What the exam tests

What to know about Discovery Pattern Design

NAT questions usually test how private addresses are translated, when to use static NAT, dynamic NAT or PAT, and how inside/outside interfaces affect traffic flow.

Static NAT, dynamic NAT and PAT behaviour.

Inside local, inside global, outside local and outside global address meanings.

How NAT affects connectivity between private networks and public destinations.

How to troubleshoot NAT rules, ACL matches and interface direction.

Why learners struggle

Why Discovery Pattern Design questions are commonly missed

NAT questions are missed when learners confuse the four address types (inside local, inside global, outside local, outside global) or misapply the interface direction. A translation rule can look correct but still fail if the ACL, interface, or direction is wrong.

·Inside local vs inside global — inside local is the private source, inside global is the translated public address
·PAT overloads — many sources share one public IP using unique port numbers
·Interface direction — ip nat inside and ip nat outside must be on the correct interfaces
·Static NAT vs dynamic NAT vs PAT — each serves a different use case
·The NAT ACL identifies traffic to translate, not traffic to permit or deny
·A missing translation can look like a routing problem if the interfaces are misconfigured

Watch out for

Common Discovery Pattern Design exam traps

▸PAT allows many inside hosts to share one public address by using port numbers.
▸NAT rules depend on correct inside and outside interface configuration.
▸The ACL used for NAT identifies traffic to translate; it is not always a security filtering ACL.
▸Static NAT maps one private address to one public address, while PAT overloads translations.

When debugging a pattern that fails to parse a JSON response, which tool in the Pattern Designer provides the most granular view of the variable state after a 'Parse JSON' step?

Trap 1: Pattern Log

Logs show execution flow, not variable memory state.

Trap 2: The CMDB CI Class Manager

Class Manager manages attributes, not pattern execution state.

Trap 3: The Discovery Status record

Status records provide high-level error summaries.

Discovery Pattern Design questions

When debugging a pattern that fails to parse a JSON response, which tool in the Pattern Designer provides the most granular view of the variable state after a 'Parse JSON' step?

You are creating a new Discovery pattern and need to extract data from a command output where lines are separated by a consistent delimiter. Which parsing strategy should you use to map these specific values to table attributes?

You need to add a new CI type to an existing horizontal pattern. Which step must be performed in the Pattern Designer to ensure the CI is linked to the parent process?

Which THREE of the following are valid ways to identify a CI in a pattern?

In the Pattern Designer, you need to set a CI attribute only if a specific command output returns a value. Which operation type should be used to define this conditional logic?

When debugging a pattern that fails during the identification phase, which TWO areas should you inspect in the Pattern Designer?

During pattern debugging, you notice that a specific step is failing to run on a MID Server. You want to see the exact input and output of that step. Where should you look?

You are modifying a pattern and need to extract a specific attribute from a JSON response returned by an API. Which step type is most appropriate for this task?

In the Pattern Designer, what is the primary purpose of the 'Connection' section?

You are creating a pattern to capture a version number from a command line output. The output is 'Version: 1.2.3.4'. Which parsing strategy is most efficient for this specific string?

Which action allows you to test a pattern against a specific Discovery status record without running a full Discovery scan?

In a horizontal pattern, you have an Identification section that fails to match a CI. What is the most likely cause if the 'Identification' step has correct attributes?

When designing a pattern to identify a custom application, which section is responsible for populating the CI attributes?

When configuring a 'Set Parameter' step, where is the value retrieved from if you select 'Variable'?

When dealing with a nested XML response from an API, which parsing method should be used to drill down into a specific child node?

What happens if a pattern execution encounters an error in a step that is marked as 'Continue on error'?

Which of the following is the correct order of operations in a horizontal pattern?

What is the benefit of using an Extension section in a pattern?

When should you use the 'Lookup' step in a pattern?

Which UI tool is used to visualize the pattern execution flow?
