   How does the Round Robin load-balancing algorithm distribute network traffic across links in a PowerScale configuration?

   • AIt sends all traffic to the link with the lowest current utilization.
   • BIt sends each new packet or connection to the next link in a cyclic order.
   • CIt sends traffic to a single link until it fails, then switches to the next.
   • DIt sends traffic based on the source IP address hash.

   In a PowerScale network configuration, when would you typically enable Forward Error Correction (FEC)?

   • AWhen connecting nodes in the same rack with short cables.
   • BWhen using link aggregation to increase bandwidth.
   • CWhen using low-speed links (e.g., 1GbE) to reduce latency.
   • DWhen using high-speed links (e.g., 25GbE or 100GbE) over longer distances where signal degradation is possible.

   A media company is deploying a PowerScale Gen 6 cluster with 100 GbE connections over a long-distance fiber link between two data centers. They are experiencing occasional bit errors that cause retransmissions and performance degradation. Which feature should they enable on the network interfaces to reduce the impact of these errors?

   • AForward Error Correction (FEC) to detect and correct bit errors without retransmission.
   • BJumbo frames to reduce the number of packets and thus the number of errors.
   • CRound Robin load balancing to distribute traffic across multiple links and reduce the error impact.
   • DLink aggregation with LACP to combine multiple fibers and reduce the error rate per link.

   When comparing PowerScale Gen 5 and Gen 6 network architecture, which statement accurately describes a key difference?

   • AGen 6 eliminates the need for link aggregation because individual ports are fast enough.
   • BGen 6 supports higher link speeds and more ports per node, enabling higher aggregate bandwidth than Gen 5.
   • CGen 5 uses a separate management network, while Gen 6 combines management and data traffic on the same physical ports.
   • DGen 5 supports only 1GbE links, while Gen 6 supports 10GbE links.

   What is the primary purpose of link aggregation in a PowerScale network configuration?

   • ATo replace the need for a switch by connecting nodes directly to each other.
   • BTo assign a separate IP address to each physical link for management purposes.
   • CTo combine multiple physical links into a single logical link, increasing bandwidth and providing redundancy.
   • DTo encrypt all traffic between nodes and clients.
