Question 201.

What is the primary purpose of a wireless capacity assessment in a high-density office?

1. Determine whether the WLAN can support the expected number of active users and their applications
2. Replace wired network planning entirely
3. Eliminate the need for channel planning
4. Determine the color of the access points

Correct Answer: 1. Determine whether the WLAN can support the expected number of active users and their applications

Explanation:

Wireless capacity planning evaluates whether the available radio resources can support expected client density and application demand. A design may provide excellent signal coverage yet still perform poorly if too many users compete for limited airtime. Engineers should consider concurrent users, application bandwidth, channel availability, AP capabilities, client types, interference, and uplink capacity. Capacity analysis is especially important in classrooms, conference areas, offices, and public spaces where many devices may be active simultaneously.

Question 202.

Why should channel width be considered carefully in an enterprise WLAN?

1. Wider channels always provide better results in every environment
2. Wider channels can increase potential throughput but reduce the number of non-overlapping channels available
3. Channel width affects only wired switches
4. Channel width determines the PoE standard

Correct Answer: 2. Wider channels can increase potential throughput but reduce the number of non-overlapping channels available

Explanation:

Using wider wireless channels can increase the potential throughput of an individual connection, but it also consumes more spectrum. In dense deployments, this can reduce the number of reusable channels and increase co-channel interference. Presales engineers should balance per-client throughput against overall system capacity. The optimal channel width depends on AP density, spectrum availability, client capabilities, interference, and application requirements rather than a simple preference for the widest possible channel.

Question 203.

What is the main purpose of controlling AP transmit power in an enterprise WLAN?

1. Increase switch forwarding capacity
2. Replace site surveys
3. Balance coverage, roaming behavior, and interference between neighboring access points
4. Configure WAN routing

Correct Answer: 3. Balance coverage, roaming behavior, and interference between neighboring access points

Explanation:

Transmit power affects how far an access point’s signal reaches and how strongly neighboring cells overlap. Excessively high power can increase interference and cause clients to remain associated with distant APs, while power that is too low can create coverage gaps. Proper power planning helps create predictable cell sizes and supports smoother roaming. Automated radio-management systems can assist, but the physical layout and expected user density still need to be considered.

Question 204.

What is the primary purpose of load balancing across wireless access points?

1. Replace wired uplinks
2. Eliminate authentication
3. Increase PoE voltage
4. Reduce situations where too many clients concentrate on one AP while nearby capacity is available**

Correct Answer: 4. Reduce situations where too many clients concentrate on one AP while nearby capacity is available

Explanation:

In dense WLAN deployments, clients may cluster around one access point even when nearby APs have available resources. Load-balancing mechanisms can help distribute clients more effectively, improving utilization of the wireless infrastructure. The result depends on client behavior, signal conditions, radio design, and supported WLAN features. Load balancing is therefore one component of capacity management and should not be viewed as a substitute for adequate AP density or sound channel planning.

Question 205.

What is the main purpose of wireless band steering?

1. Encourage capable clients to use a more appropriate radio band when multiple bands are available
2. Increase fiber distance
3. Replace authentication
4. Configure BGP attributes

Correct Answer: 1. Encourage capable clients to use a more appropriate radio band when multiple bands are available

Explanation:

Band steering can encourage dual-band or multi-band clients to use a preferred frequency band rather than remaining on a more congested one. This can improve spectrum utilization and reduce pressure on heavily used bands. The effectiveness of steering depends partly on client behavior because the endpoint ultimately participates in association decisions. It should be combined with proper AP placement, channel planning, and capacity design rather than used as the sole optimization mechanism.

Question 206.

Why is roaming performance important for voice-over-WLAN users?

1. Voice applications are unaffected by brief connectivity interruptions
2. Delays during AP transitions can cause audible disruption in real-time calls
3. Roaming applies only to wired users
4. Roaming determines optical module compatibility

Correct Answer: 2. Delays during AP transitions can cause audible disruption in real-time calls

Explanation:

Voice traffic is sensitive to interruption, delay, jitter, and packet loss. When a mobile user moves between AP coverage areas, a slow roaming process can create a noticeable gap in the call. Effective WLAN design therefore considers overlapping coverage, authentication behavior, radio planning, controller capabilities, and client support. Voice-over-WLAN environments generally require more careful mobility planning than applications that can tolerate short pauses.

Question 207.

What is the main purpose of WLAN interference analysis?

