NEW QUESTION # 95
After the root bridge is elected on an STP network, which of the following parameters may be compared by ports on non-root bridge nodes to elect the root port? (Select all that apply)
Answer: A,B,C,D
Explanation:
On a non-root bridge, the root port is the port that receives the best BPDU toward the root bridge.
STP selects the root port by comparing several parameters in order. The first important parameter is the root path cost (RPC), so option B is correct. If multiple ports have the same RPC, the switch then compares the bridge ID (BID) of the upstream device sending the BPDU, making option C correct. If those are still equal, the switch compares the port ID (PID) of the upstream sending port, so option D is also correct.
If all of those values remain identical from the switch's perspective, the device can finally compare the local port ID to determine which local interface becomes the root port, so option A is also correct. HCIA-Datacom teaches this comparison logic as part of STP election rules. The process ensures deterministic selection of a single root port on every non-root switch.
Understanding the comparison sequence is essential for predicting STP topology behavior and for influencing port roles through path cost tuning or bridge-priority adjustments during campus network design and troubleshooting.
NEW QUESTION # 96
PC1 at 192.168.1.1/24 and PC2 at 192.168.1.102/25 are directly connected using an Ethernet cable, and the physical status of their network ports are normal. They can directly communicate with each other although their masks are different.
Answer: A
Explanation:
Although the two PCs are physically connected and the link status is normal, IP communication requires both devices to be in the same logical subnet to communicate directly without a router.
PC1 uses 192.168.1.1/24, while PC2 uses 192.168.1.102/25, which places them in different subnet boundaries. Because their subnet masks differ, they are not in the same Layer 3 network, so direct communication is not guaranteed and generally not possible without routing or special configuration.
NEW QUESTION # 97
Which of the following statements are true about the Python code shown below? (Select all that apply) import paramiko import time ssh = paramiko.SSHClient() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh.connect('192.168.1.254', username='python', password='Huawei@123') channel = ssh.invoke_shell() channel.send('screen-length 0 temporary\n') time.sleep(1) output = channel.recv(65535).decode('utf-8') print(output) ssh.close()
Answer: A,B,C,D
Explanation:
All four statements are correct. The code uses the Paramiko library to automate SSH login to a network device. import paramiko and import time load the Python modules required for SSH communication and delay control, so option C is correct. The statement ssh = paramiko.SSHClient() creates an SSH client object, and ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) allows the client to accept an unknown host key automatically in this example scenario.
The command ssh.connect('192.168.1.254', username='python', password='Huawei@123') establishes an SSH connection to the target device, so option B is correct. Then channel = ssh.invoke_shell() opens an interactive shell channel, which is commonly used to send CLI commands and receive output just as an administrator would in a terminal session, making option D correct. The command channel.send('screen-length 0 temporary\n') disables page-by-page output for the current session, which is useful in network automation. Finally, ssh.close() closes the SSH session and releases the connection, so option A is correct. HCIA-Datacom automation knowledge often uses Paramiko examples to demonstrate basic Python-based device O&M.
NEW QUESTION # 98
Drag and Drop Question
On the campus network shown in the figure below, the core switch Core1 functions as a Layer 3 gateway and as a DHCP server to dynamically assign IP addresses to AP1, PC1, PC2, and PC3.
The network below Core1 is a Layer 2 network. WAC1 and R1 are connected to Core1 at Layer
3. AP1 goes online through VLAN 100. VLAN 101 and VLAN 102 are respectively used for the wireless and wired services. Additionally, the tunnel forwarding mode is used for wireless traffic forwarding. Match device interfaces with their respective allowed VLANs. (Note: No additional VLANs are allowed on device interfaces, and interconnection VLANs are not considered.)
Answer:
Explanation:
Explanation:
VLAN 100 -> GE1/0/3 of ACC1
VLAN 101-> GE1/0/2 of Core1
VLAN 102 -> GE1/0/1 of ACC2
VLAN 100 and VLAN 101 -> GE1/0/1 of ACC1
VLAN 100 and VLAN 101 -> GE1/0/3 of Core1
VLAN 102 -> GE1/0/4 of Core1
GE1/0/3 of ACC1 -> VLAN 100: This interface directly connects ACC1 to AP1. Since AP1 goes online through management VLAN 100 and wireless user traffic uses tunnel forwarding mode (where user data is encapsulated inside a CAPWAP tunnel directly to WAC1), the physical link to the AP only needs to pass the untagged management traffic of VLAN 100.
GE1/0/2 of Corel -> VLAN 101: This port links Corel to WAC1. In tunnel forwarding mode, all wireless user data (VLAN 101) is encapsulated inside CAPWAP data tunnels by the AP and sent to the WAC. The WAC then decapsulates this traffic and forwards it into the core switch.
Therefore, the interface facing WAC1 must allow service VLAN 101 to route the decapsulated wireless traffic.
GE1/0/1 of ACC2 -> VLAN 102: This interface forms the uplink from the access switch ACC2 to Corel. Because ACC2 only services PC3 (wired service VLAN 102), its uplink only requires access to VLAN 102.
GE1/0/1 of ACC1 -> VLAN 100 and VLAN 102: This is the uplink interface from ACC1 to Corel.
ACC1 hosts AP1 (which requires management VLAN 100) and PC2 (which belongs to wired service VLAN 102). Therefore, this trunk link must allow both VLAN 100 and VLAN 102.
GE1/0/3 of Corel -> VLAN 100 and VLAN 102: This interface connects Corel down to ACC1. To match the configuration of ACCTs uplink, it must allow both the AP management traffic (VLAN
100) and the local wired user traffic (VLAN 102).
GE1/0/4 of Corel -> VLAN 102: This port connects Corel to ACC2. Because ACC2 exclusively handles the wired clients residing in service VLAN 102, this downlink interface only needs to permit VLAN 102.
NEW QUESTION # 99
With the continuous development of AI, data center application scenarios are gradually divided into general- purpose computing and intelligent computing scenarios. Data centers need to ensure service continuity of general-purpose computing clusters while unleashing the full potential of intelligent computing clusters, so as to guarantee stable and efficient operation in the AI era. Which of the following statements are true about the service requirements of data center networks in the two scenarios? (Select all that apply)
Answer: C,D
Explanation:
The correct statements are B and C . Option B is true because general-purpose computing data center networks focus heavily on stability, reliability, service continuity, and flexible VM deployment. Technologies such as M-LAG improve gateway and uplink redundancy and support fast failover, while VXLAN enables large-scale Layer 2 extension for VM mobility and resource flexibility.
Option C is also true because intelligent computing networks, especially those serving AI training and distributed GPU clusters, require an extremely low-loss or lossless forwarding environment. Technologies such as PFC and ECN are standard methods used to build such networks and reduce congestion-related packet loss. Option A is not selected because modern general-purpose data center networks do not necessarily require the traditional core-aggregation-access three-layer architecture ; contemporary data centers commonly use leaf-spine fabrics instead. Option D is not selected because although intelligent computing networks do require ultra-low latency and RoCE helps reduce network communication latency, the wording about "latency of data transmission within a compute node" is not the standard network-side requirement emphasized in HCIA-Datacom. The focus is mainly on inter-node network transport efficiency and lossless forwarding.
