An AEM Architect is moving existing content from an on-premise AEM to an AEM Cloud Service instance using the Content Transfer Tool. As part of the initial source preparation, the Architect is going to run the offline compaction on the on-premise AEM.
What other two actions should the Architect do to the on-premise AEM before proceeding with the extraction phase? (Choose two.)
Refer to the exhibit.

A customer with an existing AEM implementation wants to enrich product pages with technical data coming from their PIM system. The PIM system sits behind an API Management solution that publicly exposes the PIM API's as RESTful web services with basic authentication as the security mechanism. Data consistency with the PIM and secure access to the APIs are key elements of the integration.
How should the Architect set up the integration between AEM and the PIM?
A customer's photo gallery site uses query parameters to filter photo search results. The site experiences high AEM Publish server load when users filter photos on the site. The customer would like to identify the cause of this issue.
What should the Architect investigate first?
A client has set up branded error pages in AEM to be presented in case of HTTP 400 and HTTP 500 errors on an AEM hosted website. The website pages are under "/content/xbrand/fr/fr/" directory. The error pages are located under "/content/xbrand/fr/fr/error-docs/". The architect notices that the error pages are being invalidated too whenever any other site page is published. Which solution would prevent the error pages from invalidating when publishing any other site page?
