CSA System Installation and Configuration 2 — Questions and Answers
Question 1: Which ServiceNow installation method allows multiple application nodes to share a single database instance?
- Clustered deployment (Correct answer)
- Standalone deployment
- MID Server deployment
- High-availability deployment
Correct answer: Clustered deployment
Clustered deployment connects multiple application nodes to one database, enabling load balancing and redundancy.
Question 2: During a ServiceNow upgrade, what is the recommended action before applying a new release?
- Back up the database and clone to a sub-production instance first (Correct answer)
- Apply the upgrade directly to production
- Disable all active business rules
- Delete all scheduled jobs temporarily
Correct answer: Back up the database and clone to a sub-production instance first
Best practice requires backing up the database and testing the upgrade on a sub-production instance before applying to production.
Question 3: What is the purpose of the 'glide.db.pool.connections' system property in ServiceNow?
- It controls the number of database connections available to the application (Correct answer)
- It sets the number of active users allowed
- It defines the memory allocated to the JVM
- It configures the cache expiration interval
Correct answer: It controls the number of database connections available to the application
The glide.db.pool.connections property determines how many simultaneous database connections the instance can maintain.
Question 4: Which file is used to configure JVM heap memory settings in a ServiceNow on-premise deployment?
- wrapper.conf (Correct answer)
- glide.properties
- nodes.properties
- system.properties
Correct answer: wrapper.conf
The wrapper.conf file contains JVM startup parameters including heap memory size settings for ServiceNow nodes.
Question 5: In ServiceNow, what does the MID Server facilitate?
- Communication between the ServiceNow instance and resources on a local network (Correct answer)
- Direct database access for reporting
- User authentication via LDAP only
- Load balancing between application nodes
Correct answer: Communication between the ServiceNow instance and resources on a local network
A MID Server acts as a proxy to enable the ServiceNow cloud instance to communicate securely with on-premise network resources.
Question 6: What must be configured on a MID Server to allow it to validate against a ServiceNow instance?
- A service account username and password with the mid_server role (Correct answer)
- An admin API key
- An OAuth 2.0 client secret
- A mutual TLS certificate pair
Correct answer: A service account username and password with the mid_server role
The MID Server config.xml requires credentials for a ServiceNow user account that has the mid_server role assigned.
Question 7: Which ServiceNow table stores configuration parameters that control instance-wide system behavior?
- sys_properties (Correct answer)
- sys_config
- sys_params
- sys_metadata
Correct answer: sys_properties
The sys_properties table holds system properties (name-value pairs) that govern global instance configuration.
