Free Nokia SR Linux EVPN and Data Center Interconnect Practice Questions

A.  

The centralized router must be a member of the Ethernet segment.

B.  

All routers participating in the Ethernet segment must have the multi-homing mode set to all-active.

C.  

Remote leaf routers can load balance traffic to customer prefixes through the leaf routers connected to the Ethernet segment.

D.  

The centralized router will advertise the customer prefixes using an EVPN route-type 5 update.

A.  

Each PE participating in the Layer 2 EVPN must be configured with the same EVPN instance ID (EVI).

B.  

The route distinguisher is auto-generated using the autonomous system number and EVI.

C.  

Only one VXLAN-interface can be associated to the Layer 2 EVPN.

D.  

The route-targets are manually configured when the leaf routers are in different autonomous systems.

A.  

Leaf-1 and Leaf-2 will advertise the IP prefixes to each other using EVPN route-type 5.

B.  

Leaf-1 and Leaf-2 must both have instances of MAC-VRF1 and MAC-VRF2.

C.  

Leaf-1 and Leaf-2 will advertise host MAC/IP address information using EVPN route-type 2.

D.  

MAC-VRF1 and MAC-VRF2 will connect to IP-VRF3 using an IRB interface.

A.  

An IRB interface is used to logically interconnect a MAC-VRF to an IP-VRF on a P

E.  

B.  

IP-VRFs and MAC-VRFs can have multiple IRB interfaces.

C.  

The IRB sub-interface must have at least one IP address.

D.  

The IRB sub-interfaces can be configured with access control lists.

A.  

The IP addresses of the leaf routers need to be re-distributed into the WAN.

B.  

The EVPN overlay is transparently carried over the WAN network.

C.  

The leaf routers are able to establish a full mesh of VXLAN tunnels across the WAN.

D.  

The data center gateway routers maintain a MP-BGP EVPN peering with the data center route reflector.

A.  

The data center gateway and the WAN PE functions are performed on a single router.

B.  

The border leaf router will utilize eBGP or static routes to interconnect with the gateway.

C.  

The data center gateway needs to provide interworking between the VXLAN and the WAN tunneling protocol.

D.  

The data center gateway needs to be able to re-advertise Layer 3 EVPN routes of the leaf routers into VPN-IPv4 or VPN-IPv6 routes if required.
