During a major upgrade of the Guidewire Cloud platform, a customer experiences unexpected downtime for their production environment. What is the MOST…

Guidewire Cloud Standards are a set of mandatory development and operational practices. Their primary purpose is to ensure that customer configurations and integrations are built in a way that does not interfere with the underlying platform architecture. By adhering to these standards, customers ensure their solution remains compatible with future platform versions managed by Guidewire. This significantly reduces the risk of customizations causing failures during an upgrade, which is a common source of unexpected downtime. The standards promote a "cloud-native" approach that separates customizations from the core product, facilitating smoother, more predictable upgrades.

A. Customer involvement, especially for testing (e.g., User Acceptance Testing), is a critical part of any successful upgrade process, even when following Cloud Standards.

B. While rollback capabilities exist, the primary function of the standards is proactive (preventing issues) rather than reactive (fixing them after they occur).

D. Guidewire coordinates the upgrade schedule with the customer, but the standards themselves are technical rules, not scheduling agreements.

2. Guidewire Documentation, "Upgrading in Guidewire Cloud," Section 2.1, "Customer Responsibilities." This document outlines the necessity of customer testing and validation, which contradicts the idea of eliminating customer involvement.
