3CX ACADEMY, BASIC CERTIFICATION | WITH 100% CORRECT ANSWERS
GRADED A+ GUARANTEED SUCCESS!! NEWEST 2026 COMPLETE QUESTIONS
Question 1
Which browser is officially listed as incompatible with the 3CX Management Console?
A) Google Chrome
B) Microsoft Edge
C) Mozilla Firefox
D) Internet Explorer
E) All of the above are compatible
Correct Answer: D) Internet Explorer
Rationale: 3CX utilizes modern web technologies and WebRTC standards that are not
supported by Internet Explorer. Users must use Chrome, Edge, or Firefox for full
functionality.
Question 2
When choosing a server to host 3CX, which of the following software applications is considered
"Incompatible" and should not be present?
A) Microsoft Word
B) Microsoft Exchange Server
C) Adobe Acrobat
D) VLC Player
E) Wireshark
Correct Answer: B) Microsoft Exchange Server
Rationale: Exchange Server is highly resource-intensive and often claims the same web
ports (80/443) and memory resources required by 3CX, leading to system instability.
Question 3
Why is it mandatory to request a different server if the proposed host already runs a DNS Server?
A) 3CX only works on Linux.
B) DNS servers require 32-bit architecture.
C) Running a DNS server on the same machine creates conflicts with 3CX port requirements and
FQDN management.
D) DNS servers disable the .Net framework.
E) 3CX has a built-in DNS that cannot be disabled.
Correct Answer: C) Running a DNS server on the same machine creates conflicts with 3CX
port requirements and FQDN management.
Rationale: 3CX management of its FQDN and internal routing can be severely disrupted by
the presence of a local DNS role on the same Windows instance.
Question 4
Which of the following is a supported architecture for installing 3CX?
A) 16-bit
, 2
B) 32-bit (x86)
C) 64-bit (x64)
D) ARM 32-bit only
E) Any architecture is supported
Correct Answer: C) 64-bit (x64)
Rationale: 3CX is a 64-bit application. It cannot be installed on 32-bit operating systems like
Windows 10 x86.
Question 5
What is the recommended action regarding unused network interfaces (NICs) on a 3CX server?
A) Leave them enabled for backup.
B) Bridge them together.
C) Disable them.
D) Set them to a static IP in the same range.
E) Use them for the VPN endpoint.
Correct Answer: C) Disable them.
Rationale: 3CX binds to specific network adapters. Having multiple active NICs can cause
"multihomed" issues where SIP traffic or licensing heartbeat packets are sent out the
wrong interface.
Question 6
Which connection type is recommended for a 3CX server to ensure voice quality and stability?
A) Wireless (Wi-Fi)
B) Satellite
C) Wired (Ethernet)
D) Bluetooth tethering
E) Both Wired and Wireless are equally recommended
Correct Answer: C) Wired (Ethernet)
Rationale: VoIP is highly sensitive to jitter and packet loss. Wireless connections are prone
to interference and latency spikes that "wired" connections typically avoid.
Question 7
If you are installing 3CX on a "Bare Metal" (physical) server, which method should you use?
A) PBXexpress
B) 3CX ISO
C) Windows Update
D) Manual file copy
E) apt-get install 3cx
Correct Answer: B) 3CX ISO
Rationale: The 3CX ISO is the standard deployment method for bare metal hardware and
local hypervisors, providing a optimized Debian-based OS and the PBX software.

Question 8
Which tool should be used to install 3CX on cloud providers like Google Cloud or Amazon
EC2?
A) 3CX ISO
B) PBXexpress
C) FTP upload
D) Command Prompt
E) Active Directory
Correct Answer: B) PBXexpress
Rationale: PBXexpress is 3CX’s automated wizard for deploying instances to major cloud
providers like Google Cloud, AWS, OVH, and 1&1.
Question 9
What is the minimum version requirement for VMware ESXi to be a compatible host for 3CX?
A) ESXi 3.0
B) ESXi 4.1
C) ESXi 5.0 or higher
D) ESXi 7.0 only
E) Any version of ESXi
Correct Answer: C) ESXi 5.0 or higher
Rationale: 3CX virtualization requirements specify VMware ESXi version 5.0 or later to
ensure the virtual hardware supports the PBX operations.
Question 10
Which of the following is NOT a compatible virtualization platform for 3CX?
A) Microsoft Hyper-V (>2008 R2)
B) KVM
C) Citrix XenServer (>7.0)
D) VirtualBox (for production)
E) VMware ESXi (>5.0)
Correct Answer: D) VirtualBox (for production)
Rationale: While VirtualBox might work for very small tests, it is not listed as a
supported/compatible production hypervisor like Hyper-V, ESXi, KVM, or XenServer.
Question 11
In an RFC-compliant internal network required by 3CX, which of the following IP ranges is
valid?
A) 11.x.x.x
B) 192.168.x.x
C) 172.15.x.x
D) 100.x.x.x
