An architect is designing a VDC network environment, and is concerned about the overhead introduced by the Spanning Tree Protocol. The environment will have approximately 2,500 VLANs configured.
Which Spanning Tree Protocol should the architect specify for this implementation?

• A.RSTP
• B.STP
• C.MSTP
• D.PVST

A large enterprise has introduced virtualization into a data center. During live Mitigation, several virtual hosts have recognized lost cluster heartbeats and network performance degradation.
Which solution should be implemented to immediate the solution?

• A.Implement isolated VLAs to separate management control traffic from production traffic
• B.Implement load balance on the HBA to improve overall host performance
• C.Implement load balancing on the NICs to improve overall host performance
• D.Implement a distributed virtual switch to separate the data plane from the control plane on the NIC

Which is an example of vertically scaling a virtual application?

• A.Cluster two database virtual servers across two physical servers
• B.Migrate a database virtual server to a higher-capacity physical server
• C.Migrate a database virtual server to a less-utilized physical server
• D.Cluster two database virtual servers on a single physical server

Refer to the exhibit.

A VDC design requires 300 blade server chassis, each with two embedded Fibre Channel switches, which are connected to two separate SAN fabrics. For ease of management, each fabric can only be configured with a single VSAN.
How should you configure this environment to meet the requirements?

• A.Configure the blade server switches in NPIV mode. Configure the SAN core switches in NPV mode.
• B.Configure the blade server switches in NPV mode. Configure the storage edge switches in NPIV mode.
• C.Configure the blade server switches in NPIV mode. Configure the storage edge switches in NPV mode.
• D.Configure the blade server switches in NPV mode.
  Configure the SAN core switches in NPIV mode.
