   A telecom provider is deploying ECS and needs to proactively detect network issues that could impact storage performance. The operations team wants to be alerted when the storage network experiences high latency or packet loss. Which monitoring approach is most effective for this requirement?

   • AEnable NetFlow on the core router to analyze traffic patterns.
   • BUse ICMP ping to the ECS management IP every 5 minutes.
   • CConfigure SNMP traps on the storage switches for interface errors and high utilization.
   • DMonitor only the ECS node CPU and memory utilization.

   When designing an IP addressing scheme for an ECS cluster, which consideration is most important for the data network?

   • AAssigning static IP addresses only to management interfaces
   • BUsing a /30 subnet to minimize broadcast traffic
   • CUsing the same subnet as the management network to simplify routing
   • DEnsuring the subnet has enough addresses for all nodes and client access

   A national research lab is deploying a 6-node ECS cluster. The application generates a mix of large sequential reads (for analysis) and small random writes (for metadata updates). The lab requires that the storage network maintains high throughput for the large reads while keeping latency low for the small writes. The network team has 25 GbE links available. Which design best balances these conflicting requirements?

   • AConfigure separate VLANs for read and write traffic, with jumbo frames on the read VLAN and standard MTU on the write VLAN.
   • BUse jumbo frames on all interfaces and rely on the load balancer to distribute both read and write traffic evenly.
   • CEnable QoS to prioritize write traffic over read traffic on the same VLAN.
   • DUse standard MTU (1500) on all interfaces to minimize latency for both read and write traffic.