1. Determine router memory size
2. Configure VLAN names
3. Identify radio-frequency conditions that may reduce wireless performance
4. Replace network security

Correct Answer: 3. Identify radio-frequency conditions that may reduce wireless performance

Explanation:

Wireless performance can be affected by neighboring Wi-Fi networks, overlapping channels, non-Wi-Fi devices, building materials, and other radio-frequency sources. Interference analysis helps identify these conditions so channel selection, AP placement, channel width, or transmit power can be adjusted. Strong signal strength alone does not guarantee good performance if interference is high. This is why RF analysis is an important part of professional WLAN planning and troubleshooting.

Question 208.

What is the main purpose of a wireless predictive survey?

1. Guarantee actual performance without validation
2. Replace floor plans
3. Eliminate all installation testing
4. Estimate coverage and AP placement before physical deployment**

Correct Answer: 4. Estimate coverage and AP placement before physical deployment

Explanation:

A predictive wireless survey uses floor plans, building characteristics, AP specifications, and modeled propagation to estimate coverage and access-point placement before installation. It can help determine an initial AP count and identify likely weak areas. However, predictive models depend on assumptions about construction materials and environmental conditions. Post-installation validation or on-site surveys may therefore still be necessary to confirm that actual coverage and capacity meet the design objectives.

Question 209.

What is the primary purpose of a WAN bandwidth utilization report?

1. Show how heavily WAN circuits are being used and help identify capacity constraints
2. Configure user passwords
3. Replace routing protocols
4. Determine rack temperature

Correct Answer: 1. Show how heavily WAN circuits are being used and help identify capacity constraints

Explanation:

WAN utilization reports show how much of a circuit’s available capacity is being consumed over time. This information helps administrators identify recurring congestion, determine peak periods, and decide whether additional bandwidth is required. Reports may also reveal unexpected traffic patterns or the impact of new applications. Presales engineers can use historical WAN utilization as an important input when sizing replacement circuits or planning SD-WAN deployments.

Question 210.

What is the primary benefit of application-aware path selection in SD-WAN?

1. It eliminates all WAN circuits
2. It can direct applications over paths that best meet their performance or policy requirements
3. It removes the need for encryption
4. It guarantees unlimited bandwidth

Correct Answer: 2. It can direct applications over paths that best meet their performance or policy requirements

Explanation:

Application-aware path selection can use information such as latency, packet loss, jitter, business priority, or transport cost to choose an appropriate WAN path. A real-time application might use the path with better performance, while background traffic may use a lower-cost connection. This can improve application experience and make better use of multiple WAN links. The effectiveness of the design still depends on available transport capacity and accurate policy configuration.

Question 211.

What is the main purpose of WAN link-quality monitoring in an SD-WAN solution?

1. Evaluate characteristics such as latency, jitter, and packet loss so path decisions can respond to changing conditions
2. Replace all routing
3. Increase branch switch port count
4. Determine AP channel width

Correct Answer: 1. Evaluate characteristics such as latency, jitter, and packet loss so path decisions can respond to changing conditions

Explanation:

A WAN circuit can remain technically up while its performance becomes poor because of congestion, packet loss, or excessive latency. Link-quality monitoring measures these characteristics and can provide input to application-aware path selection. This allows the SD-WAN system to move suitable traffic away from a degraded connection while continuing to use healthy paths. Monitoring therefore provides more useful service information than simple link up/down status alone.

Question 212.

Why is local internet breakout attractive for some cloud-focused branch networks?

1. It forces all cloud traffic through headquarters
2. It can reduce unnecessary backhaul and improve access to internet-based applications
3. It eliminates the need for security
4. It disables centralized policy

Correct Answer: 2. It can reduce unnecessary backhaul and improve access to internet-based applications

Explanation:

When branch users consume large amounts of SaaS and public-cloud traffic, sending all traffic through a central data center can increase latency and consume WAN bandwidth. Local internet breakout allows selected traffic to access internet services more directly. However, the design must still enforce appropriate security, filtering, monitoring, and policy at the branch or through cloud-delivered services. Presales engineers should evaluate application patterns and security architecture before recommending local breakout.

Question 213.

What is the main purpose of an enterprise VPN across an untrusted WAN transport?

1. Increase the physical speed of the circuit
2. Replace addressing
3. Protect traffic between sites through secure logical connectivity
4. Eliminate all branch routers

Correct Answer: 3. Protect traffic between sites through secure logical connectivity

Explanation:

A VPN creates logical connectivity across a transport network that may not itself be trusted. Depending on the solution, encryption and authentication can protect data traveling between branches, headquarters, data centers, or cloud environments. The underlying circuit still determines available bandwidth and latency. Presales engineers should consider VPN scale, cryptographic performance, key management, redundancy, and operational integration when sizing devices for secure WAN connectivity.

Question 214.

Why should encryption performance be considered when sizing a WAN edge device?

