JNCIA-Cloud: Juniper Networks Certified Associate – Cloud (2023) — Question 1

Which two statements are true regarding isolated namespaces in Juniper Cloud-Native Contrail Networking (CN2)? (Choose two.)

Answer options

• A. Pods in isolated namespaces can only communicate with pods in the same namespace.
• B. Pods in isolated namespaces can reach services in non-isolated namespaces.
• C. Pods in isolated namespaces can only reach services in the same namespace.
• D. Pods in isolated namespaces can communicate with pods in non-isolated namespaces.

Correct answer: A, B

Explanation

The correct answers are A and B because pods in isolated namespaces are restricted to communicating solely with other pods in their namespace, but they can access services in non-isolated namespaces. Options C and D are incorrect as they misrepresent the communication capabilities of isolated namespaces, specifically that they cannot communicate with pods in non-isolated namespaces.
