A company has a load balancer distributing traffic to a pool of web servers. They notice that one server is frequently unavailable due to maintenance. The load balancer continues to send traffic to that server, causing errors. Which configuration should be implemented to prevent this?

Manually remove the server from the pool during maintenance.

Configure health checks on the load balancer to automatically remove unhealthy servers from the pool.

Increase the timeout value on the load balancer.

Use round-robin scheduling instead of least-connections.

An organization is setting up a two-node failover cluster for a line-of-business application. The application writes data to a shared disk. The IT team must ensure that both nodes can access the same data after a failover. Which configuration is required?

Use local storage on each node and replicate data in real time.

Assign the same IP address to both nodes.

Configure shared storage that is accessible by both cluster nodes.

Install the application on both nodes but use separate databases.

A company runs a critical database on a single server. The database must remain available if the server hardware fails. The IT team wants to implement a solution that automatically switches to a standby server without manual intervention. Which approach should they choose?

Install redundant power supplies and RAID in the existing server.

Create a scheduled backup job that restores the database to a standby server every hour.

Set up a load balancer in front of two database servers with active-active replication.

Configure a failover cluster with shared storage and automatic failover.
