NEW QUESTION # 75
R1 has the following configurations:
[R1] radius-server template 1
[R1-radius-1] radius-server authentication 10.1.6.6 1812
[R1-radius-1] radius-server accounting 10.1.6.6 1813
[R1-radius-1] radius-server shared-key cipher YsHsjx_202206139
[R1-radius-1] quit
[R1] aaa
[R1-aaa] authentication-scheme auth1
[R1-aaa-authen-auth1] authentication-mode radius
[R1-aaa-authen-auth1] quit
[R1-aaa] accounting-scheme acc1
[R1-aaa-accounting-acc1] accounting-mode radius
[R1-aaa-accounting-acc1] quit
[R1-aaa] domain huawei.com
[R1-aaa-domain-huawei.com] authentication-scheme auth1
[R1-aaa-domain-huawei.com] accounting-scheme acc1
[R1-aaa-domain-huawei.com] radius-server 1
[R1-aaa-domain-huawei.com] quit
[R1-aaa] quit
Which of the following statements is true?
Answer: A
Explanation:
Option D is correct. The AAA configuration binds the domain huawei.com to the authentication scheme auth1 , which uses RADIUS as the authentication mode, and to the accounting scheme acc1 , which also uses RADIUS. Therefore, when a user logs in with a user name in the format hcia-datacom@huawei.com , the device parses the suffix @huawei.com, matches the domain, and applies the configured RADIUS authentication method.
Option A is false because RADIUS does support accounting , and UDP port 1813 is commonly used for that purpose. Option B is false because a separate authorization server IP is not strictly required in this context; RADIUS can carry authorization attributes together with authentication/accounting processing depending on server behavior and device configuration. Option C is false because standard RADIUS communication uses UDP , not TCP, with authentication typically on port 1812 and accounting on 1813 . HCIA-Datacom teaches domain-based AAA processing as a key concept, where the user name suffix determines which authentication, authorization, and accounting policies are applied on the NAS device.
NEW QUESTION # 76
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.
NEW QUESTION # 77
In the figure, a web client sends an HTTP request to a web server, and the router in between performs operations on the HTTP request. Which of the following statements are false about the router's operations?
(Select all that apply)
Answer: A,B,C
Explanation:
A router works mainly at the network layer. When it receives a frame, it removes the Layer 2 header and trailer, examines the destination IP address in the Layer 3 header, consults the routing table, selects the outgoing interface, and then re-encapsulates the packet into a new Layer 2 frame for the next hop. Therefore, statement B is true and is not part of the answer.
Statement A is false because the router does not create a new destination IP address during normal forwarding. The source and destination IP addresses remain unchanged end to end unless special functions such as NAT are used. Statement C is false because routing-table lookup is based on the destination IP address, not on TCP or UDP port numbers. Statement D is also false because normal IP routing does not inspect application-layer content to determine the outgoing interface. That decision is made from the network- layer destination address and the routing table. This question tests the layered forwarding logic of routers in TCP/IP networks.
NEW QUESTION # 78
The administrator configures an Eth-Trunk in LACP mode between two switches, and sets the maximum number of active links in the Eth-Trunk to 3 and the number of remaining standby links to 1. If one of the active links fails, the two switches automatically adjust the number of active links to 2 through negotiation, and the standby link remains in the standby state.
Answer: A
Explanation:
This statement is false . In an Eth-Trunk operating in LACP mode , if the administrator sets the maximum number of active links to 3 and there is 1 standby link, then when one active member fails, LACP can automatically promote the standby member to active status. The purpose of the standby member is to maintain the configured active-link capacity whenever possible.
Therefore, after one active link fails, the normal expectation is not that the active-link count is reduced from 3 to 2 while the standby link remains idle. Instead, the standby link should participate and replace the failed member, so that the Eth-Trunk continues operating with 3 active links if the standby link and negotiation conditions are normal. This reflects the redundancy and fast recovery capabilities of LACP-based aggregation. HCIA-Datacom highlights that compared with manual mode, LACP provides more intelligent link selection, active/standby management, and fault adaptation. The statement is wrong because it ignores the intended behavior of the standby link in maintaining the number of active forwarding links after a failure.
NEW QUESTION # 79
Which of the following are features of the OSPF protocol?
Answer: B,C
Explanation:
Option B: OSPF supports triggered updates, allowing routing tables to be updated only when changes occur, conserving bandwidth.
Option D: OSPF supports area division, which is essential for optimizing large networks and limiting the scope of link-state advertisements.
