Which IP fabric underlay protocol provides the highest degree of scalability?

IS-IS
IS-IS
RIP
RIP
EBGP
EBGP
OSPF
OSPF
Suggested answer: C
Explanation:

Among the listed protocols, External Border Gateway Protocol (EBGP) provides the highest degree of scalability for an IP fabric underlay. EBGP is designed for inter-autonomous system routing and thus is well-suited to handle large-scale network environments with robustness and scalability. It is commonly used in data center fabrics due to its ability to efficiently manage routing information and scale with the network as it grows.

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

A logical interface can participate in multiple VRFs.
A logical interface can participate in multiple VRFs.
Multiple VRFs on a single device consolidate routing information to a single table.
Multiple VRFs on a single device consolidate routing information to a single table.
VRFs have independent routing tables.
VRFs have independent routing tables.
VRFs support overlapping subnets.
VRFs support overlapping subnets.
Suggested answer: 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.)

ES-lmport route target
ES-lmport route target
Ethernet segment
Ethernet segment
MAC mobility
MAC mobility
MAC advertisement
MAC advertisement
Suggested answer: 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.)

It can be implemented in a bridge overlay architecture.
It can be implemented in a bridge overlay architecture.
VLAN normalization is supported.
VLAN normalization is supported.
Multiple VLAN IDs per EVI are supported.
Multiple VLAN IDs per EVI are supported.
It can be implemented in an ERB architecture.
It can be implemented in an ERB architecture.
Suggested answer: 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.

A customer wants to connect two data centers on different subnets using EVPN. What are two implications of using different IP subnets at each site? (Choose two.)

Using different IP subnets at each site allows Layer 3 gateways to exchange only type-3 routes.
Using different IP subnets at each site allows Layer 3 gateways to exchange only type-3 routes.
MAC addresses will need to be advertised between the data centers.
MAC addresses will need to be advertised between the data centers.
MAC addresses will not need to be advertised between the data centers.
MAC addresses will not need to be advertised between the data centers.
Using different IP subnets at each site allows Layer 3 gateways to exchange only type-5 routes.
Using different IP subnets at each site allows Layer 3 gateways to exchange only type-5 routes.
Suggested answer: B, D
Explanation:

When connecting two data centers on different subnets using EVPN, MAC addresses need to be advertised between the data centers to maintain Layer 2 connectivity. Using different subnets implies the need for Layer 3 gateways at each site, which typically involve exchanging type-5 routes in an EVPN context.
