This practice exam simulates the ISTQB Advanced Level Technical Test Analyst (CTAL-TTA) certification exam. It contains 45 multiple-choice questions covering all chapters of the CTAL-TTA syllabus with emphasis on white-box test techniques, static and dynamic analysis, and technical quality characteristics.

Exam Details:

• Time allowed: 120 minutes
• Passing score: 65% (approximately 51 points out of 78)
• Question types: Multiple choice with varying point values (K2, K3, K4 levels)

Exam Instructions

Read each question carefully. Pay attention to key words:

• MOST appropriate - Multiple options may be correct; choose the best fit
• FIRST - Sequence matters; choose the initial action
• PRIMARY - Main purpose, not secondary benefits
• NOT - Inverse questions; find the false statement

Question Point Values:

• K2 (Understand): 1 point
• K3 (Apply): 2 points
• K4 (Analyze): 3 points

Time Management:

• Average 2.5 minutes per question
• Mark difficult questions and return later
• Don't leave questions unanswered (no negative marking)

If you missed questions on coverage:

Statement Coverage Practice:

def grade(score):
    result = "F"           # S1
    if score >= 90:        # S2
        result = "A"       # S3
    elif score >= 80:      # S4
        result = "B"       # S5
    elif score >= 70:      # S6
        result = "C"       # S7
    return result          # S8

Calculate: How many tests for 100% statement coverage? Answer: 4 tests (score values: 95, 85, 75, 65 to hit S3, S5, S7, and the implicit else)

MC/DC Technique

For decision if (A and B) or C:

Step 1: List all conditions: A, B, C

Step 2: Find independence pairs for each:

• A independent: (A=T, B=T, C=F)=T vs (A=F, B=T, C=F)=F
• B independent: (A=T, B=T, C=F)=T vs (A=T, B=F, C=F)=F
• C independent: (A=F, B=F, C=T)=T vs (A=F, B=F, C=F)=F

Step 3: Minimum test set: 4 tests (N+1 where N=3)

Static vs Dynamic Analysis

Quick Reference:

Security Testing

OWASP Top 10 Quick Review:

1. Injection - SQL, command, LDAP injection
2. Broken Authentication - Session management flaws
3. Sensitive Data Exposure - Encryption failures
4. XXE - XML external entity attacks
5. Broken Access Control - Authorization failures
6. Security Misconfiguration - Default credentials
7. XSS - Cross-site scripting
8. Insecure Deserialization - Object manipulation
9. Vulnerable Components - Outdated libraries
10. Insufficient Logging - Lack of audit trails

Performance Testing Types

Key Concepts to Review

Coverage Hierarchy

Multiple Condition Coverage (strongest)
          |
Modified Condition/Decision Coverage (MC/DC)
          |
Condition/Decision Coverage
        /   \
Branch Coverage   Condition Coverage
       |
Statement Coverage (weakest)

Cyclomatic Complexity Formula

V(G) = Decision Points + 1

Risk levels: 1-10 (low), 11-20 (moderate), 21-50 (high), 51+ (very high)

Additional Study Resources

Before Taking Another Practice Exam

1. Review the ISTQB CTAL-TTA Syllabus - Ensure you understand all learning objectives
2. Practice coverage calculations by hand - Don't rely on tools
3. Work through MC/DC examples - Build independence pair tables
4. Understand tool categories - Know what each type detects
5. Review security concepts - OWASP categories and testing methods

Recommended Study Order

Common Exam Mistakes

Mistake 1: Confusing Coverage Types

Wrong: Thinking 100% condition coverage ensures 100% branch coverage Right: Condition and branch coverage don't imply each other - use Condition/Decision coverage for both

Mistake 2: MC/DC Calculation Errors

Wrong: Thinking MC/DC requires all 2^N combinations Right: MC/DC typically needs only N+1 tests (show independence for each condition)

Mistake 3: Static vs Dynamic Confusion

Wrong: Expecting static analysis to find memory leaks Right: Memory leaks require runtime observation (dynamic analysis)

Mistake 4: Complexity Interpretation

Wrong: Treating cyclomatic complexity as lines of code Right: Complexity = decision points + 1 = minimum tests for branch coverage

Mistake 5: Security Testing Types

Wrong: Confusing SAST and DAST Right: SAST = static (code review), DAST = dynamic (running application)
