NEW QUESTION # 115
In the WAC + Fit AP networking, the WAC centrally manages and controls APs through _____ tunnels.
(Enter the acronym in uppercase.)
Answer:
Explanation:
CAPWAP
Explanation:
CAPWAP stands for Control And Provisioning of Wireless Access Points.
The HCIA-Datacom V2.0 Training Material explains that Huawei WAC + Fit AP networking uses CAPWAP tunnels to establish communication between wireless access controllers and Fit APs.
A WAC centrally manages and configures APs, reducing the need to configure individual APs separately.
CAPWAP supports control tunnels and data tunnels.
Control tunnels transmit management and control information, including configuration delivery, AP status management, and other control messages.
Data tunnels can transport wireless user traffic when tunnel forwarding is enabled.
CAPWAP also supports Datagram Transport Layer Security (DTLS), improving the security of communication between the WAC and APs.
This architecture is widely used in enterprise WLAN deployments that require centralized management.
Therefore, the required acronym is CAPWAP.
NEW QUESTION # 116
If host A wants to communicate with host B, which is on another subnet, host A broadcasts an ARP request to obtain host B ' s MAC address. After receiving the request, host B replies with an ARP response to notify host A of its MAC address.
Answer: A
Explanation:
ARP resolves an IPv4 address to a Layer 2 MAC address only within the local broadcast domain. When Host A determines, from its IP address and subnet mask, that Host B is on a different subnet, Host A does not broadcast an ARP request for Host B ' s MAC address. Instead, it forwards the packet to its default gateway.
If the gateway ' s MAC address is not already cached, Host A broadcasts an ARP request for the gateway interface ' s IPv4 address. The gateway replies with its own MAC address, and Host A uses that MAC address as the Ethernet destination while retaining Host B ' s IP address as the IP destination. The router then forwards the packet toward Host B and may perform ARP on the destination subnet to learn Host B ' s MAC address.
Therefore, the statement incorrectly describes cross-subnet forwarding as direct ARP resolution between the two hosts. The correct answer is FALSE, option B.
NEW QUESTION # 117
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.)
Answer:
Explanation:
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.
NEW QUESTION # 118
When a Huawei network device functions as an FTP server, which of the following are possible causes of an FTP client failing to log in to the FTP server? (Select all that apply)
Answer: A,B,C,D
Explanation:
All four options are possible causes of FTP login failure, so the correct answer is A, B, C, and D.
Option A is correct because if the FTP server function is not enabled on the Huawei device, the device cannot provide FTP services and the client cannot log in. Option B is also correct because if the authorized directory is not specified for the FTP user, the user may not be able to complete login or access file services properly, depending on the FTP user configuration requirements.
Option C is correct because an FTP user account must be configured with the required username and password; otherwise, authentication cannot succeed. Option D is also correct because if the network between the FTP client and the device is unreachable, the client cannot establish the FTP connection at all.
In HCIA-Datacom troubleshooting, FTP login failure is usually checked from four aspects: service enablement, user configuration, permission or directory authorization, and network connectivity.
This question tests standard remote maintenance troubleshooting logic for file transfer services on Huawei network devices.
NEW QUESTION # 119
The figure shows the simplified topology of an enterprise campus network. On this network, the aging time of dynamic MAC address entries on switches is 300 seconds.
The administrator connects PC1 to GE1/0/1 of SW1 and successfully pings the IP address of PC2 from PC1.
Then, the administrator disconnects the Ethernet cable of PC1
from GE1/0/1 of SW1, immediately connects the cable to GE1/0/2 of SW1, and pings the IP address of PC2 from PC1. Which of the following operations does SW1 perform after receiving a data frame from PC1 when PC1 is connected to GE1/0/2 of SW1?
Answer: C
Explanation:
An Ethernet switch learns MAC address entries dynamically by examining the source MAC address of incoming frames. When SW1 first receives frames from PC1 on GE1/0/1, it creates a MAC address table entry mapping PC1's MAC address to that port. If PC1 later sends frames that arrive on GE1/0/2, SW1 updates the learned entry to reflect the new incoming interface. Therefore, option B is correct: SW1 saves the mapping between PC1's MAC address and GE1/0/2 and removes or overwrites the old mapping associated with GE1/0/1.
Option A is incorrect because a single dynamic MAC address is not normally maintained on two different ports within the same VLAN at the same time; that would cause forwarding ambiguity. Option C is incorrect because a normal move of one MAC address does not require clearing the entire MAC table. Option D is also incorrect because switches update MAC learning dynamically upon receiving new source traffic and do not have to wait for the previous entry to age out. HCIA-Datacom uses this principle to explain MAC address learning, migration, and troubleshooting of loops or host movement in switched Ethernet networks.
