SOA-C02 Monitoring, Logging, and Remediation Practice Question

This SOA-C02 practice question tests your understanding of monitoring, logging, and remediation. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

A SysOps administrator needs to monitor application logs in Amazon CloudWatch Logs for the occurrence of the string 'ERROR'. The administrator wants to create a custom metric that counts the number of 'ERROR' occurrences per 5-minute window and trigger an Amazon CloudWatch alarm when the count exceeds 10. Which action should the administrator take to create the custom metric?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Create a metric filter on the CloudWatch Logs log group that matches the term 'ERROR'.

Option B is correct because metric filters in CloudWatch Logs allow you to define a pattern (e.g., 'ERROR') that is evaluated against incoming log events. The filter counts occurrences and publishes a custom metric to CloudWatch, which can then be used to set an alarm with a period of 5 minutes and a threshold of 10.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Create a CloudWatch Events rule that triggers on 'ERROR' and publishes a metric.

    Why it's wrong here

    Amazon CloudWatch Events (now part of Amazon EventBridge) detects patterns in AWS service events, not in application log content. It cannot parse log strings to create metrics.

  • Create a metric filter on the CloudWatch Logs log group that matches the term 'ERROR'.

    Why this is correct

    A metric filter is the correct way to define a pattern to look for in log events. CloudWatch Logs uses the filter to publish a numeric metric to CloudWatch, which can then be used for alarms.

    Related concept

    Read the scenario before looking for a memorised answer.

  • Create a CloudWatch dashboard that displays the log group and set an alarm on the dashboard.

    Why it's wrong here

    A CloudWatch dashboard only visualizes existing metrics or logs. It does not create new metrics from log data, and alarms cannot be set directly on dashboard widgets.

  • Enable AWS CloudTrail on the log group and select the 'ERROR' pattern.

    Why it's wrong here

    AWS CloudTrail records API calls made within an AWS account, not application log entries. It cannot be used to extract metrics from CloudWatch Logs.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates confuse CloudWatch Logs metric filters with CloudWatch Events or CloudTrail, thinking those services can parse log content, when in fact only metric filters can extract and count patterns from log data.

Detailed technical explanation

How to think about this question

Metric filters work by scanning log events in real time as they are ingested into CloudWatch Logs. The filter pattern uses a simplified syntax (e.g., 'ERROR') or can include JSON-based extraction. The count is emitted as a metric with a default unit of 'Count', and you can specify a custom metric namespace and name. The alarm period must match the metric's aggregation window (e.g., 5 minutes) to avoid misalignment.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.

TExam Day Tips

  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
