NEW QUESTION # 138
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 PC2 successfully pings the IP address of PC1. 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 connects GE1/0/1 of SW1 to another switch. Then, the administrator pings the IP address of PC1 from PC2. In this case, SW1 discards the data frame received from PC2.
Answer: B
Explanation:
Before PC1 is moved, PC2 successfully communicates with it, so SW1 learns PC1 ' s MAC address on GE1/0
/1. The dynamic MAC aging time is 300 seconds, and the cable move is performed immediately. Therefore, when PC2 sends the next frame to PC1, SW1 can still have the old destination MAC entry pointing to GE1/0
/1. The question then states that GE1/0/1 is connected to another switch, so the port remains physically usable.
SW1 follows the existing MAC table entry and forwards the frame out GE1/0/1 toward that new connection; it does not simply discard the frame. If PC1 subsequently transmits from GE1/0/2, SW1 can relearn the same source MAC on the new interface and update the entry, restoring correct forwarding. The core point is that dynamic MAC entries do not immediately disappear merely because the end station is physically moved when the original interface remains Up. Accordingly, the statement that SW1 discards the frame is FALSE, option B.
NEW QUESTION # 139
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.
Answer: B
Explanation:
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.
NEW QUESTION # 140
The figure below shows the partial topology of a campus network and the corresponding data plan. The interconnected physical interfaces only allow traffic from the interconnection VLAN, and the corresponding VLANIF interfaces have been created. Across the entire campus network, OSPF is deployed to implement Layer 3 connectivity, and STP is enabled. Given this, which of the following statements are true?
Answer: C,D
Explanation:
The topology contains three Layer 3 interconnection VLANs: VLAN 12 between Core1 and ACC1, VLAN
13 between Core1 and ACC2, and VLAN 23 between ACC1 and ACC2. OSPF is enabled across the campus, while STP still controls Layer 2 forwarding on the VLAN links. If ACC2 GE1/0/3 is an alternate port, STP blocks service forwarding on the ACC1-ACC2 path. As a result, OSPF Hello packets cannot be exchanged across that blocked Layer 2 path and ACC1 and ACC2 cannot establish an OSPF neighbor relationship on VLAN 23, so C is true. Core1 still has routes for all three interconnection networks: VLAN 12 and VLAN 13 are directly connected, and information for VLAN 23 can be learned through OSPF from the access devices, making B true. Statement A is incorrect because ACC1 already has VLANIF 23 as a directly connected network rather than needing to learn that same connected segment through OSPF. Statement D is also false:
STP can still be relevant on Layer 2 VLAN links even in a campus using Layer 3 routing.
NEW QUESTION # 141
FTP allows users to remotely log in to a network device to manage configuration files (such as uploading and downloading files) and modify configurations (such as renaming the device and configuring an IP address).
Answer: B
Explanation:
FTP (File Transfer Protocol) is primarily designed to transfer files between a client and server. It allows administrators to upload, download, and manage files stored on Huawei network devices.
However, FTP does not provide an interactive command-line environment for directly modifying device configurations. Tasks such as changing the system name or configuring interface IP addresses require access to the device ' s CLI through an appropriate management connection.
Huawei devices support STelnet, which uses SSH to establish secure remote terminal sessions. Administrators can execute authorized configuration commands through these sessions.
Although FTP can transfer configuration files to a device, transferring files is different from executing configuration commands.
Therefore, the statement incorrectly combines FTP file-management capabilities with interactive device configuration. The correct answer is FALSE.
NEW QUESTION # 142
Which of the following information is displayed when an entered command is incomplete on the Versatile Routing Platform (VRP)?
Answer: B
Explanation:
When a command entered on Huawei's Versatile Routing Platform (VRP) is incomplete, VRP generates an error message indicating that the command is incomplete at a specific position (designated by 'A'). This message helps administrators identify where additional parameters are needed to complete the command syntax. Other error messages indicate issues such as excess parameters or ambiguous commands.
