質問 # 173
With the development of data centers, a large number of services are deployed on virtual machines (VMs). The original VLAN isolation solution cannot achieve isolation between so many VMs. VXLAN uses VXLAN Network Identifiers (VNIs) to provide a larger range than VLAN IDs, so that a larger number of VMs can be isolated.
正解：A
解説：
This statement is true. Traditional VLANs use a 12-bit VLAN ID, which means that only about
4094 usable VLANs are available. In modern data centers, especially in cloud and virtualization environments, that scale is often insufficient because a very large number of tenants, services, and virtual machines need isolated network segments.
VXLAN addresses this limitation by introducing the VNI (VXLAN Network Identifier), which is 24 bits long. This allows support for up to about 16 million logical segments, greatly expanding the number of isolated Layer 2 networks that can be created across an IP underlay. Because of this, VXLAN is widely used in modern data centers to provide scalable tenant isolation, flexible service deployment, and large Layer 2 extension across physical boundaries. HCIA-Datacom highlights VXLAN as a key overlay technology that solves the VLAN scale problem in virtualized data center environments. It allows a much larger number of VMs and tenants to be isolated than traditional VLAN-based solutions can support, making it essential for modern cloud-oriented and large-scale data center networking.

Which of the following IP addresses cannot be configured for a host by default?
正解：D
解説：
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.
質問 # 175
Both SNMP Trap and Inform Request are used by managed devices to send alarms to the NMS. Inform Request requires an acknowledgment from the NMS, whereas Trap does not.
正解：A
解説：
This statement is true . In SNMP, both Trap and Inform messages are used by managed devices to proactively report alarms or events to the Network Management System (NMS) . However, their reliability behavior is different. A Trap is sent without requiring an acknowledgment from the NMS. Once it is transmitted, the sender does not confirm whether the manager actually received it.
By contrast, an Inform Request requires the NMS to send a response confirming receipt. If the managed device does not receive the acknowledgment within the expected time, it can retransmit the Inform message.
Because of this, Inform is considered more reliable than Trap, although it also introduces slightly more overhead. HCIA-Datacom highlights this difference when explaining SNMP-based monitoring and alarm reporting. In real network O & M scenarios, the choice between Trap and Inform depends on the required balance between reliability and simplicity. This question tests a very standard SNMP knowledge point: Trap is unacknowledged , while Inform is acknowledged . Understanding this distinction helps network engineers choose suitable alarm reporting mechanisms in enterprise monitoring platforms.
質問 # 176
Which of the following hosts are reachable to the host at 192.168.1.200/27 at Layer 2? (Select all that apply)
正解：A、B、D
解説：
A /27 subnet mask is 255.255.255.224, which means each subnet contains 32 IP addresses. The subnet increments in blocks of 32 in the last octet: 0, 32, 64, 96, 128, 160, 192, 224. The address 192.168.1.200/27 belongs to the subnet 192.168.1.192/27.
For this subnet, the network address is 192.168.1.192, the broadcast address is 192.168.1.223, and the valid host range is from 192.168.1.193 to 192.168.1.222. Therefore, 192.168.1.221/27, 192.168.1.193/27, and
192.168.1.222/27 are all valid host addresses in the same subnet and are reachable at Layer 2 without routing.
That makes A, C, and D correct.
Option B is not correct because 192.168.1.192/27 is the network address of the subnet and cannot be assigned to a host by default. This question checks IP subnetting and the ability to identify valid hosts within the same broadcast domain.

The following command output is displayed on R1:
[R1] display aaa configuration
Domain Name Delimiter : @
Domainname parse direction : Left to right
Domainname location : After-delimiter
Administrator user default domain : default_admin
Normal user default domain : default
Domain : total: 256 used: 3
Authentication-scheme : total: 32 used: 2
Accounting-scheme : total: 32 used: 1
Authorization-scheme : total: 32 used: 2
Service-scheme : total: 256 used: 0
Recording-scheme : total: 32 used: 0
Local-user : total: 512 used: 2
Remote-admin-user block retry-interval : 5 Min(s)
Remote-admin-user block retry-time : 3
Remote-admin-user block time : 5 Min(s)
Session timeout invalid enable : No
Which of the following statements is false?
正解：A
解説：
The false statement is B. From the AAA configuration output, the value of Remote-admin-user block time is clearly shown as 5 Min(s), which means the account lockout duration is 5 minutes, not 30 minutes.
