질문 # 53
Which of the following statements are false about heartbeat link faults in an M-LAG? (Select All that Apply)
정답:A,D
설명:
In Huawei's M-LAG (Multi-Chassis Link Aggregation), the heartbeat link (or peer-link) ensures communication between member devices. A fault in this link can impact M-LAG operation. Let's evaluate each statement:
A . The fault that two master devices exist cannot be detected in the case of a peer-link fault: This is false. A peer-link fault can be detected, and mechanisms like dual-master detection (e.g., via Inter-Chassis Communication Link or ICC) can identify if both devices assume master roles, triggering corrective actions. FALSE.
B . An alarm is triggered: This is true. A peer-link fault generates an alarm to notify administrators, as it's a critical failure in M-LAG operation, per Huawei's fault management system. TRUE.
C . The fault protection mechanism is triggered: This is true. Huawei M-LAG includes protection mechanisms (e.g., failover to backup links or shutdown of conflicting interfaces) to mitigate peer-link faults and maintain service continuity. TRUE.
D . Services are affected: This is false. With proper configuration (e.g., redundant links or fast failover), services should not be affected by a peer-link fault, as M-LAG is designed for high availability. Impact depends on redundancy, but the design goal is uninterrupted service. FALSE.
Thus, A and D are false statements because dual-master faults can be detected, and services are not necessarily affected with adequate redundancy.
질문 # 54
Which of the following is not an advantage of link aggregation on CE series switches?
정답:A
설명:
Link aggregation, often implemented using Link Aggregation Control Protocol (LACP) on Huawei CloudEngine (CE) series switches, combines multiple physical links into a single logical link to enhance network performance and resilience. The primary advantages include:
Load Balancing Supported (B): Link aggregation distributes traffic across multiple links based on hashing algorithms (e.g., source/destination IP or MAC), improving load distribution and preventing any single link from becoming a bottleneck.
Increased Bandwidth (C): By aggregating multiple links (e.g., 1 Gbps ports into a 4 Gbps logical link), the total available bandwidth increases proportionally to the number of links.
Improved Reliability (D): If one link fails, traffic is automatically redistributed to the remaining links, ensuring continuous connectivity and high availability.
However, Improved Forwarding Performance of Switches (A) is not a direct advantage.
Forwarding performance relates to the switch's internal packet processing capabilities (e.g., ASIC performance, forwarding table size), which link aggregation does not inherently enhance. While it optimizes link utilization, it doesn't improve the switch's intrinsic forwarding rate or reduce latency at the hardware level. This aligns with Huawei's CE series switch documentation, where link aggregation is described as enhancing bandwidth and reliability, not the switch's core forwarding engine.
질문 # 55
An enterprise builds a DC and deploys iMaster NCE-Fabric to automatically deliver network configurations. After the engineer manually deploys the underlay network and delivers overlay network configurations through iMaster NCE-Fabric, it is found that tenant hosts cannot access external networks. Which of the following is not a possible cause of this fault?
정답:C
설명:
In Huawei's CloudFabric Solution, iMaster NCE-Fabric automates overlay network (e.g., VXLAN) configuration, while the underlay network is manually deployed. Tenant hosts failing to access external networks indicate a connectivity issue, likely at the overlay-underlay boundary or security layer. Let's evaluate each option as a possible cause:
A . No return route is configured on the PE: This is a possible cause. The Provider Edge (PE) device (e.g., border leaf or router) must have a return route to the tenant's VXLAN network for external access. Without it, traffic from external networks cannot reach the DC. POSSIBLE CAUSE.
B . The engineer did not check whether the service loopback interface needs to be configured on the VXLAN network based on the switch model: This is a possible cause. Some Huawei switch models (e.g., CE series) require a service loopback interface as the VTEP source IP. If omitted or misconfigured based on the model, external connectivity fails. POSSIBLE CAUSE.
C . No firewall security policy is configured when host traffic passes through the firewall: This is a possible cause. If a firewall is in the path (e.g., between tenant VPC and external network), a missing security policy (e.g., allowing outbound traffic) blocks access. POSSIBLE CAUSE.
D . The MAC address of the NVE interface on the VXLAN network is not manually specified: This is not a possible cause. The Network Virtualization Edge (NVE) interface in VXLAN does not require a manually specified MAC address; it uses the switch's system MAC or auto-generates one. iMaster NCE-Fabric typically handles this automatically, and manual specification is neither required nor a common fault point for external access issues. NOT A POSSIBLE CAUSE.
Thus, D is not a possible cause of the fault.
질문 # 56
A financial enterprise is deploying an EVPN VXLAN fabric. The architects require automatic distribution of host MAC addresses while minimizing unknown unicast flooding between leaf switches. Which EVPN route type primarily advertises MAC reachability information?
정답:B
설명:
Type 2 routes advertise MAC addresses together with optional IP information, enabling remote VTEPs to learn endpoint locations. Type 1 is mainly for Ethernet segment discovery, Type 3 establishes BUM traffic distribution, and Type 5 advertises IP prefixes rather than endpoint MAC information.
질문 # 57
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)
정답:A,B,C,D
설명:
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.
