2 Examsheets QUESTION 1 Which server would be a better fit for a customer who wants to increase both performance and the capacity for demanding virtualization and large data-set workloads? A. Cisco UCS C250 B. Cisco UCS C200 C. Cisco UCS C210 D. Cisco UCS C460 Correct Answer: D QUESTION 2 Which operational effect does the Cisco UCS "stateless server" deployment model bring to the customer? A. The server administrator can combine the resources of multiple servers. B. It enables easier and faster repurposing of servers. C. Server deployment can be optimized from a power perspective. D. It requires more administrative work on first server deployment. The stateless computing service allows existing software stacks to be migrated to any available discrete server within the system by creating and deploying what is known as a service profile exactly recreating the discrete system from which the workload migrated. A Unified Computing System server can also be pre-provisioned using service profiles to prepare it for a new application to be mounted. This can be used to not only rapidly provision servers, but also to reprovision servers as they are deployed and redeployed from one application type to another. A service profile is a self-contained logical representation (object) of a desired physical server, including connectivity, configuration, and identity. Each service profile serves a specific purpose, ensuring that the associated server hardware has the configuration, identities, and connectivity to the LAN and SAN based on the requirements from the applications the server will host. The service profile maintains configuration information about the server hardware, interfaces, fabric connectivity, and server and network identity: the server personality. This includes all of the unique information for the server, including the MAC, WWPN, UUID, boot order, and so forth. The personality information is stored in a format that can be managed through the Cisco UCS Manager. All service profiles are centrally managed and stored in a database on the Fabric Interconnects. This dynamic provisioning allows for complete infrastructure repurposing. QUESTION 3 What are the three steps to follow to engage a potential Cisco Unified Computing System customer with a qualified Cisco solution? A. Review the needs of the client. B. Create a client profile. C. Confirm the strategy.

(Choose three.) A. access B. consolidation C. switch D. distribution (aggregation) E. core F. server Correct Answer: ADE Cisco models architectural design on a simple model of core, aggregation, and access. This model is conceptual and can be applied to a physical architecture. The core of the network should be the most stable, provide the fastest bandwidth possible, and make flow decisions based on a number of criteria including physical and virtual location. The aggregation layer aggregates switches, isolates failure domains, interconnects campus resources, and connects branch and WAN networks. The server and storage access layer is how servers and storage devices gain access to resources such as SANs, high-performance clusters and grids, and the IP network. QUESTION 5 Which three specifications are considered to be architectural and mechanical specifications of a data center? (Choose three) A. unauthorized access B. available space C. load capacity D. fire suppression E. resilience F. cooling capacity CF

4 Multiple aspects of a Data Center need to be taken into account when its constructed. The architectural and mechanical specifications define how much space is available, how much load a floor can bear, the power capacity available for Data Center deployment, the available cooling capacity, and the cabling infrastructure type and management: - Available space - Load capacity - Power capacity, QUESTION 6 What are three service categories that are often found in cloud computing solutions? (Choose three.) A. Software-as-a-Service B. Storage-as-a-Service C. Platform-as-a-Service D. Infrastructure-as-a-Service E. Security-as-a-Service F. IP Communications-as-a-Service Correct Answer: ACD There are three major cloud computing service models: - Software as a Service (SaaS) - Platform as a Service (PaaS) - Infrastructure as a Service (IaaS) QUESTION 7 Which server setup would be the most suitable for a customer who is deploying server and desktop virtualization?

The second is a standalone physical or virtual appliance that is responsible for the configuration and management of the Nexus 1000V and the integration with VMware vcenter. QUESTION 19 What are typical CapEx and OpEx reductions that can be achieved with Cisco Unified Computing A. 40% and 50% B. 20% and 30% C. 10% and 20% D. 30% and 40%

