D: Gather information, question users, identify symptoms, note changes, and reproduce if possible before making fixes. However, it does not most directly satisfy the requirement in this scenario: preserve a troubleshooting record for future support and organizational learning.

E: Choose a remediation approach and consider potential effects or rollback needs. However, it does not most directly satisfy the requirement in this scenario: preserve a troubleshooting record for future support and organizational learning.

Learning point: Use Document findings and lessons learned when the key requirement is to preserve a troubleshooting record for future support and organizational learning.

Question 22

A network technician at Woodgrove Bank is troubleshooting a new floor deployment. The team has isolated the key need as follows: begin troubleshooting by collecting evidence and clearly defining the symptoms. Which concept should be applied or investigated first?

Test the theory
Document findings and lessons learned
Identify the problem
Establish a theory of probable cause
Verify full functionality and preventive measures

Correct answer: C

Option review:

B: Record symptoms, root cause, actions, outcome, and useful lessons. However, it does not most directly satisfy the requirement in this scenario: begin troubleshooting by collecting evidence and clearly defining the symptoms.

C: Gather information, question users, identify symptoms, note changes, and reproduce if possible before making fixes. This directly satisfies the requirement: begin troubleshooting by collecting evidence and clearly defining the symptoms.

E: Confirm the service works end to end and apply reasonable steps to reduce recurrence. However, it does not most directly satisfy the requirement in this scenario: begin troubleshooting by collecting evidence and clearly defining the symptoms.

Learning point: Use Identify the problem when the key requirement is to begin troubleshooting by collecting evidence and clearly defining the symptoms.

Question 23

A field technician at Blue Yonder Airlines is troubleshooting a service-recovery review. The team has isolated the key need as follows: move from observed symptoms to a plausible cause without immediately changing production. Which concept should be applied or investigated first?

Implement the solution or escalate
Document findings and lessons learned
Identify the problem
Test the theory
Establish a theory of probable cause

Correct answer: E

Option review:

A: Carry out the planned fix when authorized/within scope or escalate when necessary. However, it does not most directly satisfy the requirement in this scenario: move from observed symptoms to a plausible cause without immediately changing production.

B: Record symptoms, root cause, actions, outcome, and useful lessons. However, it does not most directly satisfy the requirement in this scenario: move from observed symptoms to a plausible cause without immediately changing production.

C: Gather information, question users, identify symptoms, note changes, and reproduce if possible before making fixes. However, it does not most directly satisfy the requirement in this scenario: move from observed symptoms to a plausible cause without immediately changing production.

D: Validate whether the suspected cause actually explains the problem; if not, form a new theory or escalate. However, it does not most directly satisfy the requirement in this scenario: move from observed symptoms to a plausible cause without immediately changing production.

E: Use evidence and structured approaches such as top-down, bottom-up, or divide-and-conquer to form likely causes. This directly satisfies the requirement: move from observed symptoms to a plausible cause without immediately changing production.

Learning point: Use Establish a theory of probable cause when the key requirement is to move from observed symptoms to a plausible cause without immediately changing production.

Question 24

A network support specialist at Contoso Health is troubleshooting a branch-office rollout. The team has isolated the key need as follows: confirm or reject the suspected cause before committing to a fix. Which concept should be applied or investigated first?

Verify full functionality and preventive measures
Establish a plan of action
Implement the solution or escalate
Test the theory
Identify the problem

Correct answer: D

Option review:

A: Confirm the service works end to end and apply reasonable steps to reduce recurrence. However, it does not most directly satisfy the requirement in this scenario: confirm or reject the suspected cause before committing to a fix.

B: Choose a remediation approach and consider potential effects or rollback needs. However, it does not most directly satisfy the requirement in this scenario: confirm or reject the suspected cause before committing to a fix.

C: Carry out the planned fix when authorized/within scope or escalate when necessary. However, it does not most directly satisfy the requirement in this scenario: confirm or reject the suspected cause before committing to a fix.

D: Validate whether the suspected cause actually explains the problem; if not, form a new theory or escalate. This directly satisfies the requirement: confirm or reject the suspected cause before committing to a fix.

Learning point: Use Test the theory when the key requirement is to confirm or reject the suspected cause before committing to a fix.

Question 25

A systems administrator at Litware Manufacturing is troubleshooting a campus refresh. The team has isolated the key need as follows: decide exactly how to fix the confirmed cause while considering impact. Which concept should be applied or investigated first?

Identify the problem
Test the theory
Document findings and lessons learned
Implement the solution or escalate
Establish a plan of action

Correct answer: E

Option review:

A: Gather information, question users, identify symptoms, note changes, and reproduce if possible before making fixes. However, it does not most directly satisfy the requirement in this scenario: decide exactly how to fix the confirmed cause while considering impact.

B: Validate whether the suspected cause actually explains the problem; if not, form a new theory or escalate. However, it does not most directly satisfy the requirement in this scenario: decide exactly how to fix the confirmed cause while considering impact.

C: Record symptoms, root cause, actions, outcome, and useful lessons. However, it does not most directly satisfy the requirement in this scenario: decide exactly how to fix the confirmed cause while considering impact.

E: Choose a remediation approach and consider potential effects or rollback needs. This directly satisfies the requirement: decide exactly how to fix the confirmed cause while considering impact.

Learning point: Use Establish a plan of action when the key requirement is to decide exactly how to fix the confirmed cause while considering impact.
