Correct answer: dev = Device(host='192.0.2.1') dev.open() config = dev.rpc.get_config(options={'format':'json'}) print(config)

The `Device` class is the primary entry point in PyEZ. After instantiating and opening the connection with `dev.open()`, the `rpc.get_config()` method is used to retrieve configuration. Passing `options={'format':'json'}` (or specific arguments depending on the PyEZ version wrapper) instructs the device to return JSON output. The other options either use incorrect method names like `pull_config` or incorrect format arguments.

Correct answer: set class-of-service schedulers voip-sched priority strict-high

On Juniper platforms, 'strict-high' priority is designed exactly for this use case. It ensures the queue is serviced before any other queue, including 'strict-high' queues if they exist (though typically only one is recommended per port to avoid conflict), but importantly, Juniper architecture implicitly protects network control traffic in specific reserved queues or allows you to map control traffic to high priority queues. 'strict-high' is the correct setting for delay-sensitive VoIP.

Correct answers: Verify that the Router ID is manually configured on both routers.; Ensure that the link-local IPv6 addresses are reachable between the neighbors.

In OSPFv3, the Router ID is a 32-bit number. If no IPv4 address is configured on an interface (which might be the case in a pure IPv6 environment, though here we are doing IPv4 over OSPFv3), or if the system cannot automatically select one, the process fails. Manually setting the router-id is critical.

OSPFv3 uses IPv6 link-local addresses for neighbor discovery and hello packet exchange, even when transporting IPv4 routes (in a dual-stack or AF-aware configuration). If the IPv6 link-local communication is broken, the adjacency cannot form.

Correct answer: Type 2

EVPN Type 2 routes are 'MAC/IP Advertisement' routes. They carry the MAC address and optionally the IP address of hosts. This allows VTEPs to learn reachable hosts via BGP rather than data plane flooding, enabling ARP suppression and efficient forwarding.

Correct answer: Originator ID

The Originator ID is a BGP attribute (non-transitive) created by a Route Reflector. It carries the Router ID of the originator of the route in the local AS. If a router receives an update with its own Router ID in the Originator ID field, it discards the update to prevent a loop.

Correct answer: False

This is False. In a 'pre-provisioned' configuration, you explicitly map the chassis serial number to a Member ID in the configuration file. Boot order does not dictate the ID; the configuration does. The automatic election based on boot order applies to a non-provisioned (default) setup.
