1. Which of the following statements about the provisioning template of a phone is true?
A. The provisioning template of a phone is optional and not required for connection.
B. The provisioning template of a phone provides all the necessary information a phone requires to connect to
3CX.
C. The provisioning template of a phone is a hardware component that stores network credentials.
D. The provisioning template of a phone is only used for firmware updates.
Answer: B
Rationale: The statement is true because a provisioning template in 3CX contains all necessary
parameters (e.g., SIP credentials, server address, codecs) for a phone to register and function. Options
B, C, and D are false or misleading.
2. When installing 3CX using a Free Edition License Key, is it true that you cannot use your own
SMTP server and the 3CX SMTP Service will be used automatically?
A. True
B. False, you must configure your own SMTP server.
C. False, the 3CX SMTP Service is only used for paid editions.
D. False, you can choose between your own SMTP server and the 3CX SMTP Service.
Answer: A
Rationale: The statement is true because the Free Edition License Key restricts the use of a custom SMTP
server, forcing the use of the 3CX SMTP Service. This is a known limitation of the free version.
3. When a phone is connected to the network, it will be automatically provisioned without any
administrator intervention.
A. True, because the phone uses DHCP to obtain configuration automatically.
B. True, as long as the phone is connected to the same VLAN as the provisioning server.
C. True, because modern phones support zero-touch provisioning protocols.
D. False
Answer: D
Rationale: The statement is true because modern VoIP phones use protocols like DHCP and TFTP to
automatically obtain configuration and firmware without manual setup. This is a standard feature in
many enterprise phone systems.

5. If a 3CX SIP port has been changed to any port other than 5060, can phones be provisioned
using PnP?
A. False, because PnP only works on port 5060
B. True
C. False, because PnP requires a different protocol
D. False, because PnP only works with the default SIP port
Answer: B
Rationale: The statement is false because PnP provisioning typically relies on default SIP port 5060;
altering the port may disrupt automatic discovery unless manually configured.
6. A digital receptionist can be configured to route calls based on caller voice input.
A. True, but only if the system uses speech recognition software
B. True
C. False
D. True, as long as the caller's voice is recognized by the system
Answer: C
Rationale: A digital receptionist can indeed use voice recognition to route calls based on caller input,
making the statement true. The correct answer is B (True).
7. Where can the latest supported and recommended firmware for supported IP phones be
downloaded?
A. From the PHONES page of the 3CX Management Console
B. From the 3CX partner portal under Downloads
C. From the manufacturer's website directly
D. From the UPDATES page of the 3CX Management Console
Answer: D
Rationale: The statement is true as per 3CX documentation; the latest firmware for supported IP phones
is available on the Updates page of the 3CX Management Console. Options B, C, and D are incorrect
because the statement is accurate.

by the PBX.
A. Only if the caller is using a landline
B. True
Page 2
,C. True, but only for external calls

Rationale: The statement is false because Digital Reception typically uses DTMF tones to route calls, but
the destination is not chosen based on the tone received from the caller; rather, the PBX uses the tones to
navigate menus. The correct answer is False (F).
9. Is it possible to configure each extension with a different voicemail language?
A. Only if the system administrator enables multi-language support.
B. True
C. False, all extensions must use the same voicemail language.
D. True, but only for extensions that are assigned to a specific user group.
Answer: B
Rationale: The statement is true because modern VoIP systems allow per-extension voicemail language
settings, enabling personalized greetings and prompts for each user.
10. For production use, is it recommended to run 3CX Central over a dynamic public IP address?
A. No
B. Only if the system is behind a hardware firewall.
C. Yes, because dynamic IPs are more secure against targeted attacks.
D. Yes, as long as a dynamic DNS service is configured.
Answer: A
Rationale: A dynamic public IP address can change, causing connectivity issues for VoIP services like
3CX. Therefore, a static public IP or a fixed address via DDNS is recommended for production use.
11. Which of the following statements about 3CX is true?
A. 3CX can compress voicemail messages to reduce disk usage when the quota is reached.
B. 3CX can delete the oldest voicemail messages when the Voicemail disk space quota is reached.

is reached, making the statement true. The other options are false or incomplete descriptions.
12. How many Polling Strategies are available for selection in Ring Groups?
A. One

sequential (hunt) and simultaneous (ring all). Thus, the correct answer is A (True).
Page 3
, 13. A single digital receptionist can handle multiple calls simultaneously.
A. False, because multiple calls would cause system overload.
B. False, because digital receptionists require human intervention for each call.
C. True
D. False, because a digital receptionist can only handle one call at a time.
Answer: C
Rationale: A single digital receptionist typically handles one call at a time, not multiple simultaneously.
Therefore, the statement is false.
14. True or False: An IP phone may have a different time zone setting than the default time zone
configured in the 3CX Phone System.
A. True
B. False, because the time zone is set by the network and cannot be overridden.
C. False, because the IP phone always synchronizes its time zone with the 3CX server.
D. False, as IP phones are not capable of independent time zone configuration.
Answer: A
Rationale: An IP phone can have its own time zone setting independent of the 3CX server's default time
zone. This allows the phone to display the correct local time even if the server is in a different time zone.
15. Refer to the 3CX edition comparison page (https://www.3cx.com/ordering/pricing). Is it
possible to provision and use remote extensions with a 3CX Free Edition license key?
A. True

file.
A. False, because voice messages are only available as MP3 files.
B. True

Answer: B
Rationale: Voice message notifications can be sent to email with the message attached as a .wav file, as
this is a common feature in many VoIP systems. Therefore, the statement is true.
17. Which of the following sets of characters are configurable as menu options in digital
receptionists?
