What can the consumer manage and control when subscribing to cloud Software as a Service (SaaS)?
What would you describe is a key characteristic of cloud platform as a Service (PaaS)?
Which properties define a cloud environment?
Which services are typically offered by cloud service providers?
What is a key attribute of cloud services?
What is a key benefit to consumers of cloud services?
Which benefits might be realized by designing a separate infrastructure pool to host network
Ian organization wants to protect the cloud management platform (CMP) from loss due to a site
disaster. To support this requirement, the completed cloud design deliverables include the processes
and procedures for restoring CMP functionality.
What other item should be included in the deliverables to support this requirement?
What are key benefits of ITaaS compared to traditional IT processes?
A. Tiered services, integrated inventory management, and SLA-driven profit model
B. Service catalog, SLA-driven management, and chargeback
C. Strong policies, DevOps, and software licensing
D. Ticket-based service model, cost, and chargeback
* In the ITaas model, corporate IT offers a menu of SaaS, PaaS and IaaS options for business users via
a centralized service catalog. Business users are free to pick and choose cloud services that corporate
IT has vetted, or provide themselves. These users can make informed decisions based on service
pricing and SLAs, and can in many cases can provision services on their own.
* ITaas can be implemented through new consumption models leveraging self-service catalogs
offering both internal and external services; providing IT financial transparency for costs and pricing;
offering consumerized IT such as bring your own device (BYoD) to meet the needs of users. All of
which simplify and encourage consumption of services.
* A service-level agreement (SLA) is a part of a standardized service contract where a service is
formally defined. Particular aspects of the service scope, quality, responsibilities are agreed
between the service provider and the service user.
A cloud design contains multiple hosts that are running a hypervisor. Each host has only two physical
10 Gb network adapters that are aggregated for bandwidth and failover. The physical switch ports for
each host are configured as access ports. Each host will support numerous virtual machines and
network segments. These virtual machines will communicate with other virtual machines on the
same network segments.
Why would overlay networks be required for this design?
A. Support for more than two virtual switches
B. Support for more than one virtual segment
C. Support for more than two virtual machines
D. Support for more than one distributed virtual switch
An overlay network is a computer network that is built on top of another network. Nodes in the
overlay network can be thought of as being connected by virtual or logical links, each of which
corresponds to a path, perhaps through many physical links, in the underlying network.
Virtual overlay networks use tunneling protocols to extend isolated network segments between
servers for multi-tenant data center networks.
