A PowerFlex cluster is experiencing performance degradation during peak hours. The administrator adds a new SDS node to improve performance. After the addition, the administrator notices that performance has not improved and, in some cases, has worsened. What is the most likely cause?

The cluster's redundancy factor was reduced during the addition, causing data to be less protected.

The new node is not being used because it was added to the wrong storage pool.

Data rebalancing is consuming resources, temporarily reducing performance.

The new node has a slower CPU than the existing nodes, causing a bottleneck.

What is the primary purpose of adding a node to an existing PowerFlex cluster?

To change the cluster's redundancy factor from 2 to 3

To replace a failed node without any impact on the cluster

To upgrade the software version of the entire cluster

To increase the cluster's storage capacity and/or compute resources

Which of the following is a method for adding a node to a PowerFlex cluster?

Using the 'addnode' command in the operating system shell

Using the 'powerflex' command-line utility

Using PowerFlex Manager's 'Add Nodes' wizard

Using the 'scaleio' command-line utility

Which of the following is a prerequisite that must be verified before adding a node to a PowerFlex cluster?

The node's operating system is supported by PowerFlex

The node is already configured with the same hostname as an existing node

The node has a public IP address

The node has been added to the cluster's DNS server

A PowerFlex cluster is running a critical workload with a redundancy factor of 2. The administrator needs to add a new SDS node, but the cluster is already at 90% capacity. The addition will trigger data rebalancing. What is the most important prerequisite to verify before proceeding?

The new node has the same hardware configuration as the existing nodes.

The new node is added to a separate storage pool to avoid rebalancing.

The cluster's redundancy factor is temporarily reduced to 1 during the addition.

The cluster has enough free space to accommodate the rebalancing without causing a 'no space' condition.
