1. The "Maker-Checker" principle in a Core Banking Solution (CBS) environment is primarily designed to:
Allow remote access to the system.
Speed up transaction processing time.
Reduce the workload of the branch manager.
Prevent fraud and errors by ensuring no single individual can complete a transaction from start to finish.
Explanation:
The Maker-Checker principle acts as a critical internal control mechanism. It mandates that for any transaction (especially financial or sensitive data changes), there must be at least two individuals involved: one to initiate/create (Maker) and another to verify/authorize (Checker/Authorizer). This segregation of duties minimizes the risk of internal fraud, unauthorized transactions, and human error.
2. In a banking environment, a "Data Warehouse" is primarily used for:
Storing cheque images only.
Historical data analysis, reporting, and decision support (OLAP).
Real-time transaction processing (OLTP).
Connecting ATMs to the network.
Explanation:
While the Core Banking System handles day-to-day transactions (OLTP), the Data Warehouse stores historical data from various sources to facilitate analysis, MIS reporting, and strategic decision-making (OLAP).
3. In a Core Banking Solution (CBS), what is the primary function of the "Parameter File"?
To store employee attendance records.
To generate daily balance sheets.
To store customer transaction data.
To define rules and configurations (e.g., interest rates, product codes) that drive the software's behavior.
Explanation:
Parameter files act as the rulebook for the CBS. Changes in interest rates or product features are made here without altering the source code, allowing flexibility.
4. What is "Day End Process" (EOD) in a CBS system?
Turning off the servers.
A system process to validate transactions, calculate interest, update GL, and generate reports for the day.
Closing the branch shutters.
Sending staff home.
Explanation:
EOD is a critical batch process that runs at the end of the business day to ensure all transactions are posted, accounts balanced, and system date is moved to the next working day.
5. Which identifier is unique to every customer in a CBS system and links all their accounts?
CIF / Cust ID
Cheque Number
Transaction ID
Account Number
Explanation:
The Customer Information File (CIF) or Customer ID is the unique key assigned to a customer. Multiple accounts (Savings, Loan, FD) are linked to this single CIF to provide a 360-view of the customer relationship.
6. Why is "Batch Processing" used for interest application in CBS?
It allows processing large volumes of accounts simultaneously during off-peak hours.
It is required by law.
It requires manual calculation.
It is the only way to calculate interest.
Explanation:
Interest calculation for millions of accounts is resource-intensive. Batch processing runs this as a background job (usually at night) to avoid slowing down the system during banking hours.
7. What is the difference between "Data Warehousing" and "Data Mining" in banking?
Warehousing is the process of compiling and organizing data into one common database; Mining is the process of extracting meaningful patterns from that data.
Mining happens before Warehousing.
They are the same thing.
Warehousing is searching for patterns; Mining is storing data.
Explanation:
A Data Warehouse acts as a central repository of integrated historical data. Data Mining uses algorithms on this warehoused data to discover hidden patterns, correlations, and insights (e.g., predicting which customers are likely to default or identifying cross-selling opportunities).
8. What is the role of a "Delivery Channel Interface" in a CBS?
It delivers physical cheque books.
It calculates interest.
It connects the bank employees to the database.
It connects the CBS to external channels like ATM, Internet Banking, and Mobile Banking.
Explanation:
The Delivery Channel Interface allows transactions initiated at various touchpoints (ATMs, Phones) to be routed to the Core Banking System for processing and response.
9. In CBS security, the principle of "Least Privilege" means:
Managers have no privileges.
Users are given maximum access to all modules.
Users are granted only the minimum levels of access necessary to perform their job functions.
Customers have the least priority.
Explanation:
This principle ensures that a teller can only access cash modules, while a loan officer accesses loan modules, preventing unauthorized access and potential fraud.
10. Banks typically host their Core Banking Solution in a "Tier 4" Data Center. What does Tier 4 imply?
Low security but high speed.
Data stored in the cloud only.
99.995% availability with 2N+1 redundancy (Fault Tolerant).
99.671% availability with single path for power.
Explanation:
Data Centers are rated from Tier 1 to Tier 4 based on uptime and redundancy. Tier 4 is the highest standard, offering Fault Tolerance (no single point of failure), independent dual-powered cooling/power paths, and 99.995% uptime guarantee, crucial for 24x7 banking operations.
11. As per RBI guidelines on Outsourcing of IT Services, banks CANNOT outsource which of the following functions?
Core Management functions (like policy formulation and internal audit).
Application testing.
ATM maintenance.
Data entry work.
Explanation:
RBI allows outsourcing of non-core activities (like IT support, hardware maintenance). However, Core Management Functions , including decision-making regarding credit, policy formulation, internal audit, and compliance, cannot be outsourced as it compromises the bank's control and accountability.
12. In Business Continuity Planning, "Recovery Point Objective" (RPO) defines:
The maximum acceptable amount of data loss measured in time.
The time taken to switch to the DR site.
The cost of data recovery.
The maximum time allowed to recover the system.
Explanation:
RPO determines how much data the bank can afford to lose in a disaster. For example, if RPO is 15 minutes, it means backups must be done every 15 minutes, so at most 15 minutes of data is lost. Zero RPO means real-time data replication.
13. In an Open Banking architecture, what is the function of an "API Gateway"?
To store customer passwords.
To act as a single entry point for managing, securing, and routing API calls between external apps and internal banking systems.
To provide physical cash.
To generate monthly statements.
Explanation:
The API Gateway sits between the outside world (Fintech apps) and the bank's core systems. It enforces security (authentication, rate limiting), traffic management, and analytics for all incoming API requests.
14. What is "User Acceptance Testing" (UAT) in CBS implementation?
Final phase of testing done by actual end-users (bank staff) to verify if the system meets business requirements before going live.
Testing done by developers.
Testing the hardware speed.
Testing by the RBI.
Explanation:
UAT is crucial to ensure the software handles real-world scenarios correctly. It validates the business logic and usability from the perspective of the people who will actually use the system.
15. The "Begin of Day" (BOD) process in CBS ensures:
That the date is changed to the current working date and the system is ready for transactions.
That the vault is open.
That all reports are printed.
That all staff have logged in.
Explanation:
BOD is a mandatory process run before any transaction can take place. It updates the system date, checks system health, and enables transaction posting for the new day.
16. In CBS implementation, "Big Bang Migration" refers to:
Moving all branches and data to the new system simultaneously in one go.
Moving data branch-by-branch over a year.
Moving only savings accounts first.
An explosion in the server room.
Explanation:
Big Bang involves switching the entire bank to the new system at once (usually over a weekend). It is riskier but faster than the Phased approach.
