Conference Call Skills Assessment — Questions and Answers

Question 1: What does a 'co-host' designation allow in a large conference call?

A backup dial-in connection for the host
Another participant to share meeting management controls with the original host (Correct answer)
A second speaker to broadcast simultaneously
An AI assistant to moderate questions

Correct answer: Another participant to share meeting management controls with the original host

A co-host receives administrative permissions to manage participants, mute attendees, and run breakout rooms, distributing moderation workload in large calls.

Question 2: What should you do if a disruptive intruder enters your meeting?

End the call and never meet again
Give them host controls
Ignore it and continue
Remove them and lock the meeting (Correct answer)

Correct answer: Remove them and lock the meeting

Removing the intruder and locking the meeting restores order and security.

Question 3: What is 'Zoom bombing' in the context of conference call security?

A deliberate audio feedback attack
Uninvited individuals joining and disrupting a meeting (Correct answer)
Overloading a server with conference requests
Sending malware through a meeting chat link

Correct answer: Uninvited individuals joining and disrupting a meeting

Zoom bombing refers to unauthorized users crashing a meeting, often to share offensive content or disrupt proceedings.

Question 4: Which signaling-related task is NOT defined by the WebRTC standard itself?

ICE candidate gathering
Media encryption
Codec negotiation format
The signaling channel mechanism (Correct answer)

Correct answer: The signaling channel mechanism

WebRTC deliberately leaves the signaling transport to the application, commonly using WebSocket or HTTP.

Question 5: What is the primary purpose of echo cancellation technology in conference calls?

To remove the speaker's own voice from their microphone pickup (Correct answer)
To compress audio for faster transmission
To mute background participants
To record the call for later playback

Correct answer: To remove the speaker's own voice from their microphone pickup

Echo cancellation filters out the feedback loop caused when a microphone picks up audio from a nearby speaker.

Question 6: What does end-to-end encryption (E2EE) ensure in a conference call?

The meeting auto-deletes after 24 hours
Only the participants can decrypt and hear the conversation, not the service provider (Correct answer)
Only the host can speak
The call is recorded in encrypted format

Correct answer: Only the participants can decrypt and hear the conversation, not the service provider

E2EE encrypts audio and video on the sender's device and only decrypts it on the recipient's device, preventing even the platform provider from eavesdropping.

Question 7: Which accessory is most effective at reducing jaw microphone noise during long conference calls?

Headset with boom microphone (Correct answer)
Built-in laptop speaker
Bluetooth earbuds only
External webcam mic

Correct answer: Headset with boom microphone

A headset with a boom microphone positions the mic close to the mouth, capturing voice clearly while ears receive audio cleanly without feedback.

Question 8: What does 'muting on entry' accomplish from a security and privacy perspective?

It prevents accidental audio leaks from participants in noisy or compromising environments (Correct answer)
It restricts who can share their screen
It hides participant names from the attendee list
It encrypts each participant's connection

Correct answer: It prevents accidental audio leaks from participants in noisy or compromising environments

Muting participants on entry stops accidental background conversations from being broadcast and prevents unintended disclosure of ambient sounds.

Question 9: Why should hosts disclose when a web conference is being recorded?

To slow the meeting down
It is purely decorative
It increases bandwidth
Consent and privacy compliance often require notice (Correct answer)

Correct answer: Consent and privacy compliance often require notice

Many jurisdictions require informing participants so they can consent to being recorded.

Question 10: Which US federal law requires consent to record phone calls, varying by state?

The Electronic Communications Privacy Act and applicable state wiretap laws (Correct answer)
The Freedom of Information Act
The First Amendment
The Telecommunications Act of 1996

Correct answer: The Electronic Communications Privacy Act and applicable state wiretap laws

The ECPA and various state wiretap statutes require either one-party or all-party consent to record conversations, with some states like California requiring all-party consent.

Question 11: What should a conference call invitation include to ensure full participant readiness?

Only the meeting link
A list of questions the host will ask each person
Login credentials for the host's account
Dial-in number, access code, agenda, and time zone (Correct answer)

Correct answer: Dial-in number, access code, agenda, and time zone

Including the dial-in number, access code, agenda, and time zone ensures participants have everything needed to join and prepare effectively.

Question 12: What does 'virtual background' technology allow a participant to do during a video call?

Blur their face for anonymity
Share their screen with a single click
Improve their camera's frame rate
Replace their real background with a custom image or video (Correct answer)

Correct answer: Replace their real background with a custom image or video

Virtual backgrounds use AI segmentation or green screen keying to substitute the participant's actual environment with any chosen image or video.

Question 13: What should a host do when a participant joins a sensitive meeting but is not recognized?

Immediately end the meeting
Ask the participant to identify themselves before proceeding, or remove them (Correct answer)
Mute all participants and continue
Switch to a different platform

Correct answer: Ask the participant to identify themselves before proceeding, or remove them

Verifying the identity of unrecognized attendees prevents inadvertent disclosure of confidential information to unauthorized persons.

Question 14: What is a 'green screen' used for in video conference setups?

To reduce bandwidth usage
To enable a custom virtual background without hardware limitations (Correct answer)
To improve camera autofocus
To provide a shared annotation surface

Correct answer: To enable a custom virtual background without hardware limitations

A physical green screen provides a uniform background for chroma-key software to replace with any virtual image cleanly.

Question 15: What is the purpose of a 'soundcheck' or audio test before a conference call begins?

To verify that the microphone and speakers are working correctly (Correct answer)
To assign participant roles
To test internet speed
To record the call in advance

Correct answer: To verify that the microphone and speakers are working correctly

A pre-call soundcheck confirms that audio input and output devices are selected correctly and functioning before participants join.

Question 16: How do you ensure that the meeting stays within the designated conference room time?

