A Solutions Architect is asked to design two data centers based on Cisco ACI technology that can extend L2/L3, VXLAN, and network policy across locations. ACI Multi-Pod has been selected. Which two requirements must be considered in this design? (Choose two.) A. ACI underlay protocols, i.e. COOP, IS-IS and MP-BGP, spans across pods. Create QoS policies to make sure those protocols have higher priority.
B. A single APIC Cluster is required in a Multi-Pod design. It is important to place the APIC Controllers in different locations in order to maximize redundancy and reliability.
C. ACI Multi-Pod requires an IP Network supporting PIM-Bidir.
D. ACI Multi-Pod does not support Firewall Clusters across Pods. Firewall Clusters should always be local.
E. Multi-Pod requires multiple APIC Controller Clusters, one per pod. Make sure those clusters can communicate to each other through a highly available connection. Answer: BC
Explanation:
Multipod is with only a single APIC cluster - multisite requires multiple clusters.
"The entire network hence runs as a single large fabric from an operational perspective; however, ACI Multi-Pod introduces specific enhancements to isolate as much as possible the failure domains between Pods, contributing to increase the overall design resiliency. This is achieved by running separate instances of fabric control planes (IS-IS, COOP, MP-BGP) across Pods."

An engineer must implement management policy and data plane separation in the Cisco ACI fabric. Which ACI object must be created in Cisco APIC to accomplish this goal? A. Application profile
B. Tenant
C. Contract
D. Bridge domain Answer: B
Explanation:
An ACI tenant is a secure and exclusive virtual computing environment that forms a unit of isolation from a policy perspective but does not represent a private network.
If you investigate further into use cases for tenants in the real world, you will find that tenants are often deployed in order to achieve these two technical controls:
- Administrative separation
- Configuration fault isolation QUESTION 119
An engineer is implementing a Cisco ACI environment that consists of more than 20 servers. Two of the servers support only Cisco Discovery Protocol with no order link discovery protocol. The engineer wants the servers to be discovered automatically by the Cisco ACI fabric when connected. Which action must be taken to meet this requirement? A. Create an override policy that enables Cisco Discovery Protocol after LLDP is enabled in the default policy group.
B. Configure a higher order interface policy that enables Cisco Discovery Protocol for the interface on the desired leaf switch.
C. Configure a lower order policy group that enables Cisco Discovery Protocol for the interface on the desired leaf switch.
D. Create an interface profile for the interface that disables LLDP on the desired switch that is referenced by the interface policy group. Answer: A
Explanation:
A leaf interface override policy allows interfaces that have interface policy group assignments to apply an alternate interface policy group.
Imagine that a group of ports have been configured on Node 101, using a specific interface policy group.
One of the interfaces connects to a firewall, and security policies dictate that LLDP and CDP toward the firewall need to be disabled on all firewall-facing interfaces.
It might be impossible to modify the interface policy group associated with the port because it might be part of a port block.
In this case, a leaf interface override can be used to assign an alternative interface policy group to the port of interest. QUESTION 120
An engineer wants to monitor all configuration changes, threshold crossing, and link-state transitions in a Cisco ACI fabric. Which action must be taken to receive the required messages? A. Add Faults and Events to the monitor policy.
B. Add Session Logs and Audit Logs to the monitor policy.
C. Include Audit Logs and Events in the Syslog source policy.
D. Include Events and Session Logs in the Syslog source policy. Answer: B
Explanation:
After searching, there is nothing called "syslog source policy" in ACI. Syslog source policy exists in UCS Central. The choices now are on "Monitoring Policy" that exits on A and C.

 QUESTION 121
An organization has encountered many STP-related issues in the past due to failed hardware components. They are in the process of long-term migration to a newly deployed ACI fabric. Senior engineers are worried that spanning-tree loops in the existing network may be extended to the ACI fabric. Which feature must be enabled on the ACI leaf ports to protect the fabric from spanning-tree loops? A. BPDU Guard
B. per-VLAN MCP
C. Storm Control
D. BPDU Filter Answer: B
Explanation:
A Layer 2 loop does not impact the stability of an ACI fabric because ACI can broadcast traffic at line rate with little need to process the individual packets.
Layer 2 loops, however, can impact the ability of endpoints to process important traffic.
For this reason, mechanisms are needed to detect loops resulting from miscabling and misconfiguration.
One of the protocols ACI uses to detect such externally generated Layer 2 loops is MisCabling Protocol (MCP).
MCP is disabled in ACI by default. To enable MCP, you must first enable MCP globally and then ensure that it is also enabled at the interface policy level.
As part of the global enablement of MCP, you define a key that ACI includes in MCP packets sent out on access ports.
If ACI later receives an MCP packet with the same key on any other port, it knows that there is a Layer 2 loop in the topology.
In response, ACI can either attempt to mitigate the loop by disabling the port on which the MCP protocol data unit was received or
it can generate a system message to notify administrators of the issue.

A network engineer must design a method to allow the Cisco ACI to redirect traffic to the firewalls. Only traffic that matches specific L4-L7 policy rules should be redirected. The load must be distributed across multiple firewalls to scale the performance horizontally. Which action must be taken to meet these requirements? A. Configure ACI Service Graph with Unidirectional PBR.
B. Implement ACI Service Graph with GIPo.
C. Implement ACI Service Graph Two Nodes with GIPo.
D. Configure ACI Service Graph with Symmetric PBR. Answer: D

An engineer created two interface protocol policies called Pol_CDP40275332 and Pol_LLDP46783451.
The policies must be used together in a single policy. Which ACI object must be used? A. interface policy group
B. switch policy group
C. switch profile
D. interface profile Answer: A
Explanation:
LLDP and CDP can be used on the same interface.
A CDP policy will be created like this:
Fabric > Access Policies > Policies > Interface > CDP Interface > <create Your policy>
A LLDP policy will be created like this:
Fabric > Access Policies > Policies > Interface > LLDP Interface > <create Your policy>
Both policies are independant to each other and can be applied within an Interface Policy Group
Fabric > Access Policies > Interfaces > Leaf Interfaces > Policy Group > Leaf Access Port > <Your policy here > > <set a CDP and a LLDP policy within Your interface policy group>
An interface profile will be used to create an interface selector.
The interface selector has physical ports and also calls Your interface policy group.

Which action must be taken to meet these requirements?
 A. Enable ARP Flooding
B. Set L2 Unknown Unicast to Flood
C. Set IP Data-Plane Learning to No
D. Enable Unicast Routing Answer: B

An engineer must ensure that Cisco ACI flushes the appropriate endpoints when a topology change notification message is received in an MST domain.
Which three steps are required to accomplish this goal? (Choose three.) A. Enable the BPDU interface controls under the spanning tree interface policy.
B. Configure a new STP interface policy.
C. Bind the spanning tree policy to the switch policy group.
