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?

• A.Number of targetsNumber of metricsData retention policies
• B.Message bus subscribersNumber of usersData retention policies
• C.Number of segmentsNumber of metricsData deduplicaiton policies
• D.Number of targetsMessage bus subscribersData deduplication policies

In which cloud services are policy compliance typically defined in a hybrid cloud deployment?

• A.Orchestration, virtual networking, and portal
• B.Portal, catalog, and orchestration
• C.Virtual networking, portal, and catalog
• D.Catalog, orchestration, and virtual networking

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?

• A.Storage array encryption to provide centralized management
• B.Full file systems encryption to simplify key management
• C.Network-based encryption to increase security at the cost of server overhead
• D.Self-encrypting storage devices to increase security at the cost of increased overhead

What are general design considerations for inter-cloud links?

• A.Network service provider adjacent to the cloud provider, application behavior, and router and load balancer session synchronization
• B.Application behavior, router and load balancer session synchronization, and Internet connection
• C.Router and load balancer session synchronization, Internet connection, and network service provider adjacent to the cloud provider
• D.Internet connection, network service provider adjacent to the cloud provider, and application behavior

A cloud architect is designing a distributed block storage solution that will support application HA. The solution will consist of 10 nodes with all SAS devices. There are five racks available in the data center. Each rack has a single top-of-rack access layer switch with sufficient bandwidth to the aggregate layer. Each node will have multiple connections to the local top-of-rack switch.
The architect wants to provide a design that has the fewest number of storage pools maximizing the number of fault domains. How should the storage pools be designed?

• A.One pool with SSD nodes located in one rackOne pool with all SAS nodes located in a different rack
• B.One pool with SSD nodes distributed equally across five racksOne pool with all SAS nodes distributed equally across five racks
• C.One pool with 50% SSD and 50% SAS nodes distributed equally across five racks
• D.One pool with 50% SSD and 50% SAS nodes located in one rackOne pool with 50% SSD and 50% SAS nodes located in a different rack
