NEW QUESTION # 73
A micro-enterprise is deploying a WLAN, as shown in the figure. The WAC and Fit APs communicate with each other at Layer 3. SW2 functions as a DHCP server to assign IP addresses to Fit APs, with VLAN 100 as the management VLAN. The figure also shows part of the configuration on SW2. However, Fit APs fail to go online. Which of the following is the possible cause?
Answer: D
Explanation:
In Huawei WAC + Fit AP networking, APs must discover the WAC before establishing CAPWAP tunnels.
The HCIA-Datacom V2.0 training material explains that DHCP Option 43 can deliver the WAC ' s IP address to Fit APs during DHCP address assignment.
In the exhibit, SW2 has VLAN 100 configured, permits VLAN 100 through the trunk interface, and enables DHCP address allocation through VLANIF 100.
Therefore, the VLAN and DHCP interface configuration are present.
However, DHCP Option 43 is missing. Because the WAC and Fit APs communicate across Layer 3 boundaries, broadcast-based WAC discovery cannot operate across those boundaries.
Without another configured discovery method, the APs cannot discover the WAC and establish their CAPWAP connections.
Consequently, option C identifies the missing configuration.
NEW QUESTION # 74
After checking the status of GE0/0/1 on R1, you obtain the command output shown below. Which of the following statements are true? (Choose all that apply.)
Answer: A,C,D
Explanation:
The interface status shows both the physical layer and line protocol are UP, confirming the physical status is UP. The output explicitly indicates PVID: 1, so the VLAN ID is 1. The hardware address field displays b0c7-8733-d65c, which is the MAC address of the interface. The port mode is COMMON COPPER, meaning it is a copper Ethernet interface rather than an optical interface, so the statement about optical type is incorrect.
NEW QUESTION # 75
R1 has two equal-cost routes to 10.0.12.0/24 after the following commands are configured.
[R1] ip route-static 10.0.12.0 24 10.0.12.2 preference 60
[R1] ip route-static 10.0.12.0 24 10.0.21.2 preference 60
Answer: B
Explanation:
The source key marks this statement TRUE, but the topology makes that answer technically incorrect. R1 is shown with interface address 10.0.12.1/24, which automatically installs a directly connected route to 10.0.12.0
/24. On Huawei VRP, a direct route has preference 0, whereas a static route has preference 60 unless another value is configured. The two commands do configure two static routes with the same preference, and equal- preference static routes can support load balancing when they are the best routes to a destination. Here, however, both static routes are for the same prefix that R1 already owns as a connected network. The direct route has a higher priority because its preference value is smaller, so it is selected in the active IP routing table instead of the two preference-60 static routes. Therefore the assertion that R1 has two active equal-cost routes to 10.0.12.0/24 is FALSE as the question and exhibit are written. The verified answer is B, and the original source key A should be corrected.
NEW QUESTION # 76
The rules in an ACL may overlap. If packets match the rules with loose conditions, the later ACL rules are not processed. In this case, packets cannot match the rules with strict conditions.
Therefore, the rules with strict conditions must be arranged in front lines and those with loose conditions must be arranged towards the end.
Answer: A
Explanation:
Access Control Lists (ACLs) are processed in sequential order, meaning that once a packet matches a rule, subsequent rules are ignored. To ensure that more specific (strict) conditions are applied, strict rules should be listed first, followed by loose rules.
NEW QUESTION # 77
Which of the following IP addresses cannot be configured for a host by default?
Answer: B
Explanation:
The address 224.0.0.1/24 cannot be configured as a normal host IP address by default because it belongs to the Class D multicast address range . IPv4 multicast addresses range from 224.0.0.0 to 239.255.255.255 and are reserved for multicast group communication rather than assignment to host interfaces as ordinary unicast addresses. Therefore, option D is correct.
The other three options are all private unicast address ranges and can be configured on hosts in private networks. 10.0.0.1/8 belongs to the 10.0.0.0/8 private range, 172.16.1.1/16 belongs to the 172.16.0.0/12 private range, and 192.168.1.1/24 belongs to the 192.168.0.0/16 private range. These are commonly used in enterprise and campus networks. HCIA-Datacom teaches that host IP address planning must distinguish between unicast, multicast, loopback, broadcast, and other special-purpose ranges. Multicast addresses identify multicast groups and are processed differently by hosts and network devices, so they are not valid default host addresses for ordinary end-to-end IP communication.
