CCNA 4 - Module 8
1. Which two pieces of information are typically found on a logical network diagram? (Choose two.)
- cable types
- connector types
- interface identifiers
- DLCI for virtual circuits
- operating system versions

2. Excessive broadcasts are generally a symptom of a problem at which layer?
- physical
- data link
- network
- transport

3. What is one example of aphysical layer problem?
- incorrect encapsulation
- incorrect STP configuration
- incorrect ARP mapping
- incorrect clock rate

4. Which two components should be taken into consideration when establishing a network baseline? (Choose two.)
- information about the network design
- IP addressing allocation on the network
- requirements about the service provider setup
- requirements for accesscontrol lists to regulate traffic
- expected performance under normal operating conditions

5. Refer to the exhibit. Which two steps should be taken during the process of creating network documentation? (Choose two.)


- Record the information about the devices discovered in the Campus network only.
- Record the information about the devices discovered in the entire network, including theremote locations.
- Transfer any information about the devices from the network configuration table that corresponds to a component of the topology diagram.
- Transfer only the Layer 2 and Layer 3 information about the devices from the network configuration table that corresponds to a component of the topology diagram.
- Transfer the recorded information about the devices from the networkconfiguration table gathered during peak network utilization that corresponds to a component of the topology diagram.

6. Which two statements are true concerning logical networking models? (Choose two.)
- TCP/IP splits the lowest layer of the OSI model into two separate layers.
- The top layer of the TCP/IP model combines the functions of the top three OSI layers.
- Troubleshooting with theTCP/IP model requires different techniques than with the OSI model.
- The network access layer is responsible for exchanging packets between devices on a TCP/IP network.
- The Internet layer provides communication between applications, such as FTP, HTTP, and SMTP on separate hosts.
- The TCP/IP network access layer corresponds to the OSI physical and data link layers.

7. Clients across thecompany are reporting poor performance across all corporate applications running in the data center. Internet access and applications running across the corporate WAN are performing normally. The network administrator observes a continual broadcast of random meaningless traffic (jabber) on the application server LAN in the data center on a protocol analyzer. How should the administrator starttroubleshooting?
- The jabber in the data center indicates a local physical layer problem. Use the protocol analyzer to determine the source of the jabber, and then check for a recent NIC driver update or bad cabling.
- Because all clients are experiencing application problems, the administrator should use a top-down approach with the application servers in the data center.
- The scope of the problemindicates a likely routing or spanning-tree problem. Begin by checking routing tables, and follow up using appropriate STP show commands to find a loop if routing is working normally.
- Poll the staff to determine if any recent changes have been made. Back out all the changes one by one until the error condition is fixed.

8. Which troubleshooting approach is suggested for dealing with a complexproblem that is suspected of being caused by faulty network cabling?
- bottom up
- top down
- divide and conquer
- middle out

9. A technician has been asked to make several changes to the configuration and topology of a network and then determine the outcome of the changes. What tool can be used to determine the overall effect caused by the changes?
- baselining tool
- knowledge base
-...
