Chapter 7 : Lab 7.3.6 Identifying Risks and Weaknesses in the DesignTelah dituliskan: Januari 8, 2011
Task 1: Identify areas of risk and weakness in the server farm implementation
Step 1: Analyze the physical topology
Examine the server farm topology as one entity and as a part of the entire FilmCompany topology. Look for each of the risks and weaknesses listed in the chart. Describe the devices, connections, and issues that you find, or record None found if the design appears to avoid risks in that area.
|Weakness||Risk||Description of Location and Devices|
|Single point of failure||If a device fails, a portion of the network will be inoperable.|
|Large failure domain||If a device or link fails, a large portion of the network will be affected|
|Possible bottlenecks||If the traffic volume increases, thereis a potential for response time todegrade.|
|Limited scalability||If the network grows more rapidly than expected, a costly upgrade will be needed.|
|Overly-complex design||If the design is too complex, the current staff will not be able to support it properly.|
|Other possibleweaknesses (specify):|
Step 2: Analyze the results and conclusions of the testing
Basic router and switch configurations were modified to support the following protocols and functions.
Evaluate the results and conclusions that were drawn from the testing. Identify any areas where modifications to the configuration would provide better results, both now and in the future.
|No Change Needed||Modifications Possible|
|VLAN port assignments|
|VTP client/server assignments|
|Root bridge designations|
|Traffic filtering through ACLs|
Task 2: Suggest modifications to the design to address identified risks and weaknesses
From the analysis performed in Task 1, list each risk or weakness and suggest possible changes to the
design to minimize or eliminate it.
