Which of the following should be measured with a direct cost chargeback method?
A. Power and cooling consumed
B. CPU cycles used
C. Technical staff
D. Square footage cost of the facility
A range of approaches have been developed for implementing chargeback in an organization, as summarized in the figure below. The degree of complexity, degree of difficulty, and cost to implement decreases from the top of the chart [service-based pricing (SBP)], to the bottom [high-level allocation (HLA)]. HLA is the simplest method; it uses a straight division of IT costs based on a generic metric such as headcount. Slightly more effort to implement is low-level allocation (LLA), which bases consumer costs on something more related to IT activity such as the number of users or servers. Direct cost (DC) more closely resembles a time and materials charge but is often tied to headcount as well.
A company regularly doubles the number of employees ever the summer by hiring on temporary stuff. The company currently pays the same price every month for its email software, equal to the maximum number of employees on staff who have email addresses. The company would like to only pay for the number of active email addresses and is considering migrating to a cloud solution. Which of the following characteristics of cloud computing is the MOST beneficial reason the company should implement a cloud solution?
B. Hardware independence
C. Variable costs
A company would like to move an application to the cloud which resides on a single physical server in their datacenter. The server has two drives, one of which hosts operating system, and the other hosts the application data. The operating system has been showing errors recently and the application data was corrupted last Friday at 4:00PM. Data is backed up every day at 1:00PM. Which of the following would be the BEST option for migrating this application to the cloud?
A. Setup a server in the cloud, install an operating system, install the application and copy the data to the cloud server from last Friday’s backup.
B. Setup a server in the cloud, install an operating system, install and configure the application and copy the data to the cloud server from last Thursday’s backup.
C. Clone or P2V the server with both drivers to the cloud platform.
D. Clone or P2V the server with the application to the cloud platform and copy the operating system to the cloud server.
Use the latest backup of the application data.
Using https instead of http for accessing a cloud service is considered more secure.
HTTPS (also called HTTP over TLS, HTTP over SSL, and HTTP Secure) is a protocol for secure communication over a computer network which is widely used on the Internet.
An organization is planning to host a number of its critical applications in the cloud. Which of the following is the Best way to gain a broad assurance of the cloud provider’s security posture?
A. A review that includes interviewing key security stakeholders and identifying the key controls that they operate.
B. A review that includes security policies, evidence of the controls, physical site assessments and vulnerability scanning.
C. A review that includes the right to audit on a yearly basis and review of the security clauses in the contract.
D. A review that includes security applications, external audits, intrusion detection and firewall policy reviews.
Consumption statistics for individual cloud service offerings is used by which of the following ITIL processes?
A. Supplier management
B. Continuous service improvement
C. Service level management
D. Information security management
ITIL defines Service Management as “a set of specialised organisational capabilities for providing value to customers in the form of services”. The managed service provider will intermediate between the cloud service provider and consumer, aligning the two and ensuring minimal service disruptions.
ITIL Service Level Management aims to negotiate Service Level Agreements with the customers and to design services in accordance with the agreed service level targets. Service Level Management is also responsible for ensuring that all Operational Level Agreements and Underpinning Contracts are appropriate, and to monitor and report on service levels.
Which of the following enables hardware independence?
Virtualization is a conversion process that translates unique IT hardware into emulated and standardized software-based copies. Through hardware independence, virtual servers can easily be moved to another virtualization host, automatically resolving multiple hardware- software incompatibility issues. As a result, cloning and manipulating virtual IT resources is much easier than duplicating physical hardware.
Which of the following are the MOST important benefits of a cloud computing solution for an application development provider? (Select two.)
A. Reduced training time for new developers
B. Reduced storage requirements.
C. Reduced complexity for users.
D. Reduced bandwidth usage.
E. Reduced cost.
F. Reduced development timeframe.
The biggest promise of Azure-based applications is the ability to write them to scale as needed in real-time. Customers will therefore only use the amount of resources they need, rather than budgeting a set amount of resources that can overtax or underutilize their current setup.
Which of the following is an example of SaaS?
A. Offshore help desk support
B. Hosted database software and development tools
C. Hosted email software
D. Hosted network hardware
If you’ve used a web-based email service such as Outlook, Hotmail, or Yahoo! Mail, then you’ve already used a form of SaaS. With these services, you log into your account over the Internet, often from a web browser. The email software is located on the service provider’s network, and your messages are stored there as well. You can access your email and stored messages from a web browser on any computer or Internet-connected device.
One of the strategic reasons to source component technology purchases from multiple providers is to:
A. Avoid vendor lock-in.
B. Influence governmental organizations.
C. Keep vendor prices down.
D. Encourage vendor control.
When it comes to building applications for the cloud, John Gossman, an employee of Microsoft, thinks agility and portability are essential. “You don’t want to get locked in too much to a particular vendor, strategy, technology, whatever,” he says. Likewise, he added, you aren’t likely to last long if your plan is to pick a single public cloud vendor and host everything there.
