When adjusting cluster-level resources to accommodate increased workloads, what does scaling CPU and memory allocations involve?

Physically replacing the CPUs in all cluster nodes

Disabling power management features on all nodes

Modifying the resource limits and reservations for virtual machines or containers

Changing the cluster's network subnet to increase bandwidth

Which action is part of the software configuration when adding a new node to a PowerEdge XE cluster?

Disabling the node's management controller to reduce overhead

Assigning the node a unique cluster name that differs from the naming convention

Applying the same firmware and driver versions as the existing cluster nodes

Installing a different operating system to provide diversity

Which action is an example of scaling storage allocations in a PowerEdge XE cluster?

Changing the cluster's failover policy

Expanding a virtual disk or adding storage capacity to a storage pool

Modifying the cluster's DNS settings

Updating the cluster's firmware

Which method is commonly used to rebalance workloads across cluster nodes after expansion?

Deleting workloads from overloaded nodes

Shutting down underutilized nodes to force workloads to move

Live migration of virtual machines or containers to less utilized nodes

Increasing the CPU frequency on overloaded nodes

A research lab runs a PowerEdge XE cluster with 8 nodes for HPC workloads. The lab is adding a new workload that requires 40% more compute capacity. The admin has verified that the power and cooling infrastructure can support additional nodes, and the network switches have spare ports. The cluster uses a shared storage array with adequate capacity. What is the NEXT step the admin should take before physically installing the new nodes?

Verify that the cluster software license supports the total number of nodes after expansion

Check that the new nodes have the same firmware and driver versions as the existing nodes

Install the operating system on the new nodes before racking them

Run a workload rebalancing script on the existing nodes to free up capacity
