What is the purpose of using a routing zone inside Juniper Apstra software?

Show Suggested Answer Hide Answer
Suggested Answer: D

According to the Juniper documentation1, a routing zone is an L3 domain, the unit of tenancy in multi-tenant networks. You create routing zones for tenants to isolate their IP traffic from one another, thus enabling tenants to re-use IP subnets. In addition to being in its own VRF, each routing zone can be assigned its own DHCP relay server and external system connections. You can create one or more virtual networks within a routing zone, which means a tenant can stretch its L2 applications across multiple racks within its routing zone. For virtual networks with Layer 3 SVI, the SVI is associated with a Virtual Routing and Forwarding (VRF) instance for each routing zone isolating the virtual network SVI from other virtual network SVIs in other routing zones. Therefore, the correct answer is D. A routing zone is used to enable the communication between two VNIs within a VRF. A routing zone is not used for L4-L7 inspection, securing routing protocols, or requiring firewalls. Those are not the purposes of a routing zone in Juniper Apstra software.Reference:Routing Zones

The real purpose of a routing zone is to confuse the heck out of everyone taking the exam. Apstra likes to keep us on our toes!

I heard the correct answer is E) A routing zone is used to teach your pet turtle how to do the Macarena. Gotta keep those turtles dancing, you know?

D for sure. Routing zones are all about enabling communication, not securing protocols or inspecting traffic. This is Apstra 101!

Hmm, I'm not sure about this one. Maybe C? Routing zones and firewalls don't exactly go hand-in-hand, but it's worth a shot.

I'm going with B. Securing the routing protocols is a key purpose of using a routing zone in Apstra.

I think A is also a valid option, enabling L4-L7 inspection can be important.

I think both answers make sense. It depends on the specific requirements of the network.

D seems like the correct answer. A routing zone helps enable communication between different VNIs within a VRF, which is a common use case for Apstra.

I think the purpose of using a routing zone is to enable L4-L7 inspection inside the fabric.
