질문 # 44
On the network shown in the figure, it is required that interfaces on R1 and R3 are reachable to each other through static routes. When implementing this requirement, there is no need to configure static routes on
_____. (Enter a device name in the figure, for example, R1.)
정답：
설명：
R2
Explanation:
A directly connected route is automatically generated when a router interface has a valid IP address and the interface is operational.
In this topology, R2 connects directly to two networks: 10.0.0.0/24 through GE0/0/1 and 20.1.1.0/24 through S1/0/0.
Therefore, R2 already has the necessary routing information to forward packets between these two directly connected networks. Additional static routes are not required on R2.
However, R1 initially knows only its directly connected network, so it requires a static route toward 20.1.1.0
/24 using R2 as its next hop.
Similarly, R3 requires a static route toward 10.0.0.0/24 through R2.
These routes provide bidirectional connectivity between interfaces on R1 and R3.
Therefore, the router that does not require additional static routes is R2.
질문 # 45
On the switched network shown in the figure, STP is enabled on all devices. SW1 is the root bridge. The port costs are shown in the figure. Other parameters retain the default values. After the network is stable, which of the following paths is used by SW1 to send traffic to SW4?
정답：D
설명：
After STP convergence, only ports in the forwarding state participate in active traffic forwarding, while redundant ports may be placed into the blocking or discarding state to eliminate loops.
According to the topology and STP role election shown in the question, the valid forwarding path from SW1 to SW4 is SW1 -> SW3 -> SW4, so option B is correct.
질문 # 46
On the network shown in the figure, R1 serves as the gateway for PC2 and PC3, and directly connects to S1 through a physical link. GE1/0/1 on S1 is configured as a trunk interface and permits traffic of VLANs 2 and
3. Its PVID retains the default value. Which of the following statements are true if PC2 and PC3 can communicate with each other? (Select all that apply)
정답：A,B,C
설명：
This scenario describes the classic router-on-a-stick inter-VLAN routing design. A single physical interface on R1 connects to switch S1, and multiple sub-interfaces are created on that physical interface to serve as gateways for multiple VLANs. Therefore, if R1 provides Layer 3 gateway functions for VLAN 2 and VLAN
3, sub-interfaces such as GE0/0/1.2 and GE0/0/1.3 must be configured, so option A is correct.
Because PC2 and PC3 are connected to switch S1, S1 learns their source MAC addresses dynamically and stores them in its MAC address table, making option B correct. R1 receives tagged frames from different VLANs on the trunk link and, through its sub-interfaces, can identify and terminate frames for VLAN 2 and VLAN 3, so option C is also correct. Option D is incorrect because hosts in different VLANs do not need to be connected to different physical switches; VLAN separation is logical, not necessarily physical. HCIA- Datacom uses this deployment to explain inter-VLAN communication, 802.1Q trunking, and flexible campus gateway design using limited router interfaces.
질문 # 47
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：B,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 # 48
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.)
정답：A,B
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.
