Cisco 300-620 Dumps Questions Answers

To extend the EPG-100 to the vCenter as a port group with a tagged VLAN ID of 100, the following actions should be taken:

Define a static VLAN range (from 100-200) under a VLAN pool: This step involves creating a VLAN pool that includes the desired VLAN range. The VLAN pool is then associated with the VMM domain that corresponds to the vCenter integration1.

Associate the dc1vcdev domain with EPG: The VMM domain named ‘dc1vcdev’ should be associated with the EPG-100. This association allows for the automatic creation of port groups in vCenter when the EPG is associated with a VMM domain1.

Select the appropriate settings for the domain association:

Untagged VLAN Access: This should be unselected because the VLAN ID needs to be tagged.

VLAN Mode: Set to ‘Static’ to specify the encapsulation VLAN ID.

Encap: Set to ‘100’ to define the specific VLAN ID that should be tagged for the port group1.

To divert traffic between VM-1 and VM-2 using a Multi-Node service graph while preventing an insufficient number of available Layer 4 to Layer 7 devices in the first cluster, the following configuration set should be used:

PBR node tracking: This feature monitors the health of the nodes (Layer 4 to Layer 7 devices) in the service graph. If a node becomes unavailable, the system can take action based on the tracking threshold1.

Tracking threshold with action bypass: When the number of healthy nodes falls below the tracking threshold, the action ‘bypass’ ensures that traffic is not sent to the unhealthy nodes, thus preventing service disruption1.

Symmetric PBR: This ensures that return traffic follows the same path as the original traffic, maintaining session consistency and avoiding asymmetric routing issues1.

Resilient hashing: This hashing mechanism provides a consistent and optimal distribution of traffic across the available Layer 4 to Layer 7 devices, even when the number of nodes changes due to a failure or maintenance1.
