   A streaming media company is deploying ECS to serve video content to millions of users. The workload is read-heavy with large files, and the company needs to maximize throughput while minimizing latency for users. The network team has 100 GbE links available for the storage network. Which configuration is most effective for this workload?

   • AUse multiple 100 GbE links with link aggregation and enable jumbo frames.
   • BUse a single 100 GbE link with QoS to prioritize video traffic.
   • CUse standard MTU and rely on the load balancer to distribute traffic.
   • DUse a single 100 GbE link for all storage traffic to simplify management.

   A video surveillance company is deploying ECS to store continuous camera footage. The workload is write-heavy with large sequential writes. The network team has 10 GbE links available. Which configuration is most likely to improve write throughput for this workload?

   • ADisable TCP offload on the ECS nodes to reduce CPU usage.
   • BEnable jumbo frames (MTU 9000) on all ECS and switch interfaces in the storage path.
   • CUse a single VLAN for all storage traffic to reduce switching overhead.
   • DConfigure the ECS nodes to use a smaller MTU (1500) to reduce latency.

   A financial services firm is deploying ECS in its data center. The compliance team requires that storage replication traffic between two ECS sites must be isolated from all other traffic, and that management access to the ECS nodes must be restricted to a specific administrative subnet. Which network topology design satisfies both requirements?

   • AUse a single flat VLAN for all ECS traffic and rely on ACLs to restrict management access.
   • BConfigure replication over the management network to reduce cabling and use IPsec for encryption.
   • CPlace all ECS interfaces on the same subnet and use firewall rules between the sites.
   • DCreate a dedicated replication VLAN between sites and a separate management VLAN with an ACL allowing only the admin subnet.

   In an ECS network topology, what is the primary reason for separating data and management traffic onto different VLANs or subnets?

   • ATo improve performance and security by isolating traffic types
   • BTo reduce the number of switches required
   • CTo allow clients to access management interfaces directly
   • DTo simplify IP addressing by using the same subnet

   What is the purpose of using link aggregation (e.g., bonding multiple NICs) in an ECS node?

   • ATo provide redundancy and increased bandwidth
   • BTo reduce network latency
   • CTo increase the number of IP addresses
   • DTo simplify VLAN configuration
