Juniper JN0-683 Exam - Topic 4 Question 7 Discussion

Actual exam question for Juniper's JN0-683 exam

Question #: 7
Topic #: 4

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?

AUse route leaking with EVPN and a routing policy.

BUse filter-based forwarding.

CPut the new server on a unique subnet within the tenant's network.

DUse a static route in the tenant VRF with a firewall as the next hop for traffic to the new server.

Show Suggested Answer

Suggested Answer: B, C, E

Understanding ERB Architecture:

ERB (Edge Routed Bridging) architecture is a network design where the routing occurs at the edge (leaf devices) rather than in the spine devices. In a VXLAN overlay network with EVPN as the control plane, leaf devices typically act as both Layer 2 (L2) and Layer 3 (L3) VXLAN gateways.

Placement of VXLAN Gateways:

Option B: All leaf devices will have L2 VXLAN gateways to handle the bridging of VLAN traffic into VXLAN tunnels.

Option C: All leaf devices will also have L3 VXLAN gateways to route traffic between different VXLAN segments (VNIs) and external networks.

Option E: Spine devices in an ERB architecture generally do not function as VXLAN gateways. They primarily focus on forwarding traffic between leaf nodes and do not handle VXLAN encapsulation/decapsulation.

Conclusion:

Option B: Correct---All leaf devices will have L2 VXLAN gateways.

Option C: Correct---All leaf devices will have L3 VXLAN gateways.

Option E: Correct---Spine devices will not act as VXLAN gateways

I feel like using a static route with a firewall as the next hop could be overkill for this scenario, but it might be worth considering.

Putting the server on a unique subnet seems like a straightforward approach, but I'm not convinced it fully limits access as required.

I remember practicing with filter-based forwarding, so option B might be the right choice, but I need to double-check the specifics.

This is a tricky one, but I'm feeling confident. I'm leaning towards option B, filter-based forwarding, as it seems to directly address the requirement of limiting access without a firewall.

Based on the details provided, I think option A with EVPN and a routing policy could be a good solution. It seems like it would allow me to control the traffic without a full firewall.

I'm a bit confused by the wording of the question. Does "route leaking" mean something specific in this context? I'll need to review that concept before deciding.

Okay, let's see. The key here is limiting access to a specific traffic type without going through a firewall. I think option B, using filter-based forwarding, might be the way to go.

Hmm, I'm a bit confused by the wording of the question. Does the fact that Unit A has those extra profile options mean that all transactions get automatically assigned there, or is it just that Paul can only create them for that unit? I'll have to re-read it carefully.

Hmm, I wonder if we can use a magic spell to teleport the new server into a secure bubble. Might be faster than these networking options!
