E20-018 Online Practice Questions and Answers

A small company has two data centers located 30 km apart. You have been asked to design a VDC in each of the two data centers, using stretched VLANs and native Fibre Channel extension to interconnect the environments. After inquiring with the local service providers, you find that only two strands of dark fiber are available.

Which distance networking technology is the most appropriate?

A. CWDM

B. DWDM

C. Dark Fiber

D. MPLS

Which feature allows for the maximum utilization of the I/O and bandwidth available in the network infrastructure?

A. VLAN tagging

B. VLAN grouping

C. Port grouping

D. Oversubscription

A company has finished the design for their VDC. They realize that they should also include a few design considerations to prepare them for cloud.

What is a key business reason for the company to build a cloud-based service?

A. Speed and agility

B. Cost savings

C. Multi-tenancy

D. Chargeback

Which technology provides fault tolerance and load balancing for FCoE traffic?

A. Multipathing Software

B. NIC Teaming

C. HBA Teaming

D. Fibre Channel Initiator

An organization plans to migrate a single application from a traditional, physical infrastructure to new servers. These servers are the first of several planned for their VDC. This will be the pilot application for the VDC migration to be completed over the next 5 years. The project is well funded and the VDC has more than enough capacity to support the pilot application.

Which migration strategy will they most likely use and why?

A. A forklift approach, because they can keep the old systems running in parallel and they have the capacity to run in either the VDC or traditional data center as needed should something go wrong.

B. A phased approach, because they can keep the old systems running in parallel and they have the capacity to run in either the VDC or traditional data center as needed should something go wrong.

C. A forklift approach, because this allows them to re-purpose the old servers and add those resources to the new VDC immediately.

D. A phased approach, because this allows them to re-purpose the old servers and add those resources to the new VDC immediately.

You are designing a VDC that uses converged networking to support both LAN and SAN traffic. FCoE is used exclusively for storage access. The access and aggregation layer switches that have been chosen support both 10 and 40 Gigabit Ethernet and Data Center Bridging.

You have determined that the traffic between the access layer and aggregation layer switches is:

-

Average SAN (FCoE) –60 Gb/s

-

Average LAN (Ethernet) –100 Gb/s

-

Burst SAN (FCoE) –80 Gb/s

-

Burst LAN (Ethernet) –130 GB/s Performance cannot be degraded due to a failure of a single switch. Which port configuration would support the average traffic between the access and aggregation layer

switches?

A. Three 40 Gb/s ports and six 10 Gb/s ports

B. Four 40 Gb/s ports

C. Three 40 Gb/s ports and four 10 Gb/s ports

D. Four 40 Gb/s ports and eight 10 Gb/s ports

A company has five heterogeneous storage arrays that are all connected to a common SAN environment.

They want to offer storage to their end users, masking the identity of the target storage so the users cannot

tell which storage system they are using.

Which virtualization technique would work in this environment?

A. Distributed virtualization

B. Block-level storage virtualization

C. Hadoop HDFS

D. File-level storage virtualization

An application processes test results from a manufacturing facility, then generates and archives quality reports. The application runs on an old, but still supported UNIX system. It was developed by an organization's IT department 10 years ago. While it has not been changed in over five years, the application source code and skills needed to modify it are still available internally.

What is this an example of?

A. A legacy application

B. Vendor lock-in

C. An enterprise application

D. Service-oriented architecture

What is typically included with an IaaS bundle featuring compute, storage, and networking?

A. Encryption technology

B. Management tools

C. Integrated development environment

D. Storage virtualization

A development organization uses a PaaS service from a public cloud to develop and test an application. Once sending and verification are complete, the development team discovers that the cloud services uses proprietary software in the PaaS clustering mailing and deployment of the application within their production data center imposition without significant application records.

What this type of lock-in called?

A. Geographical lock-in

B. Technology lock-in

C. Cloud lock-in

D. Vendor lock-in

Which is a valid method for modifying an application environment to support more clients and increased data throughput?

A. Vertically scale by increasing resources on existing nodes

B. Migrate the application from SSD to SAS storage

C. Migrate the application from SAS to NL SAS storage

D. Horizontally scale using a closed loop system

A developer has asked you to recommend a Cloud Service Model to run a new home grown application currently in deployment. The application is based upon a programming language that your IT staff has no experience in supporting.

Based upon these requirements, which cloud model would you recommend?

A. WaaS

B. SaaS

C. PaaS

D. IaaS

An organization seeks to solve a business problem by licensing software from a supplier. The supplier contract stipulates that the software will only be supported if it runs on server platforms also provided by that supplier.

What is this an example of?

A. A virtual appliance

B. A legacy application

C. Enterprise Application Integration

D. Vendor lock-in

The CIO has asked you to review the status of your company's cloud deployment and validates that the implementation has entered the IT-as-a-Service phase.

Which capability must be in place to transmitting to this phase?

A. Self-service

B. Policy-driven automation

C. Chargeback

D. Zero-touch Infrastructure

A company is considering converting their VDC to IaaS. They realize to do this they will also have to implement several new technologies and create several new functions: service operations and service management. Previously the organization thought they were service oriented because they had a service desk in IT to provide support.

Which key area(s) of investment is required for successful transition to IaaS?

A. A chargeback/showback method for showing value back to the business

B. ITIL-based, standardized service templates

C. An expanded help desk that includes more comprehensive reporting

D. Service level agreements with the lines of business
