Question 121<\/b><\/h3>\n

Which VRP view displays device operational commands?<\/b><\/p>\n

    \n
  1. Interface view<\/span><\/li>\n
  2. Protocol view<\/span><\/li>\n
  3. User view<\/span><\/li>\n
  4. System view<\/span><\/li>\n<\/ol>\n

    Correct Answer: 3<\/b><\/p>\n

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

    User view is the initial command-line environment on Huawei VRP devices. It provides access to basic monitoring and operational commands before entering deeper configuration views. From user view, an administrator can enter system view for configuration or access other available command contexts. Interface view is used for interface-specific settings, while system view handles broader device configuration. Understanding VRP’s hierarchical command structure is essential because the same command may only be available from a particular view.<\/span><\/p>\n

    Question 122<\/b><\/h3>\n

    Which route provides a backup path when preferred routes fail?<\/b><\/p>\n

      \n
    1. Connected route<\/span><\/li>\n
    2. Floating static route<\/span><\/li>\n
    3. Default interface<\/span><\/li>\n
    4. Host route<\/span><\/li>\n<\/ol>\n

      Correct Answer: 2<\/b><\/p>\n

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

      A floating static route is configured with a less-preferred route preference than the primary route. It remains inactive while the preferred route is available but can become selected when that route disappears. This provides a simple backup mechanism without requiring a dynamic routing protocol. Administrators commonly use floating static routes for redundant WAN or Internet connections. The key concept is that the backup route exists in the configuration but is intentionally given lower selection priority than the normal forwarding path.<\/span><\/p>\n

      Question 123<\/b><\/h3>\n

      Which OSPF identifier uniquely identifies a router?<\/b><\/p>\n

        \n
      1. Router ID<\/span><\/li>\n
      2. Area ID<\/span><\/li>\n
      3. Process ID<\/span><\/li>\n
      4. Network ID<\/span><\/li>\n<\/ol>\n

        Correct Answer: 1<\/b><\/p>\n

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

        The OSPF Router ID uniquely identifies an OSPF router within the routing domain. It is represented as a 32-bit value written in IPv4 address format, although it is not necessarily an actual interface address. The Router ID participates in functions such as neighbor relationships and DR or BDR election. Administrators can explicitly configure a Router ID to make the identity predictable. If one is not manually configured, the router can select an appropriate address according to OSPF rules.<\/span><\/p>\n

        Question 124<\/b><\/h3>\n

        Which OSPF router is elected on broadcast networks?<\/b><\/p>\n

          \n
        1. ABR<\/span><\/li>\n
        2. ASBR<\/span><\/li>\n
        3. DR<\/span><\/li>\n
        4. Internal router<\/span><\/li>\n<\/ol>\n

          Correct Answer: 3<\/b><\/p>\n

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

          OSPF elects a Designated Router on broadcast multi-access networks. The DR reduces the number of full OSPF adjacencies required because routers can exchange certain information through the DR rather than forming full relationships with every neighbor. A Backup Designated Router is also elected to provide redundancy. The election is influenced by interface priority and Router ID. Understanding DR operation is important when troubleshooting OSPF neighbor relationships on Ethernet segments containing multiple routers.<\/span><\/p>\n

          Question 125<\/b><\/h3>\n

          Which OSPF device provides backup for the DR?<\/b><\/p>\n

            \n
          1. ABR<\/span><\/li>\n
          2. BDR<\/span><\/li>\n
          3. ASBR<\/span><\/li>\n
          4. LSR<\/span><\/li>\n<\/ol>\n

            Correct Answer: 2<\/b><\/p>\n

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

            The Backup Designated Router, or BDR, serves as the standby for the OSPF Designated Router on applicable multi-access networks. If the DR fails, the BDR can take over the DR role, reducing disruption to OSPF operations. A new BDR can then be elected as necessary. DR and BDR election occurs independently on each applicable network segment. Their use reduces the amount of adjacency overhead compared with having every router establish a full adjacency with every other router.<\/span><\/p>\n

