C1000-138 practice question 9 of 15

Which options would be selected to manage the lifecycle of a version of a Product?

Full set: 60 questions

Answer options

A: Set endpoint

B: Set migration target Correct answer

C: Set burst limit

D: Set rate limit

Correct Answer:

B. Set migration target

Explanation

Managing the lifecycle of a Product in API Connect involves controlling its state from development to retirement. When a new version of a Product is created (e.g., v2.0), a key lifecycle management action is to migrate existing application subscriptions from the old version (e.g., v1.0) to the new one. The "Set migration target" option is specifically designed for this purpose. It designates the new Product version as the target for subscriptions of a specified older Product, facilitating a smooth upgrade path for API consumers.

Why Incorrect

A. Setting an endpoint is part of the API's implementation and assembly, not a Product lifecycle management action.
C. Setting a burst limit is a traffic control policy configured within a Product's Plan, not a direct lifecycle management function.
D. Setting a rate limit is a traffic control policy configured within a Product's Plan, not a direct lifecycle management function.

For example, if you create a new version of a Product, you can migrate the existing subscriptions to the new version... To enable the migration of subscriptions, you set a migration target on the source Product."

Question breakdown

Tests: Manage Product version lifecycle
Difficulty: Easy

Key idea: Setting a migration target on a Product version lets subscriptions move to a superseding version as the old one is deprecated or retired.

How to reach the answer

The clue is 'lifecycle of a version of a Product', which concerns moving between versions.
Lifecycle actions on a Catalog Product include publish, deprecate, retire, supersede, replace and set migration target.
Set migration target points an older version at its successor so subscribers can migrate.
Rate limit, burst limit and endpoint are Plan or API settings, not lifecycle actions, so B is correct.

Each option

AIncorrect. Endpoints are configured at the API or Catalog level, not as a Product lifecycle action.
BCorrect. Set migration target is a Product lifecycle action that links an old version to its replacement for subscription migration.
CIncorrect. Burst limits control short-term traffic within a Plan and do not manage version lifecycle.
DIncorrect. Rate limits govern call volume per Plan, not version transitions.

Common trap: Rate and burst limits are configured on Products and Plans, so they can seem like 'Product management' options even though they have nothing to do with lifecycle.

In practice: When releasing v2 of a Product, providers set v2 as the migration target on v1 and then deprecate v1. App developers can then move their subscriptions before v1 is retired.

Remember: Version lifecycle uses the deprecate/retire/supersede/replace/set-migration-target actions, not throttling settings.
