How is the default IS-IS metric assigned to an interface on a Juniper device?

It is derived from the interface bandwidth.

It is manually assigned per interface and has no default.

It is set to 10 automatically when IS-IS is enabled on the interface.

It is calculated based on the interface's MTU.

An IS-IS network has two paths to a destination. Path A is internal to the IS-IS domain, and Path B is external, redistributed from another routing protocol. Both paths have the same metric. Which path will be preferred by the SPF algorithm?

The path with the lower interface metric is preferred, regardless of internal or external.

Path B, because external routes are always preferred over internal routes.

Path A, because internal routes are always preferred over external routes.

Both paths are equally preferred, and load balancing is performed.

Part of the IS-IS domain, which makes up ~15% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~5–9 in this domain), expect 1–1 from this objective — we provide 16 practice questions to prepare you well beyond it.

A router in an IS-IS network has three interfaces with the following metrics: ge-0/0/0 has a metric of 10, ge-0/0/1 has a metric of 20, and ge-0/0/2 has a metric of 30. The router receives an LSP from a neighbor that advertises a route with a metric of 40. What is the total metric for this route?
