Question 341.

What is the primary purpose of validating network assumptions before final implementation?

1. Confirm that key design decisions are based on accurate information
2. Eliminate the need for testing
3. Replace the detailed design
4. Prevent all future requirement changes

Correct Answer: 1. Confirm that key design decisions are based on accurate information

Explanation:

Presales designs often rely on assumptions about user counts, traffic levels, cabling, power, application behavior, or available infrastructure. Before implementation, these assumptions should be validated wherever possible because an incorrect assumption may affect sizing, compatibility, or migration planning. If a major assumption changes, the design and bill of materials may need revision. Validation improves technical accuracy and reduces the risk of discovering important differences during installation.

Question 342.

Why should a final design review include representatives from implementation and operations teams?

1. To remove customer involvement
2. They can identify deployment and operational issues that may not be obvious during initial architecture design
3. To replace the presales engineer
4. To avoid documenting the solution

Correct Answer: 2. They can identify deployment and operational issues that may not be obvious during initial architecture design

Explanation:

Implementation teams understand practical deployment constraints, while operations teams focus on manageability, monitoring, support, and lifecycle requirements. Their input can reveal issues involving cabling, staging, maintenance, management access, software standards, or support procedures. Including these perspectives in the final review improves the likelihood that the proposed architecture is not only technically sound but also practical to deploy and operate.

Question 343.

What is the main purpose of verifying network-management reachability before a large rollout?

1. Increase device forwarding capacity
2. Replace routing protocols
3. Ensure devices can communicate with the systems used for monitoring, configuration, and automation
4. Increase WLAN coverage

Correct Answer: 3. Ensure devices can communicate with the systems used for monitoring, configuration, and automation

Explanation:

Centralized management depends on reliable connectivity between managed devices and management platforms. If routing, firewalls, DNS, certificates, or access-control policies block this communication, devices may fail to register or receive configurations. Presales and implementation teams should verify management-plane connectivity before large-scale deployment. Doing so is especially important when zero-touch provisioning or centralized automation is part of the solution.

Question 344.

Which approach BEST reduces risk when deploying a new configuration template to hundreds of devices?

1. Push it to every device without review
2. Disable configuration backups
3. Ignore site-specific variables
4. Validate the template, test it on a limited group, monitor results, and then expand deployment**

Correct Answer: 4. Validate the template, test it on a limited group, monitor results, and then expand deployment

Explanation:

Templates improve consistency but can also distribute an error rapidly if they are not validated. A safer approach is to perform syntax and policy checks, test the configuration in a lab or pilot group, verify the outcome, and then expand the rollout in stages. Configuration backups and rollback mechanisms should also be available. This controlled process preserves the efficiency benefits of automation while reducing widespread operational risk.

Question 345.

What is the primary purpose of validating a network’s management-plane security?

1. Protect administrative access and management communications from unauthorized use
2. Increase fiber transmission distance
3. Replace user authentication
4. Increase switch port count

Correct Answer: 1. Protect administrative access and management communications from unauthorized use

Explanation:

The management plane provides powerful access to network infrastructure, making it an important security target. Administrators should use secure protocols, strong authentication, appropriate authorization, restricted source networks, and logging. Where required, management traffic can also be separated from ordinary user traffic. Presales engineers should include management security in the solution architecture rather than treating it as a minor post-deployment configuration task.

Question 346.

Why should unused network services or management protocols be disabled when practical?

1. They always increase throughput
2. Reducing unnecessary services can lower the attack surface and simplify operations
3. Every available feature must remain enabled
4. It eliminates the need for security policy

Correct Answer: 2. Reducing unnecessary services can lower the attack surface and simplify operations

Explanation:

Each enabled management service or protocol creates another function that must be secured, maintained, and monitored. If a service is not required, disabling it can reduce unnecessary exposure and simplify the device configuration. This principle is part of basic infrastructure hardening. Presales and operations teams should balance security with operational needs and confirm that required support or management functions remain available.

Question 347.

What is the main purpose of applying least privilege to network administrator accounts?

1. Give every administrator complete control
2. Remove all administrative accounts
3. Limit each administrator to the permissions required for assigned responsibilities
4. Increase device processing performance

Correct Answer: 3. Limit each administrator to the permissions required for assigned responsibilities

Explanation:

Least privilege reduces the risk of accidental or unauthorized changes by limiting administrator permissions to what is necessary. A monitoring operator may need only read access, while another role may be authorized to change specific configurations. Centralized authentication and role-based authorization can help enforce these distinctions. Logging administrative actions further improves accountability and supports troubleshooting or audits.

