A YAML file uses an anchor to define a common set of BGP parameters. The engineer writes: bgp_defaults: &bgp_defaults local-as: 65000 peer-as: 65001 router1: <<: *bgp_defaults local-as: 65010 router2: <<: *bgp_defaults What is the value of 'local-as' for 'router2'?

An error occurs because the anchor is modified by 'router1'.

A network engineer is writing a YAML file to define common SNMP settings for multiple devices. To avoid repetition, the engineer wants to define a default set of parameters and then reference it for each device. Which YAML feature should be used?

YAML multi-document markers (---)

A DevOps engineer is creating a YAML configuration file for a CI/CD pipeline. The file needs to define a list of build steps, where each step has a name and a command. The engineer writes the following: steps: - name: compile command: make - name: test command: make test Which statement accurately describes this YAML structure?

It is an invalid YAML structure because sequences cannot contain mappings.

It is a sequence of mappings, where each mapping has two key-value pairs.

It is a mapping of two sequences, each containing a mapping.

It is a mapping with a nested mapping, and the sequence is implicit.

A DevOps engineer is maintaining a YAML file that contains configuration for both a staging and a production environment. The engineer wants to keep both configurations in the same file but ensure that a parser reading the file only processes one environment at a time. What is the correct approach?

Use a folded block scalar to encapsulate each environment.

Use YAML anchors to define both environments and reference them separately.

Use the '---' document separator to split the file into two YAML documents.

Use comments to disable the environment that is not needed.

Part of the Data Serialization domain, which makes up ~9% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~3–5 in this domain), expect 2–3 from this objective — we provide 26 practice questions to prepare you well beyond it.

An engineer is writing a YAML file to store a description for a network interface. The description spans multiple lines and should be displayed as a single line when applied to the device (i.e., line breaks should be converted to spaces). Which block scalar style should be used?
