NEW QUESTION # 75
When Cisco ACI connects to an outside Layers 2 network, where does the ACI fabric flood the STP BPDU frame?
- A. within the access encap VLAN
- B. within the APIC
- C. within the bridge domain
- D. between all the spine and leaf switches
Answer: C
Explanation:

NEW QUESTION # 76
An engineer needs to avoid loops in the ACI network and needs an ACI leaf switch to error- disable an interface if the interface receives an ACI-generated packet. Which action meets these requirements?
- A. Change the default administrative state of the global MCP Instance Policy.
- B. Enable the Loop Indication by MCP event in the Error Disabled Recovery Policy.
- C. Uncheck the Loop Protection Action check box in MCP Instance Policy.
- D. Set Rogue EP Control in the Endpoint Controls Policy.
Answer: A
Explanation:
MisCabling Protocol (MCP) detects loops from external sources (i.e., misbehaving servers, external networking equipment running STP, etc.) and will err-disable the interface on which ACI receives its own packet. Enabling this feature is a best practice, and it should be enabled globally and on all interfaces, regardless of the end device.
For MCP to be enabled, you need to have it enabled globally and on a per-interface basis. While MCP is enabled on all interfaces by default, it is not turned "on" until you also enable it globally.
The global configuration knob for MCP can be enabled by configuring the global settings here:
Fabric > Access Policies > Global Policies > MCP Instance Policy default.

NEW QUESTION # 77
Refer to the exhibit.
An engineer wants to initiate an ICMP ping from Server1 to Server2. The requirement is for the BD1 to enforce ICMP replies that follow the expected path. The packets must be prevented from taking the direct path from Leaf1 to Server1. Which action must be taken on BD1 to meet these requirements?
- A. Set L2 Unknown Unicast to Flood.
- B. Disable Unicast Routing.
- C. Set L2 Unknown Unicast to Hardware Proxy.
- D. Enable ARP Flooding.
Answer: C
Explanation:
In the Cisco ACI environment, when an engineer wants to enforce a specific path for ICMP replies and prevent packets from taking a direct path, setting Layer 2 Unknown Unicast to Hardware Proxy on the bridge domain (BD1) is the appropriate action. This setting ensures that the unknown unicast traffic, which includes ICMP packets destined for an unknown MAC address, is forwarded to the spine proxy. The spine proxy then forwards the packets based on the endpoint table information, ensuring that the packets follow the expected path through the fabric and do not take any shortcuts or direct paths that bypass the intended routing.
NEW QUESTION # 78
Drag and Drop Question
An engineer must configure VMM domain integration on a Cisco UCS B-Series server that is connected to a Cisco ACI fabric. Drag and drop the products used to create VMM domain from the bottom into the sequence in which they should be implemented at the top. Products are used more than once.
Answer:
Explanation:
Explanation:
1. Create a dynamic VLAN pool. From the APIC user interface, choose Fabric > Access Policies > Pools > VLAN > Create VLAN Pool.
2. From the APIC user interface, choose Virtual Networking > VMM Domains > VMware > Create vCenter Domain.
3. On the vCenter interface, create a vShield contoller(vShield is a third party produt and we do here an simple OVA deployment. We use vCenter to install a VM)
4. On the vCenter interface, verify that the VMware DVS is created

NEW QUESTION # 79
What must be enabled in the bridge domain to have the endpoint table learn the IP addresses of endpoints?
- A. L2 unknown unicast: flood
- B. subnet scope
- C. unicast routing
- D. GARP based detection
Answer: C
Explanation:
To have the endpoint table learn the IP addresses of endpoints in a bridge domain, unicast routing must be enabled1. This allows the bridge domain to learn the IP addresses of endpoints through the data plane1.
