When is a virtual machine susceptible to attacks while a physical server in the same state would not be?
Correct Answer: D
Explanation A virtual machine is ultimately an image file residing a file system. Because of this, even when a virtual machine is "powered off," it is still susceptible to attacks and modification. A physical server that is powered off would not be susceptible to attacks.
Question 87
What is a key capability or characteristic of PaaS?
Correct Answer: C
Explanation PaaS should have the following key capabilities and characteristics: - Support multiple languages and frameworks: PaaS should support multiple programming languages and frameworks, thus enabling the developers to code in whichever language they prefer or the design requirements specify. In recent times, significant strides and efforts have been taken to ensure that open source stacks are both supported and utilized, thus reducing "lock-in" or issues with interoperability when changing CSPs. - Multiple hosting environments: The ability to support a wide variety of underlying hosting environments for the platform is key to meeting customer requirements and demands. Whether public cloud, private cloud, local hypervisor, or bare metal, supporting multiple hosting environments allows the application developer or administrator to migrate the application when and as required. This can also be used as a form of contingency and continuity and to ensure the ongoing availability. - Flexibility: Traditionally, platform providers provided features and requirements that they felt suited the client requirements, along with what suited their service offering and positioned them as the provider of choice, with limited options for the customers to move easily. This has changed drastically, with extensibility and flexibility now afforded to meeting the needs and requirements of developer audiences. This has been heavily influenced by open source, which allows relevant plug-ins to be quickly and efficiently introduced into the platform. - Allow choice and reduce lock-in: PaaS learns from previous horror stories and restrictions, proprietary meant red tape, barriers, and restrictions on what developers could do when it came to migration or adding features and components to the platform. Although the requirement to code to specific APIs was made available by the providers, they could run their apps in various environments based on commonality and standard API structures, ensuring a level of consistency and quality for customers and users. - Ability to auto-scale: This enables the application to seamlessly scale up and down as required to accommodate the cyclical demands of users. The platform will allocate resources and assign these to the application as required. This serves as a key driver for any seasonal organizations that experience spikes and drops in usage.
Question 88
Which of the cloud cross-cutting aspects relates to the ability for a cloud customer to easily remove their applications and data from a cloud environment?
Correct Answer: A
Explanation Reversibility is the ability for a cloud customer to easily remove their applications or data from a cloud environment, as well as to ensure that all traces of their applications or data have been securely removed per a predefined agreement with the cloud provider.
Question 89
Which standards body depends heavily on contributions and input from its open membership base?
Correct Answer: B
Question 90
The European Union passed the first major regulation declaring data privacy to be a human right. In what year did it go into effect?
Correct Answer: C
Explanation Adopted in 1995, Directive 95/46 EC establishes strong data protection and policy requirements, including the declaring of data privacy to be a human right. It establishes that an individual has the right to be notified when their personal data is being access or processed, that it only will ever be accessed for legitimate purposes, and that data will only be accessed to the exact extent it needs to be for the particular process or request.
