Question 61.<\/b><\/p>\n

In an enterprise network proposal, why is oversubscription considered when designing access-to-aggregation uplinks?<\/b><\/p>\n

    \n
  1. <\/b> Because not all access ports are expected to transmit at full line rate simultaneously<\/span><\/li>\n
  2. <\/b> Because uplinks must always be slower than access ports<\/span><\/li>\n
  3. <\/b> Because oversubscription removes the need for redundancy<\/span><\/li>\n
  4. <\/b> Because it determines the WLAN SSID name<\/span><\/li>\n<\/ol>\n

    Correct Answer: 1. Because not all access ports are expected to transmit at full line rate simultaneously<\/b><\/p>\n

    Explanation:<\/b><\/p>\n

    Oversubscription reflects the assumption that endpoint ports usually do not all transmit at their maximum rate at the same time. This allows the designer to use uplink capacity that is lower than the combined theoretical capacity of all access ports while still meeting expected demand. The appropriate ratio depends on application behavior, user density, wireless traffic, server access, and future growth. Critical or high-throughput environments may require lower oversubscription than ordinary office access networks.<\/span><\/p>\n

    Question 62.<\/b><\/p>\n

    What is the main purpose of traffic-flow analysis during network planning?<\/b><\/p>\n

      \n
    1. <\/b> Determine switch chassis color<\/span><\/li>\n
    2. <\/b> Understand where traffic originates, where it goes, and how much capacity paths may require<\/span><\/li>\n
    3. <\/b> Replace all network monitoring<\/span><\/li>\n
    4. <\/b> Determine only the number of VLAN names<\/span><\/li>\n<\/ol>\n

      Correct Answer: 2. Understand where traffic originates, where it goes, and how much capacity paths may require<\/b><\/p>\n

      Explanation:<\/b><\/p>\n

      Traffic-flow analysis helps identify how users, applications, data centers, internet services, branches, and cloud resources communicate. This information is important because two networks with the same number of users can have very different bandwidth requirements depending on traffic patterns. Presales engineers can use flow expectations to size uplinks, WAN connections, core capacity, and redundancy. It also helps identify potential bottlenecks and where QoS or local internet breakout may provide value.<\/span><\/p>\n

      Question 63.<\/b><\/p>\n

      Which requirement is MOST important when designing a campus network for real-time video conferencing?<\/b><\/p>\n

        \n
      1. <\/b> Low latency, adequate bandwidth, limited packet loss, and predictable QoS<\/span><\/li>\n
      2. <\/b> Maximum number of VLAN names<\/span><\/li>\n
      3. <\/b> Highest possible rack height<\/span><\/li>\n
      4. <\/b> Minimum number of management users<\/span><\/li>\n<\/ol>\n

        Correct Answer: 1. Low latency, adequate bandwidth, limited packet loss, and predictable QoS<\/b><\/p>\n

        Explanation:<\/b><\/p>\n

        Video conferencing depends on consistent network performance. Excessive latency, jitter, congestion, or packet loss can produce frozen video, distorted audio, and poor user experience. The design should provide sufficient access and uplink bandwidth, reliable wireless coverage where applicable, appropriate QoS classification and scheduling, and resilient paths. Presales engineers should also consider internet or WAN performance because end-to-end quality depends on more than the local campus infrastructure.<\/span><\/p>\n

        Question 64.<\/b><\/p>\n

        Why is east-west traffic important when designing a data center or large enterprise network?<\/b><\/p>\n

          \n
        1. <\/b> It describes only traffic going to the internet<\/span><\/li>\n
        2. <\/b> It refers only to wireless roaming<\/span><\/li>\n
        3. <\/b> It eliminates the need for switching capacity<\/span><\/li>\n
        4. <\/b> Significant server-to-server traffic can create high internal bandwidth requirements**<\/span><\/li>\n<\/ol>\n

          Correct Answer: 4. Significant server-to-server traffic can create high internal bandwidth requirements<\/b><\/p>\n

          Explanation:<\/b><\/p>\n

          East-west traffic generally refers to communication between systems within the data center or internal environment rather than traffic entering or leaving through the WAN or internet edge. Modern applications may generate substantial server-to-server communication because of distributed architectures, virtualization, storage, and application tiers. A design that focuses only on external traffic can underestimate internal bandwidth needs. High-capacity switching and appropriate topology are therefore important where east-west traffic is substantial.<\/span><\/p>\n

