Free Data Center Professional Exam JN0-683 Exam Practice Test

You are deploying a new network lo support your Al workloads on devices that support at least 400 Gbps Ethernet. There is no requirement for any Layer 2 VLANs in this network. Which network architecture would satisfy this requirement?

• an IP fabric using PIM-SM to signal VXLAN overlay
• an IP fabric using the EVPN-MPLS architecture
• an IP fabric with an EVPN-VXLAN architecture
• an IP fabric using EBGP

You are selling up an EVPN-VXLAN architecture (or your new data center. this initial deployment will be less than 50 switches: however, it could scale up to 250 switches over time supporting 1024 VLANs. You are still deciding whether to use symmetric or asymmetric routing.In this scenario, which two statements are correct? (Choose two.)

• Symmetric routing needs an extra VLAN with an IRB interface for each L3 VRF instance.
• Asymmetric routing is easier lo monitor because of the transit VNI.
• Symmetric routing supports higher scaling numbers.
• Asymmetric routing routes traffic on the egress switch.

You are adding a server lo a tenant's network within your data center and must limit access to a specific traffic type within the tenant network without pushing all tenant traffic through a firewall. What will satisfy this requirement?

• Use route leaking with EVPN and a routing policy.
• Use filter-based forwarding.
• Put the new server on a unique subnet within the tenant's network.
• Use a static route in the tenant VRF with a firewall as the next hop for traffic to the new server.

You are implementing VXLAN broadcast domains in your data center environment. Which two statements are correct in this scenario? (Choose two.)

• A VXLAN packet does not contain a VLAN ID.
• The VNI must match the VLAN tag to ensure that the remote VTEP can decapsulate VXLAN packets.
• Layer 2 frames are encapsulated by the source VTEP.
• The VNI is a 16-bit value and can range from 0 through 16.777.215.

You are preparing an sFlow monitoring system configuration.In this scenario, what Information will be included in the datagram sent to the sFlow collector? (Choose two.)

• the interlace through which the packets entered the agent
• the sending device's serial number
• the CRC from the sampled packet
• the source and destination VLAN for sampled packets

Which two statements are true about EVPN routes for Data Center Interconnect? (Choose two.)

• Type 5 EVPN routes require a VXLAN tunnel to the protocol next hop.
• Type 2 EVPN routes do not require a VXLAN tunnel to the protocol next hop.
• Type 2 EVPN routes require a VXLAN tunnel to the protocol next hop.
• Type 5 EVPN routes do not require a VXLAN tunnel to the protocol next hop.

Which two statements are correct about an IP fabric? (Choose two.)

• All leaf devices can use the same AS number in an IP fabric without making any adjustments to the EBGP configuration
• The multipath multiple-as statement is required to enable ECMP if every device has a different AS number.
• Only a single point to point EBGP session is required between peers in an IP fabric.
• FBGP is only required to route most routing information to external devices outside the fabric.

You want to ensure that VXLAN traffic from the xe-0/0/12 interlace is being encapsulated by logical vlep.32770 and sent to a remote leaf device in this scenario, which command would you use to verify that traffic is flowing?

• monitor traffic interface xe-0/0/12
• show interface terse vtep.32770
• show interfaces terse vtep.32770 statistics
• show interfaces vtep.32770 detail

You are asked to implement VXLAN group-based policies (GBPs) in your data center. Which two statements are correct in (his scenario? (Choose two.)

• VXLAN GBP uses scalable group tags that must be configured statically on each switch and activated through 802.1X.
• VXLAN GBP uses scalable group tags that may be configured on a RADIUS server and pushed to the switch through 802.1X.
• VXLAN GBP ensures consistent application of security group policies throughout the network.
• VXLAN GBP ensures consistent application of BGP groups throughout the network.

Which three statements are correct about symmetric IRB routing with EVPN Type 2 routes? (Choose three.)

• An L3 interface (IRB) is required for each local VLAN.
• Symmetric routing requires MAC-VRF.
• Symmetric routing supports the EVPN service VLAN bundle.
• Symmetric routing requires an extra transit VNI for each VRF.
• Symmetric routing is less efficient than asymmetric routing.
