3M0-211 Certified Enterprise LAN Specialist Certification Boot Camp

Demo Question 19.

Answer: B Case Study 2, MalutiUniversity(MU) Scenario The university is a vibrant academic community of some 21 ,000 students and 4,500 staff members. A major project is underway to: upgrade the Maluti campus network to deliver a secure, managed, fully switched infrastructure. To provide an acceptable level of service to the 5,700 users, a multiple-Gigabit or 10-Gigabit backbone infrastructure is needed. All shared media devices will be replaced with switches Finally, a new LAN telephony system will replace the aging PABX system, which has its own infrastructure and 4,500 extensions The main data center in Building 9 houses 28 servers and is the campus LAN center. Buildings 9, 16, 20, 35 and 38 form the network core, with each building supporting up to 10 smaller campus buildings. The majority of the buildings have four floors, with the user population spread fairly evenly across the floors. Each floor has its own central wiring closet, and all wiring to the desktops is currently based on Cat5/Cat5E UTP. Redundancy in the network is very important - the backbone must be designed with alternate paths and routes. Other key requirements include a secure network environment, provide growth for users and servers, and centrally monitored and managed. Recently, 400 network points were installed in one of the student residences. The design included 3Com SuperStack 3 Switch 4400 switches for network-user connectivity linked to Switch 4060 switches configured as an XRN unit in the building basement. The residence has a direct connection to the data center in Building 9. There will be a requirement to extend the network to all residences, adding 3,500 network points to the campus network. A special gigabit-Ethernet requirement exists for Buildings 45 and 46: Building 45 has 17 high-performance workstations and four local servers, and Building 46 has 14 high-performance workstations and six local servers. All need gigabit-Ethernet LAN connections. The network must support the following requirements: 1. The data center in Building 9 connects to each of the four distribution buildings (Buildings 16,20, 35 and 38) via four single-mode fiber cables, forming the network core. Each building supports between four and 10 additional satellite buildings via redundant muitimode50/125fiber. 2. The backbone must be highly redundant, multi-Gigabit Ethernet/10 Gigabit, non-blocking, wire-speed and support Link Aggregation and TCP/IP Layer 3 routing. Note other protocols will be handled with Layer 2 switching within VLANs 3. The data center server farm must have 10/100/1000BASE. T links, high availability with dual-homing desirable 4. Multi-story buildings have multimode 50/125 fiber link between floors 5. End users require Layer 2 switching, 10/100BASE. T autosensing, auto MDIX links 6. Traffic prioritization(IEEE802.1p and/Diffserv);VALNs and VLAN tagging (IEEE80210); and Qos prioritization of application of applications and IP telephony is required 7. The highest level of security using IEEE802.1X network Login is needed 8. The new network initially will have 5,700 user ports. An additional 3,500 residence ports and 4,500 LAN telephony phone swill be added overtime 1. All new equipment must support IEEE 802,3 Ethernet standards.
