D.
If no configuration file is referenced in DHCP Options, the switch downloads a default configuration file from the storage server.
Answers
Suggested answer: A, C

Explanation:

In Zero Touch Provisioning (ZTP), the process is streamlined to simplify the deployment of new switches in the network. When a switch that supports ZTP boots and does not find a configuration file, it attempts to acquire one using DHCP. If the switch is already running the firmware image specified by the DHCP server (if mentioned), it proceeds to the next step without re-downloading the image. DHCP Option 43 suboption 01 is used by the DHCP server to provide the URL of the configuration file to the switch.

D.
Increase the physical MTU on all ports on all devices participating in VXLAN using EVPN signaling.
Answers
Suggested answer: D

Explanation:

Increasing the physical MTU on all ports of devices participating in a VXLAN EVPN signaling network is essential. VXLAN encapsulation adds additional bytes to the Ethernet frame, which can lead to packet drops if the MTU is not large enough to accommodate the increased frame size. Ensuring that the physical MTU is set correctly on all devices allows for successful transmission of VXLAN encapsulated packets.
