QUESTION 57
During the sizing of an AICC solution, the Erlang B formula is primarily used to determine the required number of what specific resource, considering a target service level and acceptable blockage rate?

Number of concurrent agents

Number of IVR ports

Number of trunk lines (circuits)

Amount of storage for call recordings

QUESTION 58
What is the main technical advantage of using “OPUS” as an audio codec for VoIP in AICC?

It is a versatile codec that provides high quality at low bitrates and is well-suited for variable network conditions.

It is the oldest codec and has the widest compatibility.

It uses the most bandwidth, guaranteeing the best quality.

It is only used for video calls.

QUESTION 59
What is the ultimate goal of a well-designed AICC solution from a business perspective?

To enhance customer experience, improve operational efficiency, and drive business growth.

To reduce the number of agents employed.

To eliminate the need for a CRM system.

To have the most advanced technology.

QUESTION 60
When configuring a SIP trunk between the AICC solution and an ITSP (Internet Telephony Service Provider), which SIP message is sent by the AICC system to initiate a call?

INVITE

BYE

ACK

200 OK

QUESTION 61
Which factor has the greatest impact on the accuracy of a speech recognition (ASR) engine in the IVR?

The quality and clarity of the audio signal and the use of a well-tuned language model.

The volume of the caller’s voice.

The brand of the media server.

The time of day.

QUESTION 62
Which component in the AICC architecture is most directly responsible for translating a customer’s web chat text into a structured intent that can be used for automated responses or routing?

CTI Server

Natural Language Processing (NLP) Engine

ICD Router

Media Server

QUESTION 63
When designing an AICC solution for a business with highly seasonal peaks (e.g., holiday sales), which deployment model offers the greatest elasticity?

On-premises deployment with fixed capacity.

Cloud-based (SaaS) deployment that can scale up and down on demand.

Hybrid deployment with a fixed on-premises core.

A dedicated appliance.

QUESTION 64
What is the main technical challenge in implementing “screen sharing” within a video chat interaction in AICC?

The security risk of exposing sensitive information on the agent’s screen.

The additional bandwidth and processing power required to capture and transmit the screen content.

The inability of most web browsers to support screen sharing.

The integration with the CRM system.

QUESTION 65
When troubleshooting one-way audio issues in a SIP-based AICC deployment, what network configuration issue is most commonly the root cause?

Incorrect DNS settings on the UAP.

Asymmetric routing causing RTP streams to be blocked by a firewall.

The CTI server running low on memory.

The ICD routing rules being misconfigured.

QUESTION 66
A customer’s existing network has a strict firewall policy that only allows outbound HTTPS (TCP/443) connections. When integrating AICC’s UAP with a third-party CRM hosted in a public cloud, which integration method is most likely to succeed without requiring changes to the firewall’s inbound rules?

A direct, persistent SIP trunk connection from the CRM to the AICC CTI.

The UAP initiates outbound HTTPS/WebSocket connections to a cloud-based integration broker.

A site-to-site IPsec VPN tunnel between the customer’s data center and the cloud provider.

Using the CRM’s public REST API with inbound POST requests to the AICC application server.

QUESTION 67
What is the key technical advantage of using an “API-first” architecture in modern AICC solutions?

It simplifies integration with third-party systems and enables the creation of custom applications.

It eliminates the need for a SIP trunk.

It reduces the cost of hardware.

It makes the IVR prompts sound clearer.

QUESTION 68
When designing an AICC solution for a global enterprise, which factor is most important for ensuring consistent service levels across all regions?

Centralized management and monitoring with localized configuration where needed.

Using the same hardware in every data center.

Forcing all agents to work in the same time zone.

Using a single, global SIP trunk provider.

QUESTION 69
When designing the network for a cloud-based AICC deployment, what is the primary benefit of using a Direct Connect or Express Route type of service instead of the public internet?

It provides a private, dedicated network connection with more consistent bandwidth and lower latency.

It is always less expensive than using the public internet.

It removes the need for any firewall security policies.

It automatically provides a backup connection.

QUESTION 70
In the context of project management for an AICC implementation, what does the term “phased rollout” refer to?

Deploying the solution to groups of users or sites incrementally to mitigate risk.

Rolling back the software to a previous version.

Installing all components at once.

Training agents after the system is live.

QUESTION 71
What is the primary function of a “hunt group” in contact center routing?

To define a set of agents or queues that can be targeted by a single pilot number.

To manage outbound dialing campaigns.

To record calls for a specific group of agents.

To provide background music for callers on hold.

QUESTION 72
For a outbound collections campaign, which dialing mode provides the best balance between compliance (avoiding harassing calls) and agent efficiency by presenting the customer information before the call is placed?

Predictive Dialing

Preview Dialing

Progressive Dialing

Power Dialing

QUESTION 73
What is the key difference between “synchronous” and “asynchronous” communication channels in AICC?

Synchronous (e.g., voice, video) requires parties to be present simultaneously; asynchronous (e.g., email, SMS) does not.

Synchronous channels are faster than asynchronous channels.

Asynchronous channels are only for internal use.

There is no significant difference.

QUESTION 74
What is the main technical challenge in achieving “lip-sync” in video calls within the AICC UAP?

Synchronizing the audio and video streams so they are not noticeably out of alignment.

Compressing the video enough to save bandwidth.

Encoding the video in a format the browser can play.

Transferring the video call between agents.

QUESTION 75
In a Huawei AICC solution, the CTI (Computer Telephony Integration) server is responsible for the text-to- speech (TTS) conversion played in the IVR.

True

False
