True
false

Answer 1

Answer:

True

Explanation:

Answer 2

A multi-AZ DB will have a little downtime, and a single AZ will be unavailable during the scaling operation. - True

• A multi-AZ (Availability Zone) database deployment in Amazon Web Services (AWS) offers more availability and fault tolerance than a single AZ database configuration.
• AWS automatically replicates the data to a standby database in a different AZ when utilising a multi-AZ database.
• The standby database automatically takes over in the event of a primary database breakdown or outage, reducing downtime.
• When doing scheduled database maintenance or scaling activities, there can be a brief period of downtime.
• A single AZ database deployment, on the other hand, lacks automated failover features, therefore in the event of a failure, the database won't be accessible until a manual intervention is made.
