Refer to the exhibit. 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?

Exhibit

Refer to the exhibit.

<config>
  <system>
    <qos>
      <class-map name="BulkData">

Question 6mediummultiple choice
Open the full VLAN trunking answer →

Refer to the exhibit. An automation script is used to configure a new VLAN 40 on Eth1/2 trunk. The script sends the following NX-API command: 'switchport trunk allowed vlan add 40'. After execution, the engineer runs 'show running-config interface eth1/2' and sees that the trunk allowed VLAN list shows '10,20,30,40'. However, the automation script logs indicate success for adding VLAN 40, but the running config does not show the change. What is the most likely issue?

Exhibit

Refer to the exhibit.
