EMC E20-018 Online Questions & Answers

• Question 301:

  Refer to the exhibit.

  

  You are configuring the SAN environment of a VDC using switches with a Switch on a Chip architecture. A high I/O hypervisor is connected to Port 1 on the switch. Where should you make the ISL connection to provide the lowest latency?

  A. Port 4
  B. Port 5
  C. Port 8
  D. Port 20
  A. Port 4

• Question 302:

  Refer to the exhibit.

  

  A VDC architect has acquired switches to be used as converged access layer switches. All Fibre Channel traffic operates at 8 Gbps and

  all ports operate at line-rate. All the FC ports will be configured as ISLs and be connected to the SAN core switches. An equal number of converged ports will be configured as standard Ethernet ports and connected to the aggregation layer

  switches.

  What is the expected oversubscription ratio of the FC ports on

  this switch?

  A. 3:1
  B. 5:1
  C. 6:1
  D. 8:1
  B. 5:1

• Question 303:

  A hypervisor has been deployed with all virtual machines (VMs) sharing the same storage array LUN for their respective virtual disks. Array-based replication has been implemented for BC/DR. A restore of a single VM is now required. What would happen if you attempt to recover an individual VM?

  A. All VMs will be reverted.
  B. Only the restored VM will need to be restarted.
  C. None of the VMs will be restartable.
  D. Only the restored VM will be reverted.
  A. All VMs will be reverted.

• Question 304:

  What are the two primary reasons for creating services in the service catalog?

  A. Standardization, providing consumers with business relevant options
  B. Standardization, providing consumers with templates for selection
  C. Setting prices, limiting resource consumption
  D. Setting prices, deploying security policies
  A. Standardization, providing consumers with business relevant options

• Question 305:

  Which backup solution(s) are possible candidates when there is a need to restore specific files on a VM?

  A. VM-based backup and image-based backup
  B. Storage-based backup only
  C. Hypervisor-based ("VM as flat file") backup
  D. Storage-based backup and image-based backup
  A. VM-based backup and image-based backup

• Question 306:

  An application is used by nearly all the employees in an organization to place and track orders, provide customer support, maintain and report on financials, and track product defects.

  The application was written by the organization's IT Department 10 years ago. The IT staff actively maintains it and adds features on a regular basis.

  What is this an example of?

  A. Vendor lock-in
  B. A legacy application
  C. An enterprise application
  D. Service-oriented architecture
  C. An enterprise application

• Question 307:

  The formula "If A > B and B > C, then A > C" describes which aspect of governance, compliance, and risk in a cloud architecture?

  A. Transitivity of risk
  B. Governance priority weighting
  C. Compliance tiering
  D. Effective risk mitigation
  A. Transitivity of risk

• Question 308:

  Refer to the exhibit.

  

  You are designing the storage environment for a new VDC. The applications have been classified into three groups, as shown in the exhibit. You have chosen to create a storage pool for each application group. How should you configure the storage for each pool to meet the performance and capacity requirements, while minimizing costs?

  A. Pool 1 - SSD and SAS drives with storage tieringPool 2 - SAS and NL SAS drives with storage tiering and cache tieringPool 3 - SAS and NL SAS drives with storage tiering and cache tiering
  B. Pool 1 - SSD and SAS drives with storage tieringPool 2 - SSD and NL SAS drives with storage tieringPool 3 - SAS drives with cache tiering
  C. Pool 1 - SSD and SAS drives with storage tieringPool 2 - SAS and NL SAS drives with storage tiering and cache tieringPool 3 - NL SAS drives with cache tiering D. Pool 1 - SSD and SAS drives with storage tiering and cache tieringPool 2 - SAS and NL SAS drives with storage tiering and cache tieringPool 3 - NL SAS drives with cache tiering
  C. Pool 1 - SSD and SAS drives with storage tieringPool 2 - SAS and NL SAS drives with storage tiering and cache tieringPool 3 - NL SAS drives with cache tiering D. Pool 1 - SSD and SAS drives with storage tiering and cache tieringPool 2 - SAS and NL SAS drives with storage tiering and cache tieringPool 3 - NL SAS drives with cache tiering

• Question 309:

  You have decided to pursue a "scale-out" approach instead of a "scale-up" approach to storage. What is the fundamental tradeoff that you have made?

  A. Complexity of management versus limited scalability
  B. Improved availability versus unlimited scalability
  C. Higher application throughput versus degraded response time
  D. Ease of storage tiering versus unpredictable performance
  A. Complexity of management versus limited scalability

• Question 310:

  What is its approach to addressing performance issues during the Virtualize phrase of the cloud maturity mode?

  A. Selective
  B. Investigative
  C. Proactive
