EMC EMC Other Certification DES-2T13 Questions & Answers

• Question 11:

  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

  Correct Answer: B

  An overlay network is a computer network that is built on top of another network. Nodes in the overlay network can be thought of as being connected by virtual or logical links, each of which corresponds to a path, perhaps through many

  physical links, in the underlying network. Virtual overlay networks use tunneling protocols to extend isolated network segments between servers for multi-tenant data center networks.

• Question 12:

  An organization wants to have showback capability in their private cloud. Which cloud management platform component should be included in the cloud design to support this requirement?

  A. SSO

  B. Service catalog

  C. Metering application

  D. Monitoring application

  Correct Answer: C

  Note: IT chargeback is an accounting strategy that applies the costs of IT hardware, software, cloud services or shared services to the business unit in which they are used. IT showback is similar to IT chargeback, but the prices are for

  informational purposes only and no one is billed.

• Question 13:

  Which authentication and authorization feature is critical for service providers when supporting multi-tenancy?

  A. Integration with external authentication services

  B. Integration with external directory services

• Question 14:

  Case 1

  Refer to the exhibit.

  

  Your company recently negotiated several contracts with new customers to use its proprietary eCommerce system. As a result, the customer base has grown rapidly, which has introduced several challenges and requirements.

  Business requirements:

  Applications need to scale quickly

  Metrics and reporting to anticipate business trends and efficient use of resources External customers are looking to license the eCommerce application Other considerations:

  Applications need to be recorded for the public cloud Address security vulnerabilities for customer data in the cloud Refer to Case 1.

  You are sizing the compute capacity of blade servers in a converged infrastructure solution with the following specifications:

  Number of cores: 16

  Processor speed: 3.5 GHz

  Utilization percentage: 75%

  What is the total GHz processing capability of one blade server?

  A. 18,6

  B. 20,2

  C. 42,0

  D. 56,7

  Correct Answer: C

• Question 15:

  If the metering tool supports multi-tenancy and integrates with the cloud portal, what should be considered?

  A. Only permit local user access for security reasons

  B. Metering tool should not integrate with tenant authentication

  C. Metering server access should be allowed for all tenants

  D. Role-based access for security reasons

  Correct Answer: D

  The cost of collecting the metrics, and the balance between the value they provide and the impact on application operation. If metering code cannot be incorporated into existing components or roles, and you need to increase the number of

  instances of components or roles just to carry out metering, you might increase costs beyond the savings or income available from metering.
