The contract should include requirements for notification by the cloud provider to the cloud customer upon the receipt of such an order. This serves a few important purposes. First, it keeps communication and trust open between the cloud provider and cloud customers. Second, and more importantly, it allows the cloud customer to potentially challenge the order if they feel they have the grounds or desire to do so.

Explanation:
Many web applications offer redirect or forward pages that send users to different, external sites. If these pages are not properly secured and validated, attackers can use the application to forward users off to sites for phishing or malware attempts. These attempts can often be more successful than direct phishing attempts because users will trust the site or application that sent them there, and they will assume it has been properly validated and approved by the trusted application's owners or operators. Security misconfiguration occurs when applications and systems are not properly configured for security--often a result of misapplied or inadequate baselines. Insecure direct object references occur when code references aspects of the infrastructure, especially internal or private systems, and an attacker can use that knowledge to glean more information about the infrastructure. Sensitive data exposure occurs when an application does not use sufficient encryption and other security controls to protect sensitive application data.

Explanation
Interoperability is the ease with which one can move or reuse components of an application or service. This is maximized when services are designed without specific dependencies on underlying platforms, operating systems, locations, or cloud providers.

Explanation:
Fences are physical controls; carpets and ceilings are architectural features, and a door is not necessarily a control: the lock on the door would be a physical security control. Although you might think of a door as a potential answer, the best answer is the fence; the exam will have questions where more than one answer is correct, and the answer that will score you points is the one that is most correct.
