Cisco 646-985 Online Questions & Answers

• Question 71:

  You are describing to your customers how much the potential financial savings would be if they have virtualized network services modules. Which one of the following statements is suitable?

  A. Virtual services modules can support up to a maximum of four virtual contexts, so they can save up to 75 percent of both power and rack space.
  B. The savings will depend upon the requirements for each data center but can be as much as 80 percent on power and 30 units of rack space.
  C. Because the services are virtual, virtual network services modules will take up no rack space and will consume no power.
  D. Every time a new virtual context is created, the services modules draw 50 percent more power than a single-context operation, so the maximum number of virtual contexts is limited to four per module. With the maximum of four virtual contexts, the total power consumed is 250 percent of a single context operation, which is 150 percent less power than four physical service appliances would draw.
  B. The savings will depend upon the requirements for each data center but can be as much as 80 percent on power and 30 units of rack space.

• Question 72:

  You are familiar with both the traditional network sales cycle and the data center sales cycle. What is the main difference between the two?

  B. A data center sales professional should use the customer's network team to advise him when best to get involved in the sales cycle.
  C. A data center account manager requires more technical skills than commercial skills.

  B. When deploying FCoE, Data Center Ethernet is superior to traditional Ethernet.
  D. Using FCoE as part of a data-center-wide connectivity strategy is being promoted by Brocade as well as Cisco.

• Question 75:

  You are required to describe the traditional trend of cost of a data center solution in its lifetime to your customer. Which statement is making sense?

  A. CapEx and OpEx both decrease after initial purchase and deployment of the solution.
  B. CapEx is initially low but rises over time because of the need for more hardware.
  C. CapEx and OpEx both increase over time as the scale of the solution grows.
  D. OpEx steadily increases over time because of rising maintenance costs.
  D. OpEx steadily increases over time because of rising maintenance costs.

• Question 76:

  Your customer seems to show great interest in support for Network-Accelerated Server less Backup (NASB). Which option is it suitable for you to recommend him to use?

  A. Cisco ACE XML Gateway
  B. Cisco MDS SSM module
  C. a dedicated backup SAN for redundancy
  D. a 56-port Layer 2 fabric extender

• Question 78:

  Which statement is correct when contrasting the Brocade LSAN and the Cisco VSAN?

  A. The Brocade LSAN is a next-generation version of the Cisco VSAN.
  B. The Cisco VSANs and the Brocade LSANs are basically the same concept.
  C. The Cisco VSAN can allow a single physical fabric to be logically segmented; the Brocade LSAN needs physically separated fabrics.
  D. The Cisco VSAN delivers security between environments by creating multiple physical fabrics, while Brocade's LSAN allows a single physical fabric to be logically segmented and, as a result, compromises security between environments.
  C. The Cisco VSAN can allow a single physical fabric to be logically segmented; the Brocade LSAN needs physically separated fabrics.

• Question 79:

  It is possible for a user to run Cisco storage networking solutions in cooperation with his Brocade and legacy McData switches. It is supported by what feature?

  A. Line card expansion modules may have Fibre Channel ports, 10 Gigabit Ethernet ports, or a combination of both to accommodate switches from other vendors.

  C. Interoperability modes allow VSANs to be propagated from the Cisco MDS to other Fibre Channel devices.
  D. Because Fibre Channel is based on a set of open standards, Cisco solutions are fully compatible with other Fibre Channel devices.
  C. Interoperability modes allow VSANs to be propagated from the Cisco MDS to other Fibre Channel devices.

• Question 80:
