What is an accurate statement about VLANs and VSANs in an FCoE environment with an existing FC SAN?
A. A dedicated VLAN must be configured for each VSAN
B. VLANs configured for VSANs must carry regular LAN traffic
C. Default VLAN must map to all VSANs defined in the FCoE switch
D. A minimum of four VLANs must be created to isolate VSAN traffic
What is a benefit of N_Port virtualization (NPV)?
A. Reduces the number of domain IDs in a fabric
B. Eliminates the overhead of fabric services in an FC SAN
C. Enables online expansion of virtual volumes
D. Allows an N_Port to transfer multiple VSAN traffic
An organization plans to deploy a new application in their environment. The new application requires 3 TB of storage space. During peak workloads, the application is expected to generate 2450 IOPS with a typical I/O size of 2 KB. The capacity of each available disk drive is 500 GB. The maximum number of IOPS a drive can perform at with 70 percent utilization is 90 IOPS.
What is the minimum number of disk drives needed to meet the application's capacity and performance requirements given a RAID 0 configuration?
A. 6
B. 16
C. 25
D. 28
What is a characteristic of software-defined networking?
A. Abstracts and separates the control plane from the data plane
B. Data plane sends instructions to the control plane to handle network traffic
C. Controller in network switches takes over data plane functions
D. External software combines both data plane and control plane functions
What is a benefit of link aggregation in a SAN?
A. Provides a higher throughput than a single interswitch link can provide
B. Distributes the network traffic across all virtual SANs, ensuring even virtual SAN utilization
C. Optimizes performance by consolidating all interswitch links into a single physical link
D. Provides the flexibility to deploy the same interswitch links for both FC and iSCSI traffic
What maps the logical path of a file system to its physical path in a file-level virtualization implementation?
A. Global namespace
B. Remote procedure call
C. Distributed file system
D. Cache coherency
What provides the ability to automatically relocate extents across physical storage drives over the entire pool when new drives are added to the pool?
A. Storage pool rebalancing
B. Extent relocation
C. Storage pool tiering
D. Automated extent tiering
In which data access method does the file system access an iSCSI storage system over a network?
A. Block-based
B. File-based
C. Object-based
D. Sector-based
