JNCIA-Cloud: Juniper Networks Certified Associate – Cloud — Question 39

What are two characteristics of an overlay network in a cloud networking data center? (Choose two)

Answer options

• A. An overlay network provides physical connectivity between hosts
• B. An overlay network uses Layer 2 tunneling technologies to interconnect hosts
• C. An overlay network must reside in virtual machines within the data center
• D. An overlay network provides logical connectivity between tenant networks

Correct answer: B, D

Explanation

The correct answers are B and D because an overlay network indeed utilizes Layer 2 tunneling technologies to facilitate connections among hosts and provides logical connectivity between tenant networks. Options A and C are incorrect since an overlay network does not provide physical connectivity, and it is not a requirement for such networks to exist solely within virtual machines.
