A network engineer initially uses the ping command to help

troubleshoot a connection problem. Which troubleshooting approach

best describes this scenario?

bottom-up approach

divide-and-conquer approach

follow-the-path approach

move-the-problem approach

spot-the-difference approach

top-down approach

In which phase of the structured troubleshooting process should a

network administrator clearly communicate to the affected network

users what is going to be done and why it is being done?

the analysis of information

the definition of the problem

the elimination of possibilities

the gathering of facts

the proposal and testing of a hypothesis

In which structured troubleshooting process phase would a network

engineer ask questions such as "When did it last work?" or "Has it

ever worked?"

analyze information phase

define the problem phase

eliminate possibilities phase

gather facts phase

propose a hypothesis phase

solve the problem phase

After a network change that occurred during a scheduled maintenance

window, users were complaining about not being able to access a

local file server. Upon investigation, the administrator determined that

the problem was with the recently entered routing configurations.

Because of company policy, the administrator is not allowed to correct

the routing configuration outside of a scheduled maintenance window.

Instead, the administrator moved the file server to an accessible

subnet. Which statement describes what the administrator did?

The administrator determined a solution to the problem.

The administrator determined a workaround for the problem.

The administrator applied the "move the problem" troubleshooting approach.

The administrator applied the "spot the difference" troubleshooting approach.

Which two procedures can be implemented to ensure that current

backups of all device configurations are maintained? (Choose two.)

Log all configuration change events to a syslog server.

Password protect all devices to prevent configuration changes.

Implement a system to create automatic configuration backups.

Update configuration backups only after major network outages.

Create configuration backups as soon as an issue is reported with network performance.

What type of information can be gathered by using SNMP during the

process of collecting baseline information?

basic performance statistics via the use of show commands

basic performance statistics for Layer 2 and Layer 3 protocols

basic performance statistics about the interface load for critical network links

basic performance statistics to profile different types of traffic on the network

Which three IOS features can be used to keep the network

documentation accurate? (Choose three.)

rollback feature

policy compliance

configuration archive

performance monitoring

basic performance statistics

Embedded Event Manager

What are two facts regarding the information that is collected for

baseline creation? (Choose two.)

The information is the same for all networks.

It can be used for capacity planning.

It should be limited to only a few key performance statistics.

It can be collected using tools such as NBAR, NetFlow, and SNMP.

It should be collected only once and then archived for future reference.

What is a situation where escalation of an issue is inadvisable?

Management has not been consulted.

Escalation will slow the procedure.

The problem is actually a set of problems.

The problem has an impact on the performance of the entire network.

Solving the problem would showcase the skills and knowledge of the troubleshooter.

What is an important element of troubleshooting, regardless of the

method used?

using a single troubleshooting process

executing the steps in the same order every time

following a structured and systematic process

spending a significant amount of time analyzing the information

To correct an issue that was discovered a few days earlier, an

administrator makes a change during a regularly scheduled

maintenance window. After making the change, the administrator

discovers that a new problem has occurred. What should the

administrator do next?

Rollback the change and resume the troubleshooting process.

Continue making changes until the symptoms disappear.

Leave the change in place and troubleshoot the new problems at a later time.

Gather information about the new problem and form a new hypothesis.

After a proposed solution has been implemented, the network

administrator realizes that new problems have been introduced by the

changes. What is the next step in the troubleshooting process?

Propose a hypothesis.

Execute the rollback plan.

Determine an appropriate workaround.

Escalate the problem to another department.

Which three types of data are useful for creating a baseline? (Choose

three.)

number of infrastructure routers and switches

Remote Monitoring (RMON), Network Based Application Recognition (NBAR), and NetFlow statistics

DHCP and NAT translation statistics

network performance characteristics

switch interface statistics of all access ports

basic performance statistics like the interface load for critical network links and the CPU load and

memory usage of routers and switches

What are two limitations of an ad hoc troubleshooting approach?

(Choose two.)

inefficient use of time and resources

only applicable to physical layer problems

difficult to transfer the job to someone else

can only be used after a structured approach has failed

requires more technical knowledge than a structured approach

What is a benefit of change control during the processes of regular

network maintenance?

simplification of the process for creating a network baseline

reduction in the frequency and duration of unplanned outages

elimination of the need to troubleshoot planned outages

elimination of the need to perform a regular network backup

Which two components are normally considered part of change

control? (Choose two.)

the cost of network changes

the time when changes can be made

the technology that is used to implement changes

the authorization that is required to make changes

the staff changes that are required to carry out repairs

A network administrator executes the show processes cpu command

on a production router and notices that the average CPU load over the

past 5 seconds was 97% and over the last one minute was around

39%. What should the administrator do next?

Nothing. This is normal behavior for an ISR router.

Contact the service provider because the contract is not being fulfilled as specified in the SLA.

Compare the result to the baseline for an accurate assessment.

Replace the router as soon as possible because it has reached capacity

What is a symptom of an incorrectly applied network command when

issued under the routing process?

a down status on an interface

a timeout message when attempting to ping a device on another network

a routing protocol that is not running

a user who is unable to connect to machines that are located on the same subnet

The help desk receives several calls on Monday morning stating that

users cannot connect to a local print server that was working on

Friday. Which statement about the problem would be correct?

The inability to connect to the print server is a symptom of a problem.

The inability to connect to the print server is the problem.

The connectivity problem occurred Monday morning.

The inability to connect to the print server caused the problem.

A user creates a trouble ticket indicating that the Internet is

inaccessible. The network administrator receives the ticket and

determines that this user is the only one having problems.

A ping command issued from the administrative PC to the user PC is

successful. What should the administrator do next?

Escalate the issue to the desktop support group.

Contact the ISP to determine if there is an issue on the ISP side.

View the route table on the core router to determine if there is a routing issue.

Swap out the patch cable between the user PC and the switch to determine if that solves the

problem.
