Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.

Network > Interfaces
Why it's wrong here
Interfaces handle packet forwarding, not specific service routing for the management/control plane.

Why it's wrong here
Virtual routers handle routing for data plane traffic, not internal firewall services.

Device > Setup > Service Route Configuration
Why this is correct

Why it's wrong here
This configures the DNS server address, but not the egress interface.
