Quick Answer
The answer is Time Series and Number. These are the two valid CloudWatch dashboard widget types from the options, as confirmed by the AWS documentation for dashboard customization. A Time Series widget graphs one or more metrics over time, making it essential for tracking trends like CPU utilization or request latency, while a Number widget displays a single current value—such as a sum or average—often with a trend arrow to show direction. On the AWS Certified SysOps Administrator Associate SOA-C02 exam, this question tests your ability to distinguish between the six widget types (including Text, Alarm, Logs, and Explorer) and to avoid traps like confusing a metric’s statistic with a widget type. A common memory tip is to remember that only Number and Time Series are purely metric-focused widgets; the others serve different purposes like logs or alarms. For quick recall, think “N and T” for Number and Time Series—the two core widgets for raw metric display.
This SOA-C02 practice question tests your understanding of monitoring, logging, and remediation. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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 is configuring a CloudWatch dashboard to monitor an application. Which TWO of the following are valid widget types that can be added to a CloudWatch dashboard?
Line
Why wrong: 'Line' is not a widget type; time series can show lines.
Alarm
Why wrong: Alarm is not a widget; alarm status can be shown via a separate widget.
Bar chart
Why wrong: Bar chart is not a standard CloudWatch dashboard widget.
Number
Number widget displays a single metric value.
Time Series
Time series widget displays metric data over time.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Number
Option D (Number) is correct because CloudWatch dashboards support the Number widget type, which displays a single metric value as a numeric statistic (e.g., sum, average, or sample count) and can optionally show a trend arrow. This widget is ideal for showing key performance indicators like current error count or latency.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Line
Why it's wrong here
'Line' is not a widget type; time series can show lines.
Alarm
Why it's wrong here
Alarm is not a widget; alarm status can be shown via a separate widget.
Bar chart
Why it's wrong here
Bar chart is not a standard CloudWatch dashboard widget.
Number
Why this is correct
Number widget displays a single metric value.

Common exam traps
The trap here is that candidates confuse the visual sub-types (like 'Line' or 'Bar chart') with the actual widget types, leading them to select those as valid options when only 'Time Series' and 'Number' are the correct top-level widget types in the CloudWatch dashboard widget JSON schema.
Trap categories for this question
Command / output trap
'Line' is not a widget type; time series can show lines.
Detailed technical explanation
CloudWatch dashboard widgets are defined using a JSON structure that specifies the 'type' field. The valid top-level widget types are 'metric' (which renders as a time series graph with sub-types like line, bar, stacked area, or pie), 'number', 'text', 'log', and 'alarm'. The 'Time Series' widget type (Option E) is the correct name for the metric graph widget, and it supports multiple visual styles via the 'stat' and 'period' parameters. Under the hood, the 'Number' widget uses the GetMetricStatistics API to fetch a single aggregated value, while the 'Time Series' widget uses GetMetricData to retrieve time-ordered data points.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
