Exam 300-620 topic 1 question 219 discussion

Resolution Immediacy: Pre-provision: Policies are downloaded to the leaf switch software even before a VM controller is attached to the virtual switch (e.g., a VMware vSphere Distributed Switch). This pre-provisions the configuration on the switch. Immediate: Policies are downloaded to the leaf switch software as soon as an ESXi host attaches to the DVS. On-demand: Policies are pushed to the leaf switch software when an ESXi host attaches to the DVS and a VM is placed in the port group. Deploy Immediacy: Immediate: Policies are programmed into the hardware policy CAM as soon as they are downloaded in the leaf software. On-demand: Policies are programmed into the hardware policy CAM only when the first packet is received through the data path. This optimizes hardware space utilization.

*On Demand Deployment Immediacy: When the "On Demand" attribute is selected in the Deploy Immediacy feature during VMM domain association to an EPG, the policy is not immediately pushed to the leaf switches. Instead, the EPG policy is downloaded to the leaf switch only when it is required, such as when a virtual machine (VM) is connected to a port group associated with the EPG. *Behavior: This approach optimizes resource usage by avoiding unnecessary programming of hardware resources (e.g., CAM entries) until they are needed. D-The EPG policy is programmed in the hardware policy CAM only when the first packet is received through the data path: This describes "Resolution Immediacy," not "Deploy Immediacy."

Sorry, wrong answer. It is A!

It is defintitely D! Specifies that the policy is programmed in the hardware policy CAM as soon as the policy is downloaded in the leaf software

The deployment immediacy option specifies that the policy should be programmed in the hardware policy cam only when the switch receives a packet through the data path. This setting helps optimize the hardware space.