          Question 65.<\/b><\/p>\n

          What is the main benefit of a modular campus network architecture?<\/b><\/p>\n

            \n
          1. <\/b> Easier scaling and fault isolation between functional network blocks<\/span><\/li>\n
          2. <\/b> Elimination of routing protocols<\/span><\/li>\n
          3. <\/b> Removal of redundancy requirements<\/span><\/li>\n
          4. <\/b> Guaranteed zero congestion<\/span><\/li>\n<\/ol>\n

            Correct Answer: 1. Easier scaling and fault isolation between functional network blocks<\/b><\/p>\n

            Explanation:<\/b><\/p>\n

            A modular design divides the network into logical blocks such as access, aggregation, core, WAN, wireless, and data center connectivity. Each block can be scaled, upgraded, or troubleshot with less impact on unrelated parts of the network. Modularity also creates clearer boundaries for routing and policy. This is particularly useful in large enterprises where growth and operational changes are expected over many years.<\/span><\/p>\n

            Question 66.<\/b><\/p>\n

            Why should a presales engineer identify critical business applications during requirement gathering?<\/b><\/p>\n

              \n
            1. <\/b> To reduce the number of users<\/span><\/li>\n
            2. <\/b> To ensure performance, redundancy, and QoS are aligned with application importance<\/span><\/li>\n
            3. <\/b> To remove the need for capacity planning<\/span><\/li>\n
            4. <\/b> To select the network solely by product price<\/span><\/li>\n<\/ol>\n

              Correct Answer: 2. To ensure performance, redundancy, and QoS are aligned with application importance<\/b><\/p>\n

              Explanation:<\/b><\/p>\n

              Not every application has the same network requirements or business impact. Voice, payment systems, production applications, healthcare systems, or cloud-based business services may require higher availability and more predictable performance than ordinary background traffic. Identifying critical applications allows presales engineers to prioritize resilience, bandwidth, QoS, and monitoring accordingly. This ensures that technical investment is directed toward services that matter most to the customer’s operations.<\/span><\/p>\n

              Question 67.<\/b><\/p>\n

              What is the primary purpose of network baseline information?<\/b><\/p>\n

                \n
              1. <\/b> Replace all future measurements<\/span><\/li>\n
              2. <\/b> Determine the physical rack color<\/span><\/li>\n
              3. <\/b> Provide a reference for normal utilization and performance before changes are made<\/span><\/li>\n
              4. <\/b> Eliminate the need for capacity planning<\/span><\/li>\n<\/ol>\n

                Correct Answer: 3. Provide a reference for normal utilization and performance before changes are made<\/b><\/p>\n

                Explanation:<\/b><\/p>\n

                A network baseline records typical conditions such as interface utilization, latency, packet loss, CPU usage, memory use, wireless performance, and application traffic. This creates a reference point that can be compared with measurements after a new deployment or change. Baseline information helps distinguish genuine problems from normal variation and can improve capacity planning. In upgrade projects, existing performance data can also help presales engineers size the replacement solution more accurately.<\/span><\/p>\n

                Question 68.<\/b><\/p>\n

                Which factor should be considered when choosing between centralized and distributed internet access for branch sites?<\/b><\/p>\n

                  \n
                1. <\/b> Only the switch hostname<\/span><\/li>\n
                2. <\/b> Only the number of local printers<\/span><\/li>\n
                3. <\/b> Only the physical router color<\/span><\/li>\n
                4. <\/b> Application patterns, security architecture, WAN capacity, cloud usage, and operational policy**<\/span><\/li>\n<\/ol>\n

                  Correct Answer: 4. Application patterns, security architecture, WAN capacity, cloud usage, and operational policy<\/b><\/p>\n

                  Explanation:<\/b><\/p>\n

                  Centralized internet access can simplify security control but may force branch internet and cloud traffic through a headquarters or data center, consuming WAN bandwidth and potentially increasing latency. Local internet breakout can improve access to SaaS and cloud services but requires appropriate distributed security and policy enforcement. Presales engineers should evaluate application destinations, security requirements, link capacity, branch scale, and operational capabilities before recommending either model.<\/span><\/p>\n

