Answer

In the ServiceNow Credential store.

Answer

Via a MID Server Script File.

Answer

In the 'Proxy' related list on the MID Server record.

Question 4

A customer needs to restrict a MID Server to only perform discovery on specific IP ranges. Which mechanism should be used to accomplish this?

Accepted Answer

Define 'MID Server IP Ranges' related list on the MID Server record.. MID Server IP Ranges are used to define the boundaries of what a specific MID Server is allowed to scan.

Answer

Set the 'Scan Limitation' property on the MID Server configuration file.

Answer

Use the 'Discovery Schedule' Exclude IP list only.

Answer

Apply a Business Rule to the ECC Queue.

In the 'MID Server Properties' module.

Answer

In the config.xml file.

Question 6

When upgrading a MID Server, what is the best practice for a manual upgrade process?

Accepted Answer

Use the 'Upgrade' UI action on the MID Server record.. The recommended practice is to trigger the upgrade from the MID Server record in the instance to ensure synchronization.

Answer

Delete the entire agent folder and reinstall.

Answer

Manually replace the agent JAR files.

Answer

Change the version in config.xml.

Question 7

You are deploying a MID Server behind a strict firewall. To ensure the MID Server can communicate with the ServiceNow instance without opening unsolicited inbound ports, which configuration is required?

Accepted Answer

Ensure the firewall allows outbound HTTPS traffic from the MID Server to the instance.. MID Servers communicate via outbound HTTPS (443) requests to the instance, meaning no inbound ports need to be opened on the firewall.

Answer

Set the MID Server listener port to 8443 on the local firewall.

Answer

Configure the instance to use an inbound static IP for the MID Server.

Answer

Enable the 'Inbound Proxy' setting in the MID Server configuration file.

Question 8

A MID Server Cluster is configured with two nodes. One node goes down. How does the MID Server Cluster handle the failover?

Accepted Answer

The cluster automatically shifts the workload to the healthy node in the cluster.. MID Server clusters automatically distribute work, and if one node fails, the cluster manager ensures tasks are re-queued or picked up by the remaining node.

Answer

The cluster requires a manual restart of the remaining node to resume work.

Answer

The instance marks the MID Server as 'Down' and stops all processing for the entire cluster.

Answer

All tasks are automatically lost and must be manually re-run.

Question 9

When using multiple MID Servers for load balancing, what is the best way to group them?

Accepted Answer

Create a MID Server Cluster.. MID Server Clusters allow you to group MID Servers for load balancing and failover.

Answer

Use the 'MID Load Balancer' application.

Answer

Update the config.xml on each server to point to the same instance node.

Answer

Assign them the same IP range.

Question 10

Which TWO of the following are true regarding MID Server startup parameters in the config.xml?

Accepted Answer

Answer

These settings override any properties set in the MID Server record in the instance.

Answer

They are automatically synced with the instance properties every hour.
