Question 1 of 30

During a critical peak sales period for a rapidly growing online retailer, the MySQL 8.0 database powering the e-commerce platform begins to exhibit severe performance degradation. User complaints about slow page loads and failed transactions surge, directly impacting revenue. The database administrator, Elara, must restore system stability swiftly and effectively without causing prolonged downtime or data corruption. Elara suspects the performance issues are linked to an unexpected increase in complex analytical queries from a newly deployed marketing analytics tool, coupled with a surge in typical transaction volume. Which of the following strategies would be the most prudent and effective initial course of action for Elara to mitigate the crisis and restore optimal performance?

Systematically monitor database activity, identify the most resource-intensive queries and processes using diagnostic tools, and apply targeted optimizations such as index adjustments, query rewriting, or configuration tuning based on the findings.
Initiate an immediate rollback of the recent marketing analytics tool deployment and revert the database to its state prior to the tool's integration.
Provision additional hardware resources, including more powerful CPUs and increased RAM, to the database server to alleviate the performance bottleneck.
Temporarily disable non-essential database features and background maintenance tasks to reduce the immediate load on the system.
