Foundations of IBM Cloud Computing Architecture V4 Set 1

1.

What is a typical grid computing usage scenario?

Users get root access to remote instances and install and deploy their own applications configuring the environment for executing MPI applications. Users run applications on a computing infrastructure comprised by a collection of homogeneous nodes that share I/O facilities, operating system processes,and appear as single system. Developers build applications that require a large number of computing resources beyond the size of the local department computing facilities and submit theapplication for execution to internet scale computing infrastructures. Developers have a limited amount of investments for running their web applications and decide to leverage Computing as a Service solutions to increase theirinvestments in computer resources as their applications become more popular.

2.

What are two examples of Advanced Cloud Service Provider services as described in the Cloud Service Provider Adoption Pattern of the IBM Cloud Computing Reference Architecture V4?

platform services customizable store front virtual machine snapshots patch management services brokering of third-party cloud services

3.

In an ITIL managed cloudenvironment, which twoservice transition processes are involved when thememory of a virtual machine is increased?

Event Management Change Management Release Management Capacity Management Configuration Management

4.

Which Software as a Service (SaaS) delivery model is a mixed resource environment, combining localand cloud resources to provide SaaS and rely on both environments to deliver true end-to- endfunctionality?

Full Cloud Hybrid Cloud Primary Hybrid Extended Cloud

5.

What are the benefits for an organization utilizing dynamic infrastructure for running its workloads?

Organizations no longer need their own data centers which reduces the cost of their own IT expenditure. Dynamic infrastructure provides the means to achieve elastic scalability which ensures that organizations keep constant and predictable costs for the ITresources utilization. By leveraging pooled IT resources, dynamic infrastructure provides flexible IT capacity which better aligns the allocation of IT resources to business processneeds of the organization Dynamic infrastructure is essential for the implementation of application service catalogs which reduces the time to market of such applications and increasesthe organization's business revenue.

6.

What is a service catalog as it relates to cloud computing services?

It is a service request ticketing system. It is an integral part of deploying sen/ices in a cloud. It is a shopping cart format for requesting IT services and hardware. It is a mechanism to accept credit card payments for cloud services

7.

Which statement is true for virtualization?

It runs on UNIX-based operating systems only. It is an interchangeable term for cloud computing. It separates physical hardware into various pool resources. It can only be applied in the context of hybrid and public clouds

8.

Which IBM cloud offering provides flexibility and choice with options to use bare metal, vitalized dedicated, or shared servers?

IBM SoftLayer IBM Cloud Orchestrator IBM Service Management IBM Cloud Managed Services

9.

What greatly affects the speed of cloning VMware templates?

speed of disk type of network card format of the VM image architecture of the video card

10.

What is Software Defined Network (SDN) in reference to cloud computing?

SDN are security standards that increase environment performance. SDN disables group conflict resolution if the environment is configured for replication. SDN provides a breakdown, by time, of the quantity and distribution of the unbind transactions found within the audit log. SDN is the framework to automatically manage and control a large number of network devices and services in a multi-tenant environment.
