EMC Virtualized Data Center and Cloud Infrastructure Design Specialist Sample Questions:
1. An organization uses Linux desktops, laptops, and servers for their primary infrastructure. The company has a business need to run an application that is only available for the Microsoft Windows operating system. This application needs to be available to approximately one third of their 100 desktop and laptop users.
There is concern about the stability of the application and how a single failure might impact multiple users in a shared environment.
Which solution would best meet their needs, and why?
A) RDS, because it allows all users to share a single instance of an application
B) VDI, because it provides the highest density per user
C) RDS, because it provides better fault tolerance
D) VDI, because it provides true user segmentation
2. You are meeting with the CIO to discuss your VDC design. They the amount of capital that is being invested in iSCSI adapters. They state that, because of the number of adapters required, it is 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) Decreased CPU load
B) Increased CPU load
C) Decreased amount of I/O
D) Increased amount of I/O
3. As part of a VDC design, you configured a number of virtual machine OS clusters. Each cluster must have a non-routable network to accommodate system heartbeats. However, some of the clusters house sensitive data that should not be accessible by any other cluster. For fault tolerance purposes, the cluster nodes will never be hosted on the same hypervisor.
How should you instruct the administrator to configure the Private VLANs?
A) Configure the Primary and Isolated VLANs on the hypervisor virtual switches.
B) Configure the Primary and Isolated VLANs on both the hypervisor virtual switches and access layer switches.
C) Configure the Primary and Community VLANs on both the hypervisor virtual switches and access layer switches.
D) Configure the Primary and Community VLANs on the hypervisor virtual switches.
4. 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. Use the same VLAN for SCSI traffic as for management traffic.
B) Bond the NICs together and connect them to different access layer switches. Configure a separate VLAN for the iSCSI traffic.
C) Leave the NICs independent and connect them to different access layer switches. Configure a separate VLAN for iSCSI traffic on each NIC.
D) Leave the NICs independent and connect them to different access layer switches. Use the same VLAN for SCSI traffic as for management traffic.
5. What are the three general components of a Vblock?
A) Caching, sub-LUN tiering, FAST
B) Multi-tenancy, self-service, elasticity
C) Compute, connectivity, storage
D) Security, risk, compliance
