JNCIE-SP: Juniper Networks Certified Expert – Service Provider (2021) — Question 16

When considering data center security, which component is often seen as unimportant but is really the first line of defense?

Answer options

• A. guest access
• B. native VLAN configuration
• C. RBAC
• D. physical security

Correct answer: A

Explanation

Guest access is crucial as it governs who can enter the data center, making it the first line of defense against unauthorized access. The other options, while important, focus on internal controls and configurations that do not address the initial point of entry security as effectively as managing guest access does.
