JAIIB Paper 2 Module C Quiz 1

Correct answer: Option 4. Data mining uses analytical methods to discover patterns in data, such as unusual transaction behaviour or customer trends. Topic area: Bank Computerisation — Data mining.

Correct answer: Option 3. Redundancy supports availability by providing alternate components, links or systems if one fails. It must be designed and tested rather than assumed. Topic area: Bank Computerisation — Redundancy in IT infrastructure.

Correct answer: Option 4. A firewall permits or blocks network traffic according to defined rules. It is one layer of defence and does not replace endpoint security, monitoring or access controls. Topic area: Bank Computerisation — Network firewall.

Correct answer: Option 1. Encryption at rest protects stored information on disks, databases or backups. Access to encryption keys must also be controlled. Topic area: Bank Computerisation — Encryption at rest.

Correct answer: Option 3. Backups support recovery from accidental deletion, corruption, hardware failure and some cyber incidents. Restore testing is essential to confirm that backups work. Topic area: Bank Computerisation — Database backup.

Correct answer: Option 4. A disaster recovery site supports continuity of critical technology services when the primary environment is unavailable. Recovery objectives and periodic drills matter. Topic area: Bank Computerisation — Disaster recovery site.

Correct answer: Option 4. RPO expresses how far back data may need to be recovered after disruption, such as a tolerable 15-minute data gap. Topic area: Bank Computerisation — RPO (Recovery Point Objective).

Correct answer: Option 2. RTO is the target duration for restoring a service after disruption. It differs from RPO, which concerns the tolerable data-loss window. Topic area: Bank Computerisation — RTO (Recovery Time Objective).

Correct answer: Option 2. Integrity concerns the accuracy and completeness of data. Controls include validation, authorisation, audit trails and reconciliation. Topic area: Bank Computerisation — Data integrity.

Correct answer: Option 2. Availability is one part of the confidentiality-integrity-availability triad. Resilience, redundancy, backups and recovery planning support it. Topic area: Bank Computerisation — Availability in information security.

Correct answer: Option 4. Confidentiality means information is disclosed only to authorised people or systems. Access controls and encryption help protect it. Topic area: Bank Computerisation — Information security confidentiality.

Correct answer: Option 4. In client-server architecture, client applications request services and servers process requests or provide shared resources. Topic area: Bank Computerisation — Client-server architecture.

Correct answer: Option 2. Latency is delay, not throughput. High latency can make online banking feel slow even when the network can carry substantial data. Topic area: Bank Computerisation — Network latency.

Correct answer: Option 4. MFA combines different factor categories, such as something known, possessed or inherent. Two passwords alone are not genuinely different factor categories. Topic area: Bank Computerisation — Multi-factor authentication (MFA).

Correct answer: Option 2. RBAC maps permissions to roles and helps enforce least privilege. Roles should be reviewed when duties change. Topic area: Bank Computerisation — Role-based access control (RBAC).

Correct answer: Option 1. CBS maintains customer/account information centrally or through an integrated system, enabling transactions at connected branches and channels to update the same account records. Topic area: Bank Computerisation — Core Banking System (CBS).

Correct answer: Option 2. A UPS bridges short power interruptions and can protect equipment from power fluctuations. It does not replace generators, backups or disaster-recovery arrangements. Topic area: Bank Computerisation — Uninterrupted Power Supply (UPS).

Correct answer: Option 3. A LAN connects computers and devices within a limited area, such as a branch or office. Wide-area networks connect geographically distant sites. Topic area: Bank Computerisation — Local Area Network (LAN).

Correct answer: Option 4. A WAN connects networks over large geographic distances, allowing branches and data centres to communicate securely. Topic area: Bank Computerisation — Wide Area Network (WAN).

Correct answer: Option 4. A data warehouse integrates data from multiple sources and structures it for analysis, reporting and decision support. It is not itself an ATM or payment network. Topic area: Bank Computerisation — Data warehouse.
