EMC EMC Specialist E20-018 Questions & Answers

• Question 271:

  What is a benefit of client-side application virtualization?

  A. Ease of license tracking, assignment, and management is achieved.

  B. Reduced overall complexity in the application and desktop environment is achieved.

  C. Tools used to manage standard applications can also be used to manage virtualized client-side applications.

  D. All applications can be virtualized, providing flexibility and management control of client- side applications.

  Correct Answer: D

• Question 272:

  In the CAP Theorem, what is Partitioning?

  A. Ability to maintain ACID properties or transactions

  B. Ability to respond to all requests successfully

  C. Ability to maintain BASE properties or transactions

  D. Ability to handle lost network connectivity gracefully

  Correct Answer: D

• Question 273:

  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

  Correct Answer: A

• Question 274:

  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

  The port channeling technology you are using requires that channels be configured with even numbers of links. Performance cannot be degraded due to a failure of a single switch.

  Which port configuration would support the average and burst traffic between the access and aggregation layer switches?

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

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

  C. Six 40 Gb/s ports

  D. Six 40 Gb/s ports and two 10 Gb/s ports

  Correct Answer: B

• Question 275:

  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

  Correct Answer: D

• Question 276:

  Refer to the exhibit.

  

  You are expanding the compute layer of a VDC, and need to add more access layer switches to provide connectivity to the hypervisors. However, there are no available ports on the two aggregation layer switches to accommodate the uplink connections from the new access layer switches, and there is no available funding to purchase additional aggregation layer switches. The active uplinks are operating at 95% of capacity.

  What can be done to expand the access layer and not impact the performance of the existing environment?

  A. Aggregate the aggregation layer switches into a virtual switch. Reduce the number of uplink connections from each access layer switch by 50%.

  B. Aggregate the access layer switches into a virtual switch. Reduce the number of uplink connections to each aggregation layer switch by 50%.

  C. Aggregate the datacenter core switches. Reduce the number of uplink connections from each access layer switch by 50%.

  D. Aggregate the datacenter core switches. Reduce the number of uplink connections from each aggregation layer switch by 50%.

  Correct Answer: A

• Question 277:

  What can the consumer manage and control when subscribing to cloud Software as a Service (SaaS)?

  A. OS settings

  B. Network settings

  C. Application settings

  D. API module

  Correct Answer: C

• Question 278:

  Which application virtualization architectures usually require the use of a packager to prepare the application for deployment?

  A. Streaming, presentation

  B. Thick install, thin install

  C. Presentation, thick install

  D. Thin install, streaming

  Correct Answer: D

• Question 279:

  What is the primary mechanism used to secure data between data centers?

  A. IPSec

  B. SSL

  C. TLS

  D. FC-SP

  Correct Answer: A

• Question 280:

  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

  Correct Answer: A
