Explanation
The best strategy to ensure wayward vehicle traffic does not interfere with datacenter operations is to install bollards. Bollards are sturdy posts that are installed around a perimeter to prevent vehicles from entering or crashing into a protected area. Bollards can provide physical security and deterrence for datacenters that are located near busy roads or parking lots. Bollards can also prevent accidental damage or injury caused by vehicles that lose control or have faulty brakes.

This is the best solution to increase the speed of the NIC because link aggregation is a technique that combines multiple physical network interfaces into a single logical interface. This can increase the bandwidth, redundancy, and load balancing of network traffic. Link aggregation requires both the server and the switch to support it and be configured accordingly.

A database server is a server that hosts a database management system (DBMS) that stores, organizes, and manipulates data. A database server is suitable for housing customer sales records, as it can provide fast and secure access, query and analysis capabilities, backup and recovery options, and scalability and performance optimization. Some examples of database servers are Microsoft SQL Server, Oracle Database, MySQL, and PostgreSQL. Verified Reference: [What is a Database Server?]

RTO stands for Recovery Time Objective and it is a metric that defines the maximum acceptable amount of time that a system or service can be unavailable after a disaster or disruption. RTO is part of the business continuity planning and disaster recovery planning processes. RTO ensures a guarantee of the amount of time it will take to restore a downed service by setting a target or goal for recovery. RTO can vary depending on the criticality and priority of the service.
