What are three Ethernet fabric architectures? (Choose three.)
SDN
Junos Fusion
QFabric system
Virtual Chassis Fabric
Trill
Your customer asks you to design a Data Center Interconnect solution. The solution should allow each of the tenants to use 802.1q tagging without concern for possible overlap in VLAN tags.
Which two protocols would you use to meet the customer requirements? (Choose two.)
EVPN
MLDP
VXLAN
MSTP
What are two benefits of using VXLAN overlays in a data center network? (Choose two.)
It improves load balancing
It transports Layer 2 traffic over a Layer 3 network
It provides increased VLAN and MAC scalability
It provides traffic encryption
A customer has reached the limit of their IEEE Layer 2 VLAN implementation. The customer then switches to a VXLAN overlay architecture using Layer 3.
In this scenario, how many unique VXLAN segments are mathematically available?
4,194,304
8192
4096
16,777,216
An QFX10016 switch is acting as a Layer 3 VXLAN gateway. In this scenario. which action will allow you to communicate between two VLANs?
Configure L3 physical interfaces to connect the VXLANs
Configure IRB interfaces to connect the VXLANs
Configure LAG interfaces to connect the VXLANs
Configure a VPLS instance
You are deploying a spine-and-leaf IP Fabric in your data center using EBGP. In this scenario, which three statements are true? (Choose three.)
Each device should you use a different autonomous system number
Each leaf must peer to each spine
Each device should also run an IGP to advertise loopback interfaces
EBGP does not require a next-hop self-policy
Each leaf must peer to every other leaf
Which statement is true about a Data Center Interconnect over an IP network?
Layer 2 data must traverse a point-to-point link
Layer 2 data must traverse an MPLS LSP
Layer 2 data must be encapsulated
Layer 3 data must be encapsulated
Which two technologies provide Layer 2 services across data centers in two remote locations? (Choose two.)
L3VPN
VPLS
EVPN
MSDP
You must manually configure VXLAN on a QFX5100. Which protocol is required to perform this task?
DVMRP
EBGP
PIM
MSDP
Which two statements about VXLAN are true? (Choose two.)
VXLAN uses a UDP destination port 4987
VXLAN adds an additional 32 bytes worth of headers
A VTEP is virtual or physical device that maps end devices to VXLAN segments
Devices that terminate VXLAN tunnels are known as VTEPs
Spine 1 and Spine 2 are MX Series devices configured to act as redundant VXLAN Layer 3 Gateways using the virtual-gateway-address 10.0.1.254 statement
The Spine Node will send an ARP reply specifying The Mac Address of its IRB interface
The Spine Node will send an ARP reply specifying a Virtual Mac Address 0f 00:00:5e:00:01:01
The Spine Node will send an ARP reply specifying The Mac Address of its LT Interface
The Spine Node will send an ARP reply specifying The Mac Address of its leaf-facing interface
Which 3 benefits do VXLANs offer to VLANs? (Choose three.)
It provide better utilization of available paths in the overlay infrastructure
VXLAN uses a 24-bit VNID to overcome the 4094 vlan scale limitation
VXLAN uses a 16-bit VNID to overcome the 4094 vlan scale limitation
It provides better utilization of available network paths in the underlay infrastructure
It provides a solution to extent Layer 2 segments over a shared Layer 3 routed network
