Huawei HCIP-Data Center Network V1.0 Sample Questions (Q32-Q37):

NEW QUESTION # 32
In the VPC interworking scenario, traffic is checked and filtered only by the firewall in the source or destination VPC.

A. FALSE
B. TRUE

Answer: A

Explanation:
In Huawei's CloudFabric Solution, Virtual Private Clouds (VPCs) enable isolated network environments, and interworking scenarios involve traffic between VPCs. The statement claims that traffic is checked and filtered only by the firewall in the source or destination VPC. Let's evaluate:
VPC Interworking: Traffic between VPCs can be routed via a gateway (e.g., a Layer 3 gateway or centralized router) and may involve multiple security checkpoints depending on the design. Firewalls can be deployed in the source VPC, destination VPC, or a centralized location (e.g., a service chain or border gateway).
Firewall Role: The statement implies exclusivity (only one firewall), but in practice, traffic may be filtered by firewalls at both ends, a centralized firewall, or additional security devices (e.g., VAS nodes) in the path. For example, inter-VPC traffic might pass through a firewall in the source VPC for egress filtering and another in the destination VPC for ingress filtering, or a shared firewall in a hub-and-spoke model. Huawei's security architecture (e.g., with SecoManager) supports distributed or centralized filtering, not limited to a single VPC's firewall.
The statement is FALSE (B) because traffic is not restricted to being checked and filtered only by the firewall in the source or destination VPC; multiple firewalls or security devices may be involved.

NEW QUESTION # 33
Which of the following are advantages of iMaster NCE-FabricInsight's telemetry-based performance metric collection? (Select All that Apply)

A. One-off subscription and continuous data push
B. Intelligent data analysis and automated troubleshooting
C. Quasi-real-time data collection
D. Efficient transmission

Answer: A,C,D

Explanation:
iMaster NCE-FabricInsight uses telemetry for performance metric collection, offering advanced monitoring in Huawei's CloudFabric Solution. Let's evaluate each option:
A . Efficient transmission: This is true. Telemetry uses streaming data (e.g., gRPC) to reduce overhead compared to traditional polling, enabling efficient transmission of metrics. TRUE.
B . Quasi-real-time data collection: This is true. Telemetry provides near-real-time data (e.g., sub-second updates), improving responsiveness over periodic SNMP polling. TRUE.
C . Intelligent data analysis and automated troubleshooting: This is false. While FabricInsight performs intelligent analysis, automated troubleshooting is a feature of the broader iMaster NCE platform, not specifically a telemetry advantage. Telemetry enables data collection, not the automation itself. FALSE.
D . One-off subscription and continuous data push: This is true. Telemetry operates on a subscription model where a one-time setup leads to continuous data push from devices, reducing manual intervention. TRUE.
Thus, A, B, and D are advantages of telemetry-based performance metric collection.

NEW QUESTION # 34
Linux consists of the user space and kernel space. Which of the following functions are included in the kernel space? (Select All that Apply)

A. The NIC driver sends data frames.
B. Data encryption
C. Bit stream transmission
D. Data encapsulation

Answer: A,C,D

Explanation:
In Linux, the operating system is divided into user space (where applications run) and kernel space (where the OS core functions execute with privileged access to hardware). Let's evaluate each function:
A . The NIC Driver Sends Data Frames: Network Interface Card (NIC) drivers operate in kernel space, managing hardware interactions like sending and receiving data frames. This is a low-level task requiring direct hardware access, handled by the kernel's network stack. Included in Kernel Space.
B . Data Encapsulation: Data encapsulation (e.g., adding headers in the TCP/IP stack) occurs in the kernel's network subsystem (e.g., via the protocol stack like IP or TCP). This process prepares packets for transmission and is a kernel-space function. Included in Kernel Space.
C . Bit Stream Transmission: This refers to the physical transmission of bits over the network, managed by the NIC hardware and its driver in kernel space. The kernel coordinates with the NIC to send bit streams, making this a kernel-space function. Included in Kernel Space.
D . Data Encryption: Encryption (e.g., via OpenSSL or application-level VPNs) typically occurs in user space, where applications or libraries handle cryptographic operations. While the kernel supports encryption (e.g., IPsec in the network stack), the actual encryption logic is often offloaded to user-space tools, not a core kernel function in standard contexts. Not Typically in Kernel Space.
Thus, A, B, and C are functions included in the kernel space, aligning with Linux architecture in Huawei's DCN context.