9 While each customer environment is unique, customers are reporting CapEx reductions of 20 percent or more, and OpEx reductions in a wider range, depending on how aggressively they move to take advantage of advanced features of the Cisco QUESTION 20 A customer requires scalable server connectivity with multiple adapters for a VMware virtualizedserver environment. Which solution best addresses these requirements? A. Use servers with multiple Ethernet NICs and iscsi for shared storage access. B. Use Cisco C-Series servers with a Cisco UCS P81E Virtual Interface Card C. Use servers with multiple Ethernet NICs for UN and multiple FC HBAs for SAN connectivity. D. Use servers with two 10GE NICs and NFS for shared storage access. The Cisco UCS VIC M81KR Virtual Interface Card is a type of adapter, or mezzanine card, available in a Cisco UCS blade server that directly supports virtualization. It supports NIC virtualization for either a single operating system or for VMware ESX. Inside a single operating system, each VIC is presented as a physical adapter. For VMware, a special feature allows the VIC to be presented directly to the guest operating system, bypassing the VMware virtual switch layer. This allows efficiency and also allows the Cisco UCS to reconfigure network infrastructure if virtual machines migrate between ESX server instances on different blade servers. The UCS M81KR Virtual Interface Controller (VIC) for the Unified Computing System blade series has now been complemented by the UCS P81E Virtual Interface Card for use with Cisco UCS C-Series Rack-Mount Servers.

By providing a virtual machine-aware network to a virtual machine, Cisco VN-Link increases infrastructure, agility, improves application availability, strengthens security and compliance, and simplifies management. QUESTION 22 What is the current approach to the data center computer architecture scalability? A. scale in B. scale out

10 C. scale down D. scale up Correct Answer: A As the data center computing architecture evolves toward a scale-in approach, server scalability challenges must be addressed. Each server has a limited amount of resources in terms of processor, memory, or I/O throughput. Depending on resource availability, a server can run either one or several applications. Regardless of the server power and resource capacity, eventually these limitations are reached. Furthermore, not every server type is optimal for different applications. The question becomes, then, how do we increase the data center's computing power? QUESTION 23 How can using Cisco Application Networking Solutions help customers? A. improves service content B. reduces CapEx C. reduces security breaches D. improves service reliability Correct Answer: D Cisco has two main categories of Application Networking Solutions. Data center solutions provide secure, reliable, high-performing data center infrastructure for application traffic within or across data centers. Branch office and WAN solutions provide LAN-like performance for applications delivered over the WAN, and thus enable IT to consolidate servers/storage within the branch office. Cisco branch solutions for application delivery are deployed symmetrically in both the data center and branch offices. QUESTION 24 A customer wants to deploy more efficient switching for the VMware vsphere platform. Which of these shouldbe proposed as a solution? A. Deploy server blades in a single chassis B. Use a Cisco UCS VIC M81KR mezzanine card. C. Use only 10GE connectivity. D. Deploy servers with a large amount of memory. The Cisco UCS VIC M81KR Virtual Interface Card is a type of adapter, or mezzanine card, available in a Cisco UCS blade server that directly supports virtualization. It supports NIC virtualization for either a single operating system or for VMware ESX. Inside a single operating system, each VIC is presented as a physical adapter. For VMware, a special feature allows the VIC to be presented directly to the guest operating system, bypassing the VMware virtual switch layer. This allows efficiency and also allows the Cisco UCS to reconfigure network infrastructure if virtual machines migrate between ESX server instances on different blade servers. QUESTION 25 What is the function of the Cisco ACE service module?

11 A. Based on type of content, it effectively selects the site that will process the request. B. Based on type of content, it performs effect load balancing across the serves in the data center. C. Based on available bandwidth, it performs effect load balancing across the serves in the data center. D. Based on priorities, it effectively selects the server that will process the request. Here, the load balancing across servers, based on the content of the data passing through the network, is handled by Cisco s ACE Service Module. QUESTION 26 Which component represents the highest cost in an IT environment over time? A. CapEx B. ROI C. OpEx D. TCO Correct Answer: C Another factor is the operational cost of deploying and redeploying resources between application environments. Often, the acquisition and deployment of new assets is a less costly option, which effectively substitutes capital expenditure (CapEx) for operational expenditure (OpEx). This approach can mean the data center is increasingly populated by underutilized resources, which will ultimately hit the OpEx budget as the cost of managing these assets grows with every new deployment. QUESTION 27 What is the benefit of a converged network? A. easily manages a complex data center B. physically isolates SAN and UN traffic C. provides an independent security policy for each department D. consolidates the infrastructure Correct Answer: D The main driver for Unified I/O is virtualization. The number of interfaces and cables drastically increases with server virtualization due to requirements to have redundantly connected multiple segments. With Unified I/O, fewer physical adapters are required; therefore, also the amount of cables reduces. The unified fabric enables the LAN and SAN connectivity over a single physical link; therefore, the Ethernet or TCP/IP and FC traffic are multiplexed over a single copper or fiber-optic wire. With unified fabric deployment, the number of host adapters and cables is minimized, thereby simplifying the cabling and access layer. The Unified Fabric Architecture merges the LAN and SAN infrastructure into a single consolidated network and is a significant element in the Cisco Data Center Business Advantage framework.

