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.

NEW QUESTION 30
Which of the following statements about MAC mobility is TRUE?

The original PE advertises the locally learned MAC with the sequence number set to a maximum value.

A PE advertising a local MAC that was previously learned through EVPN, will decrement the sequence number in its update.

The originating PE generates a withdraw message after the same locally learned MAC has aged out.

The originating PE and the destination PE must synchronize their MAC tables.

NEW QUESTION 31
Consider the exhibit.

Which of the following statements about the operation of all-active multi-homing is FALSE?

Both Leaf1 and Leaf2 can forward BUM traffic to the host.

Leaf3 can load balance traffic between Leaf1 and Leaf2 when ECMP is enabled on the MAC-VRF.

The Ethernet segment on Leaf1 and Leaf2 is associated to lag 1.

The host can forward BUM traffic to either Leaf1 or Leaf2.

NEW QUESTION 32
Which of the following statements about the gateway-less data center interconnect solution is FALSE?

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

The EVPN overlay is transparently carried over the WAN network.

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

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

NEW QUESTION 33
Which of the following statements about the decoupled gateway-based data center interconnect solution is FALSE?

VLAN tags are used to identify traffic between the data center border leaf and the WAN PE.

The EVPN services in the data center are interconnected to different VPN services in the WAN.

The separation between the border leaf and the WAN PE provides a clear demarcation for security and QoS.

The WAN PE maintains a peering session with the data center route-reflector for the exchange of updates.

NEW QUESTION 34
Consider the exhibit.

Leaf1 and Leaf2 have the Ethernet segment configured to use the default election algorithm while Leaf3 and Leaf4 are configured to use the preference-based algorithm with Leaf3 having the higher preference value. The DF candidate list is the same on all leaf routers.
Which of the following leafs is the DF for mac-vrf103?

Leaf1

Leaf2

Leaf3

Leaf4

NEW QUESTION 35
Which of the following statements does NOT describe the functionality or operation of the integrated gateway-based data center interconnect solution?

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

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

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

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.

NEW QUESTION 36

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

Identifies the redundancy mode of the Ethernet segment.

NEW QUESTION 39
Which of the following statements about PE-CE routing is FALSE?

There are two methods to implement routing between the PE and CE, static and dynamic.

BGP is the preferred option for PE-CE routing as it scales better than static routing.

eBGP is preferred which means that the PE and CE are required to be in different autonomous systems.

The CE advertises BGP EVPN route type 5 updates to the PE and the PE forwards to other PEs.

NEW QUESTION 40
Which of the following EVPN route-types is used to implement aliasing?

Ethernet segment routes

AD per ES routes

AD per EVI routes
