E20-020 Online Practice Questions and Answers

An organization wants to deploy a block storage in the cloud using a storage array that is accessible through the iSCSI protocol. The hosts support iSCSI.

Why would network segmentation be included in the design to support this requirement?

A. Secure all traffic between the storage array and the hosts

B. Enable CHAP between the array and hosts

C. iSCSI traffic is not supported on networks with other types of traffic

D. Enable LUN masking capabilities of the array

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?

A. Provide static and dedicated resources to the management applications without affecting the efficiency ofconsumer resource sharing

B. Provide static and dedicated resources to the consumer applications without affecting the efficiency of themanagement applications

C. Provide additional security to the management infrastructure by eliminating exposure to publicfacingnetworks

D. Provide separate billing for the management applications for the consumer's resources

An organization wants to build a pilot cloud for developers to learn and practice cloud- native application design.

The organization expects that the cloud will host many tiny instances that will use few resources. What accurately describes the optimal CPU and memory configuration?

A. High CPU core count and high memory capacity

B. High CPU core count and moderate memory capacity

C. Moderate CPU core count and moderate memory capacity

D. Moderate CPU core count and high memory capacity

After developing prototype applications in the public cloud, developers determined that they want softwaredefined network functionality. Which ability will this requirement provide for the developers?

A. Programmatically provision an IPsec VPN tunnel between the public and private clouds

B. Programmatically migrate layer-3 access from aggregate to access switches

C. Programmatically control physical core network topologies

D. Programmatically provision physical network segments and services

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

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

A. Portal, catalog, and orchestration

B. Virtual networking, portal, and catalog

C. Orchestration, virtual networking, and portal

D. Catalog, orchestration, and virtual networking

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

During the assessment phase of the design process, the cloud architect discovers that an organization wants to provide consumers with the ability to backup and restore entire virtual machines. Which backup application functionality will support this requirement?

A. Agent-based backups

B. Image-based backups

C. Array-based snapshots

D. Cloud gateway backups

An organization has internal applications that require block, file, and object storage. They anticipate the need for multi-PB storage within the next 18 months. In addition, they would prefer to use commodity hardware as well as open source technologies. Which solution should be recommended?

A. Cinder

B. Hadoop

C. Swift

D. Ceph
