A. Ensure that the newly instead card's MAC addresses are present in the DHCP configuration for ZTP.
B. Set the virtual Chassis as auto-provisioned before the line cars are inserted.
C. Configure the auto-sw-update parameter on the VCF before inserting new line cards.
D. Set the Virtual Chassis as per-provision before the line are inserted.

正解：A

質問 4：
An EVPN-signaled VXLAN overlay has been deployed in the network shown in the exhibit. Host1 is a bare metal server, and is dual-homed to the network. The IP addresses 10.1.1.1/24 and 10.1.1.2/24 are assigned to the same physical NIC, and no virtualization is configured on the server.

In this scenario, which two statements are true? (Choose two.)
A. The MAC address associated with 10.1.1.1/24 and 10.1.1.2/24 will be same when advertised to leaf3.
B. The ESI assigned to the host1 link must be the as the ESI assigned to the leaf2 host1 link.
C. Traffic from IP address 10.1.1.1/24 must traverse the VXLAN network to reach IP address 10.1.1.2/24
D. The connection host1 to devices leaf1 and leaf2 must be configuration a LAG.
正解：B,D

B. This spine device has three neighboring leaf devices.
C. This spine device will not install any routes for remote destinations in its routing table.
D. This spine device has three neighboring spine devices.

A. Configure a spine-to-spine EVPN peering as part of the routing instance.
B. Configure proxy-macip-advertisement under the IRB interface.
C. Configure a spine-to-spine BGP peering as part of the overlay.
D. Configure virtual-gateway-accept-data under the IRB interface.