            Question 126<\/b><\/h3>\n

            Which VLAN field identifies the tagged VLAN?<\/b><\/p>\n

              \n
            1. DSCP value<\/span><\/li>\n
            2. TCP port<\/span><\/li>\n
            3. 802.1Q tag<\/span><\/li>\n
            4. IP checksum<\/span><\/li>\n<\/ol>\n

              Correct Answer: 3<\/b><\/p>\n

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

              IEEE 802.1Q provides VLAN tagging information within an Ethernet frame. The tag contains VLAN identification information that allows switches to determine which VLAN the frame belongs to while it crosses a trunk link. This makes it possible for multiple VLANs to share the same physical connection between network devices. IP addresses and TCP ports operate at higher layers and do not provide the standard Layer 2 VLAN identification mechanism used by 802.1Q trunking.<\/span><\/p>\n

              Question 127<\/b><\/h3>\n

              Which command disables an interface administratively?<\/b><\/p>\n

                \n
              1. shutdown<\/span><\/li>\n
              2. disable port<\/span><\/li>\n
              3. port shutdown<\/span><\/li>\n
              4. interface down<\/span><\/li>\n<\/ol>\n

                Correct Answer: 1<\/b><\/p>\n

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

                On Huawei VRP, the shutdown command administratively disables an interface. This differs from a physical or protocol failure, where an interface may become unavailable because of a cable, transceiver, or neighboring-device problem. Administrators may intentionally shut down unused interfaces or temporarily disable a connection during maintenance. The opposite operation is performed with undo shutdown, which removes the administrative shutdown state. Checking administrative status is therefore an important step during interface troubleshooting.<\/span><\/p>\n

                Question 128<\/b><\/h3>\n

                Which command restores an administratively disabled interface?<\/b><\/p>\n

                  \n
                1. enable interface<\/span><\/li>\n
                2. no shutdown<\/span><\/li>\n
                3. undo shutdown<\/span><\/li>\n
                4. interface enable<\/span><\/li>\n<\/ol>\n

                  Correct Answer: 3<\/b><\/p>\n

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

                  Huawei VRP uses undo shutdown to remove an interface’s administrative shutdown state. After this command is applied, the interface can attempt to become operational if its physical connection and other required parameters are correct. This command is commonly used after maintenance or configuration work when an interface was intentionally disabled. If the interface remains down afterward, administrators should investigate physical connectivity, VLAN configuration, protocol status, or other relevant settings rather than assuming the problem is still administrative.<\/span><\/p>\n

                  Question 129<\/b><\/h3>\n

                  Which VLAN parameter identifies untagged ingress traffic?<\/b><\/p>\n

                    \n
                  1. MTU<\/span><\/li>\n
                  2. Router ID<\/span><\/li>\n
                  3. PVID<\/span><\/li>\n
                  4. Loopback ID<\/span><\/li>\n<\/ol>\n

                    Correct Answer: 3<\/b><\/p>\n

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

                    PVID, or Port VLAN ID, identifies the VLAN associated with untagged traffic entering a switch port. When an untagged frame arrives, the switch can associate it with the port’s configured PVID. This is especially important on access connections where endpoint traffic normally arrives without an 802.1Q tag. PVID behavior can also matter on trunk or hybrid configurations depending on the design. Incorrect PVID settings can result in traffic being placed into an unintended VLAN.<\/span><\/p>\n

                    Question 130<\/b><\/h3>\n

                    Which feature protects an STP root from lower-priority switches?<\/b><\/p>\n

                      \n
                    1. Loop protection<\/span><\/li>\n
                    2. Root protection<\/span><\/li>\n
                    3. Port isolation<\/span><\/li>\n
                    4. MAC protection<\/span><\/li>\n<\/ol>\n