Question 348.

Why should privileged network accounts be reviewed periodically?

1. Account privileges never change
2. Reviews are required only after outages
3. They increase bandwidth
4. Staff roles and access needs can change, leaving unnecessary permissions if accounts are not reviewed**

Correct Answer: 4. Staff roles and access needs can change, leaving unnecessary permissions if accounts are not reviewed

Explanation:

Employees may change teams, responsibilities, or leave the organization. Without periodic review, old accounts or excessive privileges can remain active longer than needed. Access reviews help ensure that permissions still match current job responsibilities. This supports least privilege and reduces security risk. The process should include local device accounts as well as centralized administrator identities where applicable.

Question 349.

What is the primary purpose of monitoring authentication failures on network infrastructure?

1. Detect possible access problems or suspicious attempts to reach protected systems
2. Increase AP capacity
3. Replace access controls
4. Determine cable length

Correct Answer: 1. Detect possible access problems or suspicious attempts to reach protected systems

Explanation:

Repeated authentication failures may indicate incorrect credentials, configuration problems, expired accounts, or unauthorized access attempts. Monitoring these events helps operations and security teams identify patterns that require investigation. Logs should include useful timestamps and source information where supported. Authentication monitoring complements preventive controls because it provides visibility into unsuccessful attempts and potential operational issues.

Question 350.

Why is centralized logging useful in a distributed enterprise network?

1. It eliminates network devices
2. It allows events from many systems to be collected and analyzed from a common location
3. It increases routing-table capacity
4. It removes the need for time synchronization

Correct Answer: 2. It allows events from many systems to be collected and analyzed from a common location

Explanation:

Distributed networks generate logs on switches, routers, controllers, security systems, and management platforms. Centralizing these records makes it easier to search events, correlate problems, maintain retention, and perform security analysis. Reliable time synchronization improves correlation because events from different systems can be placed in the correct sequence. Central logging also reduces dependence on local device storage, which may be limited.

Question 351.

What is the main purpose of monitoring routing-protocol neighbor status?

1. Increase PoE power
2. Replace route tables
3. Detect loss or instability of important routing relationships
4. Configure wireless roaming

Correct Answer: 3. Detect loss or instability of important routing relationships

Explanation:

Dynamic routing depends on relationships between neighboring devices. If a routing adjacency repeatedly fails or remains down, reachable networks may be lost or traffic may move to less desirable paths. Monitoring neighbor state allows operations teams to detect these conditions quickly. Repeated changes can also indicate unstable links, configuration problems, software issues, or resource constraints that require deeper investigation.

Question 352.

What is the main purpose of monitoring link flaps?

1. Increase interface speed
2. Replace physical inspection
3. Eliminate redundancy
4. Identify interfaces that repeatedly transition between up and down states**

Correct Answer: 4. Identify interfaces that repeatedly transition between up and down states

Explanation:

A link that repeatedly changes state can disrupt routing, switching, applications, and redundancy protocols even if it is not permanently down. Causes can include faulty cabling, unstable optics, power issues, provider problems, or configuration errors. Monitoring link flaps helps engineers recognize intermittent faults that may otherwise be difficult to diagnose. Historical event data is especially useful for identifying frequency and timing patterns.

Question 353.

What is the primary purpose of monitoring packet drops on network interfaces?

1. Identify congestion or other conditions causing traffic to be discarded
2. Increase available bandwidth
3. Replace application monitoring
4. Configure routing automatically

Correct Answer: 1. Identify congestion or other conditions causing traffic to be discarded

Explanation:

Packet drops can occur because of congestion, queue limits, interface errors, policing, hardware constraints, or other conditions. Persistent or significant drops may affect application performance even when the interface remains operational. Monitoring drop counters together with utilization, errors, QoS statistics, and application symptoms helps administrators determine the likely cause and whether capacity or configuration changes are required.

Question 354.

Why should CPU and memory utilization be monitored on network devices?

1. They determine fiber wavelength
2. High resource utilization can indicate overload, abnormal behavior, or insufficient platform capacity
3. Resource usage has no effect on network operation
4. They replace interface statistics

Correct Answer: 2. High resource utilization can indicate overload, abnormal behavior, or insufficient platform capacity

Explanation:

Routers, switches, controllers, and security systems depend on CPU and memory for control-plane functions, management, routing, and services. Sustained high utilization may lead to slow management response, protocol instability, or reduced performance. Administrators should understand normal baseline levels and investigate significant deviations. CPU and memory data should be considered alongside traffic, logs, and enabled features to determine the underlying cause.

