2 Exactquestions 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 /Reference: 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. /Reference: 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.

The Cisco UCS VIC M81KR Virtual Interface Card is a type of adapter, or mezzanine card, available in a Cisco

8 UCS blade server that directly supports virtualization. It supports NIC virtualization for either a single operating system or for VMware ESX. QUESTION 16 Which components are building blocks of a data center? (Choose two.) A. processes B. building systems C. information systems D. financial resources E. infrastructure Correct Answer: CE /Reference: Before defining what a data center is, let's take a look at the different domains that make up information technology. The business strategy domain refers to the match an organization makes between its internal resources and skills and opportunities and risks created by the external environment. Below that, functional or organizational groups define workgroups, processes, standards, and policies. A project is considered an undertaking with a defined starting point and defined objectives by which completion is identified. A process is a specific order of work activities or the task of transforming input into output. 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. QUESTION 17 Which feature is the most important Cisco differentiator compared to other vendors that offer server virtualization technology? A. a 10GE architecture B. extended memory architecture C. an advanced RAID architecture D. extended fabric architecture /Reference: The Cisco Extended Memory Architecture employs a custom memory controller chipset that virtualizes DIMMs as seen by the CPU memory controller.

A. client-server B. decentralized C. centralized D. recentralized Correct Answer: D

9 /Reference: QUESTION 19 Which of these is a benefit of deploying the Cisco Unified Computing System solution? A. It has separate chassis for different server types. B. It has separate Cisco UCS clusters for different server types. C. Different server types can be intermixed in a single chassis. D. A single chassis must be deployed with two fabric interconnects Correct Answer: C /Reference: Next are the blades themselves. There are two blade types, and these types can be mixed within the enclosure. QUESTION 20 The Intelligent Network can play a vital role in which three networking environments? (Choose three) A. storage networking B. application networking C. data networking D. wide-area networking E. security networking F. media networking Correct Answer: ABC /Reference: Cisco has identified three networking environments in which the intelligent network can play a vital role. These are data networking, storage networking, and application networking. These represent three functional areas which in some cases overlap. QUESTION 21 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. /Reference: 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

10 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. QUESTION 22 What is the current approach to the data center computer architecture scalability? A. scale in B. scale out C. scale down D. scale up Correct Answer: A /Reference: 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 /Reference: 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.

11 /Reference: 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 Which two adapter cards are supported by Cisco UCS B-Series Rack-Mount Servers? (Choose two.) A. Fire wire B. Ethernet C. HDMI D. Wireless E. CNA F. USB G. VIC G /Reference: Cisco offers two Converged Network Adapters (CNA). These are called converged because they contains both an application-specific integrated circuit (ASIC) for Fibre Channel and an ASIC for Data Center Ethernet as well as a third ASIC onboard, called the Menlo ASIC. The Menlo ASIC combines Fibre Channel and Ethernet communication into 10 Gigabit Ethernet. Cisco uses cards manufactured by both Emulex (called the UCS CNA M71KR-E ) and QLogic (called the UCS CNA M71KR-Q). These CNAs cost more than the UCS 82598KR-CI, but you don't have to worry about using an OS with the FCoE stack; all you need are the appropriate drivers. The CNAs are called the "Compatibility" adapter in this slide because it has a Fibre Channel chip and a Data Center Ethernet chip on it, along with the Menlo chip that combines the two. The UCS CNA M71KR is a virtual interface card (VIC). It differentiates itself from UCS 82598KR-CI and the two CNAs in that it can create what appears to the OS as hardware Host Bus Adapters (HBAs) and Ethernet. It is a virtualized network adapter. Whereas the CNAs limit you to two Ethernet uplinks and two HBA uplinks, the VIC can create up to 128 virtual NICs. A customer could easily create a bladed server that looks like it has 40 separate Ethernet or Fibre Channel cards in it, and of course that configuration requires reduced wiring and far less power. The VIC is cutting-edge technology, and ergo is the most expensive of the three options. The UCS M81KR Virtual Interface Controller (VIC) for the UCS blade series has now been complemented by the UCS P81E Virtual Interface Card for use with Cisco UCS C-Series Rack-Mount Servers. 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

12 /Reference: 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 Which two statements best describe the benefits of the Cisco UCS C-Series Rack-Mount Servers? (Choose two.) A. the use of patented Cisco Extended Memory technology B. 40-GB Ethernet Unified Network Fabric C. single-vendor infrastructure D. proprietary high-latency 1-GB Ethernet Unified Fabric E. a platform purpose-built for virtualization Correct Answer: AE /Reference: While VMware can be used to replace many of the physical servers within an organization, VMware is still an application and operating system that needs a server platform to run on. With the integration and visibility into network virtualization, the Cisco UCS system is uniquely positioned as a preferred platform on which to run VMware ESX. The C-Series Rack-Mount Servers come in seven different versions including the C200 M1 and M2 High- Density Rack-Mount Servers, the C210 M1 and M2 General-Purpose Rack-Mount Servers, the C250 M1 and M2 Extended Memory Rack-Mount Servers, and the C460 M1 High-Performance Rack-Mount Server. QUESTION 28 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 /Reference: 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. 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.

13 QUESTION 29 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 /Reference: 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 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 /Reference: The TCO Advisor tool is designed to provide a financial analysis that compares UCS compute, network, power, 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 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 /Reference: 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

14 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 32 Which characteristic would you describe as a key differentiator for the Cisco C-Series Rack-Mount Servers as compared to the competition? A. serviceability B. virtualization C. scalability D. availability /Reference:
