The IP prefix list configuration:

ip ip-prefix TEST permit 10.0.0.0 24 less-equal 30

10.0.0.0/24: Matches because it falls within the10.0.0.0/24prefix with thesame prefix length (24).

10.0.1.0/24: Matches because it also falls within the/24network range.

10.0.2.0/24: Matches for the same reason as the above.

10.0.0.1/30: Matches because it falls within the/24 prefixand itssubnet length (30)is within theless-equal 30range.

The prefix list permits any route that falls within the10.0.0.0/24network with asubnet mask ranging from /24 to /30. Therefore,all given routes are matched.

Comprehensive and Detailed In-Depth Explanation:

Thefree mobility functionin iMaster NCE-Campus allows users to maintain consistent security policies regardless of their physical location within the campus network. To correctly implement this function, the administrator must:

A. Define security groups:Group users and devices based on roles or functions.

B. Deliver the inter-group policy:Apply policies that define how different security groups interact.

C. Deploy a policy control matrix:Establish a matrix that specifies theaccess control policiesbetween security groups.

D. Select the policy enforcement point:Choose devices or interfaces where policies are enforced, such as switches or routers.

All four steps are crucial for achieving dynamic policy enforcement in a virtualized and mobility-oriented campus network.

Huawei’sOPS (Open Programmability System)enables programmable interactions with devices through Python-based templates. In Huawei's OPS Python environment:

The classOPSConnectionis used to manage device interactions.

It includes methods like:

get()

post(self, uri, req_data)→ used tocreate resources

put(),delete(), etc.

This aligns with RESTful API semantics, and the post() method in the context given is used correctly.

Correct answer: A. TRUE
