1. e-BGP is used as the routing protocol in the data center underlay.
When configuring the EVPN MP-BGP route reflector sessions, which of the following statements is FALSE?
A) A second route reflector can be deployed for redundancy purposes.
B) The cluster-id that uniquely identifies the route reflector is only configured on the route reflector itself.
C) If redundant route reflectors are deployed, the client leaf routers will receive duplicated updates.
D) The leaf's underlay autonomous system number is used for the route reflector EVPN peering sessions.
2. Consider the exhibit.
Which of the following statements about the operation of all-active multi-homing is FALSE?
A) The Ethernet segment on Leaf1 and Leaf2 is associated to lag 1.
B) The host can forward BUM traffic to either Leaf1 or Leaf2.
C) Leaf3 can load balance traffic between Leaf1 and Leaf2 when ECMP is enabled on the MAC-VRF.
D) Both Leaf1 and Leaf2 can forward BUM traffic to the host.
3. When configuring the EVPN MP-BGP route reflector sessions between the leaf and spine routers, which of the following statements is TRUE?
A) When redundant route reflectors are deployed, one route reflector will be the primary while the other one will assume a backup role.
B) The local-AS number configured within the BGP group will override the AS number configured directly under the BGP protocol.
C) The cluster-id that uniquely identifies this route reflector session is configured on the route reflector and participating clients.
D) Route reflectors can be used instead of a full mesh of eBGP sessions between the leaf and spine routers.
4. Which of the following statements about utilizing asymmetric routing in an L3 EVPN network is FALSE?
A) The ingress PE performs both MAC and IP forwarding.
B) The egress PE performs MAC forwarding only.
C) EVPN route-type 5 must be supported by the PEs involved.
D) Each MAC-VRF used in the L3 EVPN network must exist on each PE.
5. Which of the following statements does NOT describe the functionality or operation of the integrated gateway-based data center interconnect solution?
A) 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.
B) The data center gateway needs to provide interworking between the VXLAN and the WAN tunneling protocol.
C) The data center gateway and the WAN PE functions are performed on a single router.
D) The border leaf router will utilize eBGP or static routes to interconnect with the gateway.
