PREPARATION
1. A project manager is defining scope for a new enterprise system. Which activity best ensures
scope clarity?
A. Assigning tasks to team members
B. Creating a detailed requirements specification document
C. Estimating project budget
D. Scheduling stakeholder meetings
Correct Answer: B. Creating a detailed requirements specification document
Rationale: A requirements specification clearly defines system expectations and boundaries, reducing
ambiguity. Assigning tasks and scheduling meetings support execution but do not define scope.
Budget estimation is financial planning, not scope definition.
2. An organization wants to improve decision-making using data. What should be the first step?
A. Purchase analytics software
B. Hire a data scientist
C. Identify key business questions
D. Build dashboards immediately
Correct Answer: C. Identify key business questions
Rationale: Effective analytics begins with defining what decisions need support. Tools and dashboards
come later. Hiring staff without defined goals or purchasing software prematurely leads to
misalignment.
3. A system outage occurs during peak hours. What is the FIRST action?
A. Notify customers
B. Begin system redesign
C. Activate incident response procedures
D. Replace affected hardware
Correct Answer: C. Activate incident response procedures
Rationale: Incident response ensures structured handling of outages. Communication and fixes follow
established protocols. Immediate redesign or hardware replacement is premature.
4. Which is the primary purpose of a firewall in an enterprise network?
A. Increase internet speed
B. Store backup data
C. Filter incoming and outgoing traffic based on rules
D. Encrypt all network traffic
Correct Answer: C. Filter incoming and outgoing traffic based on rules
Rationale: Firewalls enforce security policies by controlling traffic. They do not inherently increase
speed, store backups, or encrypt all traffic.
5. A company experiences frequent data inconsistencies. What is the most likely cause?
A. High user satisfaction
,B. Poor data governance practices
C. Excess storage capacity
D. Overstaffed IT department
Correct Answer: B. Poor data governance practices
Rationale: Data inconsistencies typically stem from weak governance, including lack of standards and
validation. Other options are unrelated to data quality.
6. What is a key benefit of cloud computing for businesses?
A. Eliminates all security risks
B. Provides unlimited physical storage
C. Offers scalable and on-demand resources
D. Requires no maintenance
Correct Answer: C. Offers scalable and on-demand resources
Rationale: Cloud systems scale resources dynamically. They do not eliminate risk or maintenance
responsibilities.
7. A team is experiencing scope creep. What is the best mitigation strategy?
A. Ignore minor changes
B. Strengthen change control processes
C. Increase project budget immediately
D. Remove stakeholders from meetings
Correct Answer: B. Strengthen change control processes
Rationale: Formal change control prevents uncontrolled scope expansion. Ignoring changes or
removing stakeholders harms project alignment.
8. What is the main purpose of risk assessment in IT projects?
A. Eliminate all risks
B. Identify and prioritize potential risks
C. Replace project planning
D. Increase project speed
Correct Answer: B. Identify and prioritize potential risks
Rationale: Risk assessment helps organizations prepare for potential issues. It does not eliminate all
risks or replace planning.
9. Which metric best measures system availability?
A. Response time
B. Uptime percentage
C. User satisfaction score
D. Number of support tickets
Correct Answer: B. Uptime percentage
Rationale: Availability is measured by uptime. Other metrics reflect performance or user experience,
not availability directly.
10. A company wants to ensure compliance with data privacy regulations. What should they
implement first?
A. Marketing policies
B. Data classification framework
C. Hardware upgrades
D. Employee bonuses
Correct Answer: B. Data classification framework
, Rationale: Classification identifies sensitive data for proper handling. Other options do not directly
ensure compliance.
11. What is the role of encryption in cybersecurity?
A. Detect malware
B. Convert data into unreadable format for unauthorized users
C. Increase processing speed
D. Monitor network traffic
Correct Answer: B. Convert data into unreadable format for unauthorized users
Rationale: Encryption protects confidentiality by encoding data. It does not detect malware or
improve speed.
12. A business wants to improve process efficiency. Which method is most appropriate?
A. SWOT analysis
B. Process mapping
C. Hiring additional staff
D. Increasing budgets
Correct Answer: B. Process mapping
Rationale: Process mapping identifies inefficiencies and bottlenecks. Staffing or budgeting does not
directly improve process visibility.
13. What is a key characteristic of Agile methodology?
A. Strict sequential phases
B. Minimal customer involvement
C. Iterative development cycles
D. No documentation required
Correct Answer: C. Iterative development cycles
Rationale: Agile emphasizes iterative delivery and feedback. It does not eliminate documentation or
customer involvement.

A. Delete old records
B. Review query optimization and indexing
C. Replace the database server
D. Disable security features
Correct Answer: B. Review query optimization and indexing

A. Increase profits
B. Ensure operations continue during disruptions
C. Reduce employee workload
D. Eliminate all risks
Correct Answer: B. Ensure operations continue during disruptions
