Which three statements about ACI border leaf are true? (Choose 3)

A.    Only 32 border leaves are supported in an ACI fabric.
B.    Any ACI leaf can be a border leaf/ there is not limitation in the number of leaf switches that can be used as border leaves.
C.    The border leaf can also be used to connect to compute, IP storage, and service appliances.
D.    The border leaves are dedicated leaf switches that support only layer 2 and layer 3 out in an ACI fabric.
E.    The border leaves are ACI leaves that provide Layer 3 connections to outside networks.

Answer: BCE
Explanation:
Border Leaves
The border leaves are ACI leaves that provide layer 3 connections to outside networks. Any ACI leaf can be a border leaf. These can also simply be called leaf switches. There is no limitation in the number of leaf switches that can be used as border leaves. The border leaf can also be used to connect to compute, IP storage, and service appliances. In large-scale design scenarios it may be preferred to have border leaf switches separated from the leaves that connect to compute and service appliances for scalability reasons.

QUESTION 56
Which three statements are considered best practice when configuring an NFS appliance port on Cisco UCS? (Choose 3)

A.    If storage is configured in active/passive mode and both fabric interconnects require communication to the same controller, then the appliance port VLANs should be allowed on the upstream switches.
B.    Cisco UCS supports static and link aggregation control protocol port channels for appliance port configuration. However, no virtual port channel support.
C.    If storage and servers are located are located in the same subnets, then the appliance port VLSNA should be allowed on the upstream switch.
D.    Use of the same VLAN for multiple storage protocol traffic is highly recommended to conserve VCLAN namespace use.
E.    If storage must be accessed outside of the cisco UCS domain, then the appliance port VLANs should be allowed on the upstream switch.
F.     Configuration of the VLAN tagging on the storage side and on the Cisco UCS side simultaneously is recommended.

Answer: ACE
Explanation:
Why Appliance Port VLANs Should be Allowed on Uplinks
There are number of reasons why an upstream switch should allow storage appliance port traffic. These include:
If storage must be accessed outside of the UCS domain.
If storage and servers are located in different subnets.
If storage is configured in Active/Passive mode and both fabric interconnects require
communication to the same controller.
In certain failover scenarios.
