DEE-1421 Subnet Practice Questions

A company’s HPC environment is using Dell EMC Isilon Gen 6 nodes. They have additional throughput requirements and have asked for your recommendations. The environment consists of two subnets: Mgmt-subnet: 1x1-GigE interface in the “mgmt-pool” for management traffic on a VLAN-tagged management network in an Isilon default System Access zone. Data-subnet: 2x10-GigE aggregated interfaces in the “data-pool” for data traffic on a VLAN-tagged data network in an Isilon user-defined data Access Zone Which recommendation should be provided?

• AA. Remove VLAN tagging from the network
• BB. Move the data pool into the System Access zone
• CC. Use different groupnets for management and data traffic
• DD. Use only one subnet and pool for both the management and data traffic

A company has a cluster with two subnets. The first subnet has 1GbE interfaces dedicated for management and the second subnet has 10GbE interfaces dedicated for handling all data access. When the cluster started serving the production environment, poor performance was observed while the data is accessed through the data subnet. While troubleshooting the network the administrator discovered that the return traffic is going through the management network. Which recommended solution will resolve this issue?

• AA. Configure static routes for both subnets
• BB. Enable source-based routing
• CC. Enable destination based routing with static routes
• DD. Change the gateway priorities
