  1. What is a VMware Validated Design? Comprehensive blueprints used to build a Software Defined Data Center with VxRail appliances

Explanation – https://community.emc.com/docs/DOC-66332

2. Which component of the Acropolis platform presents storage for use by the hypervisor? Controller VMs

Explanation – Description: Controller level metrics are pulled directly from the Nutanix Controller VMs and represent what the Nutanix front-end is seeing from NFS/SMB/iSCSI or any back-end operations (e.g., ILM, disk balancing, etc.).  This data can be viewed for one of more Controller VM(s) or the aggregate cluster. 

3. What defines the digitization process? Converting analog pieces of information into a digital format

Explanation – Digitization, less commonly digitalization, is the process of converting information into a digital (i.e. computer-readable) format, in which it organizes the information into bits. Digital Transformation is the use of new, fast and frequently changing digital technology to solve problems. One of the examples of digital transformation is cloud computing. It reduces reliance on user owned hardware and increases reliance on subscription based cloud services

4. VMAX storage solution supports? Data Protection, Replication, Encryption, NFS, ISCSI, FC, File, and Block.

Explanation – VMAX support these 8

5. What are the primary features of Vmware vSAN? Deduplication and Erasure Coding

Explanation – A primary goal of space efficiency features in Virtual SAN 6.2, was to close the cost per GB gap between flash and 10K RPM drives. We expect many customers to find that deduplication, compression and erasure coding, will enable a shift to all-flash Virtual SAN designs, providing a balance of performance consistency and cost. Erasure coding (EC) is a method of data protection in which data is broken into fragments, expanded and encoded with redundant data pieces and stored across a set of different locations or storage media.

6. XtremIO X2 solution supports? Deduplication, Compression, Data Protection, Encryption, iSCSI, FC and Block

8. In the Dell EMC Cloud for Microsoft Azure solution, what components are part of the Azure Scale Unit? Dell EMC PowerEdge Servers, Hardware Lifecycle Host, Management network switch

Explanation – This solution consists of modular building blocks called Scale Units (SU). An SU is a set of compute (servers), storage, and networking that represents a single unit, and an Azure fault domain. A scale unit contains the following components:

The Dell EMC hardware lifecycle host (HLH) enables monitoring and updates for Azure Stack. The HLH is a Dell EMC PowerEdge  management server with Dell EMC management software and tools to enable server and network monitoring,“call-home” capability, if required, and patch and update capability for the components that Dell EMC provides.

9. An organization is on a Digital Transformation journey. The business is adopting agile application development methodologies to respond to customer feedback more quickly and improve cloud native applications. The IT department recommends a Hybrid Cloud solution. What reason(s) would support this recommendation from IT? Distribute applications across geographies for better performance for consumers,Secure critical data within their data center for compliance reasons.

Explanation – Agile  = Different locations stand out for me and better performance across geographies make sense. Hybrid make sense for two reasons 1. Secure data with private cloud and 2. Cloud native for public cloud.

10. What is the minimum number of servers in a VxRack AS Scale Unit? 4

Explanation – Dell EMC ScaleIO (VxFlex OS) is software that creates a server-based SAN from the integrated Dell PowerEdge servers to deliver flexible and scalable performance and capacity on demand. ScaleIO combines storage resources to create a virtual pool of block storage with varying performance tiers. Its design enables you to scale from 4 nodes to over a thousand nodes.

11. An organization is developing cloud native applications. How should they distribute redundant services to minimize the impact of infrastructure outages? Across availability zones

Explanation – This is VSAN availability zones but there are others out there as well. An availability zone is a collection of infrastructure components. Each availability zone is isolated from other availability zones to prevent the propagation of failure or outage across the data center. An availability zone runs on its own physically distinct, independent infrastructure, and is engineered to be highly reliable. Each zone should have independent power, cooling, network, and security. Additionally, these zones should be physically separate so that even uncommon disasters affect only one zone.

12. What is an example of IaaS?

Amazon Elastic Compute Cloud (EC2)
Google Compute Engine
Microsoft Azure Compute

Explanation –

Infrastructure as a Service (IaaS) Capability for cloud consumers to provision infrastructure resources such as compute, network, and storage. Cloud consumers typically deploy and manage software, including operating systems and applications, within the provisioned infrastructure. Although consumers are provided with access to these resources, the cloud service provider maintains control of the underlying infrastructure that supports it. Examples: Amazon Elastic Compute Cloud (EC2), Google Compute Engine, Microsoft Azure Compute.

13. This is used as a centralized management platform for multiple VxBlock 1000 systems.

AMP-VX or
Advanced Management Platform

Explanation – The VxBlock System 1000 can be configured with up to 10 centralized storage systems including Dell EMC VMAXUnityPowerMaxIsilon, and XtremIO. The system is centrally managed by the Advanced Management Platform.

AMP-VX overviewManage multiple VxBlock Systems 1000 from a single, shared management platform using AMP-VX. Besides virtualization and compute components, AMP-VX contains a core set of management workloads to manage VxBlock 1000. Management tools are installed and configured on the AMP-VX. AMP-VX uses components and workloads to provide local management and management software to install and operate VxBlock 1000 components.

