NEW QUESTION # 18
R1 has four static routes, each of which has a reachable next hop. Given this static route configuration, what is the next hop of the route to 20.0.0.0/30 in R1's routing table?
Answer: B
Explanation:
All four configured static routes have the same destination prefix, 20.0.0.0/30, and the question states that every next hop is reachable. Huawei route selection first considers route preference when choosing among routes from the same or different route sources. For static routes, a smaller preference value means a higher priority. The four preferences shown are 60 for next hop 10.1.1.2, 70 for 10.1.2.2, 100 for 10.1.3.2, and 50 for
10.1.4.2. Because 50 is the smallest preference, the route through 10.1.4.2 is selected as the active route in the IP routing table. The other configured static routes can remain as lower-priority alternatives and may become active if the preferred route becomes invalid, depending on reachability and configuration. Equal-cost load balancing would require routes with the same relevant preference and cost after route selection. That is not the case here. Therefore, the next hop of the selected route to 20.0.0.0/30 is 10.1.4.2, making option A correct.
NEW QUESTION # 19
In the figure, the router only ensures network connectivity between the web client and server, and all devices are interconnected through Ethernet cables. When the web client sends an HTTP request to the web server, which layers ' header information in the HTTP request will the router check or modify? (Select all that apply)
Answer: A,D
Explanation:
A router performing conventional IP forwarding processes information primarily at the network layer and data link layer. Therefore, options A and D are correct.
At the data link layer, the router receives an Ethernet frame, examines its Layer 2 information, removes the incoming Ethernet encapsulation, and prepares a new Layer 2 frame for transmission through the outgoing interface.
At the network layer, the router examines the destination IP address, searches its routing table, selects an outgoing interface or next hop, and decreases the IPv4 Time to Live (TTL). It also updates the IPv4 header checksum.
The router does not normally examine HTTP application content or modify TCP transport information when performing standard routing. Those operations belong to higher-layer processing or additional services.
The HCIA-Datacom forwarding model distinguishes routing functions from transport-layer and application- layer processing.
NEW QUESTION # 20
The administrator runs the interface Eth-Trunk 1 command to create Eth-Trunk 1 on SW1 and SW2. After the network is stable, the administrator runs the display interface brief command on SW1, and finds that Eth- Trunk 1 is Down, the states of its member interfaces are normal, and the configuration on SW1 is correct. The possible cause is that the member interfaces on SW2 are not added to Eth-Trunk 1.
Answer: B
Explanation:
The uploaded key marks this statement TRUE, but the Huawei VRP operating behavior makes FALSE the technically correct answer as the question is written. Creating Eth-Trunk 1 with the interface Eth-Trunk 1 command does not, by itself, enable LACP. The default Eth-Trunk working mode is manual load balancing on the relevant VRP platforms. In manual mode, the local switch does not depend on LACP negotiation with the remote switch to decide whether locally added, physically Up member interfaces can make the aggregation operational. If SW1 ' s member interfaces are physically normal and correctly added to Eth-Trunk
1, failing to add the corresponding SW2 interfaces to its Eth-Trunk can certainly break end-to-end forwarding, but it is not in itself a sufficient explanation for the local Eth-Trunk on SW1 being Down. In LACP mode, missing peer membership can prevent correct aggregation because LACPDUs are not exchanged as expected.
Since LACP mode is not specified here, option B is the verified answer.
NEW QUESTION # 21
Assume that you cannot configure an IP address for GE1/0/1 on a Huawei switch. Which of the following commands can you run in the interface view to resolve this problem?
Answer: B
Explanation:
On Huawei switches, a physical Ethernet interface usually works as a Layer 2 switch port by default. A Layer
2 interface cannot be assigned an IP address directly. If an administrator wants to configure an IP address on such an interface, the interface must first be converted into a Layer 3 interface. The command used for this is undo portswitch, so option B is correct.
After this command is executed, the interface no longer behaves as a Layer 2 switching port and can then support Layer 3 features such as direct IP address configuration. Options A, C, and D are all Layer 2 port-type commands used to configure the interface as a trunk, access, or hybrid port. These commands do not solve the problem because they keep the interface operating at Layer 2. HCIA-Datacom emphasizes the difference between Layer 2 switching interfaces and Layer 3 routed interfaces on switches. Understanding when to use undo portswitch is important in campus network deployment, especially when configuring routed uplinks, management interfaces, or inter-device Layer 3 links on switches.
NEW QUESTION # 22
Huawei network devices such as switches and routers can establish NETCONF channels with iMaster NCE- Campus through DHCP. The DHCP server notifies DHCP clients of the URL/IP address and port number of iMaster NCE-Campus through Option_____. (Enter only digits.)
Answer:
Explanation:
148
Explanation:
Huawei uses DHCP Option 148 for IPv4-based plug-and-play or zero-touch deployment of devices to iMaster NCE-Campus. The DHCP server can include controller information in this vendor-specific option, allowing a switch, router, or cloud-managed AP to obtain the southbound address or URL of iMaster NCE-Campus together with the required management port. After the device receives normal addressing information and the Option 148 parameters, it can reach the controller and establish the management channel, including NETCONF-based management in supported deployment scenarios. Huawei documentation distinguishes this from IPv6 deployment, where Option 17 can be used for equivalent controller discovery. The Option 148 value commonly carries fields such as the controller management mode, domain or IP address, and management port. This removes the need to manually enter controller information on every new device and is widely used in iMaster NCE- Campus onboarding workflows. Therefore, the numeric value required in the blank is 148, matching the source answer and Huawei campus deployment documentation.
