💡 Hint

Common Mistakes

Using 'json' instead of a language code.

Using 'all' which is not a valid language parameter.

The AWS CLI command requires the language code, such as 'en' for English, to list Trusted Advisor checks.

💡 Hint

Common Mistakes

Using 'en' as check ID.

Using 'all-checks' which is not a valid check ID.

The check ID is a unique identifier string for each Trusted Advisor check, usually a UUID format.

💡 Hint

Common Mistakes

Using 'refresh' as a check ID.

Using 'en' which is a language code, not a check ID.

The refresh command requires the check ID or 'all' to refresh all checks.

Fill both blanks to create a JSON filter for Trusted Advisor checks with status 'error'.

AWS

{"checks": [[1]], "status": "[2]"}

Drag options to blanks, or click blank then click option'

A"checkId": "12345678-1234-1234-1234-123456789012"

D"checkId": "87654321-4321-4321-4321-210987654321"

💡 Hint

Common Mistakes

Using 'warning' instead of 'error' for status.

Using invalid checkId format.

The JSON filter needs a valid check ID string and the status 'error' to filter checks with errors.

5fill in blank

hard

Fill all three blanks to create a Python dictionary for filtering Trusted Advisor checks by category and status.

AWS

filter_criteria = {"category": "[1]", "status": "[2]", "checkId": "[3]"}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'security' category when filtering cost checks.

Using 'warning' instead of 'error' status.

The category is 'cost_optimizing', status is 'error', and checkId is a valid UUID string.

Practice

1. What is the primary purpose of AWS Trusted Advisor?

easy

A. To monitor real-time application logs

B. To deploy new AWS services automatically

C. To provide recommendations for cost savings, security, and performance improvements

D. To create backups of AWS resources

Solution

1. Step 1: Understand Trusted Advisor's role

   AWS Trusted Advisor analyzes your AWS environment and suggests improvements in cost, security, fault tolerance, and performance.

2. Step 2: Compare options with Trusted Advisor's functions

   Only To provide recommendations for cost savings, security, and performance improvements matches Trusted Advisor's purpose; others describe different AWS services.

3. Final Answer:

   To provide recommendations for cost savings, security, and performance improvements -> Option C

4. Quick Check:

   Trusted Advisor = Recommendations [OK]

Hint: Trusted Advisor gives advice, not deploys or monitors [OK]

Common Mistakes:

• Confusing Trusted Advisor with AWS CloudWatch
• Thinking it deploys services automatically
• Assuming it manages backups

2. Which AWS Trusted Advisor category checks for unused or idle resources to help reduce costs?

easy

A. Cost Optimization

B. Fault Tolerance

C. Security

D. Performance

Solution

1. Step 1: Identify the category related to cost savings

   The Cost Optimization category focuses on reducing unnecessary expenses by identifying idle or underused resources.

2. Step 2: Match categories to their functions

   Security checks protect resources, Fault Tolerance improves availability, Performance enhances speed; only Cost Optimization targets unused resources.

3. Final Answer:

   Cost Optimization -> Option A

4. Quick Check:

   Idle resources = Cost Optimization [OK]

Hint: Cost Optimization finds idle resources to save money [OK]

Common Mistakes:

• Choosing Security for cost-related checks
• Confusing Fault Tolerance with cost savings
• Selecting Performance instead of Cost Optimization

3. You run AWS Trusted Advisor and see a recommendation to "Enable Multi-Factor Authentication (MFA) on root account." What will happen if you follow this advice?

medium

A. Your root account will have an extra security layer requiring a second verification step

B. Your AWS resources will automatically back up daily

C. Your billing alerts will be disabled

D. Your EC2 instances will be stopped automatically

Solution

1. Step 1: Understand MFA's function on root account

   Enabling MFA adds a second step to login, improving security by requiring a code from a device.

2. Step 2: Evaluate the effects of enabling MFA

   It does not affect backups, billing alerts, or EC2 instance states; it only secures the root user login.

3. Final Answer:

   Your root account will have an extra security layer requiring a second verification step -> Option A

4. Quick Check:

   MFA = Extra login security [OK]

Hint: MFA means extra login step for security [OK]

Common Mistakes:

• Thinking MFA triggers backups
• Assuming it disables billing alerts
• Believing it controls EC2 instance state

4. You receive a Trusted Advisor alert about "Security Groups with unrestricted access." What is the best way to fix this issue?

medium

A. Disable Trusted Advisor alerts

B. Remove rules that allow inbound traffic from 0.0.0.0/0 unless necessary

C. Open all ports to all IP addresses

D. Delete all security groups immediately

Solution

1. Step 1: Understand the risk of unrestricted access

   Allowing inbound traffic from 0.0.0.0/0 means anyone on the internet can access your resources, which is risky.

2. Step 2: Apply the best security practice

   Remove or restrict such rules to only trusted IPs or ranges; deleting all security groups or opening all ports is unsafe, and disabling alerts ignores the problem.

3. Final Answer:

   Remove rules that allow inbound traffic from 0.0.0.0/0 unless necessary -> Option B

4. Quick Check:

   Restrict open access = Fix security groups [OK]

Hint: Close open access, keep only needed IPs [OK]

Common Mistakes:

• Deleting all security groups blindly
• Opening all ports to everyone
• Ignoring alerts by disabling them

5. Your company wants to improve fault tolerance using AWS Trusted Advisor. Which recommendation should you prioritize to achieve this?

hard

A. Use AWS Trusted Advisor to identify underutilized EC2 instances

B. Disable CloudTrail logging to reduce costs

C. Open all security group ports to increase accessibility

D. Enable Amazon S3 versioning to protect data from accidental deletion

Solution

1. Step 1: Understand fault tolerance goals

   Fault tolerance means systems keep working despite failures, often by protecting data and resources.

2. Step 2: Evaluate recommendations for fault tolerance

   Enabling S3 versioning protects data by keeping copies, improving fault tolerance. Identifying underutilized instances helps cost but not fault tolerance. Opening all ports reduces security. Disabling CloudTrail removes audit logs, harming security and fault tolerance.

3. Final Answer:

   Enable Amazon S3 versioning to protect data from accidental deletion -> Option D

4. Quick Check:

   Fault tolerance = Data protection with versioning [OK]

Hint: Versioning protects data, boosting fault tolerance [OK]

Common Mistakes:

• Confusing cost savings with fault tolerance
• Opening all ports thinking it helps availability
• Disabling logging to save money
