A company runs a stateful web application on two virtual machines in the same cloud region. Each VM has a public IP address. The application requires session persistence, and the team wants to distribute traffic evenly between the two VMs. They also need to detect and automatically remove a failed VM from rotation. What should they implement?

A cloud load balancer with a health probe and session affinity enabled

A pair of software load balancers installed on each VM

A DNS round-robin record pointing to both public IPs

A network security group rule that allows traffic to both VMs

An organization runs a critical database on a single virtual machine in a single availability zone. They want to increase availability without changing the application code. Which redundancy strategy should they implement?

Increase the VM size to handle more load

Deploy a second database VM in a different availability zone and configure replication

Place the VM in a different region

Which method is commonly used to implement redundancy for network links between two switches?

Enabling VLAN trunking on the switches.

Configuring a single high-speed link with a larger bandwidth capacity.

Using a firewall to filter traffic between the switches.

Link aggregation (e.g., EtherChannel) to combine multiple physical links into one logical link.

A company runs a web application on a set of VMs. They want to ensure that the application can handle sudden traffic spikes without manual intervention. They also want to avoid paying for idle resources. What should they configure?

A load balancer with a health probe

An autoscaling policy with a minimum and maximum instance count

A scheduled scaling policy that adds instances during business hours

A manual process where administrators add VMs when traffic increases
