security policy and entitlement
Which part of the Cloud Computing Management Platform is used to manage the infrastructure?
OSS-Operational Support Services
What is a characteristic of a cloud computing architecture?
scalable and elastic
A large enterprise is experiencing considerable cost increases in supplying physical hardware to their application development team primarily for testing. They are looking to virtualize most of their test lab requirements but at this time they do not have any virtualization technology, middleware, or hardware capable to support such a service. They would also like a system that includes provisioning request management with multi-level approval capabilities. They also need a solution that can be up and running as quickly as possible. Which IBM cloud solution offering is best suited for this client scenario?
Service management includes policies to assure service delivery and the correlation of resources in order to achieve desired compliance patterns. Which service management component includes these capabilities?
What is the advantage of virtual networks in a cloud computing environment?
to provide custom private addressing for cloud-based servers
What needs consideration when deploying cloud computing environments in a physical facility?
location of users connecting to the cloud data center
At which network layer does the widespread adoption of server virtualization technologies drive a significant expansion?
Layer 2 Domains
What are the resulting characteristics from the implementation of a governance and audit management program in a cloud computing environment?
a program that defines when, how, and where to collect log information
A drawback of using Spanning Tree Protocol is that in order to avoid loops in a Layer 2 network, a tree topology must be enforced by disabling a subset of the available links. What percentage of links are disabled?
What are two benefits automation provides for cloud computing? (Choose two.)
reduces costly manual interventions
maintains and improves quality and cost per IT service
A key driver of Software as a Service (SaaS) growth is a SaaS vendor's ability to provide a price that is competitive with on-premises software. Which statement describe the best pricing licensing definition?
SaaS applications are normally modeled as pay-as-you-go and SaaS vendors typically price their applications based on some usage parameters.
If security is the primary concern, which type of cloud infrastructure is best suited for multi-client environments?
A user in the marketing department is looking for an inexpensive way to make a customer list easily accessible to multiple users. Which aspect of a public cloud should concern this user the most?
In order to provide a consistent and secure e-mail service to its users worldwide, a company has implemented a corporate e-mail solution in its own centralized data center on individual servers. The company is considering integrating e-mail services with other collaboration capabilities such as video, chat, and Web conferencing. Which computing service describes this type of architecture? 11
A customer has heard a lot about Amazon and their EC2 offering. Which comparable IBM offering should be discussed with this customer?
IBM SmartCloud Enterprise
Which option is a key business requirement for a hybrid cloud deployment model?
secure broker environment
One of the steps for cloud adoption is standardizing platforms. Which sentence describes this?
Resources, applications, and hardware assemblies can be moved from one deployment system to another
Why is the data center an important consideration during cloud computing infrastructure design?
It provides a key component in the management, disaster recovery, and cost equation when selling cloud services
How can cloud computing environments save energy?
Because they use virtualization techniques to separate the software from the characteristics of physical servers, certain costly energy features such as multiple power supplies are dropped.
What is a characteristic of a hybrid cloud deployment model?
workload overflow management
What are two ways cloud computing relates to dynamic infrastructure? (Choose two.)
visualizes infrastructure resources
optimizes the IT infrastructure through virtualization r
