SERVICENOW-CIS-DISCOVERY Practice Test 5 — 10 Questions

Question 1

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

Accepted Answer

To retrieve data from an existing CMDB record.. The 'Lookup' step is used to find existing records in the CMDB that aren't the primary CI of the pattern.

Answer

To create a new CI.

Answer

To delete a CI.

Answer

To identify the primary CI.

Question 2

If you are troubleshooting a Discovery issue where the device is correctly classified but no data is being populated in the CMDB, which phase should you investigate first?

Accepted Answer

Exploration. Exploration is the phase where probes run to gather attributes to populate the CMDB.

Answer

Shazzam

Answer

Schedule

Answer

Classification

Answer

Identification

Question 3

When a discovery probe fails due to a timeout, what is the best way to increase the timeout value for that specific probe?

Accepted Answer

Update the probe's timeout parameter.. The 'Ecc_queue_timeout' parameter can be adjusted on the specific probe or sensor configuration.

Answer

Increase the Shazzam port wait time.

Answer

Modify the Discovery Schedule.

Answer

Change the global MID Server timeout property.

Question 4

You are performing Discovery and notice that the 'Discovery Status' shows 'Success', but the CI record was not updated. What is the most likely cause?

Accepted Answer

The Identification rules are preventing the update.. Identification rules (specifically Reconciliation rules) might be preventing updates to the CMDB.

Answer

The MID Server is down.

Answer

The credential had no access.

Answer

The Shazzam phase failed.

Question 5

When a Discovery scan completes, how can you view the status of all individual IP addresses scanned by that schedule?

Accepted Answer

View the Discovery Status record.. The 'Discovery Status' record provides a detailed list of all devices scanned, including errors and results.

Answer

Look at the ECC Queue directly.

Answer

Check the CMDB list.

Answer

Check the MID Server logs.

Question 6

Which of the following best describes the purpose of 'CMDB Data Manager'?

Accepted Answer

To automate the lifecycle management of CIs.. CMDB Data Manager is used for automating the lifecycle management of CIs, such as retiring or deleting them.

Answer

To map IP addresses to subnets.

Answer

To manage MID server credentials.

Answer

To generate reports on CI count.

Question 7

When the Identification and Reconciliation Engine (IRE) processes a payload, which THREE components determine if a CI is updated or created?

Accepted Answer

Data Source. The IRE relies on Identification Rules, Reconciliation Rules, and the payload content to make decisions.

Answer

MID Server configuration

Answer

Discovery Schedule

Question 8

You need to ensure that a specific attribute is NOT updated by any source except a manual update from a specific user group. How can this be done?

Accepted Answer

Set the Reconciliation rule for that attribute to only allow the 'Manual' data source.. Reconciliation rules allow you to specify data sources, but for non-Discovery sources, ACLs or Data Policies might be used; however, in terms of reconciliation, you can define a 'None' rule or manage it via source priority.

Answer

Change the class to 'Internal'.

Answer

Remove the attribute from the discovery pattern.

Answer

Create a business rule that runs after insert/update.

Question 9

What happens if a device is discovered that matches two different Classification records?

Accepted Answer

It uses the classifier with the highest priority.. Discovery uses priority values on classifiers to decide which one to apply when multiple match.

Answer

It errors out and stops discovery.

Answer

It asks the user to choose.

Answer

It applies both classifiers.

Question 10

During Discovery, a switch is identified, but its related interfaces are not appearing in the CMDB. What is the first thing you should check?

Accepted Answer

Identification Rule for the interface class. If the CI is identified but relationships are missing, the identification rule for the relationship (contained in the payload) is usually the cause.

Answer

MID Server capacity

Answer

Discovery Schedule timing

Answer

Discovery Error Log