                  Question 69.<\/b><\/p>\n

                  What is the primary purpose of a default gateway in an IP subnet?<\/b><\/p>\n

                    \n
                  1. <\/b> Forward traffic from local hosts toward destinations outside their subnet<\/span><\/li>\n
                  2. <\/b> Provide only DNS resolution<\/span><\/li>\n
                  3. <\/b> Increase wireless signal strength<\/span><\/li>\n
                  4. <\/b> Supply PoE power<\/span><\/li>\n<\/ol>\n

                    Correct Answer: 1. Forward traffic from local hosts toward destinations outside their subnet<\/b><\/p>\n

                    Explanation:<\/b><\/p>\n

                    A host sends packets directly to destinations in its own IP subnet. When the destination is outside that subnet, the host normally forwards the packet to its configured default gateway. The gateway, usually a router or Layer 3 switch, then routes the packet toward the destination. Because gateway availability is critical to user connectivity, enterprise designs often use first-hop redundancy or resilient Layer 3 architectures to protect this function.<\/span><\/p>\n

                    Question 70.<\/b><\/p>\n

                    Why might a campus design use Layer 3 routing between aggregation and core devices?<\/b><\/p>\n

                      \n
                    1. <\/b> To remove all IP addressing<\/span><\/li>\n
                    2. <\/b> To create clear failure boundaries and support scalable routed redundancy<\/span><\/li>\n
                    3. <\/b> To increase Layer 2 broadcast domains<\/span><\/li>\n
                    4. <\/b> To disable path diversity<\/span><\/li>\n<\/ol>\n

                      Correct Answer: 2. To create clear failure boundaries and support scalable routed redundancy<\/b><\/p>\n

                      Explanation:<\/b><\/p>\n

                      Using Layer 3 connections in the upper campus can limit the spread of Layer 2 failures and allow dynamic routing protocols to select alternate paths. Routed links can also simplify loop avoidance and make convergence behavior more predictable. The appropriate architecture depends on the campus scale, services, and virtualization technologies being used. Presales engineers should evaluate operational familiarity, redundancy requirements, and gateway placement before choosing a Layer 2 or Layer 3 boundary.<\/span><\/p>\n

                      Question 71.<\/b><\/p>\n

                      What is the main purpose of network access authentication?<\/b><\/p>\n

                        \n
                      1. <\/b> Verify users or devices before granting appropriate network access<\/span><\/li>\n
                      2. <\/b> Increase switching capacity<\/span><\/li>\n
                      3. <\/b> Replace routing protocols<\/span><\/li>\n
                      4. <\/b> Change fiber wavelength<\/span><\/li>\n<\/ol>\n

                        Correct Answer: 1. Verify users or devices before granting appropriate network access<\/b><\/p>\n

                        Explanation:<\/b><\/p>\n

                        Access authentication helps the network determine who or what is connecting before assigning permissions. Depending on the design, authentication can support employees, guests, contractors, and managed or unmanaged devices. The resulting identity information can be used with authorization policies to determine VLANs, access rights, or other network treatment. This strengthens campus security compared with granting identical access to every device connected to an Ethernet port or WLAN.<\/span><\/p>\n

                        Question 72.<\/b><\/p>\n

                        What is the main benefit of role-based network access control?<\/b><\/p>\n

                          \n
                        1. <\/b> It increases physical port speed<\/span><\/li>\n
                        2. <\/b> It allows access permissions to be based on user or device roles rather than only physical location<\/span><\/li>\n
                        3. <\/b> It replaces all endpoint security<\/span><\/li>\n
                        4. <\/b> It eliminates authentication<\/span><\/li>\n<\/ol>\n

                          Correct Answer: 2. It allows access permissions to be based on user or device roles rather than only physical location<\/b><\/p>\n

                          Explanation:<\/b><\/p>\n

                          Role-based access control associates permissions with identities or device categories instead of relying only on where a user connects. An employee, guest, printer, camera, or administrator can receive different network access even when connected through the same campus infrastructure. This can improve security and simplify policy management. The design typically depends on authentication, identity information, centralized policy, and integration with switching or wireless infrastructure.<\/span><\/p>\n

                          Question 73.<\/b><\/p>\n

                          Why should guest wireless traffic often be separated from internal enterprise traffic?<\/b><\/p>\n

