Which two deployment architectures could you use for scaling-out database reads?

• A. Adding a memcached-tier for caching data and objects in RAM to reduce the number of times an external data source must be read.
• B. Altering the storage engine for all tables to memory to increase performance.
• C. Changing the system setting with memory stickiness to true in order not to swap out mysq1dfrom memory.
• D. Implementing a three-node, single-primary InnoDB Cluster.
• E. Edit the configuration file and increase the value for parallel_read_workers and reboot the server

You want to create an encrypted table. So, you enter this command:
CREATE TABLE 'test_encryption2% (
'id' int(10) unsigned NOT NULL AUTO_INCREMENT,
'server_name' varchar(15) NOT NULL,
PRIMARY KEY ('id') ) ENGINE=MYISAM AUTO_INCREMENT=l DEFAULT CHARSET=latin1 ENCRYPTION = 'Y1; You receive the following error:
ERROR 1031 (HY000): Table storage engine for 'test_encryption2' doesn't have this option Which statement correctly explains the reason for this error?

• A. The test_encryption2 already exist. You are not using the correct option to recreate it and it is causing the error.
• B. You cannot use the AUTO_INCREMENT option to create an encrypted table. This is what is causing the error.
• C. The term "server_name" is a reserved MySQL term. You cannot use it for the new table. This is what is causing the error.
• D. The encryption feature only works with InnoDB tables. You are creating a MylSAM table, and it is causing the error.

• B. Create user by using CREATE USER 'newuser'@'localhost' IDENTIFIED WITH 'Sh@256Pa33';
• C. Add default_authentication_plugin=sha256_password under [mysqld] in the configuration file.

You are testing a new application and want to use data masking but the database is empty. What option will generate dummy data for you to use for testing?
