A cloud architect is evaluating an organization’s need to support thousands of virtual machine instances and some form of encryption. Which encryption type should be selected and why?
Storage array encryption to provide centralized management
Full file systems encryption to simplify key management
Network-based encryption to increase security at the cost of server overhead
Self-encrypting storage devices to increase security at the cost of increased overhead
You are creating a cloud infrastructure design for an organization. You learn that, for compliance reasons, the organization needs to maintain a separate set of infrastructures for certain deployed services. Which part of the design will be impacted by this requirement?
Number of service catalogs
Number of compute pools
Service catalog sizing
An architect is designing a cloud. The architect has decided to place the cloud management platform components on a separate set of compute, network, and storage infrastructure from the consumer resources. Why would the architect make this decision?
Provide static and dedicated resources to the management applications without affecting the efficiency ofconsumer resource sharing
Provide static and dedicated resources to the consumer applications without affecting the efficiency of themanagement applications
Provide additional security to the management infrastructure by eliminating exposure to public-facingnetworks
Provide separate billing for the management applications for the consumer’s resources
A cloud architect has included an SDS controller in a cloud design. Which requirement(s) will support the addition of this component to the design?
Monitor storage performance and manually provision storage resources
Provide the ability to programmatically deploy virtual storage resources
Switch array functionality from active/passive to active/active
Provide a redundant front-end for object storage
Software-defined storage (SDS) is an evolving concept for computer data storage software to manage policybased provisioning and management of data storage independent of the underlying hardware. Software-defined storage definitions typically include a form of storage virtualization to separate the storage hardware from the software that manages the storage infrastructure.
An organization is currently using a private cloud to host gaming applications. The private cloud is located in the organization’s data center. These applications have very little static data and no requirements for securing data. Authentication is handled through an external resource. During holiday and vacation seasons, application usage increases significantly and more resources are required. However, the increase only occurs about 10% of the year and the organization wants to maintain performance.
What can be done to meet this requirement?
Deploy global load balances
Create QoS policies during peak usage
Move to a hybrid cloud model
Implement a CDN solution
Hybrid cloud is a cloud computing environment which uses a mix of on-premises, private cloud and third-party, public cloud services with orchestration between the two platforms. By allowing workloads to move between private and public clouds as computing needs and costs change, hybrid cloud gives businesses greater flexibility and more data deployment options. Incorrect:
Not D: A content delivery network (CDN) is a system of distributed servers (network) that deliver webpages and other Web content to a user based on the geographic locations of the
user, the origin of the webpage and a content delivery server.
An organization plans to build a cloud using some of the existing data center infrastructure. Specifically, they want to use the existing FC storage infrastructure to support cloud hosts. However, they want to logically separate the cloud storage traffic from the existing data center storage traffic within this infrastructure. Which mechanism can be used to meet this requirement?
The use of VSANs allows the isolation of traffic within specific portions of the network. If a problem occurs in one VSAN, that problem can be handled with a minimum of disruption to the rest of the network. VSANs can also be configured separately and independently.
Note: Virtual storage area network (VSAN) is a collection of ports from a set of connected
Fibre Channel switches, that form a virtual fabric. Ports within a single switch can be partitioned into multiple VSANs, despite sharing hardware resources. Conversely, multiple switches can join a number of ports to form a single VSAN.
Not A: Microsoft Multipath I/O (MPIO) is a Microsoft-provided framework that allows storage providers to develop multipath solutions that contain the hardware-specific information needed to optimize connectivity with their storage arrays.
MPIO is protocol-independent and can be used with Fibre Channel, Internet SCSI (iSCSI), and Serial Attached SCSI (SAS) interfaces in Windows Server® 2008, Windows Server 2008 R2 and Windows Server 2012.
Not D: Logical Unit Number Masking or LUN masking is an authorization process that makes a Logical Unit Number available to some hosts and unavailable to other hosts. LUN masking operates at Layer 4 of the Fibre Channel protocol.
A cloud architect has included a monitoring application in a cloud design to ensure infrastructure performance meets agreed-upon service levels. The application resides on a virtual appliance. The application vendor provides guidance for sizing the appliance. What will be part of the sizing calculations for the virtual appliance storage?
Number of targetsMessage bus subscribers Data deduplication policies
Number of segments Number of metrics Data deduplicaiton policies
Number of targetsNumber of metrics Data retention policies
Message bus subscribers Number of users Data retention policies
What are general design considerations for inter-cloud links?
Internet connection, network service provider adjacent to the cloud provider, and application behavior
Router and load balancer session synchronization, Internet connection, and network service provideradjacent to the cloud provider
Application behavior, router and load balancer session synchronization, and Internet connection
Network service provider adjacent to the cloud provider, application behavior, and router and load balancersession synchronization
Which categories of network traffic should be isolated from inter-host communication and each other?
Logging and messaging
Cloud services and administration
Administration and storage
Messaging and storage
An organization is considering the use of a cloud gateway to backup services to a public cloud. They will use their existing backup application. What is a design consideration?
Ensuring the cloud storage provider is using the same compression algorithm as the backup software
Ensuring data is encrypted and key management is defined
Ensuring the cloud storage provider is using the same PKI solution as the organization
Ensuring the backup application supports the same authentication mechanism as the public cloud provider
