질문 # 23
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. NA
B. RS
C. RA
D. NS

정답：A,D

설명：
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.

질문 # 24
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?

A. The user cannot obtain authorization information after being authenticated because the IP address of the authorization server is not configured in the RADIUS server template.
B. When a terminal initiates an authentication request, R1 needs to first establish a TCP connection with the server whose IP address is 10.1.6.6.
C. RADIUS does not support accounting. Even if an accounting server is specified in the RADIUS server template, accounting cannot be performed when terminals access the network.
D. When a terminal uses the user name hcia-datacom@huawei.com to initiate authentication, RADIUS authentication is used.

정답：D

설명：
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.

질문 # 25
On an intelligent computing data center network, network administrators deploy various intelligent lossless network technologies such as PFC to implement a high-speed and low-latency lossless network. Which of the following statements are false about the working principles of PFC?
(Choose all that apply.)

A. After backpressure is triggered, the receive end sends PFC stop packets to the transmit end only after the buffer of the receive end is cleared.
B. After PFC is deployed, the receive end sends PFC packets to the transmit end when the received traffic exceeds a certain buffer threshold, requesting the transmit end to reduce the packet sending rate.
C. After backpressure is triggered, the receive end sends PFC stop packets to the transmit end as long as the buffer of the receive end decreases to a certain extent.
D. After PFC is deployed, the receive end sends PFC packets to the transmit end when the buffer is full, requesting the transmit end to reduce the packet sending rate.

정답：A,C

설명：
PFC (Priority Flow Control) is triggered before buffer overflow, based on predefined thresholds, not only when the buffer is fully cleared. The receiver sends PFC pause frames when congestion is detected or thresholds are exceeded to pause specific traffic priorities. It resumes transmission by sending a PFC resume (stop pause) frame once congestion is relieved to a safe threshold level, not after the buffer is completely emptied.

질문 # 26
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. FALSE
B. TRUE

정답：A

설명：
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.

질문 # 27
In the STP topology shown in the figure, all links have the same path cost, and SW1 is the root bridge. Which of the following ports will become designated ports? (Select all that apply)

A. GE1/0/3 of SW3
B. GE1/0/1 of SW2
C. GE1/0/1 of SW4
D. GE1/0/2 of SW2

정답：A,B,D

설명：
In STP, the root bridge has all its active ports elected as designated ports on each connected segment. On non-root switches, one port is selected as the root port, and on each LAN segment, one designated port is elected based on the best BPDU. Since SW1 is the root bridge and all links have equal cost, the election depends first on the path cost to the root, then on bridge ID, and then on port ID if needed.
According to the topology, the ports that become designated are GE1/0/2 of SW2, GE1/0/1 of SW2, and GE1/0/3 of SW3, which correspond to option A, B, and C.