Specify a buffer period. (Correct answer)
What is the rush? People have another five minutes to wait.
Reduce the speaking duration for everyone by 50%
None of the above

Correct answer: Specify a buffer period.

Specifying a buffer period, such as scheduling a meeting for 50 minutes instead of a full hour, helps ensure the meeting concludes within its designated time. This allows for slight overruns, technical issues, or a brief transition before the next scheduled event. It's a practical time management strategy that prevents meetings from consistently running late and impacting subsequent commitments.

Question 17: Which practice protects against 'meeting credential stuffing' attacks on conferencing platforms?

Disabling the meeting lobby
Using the same password for simplicity
Sharing credentials only via email
Using strong unique passwords and enabling multi-factor authentication (MFA) (Correct answer)

Correct answer: Using strong unique passwords and enabling multi-factor authentication (MFA)

MFA and unique passwords prevent attackers from using leaked credential databases to gain unauthorized access to conference accounts.

Question 18: When should a presenter close unnecessary applications before starting a screen share?

Only after the meeting begins
Before starting the meeting, to prevent notifications and reduce lag (Correct answer)
After sharing the screen
When asked by the host

Correct answer: Before starting the meeting, to prevent notifications and reduce lag

Closing unused apps prevents embarrassing notifications from appearing on screen and frees CPU/GPU resources for smoother screen sharing.

Question 19: Which framework does WebRTC use to negotiate the best connection path between peers?

REST
ICE (Correct answer)
CORS
OAuth

Correct answer: ICE

ICE gathers and tests candidate address pairs to select the optimal connectivity path.

Question 20: When sharing your screen, what is a key privacy precaution?

Close personal apps and notifications beforehand (Correct answer)
Increase your monitor brightness
Turn off your microphone
Share only in full-screen mode

Correct answer: Close personal apps and notifications beforehand

Closing private windows and notifications prevents accidental exposure of sensitive content.

Question 21: Which is a good etiquette practice when joining a meeting late?

Turn on your camera and wave
Announce yourself loudly and ask for a recap
Enter quietly with mic muted and catch up via chat (Correct answer)
Interrupt the speaker to apologize

Correct answer: Enter quietly with mic muted and catch up via chat

Joining quietly while muted avoids disrupting the ongoing discussion.

Question 22: Which security feature prevents uninvited guests from joining a conference call even if they have the meeting link?

Call recording
Waiting room with host approval (Correct answer)
HD video mode
Breakout rooms

Correct answer: Waiting room with host approval

A waiting room holds all joiners until the host manually admits each person, blocking unauthorized attendees even with the correct link.

Question 23: Which practice helps prevent unauthorized recording of a confidential conference call?

Establishing a clear no-recording policy and disabling participant recording in settings (Correct answer)
Using a faster internet connection
Using a toll-free dial-in number
Scheduling calls during off-peak hours

Correct answer: Establishing a clear no-recording policy and disabling participant recording in settings

Administratively disabling participant recording rights and stating the no-recording policy prevents unauthorized captures of sensitive discussions.

Question 24: What is the purpose of 'HD video' mode in conferencing software?

To enable 3D video conferencing
To transmit at 720p or 1080p resolution for sharper facial detail (Correct answer)
To compress video for slower connections
To restrict who can turn on their camera

Correct answer: To transmit at 720p or 1080p resolution for sharper facial detail

Enabling HD video streams at 720p or 1080p resolution, making expressions and shared documents visually clearer for all participants.

Question 25: What is the main risk of leaving your microphone unmuted when not speaking?

Background noise distracts other participants (Correct answer)
Your video quality drops
Your screen share stops
The meeting ends early

Correct answer: Background noise distracts other participants

An open mic picks up typing, pets, and other sounds that disrupt the call.

Question 26: What is 'phishing via conferencing invites' and how can it be prevented?

Fake meeting invites containing malicious links — prevented by verifying sender identity before clicking (Correct answer)
Accidentally inviting the wrong person
Recording a call without permission
Sending calendar invites without a meeting link

Correct answer: Fake meeting invites containing malicious links — prevented by verifying sender identity before clicking

Attackers send spoofed meeting invitations with malicious URLs; employees should verify sender addresses and use official calendar integrations.

Question 27: In a HIPAA-compliant telehealth conference call, what must the conferencing platform provide?

Free dial-in numbers for patients
Unlimited recording storage
A signed Business Associate Agreement (BAA) and end-to-end encryption (Correct answer)
HD video with no data retention

Correct answer: A signed Business Associate Agreement (BAA) and end-to-end encryption

HIPAA requires that any vendor handling protected health information sign a BAA and implement appropriate technical safeguards including encryption.

Question 28: What is a 'unique meeting ID' and why is it important for security?

The call quality score assigned by the platform
The host's employee number
The room number where the call takes place
A one-time-use identifier that expires after the meeting, preventing link reuse (Correct answer)

Correct answer: A one-time-use identifier that expires after the meeting, preventing link reuse

Unique or single-use meeting IDs expire after use, so even if credentials leak, they cannot be used to crash future meetings.

Question 29: Which audio codec is widely considered high-definition (HD) quality in modern conference call platforms?

G.729
Opus (Correct answer)
G.711
GSM

Correct answer: Opus

The Opus codec supports wideband and fullband audio, making it the preferred HD voice codec in modern conferencing platforms.

Question 30: What is a best practice for generating meeting passwords for sensitive conference calls?

Reuse the same password for all recurring meetings
Use the host's employee ID number
Use the meeting topic as the password
Use a randomly generated alphanumeric code rather than simple words (Correct answer)

Correct answer: Use a randomly generated alphanumeric code rather than simple words

Random alphanumeric passwords are harder to guess or brute-force than predictable words, significantly reducing unauthorized access risk.
