Oracle MySQL 2021 Implementation Essentials Sample Questions:

1. You establish MySQL Enterprise Server on Oracle Cloud Infrastructure connection via Secure Shell (SSH).
When accessing a new MySQL Enterprise Edition Oracle Cloud Infrastructure (OCI) instance, you want to use MySQL Enterprise Workbench for SQL and remote management.
What are two ways to successfully configure Workbench based on the MySQL access credentials?

A) Convert the private key to ppk format first. Based on TCP/IP over SSH and based on the created private key, opc-user, and MySQL access credentials, you can access the MySQL CS instance.
B) Configure the MySQL Router first and based on those settings, you access your MySQL CS instance.
C) Open the MySQL OCI instance access port 3306. For the MySQL connection, you use this port, and, in addition, you configure the remote management based on SSH based on the provided key.
D) Configure TCP/IP over SSH and based on the created private key, opc-User, and MySQL access credentials, you can access the MySQL OCI instance.

2. An existing MySQL Database environment has been doing backup and restore in a logical way by using the mysq1dump and mysq1 client utilities.

A) mysqlbackup from MySQL Enterprise Backup allows logical backup with concurrency built in to get faster backup speed and restoration speed.