                      Correct Answer: 2<\/b><\/p>\n

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

                      Root protection helps prevent an interface from becoming a path through which a superior BPDU could influence the intended STP root topology. It is useful on designated ports where administrators want to prevent an external or incorrectly configured switch from taking part in root selection. This strengthens control over the Layer 2 topology. Root protection should be applied according to the network design because its behavior can place a port into a protected state when unexpected superior BPDUs are received.<\/span><\/p>\n

                      Question 131<\/b><\/h3>\n

                      Which link aggregation mode actively negotiates LACP?<\/b><\/p>\n

                        \n
                      1. LACP static<\/span><\/li>\n
                      2. Manual aggregation<\/span><\/li>\n
                      3. Standalone mode<\/span><\/li>\n
                      4. Dynamic trunk<\/span><\/li>\n<\/ol>\n

                        Correct Answer: 1<\/b><\/p>\n

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

                        LACP static mode on Huawei devices uses LACP to negotiate and maintain an Eth-Trunk link aggregation relationship. Multiple physical interfaces can operate as members of one logical interface, providing combined capacity and redundancy. LACP exchanges protocol information to determine compatible aggregation members. Manual aggregation does not provide the same negotiation behavior. When troubleshooting an Eth-Trunk, administrators should verify that member interfaces have compatible configurations and that LACP negotiation is functioning correctly.<\/span><\/p>\n

                        Question 132<\/b><\/h3>\n

                        Which device connects customer networks to MPLS services?<\/b><\/p>\n

                          \n
                        1. P router<\/span><\/li>\n
                        2. PE router<\/span><\/li>\n
                        3. Core host<\/span><\/li>\n
                        4. Access point<\/span><\/li>\n<\/ol>\n

                          Correct Answer: 2<\/b><\/p>\n

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

                          A Provider Edge, or PE, router sits at the edge of an MPLS provider network and connects to customer-facing devices such as CE routers. The PE participates in service-provider functions and can maintain customer routing information according to the deployed MPLS architecture. P routers operate within the provider core and generally do not connect directly to customer networks. Understanding PE and P roles helps administrators interpret MPLS topology diagrams and identify where customer-provider routing interactions occur.<\/span><\/p>\n

                          Question 133<\/b><\/h3>\n

                          Which protocol discovers Ethernet neighbors without IP configuration?<\/b><\/p>\n

                            \n
                          1. OSPF<\/span><\/li>\n
                          2. LLDP<\/span><\/li>\n
                          3. DHCP<\/span><\/li>\n
                          4. DNS<\/span><\/li>\n<\/ol>\n

                            Correct Answer: 2<\/b><\/p>\n

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

                            LLDP operates at the data-link layer and can exchange device information between directly connected neighbors without requiring IP routing between them. This makes it useful for discovering physical and logical topology details even when Layer 3 connectivity is not yet configured. Network administrators can use LLDP information to identify neighboring device names, ports, and capabilities. OSPF and DNS depend on Layer 3 networking, while DHCP is primarily used for address and configuration assignment.<\/span><\/p>\n

                            Question 134<\/b><\/h3>\n

                            Which DHCP function forwards client requests between subnets?<\/b><\/p>\n

                              \n
                            1. DHCP pool<\/span><\/li>\n
                            2. DHCP client<\/span><\/li>\n
                            3. DHCP relay<\/span><\/li>\n
                            4. DHCP lease<\/span><\/li>\n<\/ol>\n

                              Correct Answer: 3<\/b><\/p>\n

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

                              A DHCP relay forwards DHCP messages between clients and a DHCP server located on another subnet. DHCP clients commonly begin communication using broadcast messages, and routers normally do not forward broadcasts between subnets. A relay agent provides the necessary intermediary function so centralized DHCP servers can serve clients across multiple network segments. This avoids requiring a separate DHCP server on every subnet. Correct relay configuration is especially important in routed enterprise networks with centralized address management.<\/span><\/p>\n

