JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing (legacy) — Question 8

You have configured source NAT with port address translation. You also need to guarantee that the same IP address is assigned from the source NAT pool to a specific host for multiple concurrent sessions.
Which NAT parameter would meet this requirement?

Answer options

• A. port block-allocation
• B. port range twin-port
• C. address-persistent
• D. address-pooling paired

Correct answer: D

Explanation

The correct answer is D, 'address-pooling paired,' as it ensures that a specific host consistently receives the same IP address for multiple sessions. The other options do not guarantee the same IP assignment across concurrent sessions, making them unsuitable for this requirement.
