IBM Assessment Foundations of Cloud Computing Architecture V3

1.

What type of cloud computing environment provides and manages some capabilities in-house and has others provided externally?

Public cloud Hybrid cloud Private cloud Community cloud

2.

How does server virtualization reduce cloud computing infrastructure investments?

Virtual server system administrators require a narrower set of IT skills and therefore a smaller support team is needed. Debugging fewer servers running several virtualized workloads is easier for system administrators thanphysical servers running one workload. Software license costs are lower because each virtual server has a base license which allows an unlimitednumber of virtual machines to use the software for free. Optimal server hardware utilization is achieved by consolidating under-utilized physical servers running oneworkload into fewer servers running several virtualized workloads.

3.

How does provisioning take place in a hybrid cloud environment?

A rule-based workflow is usually in place which determines the best location for the workload. Workloads are always provisioned on the public cloud when the private cloud is out of capacity. Workloads can be provisioned anywhere as long as the monitoring data can be integrated in a singledashboard. Hybrid cloud environments have dedicated resource pools for provisioning storage and compute for eachworkload.

4.

How can cloud computing improve service delivery?

By providing monthly or pay per usage billing models By abstracting underlying hardware using virtualization By enabling service providers to provide multi-instance solutions By automating processes used to request and provision workloads

5.

What is a benefit of using IBM's Cloud Computing Reference Architecture V3?

It saves clients time and money by dictating a 100% IBM hardware and software solution. Customers can leverage specific cloud architectures from other customers in similar industries. It saves clients time and money by providing the steps and components required for constructing a cloudimplementation across all deployment models. It speeds up development and reduces errors across the entire development process by leveraging an adhoc and unstructured approach to cloud architecture.

6.

Server consolidation and virtualization initiatives demand more bandwidth per physical system and wide area network environments. Bottlenecks are becoming more pervasive making it increasingly more difficult to spot and remove them in a timely and seamless way. Clearly this has a significant impact on the performance and even the availability of the enterprise network. What must be configured to prevent this?

Quality of service Additional bandwidth Virtual Local Area Network Load balancing of Local Area Networks

7.

What is a valid integration strategy to an existing IBM endpoint security solution when IBM Tivoli Service Automation Manager (TSAM) is used to create an Infrastructure as a Service cloud?

TSAM interacts with the hypervisor to trigger the installation of end point management capabilities in the cloud. Install an agent using its software stack installation capability. The endpoint solution will handle the rest ofthe interaction. TSAM will provision an instance of the existing endpoint security solution so that the newly provisionedvirtual machines can be related to the endpoint management domain. Define virtual machine templates that have the required software already installed. Then TSAM willorchestrate the interaction between the virtual machines and the corresponding endpoint security solution.

8.

Which initial plan gets run when a new service deployment instance is created from a service definition?

Job Plan Build Plan Execution Plan Management Plan

9.

What is the main reason cloud computing is recognized for reducing costs in development centers worldwide?

Automated provisioning Sharp decrease in storage costs Automated project commissioning Sharp decrease in maintenance costs

10.

Why is a change management process important in a cloud environment?

The cloud model requires additional security controls. It helps in the capacity planning for a cloud infrastructure. Service Level Agreements of cloud services may change dynamically. The combination of a cloud delivery model and virtualization makes the infrastructure very fluid and changerapidly.
