An engineer applies this QoS policy to a Cisco Nexus 9000 switch in a data center. After applying the policy, storage traffic (iSCSI) is experiencing high latency and occasional drops. The engineer verifies that the iSCSI traffic is not matching the 'BulkData' class. What is the most likely cause of the issue?","explanation":"ISCSI is a latency-sensitive storage protocol that requires a strict priority queue to ensure low latency and minimal jitter. Without a priority queue configured in the policy-map, iSCSI traffic competes with other traffic classes on a best-effort basis, leading to high latency and drops even if it is not matching the 'BulkData' class.","domainId":"e22aadfc-3eb5-4358-882b-e64f27181adf","difficulty":"hard","questionType":"multiple_choice","pbqConfig":null,"exhibitText":"Refer to the exhibit.\n\n\n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n","options":[{"id":"66e269b8-055a-4859-89fb-e272ac9fc486","label":null,"text":"The policy-map does not specify a priority queue for latency-sensitive traffic.","isCorrect":true},{"id":"29307fcd-6057-4da9-98e7-e54ba8e7de7c","label":null,"text":"The policy-map is applied at the system level, but iSCSI traffic is not classified under any class-map.","isCorrect":false},{"id":"c465943b-7f3b-4dad-9241-2a4929fe6da9","label":null,"text":"The bandwidth percent for class-default is too low, causing iSCSI to be starved.","isCorrect":false},{"id":"c8e09959-a572-4bba-9a21-cfcc36968200","label":null,"text":"The class-map 'BulkData' does not match the correct traffic because the match statement uses qos-group instead of dscp.","isCorrect":false}],"domainName":"Compute","domainSlug":"dccor-compute"},{"id":"7c60eccf-1f6e-4161-a935-e722076a4f2b","slug":"which-type-of-zoning-uses-the-world-wide-port-name-wwpn-to-utm7b","questionText":"Which type of zoning uses the World Wide Port Name (WWPN) to define zone members, providing better security because WWPNs are globally unique?","explanation":"Hard zoning by WWPN uses WWPNs to define members, and is considered more secure than soft zoning by port.","domainId":"fc4d65dd-2e3d-4ce2-af05-de60f53567f3","difficulty":"easy","questionType":"multiple_choice","pbqConfig":null,"exhibitText":null,"options":[{"id":"3d3235ff-a041-4285-be98-37ee131e93e0","label":null,"text":"Soft zoning by port","isCorrect":false},{"id":"0fb48c38-5f96-4bd6-8e7a-0c6e7782c883","label":null,"text":"VSAN-based zoning","isCorrect":false},{"id":"80b31437-4e1c-4263-865c-535db871f309","label":null,"text":"Hard zoning by WWPN","isCorrect":true},{"id":"f9c64a88-b411-4b37-b034-c6956e4c83cc","label":null,"text":"LUN masking","isCorrect":false}],"domainName":"Storage Network","domainSlug
