3CX ACADEMY BASIC
CERTIFICATION PRACTICE
EXAM Question 1: A company with eight users wants the simplest 3CX option with minimal server administration. Which deployment best matches the current 3CX guidance?
Choices:
1) Use 3CX SMB hosted service 2) Build a dedicated on-premises Windows server 3) Deploy a private cloud VM with manual updates 4) Install a separate SBC as the PBX
Correct Answer: Use 3CX SMB hosted service
Explanation: 3CX recommends 3CX SMB for companies with fewer than 10 users. It is hosted and removes the need to manage the PBX instance and its underlying server.Page 1
Question 2: Which statement best describes Hosted by 3CX?
Choices:
1) 3CX operates and monitors the PBX hosting platform 2) The customer must supply and patch the operating system 3) It can only be used without SIP trunks 4) It requires every phone to use STUN
Correct Answer: 3CX operates and monitors the PBX hosting platform
Explanation: Hosted by 3CX places the PBX on infrastructure operated and monitored by 3CX, reducing the customer's hosting and server-management burden.
Question 3: An organization wants complete control of the virtual machine and
cloud provider used for its 3CX PBX. Which deployment model is most appropriate?
Choices:
1) 3CX SMB shared instance 2) Self-hosted private cloud 3) Hosted by 3CX only 4) Local router-phone mode
Correct Answer: Self-hosted private cloud
Explanation: A self-hosted private-cloud deployment lets the organization choose and manage the cloud environment while running its own 3CX instance.Page 2
Question 4: Before deploying 3CX on premises, which network task is especially
important for successful SIP and remote-app connectivity?
Choices:
1) Run and verify the 3CX Firewall Checker 2) Disable DNS resolution 3) Block all UDP tra�c 4) Use dynamic NAT mappings for every media packet
Correct Answer: Run and verify the 3CX Firewall Checker
Explanation: On-premises installations depend on correct �rewall and NAT behavior. 3CX speci�cally recommends running the Firewall Checker to verify required connectivity.
Question 5: Why is a stable public FQDN important for a 3CX system?
Choices:
1) It provides a consistent hostname for secure access and services 2) It replaces the need for any IP routing 3) It automatically creates SIP trunk credentials 4) It converts analog extensions to SIP Correct Answer: It provides a consistent hostname for secure access and services Explanation: A stable FQDN gives users, apps, phones and services a consistent hostname for reaching the PBX and supports secure certi�cate-based access.Page 3
