CND Practice Question: Enterprise Cloud Virtual And Wireless Network Protection

An enterprise is deploying a zero-trust architecture for its AWS cloud workloads. Services must communicate across VPCs without exposing traffic to the public internet or traversing VPC peerings that open full subnet access. Which feature should be implemented?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

AWS PrivateLink with Interface VPC Endpoints

AWS PrivateLink provides private connectivity between VPCs, services, and on-premises applications securely without exposing traffic to the public internet.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • AWS Client VPN with split tunneling disabled

    Why it's wrong here

    Client VPN connects remote users to the VPC, not workload-to-workload communication.

  • AWS PrivateLink with Interface VPC Endpoints

    Why this is correct

    AWS PrivateLink uses interface endpoints powered by HyperVNI to securely expose specific services across VPCs without VPC peering.

  • AWS Direct Connect Gateway with transit VIF

    Why it's wrong here

    Direct Connect connects on-premises datacenters to AWS, not intra-cloud workload communication.

  • Inter-Region VPC Peering with restrictive Network Security Groups

    Why it's wrong here

    VPC peering opens full IP routing tables between VPCs, which violates strict zero-trust least privilege isolation.