1. Encryption never consumes device resources
2. It affects only switch rack height
3. It eliminates application traffic
4. High volumes of encrypted traffic can require significant processing capacity**

Correct Answer: 4. High volumes of encrypted traffic can require significant processing capacity

Explanation:

VPN encryption and decryption require computational resources. A device that can forward a high amount of unencrypted traffic may support a lower throughput when advanced security or encryption functions are enabled. Presales engineers should therefore evaluate performance under the intended service mix rather than relying solely on headline forwarding specifications. This is particularly important when branches use high-speed internet links or when most WAN traffic must be encrypted.

Question 215.

What is the main purpose of a firewall in an enterprise network architecture?

1. Enforce security policy between networks or security zones
2. Increase WLAN radio capacity
3. Replace access switches
4. Supply power to endpoints

Correct Answer: 1. Enforce security policy between networks or security zones

Explanation:

A firewall controls traffic between networks according to configured security policy. Depending on the platform, it may inspect sessions, applications, users, threats, or other characteristics. Firewalls are often placed at internet edges, data center boundaries, branch locations, or between internal security zones. Presales engineers should consider throughput, concurrent sessions, interface requirements, security services, redundancy, and expected traffic growth when incorporating firewall capabilities into a network design.

Question 216.

Why should firewall performance be evaluated with intended security features enabled?

1. Security inspection always increases raw throughput
2. Advanced inspection can consume resources and affect effective throughput
3. Firewall performance depends only on chassis size
4. Features never affect capacity

Correct Answer: 2. Advanced inspection can consume resources and affect effective throughput

Explanation:

Firewall throughput can vary depending on which security features are enabled. Functions such as application inspection, intrusion prevention, malware analysis, or encrypted-traffic processing may require additional computation. A presales engineer should therefore size the firewall based on the expected feature set and real traffic profile rather than using only a maximum theoretical forwarding number. Capacity reserve should also be included for growth and traffic peaks.

Question 217.

What is the primary purpose of high availability between two security gateways?

1. Maintain security services if one gateway becomes unavailable
2. Double every packet automatically
3. Remove the need for policy configuration
4. Eliminate software upgrades

Correct Answer: 1. Maintain security services if one gateway becomes unavailable

Explanation:

Security gateways can become critical dependencies because large amounts of traffic may pass through them. Deploying them in a high-availability arrangement can reduce service disruption if one device fails or requires maintenance. The design should consider state synchronization, link redundancy, power, upstream and downstream paths, and failover behavior. Presales engineers should ensure that the overall topology remains redundant rather than simply deploying two devices with shared single points of failure.

Question 218.

What is the main purpose of security-policy logging?

1. Increase interface bandwidth
2. Record relevant permitted or denied traffic events for operations and security analysis
3. Replace access control
4. Eliminate monitoring systems

Correct Answer: 2. Record relevant permitted or denied traffic events for operations and security analysis

Explanation:

Security-policy logs can show which traffic was permitted or denied, when the event occurred, and which source or destination was involved. These records help administrators troubleshoot access problems and security teams investigate suspicious behavior. Logging should be designed carefully because excessive logging can consume storage and processing resources. Centralized collection and retention policies can improve analysis, auditing, and correlation across multiple security and network devices.

Question 219.

Why should network and security policies be designed together?

1. Routing, segmentation, access, and security controls must work consistently to support intended communication
2. Security has no relationship to topology
3. Routing automatically replaces firewall policy
4. Network design should ignore application requirements

Correct Answer: 1. Routing, segmentation, access, and security controls must work consistently to support intended communication

Explanation:

A network can provide physical and logical connectivity while security policy determines which communication is actually permitted. If routing and security designs are developed independently, traffic may be routed toward a service but blocked unexpectedly, or segmentation may not align with intended trust boundaries. Coordinating addressing, VLANs, routing, zones, authentication, and access controls produces a more predictable architecture and simplifies troubleshooting.

Question 220.

Which approach BEST supports a secure, high-performance Huawei enterprise network design?

1. Focus only on raw interface speed
2. Ignore application behavior and security inspection
3. Use the same capacity assumptions for every site
4. Combine application analysis, capacity planning, WLAN and WAN optimization, segmentation, security policy, redundancy, monitoring, and growth planning**

Correct Answer: 4. Combine application analysis, capacity planning, WLAN and WAN optimization, segmentation, security policy, redundancy, monitoring, and growth planning

Explanation:

A complete enterprise solution must support performance, security, reliability, and operations together. Application analysis identifies service requirements, capacity planning ensures sufficient resources, and WLAN and WAN design address user connectivity. Segmentation and security policy control access, while redundancy protects important services. Monitoring provides visibility after deployment, and growth planning helps preserve investment. Treating these elements as one coordinated design produces a more predictable and sustainable network than optimizing any single component in isolation.
