The provided configuration snippet is from the [edit system services] hierarchy in Junos OS, which is used to configure system-level services. The rest stanza specifically enables and configures the REST API service. Within this stanza, the https { port 3443; } statement explicitly configures the device's REST API to listen for secure, encrypted connections using the HTTPS protocol on TCP port 3443. This makes statement D a direct and accurate description of the configuration shown.

A. The configuration does not include the connection-limit statement, so there is no explicit limit of two simultaneous connections defined.

B. The enable-explorer statement enables the REST API Explorer service on the device, which clients can connect to, not allowing connections from it.

C. The configuration explicitly sets the port for HTTP connections to 3000 (http { port 3000; }), not 3030.

REST API Guide. In the "Enabling the REST API" section

the documentation outlines the configuration hierarchy. It specifies that set system services rest https port is the command used to configure the port for HTTPS requests. The exhibit clearly shows port 3443; under the https stanza.

Reference: See the "Configuring the REST API" section in the official Juniper Networks REST API Guide.

Junos OS System Basics Configuration Guide. This guide details the [edit system services] hierarchy. Under the rest options

it describes the http and https stanzas and their respective port statements for configuring listening ports. It also explains the enable-explorer statement as the method to enable the web-based API explorer interface on the device.
