5 E. One Switch 8810 Answer: C, E Section 3: Sec Three (75 to 80) Details: Topic 4, BantryBayCity Council Scenario Bantry Bay City Council has an existing Ethernet-based Local Area Network(LAN) Rapid growth has put the network infrastructure under pressure The Council is relocating to a new complex with a number of separate one- and two-story buildings It is installing a high-performance network infrastructure in the new complex. The Council expects a dramatic increase in the demand for network bandwidth The network core must be a high-bandwidth LAN with a Gigabit backbone linking the four main buildings to the data center. The data center forms the central core. The network core/data center service must be maintained if a switch or switch component fails. Also, the core Gigabit-port capacity must provide for 25% growth. The server farm, located at the data center, must always be accessible. The server farm will have at least 12 servers Resiliency and reliability are paramount, especially for the network core and server farm. New switches, wiring closets and building sites must be easily added to the network when required. Virtual LAN (VLAN) support is required to contain broadcast traffic. Network telephony and video are likely to be implemented, so it is essential that all equipment support Ouality of Service (QoS). The desktop connections must be switched, auto-negotiating 10!100- Mbps unshielded twisted pair (UTP) links. The network must support the following requirements: 1. Ethernet standards-based network 2. Data center only connects to the four main buildings 3. Each of the four main buildings requires a distribution layer to connect the surrounding smaller buildings and the wiring closets to the data center 4. 4-Gbps links between the data center and the distribution layer 5.Mix of fiber and UTP 1-Gbps links between the wiring closets and the distribution layer Full service must be maintained if a core or server-farm switch fails 6. The network backbone must use TCP/IP Layer 3 routing 7. Access Control Lists (ACLs) that can filter at Layer 2/Layer 3/Layer 4 are required at the core of the network 8. All equipment must support Layer 2-4 QoS classification and marking, with bandwidth guarantees and bandwidth limiting in the core. The data center and the four main buildings: 1. City Power, Library, Mayor's Office and Conference Center-each requires 96 ports evenly divided between two floors. 2. Each main building is connected to the data center and to four smaller, single-floor buildings on the campus 3. The distance between these buildings is 250 to 500 meters, with existing multimode 50-micron fiber - except for three small buildings, the Store (720 meters), Maintenance 30

6 Department (630 meters) and Waste Dept (1600 meters), which are connected via fiber connections over a single-mode 9-micronfiber 1. All the smaller, single-floor buildings require 48 network ports - except the City Engineer, Call Center, and Tourism and Publicity buildings, which each need 96 ports. 2. The entire network will have approximately 1,000 ports Topic 4, BantryBayCity Council (6 Questions) QUESTION: 75 Which solution would you recommend as the distribution-layer switch for each of the Bantry Bay four main buildings that connect to the data center and to the smaller buildings on campus? A. Two Switch 4050 B. Two Switch 4060 C. Two SuperStack 3 Switch 4924 D. Two SuperStake 3 Switch 4950 Answer: B QUESTION: 76 If you choose two Switch 4060s for each of the Bantry Bay distribution layer buildings, which three would you recommend to the customer to provide maximum resiliency and throughput? (Choose three) A. Redundant internal power supplies B. Resilient Links to maximize backbone redundancy C. SuperStack 3 Advanced Redundant Power System D. XRN Interconnect Kit to connect the two distribution-layer switches E. IEEE802.3 ad Link Aggregation to maximize backbone bandwidth and reliability F. SuperStack 3 Switch BASE-T module to connect the two distribution-layer switches Answer: A, D, E QUESTION: 77 If you choose the SuperStack 3 Switch 4924 to support the Bantry Bay server farm, which three customer benefits are attained from using an XRN interconnection Kit with the two SuperStack 3 Switch 4924 server-farm switches? (Choose three) 31

7 A. The Fabric Interconnect has an 8-Gbps (16-Gbps full duplex)switching limit B. The two switches would share one IP address and be managed as a single entity C. Any number of ports can join a Link Aggregation trunk with all ports active and transporting data D. XRN Distributed Resilient Routing (DDR) uses a "Master Router" to perform all the routing across the Fabric. E. XRN Distributed Resilient Routing (DDR) allows switches in the Fabric to act as a single logical router, which provides router resiliency in the event of a unit failure in the Fabric F. XRN Distributed Link Aggregation (DLA) guarantees high levels of resiliency, because a failure in one of the member links results in automatic redistribution of traffic across the remaining links Answer: B, E, F QUESTION: 78 If you reocommend a single Switch 7700R 8-Slot Chassis to create the hihly-resilient backbone, which three switch components would Bantry Bay require for the data center's backbone-core switch? (Choose three) A. One Switch 7700R Starter Kit (3C16852) B. One Switch 7700 AC Power Supply (3C 16854) C. Three Switch 7700 AC Power Supplies (3C 16854) D. One Switch 7700R 8-Slot Fan Assembly (3C 16855) E. One Switch 7700R Gigabit Ethernet Redundant Switching Fabric (3C 16857R) Answer: A, B, E QUESTION: 79 Which two 3Com solutions would you recommend for the Bantry Bay data center, backbone core? (Choose two) A. Two Router 6040 B. One Router 6080 C. Two Switch Slot Chassis D. Two switch s;ot chassis E. One switch 7700R 8-slot Chassis 32

8 Answer: D, E QUESTION: 80 If you recommend a Switch 7700 for the data center backbone-core solution, which three modules/interfaces would the customer require for each of the two data center backbonecore switches? (Choose three) A. Eight 1000BASE-SX GBICs (3CGBIC91) B. Eight 1000BASE-LH70 GBICs (3CGBIC97) C. One Switch port 1000BASE-T module (3C16859) D. One Switch port 1000BASE-X module (3C16858) E. Two Switch port 1000BASE-T module (3C16859) F. Two Switch port 1000BASE-X module (3C16858) Answer: A, C, D 33
