   A cloud service provider is deploying ECS to offer object storage to external customers. The service must handle high concurrency with many small objects (e.g., 10–50 KB). The network team needs to ensure low latency for these small object operations. Which design consideration is most important?

   • APlace all ECS nodes on the same subnet to reduce routing hops.
   • BUse a single high-bandwidth link for all client traffic.
   • CEnsure the load balancer distributes requests evenly across ECS nodes to avoid hot spots.
   • DMaximize the MTU to 9000 bytes to reduce overhead for small objects.

   A government agency is deploying ECS and requires that only the storage administrators' workstations (on 192.168.10.0/24) can access the ECS management interface. All other traffic to the management interface must be blocked. Which security control should be implemented?

   • AUse a VPN for all management access and do not restrict by source IP.
   • BConfigure an ACL on the management VLAN that permits only source IPs from 192.168.10.0/24 and denies all other traffic.
   • CPlace the management interface on a public subnet and rely on a firewall to allow only the admin subnet.
   • DDisable the management interface on all nodes and use the storage network for management.
