質問 # 218
An EPG is associated with a VMM domain. Which option must be set to allow the bridge domain and the VRF of the EPG to be instantiated on all leaf switches that discovered the ESXi host?

A. On-Demand Deployment immediacy
B. On-Demand Resolution immediacy
C. Immediate Resolution immediacy
D. Immediate Deployment immediacy

正解：A

解説：
Setting the EPG's Deployment immediacy to On-Demand ensures that the bridge domain and VRF are only pushed down to - and instantiated on - the leaf switches that actually see the ESXi host, rather than all leaves up front.

質問 # 226
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 Session Logs and Audit Logs to the monitor policy.
B. Add Faults and Events 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.

正解：A

解説：
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.

質問 # 227
A customer must upgrade the Cisco ACI fabric to use a feature from the new code release. However, there is no direct path from the current release to the desired one. Based on the Cisco APIC Upgrade/Downgrade Support Matrix, the administrator must go through one intermediate release.
Which set of steps must be taken to upgrade the fabric to the new release?

A. Upgrade the APICs to an interim release.
Upgrade the switches to an interim release.
Upgrade the APICs to the targeted release.
Upgrade the leaf and spine switches to the targeted release.
B. Upgrade the APICs to an interim release and then switches to an interim release.
When all switches are operational, upgrade leaf switches to the targeted release.
Upgrade the spine switches to the targeted release.
Upgrade the APICs to the targeted release.
C. Upgrade the APICs directly to the targeted release.
Upgrade the switches to an interim release.
When all switches are operational, upgrade the leaf switches to the targeted release.
Upgrade the spine switches to the targeted release.
D. Upgrade the APICs to an interim release.
Upgrade the leaf switches directly to the targeted release.
Upgrade the spine switches directly to the targeted release.
Upgrade the APICs to the targeted release.

正解：A

解説：
When upgrading the Cisco ACI fabric through an intermediate release, the following steps should be taken:
Upgrade the APICs to an interim release: This is the first step to ensure that the APICs are running a stable version that is compatible with both the current and the targeted release1.
Upgrade the switches to an interim release: After the APICs are upgraded, the next step is to upgrade the leaf and spine switches to the same interim release. This ensures that the entire fabric is running on a compatible version before moving to the targeted release1.
Upgrade the APICs to the targeted release: Once the fabric is stable on the interim release, the APICs can be upgraded to the targeted release. It's important to verify that the APICs are fully operational before proceeding to upgrade the switches1.
Upgrade the leaf and spine switches to the targeted release: The final step is to upgrade the leaf and spine switches to the targeted release. This should be done after the APICs have been successfully upgraded and are stable on the targeted release1.
By following these steps, the customer can successfully upgrade the Cisco ACI fabric to the new code release that includes the desired feature.

質問 # 228
Which tenant is used when configuring in-band management IP addresses for Cisco APICs, leaf nodes, and spine nodes?

A. common
B. default
C. mgmt
D. infra

正解：D

質問 # 229
In the context of VMM, which protocol between ACI leaf and compute hosts ensures that the policies are pushed to the leaf switches for immediate and on demand resolution immediacy?

A. VXLAN
B. STP
C. ISIS
D. LLDP

正解：D

解説：
In the context of VMM, the protocol between ACI leaf and compute hosts that ensures that the policies are pushed to the leaf switches for immediate and on-demand resolution immediacy is LLDP (Link Layer Discovery Protocol)2. LLDP is used for discovery and to ensure that the policies are applied as needed for the virtual machines2.

質問 # 230
What two actions should be taken to deploy a new Cisco ACI Multi-Pod setup? (Choose two.)

A. Connect all spines to the IPN.
B. Increase interface MTU for all IPN routers to support VXLAN traffic.
C. Configure the TEP pool of the new pod to be routable across the IPN.
D. Configure anycast RP for the underlying multicast protocol
E. Configure MP-BGP on IPN routers that face the Cisco ACI spines.

正解：B、C

解説：
When deploying a new Cisco ACI Multi-Pod setup, it's crucial to ensure that the Tunnel Endpoint (TEP) pool of the new pod is routable across the Inter-Pod Network (IPN). This allows the TEP addresses to be reachable across the pods, facilitating communication between them. Additionally, increasing the Maximum Transmission Unit (MTU) for all IPN routers is necessary to support the larger frame size required by VXLAN encapsulation, which is typically above the standard Ethernet MTU of 1500 bytes.

質問 # 231
Refer to the exhibit. An engineer must disable the communication between the two backup servers in the backup EPG. Which action accomplishes this goal?

A. Set Intra EPG Isolation to Enforced.
B. Set a different static binding for the encap VLAN.
C. Set the physical domain to None.
D. Set Preferred Group Member to Excluded.

正解：A

質問 # 232
Which two statements regarding ACI Multi-Site are true? (Choose two.)

A. The Inter-Site network routers should run OSPF to establish peering with the spines.
B. Routers in the Inter-Site network must run OSPF, DHCP relay, and MP-BGP.
C. The Multi-Site orchestrator must be directly attached to one ACI leaf.
D. ACI Multi-Site is a solution that allows one APIC cluster to manage multiple ACI sites.
E. ACI Multi-Site is a solution that supports a dedicated APIC cluster per site.

正解：D、E

解説：
The two true statements regarding ACI Multi-Site are:
ACI Multi-Site is a solution that supports a dedicated APIC cluster per site1.
ACI Multi-Site is a solution that allows one APIC cluster to manage multiple ACI sites1.

質問 # 233
What happens to the traffic flow when the Cisco ACI fabric has a stale endpoint entry for the destination endpoint?

A. The leaf switch sends the traffic to the wrong destination leaf.
B. The leaf switch drops the traffic that is destined to the endpoint.
C. The leaf switch does not learn the source endpoint through data plane learning.
D. The leaf switch floods the traffic to the endpoint throughout the fabric.

正解：B

質問 # 234
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. Add the VMM domain under the AEP_BAREMETAL AAEP object.
C. Create a new AAEP container object for policy groups for AEP_VMM.
D. Update AAEP to AEP_VMM on all policy groups that are used toward bare-metal servers.

正解：B
