In Advanced Policy-Based Routing (APBR), how are routing instances used to direct traffic?

APBR uses routing instances to isolate the management plane from the data plane

APBR uses routing instances only for load balancing, not for policy-based routing

APBR creates a new routing instance for each application automatically

APBR selects a routing instance based on application and policy, and then routes traffic using that instance's routing table

A network architect is designing a multi-tenant environment on a single MX router. Each tenant requires its own routing table, but they also need to exchange routes with each other through a controlled policy. Which routing instance type and configuration approach should be used?

Use VRF instances and configure vrf-import/vrf-export policies to control route exchange.

Use virtual-router instances and configure route leaking between them.

Use a single routing instance and rely on firewall filters to isolate tenants.

Use virtual-switch instances and configure IRB interfaces for routing.

A data center operator needs to separate Layer 2 broadcast domains for two tenants while also providing each tenant with its own Layer 3 routing table for inter-VLAN routing. Which routing instance type should be used to achieve both Layer 2 and Layer 3 isolation?

A company uses APBR to steer Office 365 traffic to a dedicated link. They have multiple VRFs for different business units. The APBR policy should apply to all VRFs, but with different next-hop links for each VRF. What is the most efficient way to configure this?

Use firewall filters in each VRF to steer Office 365 traffic.

Create a single APBR policy and apply it to all VRFs, using a routing table to select the next-hop.

Create a single APBR policy and apply it to the default routing instance, relying on VRF route leaking.

Create a separate APBR policy for each VRF, each with the appropriate next-hop.

Part of the Advanced Policy-Based Routing (APBR) domain, which makes up ~10% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~4–6 in this domain), expect 1–2 from this objective — we provide 16 practice questions to prepare you well beyond it.

A service provider wants to offer separate Internet access to two business customers using a single MX series router. Each customer must have its own routing table and cannot see the other's routes. The provider also plans to use APBR to steer traffic from each customer based on application signatures. Which routing instance type should be configured for each customer?