                            \n
                          1. <\/b> To increase access point weight<\/span><\/li>\n
                          2. <\/b> To reduce the number of SSIDs to zero<\/span><\/li>\n
                          3. <\/b> To limit guest access to internal resources and enforce appropriate security policy<\/span><\/li>\n
                          4. <\/b> To disable internet access<\/span><\/li>\n<\/ol>\n

                            Correct Answer: 3. To limit guest access to internal resources and enforce appropriate security policy<\/b><\/p>\n

                            Explanation:<\/b><\/p>\n

                            Guest users generally require internet connectivity but should not automatically receive access to sensitive internal systems. Separating guest traffic through dedicated VLANs, policies, tunnels, or other segmentation mechanisms allows the enterprise to enforce appropriate restrictions. Guest authentication, bandwidth control, logging, and acceptable-use requirements may also be relevant. Presales engineers should understand expected guest volume and security policy before determining the technical design.<\/span><\/p>\n

                            Question 74.<\/b><\/p>\n

                            What is the primary purpose of WLAN channel planning?<\/b><\/p>\n

                              \n
                            1. <\/b> Assign BGP AS numbers<\/span><\/li>\n
                            2. <\/b> Determine wired VLAN IDs only<\/span><\/li>\n
                            3. <\/b> Increase switch PoE budget<\/span><\/li>\n
                            4. <\/b> Reduce interference and improve efficient use of available radio spectrum**<\/span><\/li>\n<\/ol>\n

                              Correct Answer: 4. Reduce interference and improve efficient use of available radio spectrum<\/b><\/p>\n

                              Explanation:<\/b><\/p>\n

                              Wireless access points operating on overlapping channels can interfere with one another and reduce usable capacity. Channel planning aims to distribute radio channels efficiently while considering neighboring APs, external interference, channel width, regulatory constraints, and client density. Automated radio management can assist in larger deployments, but the physical environment still matters. Good channel design is essential for reliable WLAN performance and should be considered together with AP placement and transmit power.<\/span><\/p>\n

                              Question 75.<\/b><\/p>\n

                              What is a major reason to use the 5 GHz or higher-frequency bands where client support and regulations permit?<\/b><\/p>\n

                                \n
                              1. <\/b> Greater channel availability can support higher-capacity WLAN designs<\/span><\/li>\n
                              2. <\/b> They always provide longer range than lower frequencies<\/span><\/li>\n
                              3. <\/b> They eliminate walls and attenuation<\/span><\/li>\n
                              4. <\/b> They require no channel planning<\/span><\/li>\n<\/ol>\n

                                Correct Answer: 1. Greater channel availability can support higher-capacity WLAN designs<\/b><\/p>\n

                                Explanation:<\/b><\/p>\n

                                Higher-frequency Wi-Fi bands can provide more usable channels and greater capacity than the heavily used 2.4 GHz band. This can be beneficial in dense office, education, hospitality, and public environments. However, propagation characteristics differ, and higher frequencies may experience greater attenuation through walls or over distance. Presales engineers should therefore consider both capacity and coverage rather than assuming that one band is universally superior.<\/span><\/p>\n

                                Question 76.<\/b><\/p>\n

                                Why is AP mounting location important in a WLAN design?<\/b><\/p>\n

                                  \n
                                1. <\/b> It determines the BGP routing table<\/span><\/li>\n
                                2. <\/b> Physical placement affects signal propagation, interference, and coverage quality<\/span><\/li>\n
                                3. <\/b> It replaces power planning<\/span><\/li>\n
                                4. <\/b> It has no effect after the AP is powered on<\/span><\/li>\n<\/ol>\n

                                  Correct Answer: 2. Physical placement affects signal propagation, interference, and coverage quality<\/b><\/p>\n

                                  Explanation:<\/b><\/p>\n

                                  Wireless radio performance depends heavily on the physical environment. Walls, ceilings, metal structures, shelving, machinery, and building layout can attenuate or reflect signals. AP height and orientation also affect coverage. An access point placed in a poor location may provide weaker or less predictable service even if its specifications are otherwise suitable. Site surveys and appropriate mounting plans help align real-world radio behavior with the intended coverage and capacity requirements.<\/span><\/p>\n

                                  Question 77.<\/b><\/p>\n

                                  What is the primary purpose of a proof of concept in a complex network sales project?<\/b><\/p>\n

