Mixed Deck — All ACP Topics Flashcards

Which feature allows seamless user connectivity across multiple access points in Aruba wireless networks?

Answer: ClientMatch

Aruba ClientMatch is a patented technology that optimizes client connectivity by ensuring devices are always connected to the best possible access point (AP) and radio on the network. It intelligently steers clients away from congested or underperforming APs, improving overall Wi-Fi performance and providing a seamless roaming experience across multiple access points.

A professional is asked to provide a reference for a former colleague applying for a senior network role, but has reservations about the colleague's technical accuracy under pressure. What is the most ethical approach?

Answer: Decline to serve as a reference rather than provide an inaccurate or misleading endorsement

Providing a misleading positive reference is dishonest; declining to serve as a reference is ethical when an honest reference would be unfavorable.

What is the primary function of Aruba's 'Air Monitor' (AM) mode?

Answer: To scan the RF environment for rogue APs and wireless threats without serving clients

An AP in Air Monitor mode dedicates its radios entirely to WIDS/WIPS scanning, detecting rogue APs, ad-hoc networks, and wireless attacks.

A change management process requires a 'back-out plan' for all Aruba configurations. What does this document describe?

Answer: Steps to revert the change if it causes problems

A back-out plan documents the exact steps to undo a change if it results in unintended consequences.

Which Aruba technology uses 6 GHz band spectrum introduced in Wi-Fi 6E to deliver additional non-overlapping channels?

Answer: Wi-Fi 6E extending 802.11ax into the 6 GHz band

Wi-Fi 6E extends the 802.11ax standard into the newly opened 6 GHz band, providing up to 1,200 MHz of additional spectrum with 59 non-overlapping 20 MHz channels in the US.

Which Aruba Central feature enables proactive quality assurance by predicting potential network issues before they impact users?

Answer: AI-powered anomaly detection and predictive analytics

Aruba Central's AI-powered analytics detect behavioral anomalies and predict issues before they escalate, supporting proactive QA.

An Aruba administrator notices high retry rates on 2.4 GHz. Which evaluation step should be performed FIRST?

Answer: Analyze the RF spectrum for non-Wi-Fi interference sources

High retry rates on 2.4 GHz often result from non-Wi-Fi interference (e.g., microwaves, Bluetooth), so spectrum analysis should be the first diagnostic step.

Which layer of the OSI model is responsible for end-to-end error detection, flow control, and segmentation?

Answer: Transport (Layer 4)

The Transport layer (Layer 4) handles end-to-end communication, segmentation, flow control, and error recovery via TCP or UDP.

An Aruba project team is conducting a Failure Mode and Effects Analysis (FMEA) on its controller cluster. What is the PRIMARY goal of FMEA?

Answer: To identify how each component can fail and assess the severity of each failure mode

FMEA systematically identifies potential failure modes for each component, their causes, and the severity of their effects on the overall system.

When building a multi-year wireless infrastructure roadmap, which strategic framework helps prioritize investments based on business impact and feasibility?

Answer: SWOT Analysis

SWOT Analysis evaluates Strengths, Weaknesses, Opportunities, and Threats to prioritize investments by balancing business impact with feasibility.

Which Aruba switching series is purpose-built for cloud-native, intent-based networking with a modern Linux-based OS?

Answer: Aruba CX Series (AOS-CX)

The Aruba CX switch series runs AOS-CX, a modern Linux-based, REST API-native operating system designed for automation and intent-based networking.

A network leader is building a business case for Aruba AIOps. Which benefit is most strategically compelling to a cost-conscious executive?

Answer: AIOps reduces mean time to resolution and decreases the number of Tier 2 escalations, lowering operational cost

Quantifiable reductions in MTTR and Tier 2 escalations directly translate to measurable labor cost savings and uptime improvements that resonate with cost-conscious executives.

When planning a network strategy for a merger integration, what should the network leader prioritize in the first 90 days?

Answer: Conduct a network assessment of both environments and develop an integration blueprint

A rapid assessment of both network environments followed by an integration blueprint establishes facts before committing to irreversible integration decisions.

A network program is over budget by 15% at the halfway milestone. What is the most appropriate leadership response?

Answer: Conduct a root cause analysis, present corrective options to sponsors, and reforecast the budget

Transparent root cause analysis followed by options presented to sponsors demonstrates accountable leadership and enables informed decision-making.

A CIO is reviewing IT vendor relationships and wants to reduce strategic risk. Which vendor management practice aligns with best-practice strategic planning?

Answer: Maintain a multi-vendor strategy with open standards to preserve negotiating leverage and avoid lock-in

A multi-vendor strategy with open standards reduces lock-in risk and preserves negotiating leverage, which is a core principle of strategic vendor management.

Which SSID design approach does Aruba recommend to reduce co-channel interference in high-density environments?

Answer: Minimize the number of SSIDs broadcast per AP to reduce beacon overhead

Each SSID adds beacon overhead and increases channel contention; Aruba recommends keeping the number of active SSIDs per AP to a minimum (typically 3 or fewer).

What is ECMP, and how does it benefit Aruba network designs?

Answer: Equal Cost Multi-Path — it load-balances traffic across multiple equal-cost routes simultaneously

ECMP (Equal Cost Multi-Path) allows routers to distribute traffic across multiple paths with identical routing costs, increasing throughput and providing redundancy.

What constitutes a boundary violation in professional practice?

Answer: Engaging in dual relationships that could impair professional judgment

Dual relationships that could impair professional judgment represent boundary violations, potentially compromising the quality and objectivity of professional services.

What is risk mitigation?

Answer: Taking actions to reduce the likelihood or impact of identified risks

Risk mitigation involves specific actions to reduce either the likelihood of risk occurrence or its potential impact, bringing residual risk to acceptable levels.

What is the purpose of Link Aggregation Control Protocol (LACP) in a network?

Answer: Bundle multiple physical links into one logical high-bandwidth channel

LACP (802.3ad) negotiates and manages link aggregation groups (LAGs), combining multiple physical interfaces for increased bandwidth and redundancy.
