NEW QUESTION # 134
Which of the following DHCPv4 messages are sent by a DHCPv4 server?
Answer: A,B
NEW QUESTION # 135
Four links between two switches establish an Eth-Trunk in manual mode, and the bandwidth of each link is 1 Gbit/s. One of the links fails. Which of the following statements are true about this scenario? (Select all that apply)
Answer: C,D
Explanation:
In an Eth-Trunk working in manual mode, multiple physical member links are bundled into one logical interface to provide higher bandwidth and link redundancy. If one of four 1 Gbit/s member links fails, the Eth-Trunk does not go down as long as at least one valid member link remains active. Therefore, statement A is correct. Since one link has failed and three member links remain available, the total available bandwidth becomes 3 Gbit/s, so statement B is also correct.
NEW QUESTION # 136
Assume you are an administrator of a campus network. You want to enable STelnet on network devices so that you can remotely log in to them for service commissioning and configuration changes. Which of the following statements is false about STelnet?
Answer: A
NEW QUESTION # 137
On the network shown in the figure, the interfaces connecting switches to terminals are access interfaces, and the interfaces connecting switches to each other are trunk interfaces. The administrator configures interface- based VLAN assignment. PC1 and PC3 belong to VLAN 2, and PC2 and PC4 belong to VLAN 3. Trunk interfaces allow packets from VLAN 2 and VLAN 3 to pass through and use the default PVID. The MAC address tables of switches are empty. When SW1 receives a unicast data frame sent from PC1 to PC3, through which of the following interfaces does SW1 not send the data frame?
Answer: B,C
Explanation:
PC1 and PC3 are members of VLAN 2, while PC2 and PC4 are members of VLAN 3. SW1 receives the frame from PC1 on access interface GE1/0/1 and associates it with VLAN 2. Because all switch MAC address tables are initially empty, PC3 ' s destination MAC address is unknown to SW1. The switch therefore floods this unknown unicast frame only through other interfaces that can carry VLAN 2. GE1/0/3 connects to PC3 in VLAN 2, so it is a valid flood port. GE1/0/4 is a trunk that permits VLAN 2 and VLAN 3, so it is also eligible to carry the VLAN 2 frame. SW1 does not send the frame back through GE1/0/1, the ingress interface, and it does not send it through GE1/0/2 because that access port belongs to VLAN 3. Therefore, the interfaces through which SW1 does not send the frame are GE1/0/2 and GE1/0/1, corresponding to A and D.
NEW QUESTION # 138
When deploying a WLAN with the WAC + Fit AP architecture on a customer ' s live network, you find that APs fail to go online. Which of the following are possible causes? (Select all that apply)
Answer: A,B,C,D
Explanation:
Huawei ' s HCIA-Datacom WLAN training material describes several conditions necessary for successful Fit AP onboarding.
Option A is correct because APs require IP connectivity to communicate with the WAC and establish CAPWAP tunnels.
Option B is correct because Fat APs operate independently and do not use the centralized Fit AP management architecture unless their operating mode is changed.
Option C is correct because Huawei WACs require a CAPWAP source interface or source IP address for tunnel establishment.
Option D is correct because Fit APs normally require valid IP addresses before communicating with their WAC.
The DHCP configuration must therefore provide suitable IP addressing, gateway information, and any necessary WAC discovery information.
Successful AP onboarding depends on network connectivity, appropriate AP operating mode, WAC discovery, and CAPWAP tunnel establishment.
Therefore, all four options are correct.
