,Q1. In an ArcGIS Enterprise 7.0 deployment, Web Adaptor is configured for both
Portal for ArcGIS and ArcGIS Server. During a load test, portal requests
intermittently fail with 503 errors while server requests succeed. What is the most
likely cause and best resolution?
A. Web Adaptor is configured with HTTP only; switch to HTTPS to resolve the issue.
B. Portal for ArcGIS is reaching its maximum number of concurrent users; increase the
portal's private machine limit.
C. The ArcGIS Web Adaptor is not properly configured to forward the original host
header; use the 'portalHostname' property.
D. The load balancer is sending health checks to the Web Adaptor, which returns 503
because the adaptor is not a valid endpoint; configure the load balancer to check a
dedicated health endpoint.
Correct Answer: D. The load balancer is sending health checks to the Web Adaptor,
which returns 503 because the adaptor is not a valid endpoint; configure the load
balancer to check a dedicated health endpoint.
Rationale: The Web Adaptor is not a service endpoint and returns 503 for health checks.
The load balancer should be configured to use a valid health check endpoint, such as
/arcgis/rest/info or /portal/sharing/rest/info, to avoid false negatives. The other options ar
e
either irrelevant or misdiagnose the issue.
Why Wrong:
A - HTTP vs HTTPS is not related to intermittent 503 errors during load testing.
B - Portal's concurrent user limit does not produce 503; it would typically return a
specific error or queue requests.
C - Host header forwarding is not the cause of 503 errors; it would affect URL
generation, not availability.

Adaptor Configuration
Q2. When integrating ArcGIS Enterprise with SAML-based identity provider, which
configuration step is essential to ensure seamless single sign-on for Portal users
without prompting them to select an identity provider?
A. Set the 'Enable SAML' checkbox and disable built-in accounts.
B. Configure the 'SAML Identity Provider' to use HTTP-POST binding for all
responses.
C. Set the 'Portal URL' to the fully qualified domain name that matches the SAML
assertion's audience.
D. Enable 'Federated Authentication' and set the 'SSO' integration level to 'Prefer
SAML'.
Page 3
, Correct Answer: C. Set the 'Portal URL' to the fully qualified domain name that
matches the SAML assertion's audience.
Rationale: For seamless SSO, the portal URL must match the audience restriction in the
SAML assertion; otherwise, the portal will not recognize the assertion and will prompt the
user to choose an identity provider. The other options are not the essential step for
avoiding the prompt.
Why Wrong:
A - Disabling built-in accounts is a security measure but does not affect the SSO
prompt.
B - HTTP-POST binding is common but not the key factor for seamless experience.
D - There is no such integration level as 'Prefer SAML' in Portal for ArcGIS.

Q3. You are tuning an ArcGIS Server 7.0 site that hosts a map service with 10% of
features participating in a dynamic table join. The service is used by a web app that
frequently queries by attribute. Which configuration will most significantly improve
query performance?
A. Enable 'Cache on Demand' for the map service.
B. Set 'Maximum number of records returned by server' to 2000.
C. Enable 'Server-side time zone' and set it to UTC.
D. Enable 'Feature Access' and 'Query' operations, and set 'Enable dynamic
redefinition' to true.
Correct Answer: D. Enable 'Feature Access' and 'Query' operations, and set 'Enable
dynamic redefinition' to true.
Rationale: Enabling Feature Access with Query operations allows the server to perform
queries directly on the database, and dynamic redefinition allows the join to be executed
on the server side, reducing data transfer and improving performance. The other options
do not address the join-related query bottleneck.
Why Wrong:
A - Caching on demand is for tile services, not dynamic map services.
B - Limiting records returned may affect results but does not improve query
performance.
C - Time zone settings do not impact query speed.

site that was backed up using the webgisdr utility. After restoring the Portal for
