What is the purpose of the 'hello-interval' parameter on an IS-IS interface?

It specifies the number of Hello PDUs sent before an adjacency is established.

It specifies how often Hello PDUs are sent.

It specifies the maximum size of Hello PDUs.

It specifies how long to wait before declaring a neighbor down.

A network administrator is troubleshooting an IS-IS adjacency that is not forming. The `show isis interface` command shows the interface is up, and the `show isis adjacency` command shows no neighbors. The administrator checks the `show log` and sees that the router is not sending Hello PDUs. What is the most likely cause?

The `passive` statement is configured on the interface.

The `hello-interval` is set to 0.

What is the effect of configuring an IS-IS interface as passive?

The interface only sends Hello PDUs but does not receive them.

The interface is removed from the IS-IS routing process.

The interface stops sending and receiving Hello PDUs.

The interface is automatically assigned a higher metric.

What is the primary purpose of Hello PDUs in IS-IS?

To exchange link-state information

To establish and maintain adjacencies

To request a full route table from a neighbor

To authenticate routing updates

A network administrator is configuring IS-IS on a router with multiple interfaces. The administrator wants to ensure that the router can form adjacencies with both Level 1 and Level 2 neighbors on a specific interface. What is the default circuit type for an IS-IS interface in Junos OS?

The circuit type is determined by the neighbor's configuration.
