Which Fibre Channel SAN topology maximizes performance and expandability? A. arbitrated loop B. multi-point C. point-to-point D. switched fabric Answer: D Question: 21 What MDS 9000 feature provides more efficient SAN utilization by creating hardware-based isolated environments within a single physical SAN infrastructure? A. VSAN B. port channel C. SPAN D. trunking Answer: A Question: 22 Recently, in a new data center, a customer has used many Cisco MDS 9509 Multilayer Directors. In the process of deployment, it was found out that 110V AC power circuits had been installed instead of the high-voltage 220V AC circuits that had been ordered. The customer made a decision to install one of the directors and deploy the 110V AC circuit. The MDS 9509 is configured with two 2500W AC power supplies. The power supplies are configured in redundant mode. In this scenario, for the following items, which is the redundant power capacity of the MDS 9509? A. 1300 B. 5000 C. 2500 D. 2600 Answer: A Question: 23 Which three characteristics of Fibre Channel switch are unique to Cisco's MDS 9000 Series switches? (Choose three.) A. LUN Zoning B. Read-Only Zones C. Internet-Switch Link D. Fibre Channel Congestion ControlF Answer: A, B, D Question: 24 A customer has 80% of the total storage space directly connected to servers. The storage space needs are growing at 50% per year. Given these facts, which solution is recommended? A. server consolidation B. storage expansion C. storage consolidation D. increase in server capacity Answer: C
