질문 # 43
In a wireless communication system, information is first converted into digital signals for easy circuit calculation and processing by the transmitter through source coding, and then converted into radio waves through channel coding and modulation. Which of the following parameters of a carrier are modified during the modulation process based on signal changes? (Select all that apply)
정답：A,C,D
설명：
During modulation, the transmitter maps digital information onto certain physical characteristics of a carrier signal so that the information can be transmitted over the air. The three classic carrier parameters that can be modified are amplitude , frequency , and phase . Therefore, options A , B , and D are correct.
Amplitude modulation changes the strength of the carrier wave. Frequency modulation changes the oscillation rate of the carrier. Phase modulation changes the phase angle of the carrier relative to a reference. Modern wireless communication systems often combine these parameters, especially amplitude and phase, in complex digital modulation schemes such as QPSK, 16-QAM, 64-QAM, or higher-order QAM used in WLAN standards. Option C , channel, is not a carrier parameter modified during modulation. A channel refers to a frequency resource or spectrum allocation used for communication, not a physical waveform characteristic being directly altered to encode bits. HCIA-Datacom introduces these basic wireless concepts to help learners understand how WLAN signals are transmitted, how data rate improvements are achieved, and why different modulation methods have different requirements for signal quality and interference resistance.
질문 # 44
The following command is configured on the VTY interfaces of R1:
[R1-ui-vty0-4] protocol inbound all
In this case, FTP, Telnet, and SSH users can all use the five VTY interfaces.
정답：B
설명：
VTY interfaces provide remote terminal sessions to the device. The command protocol inbound all allows the interactive remote-login protocols supported by that VTY implementation, notably Telnet and SSH/STelnet.
FTP is not a VTY terminal-login protocol. FTP is a file-transfer service that uses its own server/client process, TCP sessions, authentication, and file system permissions; enabling FTP service does not make an FTP user consume a VTY terminal line in the same manner as a Telnet or SSH CLI session. Therefore, even though the word all broadens the VTY ' s permitted terminal access protocols, it does not mean that FTP users log in through those five VTY interfaces. Huawei troubleshooting documentation specifically treats protocol inbound all as satisfying Telnet and SSH access requirements. The statement incorrectly groups FTP with the VTY login protocols and claims that all three types of users can use the five VTY interfaces. That conclusion is false. The verified answer is B.
질문 # 45
FILL BLANK
If a gateway router wants its connected IPv6 terminals to obtain IPv6 addresses through SLAAC, it must set the M-bit in RA messages to _______. (Enter only digits.)
정답：
설명：
0
Explanation:
For SLAAC (Stateless Address Autoconfiguration), the router advertisement message must indicate that no DHCPv6 stateful configuration is required. This is done by setting the M-bit (Managed flag) to 0, which tells hosts to configure their IPv6 addresses using SLAAC only.
질문 # 46
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)
정답：A,B,D
설명：
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.
질문 # 47
On a campus network, if two switches are directly connected through three physical links, you can configure either STP or link aggregation to improve network reliability. These two functions are mutually exclusive, meaning only one of them can be configured on a device at a time.
정답：B
설명：
STP and link aggregation are not mutually exclusive technologies. They solve different problems and can coexist on the same switch. Link aggregation combines multiple physical Ethernet links into a logical Eth- Trunk, increasing available bandwidth and providing member-link redundancy. STP or a related spanning-tree protocol prevents Layer 2 loops by calculating a loop-free active topology and can treat an Eth-Trunk as a logical interface. In a well-designed campus network, several physical links between two switches may first be aggregated into one Eth-Trunk, while STP operates over that logical link together with other Layer 2 paths.
Conversely, if separate redundant links are not aggregated, STP may block one or more paths to prevent a loop. Choosing link aggregation can use parallel member links more efficiently than allowing STP to block individual links, but enabling one function does not prohibit use of the other elsewhere on the device.
Therefore, the assertion that only STP or link aggregation can be configured on a device at one time is incorrect. The verified answer is FALSE, option B.