                              Question 135<\/b><\/h3>\n

                              Which DNS record identifies a mail server?<\/b><\/p>\n

                                \n
                              1. CNAME<\/span><\/li>\n

                              3. MX<\/span><\/li>\n
                              4. NS<\/span><\/li>\n<\/ol>\n

                                Correct Answer: 3<\/b><\/p>\n

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

                                An MX record identifies mail-exchange servers responsible for accepting email for a domain. DNS resolvers can use MX information to determine where mail delivery should be directed. CNAME records provide aliases, TXT records store text-based information, and NS records identify authoritative name servers. When troubleshooting email delivery, checking the domain’s MX records is an important step because incorrect or missing records can prevent senders from locating the appropriate mail infrastructure.<\/span><\/p>\n

                                Question 136<\/b><\/h3>\n

                                Which HTTP method commonly retrieves a resource?<\/b><\/p>\n

                                  \n
                                1. GET<\/span><\/li>\n

                                3. DELETE<\/span><\/li>\n
                                4. PATCH<\/span><\/li>\n<\/ol>\n

                                  Correct Answer: 1<\/b><\/p>\n

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

                                  The HTTP GET method is commonly used to request or retrieve a resource from a server. It is fundamental to web communication and is generally associated with reading information rather than modifying server-side state. POST is commonly used to submit data, DELETE requests removal of a resource, and PATCH is commonly used for partial modifications. Understanding basic HTTP methods is useful in network services and automation because many management interfaces and APIs rely on HTTP-based communication.<\/span><\/p>\n

                                  Question 137<\/b><\/h3>\n

                                  Which WLAN standard introduced Wi-Fi 6?<\/b><\/p>\n

                                    Correct Answer: 2<\/b><\/p>\n

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

                                    IEEE 802.11ax is associated with Wi-Fi 6. It introduced improvements designed to increase efficiency and performance, particularly in environments containing many wireless clients. Earlier standards include 802.11n and 802.11ac, while 802.11g is an older WLAN technology. Understanding WLAN generations helps administrators distinguish supported capabilities when selecting access points and client devices. Wireless performance also depends on factors such as channel conditions, client capabilities, configuration, and network density.<\/span><\/p>\n

                                    Question 138<\/b><\/h3>\n

                                    Which WLAN device provides wireless client connectivity?<\/b><\/p>\n

                                    4. NMS<\/span><\/li>\n<\/ol>\n

                                      Correct Answer: 3<\/b><\/p>\n

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

                                      An Access Point, or AP, provides the wireless radio interface through which client devices connect to a WLAN. In a controller-based architecture, the AP can be managed centrally by an Access Controller. A STA represents the client station itself, while an NMS is used for network management rather than direct wireless access. Understanding these roles is essential when designing WLANs because the AP provides the actual wireless access service while other components perform management or client functions.<\/span><\/p>\n

                                      Question 139<\/b><\/h3>\n

                                        Correct Answer: 1<\/b><\/p>\n

                                        IPv6 multicast addresses use the FF00::\/8 prefix. Multicast allows traffic to be delivered to a group of interested receivers rather than to a single destination. IPv6 uses multicast extensively for functions that would otherwise rely on broadcast in IPv4. FE80::\/10 is reserved for link-local addresses, FC00::\/7 represents unique local addressing, and 2000::\/3 is used for global unicast addresses. Correctly identifying these ranges is important when interpreting IPv6 configurations.<\/span><\/p>\n

                                          Correct Answer: 2<\/b><\/p>\n

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

                                          IPv6 static routing requires an administrator to manually configure the destination prefix and the appropriate forwarding information. Unlike dynamic routing protocols, static routes are not automatically learned from neighboring routers. They can be useful for simple topologies, default paths, or backup connectivity. NDP supports neighbor discovery, SLAAC assists address configuration, and DHCPv6 can provide configuration information to hosts. When using IPv6 static routes, administrators should verify the destination prefix and next-hop or outgoing-interface information carefully.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
