   A company has a policy that all core routers must have a specific BGP export policy applied. An engineer writes a JSNAPy test to verify this. The test file uses `assert` with `contains` to check for the policy name in the BGP configuration. The test passes, but the engineer later discovers that the policy is not actually applied to any BGP group. Why did the test pass?

   • AThe `contains` test is case-insensitive and matched a different policy.
   • BThe snapshot was taken before the policy was removed.
   • CThe `contains` test checks the entire configuration, not just the BGP section.
   • DThe `contains` test only checks the first BGP group.

   An organization has a mix of Junos devices that use different authentication methods: some use username/password, and others use SSH keys. The engineer wants to use a single JSNAPy configuration file to manage all devices. How can this be achieved?

   • ACreate separate configuration files for each authentication method and run JSNAPy separately for each group.
   • BUse the `defaults` section in the configuration file to set common parameters and override per-device in the `devices` section.
   • CConfigure all devices to use the same authentication method.
   • DUse environment variables in the configuration file to specify credentials per device.
