Database Backup Procedures! Trivia Questions Quiz

1. Which of the following is designed to identify entry of nonexistent customer account number?

Sequence check

Field check

Validity check

Completeness check

A validity check is designed to identify the entry of a nonexistent customer account number. It ensures that the data entered into a system is valid and meets certain criteria. In this case, the validity check would verify if the customer account number entered actually exists in the system's database. This helps to prevent errors or fraudulent entries by cross-checking the entered data against a valid list of customer account numbers.

2. Which backup method is the fastest?

Full daily backup

Incremental daily backup

Differential daily backup

Complete daily backup

The incremental daily backup method is the fastest because it only backs up the data that has changed since the last backup, rather than backing up the entire set of data every time. This means that less data needs to be transferred and stored, resulting in faster backup times.

3. Which of the following statements is true?

Concurrent update controls are designed to facilitate restoration of backups

Use of VPN protects the confidentiality of information while it is being transmitted over the internet

Cross-footing balance tests are effective method for detecting entry of invalid account number

Emergency changes to information systems don`t need to be formally approved and documented

The use of VPN (Virtual Private Network) is a security measure that encrypts data and creates a secure connection between the user and the internet. This ensures that the information being transmitted over the internet remains confidential and protected from unauthorized access. VPNs are commonly used by individuals and organizations to safeguard their data and maintain privacy while using public networks or accessing sensitive information remotely.

Checkpoint

Restoration

A copy of the state of a database at a specific point in time during the middle of a normal business day is called a checkpoint. A checkpoint is used to ensure data integrity and consistency by recording the current state of the database and its transaction log. It allows for recovery in case of system failure or data corruption, as the checkpoint serves as a reference point to restore the database to a consistent state.

5. Backup procedures are relevant to which Trust Service framework principle?

Confidentiality

Privacy

Processing integrity

Availability

Backup procedures are relevant to the availability principle in the Trust Service framework. Availability refers to ensuring that systems and data are accessible and usable by authorized individuals when needed. Backup procedures help to ensure the availability of data by creating copies of it that can be restored in the event of a system failure, data loss, or other disruptions. By regularly backing up data, organizations can minimize downtime and ensure that critical information is readily available, contributing to the overall availability of systems and services.
