14.AMFAB Environmental Consulting (AMFAB), an environmental consulting company, based near Atlanta, Georgia, uses a PBX for its campus phone system. The PBX cannot support all the new features that AMFAB requires, so the company has decided to change its system from traditional TDM to IP telephony. The campus currently has approximately 922 users in three fourstory office buildings, a single story R&D facility, and a scale building. It will be your job to determine what information is needed for the proper design of the company's converged network.
During preliminary investigation, here is what there is to be found: 922 employees, of which 868 have phones that are DID. The rest are lobby and break room phones, departmental phones, etc. for a total of 895 phones. Each employee with DID has a personal mailbox, as does every department with a group phone, for a total of 881 voice mail boxes. There are 12 people in marketing, each of whom uses the phone considerably more than the average user does. Most of these calls are external calls. There are 7 people in technical support, each of whom uses the phone considerably more than the average user does. Most of these calls are internal calls. The current dial plan uses fourdigit dialing for extensiontoextension calls,and dialing 9 for outside calls(local and long distance). AMFAB doesn't have a current traffic analysis of their network. They believe they have enough bandwidth for anything they might want to run, including IP telephony, but have no concrete documentation to back that up. Each of buildings A, B, and C has a combination MDF/IDF on the ground floor, with an IDF on each upper floor. The IDFs are connected to the MDFs via multiple
25pair cable bundles for phones and two pairs each multimode fiber optic cable for data. Each of the 895 phones is cabled using Category 3 UTP cable out from the IDFs. Each station in the R&D building has two Category 5 UTP cable drops, plus phone. All buildings on the campus are dataconnected via an FDDI ring with the exception of the scale building, which is connected to the R&D building via Category 5 UTP cable. The AMFAB facility spans two counties, so the R&D building and the scale building are serviced by a different PSAP than are buildings A through C. Building C houses the main computer room that contains all the company servers. The main computer room in Building C also contains the PBX with PSTN connectivity, and the Internet connection(s). There is a pair of Cisco 2514 routers providing connectivity to the Internet; they are set up with HSRP. The data network was built using token ring LANs connected via the FDDI ring. AMFAB is interested in migrating its phone system to IP telephony, vs. a massive weekend cutover.
On the basis of information discovered during the investigation phase of the design, it has been decided that the singlesite call processing model is the proper deployment model for AMFAB. The access layer devices will be placed in the IDFs, the distribution layer devices will be placed in the MDFs, and the core will be deployed in the computer room. Each IDF services approximately 70 to 75 users. AMFAB is using Token Ring with an FDDI backbone. The network is to be migrated to an Ethernet network. AMFAB has had many network outages in their current network, and is concerned with network availability, especially as the phone system will now be residing on the same network.
A.L2 access layer with perVLAN spanning tree (PVST) with an L2 distribution layer, with common spanning tree (CST) running with an L3 core, with OSPF in the core
B.L3 at the access and distributions layers running OSPF across a loopfree L2 core with no spanning tree.
C.L3 at the access distribution, and core layers, with OSPF as the routing protocol running on all devices
D.L3 at the access layer running OSPF with the L3 core over the L2 distribution layer
E.L2 at the access layer with perVLAN spanning tree (PVST) with an L3 distribution layer, with runs OSPF with an L3 core
Answer: E
15.During migration from Token Ring to Ethernet, routers will be deployed to allow access between the existing Token Ring and the new Ethernet networks. Where in the network should these routers be deployed?
A.at the core of the network so that each IDF can continue to use the FDDI backbone.
B.in the individual IDFs so that individual users can be migrated from the Token Ring to the Ethernet network to minimize each individuals down time.
C.at each MDF so that each IDF can be migrated separately and possible widespread network outages
D.in the computer room so that the Token Ring and Ethernet networks are only connected at one location to minimize risk
Answer: C
16.Each IDF currently supports a single ring per floor no matter how many different departments are on that floor. Which VLAN deployment scheme would provide each department with load balancing, high availability, and security on a perfloor basis?
A.Each department would have a separate data and voice VLAN. Both departmental VLANs would be trunked over a single path from the IDF to the MDF.
B.Since most departments are small, each department would use a single VLAN for data and voice. Each departmental VLAN would be trunked from the IDF to the MDF over two paths, a primary and a backup.
C.Each department would use two VLANs, one for data and one for voice. These VLANs would be trunked over redundant uplinks from the IDF to the MDF.
D.Each floor would use two VlANs no matter how many departments are located there. The two VLANs would have a primary and backup path on each up link from the IDF to the MDF.
Answer: C
17.Each IDF will function at Layer 2. Which deployment solution will provide the highest availability and still provide for inline power to the IP phones? (Choose two.)
A.Using the current data cable drop, deploy a dual VLAN solution where FLP would make the determination of providing inline power.
B.Deploy a single chassisbased switch with dual Layer 3 supervisors and a single connection to the MDF.
C.Use the present dualcable drop to each desktop, providing inline power on both drops and use FLP to make the determination of providing inline power.
D.Deploy a stackable switch solution with dual connections from each switch to the MDF.
E.Use the present dualcable drop to each desktop, providing inline power on the cable the current data device is connected to.
F.Deploy a chassis solution with dual connections to the MDF.
Answer: A, F
18.How can high availability be accomplished with a Fast Ethernet or Gigabit Ethernet network?
A.Deploy dualconnected core switches, each with a single connection to each MDF.
B.Deploy dual MDF switches, each with dual connections to the IDF switches.
C.Deploy stacked IDF switches that are dual connected to each core switch in the computer room.
D.Deploy dual MDF switches that each connect to two core switches in the computer room.
