QUESTION 24
Consider the exhibit.

All three of the leafs have a MP-BGP EVPN session to the route-reflector Spine-1. Leaf-1, Leaf-2 and Leaf-3 have existing instances of an L2 EVPN named MAC VRF-1. Host-1 has just sent its first Ethernet frame into MAC VRF-1 on Leaf-1.
Which of the following steps is FALSE?

Leaf-1 populates Host-1’s MAC address learnt on the local interface to its MAC table.

Leaf-1 generates an EVPN route-type 5 update with Host-1’s MAC address and sends it to the route reflector.

The route-reflector forwards the EVPN update to Leaf-2 and Leaf-3.

Leaf-2 and Leaf-3 import the EVPN update based upon the route target.

QUESTION 25
Which of the following statements about the gateway-less data center interconnect solution is FALSE?

It provides a clear demarcation for security between the border leaf and gateway.

All of the data centers leaf routers must be reachable over the WAN network.

The route reflectors must be reachable between different data centers.

The data center border leaf and gateway can use either eBGP or static routes to exchange routing information.

QUESTION 26
Which of the following statements about the configuration of a distributed Layer 2 EVPN in a Nokia SR Linux is FALSE?

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

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

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

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

QUESTION 27
A host is connected to multiple PEs through multi-homing.
Which of the following is NOT a function of the EVPN route-type 4 route?

Allows the other PEs to discover which PEs are connected to the same Ethernet segment.

Triggers the election of a designated forwarder.

Identifies the type of algorithm to be used in the election process.

Identifies the redundancy mode of the Ethernet segment.

QUESTION 28
Which of the following statements about a distributed Layer 2 EVPN is FALSE?

When a host connected to a Layer 2 EVPN responds to an ARP request, it sends an ARP reply to the local leaf.

The local leaf replicates the ARP reply and sends it to all the leafs in the flooding list for that Layer 2 EVPN.

The local leaf learns the source MAC address from the Ethernet frame and populates it into its MAC forwarding table.

The local leaf generates an EVPN route type 2 and sends it to all of its configured BGP EVPN neighbors.

QUESTION 29
Which of the following statements about a BGP route target is FALSE?

The route-target is a BGP extended community.

It is defined in MP-BGP to allow for overlapping MAC addresses from multiple tenants.

It is advertised with every EVPN route update.

It identifies the EVPN instance in the control plane.

QUESTION 30
Which of the following EVPN route-types is used to implement aliasing?

Ethernet segment routes

AD per ES routes

AD per EVI routes

IP/MAC routes

QUESTION 31
When providing L3 multi-homing on two or more leaf routers, which of the following is FALSE?

In a single-active multi-homing scenario, the DF-election is used to identify the active leaf router.

In an all-active multi-homing scenario, the DF-election is used to identify the leaf router that is responsible for forwarding BUM traffic to the host.

All learned 3rd party prefixes are advertised using EVPN route type 5.

The Ethernet segment is associated with the next-hop for the 3rd party prefixes.

QUESTION 32
A host is connected to multiple PEs through multi-homing.
Which of the following is NOT a function of the EVPN route-type 4 route?

Allows the other PEs to discover which PEs are connected to the same Ethernet segment.

Identifies the redundancy mode of the Ethernet segment.

Identifies the type of algorithm to be used in the election process.

Triggers the election of a designated forwarder.

QUESTION 33
Which of the following statements about the Layer 2 EVPN configuration/operation in a Nokia SR Linux is FALSE?

The Layer 2 EVPN is implemented as a MAC-VRF.

MAC-VRF is configured with a VXLAN-interface towards each remote VTEP.

Data plane MAC learning takes place on the local interfaces.

Remote MAC addresses are learned from MP-BGP EVPN updates.

QUESTION 34
Consider the exhibit.

dcgw10 is a Nokia 7750SR and is used as the integrated gateway.
Which of the following is NOT configured in VPLS 100 on dcgw10?

The EVI to be used by the VPLS.

A VXLAN instance with the VNI for the VPLS.

A BGP instance with two unique route targets.

The BGP instance bound to the MPLS tunnels toward dcgw20.

QUESTION 35
Which of the following statements about configuring and using an integrated routing and bridging (IRB) interface is TRUE?

The IRB sub-interface must be configured as either type bridge or routed.

A MAC-VRF can be configured with multiple IRB sub-interfaces to support multi-homing.

When the IRB sub-interface is configured with multiple IP addresses, one of them can be configured as the primary.

When using an IRB interface to interconnect a MAC-VRF to an IP-VRF, one sub-interface is configured for the MAC-VRF and another one for the IP-VRF.

QUESTION 36
Consider the exhibit.

Host-2 is sending data to Host-1. The network is designed to use asymmetric routing.
Which of the following statements about the operation of the data plane is TRUE?

Leaf-1 forwards the data for mac-vrf-2 towards Leaf-2 with a VNI of 2.

Leaf-2 forwards the data for mac-vrf-2 towards the IP-VRF using its IRB interface.

Leaf-2 IP-VRF consults the ARP table to learn Host-1 MAC address.

Leaf-2 does a MAC look-up using mac-vrf-1 and forwards the data towards Host-1.

QUESTION 37
Leaf routers are configured to support Layer 2 multi-homing all-active mode.
Which of the following statements is FALSE?

A LAG must be configured on the participating leaf routers.

If VLAN tagging is to be used, then it must be enabled on the LAG interface.

If using LACP, the system-id-mac must uniquely identify each leaf router connected to the host.

The LAG interface must then be associated with the Ethernet segment.

QUESTION 38
Consider the exhibit.

Which of the following statements is FALSE?

The remote host’s IP address is 100.0.2.3.

The MAC address 00:00:00:00:00:01 was learned through the data plane.

The MAC address associated to the vxlan-interface will not age out.

The VXLAN network identifier configured for this MAC-VRF is 100.

QUESTION 39
Consider the exhibit.

Which of the following statements about the proxy ARP entry for the neighbor IP 192.168.100.1 is FALSE?

The state is pending because this MAC address was originally associated with a different IP address.

The traffic will be forwarded to a blackhole if the state changes to duplicate.

The MAC address will be changed to 00:00:00:00:DE:AD if the state changes to duplicate.

All traffic destined to 192.168.100.1 will be discarded for 9 minutes if the state changes to duplicate.

QUESTION 40
When configuring the EVPN MP-BGP route reflector sessions between the leaf and spine routers, which of the following statements is TRUE?

The local-AS number configured within the BGP group will override the AS number configured directly under the BGP protocol.

The cluster-id that uniquely identifies this route reflector session is configured on the route reflector and participating clients.

When redundant route reflectors are deployed, one route reflector will be the primary while the other one will assume a backup role.

Route reflectors can be used instead of a full mesh of eBGP sessions between the leaf and spine routers.

QUESTION 41
Consider the exhibit.

Which of the following statements about the configuration and operation of this setup is FALSE?

A sub-interface of lag1 is associated to the MAC-VRF on Leaf1 and Leaf2.

The Ethernet segment ES-1 is configured with multi-homing-mode all-active.

The MAC-VRF on Leaf3 will need to be configured with ECMP to be able to load balance between Leaf1 and Leaf2.

The host will forward all BUM traffic toward the DF.
