A VDC environment will be deployed with several virtual machines (VMs). The datastores for the VMs will be hosted on a storage array. Array-based local replication has been proposed as the BC/DR solution. Restore granularity will be at the individual VM level.
What is the simplest data layout that would meet this requirement?
A. A single large LUN for all virtual disks
B. An individual LUN for all virtual disks of each VM
C. All virtual disks on the boot LUN of the hypervisor
D. An individual LUN for each virtual disk
A company moved to a new building that contains a fully virtualized data center. They purchased a building 10 km away and decide to build a second data center at that location. The new data center will be identical to the first, and applications and services will be mobile between the locations.
Which WAN connectivity option would provide both the best performance for virtual server mobility across sites?
A. MPLS
B. Dark Fiber
C. IP
D. WDM
Your VDC design calls for iSCSI adapters. In a meeting with the CIO, you are challenged about the planned capital expenditure for the iSCSI adapters. The CIO states that it would more cost-effective to purchase 10 Gigabit Ethernet NICs and use the integrated hypervisor software stack.
What effect will this have on the hypervisors?
A. Increased CPU load
B. Increased amount of I/O
C. Decreased amount of I/O
D. Decreased CPU load
You have decided to pursue a "scale-up" approach instead of a "scale-out" approach to storage.
What is the fundamental tradeoff that you have made?
A. Simplicity of management versus improved scalability
B. Improved availability versus limited scalability
C. Ease of storage tiering versus poor resource utilization
D. Higher application throughput versus degraded response time
A. Disaster recovery
B. Information security
C. Management
D. Business
Which EMC system enables management of the storage resources of multiple heterogeneous arrays from a single interface while providing seamless data mobility?
A. VPLEX
B. Vblock
C. VNXe
D. Atmos
A company asks you to design a stretched cluster environment for their new hypervisor deployment. The company's two data centers are located 150 km apart, and have Fibre Channel connected hosts and storage at both locations.
Which distance networking technology should you recommend?
A. DWDM
B. CWDM
C. Dark Fiber
D. MPLS
An organization with 25,000 employees has moved to a new building that contains a fully virtualized data center with a virtual desktop infrastructure (VDI) instituted for all employees. However, each morning between 9:00 am to 9:30, the help desk receives a large number of calls concerning slow performance and timeout issues.
The IT department that the storage array's Fibre Channel drives is the bottleneck. They propose sold purchasing solid state disks (SSDs) to store the entire VDI environment. Unfortunately, their proposed is rejected because of the cost of the drives.
Which array feature should the organization implement to reduce the quality of SSD that are required to service the high I/O bursts of their VCs environment?
A. Thin Pools
B. Deduplication
C. Cache Tiering
D. Cache Partitioning
Which type of switch can provide management functions for virtual machine ports?
A. Distributed virtual switch
B. Standard virtual switch
C. Physical switch
D. Third-party virtual switch
You are designing a new VDC and are planning to use iSCSI for storage connectivity from the hypervisors. The network infrastructure is 10 Gigabit Ethernet, and the hypervisor hardware can support only two NICs. Your networking design on the hypervisor must provide the highest level of performance, security, and fault tolerance.
What should you recommend?
A. Bond the NICs together and connect them to different access layer switches. Configure a separate VLAN for the iSCSI traffic.
B. Leave the NICs independent and connect them to different access layer switches. Configure a separate VLAN for iSCSI traffic on each NIC.
C. Bond the NICs together and connect them to different access layer switches. Use the same VLAN for SCSI traffic as for management traffic.
D. Leave the NICs independent and connect them to different access layer switches.Use the same VLAN for SCSI traffic as for management traffic.
