Oracle ASM Essentials Quiz Quiz

1. Definition of Oracle ASM

   Which statement best describes Oracle ASM (Automatic Storage Management)?

   1. A specialized storage manager that automates database file management
   2. A network protocol for database communication
   3. A type of cloud computing service
   4. A programming language for database applications
   5. A backup utility for data warehouses

2. ASM vs. Traditional File System

   How does Oracle ASM differ from a traditional file system used in databases?

   1. ASM cannot handle multiple disks at once
   2. ASM is used exclusively for networking
   3. Traditional file systems support redundancy, whereas ASM does not
   4. ASM automates storage management and striping, while traditional file systems require manual management
   5. Traditional file systems provide automatic disk repair, but ASM does not

3. ASM Key Benefit

   Which is a key benefit of using Oracle ASM for managing database storage?

   1. Increases CPU clock speed
   2. Automatic file placement and balanced loading across disks
   3. Provides email notification for queries
   4. Encrypts user passwords
   5. Replaces database authentication

4. ASM Architecture Components

   What are the primary architectural components of Oracle ASM?

   1. GUI designer and web server
   2. Network hub and firewall
   3. ASM instance and ASM disk groups
   4. Query processor and data archiver
   5. Backup server and log collector

5. ASM Instance Role

   What is the main role of the ASM instance in Oracle ASM?

   1. To execute SQL statements
   2. To generate reports
   3. To manage disk group metadata and coordinate with the database instance
   4. To send emails to administrators
   5. To handle user authentication

6. Disk Group Creation

   How are ASM disk groups created in Oracle ASM?

   1. By updating user permissions
   2. By adding one or more disks together and configuring them with a redundancy level
   3. By setting a network IP address only
   4. By installing additional CPUs
   5. By connecting external backups

7. Disk Group Management

   How does Oracle ASM manage data within an ASM disk group?

   1. It stores each file on a single disk only
   2. It compresses files into zip archives
   3. It disables automatic storage allocation
   4. It stripes and mirrors files automatically based on configured redundancy
   5. It deletes unused files daily

8. ASM Redundancy Types

   Which of the following is an ASM redundancy level for disk groups?

   1. Backup redundancy
   2. Ultra redundancy
   3. Encrypted redundancy
   4. Normal redundancy
   5. Hidden redundancy

9. Disk Failure Handling

   How does Oracle ASM handle the failure of a disk within a disk group?

   1. It moves the database to another network
   2. It automatically recovers data using mirrored copies
   3. It stops the entire database
   4. It locks the server indefinitely
   5. It deletes all data from other disks

10. ASM Rebalancing

    When does rebalancing in Oracle ASM typically occur?

    1. After every five minutes, regardless of changes
    2. During every SQL query
    3. When disks are added to or removed from a disk group
    4. Whenever users log in
    5. Only during server shutdown
