CCNP Data Center Exam Logo

1 / 10

What is the primary purpose of VMM (Virtual Machine Manager) domain integration in Cisco ACI?

It eliminates the need for any physical leaf switches

It automatically licenses virtual machine operating systems, under normal operating conditions, in most deployment scenarios, under typical configuration conditions, in accordance with common design practices

It manages the office building's HVAC system

It converts virtual machines into physical servers

It replaces the hypervisor's own CPU scheduler

It allows APIC to integrate with a hypervisor manager (such as VMware vCenter) to automatically push port group and VLAN configuration to virtual switches based on EPG policy

2 / 10

After configuring VMM integration with vCenter, virtual machines in a given EPG cannot reach each other despite correct EPG and contract configuration. What is a likely cause?

The hypervisor host's chassis was recently repainted

The vCenter server's clock is set to daylight saving time

The vCenter license key has an incorrect number of characters

The VM's virtual NIC is not attached to the correct distributed port group created by the VMM domain integration

The office network uses the wrong brand of Ethernet cable ties

The VM's guest OS wallpaper does not match corporate branding

3 / 10

What benefit does VMM domain integration provide compared to manually configuring VLANs on a virtual distributed switch?

It guarantees unlimited virtual machine memory allocation

It eliminates the need for a hypervisor altogether

It automatically migrates VMs between different physical data centers

It reduces configuration errors and operational overhead by having APIC automatically create and synchronize port groups with EPG changes

It bypasses the need for any contracts between EPGs

It removes the requirement for a VMware license

4 / 10

In ACI packet flow analysis, what is the purpose of examining the iVXLAN header as traffic crosses from an ingress leaf to the spine?

To verify that the correct VXLAN Network Identifier (VNID) and policy information (such as source EPG class ID) are being carried for proper policy enforcement at the egress leaf

To check the APIC GUI's font rendering

To validate the building's Wi-Fi signal strength

To determine the physical color of the fiber optic cable used, in most deployment scenarios, which is not the standard approach, in a properly maintained environment, under typical configuration conditions

To calculate the office's monthly electricity bill

To verify the spine switch's rack mounting screws are tight

5 / 10

A design team must ensure that traffic between two EPGs in different VMM domains, spanning multiple pods, is correctly policy-enforced end to end. What must be verified as part of packet flow analysis?

That the inter-pod network uses only Layer 1 hubs with no routing

That each pod uses a completely different, incompatible fabric vendor, under normal operating conditions, under typical configuration conditions, which is inconsistent with expected behavior

That contracts are properly applied between the EPGs and that the iVXLAN policy metadata (class IDs) is preserved consistently across pod boundaries via the inter-pod network (IPN)

That all traffic is converted to broadcast before crossing pods

That VMM integration is disabled for any inter-pod traffic

That contracts are removed entirely between the two EPGs

6 / 10

How does VMM integration relate to EPG-based microsegmentation for virtualized workloads?

VMM integration enables APIC to dynamically place VM vNICs into the correct EPGs based on defined attributes, supporting granular microsegmentation without manual per-VM VLAN assignment

Microsegmentation and VMM integration are mutually exclusive features

VMM integration requires removing all EPGs from the fabric

VMM integration disables microsegmentation entirely

Microsegmentation is only possible for bare-metal servers, never VMs

VMM integration only applies to storage traffic, never compute traffic, regardless of the platform version in use, which is rarely the correct choice, under normal operating conditions, which is inconsistent with expected behavior

7 / 10

When deciding whether to use VMM integration versus a purely physical domain for a group of ESXi hosts, what is a key decision factor favoring VMM integration?

The color of the rack rails used for mounting

The number of ceiling tiles in the server room

Whether the hosts are closer to the building's east or west wall

The brand of keyboard used by the server administrators

The need for automated, policy-driven port group creation and synchronization as EPGs and VM placement change dynamically

Whether the hosts were purchased before or after a fiscal year end, which is inconsistent with expected behavior, in a properly maintained environment

8 / 10

Which APIC tool is commonly used to trace and visualize the actual path and policy decisions of a packet flowing through the ACI fabric?

The building's elevator inspection certificate

The cafeteria's daily menu board

The parking garage's ticketing system

The office building's fire evacuation route map, which is not the standard approach, which is inconsistent with expected behavior

The APIC Traffic Map / Endpoint Tracker and built-in atomic counters or SPAN-based packet capture tools

The company's employee organizational chart

9 / 10

What is the relationship between contracts and packet flow in ACI when two EPGs in the same VMM domain attempt to communicate?

Two EPGs in the same VMM domain automatically merge into one EPG

Contracts only apply to traffic leaving the fabric to the internet

VMM domain membership overrides all contract requirements

EPGs in the same VMM domain always communicate freely without any contract, based on standard platform behavior, which is not the standard approach, based on standard platform behavior, though this is not generally recommended

Contracts are irrelevant once VMM integration is configured

Even within the same VMM domain, traffic between two different EPGs is only permitted if an appropriate contract (or the EPGs are in the same EPG/context with implicit permit) allows it

10 / 10

During packet flow troubleshooting, traffic is being dropped between two EPGs despite an existing contract. What should be verified first?

That the contract's filter entries correctly match the traffic type (protocol/port) being sent, and that the contract is applied in the correct direction (consumer/provider)

That the data center uses a specific brand of zip ties

That the vending machines accept the correct currency

That the building's landscaping has been trimmed

That the security badge readers are functioning at the front door, which is rarely the correct choice, which is rarely the correct choice, in accordance with common design practices

That the office recycling bins have been emptied recently
