What is the key business goal when consolidating by business application? Your client is considering a virtualized data center (VDC) as an investment in process improvement. A VDC can improve the delivery of which business process? An organization supporting 10,000 desktop PCs is considering implementing VDI. What is a benefit of moving forward with a VDI plan? 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? Which EMC product provides seamless data mobility and enables management of the storage resources of multiple heterogeneous arrays from a single interface? Which feature allows for the maximum utilization of the I/O and bandwidth available in the network infrastructure? Which mode of IPSec encrypts the entire IP packet? What is IT's approach to addressing performance issues during the Operationalize phase of the Cloud Maturity Model? Why is there a need for a full risk assessment if a quick risk assessment has already been performed? A company is considering converting their VDC to IaaS. They realize to do this they will also have to implement several new technologies and create several new functions: service operations and service management. Previously the organization thought they were service oriented because they had a service desk in IT to provide support. Which key area(s) of investment is required for successful transition to IaaS? What are the four key areas reported on a scorecard used to compare the assessments of internal IT to Service Providers? Which framework for governance is also an international standard? In addition to hypervisor hardening, what are the components of a Tier 3 trust tier? A large company with multiple heterogeneous arrays would like to take advantage of the performance simplified management benefits of storage virtualization. They have a data center transformation pain that includes producing power and cooling at a high priority. Which storage virtualization method would meet their requirements? Why proper sizing of an in-bound network is based on storage virtualization configuration import? Your client is considering a virtualized data center (VDC) as an investment in process improvement. A VDC can improve the delivery of which business process? You have decided to pursue a "scale-out" approach instead of a "scale-up" approach to storage. What is the fundamental tradeoff that you have made? Your customer is primarily concerned with asset discovery and a reconciled view of all infrastructure components and the dependencies between them. Which type of architecture would you recommend? 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? 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? Which represent key legal contracts for a service provider? In which situation should you consider implementing hypervisor over-provisioning? Questions such as "How would you classify the sensitivity of your data?" and "What is the value of this application data?" are examples of which kind of sample risk score questions? A large banking customer has decided to move from a physical to virtual environment. They have been the long processes of gathering data from a storage perspective, what is something they could implement in the near term to help them transform to a virtual environment? From a virtualization capacity perspective, what are the top issues? Which is a scale-out NAS solution? A hypervisor running several virtual servers crashes, and all virtual servers are restarted on another hypervisor. When the applications restart, they replay log files to bring data up to date. Which type of consistency does this situation represent? What is a feature of the Cisco Unified Computing System (UCS)? A Linux-based application platform stack is downloaded from a community site. It is prepackaged to run on a specific hypervisor. The administrator must import it into the VDC environment, and then perform minimal configuration tasks. Once installed, the platform stack will solve a specific business problem for the organization. What is this an example of? Which technology provides load balancing and fault tolerance for Fibre Channel over Ethernet traffic? A customer wants to ensure that their critical application can fail over to another physical host within the cluster without disruption. Which feature should be utilized? Which is an example of a hypervisor that does binary translation of sensitive non-virtualized requests but allows for direct execution of user requests? The Patriot Act is a law that, under special circumstances, allows warrantless search and seizure of information. Which environment presents the highest risk to corporate information given the Patriot Act? An application is designed to use a middleware layer to communicate with, and share the data and resources of, other applications in the organization. What is this an example of? Which two capacity management objectives often conflict with each other? A VDC administrator wants to implement a service to non-disruptively relocate virtual machines from one physical host to another physical host. Which service should they implement? What is a key business driver for automation in the virtualized data center? What is (are) included in internal and external attestation? A company is planning the backup strategy for their virtual machine environment. They are considering migrating to an image based backup model. Where image-based backup would be processed in the environment? Which is primary dimension to consider when performing a risk management? A customer has asked you to develop a framework for assuming that the cloud Part of this will resume an assessment development. Where should you lock first for assessment criteria and technologies? A large enterprise is in the process of converting to a virtual data center as a first step toward cloud computing. They want the ability to deploy, manage, and decommission infrastructure components in a timely manner to meet their business requirements, with minimal impact to their systems administration staff. What should be implemented? As part of a VDC design, you configured a number of hypervisor clusters that require a non- routable network to accommodate data transfers for online VM migrations and cluster heartbeats. However, some of the clusters contain sensitive data that should not be accessible by hypervisors in any other cluster. The design recommends using Private VLANs to isolate each cluster's private network traffic. The network administrator has created a Primary VLAN, and asks you how the Private VLANs should be configured. How should you instruct the network administrator to proceed? An application processes test results from a manufacturing facility, then generates and archives quality reports. The application runs on an old, but still supported UNIX system. It was developed by an organization's IT department 10 years ago. While it has not been changed in over five years, the application source code and skills needed to modify it are still available internally. What is this an example of? You are planning to deploy a virtualized application in a high-availability configuration with automated VM restart on a hypervisor cluster. Your sizing estimates show that peak workload conditions will saturate the processing power of four hypervisor servers. To meet the SLA, N+2 redundancy is required on the hypervisor servers, with server utilization not to exceed 80% under any conditions. What is the minimum number of nodes that you should configure in the hypervisor cluster? A VDC application design dictates the use of multiple hypervisors with array LUNs that are directly provisioned to each VM. The application data has an active lifetime of 6 to 9 months, after which it is rarely accessed. The need is to re-purpose several storage arrays from different vendors and performance capabilities. Which technology should be considered for the VDC storage design? Which mode of IPSec encrypts only the payload of the IP packet? A company has to implement a test/dev environment infrastructure as quickly as possible. The company does not have weeks or months to accomplish this. They also have limited resources available. Considering their timeline, what type of infrastructure would the company most likely have to choose? Your client has a block-based storage virtualization environment. They want to avoid losing data in the event of double disk failure. Which technology do you suggest they deploy? A hypervisor running several virtual servers crashes, and all virtual servers are restarted on another hypervisor. When the applications restart, they replay log files to bring data up to date. Which type of consistency does this situation represent?
