NO.5 Characterizing an existing network requires gathering as much information about the network
as possible. Which of these choices describes the preferred order for the information-gathering
process?
A. site and network audits, traffic analysis, existing documentation and organizational input
B. existing documentation and organizational input, site and network audits, traffic analysis
C. traffic analysis, existing documentation and organizational input, site and network audits
D. site and network audits, existing documentation and organizational input, traffic analysis
Answer: B
Explanation:
This section describes the steps necessary to characterize the existing network infrastructure and all
sites. This process requires three steps:
Step 1. Gather existing documentation about the network, and query the organization to discover
additional information. Organization input, a network audit, and traffic analysis provide the key
information you need. (Note that existing documentation may be inaccurate.) Step 2. Perform a
network audit that adds detail to the description of the network. If possible, use traffic-analysis
information to augment organizational input when you are describing the applications and protocols
used in the network. Step 3. Based on your network characterization, write a summary report that
describes the health of the network. With this information, you can propose hardware and software
upgrades to support the network requirements and the organizational requirements.
NO.6 Where in the Cisco Enterprise Architecture model does network management reside?
A. Enterprise data center module
B. Enterprise campus module
C. Enterprise edge module
D. Service Provider edge module
E. Service Provider data center module