12 If we want to deploy and redeploy IT assets across application silos to meet the changing needs of the applications teams, we need to consolidate and virtualize. QUESTION 28 What is the purpose of a data center? A. to provide maximum server availability B. to support enterprise applications C. to provide innovative technology resources D. to provide cooling for servers Finally, information systems are applications that directly or indirectly define business processes. Infrastructure refers to facilities and permanent components, such as hardware, operating systems, and local and network services. Data center virtualization must also support application silos if we are to maintain the support of the applications teams who have traditionally used a siloed architecture and infrastructure to ensure isolation and security within their application areas. QUESTION 29 Which two protocols are used with networked storage? (Choose two.) A. TCP/IP B. FiberChannel C. Token Ring D. SATA E. SCSI Correct Answer: AB The storage area network (SAN) is increasing in the data center, leveraging both Fibre Channel and IP protocols. QUESTION 30 What is the Cisco TCO Advisor tool? A. a data center performance assessment tool B. a financial analysis tool for Cisco UCS CapEx and OpEx C. a financial analysis tool for data center ROI calculations D. a tool for creating the Cisco UCS BOM list The TCO Advisor tool is designed to provide a financial analysis that compares UCS compute, network, power,

13 and cabling CapEx and OpEx costs with a conventional server solution over a three- to ten-year time period. The tool is available to registered partners. In order to access the tool, the engineer must review the Introduction to the UCS TCO Advisor Advanced Tool e-learning course. QUESTION 31 What are three of the regulatory requirements that are common across multiple regulations? (Choose three.) A. performance B. redundancy C. retention D. audit trails E. archiving F. replication Correct Answer: CDE QUESTION 32 What is the best answer to the question, "Why is a unified computing system important in today's IT industry? A. Platform costs remain flat, while management costs are increasing dramatically. B. The Internet is rapidly evolving. C. Organizational and management costs have gone down. D. More servers and switches are being deployed without significant advancement in management integration. Correct Answer: D Cisco's Unified Fabric and Unified Computing Systems provide the foundation to deliver on architectural flexibility, investment protection, and lower TCO. They offer an open, scalable, high-performance foundation on which to offer key network, computer, and application-level services. These address the new challenges that are arising in data centers and across the rest of the enterprise today by offering system-level integration and simplified design, deployment, and management. Because Cisco's Unified Fabric and Unified Computing Systems and services are design agnostic, customers can retain choice and control over how they plan their data center, without being locked in to any single architecture or technology. QUESTION 33 Who would be the first point of contact to convince that the Cisco Unified Computing System is the right platform for them? A. server administrator B. Chief Technical Officer C. storage architect D. Chief Information Officer

14 (reagarding CTO) This person usally plays a strategic technical role in the IT organization, setting the direction for major data center projects. In many organizations, this is the first and best person to convince that the Cisco Unified Computing Systems is the right platform. QUESTION 34 What is the purpose of the Netformx DesignXpert tool? A. design verification B. sizing C. BOM creation D. performance analysis Correct Answer: C NetformX DesignXpert is an application created by NetformX, which is used to create a UCS Bill of Material (BoM). The tool can also be used to verify whether the selected hardware fits the configuration. Diagrams can be created as well. This application is available to UCS ATP partners.
