3CX ACADEMY ADVANCED
CERTIFICATION PRACTICE
EXAM Question 1: A company wants full control of its 3CX host OS and networking and is prepared to manage the underlying server itself. Which deployment model best matches this requirement?
Choices:
1) 3CX Hosted only 2) On-premise or self-hosted 3CX 3) 3CX SMB FREE only 4) A bridge-only deployment
Correct Answer: On-premise or self-hosted 3CX
Explanation: On-premise and self-hosted deployments give the organization control of the server and network environment. They also make the organization responsible for server administration, networking, security, and maintenance.Page 1
Question 2: Which operating-system platforms are identi�ed by the current 3CX Advanced Academy for self-installed on-premise deployments?
Choices:
1) Windows and Linux 2) Windows and macOS 3) Linux and FreeBSD 4) macOS and Linux
Correct Answer: Windows and Linux
Explanation: The current Advanced Academy speci�cally covers installing 3CX on Windows or Linux for on-premise deployments.
Question 3: An administrator is sizing a self-hosted 3CX server. What planning
consideration is most important before choosing the smallest acceptable hardware?
Choices:
1) Only the current number of extensions matters 2) Future growth and simultaneous-call requirements should be considered 3) The public FQDN determines CPU requirements 4) The SIP trunk provider determines the server disk size Correct Answer: Future growth and simultaneous-call requirements should be considered Explanation: 3CX training emphasizes sizing hardware for the deployment and allowing for future growth because later server upgrades may be disruptive or di�cult.Page 2
Question 4: Which statement best re�ects 3CX support responsibility for a self- hosted or on-premise installation?
Choices:
1) 3CX support covers every OS and hypervisor issue 2) 3CX manages the customer's �rewall automatically 3) The customer remains responsible for OS and machine-related issues 4) The SIP trunk provider is responsible for the operating system Correct Answer: The customer remains responsible for OS and machine-related issues Explanation: For self-hosted and on-premise systems, the customer controls the machine and operating environment. 3CX documentation notes that OS and machine-related issues are not covered in the same way as a 3CX-hosted deployment.
