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

What needs to be considered when designing a distributed storage solution?

A. Multiple management tools

B. Fault domain detection and isolation to ensure data availability

C. RAID configuration to ensure a drive failure is avoided

D. Automated storage tiering to enable efficient use of drive

A cloud design contains multiple hosts that are running a hypervisor. Each host has only two physical 10 Gb network adapters. The hosts reside in different subnets but can communicate with each other. Each host will support numerous virtual machines and network segments.

What is needed to support a network segmentation in the current configuration?

A. IDS

B. NVGRE

C. MLAG

D. VLAN

A cloud architect is designing a private cloud for an organization. The organization has no existing backup infrastructure. They want to offer consumers the ability to backup virtual machine instances using image-based backups.

What should the cloud architect look for when selecting a backup application for this environment?

A. Virtual machine hardware is on the backup application vendor's compatibility list

B. Hypervisor servers' hardware is on the backup application vendor's compatibility list

C. Backup application can be integrated with the selected CMP components

D. Backup application supports a cloud gateway for accessing the cloud-based virtual machines

When implementing QoS across a cloud network, how is storage traffic usually prioritized?

A. Most important

B. More important than tenant traffic but less important than management traffic

C. More important than management traffic but less important than tenant traffic

D. Least improtant

An organization wants to provide its developers with the ability to deploy virtual machines. These virtual machines have software and libraries installed that are used to develop applications. Each virtual machine will be configured with the same IP address and will be able to download application code from a central server. Which will be included in the design to support these requirements?

A. VSANs and virtual firewall appliances

B. VLANs and virtual firewall appliances

C. VLANs and virtual IDS appliances

D. VXLANs and an OS firewall

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?

A. Ensuring the cloud storage provider is using the same compression algorithm as the backup software

B. Ensuring data is encrypted and key management is defined

C. Ensuring the cloud storage provider is using the same PKI solution as the organization

D. Ensuring the backup application supports the same authentication mechanism as the public cloud provider
