You are deploying a switch using ZTP.
Which two statements are true in this scenario? (Choose two.)

  1. If the switch is already running the referenced image, no action is performed and the switch moves to the next ZTP step in the ZTP process.
  2. Using DHCP Option 150. the DHCP server informs the switch of a software image name.
  3. Using DHCP Option 43 sub option 01, the DHCP server informs the switch of the configuration file name.
  4. If no configuration file is referenced in DHCP Options, the switch downloads a default configuration file from the storage server.

Answer(s): 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.

You are asked to build a single export policy that can be applied to all devices to advertise only loopback IP addresses in the 172.16.0.0/24 subnet into your EBGP IP fabric. In this scenario, which two solutions would accomplish this task? (Choose two.)



  1. Option A
  2. Option B
  3. Option C
  4. Option D

Answer(s): B



When considering VRF routing-instances for network segmentation, which two statements are true? (Choose two.)

  1. A logical interface can participate in multiple VRFs.
  2. Multiple VRFs on a single device consolidate routing information to a single table.
  3. VRFs have independent routing tables.
  4. VRFs support overlapping subnets.

Answer(s): C,D

Explanation:

Virtual Routing and Forwarding (VRF) instances allow multiple virtual routing tables to exist on a single physical router. Each VRF has its own independent routing table, which allows network paths to be segmented without interference from other VRFs. This design supports overlapping IP address spaces, enabling the same IP subnet to be used in different VRFs without conflict.

What are two types of EVPN routes? (Choose two.)

  1. ES-lmport route target
  2. Ethernet segment
  3. MAC mobility
  4. MAC advertisement

Answer(s): C,D

Explanation:

In Ethernet VPN (EVPN), MAC mobility and MAC advertisement are crucial route types. MAC mobility is used to handle the movement of MAC addresses between different network locations, ensuring accurate and efficient traffic forwarding. MAC advertisement routes are used to advertise the presence of MAC addresses, enabling the correct forwarding of Ethernet frames in an EVPN environment.

You are considering deploying a MAC-VRF type routing instance with a VLAN-bundle service type. In this scenario, which two statements are correct? (Choose two.)

  1. It can be implemented in a bridge overlay architecture.
  2. VLAN normalization is supported.
  3. Multiple VLAN IDs per EVI are supported.
  4. It can be implemented in an ERB architecture.

Answer(s): A,C

Explanation:

A MAC-VRF (MAC Virtual Routing and Forwarding) instance with a VLAN-bundle service type is used in EVPN-VXLAN architectures. It can be implemented in a bridged overlay architecture where Ethernet segments are bridged across the EVPN-VXLAN network. This setup supports multiple VLAN IDs per Ethernet VPN Instance (EVI), enabling the segregation and transport of traffic from different VLANs over the same EVPN-VXLAN infrastructure.
