   In a PowerScale cluster configured with failover LACP, what is the primary benefit of using LACP instead of static link aggregation?

   • ALACP automatically detects link failures and redistributes traffic to remaining links.
   • BLACP eliminates the need for a switch configuration.
   • CLACP provides higher bandwidth than static aggregation.
   • DLACP assigns a unique IP address to each link for load balancing.

   An organization is migrating from a PowerScale Gen 5 cluster to a Gen 6 cluster. They have a requirement to support 400 GbE connectivity for future growth. They also need to ensure high availability with failover LACP. Which network configuration should they plan for?

   • AUse Round Robin load balancing across multiple 100 GbE links without LACP, because it provides both load sharing and failover.
   • BUse multiple 40 GbE links with LACP on Gen 5 nodes, because Gen 5 supports 400 GbE via link aggregation.
   • CUse multiple 100 GbE links with LACP on Gen 6 nodes, because Gen 6 supports higher-speed interfaces and LACP for redundancy.
   • DUse a single 400 GbE link without LACP, because Gen 6 supports 400 GbE natively and LACP is not needed for redundancy.

   In a PowerScale cluster, what happens to network traffic when one physical link in a link aggregation group fails?

   • ATraffic is redistributed across the remaining links in the group, maintaining connectivity.
   • BThe cluster automatically reboots the node to restore the link.
   • CAll traffic stops until the failed link is replaced.
   • DTraffic is rerouted through a different VLAN on the same link.

   A PowerScale cluster uses a link aggregation group with two 10 GbE links. The administrator wants to use Round Robin load balancing to distribute traffic. What is a critical requirement for Round Robin to work effectively?

   • AThe switch must support LACP in active mode.
   • BThe links must be connected to different switches for redundancy.
   • CThe cluster must be running Gen 6 hardware.
   • DAll links in the aggregation group must have the same speed and duplex settings.

   A company is planning to deploy a PowerScale Gen 6 cluster and needs to choose between using 25 GbE and 100 GbE interfaces. They have a mix of workloads: some require high bandwidth for large file transfers, and others require low latency for small I/O operations. Which network configuration would best meet these diverse requirements?

   • AUse 100 GbE interfaces for all nodes, because they provide the highest bandwidth and lowest latency.
   • BUse 25 GbE interfaces for all nodes, because they are sufficient for most workloads and are more cost-effective.
   • CUse 100 GbE interfaces with FEC enabled, because FEC reduces latency for small I/O operations.
   • DUse a mix of 25 GbE and 100 GbE interfaces, with 100 GbE for nodes that handle large file transfers and 25 GbE for nodes that handle small I/O operations.
