SERVICENOW-CIS-DISCOVERY Discovery Configuration Practice Test 3 — 15 Questions

Question 1

When troubleshooting a specific device, how can you see exactly what was returned by the probes?

Accepted Answer

View the ECC Queue records related to the status.. The Discovery Status record allows you to drill down into the 'Devices' and 'ECC Queue' to see the raw input data.

Answer

Run the discovery again.

Answer

Check the MID Server logs.

Answer

View the CI record.

Question 2

What is the maximum number of times a Discovery Schedule can run?

Accepted Answer

Unlimited, based on system configuration.. Discovery schedules can be configured to run as often as required by the system capability.

Answer

100 times total.

Answer

Once per day.

Answer

Only once.

Question 3

What does the 'Discovery Status' field 'Completed' mean?

Accepted Answer

The discovery process has finished executing.. It indicates that all phases of the discovery process for that specific status record have finished.

Answer

No errors occurred.

Answer

The CMDB is now up-to-date.

Answer

All devices were successfully updated.

Question 4

A customer needs to discover devices across a firewall. What is the standard configuration to allow this?

Accepted Answer

Place a MID Server inside the network segment of the target devices.. The MID Server must be placed in a zone that can communicate with the target devices, and the firewall must allow the specific ports required by the probes.

Answer

Open all ports on the firewall.

Answer

Use a VPN connection on the instance.

Answer

Enable 'External Discovery' in the instance.

Question 5

Which of the following is a valid method to trigger a Discovery scan manually?

Accepted Answer

Click 'Discover Now' on the Discovery Schedule record.. You can click the 'Discover Now' button on a Discovery Schedule record.

Answer

Edit the ECC Queue.

Answer

Restart the MID Server.

Answer

Run a Business Rule.

Question 6

What is the purpose of an 'IP Service' in Discovery?

Accepted Answer

To define a set of ports and protocols for scanning.. IP Services group ports and protocols together for use in port scanning, making it easier to define what to scan.

Answer

To assign a MID Server.

Answer

To define the IP range.

Answer

To provide credentials.

Question 7

When a discovery scan is running very slowly, which configuration adjustment might improve performance?

Accepted Answer

Increasing the number of concurrent tasks on the MID Server.. Adjusting the 'Max number of concurrent discovery tasks' on the MID Server can improve throughput.

Answer

Adding more IP ranges to the schedule.

Answer

Deleting all existing CI records.

Answer

Changing the Discovery schedule to 'Weekly'.

Question 8

What is the consequence of deleting a Discovery Schedule?

Accepted Answer

It prevents future automated runs of that schedule.. Deleting the schedule stops all future automated discovery scans associated with that schedule.

Answer

It breaks the MID Server.

Answer

It forces a full re-discovery.

Answer

It deletes all previously discovered CIs.

Question 9

Which field on the Discovery Schedule allows you to restrict the discovery to specific device types?

Accepted Answer

Behavior. The 'Behavior' field is used to select which probes/patterns run, effectively limiting what is discovered.

Answer

Schedule

Answer

MID Server

Answer

IP Range

Question 10

What is the primary way to check if a MID Server is communicating correctly with the ServiceNow instance?

Accepted Answer

Check the 'MID Server' list status.. The MID Server status on the 'MID Server' list view shows 'Up' if it is connected.

Answer

Check the Discovery log.

Answer

Ping the MID Server from your computer.

Answer

Check the CMDB.

Question 11

If you need to ensure that a Discovery scan does not impact network traffic, what is a recommended best practice?

Accepted Answer

Distribute discovery scans across multiple schedules and MID servers.. Staggering discovery schedules and using IP ranges to distribute the load across time and MID servers is the standard practice.

Answer

Set the discovery to run at night.

Answer

Disable the Shazzam phase.

Answer

Limit the scan to one IP per hour.

Question 12

What is the purpose of the 'Identification' phase in Discovery?

Accepted Answer

To match the discovered CI to an existing one in the CMDB.. The Identification phase reconciles discovered data with existing CIs in the CMDB using defined Identification Rules.

Answer

To find the IP address of the device.

Answer

To determine what the device is.

Answer

To gather hardware details.

Question 13

A new device type is not being discovered correctly. Where should you look to ensure the classification process is prepared to handle it?

Accepted Answer

The Discovery Classifiers table.. The 'Discovery Classifiers' table contains the rules used to identify and classify devices.

Answer

The Credential Alias list.

Answer

The IP Range definitions.

Answer

The MID Server configuration.

Question 14

Which of these is a valid way to organize discovery when dealing with a very large network?

Accepted Answer

Use multiple schedules and MID servers to segment the workload.. Using multiple discovery schedules and assigning them to different MID servers is the standard architectural approach.

Answer

Disable the identification phase.

Answer

Use a single schedule for everything.

Answer

Run everything at once.

Question 15

What does 'Discovery' in ServiceNow primarily populate?

Accepted Answer

The CMDB.. Discovery is designed to populate the Configuration Management Database (CMDB).

Answer

The knowledge base.

Answer

The user database.

Answer

The incident table.
