   A video surveillance company is deploying a PowerScale cluster to store continuous 24/7 camera feeds. The workload is write-heavy with large sequential writes. The network team needs to ensure the cluster can handle the sustained write throughput. What is the most important network requirement to analyze for this workload?

   • AThe total bandwidth of the front-end network to handle the sustained write throughput.
   • BThe MTU size to reduce the number of packets for the write traffic.
   • CThe protocol used by the cameras, such as iSCSI or NFS.
   • DThe latency of the front-end network to ensure real-time processing of each frame.

   A telecommunications company is deploying a PowerScale cluster for its call detail record (CDR) processing. The CDR processing is a batch workload that runs for a few hours each night. The cluster also serves a real-time customer portal that must be responsive. The network team needs to ensure the batch workload does not impact the portal's performance. What should the Dell PowerScale designer recommend?

   • APlace the portal and CDR workloads on the same VLAN and rely on the network to handle the load.
   • BImplement QoS policies to prioritize portal traffic over CDR batch traffic.
   • CSchedule the CDR batch workload to run only when the portal is not in use.
   • DIncrease the bandwidth of the network to accommodate both workloads without QoS.

   A multi-tenant service provider is deploying a PowerScale cluster to serve multiple customers. Each customer has different performance requirements and security needs. The provider wants to isolate customer traffic and ensure that one customer's heavy workload does not impact another's latency-sensitive application. What is the most effective network design?

   • AUse separate VLANs for each customer and implement QoS policies to prioritize latency-sensitive traffic.
   • BUse a single VLAN for all customers and rely on access zones for isolation.
   • CUse separate physical networks for each customer to guarantee isolation.
   • DUse a single VLAN for all customers but implement QoS to prioritize all traffic equally.
