CIS-DISCO sample questions

Question 1

During the debugging of a new Discovery pattern, an engineer observes that the identification section completes successfully, but the pattern fails immediately afterward with an error indicating 'Target CI not found' before entering the connection section. Review the diagram below representing the pattern logic flow. What is the most likely configuration error causing this specific failure?

Accepted Answer

The Identification Section failed to produce a valid unique identifier required to commit the CI to memory before the Connection Section runs.

Answer

The Connection Section was placed before the Identification Section in the pattern ordering.

Answer

The 'main' variable was cleared manually in the last step of the Identification Section.

Answer

The pattern is missing a 'Save' operation at the end of the Identification Section.

Question 2

A global enterprise has three data centers (Americas, EMEA, APAC). They require a Discovery architecture that ensures Discovery traffic remains local to each region to minimize WAN latency and adhere to data sovereignty laws. They also require high availability within each region. Which configuration best satisfies these requirements?

Accepted Answer

Configure three Load Balancing MID Server Clusters (one per region). Assign the appropriate regional Cluster to each regional Discovery Schedule.

Answer

Configure one global Failover Cluster containing all MID Servers and use Discovery Behaviors to filter traffic based on IP location.

Answer

Create three separate Discovery Schedules. Assign a specific MID Server from the respective region to each schedule.

Answer

Use a single Discovery Schedule with a Discovery Behavior that includes all MID Servers from all regions.

Question 3

While analyzing the ECC Queue, an administrator notices a 'No credentials would authenticate' error. In which phase of the Discovery PCIE cycle did this error occur, and what is the immediate consequence for the CI?

Accepted Answer

Classification phase; Discovery halts for that IP, and no CI is created or updated.

Answer

Exploration phase; The CI is created but relationships are missing.

Answer

Identification phase; A stub CI is created but lacks detailed attributes.

Answer

Port Scan phase; Discovery stops immediately for that IP.

Question 4

An implementation specialist needs to parse a version string from a raw data variable in Pattern Designer. The raw string format is `App_Name-v12.4.5-Build2024`. The requirement is to extract `12.4.5` into the `version` variable. Which Regular Expression (Regex) correctly captures this value?

Accepted Answer

v(\d+\.\d+\.\d+)

Answer

App_Name-(\w+)-Build

Answer

v[0-9]*

Answer

^.*-(.*)-.*$

Question 5

You are configuring the CMDB Identification and Reconciliation Engine (IRE). You have a requirement where CIs discovered by 'ServiceNow Discovery' should always overwrite attributes set by 'Manual Entry', but 'SCCM' imports should only update the 'Operating System' attribute if it is empty. Which feature should you configure to enforce these rules?

Accepted Answer

Reconciliation Definitions (Data Source Precedence)

Answer

CI Identifiers

Answer

Business Rules

Answer

Discovery Status

Question 6

A customer wants to run a quick discovery on a specific high-priority server to troubleshoot a configuration change. They do not want to create a formal Discovery Schedule. What is the most appropriate method to achieve this, and what input is required?

Accepted Answer

Use 'Quick Discovery'; requires the Target IP and a MID Server.

Answer

Use 'Pattern Designer' debug mode; requires the CI Class Name.

Answer

Use the 'Test Probe' feature; requires the specific Probe ID.

Answer

Create a new Discovery Schedule with 'Run Once'; requires a full IP Range.
