Exam Identity-and-Access-Management-Architect Topic 7 Question 65 Discussion

Actual exam question for Salesforce's Identity-and-Access-Management-Architect exam
Question #: 65
Topic #: 7
Universal Containers (UC) wants to implement SAML SSO for their internal of Salesforce users using a third-party IdP. After some evaluation, UC decides NOT to SSO set up My Domain for their Salesforce org.
How does that decision impact their SSO implementation?

Suggested Answer: D Vote an answer

Explanation
This is because without My Domain, Salesforce will not know in advance what Identity Provider (IdP) to use for SSO, since it does not even know yet what Organization the user is trying to log in to1. SP-initiated SSO is the scenario where the user starts with a Salesforce link (login page, deep link, Outlook Sync URL, etc.) and then gets redirected to the IdP for authentication2. Without My Domain, SP-initiated SSO requires that the user do an IdP-initiated SSO at least once first so that Salesforce can set a cookie in their browser identifying the IdP1. The other options are not correct for this question because:
IdP-initiated SSO will work without My Domain, as long as the user starts SSO at the IdP and sends the identity information to Salesforce along with SAML protocol information that identifies the Organization and the IdP2.
Neither SP- nor IdP-initiated SSO will not work is false, as explained above.
Either SP- or IdP-initiated SSO will work is false, as explained above.
