ServiceNow CIS-HR free question 2 / 10 · Domain 1: Describe and use the ServiceNow HR System Architecture
A developer creates a scoped application and keeps a 32-character application name as its application ID. What does the Namespace identifier page say happens?
- The ID is accepted, and the developer can shorten the identifier on the artifacts later
- The customer prefix is shortened to two characters to make room for the long ID
- The ID is accepted, but the system truncates it when it builds the identifier
- The ID is rejected, because an application ID can be at most 18 characters long
Show the answer and explanation
Answer: C
Why this is correct
The third element of a namespace identifier is the application ID. The page says this string can be up to 40 characters long, and if the string is longer than 18 characters, the system truncates the application name and appends it to the prefix. A 32-character ID is therefore valid, because it is under 40, but long enough to be shortened when the identifier is generated. Application developers set the ID when they create the application, and the system uses the application name by default, which is how a long application name ends up as the ID.
Why the other options are wrong
"The ID is rejected, because an application ID can be at most 18 characters long" … Eighteen characters is the length above which the system truncates the name, not the maximum. The page gives the maximum length of the application ID as 40 characters, so a 32-character ID is allowed.
"The customer prefix is shortened to two characters to make room for the long ID" … The truncation rule is written in the application ID row of the page and applies to the application name. The customer prefix is a different element, so a long application ID does not change it.
"The ID is accepted, and the developer can shorten the identifier on the artifacts later" … The identifier cannot be changed or removed from application artifacts, so there is no later step that shortens it on the artifacts.
Numbers to keep apart
Two numbers appear in the application ID row: 40 is the maximum length of the ID, and 18 is the length above which the system truncates the name in the identifier. Choosing a short application ID at creation time keeps the identifier readable, because the identifier cannot be edited on the artifacts afterwards.