NEW QUESTION # 35
Assume that a VXLAN tunnel is monitored on a Huawei CE series switch and that the tunnel status is Down or the tunnel fails to be dynamically established. In this scenario, which of the following statements are true about how to check the cause of the fault? (Select All that Apply)

A. Run the display vxlan peer command to check the cause of the fault on the peer device of the tunnel.
B. Run the display vxlan troubleshooting command to check the causes of at most the latest five failures to dynamically establish a VXLAN tunnel.
C. Run the display vxlan troubleshooting command to check at most the latest five reasons why a VXLAN tunnel goes Down.
D. Run the display vxlan statistics command to check the cause of the fault.

Answer: A,B,C,D

Explanation:
On Huawei CloudEngine (CE) series switches, VXLAN tunnel monitoring and troubleshooting involve specific commands to diagnose issues such as tunnel Down status or failed dynamic establishment. Let's evaluate each option:
A . Run the display vxlan statistics command to check the cause of the fault: This command provides statistics on VXLAN tunnel traffic, including packet drops, encapsulation/decapsulation counts, and errors. It helps identify issues like misconfiguration or network congestion, making it a valid troubleshooting tool. TRUE.
B . Run the display vxlan peer command to check the cause of the fault on the peer device of the tunnel: This command displays information about VXLAN peers, including their IP addresses, VNIs, and reachability status. Checking the peer device's status can reveal connectivity or configuration mismatches, aiding fault diagnosis. TRUE.
C . Run the display vxlan troubleshooting command to check the causes of at most the latest five failures to dynamically establish a VXLAN tunnel: This command logs and displays troubleshooting details, including the latest five failure reasons for dynamic tunnel setup (e.g., BGP EVPN issues or reachability problems). This is a standard feature on Huawei CE switches. TRUE.
D . Run the display vxlan troubleshooting command to check at most the latest five reasons why a VXLAN tunnel goes Down: This command also tracks reasons for tunnel Down events (e.g., underlay failure, peer unreachability), limited to the latest five incidents. This is consistent with Huawei's troubleshooting capabilities. TRUE.
All options A, B, C, and D are true, as they represent valid commands and approaches to troubleshoot VXLAN tunnel issues on Huawei CE switches.

NEW QUESTION # 36
Which of the following protocols is used to back up session tables between the active and standby firewalls in the hot standby scenario?

A. M-LAG
B. BFD
C. VRRP
D. HRP

Answer: D

Explanation:
In a hot standby scenario, firewalls (e.g., Huawei USG series) maintain high availability by synchronizing session tables between active and standby devices to ensure seamless failover. Let's evaluate each protocol:
A . M-LAG (Multi-Chassis Link Aggregation): M-LAG is a link aggregation technology for switches, not designed for session table backup between firewalls. Incorrect.
B . VRRP (Virtual Router Redundancy Protocol): VRRP provides gateway redundancy by electing a master router, but it does not handle session table synchronization between firewalls. Incorrect.
C . BFD (Bidirectional Forwarding Detection): BFD is a fast failure detection protocol used with routing protocols, not for session table backup. Incorrect.
D . HRP (Hot Standby Redundancy Protocol): HRP is Huawei's proprietary protocol specifically designed for firewall hot standby scenarios. It synchronizes session tables, configuration data, and status information between active and standby firewalls to ensure stateful failover. Correct.
Thus, the answer is D (HRP).
