NEW QUESTION # 20
When a Huawei device functions as an SSH client to log in to another network device for the first time, the ssh client first-time enable command must be run to enable the first-time login function of the SSH client.
Otherwise, the login fails.
Answer: B
Explanation:
The HCIA-Datacom V2.0 Training Material describes the configuration of Huawei devices operating as SSH clients.
For the first-time-login workflow, the command ssh client first-time enable enables the SSH client to establish its initial connection with an SSH server whose host public key has not already been trusted.
SSH provides authentication, encryption, and integrity protection to secure remote management traffic.
During initial connection establishment, the SSH client must handle the server ' s host public key to establish trust.
The first-time-login function permits this initial trust-establishment process. Without it, a connection to a server whose host key has not been provisioned may fail.
The training material explicitly includes this command in its SSH client configuration procedure.
Therefore, within the first-time-login configuration scenario described in the question, the statement is TRUE.
NEW QUESTION # 21
DAD enables a node to detect whether an IPv6 address is already in use by another node before assigning it to an interface. This ensures that duplicate unicast addresses do not exist on a network. Which of the following packets are used for DAD? (Select all that apply)
Answer: B,C
Explanation:
Duplicate Address Detection ( DAD ) is an IPv6 mechanism used to verify that a unicast address is not already in use before the address is assigned to an interface. DAD is implemented using Neighbor Solicitation (NS) and Neighbor Advertisement (NA) messages, which are part of the ICMPv6 Neighbor Discovery protocol. Therefore, options A and D are correct.
When a host wants to verify a tentative IPv6 address, it sends an NS message for that address. If another node on the link is already using that address, that node responds with an NA message, indicating the address is duplicated and cannot be assigned. If no NA is received within the required period, the host assumes the address is unique and can use it. Options B and C are incorrect because Router Solicitation (RS) and Router Advertisement (RA) are used for router discovery, prefix advertisement, and stateless address autoconfiguration, not for DAD itself. HCIA-Datacom emphasizes the distinction between Neighbor Discovery functions, including address resolution, next-hop reachability, router discovery, and duplicate address detection in IPv6 networks.
NEW QUESTION # 22
R1 has two equal-cost routes to 10.0.12.0/24 after the following commands are configured.
[R1] ip route-static 10.0.12.0 24 10.0.12.2 preference 60
[R1] ip route-static 10.0.12.0 24 10.0.21.2 preference 60
Answer: B
Explanation:
The source key marks this statement TRUE, but the topology makes that answer technically incorrect. R1 is shown with interface address 10.0.12.1/24, which automatically installs a directly connected route to 10.0.12.0
/24. On Huawei VRP, a direct route has preference 0, whereas a static route has preference 60 unless another value is configured. The two commands do configure two static routes with the same preference, and equal- preference static routes can support load balancing when they are the best routes to a destination. Here, however, both static routes are for the same prefix that R1 already owns as a connected network. The direct route has a higher priority because its preference value is smaller, so it is selected in the active IP routing table instead of the two preference-60 static routes. Therefore the assertion that R1 has two active equal-cost routes to 10.0.12.0/24 is FALSE as the question and exhibit are written. The verified answer is B, and the original source key A should be corrected.
NEW QUESTION # 23
To prevent key services from being affected due to insufficient bandwidth of an Eth-Trunk when too many links are faulty, the administrator runs the least active-linknumber 4 command on an Eth-Trunk that has eight member interfaces to set the minimum number of active links to 4. Which of the following situations will cause the Eth-Trunk interface to go Down?
Answer: A,B,C,D
Explanation:
To achieve end-to-end Layer 2 connectivity across VLAN 2, VLAN 3, and VLAN 4, the inter- switch link must properly carry multiple VLANs, and SW2 must correctly handle VLAN 4 traffic toward PC3.
On SW1, both trunk and hybrid configurations that allow VLAN 2 and VLAN 3 are valid methods to ensure tagged VLAN traffic is transmitted across the link, and PVID adjustments ensure correct handling of untagged frames where required.
On SW2, both trunk and hybrid configurations that permit VLAN 4 ensure that PC3 receives its VLAN traffic correctly. Trunk mode carries VLAN 4 transparently, while hybrid mode can deliver VLAN 4 untagged depending on PVID settings.
Since all listed configurations correctly support VLAN propagation and inter-switch VLAN handling under Huawei switching behavior, all options are valid.
NEW QUESTION # 24
Which of the following IP addresses cannot be configured for a host by default?
Answer: A
Explanation:
The address 224.0.0.1/24 cannot be configured as a normal host IP address by default because it belongs to the Class D multicast address range . IPv4 multicast addresses range from 224.0.0.0 to 239.255.255.255 and are reserved for multicast group communication rather than assignment to host interfaces as ordinary unicast addresses. Therefore, option D is correct.
The other three options are all private unicast address ranges and can be configured on hosts in private networks. 10.0.0.1/8 belongs to the 10.0.0.0/8 private range, 172.16.1.1/16 belongs to the 172.16.0.0/12 private range, and 192.168.1.1/24 belongs to the 192.168.0.0/16 private range. These are commonly used in enterprise and campus networks. HCIA-Datacom teaches that host IP address planning must distinguish between unicast, multicast, loopback, broadcast, and other special-purpose ranges. Multicast addresses identify multicast groups and are processed differently by hosts and network devices, so they are not valid default host addresses for ordinary end-to-end IP communication.
