問題1
The sales organization within a large enterprise has determined the need to immediately implement a mobile sales tool for its field staff. There are two SaaS solutions available that meet their requirements.
The CIO wants to develop the solution in-house and claims that IT can develop the application at only slightly more cost than the SaaS solutions, and it would be more secure. Estimated time to deliver the application from internal IT is 10 weeks.
Who should make the decision to determine the best solution?

問題3
Refer to Scenario 1 below.
An IT department is offering 50 Service Offerings in their service catalog to meet all the application developers' needs. Many of the variants have a very small number of associated instantiations. A "big data" platform is offered and being actively utilized by a team of data scientists.
All services are sourced from within the private cloud. The developers are able to customize the platform's compute, storage, protection and network configuration upon instantiation. They can also provision additional resources after the initial instantiation through an upgrade service within the catalog. Because of the culture of the organization, no chargeback mechanism is implemented.
Within six months, IT experiences these problems:
(a). Developers are complaining of poor and inconsistent performance
(b). Resource utilization has far exceeded expectations
(c). The environment has become very complex
(d). Since the resource pools are shared throughout the organization, IT has been unable to identify usage patterns, making capacity planning very difficult
What can the IT department do to address problem (a)?
Refer to Scenario 1 below.

問題4
During an initial discovery of a company's environment you realize there are applications with unique risk considerations. In anticipation of moving the organization to ITaaS, how should these application security requirements be managed?

正確答案: C
問題5
Refer to Scenario 7.
-- Exhibit -
Scenario 7.
A web hosting company has been growing steadily over the past year. Their single data center is at maximum capacity for power, space and cooling, and their physical infrastructure is also running at capacity. They are evaluating the feasibility of obtaining another data center in a remote location to enable further growth.
One of the web hosting company's eCommerce customers notifies them that they are launching an enormous holiday sale, beginning in a few weeks. They expect utilization of their virtual server farm to double or triple for the next three to six months. The web hosting company cannot deploy the needed resources in a new data center in time for the sale. They opt to purchase services from a cloud service provider using a pay-as-you-go model.
Over the next two weeks, Layer 2 connectivity is established between the two sites. The web hosting company's IT staff works with the CSP to configure the necessary physical and virtual infrastructure. All traffic to the public cloud is routed through the private data center, across the Layer 2 connection. A local load balancer is deployed in the private data center. Orchestration tools are configured to burst the service into the public cloud automatically when utilization reaches 80%.
-- Exhibit -
To test the functionality of the new infrastructure, a load simulator is used to increase utilization on the servers. At 80% utilization, the orchestration tools provision the required resources in the public cloud. However, the utilization on the private cloud resources continues to increase, while the utilization on the public cloud resources remains at 0%.
What is the most likely cause of this problem?

問題7
A public cloud service provider is facing several challenges in its IT operations:
1 - Rapidly increasing storage capacity needs, forcing frequent data migrations
2 - Consolidation of disparate Fibre Channel fabrics from multiple connectivity vendors
3 - Deployment of several types of hypervisors simultaneously in production
4 - Long-term archival of very large volumes of tenant data for compliance
5 - Very limited application mobility across data centers, using array-based replication
Which challenge(s) would VPLEX address?

A cloud service provider has just delivered a presentation to your organization. During the ROI section of the presentation the vendor described how their predefined service catalog would dramatically reduce service commissioning timing and guarantee a consistent user experience. However, the presenter did not attach a direct financial value to the service catalog.
You are helping to create an initial justification report for the organization. How could you categorize the non-financial benefits of the service catalog?

Refer to the exhibit.
You have been hired to assist with a migration to an ITaaS environment. The company has offices
in Atlanta, Dubai, and London, with 5000, 2000, and 3000 employees, respectively. A data center exists in each location, and most services have been virtualized. Messaging services are provided locally to the user.
You have just performed an assessment of the environment. The results are shown in the exhibit.
The CIO is interested in closing one of the data centers and migrating some or all of the services to a public cloud service provider (CSP). Any services that do not get migrated to the CSP will be hosted at one of the other two data centers. Network latency averages 8 milliseconds between the Atlanta and London offices, and 10 milliseconds between the London and Dubai offices. Traffic between Atlanta and Dubai is routed through London.
The eCommerce application is external facing and is hosted at all three data centers. Atlanta services 50% of the users in North and South America. London services 40% of the users in Europe and Asia. Dubai services 10% of the users in Africa and Australia.
You have tentatively chosen a CSP that is housed in Frankfurt, and would have access to 3 Gb/s of network bandwidth to the facility. The CSP's service levels are as follows:
-RPO: 4 hours -RTO: 1 hour -Availability: 99.995%
Your recommendation is to close the Dubai data center over a one-year time horizon.
What migration strategy would you recommend for the services that are currently hosted in the Dubai data center, and why?

問題10
An organization is expanding its private cloud to a hybrid deployment to accommodate growth in its web / database application. The CIO is concerned about the security risks associated with the public cloud. They do not view firewall security as adequate to protect important company data. Encryption is being considered as a security measure.
As the cloud architect, what would you recommend?