                                    \n
                                  1. <\/b> Validate important solution capabilities or assumptions before full deployment<\/span><\/li>\n
                                  2. <\/b> Replace all technical documentation<\/span><\/li>\n
                                  3. <\/b> Eliminate customer acceptance testing<\/span><\/li>\n
                                  4. <\/b> Guarantee that no future change will be required<\/span><\/li>\n<\/ol>\n

                                    Correct Answer: 1. Validate important solution capabilities or assumptions before full deployment<\/b><\/p>\n

                                    Explanation:<\/b><\/p>\n

                                    A proof of concept allows the customer and presales team to verify selected functions under controlled conditions before committing to a full implementation. It can test interoperability, performance, management workflows, wireless behavior, automation, or other critical requirements. A well-defined POC includes clear objectives and success criteria. It reduces technical uncertainty but does not replace detailed design, implementation testing, or ongoing operational validation.<\/span><\/p>\n

                                    Question 78.<\/b><\/p>\n

                                    What is the main purpose of acceptance criteria in a network project?<\/b><\/p>\n

                                    1. <\/b> Determine the color of equipment labels<\/span><\/li>\n
                                    2. <\/b> Define measurable conditions that indicate whether the delivered solution meets agreed requirements<\/span><\/li>\n
                                    3. <\/b> Remove the need for testing<\/span><\/li>\n
                                    4. <\/b> Replace the bill of materials<\/span><\/li>\n<\/ol>\n

                                      Correct Answer: 2. Define measurable conditions that indicate whether the delivered solution meets agreed requirements<\/b><\/p>\n

                                      Explanation:<\/b><\/p>\n

                                      Acceptance criteria translate project requirements into verifiable outcomes. Examples can include connectivity, redundancy, throughput, wireless coverage, application performance, management visibility, or failover behavior. Clearly defined criteria help the customer and implementation team agree on what successful delivery means. They should be realistic, measurable, and aligned with the original design assumptions. Without clear criteria, disagreements can arise even when the technical deployment is functioning.<\/span><\/p>\n

                                      Question 79.<\/b><\/p>\n

                                      Why should interoperability with existing equipment be evaluated during presales design?<\/b><\/p>\n

                                        \n
                                      1. <\/b> New equipment may need to work correctly with existing protocols, optics, authentication, management, or third-party systems<\/span><\/li>\n
                                      2. <\/b> All networking products are automatically identical<\/span><\/li>\n
                                      3. <\/b> Existing infrastructure never affects a new deployment<\/span><\/li>\n
                                      4. <\/b> Interoperability applies only to power cables<\/span><\/li>\n<\/ol>\n

                                        Correct Answer: 1. New equipment may need to work correctly with existing protocols, optics, authentication, management, or third-party systems<\/b><\/p>\n

                                        Explanation:<\/b><\/p>\n

                                        Many network projects upgrade only part of an existing environment. New Huawei equipment may therefore need to interoperate with existing routers, switches, wireless systems, authentication platforms, monitoring tools, or third-party services. Standards support helps, but feature behavior and implementation details still need verification. Presales engineers should identify integration boundaries early and recommend testing where compatibility is critical or uncertain.<\/span><\/p>\n

                                        Question 80.<\/b><\/p>\n

                                        Which approach BEST supports a technically complete and commercially accurate enterprise network proposal?<\/b><\/p>\n

                                          \n
                                        1. <\/b> Select products before gathering requirements<\/span><\/li>\n
                                        2. <\/b> Ignore existing infrastructure because it will eventually be replaced<\/span><\/li>\n
                                        3. <\/b> Size every component only for today’s minimum demand<\/span><\/li>\n
                                        4. <\/b> Validate business requirements, traffic, topology, interfaces, power, optics, licenses, redundancy, management, interoperability, and growth**<\/span><\/li>\n<\/ol>\n

                                          Correct Answer: 4. Validate business requirements, traffic, topology, interfaces, power, optics, licenses, redundancy, management, interoperability, and growth<\/b><\/p>\n

                                          Explanation:<\/b><\/p>\n

                                          A strong proposal considers the complete solution rather than only the primary hardware. Requirement gathering defines the business and technical objectives, traffic analysis supports sizing, and architecture establishes how components interact. Power, optics, interfaces, licenses, management, support, redundancy, and compatibility must then be validated in the bill of materials. Including reasonable growth capacity and documenting assumptions improves investment protection and reduces implementation surprises.<\/span><\/p>\n
