Refer to the exhibit. Which XML tag completes this NETCONF telemetry subscription with a Cisco IOS XE device? <rpc message-id="101" xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">…
The correct answer is D. period. For NETCONF YANG-push telemetry subscriptions, the <yp:period> XML tag specifies the interval, in milliseconds, at which the device should send data updates.

Why each option
For NETCONF YANG-push telemetry subscriptions, the `<yp:period>` XML tag specifies the interval, in milliseconds, at which the device should send data updates.
`crontab` is related to scheduling tasks in Unix-like systems and is not a standard YANG-push telemetry tag.
`cadence` is a general term for rhythm or sequence but is not a specific XML tag used in YANG-push telemetry.
`frequency` is a general term, but the specific YANG-push tag for defining the interval for periodic updates is `period`.
In YANG-push subscriptions, the `<yp:period>` tag from the `ietf-yang-push` namespace is used to specify the desired data delivery interval, typically in centiseconds (10ms units) or milliseconds, which the value `1000` commonly represents.
