NEW QUESTION # 70
Which of the following information is displayed when an entered command is incomplete on the Versatile Routing Platform (VRP)?
Answer: C
NEW QUESTION # 71
In an IPv6 address, two or more consecutive groups of 0s can be compressed using a double colon (::), reducing the overall length of the address. For example, 2001:DBFF:130F:0:0:0:0:130B can be compressed to
2001:DBFF:130F::130B.
Answer: B
Explanation:
IPv6 text representation permits zero compression to make long addresses easier to read and write. One or more consecutive 16-bit groups containing only zeros can be replaced by a double colon, subject to the rule that the double-colon compression is used only once in a single IPv6 address; otherwise the number of omitted groups would be ambiguous. In the address 2001:DBFF:130F:0:0:0:0:130B, four consecutive zero groups appear between 130F and 130B. Replacing that run with :: produces 2001:DBFF:130F::130B, which expands back unambiguously to the original eight groups. Leading zeros within an individual 16-bit group can also be omitted, but that is a separate abbreviation rule. The example in the question follows valid IPv6 notation and does not alter the numeric address. Consequently, the statement that the address can be compressed in the manner shown is TRUE. The correct answer is A. The compression changes only the written representation of the IPv6 address; it does not change the underlying 128-bit address value itself in any way.
NEW QUESTION # 72
Assume that the IP address of GE0/0/0 on R1 is 10.0.12.1/24. Multiple commands can be used to enable OSPF on this interface. Match the commands with their configuration views.
Answer:
Explanation:
Explanation:
ospf 1 # [R1]
area 0 # [R1-ospf-1]
network 10.0.12.1 0.0.0.0 # [R1-ospf-1-area-0.0.0.0]
ospf enable 1 area 0 # [R1-GE0/0/0]
Huawei devices support two common ways to enable OSPF on an interface.
The first method is the process-based method . In this method, you first enter system view, then enter the OSPF process view using ospf 1, so this command belongs to [R1] . After that, you enter the area view using area 0, so this command belongs to [R1-ospf-1] . Inside the area view, the command network 10.0.12.1
0.0.0.0 is used to match the interface with IP address 10.0.12.1, so it belongs to [R1-ospf-1-area-0.0.0.0] .
The second method is the interface-based method . In this method, OSPF is enabled directly under the interface using ospf enable 1 area 0, so this command belongs to [R1-GE0/0/0] .
This question tests the difference between global OSPF process configuration and direct interface OSPF enabling , both of which are standard Huawei OSPF configuration methods.
NEW QUESTION # 73
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:
An Eth-Trunk will remain down if there is a configuration inconsistency between the two ends, but it is not specifically caused by missing member interfaces on the remote device alone. Even if SW2 has not added member interfaces, the local configuration and negotiation state (such as LACP or static Eth-Trunk consistency checks) would still determine the status, and other mismatch conditions could also lead to the same symptom. Therefore, the stated cause is not the only or guaranteed reason for the Eth-Trunk being down, making the statement incorrect.
NEW QUESTION # 74
A Huawei network device functioning as an AAA server is referred to as a local AAA server.
Compared with a remote AAA server, a local AAA server reduces operation costs. However, the amount of information that can be stored on a local AAA server is limited by the hardware performance of the device.
Answer: B
Explanation:
A local AAA server runs directly on the Huawei network device, which reduces deployment and operational costs compared to a remote AAA server. However, its storage capacity and processing capability are constrained by the device hardware resources, limiting the amount of AAA information it can maintain.