AMP-VX can rapidly adapt and respond to growing and changing management capabilities that Dell EMC supports. With AMP-VX, you can:

  • Run core and Dell EMC optional management workloads.
  • Monitor health and manage performance and capacity.
  • Provide network and fault isolation.

A VxBlock 1000 with an AMP-VX can centrally manage the following attached systems:

  • VxBlock System 340
  • VxBlock System 350
  • VxBlock System 540
  • VxBlock System 740

Central management of these platforms is an in-field consolidation service of AMP-2S managed Converged Systems. Central management requries assessment and sizing to verify that the additional AMP-2S workloads can be consolidated onto the AMP-VX. Core management VMs are migrated from the AMP-2S on each VxBlock System and consolidated onto the AMP-VX.

14. It is defined as an operator-assigned, functionally independent segment of infrastructure? Availability Zones

Explanation –  An availability zone is a collection of infrastructure components. Each availability zone is isolated from other availability zones to prevent the propagation of failure or outage across the data center. An availability zone runs on its own physically distinct, independent infrastructure, and is engineered to be highly reliable. Each zone should have independent power, cooling, network, and security. Additionally, these zones should be physically separate so that even uncommon disasters affect only one zone.

15. Match each VxBlock 1000 storage solution to the relevant feature.

16. What component must be configured when a VxBlock 1000 is used with an Isilon cluster? Cisco LAN switch

Explanation – Isilon uses LAN as it is a NAS. This will probably change in the future where Dell Technologies will start using their own switches like the started now with PowerOne in Nov 2019.

17. An organization wants to improve customer experience by designing applications that run in multiple clouds and that are closer to the customer. Which methodology should the organization adopt to achieve this goal? Cloud-native Application Development

Explanation – What are cloud-native applications?

Cloud-native applications are a collection of small, independent, and loosely coupled services. They are designed to deliver well recognized business value, like the ability to rapidly incorporate user feedback for continuous improvement. In short, cloud-native app development is a way to speed up how you build new applications, optimize existing ones, and connect them all together. Its goal is to deliver apps users want at the pace a business needs.

But what about the “cloud” in cloud-native applications? If an app is “cloud-native,” it’s specifically designed to provide a consistent development and automated management experience across private, public, and hybrid clouds. Organizations adopt cloud computing to increase the scalability and availability of apps. These benefits are achieved through self-service and on-demand provisioning of resources, as well as automating the application life cycle from development to production.

But to fully utilize these benefits, a new form of application development is needed.

Cloud-native development is just that—an approach to building and updating apps quickly, while improving quality and reducing risk. More specifically, it’s a way to build and run responsive, scalable, and fault-tolerant apps anywhere—whether in public, private, or hybrid clouds.

18. An organization wants to deploy applications across multiple locations around the world. They also want to maintain application up-time and continuously deliver updates to meet changing customer needs. The organization would also like to build applications faster and maintain consistency across applications. What should the organization adopt to meet their goals? Cloud-native application development and PaaS

Explanation – You really want to have a platform-as-a-service (PaaS) model. It makes things a lot easier. The vast majority of cloud customers start out with infrastructure-as-a-service (IaaS), which helps abstract their apps from the underlying hardware. But PaaS adds an extra layer to abstract the underlying OS, so you can focus entirely on the business logic of your app and not worry about making OS calls.

19. What is the main purpose of the ToR switches in a VxRack AS solution? Communication path for servers in a rack.

Explanation – The VxRack FLEX encompasses support for networking—both physical and virtual. Physical networking consists of a leaf-spine topology with top of rack (ToR) and spine switches. Each physical rack contains two ToR switches, which control network traffic and redundancy, and a management switch for out-of-band connectivity.

20. Why would businesses embrace Workforce Transformation? Enable employees to focus more on adding customer value

Explanation – Digital transformation starts with the customer. Businesses focus on improving the customer experience and providing value. As a result, businesses change their strategy, business models, and processes to provide a better customer value and use technology to accomplish this transformation. Along with digital transformation, the workforce, security, and IT must transform.

21. Why would an organization use a PaaS solution to build and deploy cloud native applications? Enables faster, more consistent development of applications using a common set of development tools and services

Explanation – Platform as a Service (PaaS) The capability for cloud consumers to deploy applications on cloud infrastructure using programming languages, tools, libraries, and other services provided and supported by the cloud provider. Consumers have control over the deployed applications and configurations, and providers maintain control over the infrastructure and operation systems.

Examples: Pivotal Web Services, Google App Engine, AWS Elastic Beanstalk

22. What is a feature of VxFlex OS? Encryption

ExplanationThere is no impact to VxFlex OS features, because encryption is performed before data is written to SDS devices. This ensures that the enterprise-grade data protection and resiliency provided by VxFlex OS are uninterrupted by the encryption process.

23. What contributes to lowered data center power and cooling costs? Enterprise Flash drives
