Prisma Access provides a dedicated, centralized notification profile framework specifically for surfacing operational incidents such as tunnel instability, and it is this framework - not a tunnel-specific checkbox or a dashboard-level email setting - that the engineer needs to configure. A notification profile lets an administrator define the conditions that should trigger an alert (including IPSec tunnel down or flapping conditions for Remote Networks), select the delivery method (email or webhook), and optionally scope the profile to specific subtenants, giving the engineer exactly the proactive, condition-based alerting needed to catch intermittent instability rather than only discovering it after users report symptoms. This makes option A the correct and only fully supported mechanism among the four choices. There is no " tunnel log notification rule " object as a distinct configuration construct in Prisma Access (option B); alerting is generated through notification profiles, not through a rule attached directly to log entries. The operational or SASE health dashboard (option C) provides a visual, near-real-time operational view of tunnel and infrastructure status, but it is a monitoring surface an administrator has to actively check, not an automated email-alerting configuration point in itself - dashboards do not natively " send " alerts without being paired with a notification profile. Option D describes a checkbox that does not exist as part of standard remote network IPSec tunnel configuration; monitoring and alerting is configured separately through Incidents and Alerts, not inline during tunnel setup.

Preventing sensitive content specifically - such as financial information - from being uploaded to a generative AI application requires content-aware inspection capable of recognizing patterns like account numbers, financial statement data, or other regulated data types within the actual payload of the upload, which is precisely the function Enterprise DLP is designed to perform. AI Access Security integrates with Enterprise DLP so that an administrator can build a rule targeting the data patterns that constitute " financial information,
" and apply it specifically to traffic destined for sanctioned or monitored generative AI applications like ChatGPT, blocking the upload at the content level regardless of the file format or transport mechanism used.
This makes Enterprise DLP the correct complementary control to a Security policy, and option B the correct answer. File Blocking (option A) operates on file type and extension, not on the semantic content of a file or a text-based upload - it cannot selectively identify " financial information " within an otherwise permitted file type, so it is not a content-aware control suited to this requirement. URL Filtering (option C) governs access to categorized websites and can restrict or allow entire domains, but it has no capability to inspect the content of an upload for sensitive data patterns; it is a destination-control mechanism, not a data-loss-prevention mechanism. A vulnerability profile (option D) is designed to detect exploitation attempts against known software vulnerabilities, which is entirely unrelated to inspecting outbound user-submitted content for sensitive data.

Single sign-on for PAB users accessing public cloud SaaS applications is centrally brokered through the Cloud Identity Engine, which serves as the identity integration point between the organization ' s corporate IdP - Azure AD/Entra ID in this scenario - and the applications and services users access through PAB, rather than being handled by any browser-native or per-application mechanism. Establishing this Cloud Identity Engine-to-IdP integration is what allows the corporate authentication session and identity attributes to be recognized consistently and passed through automatically as the user navigates to sanctioned SaaS applications like Microsoft 365 via PAB, delivering the seamless SSO experience described in the question, which makes option D the essential, correct integration. There is no PAB feature involving direct integration with Microsoft ' s own Conditional Access policy engine as the SSO enablement mechanism (option A); Conditional Access is a Microsoft Entra-native capability that can complement an SSO deployment but is not itself the integration point that establishes SSO through PAB. A " browser-specific SSO extension " (option B) is not the documented architecture for how PAB delivers SSO to cloud applications - SSO is achieved through the identity broker relationship with Cloud Identity Engine, not through a separate extension component layered on top. Manually configuring individual user authentication tokens within the PAB profile (option C) is neither how SSO is designed to function nor a scalable or supported approach; it would defeat the purpose of automated, centrally managed single sign-on entirely.

The ZTNA Connector initiates all communication outbound, resolving the fully qualified domain name of its assigned Prisma Access cloud gateway and establishing a secure, brokered tunnel to it; correct DNS resolution on the host or network where the connector is deployed is therefore a hard prerequisite for the very first handshake to occur. If the connector ' s DNS settings are misconfigured - pointing to a resolver that cannot resolve the gateway FQDN, or lacking a route to reach that resolver - the connector will fail before it ever gets to the point of negotiating a tunnel, which produces the " fails to establish a connection " symptom described in the question rather than a degraded or unstable connection. This is why option A is the most direct root cause among those listed. Because the connector ' s design is entirely outbound-initiated, it does not require inbound NAT traversal or a publicly reachable listener, so a double NAT (option B) does not, by itself, block the connector from reaching the cloud gateway the way it would for an inbound-listening service.
A dynamic IP address (option C) is explicitly supported, since the connector does not depend on a stable, registered public IP for its outbound session. High latency (option D) can degrade performance and increase connection setup time, but it does not categorically prevent the tunnel from establishing, whereas an unresolved FQDN prevents the connection attempt from ever being initiated correctly.

Explicit Proxy deployments that cannot rely on the GlobalProtect agent are, by definition, working purely through browser-based PAC-file traffic redirection, with no endpoint software available to perform seamless, transparent identity handoff on the user ' s behalf the way an agent-based mechanism such as Kerberos single sign-on typically would. In this agentless context, the authentication method that is actually supported and functional is browser-redirect-based SAML: when a user ' s traffic is proxied, they are redirected to the organization ' s IdP login page in the browser itself, complete the SAML authentication flow there, and a resulting session cookie or token is used to authenticate subsequent proxy sessions - a mechanism that requires nothing installed on the endpoint beyond a standard browser, making option C the correct and supported answer. Kerberos (option B) fundamentally depends on integrated, agent-assisted ticket exchange with a domain controller and is not a supported, functioning mechanism for authenticating mobile users in an agentless Explicit Proxy scenario, since there is no local component to negotiate the Kerberos ticket transparently on the endpoint ' s behalf. LDAP (option A) as a direct, standalone authentication method for agentless mobile-user Explicit Proxy sessions is likewise not the supported mechanism in this scenario; LDAP is more commonly used as a backend directory lookup paired with other authentication flows rather than as the browser-facing mechanism itself. Generic " SSO " as a labeled, distinct authentication method (option D) is not how Prisma Access categorizes its supported Explicit Proxy authentication types; SAML is the specific, documented protocol used to deliver that single sign-on experience.
