- A
The identity provider's metadata must be imported into the firewall.
The metadata includes the IdP's public key, endpoints, and binding information needed for SAML communication.
- B
A certificate from a public CA for the SAML identity provider.
Why wrong: The identity provider's certificate must be imported into the firewall, but it can be self-signed; a public CA is not required.
- C
The firewall must be configured as a SAML identity provider.
Why wrong: The firewall acts as the Service Provider (SP), not the IdP.
- D
User-ID must be configured to poll the SAML identity provider.
Why wrong: User-ID polling is not used for SAML; user identity is asserted through SAML assertions.
Question 94 of 516
SAML Identity Provider Metadata for Service Provider
This PCNSE practice question tests your understanding of securing users and applications with authentication. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which of the following is required for SAML-based single sign-on to work with a Palo Alto Networks firewall acting as the service provider?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The identity provider's metadata must be imported into the firewall.
For SAML-based single sign-on (SSO) with a Palo Alto Networks firewall acting as the service provider (SP), the firewall must trust the identity provider (IdP). This trust is established by importing the IdP's SAML metadata (which includes the IdP's entity ID, single sign-on URL, and signing certificate) into the firewall. Without this metadata, the firewall cannot validate SAML assertions from the IdP, making authentication impossible.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The identity provider's metadata must be imported into the firewall.
Why this is correct
The metadata includes the IdP's public key, endpoints, and binding information needed for SAML communication.

- ✗
A certificate from a public CA for the SAML identity provider.
Why it's wrong here
The identity provider's certificate must be imported into the firewall, but it can be self-signed; a public CA is not required.
- ✗
The firewall must be configured as a SAML identity provider.
Why it's wrong here
The firewall acts as the Service Provider (SP), not the IdP.
- ✗
User-ID must be configured to poll the SAML identity provider.
Why it's wrong here
User-ID polling is not used for SAML; user identity is asserted through SAML assertions.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume a public CA certificate is required for SAML trust (Option B), but in reality, SAML uses a direct trust model where the SP explicitly trusts the IdP's self-signed certificate via metadata import, not through a public PKI hierarchy.
Detailed technical explanation
How to think about this question
Under the hood, SAML SSO relies on a pre-established trust relationship defined by exchanging metadata XML files. The IdP metadata contains the IdP's public key (used to verify the digital signature on SAML assertions) and the SSO endpoint URL. When a user attempts to access a resource, the firewall (SP) generates an AuthnRequest, redirects the user to the IdP, and upon successful authentication, receives a signed SAML response. The firewall then validates the signature using the imported IdP certificate and extracts the NameID (typically the username) to map to a local user or group for policy enforcement.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the PCNSE exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.

Same concept, more angles

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Refer to the exhibit. Which configuration is required in the authentication profile 'SAML-Auth'?
easy- ✓ A.SAML identity provider profile
- B.LDAP server profile
- C.RADIUS server
- D.Kerberos realm
Why A: The exhibit shows a SAML-based authentication flow where the firewall redirects the user to an external identity provider (IdP) for authentication. The authentication profile 'SAML-Auth' must reference a SAML identity provider profile to define the IdP metadata, entity ID, SSO URL, and certificate binding. Without this profile, the firewall cannot initiate or validate SAML assertions, making option A the only correct choice.
