質問 # 65
In a Cisco ACI fabric, an endpoint moves between two leaf switches during a virtual machine migration. Which action does Cisco ACI take to minimize the impact to traffic during this event?
- A. A new leaf switch floods GARP to every other leaf switch in the fabric, which advertises a new endpoint location to the fabric.
- B. A new leaf switch sends a COOP message directly to the old leaf switch to update it with new information about the endpoint move.
- C. A new leaf switch sends a COOP message to the Cisco APIC cluster to populate a new location of the endpoint.
- D. A new leaf switch updates a COOP database on the spine, which causes the old leaf switch to install a bounce entry.
正解：D
質問 # 66
An engineer must add a group of 70 bare-metal ESXi servers to the Cisco ACI fabric, which is integrated with vCenter. These configuration steps are complete:
- The configured pool of ESXi hosts is configured with an Attachable
Access Entity Profile (AAEP) called AEP_VMM.
- The new group uses the AAEP called AEP_BAREMETAL.
Which action extends functional VMM integration to the new nodes?
- A. Implement a separate VMM domain for the bare-metal servers by using AEP_VMM.
- B. Update AAEP to AEP_VMM on all policy groups that are used toward bare-metal servers.
- C. Create a new AAEP container object for policy groups for AEP_VMM.

質問 # 69
Refer to the exhibit.
Which action should be taken to ensure authentication if the RADIUS servers are unavailable?
- A. Adjust the priority of server 10.1.1.1 to 1.
- B. Set the fallback login to local.
- C. Assign the user to the default role.
- D. Set the default login realm to LDAP
Changing the server priority is not logical answer.
The command "aaa user default-role no-login" means that remote users who do not have a user role cannot login. This means that assigning the user to default role will not be able to login.
The "aaa authentication login default" and "aaa authentication login fallback" has identical configuration. The fallback uses RADIUS server. We should change is to local.
正解：B
質問 # 70
A Cisco ACI leaf switch learns the source IP address of a packet that enters the front panel port of the switch. Which bridge domain setting is used?

- D. ARP Flooding
正解：C
質問 # 71

質問 # 74
Refer to the exhibit.
An engineer must configure an L3Out peering with the backbone network. The L3Out must forward unicast and multicast traffic over the link. Which two methods should be used to configure L3Out to meet these requirements? (Choose two.)
- A. Layer 3 routed port
- B. port channel with SVI
- C. Layer 3 routed subinterface
- D. VPC with SVI
- E. Layer 3 floating SVI

What is a requirement for Cisco ACI IPN to manage multidestination traffic?
- A. anycast gateway

- D. multicast routing
正解：D
質問 # 76
A Cisco ACI is integrated with a VMware vSphere environment. The port groups must be created automatically in vSphere and propagated to hypervisors when created in the ACI environment. Which action accomplishes this goal?
- A. Associate the VMM domain with the EPGs that must be available in vCenter.
- B. Create the port groups on the vCenter that reflect the EPG names in the APIC.
- C. Configure contracts for the EPGs that are required on the ESXi hosts.
- D. Assign the uplinks of the ESXi hosts to the vDS that the APIC created.
正解：A
質問 # 77
A Cisco ACI environment consists of multiple silent hosts that are often relocated between leaf switches. When the host is relocated, the bridge domain takes more than a few seconds to relearn the host's new location. The requirement is to minimize the relocation impact and make the ACI fabric relearn the new location of the host faster. Which action must be taken to meet these requirements?
- A. Configure ARP Flooding to Enabled.
- B. Configure IP Data-Plane Learning to No.
- C. Set Unicast Routing to Enabled.
- D. Set L2 Unknown Unicast to Hardware Proxy.
正解：A
質問 # 78
Refer to the exhibit. A client is configuring a new Cisco ACI fabric. All VLANs will be extended during the migration phase using the VPC connections on leaf switches 3, 4 and leaf switches 5,
6 toward the legacy network. The migration phase has these requirements:
- The legacy switches must be able to transfer BPDUs through the ACI
fabric.
- If the legacy switches fail to break a loop, Cisco ACI must break the loop.
Which group settings must be configured on VPC interface policy groups ipg_vpc-legacy_1 and ipg_vpc-legacy_2 to meet these requirements?
- A. MCP: disabled
BPDU Guard: enabled
BPDU Filter: enabled - B. MCP: enabled
BPDU Guard: disabled
BPDU Filter: disabled - C. MCP: disabled
BPDU Guard: disabled
BPDU Filter: enabled - D. MCP: enabled
BPDU Guard: enabled
BPDU Filter: disabled
正解：B
解説：
MCP detects loops from external sources 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. MCP works to stop Layer-2 loops, it should be enabled right away on an ACI Fabric prior to connecting Layer-2 devices for migration purposes.
