" is a specific built-in event designed to track the state of a Synthetic Point of Presence (PoP). When a PoP is uninstalled, it stops sending heartbeats to the Instana backend. The system automatically detects this lack of communication and triggers the "Synthetic pop status" event to report the PoP as offline. This process is fully automated and requires no manual intervention or custom configuration.

Question 6

What is a valid method for an administrator to delete the 2FA settings of a user?

Accepted Answer

B

Explanation: The standard and officially documented procedure for an administrator to manage a user's Two-Factor Authentication (2FA) settings is through the Instana user interface. The administrator must navigate to the 'Settings' area, select the 'Users' management page, choose the specific user whose 2FA needs to be reset, and then use the dedicated option to delete or reset their 2FA configuration. This ensures the action is performed safely within the application's intended workflow.

Question 7

What happens when multiple agent configuration files are created and put alongside the main configuration.yaml?

Accepted Answer

C

Explanation: The Instana agent is designed to support a modular configuration by using multiple YAML files. The agent processes these files in a specific, deterministic order. It always reads the main configuration.yaml file first. After that, it reads all other .yaml files located in the same directory in alphabetical order. This sequential loading process effectively merges the settings. If a configuration key is defined in more than one file, the value from the last file read will be the one that is used.

Question 8

What prevents Ansible actions from manual deletion within Instana?

Accepted Answer

D

Explanation: Instana provides several out-of-the-box integrations and configurations, which are referred to as "Default Actions." These actions are built-in to ensure that core automation and integration capabilities are always available and consistently configured. To maintain system integrity and prevent accidental removal of essential functionality, these default actions are protected and cannot be manually edited or deleted by users through the Instana UI. This is a common design pattern in enterprise software to safeguard baseline configurations.

Question 9

What is an agile set of focused security and privacy practices that are used by Instana?

Accepted Answer

A

Explanation: IBM Instana Observability is developed and managed using the IBM Security and Privacy by Design (SPbD) process. This methodology is explicitly defined as an agile set of focused security and privacy practices. It integrates threat modeling, privacy assessments, static and dynamic security testing, and vulnerability management directly into the development lifecycle. This ensures that security and privacy are fundamental components from the initial design phase through deployment and operations, rather than being addressed as an afterthought.

Question 10

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

Accepted Answer

B

Explanation: The Instana host agent uses an OSGi-based framework, and its configuration is modularized into several files within the /etc/instana/ directory. The file com.instana.agent.main.sender.Backend.cfg specifically contains the runtime configuration for the agent's connection to the Instana backend (server). This includes the endpoint host and port, which the agent uses to send collected metrics and traces. These settings are typically populated from higher-level configurations like environment variables or the configuration.yaml file upon agent startup.

Question 11

Which statement is true about webhook URL authentication?

Accepted Answer

A

Explanation: IBM Cloud Pak for AIOps supports multiple authentication methods for incoming webhook connections, including basic authentication. One of the documented methods for implementing basic authentication is to embed the credentials directly within the webhook URL. The supported format is https:// : @ : / . This allows external systems that support this URL format to securely connect and send data to the AIOps event manager. This method is explicitly provided as a configuration option when setting up a generic webhook integration.

Question 12

Which two steps are performed in preparation for migrating from a self-hosted single-node deployment to a multi-node deployment of Instana?

Accepted Answer

C, E

Explanation: Migrating from a single-node to a multi-node Instana deployment requires preparing new hosts to function as a cohesive, distributed cluster. A critical preparation step is tuning the operating system on the new hosts by checking and adjusting kernel parameters, such as vm.maxmapcount, which is essential for the stability and performance of components like Elasticsearch. Furthermore, establishing reliable and secure network communication between all nodes is fundamental for a multi-node architecture. This is typically achieved by configuring private IP addresses to ensure the hosts can reach each other for data replication, coordination, and internal API calls.

Question 13

What are the two SLI types Instana supports while configuring the service level objectives?

Accepted Answer

C, D

Explanation: According to the official IBM Instana documentation, Instana supports two distinct types of Service Level Indicators (SLIs) when configuring Service Level Objectives (SLOs). These are: 1. Time-based SLIs: This type measures the performance of a service over time. It calculates the ratio of "good" time (when the service meets the defined performance criteria) to the total evaluation time. 2. Event-based SLIs: This type measures the performance based on a count of discrete events, typically calls or traces. It calculates the ratio of "good" events (e.g., successful requests, fast responses) to the total number of events. Therefore, "Time based" and "Event count based" are the two supported SLI types.

Question 14

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

Accepted Answer

B

Explanation: Instana provides specific monitoring for serverless compute platforms like AWS Lambda. This is accomplished by using an Instana Lambda Layer or by including an Instana library directly in the function's code. This component acts as the "serverless agent," enabling in-process tracing and performance metric collection for the function's executions. This method provides deep visibility into the serverless application's performance, which is distinct from the metric-polling approach used for other managed services.

Question 15

What needs to be done to enable tracing of IBM Business Automation Workflow in Instana?

Accepted Answer

C

Explanation: Business-Automation-Workflow (BAW) tracing is already shipped with the Instana agent; it is simply disabled by default. To start capturing BAW traces, you open the Instana Web UI, navigate to Settings ➔ Configuration ➔ Automatic Unbounded Service Tracing ➔ Technologies (or Tracing ➔ Technologies in older releases) and switch on “IBM Business Automation Workflow.” No file edits, extra binaries or dashboards are required—the sensor is activated from the UI and Instana immediately begins collecting and presenting BAW spans.
