Huawei HCIA-Datacom V2.0 Sample Questions (Q41-Q46):

NEW QUESTION # 41
Unlike distance-vector routing protocols, link-state routing protocols advertise link states instead of route information. Typical link-state routing protocols include RIP, OSPF, and IS-IS.

A. TRUE
B. FALSE

Answer: B

Explanation:
Link-state routing protocols advertise link-state information rather than full routing tables or route updates. However, RIP is not a link-state protocol; it is a distance-vector protocol. Only OSPF and IS-IS are link-state protocols, so the statement is incorrect.

NEW QUESTION # 42
Which of the following statements regarding static routing and dynamic routing is incorrect?

A. The static routing can be easily configured and managed on the enterprise network.
B. Dynamic routing will use more resources than static routes.
C. The use of dynamic routing is more convenient for the administrator to manage the network following network convergence.
D. The static routing can automatically recover when a link failure is encountered.

Answer: D

Explanation:
Static routing does not automatically recover from link failures; manual reconfiguration is required if a static route path becomes invalid. Dynamic routing protocols, on the other hand, adapt automatically to network changes, adjusting routes as needed.

NEW QUESTION # 43
A micro-enterprise is deploying a WLAN, as shown in the figure. The WAC and Fit APs communicate with each other at Layer 3. SW2 functions as a DHCP server to assign IP addresses to Fit APs, with VLAN 100 as the management VLAN. The figure also shows part of the configuration on SW2. However, Fit APs fail to go online. Which of the following is the possible cause?

A. GE0/0/1 on SW2 is not configured as an access interface.
B. DHCP Option 43 is not configured on SW2. As a result, Fit APs cannot obtain the WAC ' s IP address.
C. The management VLAN is not allowed on SW2.
D. No DHCP address pool is configured on SW2. As a result, Fit APs cannot obtain IP addresses.

Answer: B

Explanation:
In Huawei WAC + Fit AP networking, APs must discover the WAC before establishing CAPWAP tunnels.
The HCIA-Datacom V2.0 training material explains that DHCP Option 43 can deliver the WAC ' s IP address to Fit APs during DHCP address assignment.
In the exhibit, SW2 has VLAN 100 configured, permits VLAN 100 through the trunk interface, and enables DHCP address allocation through VLANIF 100.
Therefore, the VLAN and DHCP interface configuration are present.
However, DHCP Option 43 is missing. Because the WAC and Fit APs communicate across Layer 3 boundaries, broadcast-based WAC discovery cannot operate across those boundaries.
Without another configured discovery method, the APs cannot discover the WAC and establish their CAPWAP connections.
Consequently, option C identifies the missing configuration.

NEW QUESTION # 44
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)

A. RS
B. NS
C. NA
D. RA

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 # 45
Assume you are an administrator of a campus network. You want to enable STelnet on network devices so that you can remotely log in to them for service commissioning and configuration changes. Which of the following statements is false about STelnet?

A. To maintain security of internal ports, the administrator can set the STelnet remote login port to any port, for example, port 1026.
B. STelnet works in the C/S architecture. The device that needs to be remotely logged in to for commissioning is the STelnet server.
C. STelnet is a secure remote login protocol based on SSH. It is a new protocol different from Telnet.
D. To modify configurations, the privilege level of the STelnet login user cannot be set to 1.

Answer: C

Explanation:
Huawei ' s HCIA-Datacom V2.0 Training Material explicitly explains that STelnet is an application operating over SSH 2.0, not an entirely new protocol. Therefore, statement B is false according to the training material.
STelnet provides encrypted remote terminal access through SSH authentication, encryption, and integrity protection.
Statement C correctly describes the client/server architecture. The administrator ' s terminal operates as the client, while the managed device functions as the STelnet server.
Statement A reflects the requirement for sufficient command privileges when modifying device configurations.
Statement D requires qualification. Huawei supports changing the SSH server listening port, and port 1026 is a possible non-default value. However, describing the configurable value as any port is too broad because allowable values are subject to platform restrictions.
The explicit source-supported false statement is B.
