Which of the following are required characteristics of database servers in high transaction environments? (Select THREE).
Click on the arrows to vote for the correct answer
A. B. C. D. E. F. G.BCD.
The correct answers are B. High bandwidth, D. Load balancing, and F. Hotswappable drives.
A. Two-factor authentication: Two-factor authentication is a security feature that verifies a user's identity through two authentication methods. Although it is an essential security feature for any server, it is not a requirement specifically for database servers in high transaction environments.
B. High bandwidth: In high transaction environments, the database server must be able to handle a large volume of data traffic. High bandwidth ensures that the server can transmit data quickly and efficiently, which is essential for database servers in high transaction environments.
C. Higher RPM drives: Hard disk drive (HDD) rotational speed is measured in revolutions per minute (RPM). Higher RPM drives can process data more quickly than lower RPM drives. Although it is an important factor for database servers, it is not a required characteristic for database servers in high transaction environments.
D. Load balancing: Load balancing distributes traffic across multiple servers to ensure that no single server is overwhelmed. In high transaction environments, load balancing is necessary to ensure that the database server can handle the volume of data traffic. It is a required characteristic for database servers in high transaction environments.
E. High latency: Latency is the delay between the time a request is sent and the time a response is received. In high transaction environments, low latency is critical to ensure that the database server can respond quickly to requests. High latency is not a required characteristic for database servers in high transaction environments.
F. Hotswappable drives: Hotswappable drives can be replaced while the server is running, without requiring a shutdown. In high transaction environments, hotswappable drives are necessary to ensure that the server can continue to operate even if a drive fails. It is a required characteristic for database servers in high transaction environments.
G. Encryption: Encryption is a security feature that protects data by converting it into a code that is unreadable without a decryption key. Although it is an important security feature for any server, it is not a required characteristic specifically for database servers in high transaction environments.