Question 355.

What is the main purpose of monitoring environmental sensors in network equipment?

1. Detect conditions such as temperature or fan problems before they cause service impact
2. Increase throughput automatically
3. Replace facility cooling
4. Configure VLANs

Correct Answer: 1. Detect conditions such as temperature or fan problems before they cause service impact

Explanation:

Network devices often include sensors that report temperature, fan status, voltage, or other environmental conditions. Monitoring these values provides early warning of cooling or hardware problems. Excessive temperature can reduce reliability or trigger protective shutdowns. Environmental monitoring is especially valuable in remote communication rooms where physical inspection is infrequent. It complements, rather than replaces, proper facility cooling and power design.

Question 356.

Why should PoE utilization be monitored after deployment?

1. It affects only IP addressing
2. It helps determine whether the remaining power budget is sufficient for current devices and future growth
3. PoE consumption never changes
4. Monitoring PoE replaces power-supply redundancy

Correct Answer: 2. It helps determine whether the remaining power budget is sufficient for current devices and future growth

Explanation:

The actual power consumed by APs, cameras, phones, and other endpoints may differ from initial estimates and can change when new devices are added. Monitoring PoE usage helps administrators see how much power capacity remains and whether certain switches are approaching their limits. This information supports future expansion planning and can reveal unexpected power demand before additional endpoints are deployed.

Question 357.

What is the primary purpose of periodically testing configuration restoration procedures?

1. Confirm that backups can actually be used to recover device configuration when needed
2. Eliminate configuration backups
3. Increase WAN throughput
4. Prevent all hardware failures

Correct Answer: 1. Confirm that backups can actually be used to recover device configuration when needed

Explanation:

A backup provides limited value if the organization does not know whether it can be located, accessed, and restored correctly. Periodic recovery testing confirms that backup files are usable and that administrators understand the restoration process. Testing may also reveal missing files, outdated procedures, or compatibility concerns. Recovery exercises should be performed in controlled conditions so they do not create unnecessary production risk.

Question 358.

Why is device-replacement documentation useful for critical network platforms?

1. Hardware never needs replacement
2. It provides clear steps for restoring service when a failed device must be replaced
3. It replaces vendor support
4. It eliminates inventory management

Correct Answer: 2. It provides clear steps for restoring service when a failed device must be replaced

Explanation:

Replacing a failed network device may require identifying compatible hardware, installing software, restoring configuration, reconnecting cables, applying licenses, and validating services. Documented procedures reduce recovery time because engineers do not need to reconstruct these steps during an outage. The documentation should reference configuration backups, inventory, support processes, and post-replacement validation requirements.

Question 359.

What is the primary purpose of a periodic network resilience review?

1. Reassess whether redundancy and recovery mechanisms still match current business requirements
2. Eliminate all maintenance windows
3. Replace capacity planning
4. Increase device port density

Correct Answer: 1. Reassess whether redundancy and recovery mechanisms still match current business requirements

Explanation:

Networks change over time as new services, sites, and dependencies are added. A resilience design that was sufficient several years ago may no longer protect today’s critical applications. Periodic review examines single points of failure, backup capacity, failover behavior, power, WAN diversity, controller redundancy, and recovery procedures. This helps ensure that availability measures evolve alongside the business rather than remaining tied to outdated assumptions.

Question 360.

Which approach BEST supports secure and resilient operation of a Huawei enterprise network after deployment?

1. Depend only on the original design document
2. Disable monitoring to reduce operational overhead
3. Allow configuration changes without review
4. Combine secure management, centralized logging, health monitoring, configuration backup, recovery testing, controlled changes, and periodic resilience reviews**

Correct Answer: 4. Combine secure management, centralized logging, health monitoring, configuration backup, recovery testing, controlled changes, and periodic resilience reviews

Explanation:

Reliable operations require ongoing controls rather than a one-time deployment effort. Secure management protects administrative access, centralized logging supports troubleshooting and auditing, and health monitoring identifies developing problems. Configuration backups and tested recovery procedures reduce restoration time, while controlled changes lower the risk of avoidable outages. Periodic resilience reviews ensure that redundancy and recovery mechanisms continue to match the organization’s evolving business and technical requirements.
