B2C Commerce Governance and Quotas are a set of rules and limits that apply to B2C Commerce instances to ensure the efficiency and stability of solutions built on the platform. The following considerations should be kept in mind when considering B2C Commerce Governance and Quotas:
Object quotas status is updated with an up to 20-minute delay. Therefore, a Solution Architect must consider this delay when performing calculations related to traffic and limits. Object quotas are limits on the number of objects that can be created or stored in B2C Commerce, such as products, categories, customers, orders, etc. The object quotas status shows the current usage and remaining capacity of each object quota. However, the status is not updated in real time, but with an up to 20-minute delay. This means that the Solution Architect should account for this delay when estimating the traffic and limits for each object quota.
If an enforced quota is exceeded, an exception is thrown, which prevents the current operation from completing. The Solution Architect should design the solution so that the exception can be caught within a customization. Enforced quotas are quotas that are strictly enforced by B2C Commerce and cannot be exceeded or changed by customers. Examples of enforced quotas are API calls per hour, script execution time, cache size, etc. If an enforced quota is exceeded, B2C Commerce throws an exception that stops the current operation from completing. This can result in errors or failures in the storefront or backend processes. The Solution Architect should design the solution so that the exception can be caught within a customization and handled gracefully.
Option B is incorrect because sandbox quotas cannot be softened by exporting them from a production instance and importing them onto a sandbox instance. Sandbox quotas are fixed and cannot be changed by customers. Option C is incorrect because the Solution Architect cannot assume that quota violations have not occurred unless a site is experiencing performance issues. Quota violations can occur without affecting the site performance, but they can still cause errors or failures in certain operations or processes. Reference:
