Global report suites can aggregate data from multiple report suites into one high-level report. This allows you to view data from multiple report suites at once, enabling you to quickly compare performance across sites, countries, or other groupings. Additionally, global report suites can aggregate historical data, allowing you to see the overall performance of a site over a period of time.
Rollups, on the other hand, are used to aggregate data from multiple report suites into one report suite. This allows you to view data from multiple report suites at once, but it only reports data from the point they were implemented. As a result, rollups cannot be used to view historical data, as they will only report data from the point they were implemented. Additionally, rollups are only processed at midnight each night, while global report suites report data with standard latency.

The two correct features of Rollup Reports are as follows: A. Rollup report suites can include a maximum of 40 child report suites. B. When you add a report suite to an existing rollup, historical data is included in the rollup. For more information, please refer to the Adobe Analytics Developer Professional study guide.

This method is recommended by Adobe Analytics Developer Professional documents, as it allows you to easily customize the metrics used in a table in Workspace. You can use a calculated metric to modify the name of an existing metric, or to derive a new metric from an existing one [1].

CORS is a web security method that allows for limited cross-domain communication and is supported by Experience Cloud ID. It enables web applications to access resources located on a different domain than the one from which the request originated. This is important for ensuring that web applications are secure and that data is not leaked to malicious actors. CORS is implemented by setting certain headers on the server, allowing the web application to access resources from different domains. Additionally, CORS can also be used to authenticate users, allowing for secure access to resources.

The fpCookieDomainPeriods value determines the cookie domain on which the Analytics cookie will be set. For the domain https://xyz.co.region, the fpCookieDomainPeriods value should be set to 2. This will set the cookie domain to be ".co.region". Setting the value to 1 would set the cookie domain to be ".region", which would not be appropriate for this domain. Setting the value to 3 would set the cookie domain to be "xyz.co.region", which would also not be appropriate.
