質問 # 79
An existing Cisco ACI Multi-Site setup with default fabric settings contains endpoints that communicate with an MTU of 1500. What is the minimum MTU value that must be supported by the ISN to allow control plane endpoint information exchange between sites?
- A. 0
- B. 1
- C. 2
- D. 3
正解：A
解説：
By default, the spine nodes generate 9000-byte packets to exchange endpoint routing (i.e MP- BGP) information.

質問 # 85
An engineer configures Cisco ACI Multi-Site and must specify the control plane TEP IP for spines. Which statement describes control plane TEP IP in this situation?
- A. The unique IP address is defined on each spine node that belongs to a fabric and is used to establish MP-BGP EVPN and VPNv4 adjacencies with the spine nodes in remote sites.
- B. The common anycast address is shared by all the spine nodes in the same site and is used to perform headend replication for BUM traffic.
- C. The unique IP address is defined on each spine node that belongs to a fabric and is used to establish VXLAN adjacencies with the spine nodes in remote sites.
- D. The common anycast address is shared by all the spine nodes at the same site and is used lo source and receive unicast VXLAN data plane traffic.
正解：A
解説：
The control plane TEP (Tunnel Endpoint) IP address is a unique IP address assigned to each spine node within a Cisco ACI fabric. This IP address is used to establish MP-BGP EVPN (Multiprotocol Border Gateway Protocol Ethernet VPN) and VPNv4 (VPN version 4) adjacencies with the spine nodes in remote sites when configuring Cisco ACI Multi-Site. The control plane TEP IP enables the spine nodes to exchange routing information and network reachability for seamless integration of multiple sites into a single ACI fabric.

質問 # 87
What is a use of the Overlay Multicast TEP in Cisco ACI Multi-Site communication?
- A. to send and receive unicast VXLAN data plane traffic
- B. to perform headend replication
- C. to establish MP-BGP adjacencies with remote spines
- D. to act as the source IP for BUM traffic
正解：B
解説：
Overlay Multicast TEP (O-MTEP): This common anycast address is shared by all the spine nodes in the same site and is used to perform head-end replication for BUM traffic. BUM traffic is sourced from the O-UTEP address defined on the local spine nodes and destined for the O- MTEP of remote sites to which the given bridge domain is being stretched.
