H12-841_V1.5 Exam Training Practice Tests (Huawei HCIP-Datacom-Campus Network Planning and Deployment V1.5)]

Question 1

In Huawei's WAN bandwidth management solution, which of the following functions can "allow relaxed control over bandwidth usage during specific time periods (such as lunch break 12:00-
14:00), allowing non-critical services to temporarily occupy more bandwidth"?

A. The same control strategy is used for all time periods. B. Disable network access during lunch break to avoid bandwidth consumption. C. Bandwidth is controlled only during working hours; there is no control during lunch breaks. D. Time-based bandwidth control policy (quota adjustment within a time period)

Correct Answer: D

Question 2

In Huawei's WAN solution, regarding the issue of "intermittent stuttering in VoIP voice services," which of the following troubleshooting steps should be performed first?

A. Check if high-priority DSCP tags (such as EF) are configured for VoIP traffic. B. Check if the routing table of the CE device includes the headquarters network segment. C. Check the bandwidth usage of public internet services. D. Check if the hard drive storage capacity of the branch equipment is sufficient.

Correct Answer: A

Question 3

In Huawei's WAN solution, for " large files (e.g., over 10GB) transmitted across regions ", which of the following technologies can "achieve file segmentation and resume interrupted transmission, thus improving transmission reliability"?

A. File-segmented transmission technology (splitting files into small chunks for independent transmission) + resume interrupted download B. Reduce file transfer rate to decrease the probability of interruption. C. Transmit only when bandwidth is sufficient, and pause when bandwidth is insufficient. D. Transfer the entire large file directly without splitting it into chunks; if the transfer is interrupted, it needs to be retransmitted.

Correct Answer: A

Question 4

In Huawei's SD-WAN solution, which of the following technologies can "real-time monitoring of the health status of the VPN tunnel between branch devices and headquarters, triggering alarms when abnormalities occur "?

A. Tunnel connectivity detection based on ICMP ping (periodically sending ping packets, triggering an alarm if timeout occurs). B. Only monitor the physical status of the link, not the logical status of the tunnel. C. The tunnel condition is manually inspected periodically, and manual alarms are triggered when abnormalities are detected. D. Disable tunnel monitoring function and rely on service interruption to detect anomalies.

Correct Answer: A

Question 5

In Huawei's WAN bandwidth optimization solution, which of the following technologies can
"reduce data transmission volume and shorten backup time" for " large database backup files transmitted across regions"?

A. Block-based deduplication technology (transmitting only newly added/changed data blocks) B. Split the backup file into smaller files and transfer them separately, without changing the total data size. C. Reduce transmission bandwidth and force an extension of backup time. D. Directly transfer the original backup file without any optimization.

Correct Answer: A

Question 6

In Huawei's WAN solution, which of the following technologies can "quickly detect WAN link faults, achieve millisecond-level fault awareness, and shorten recovery time"?

A. OSPF hello protocol (default 10s detection) B. Manual ping test C. BFD (Bidirectional Forwarding Detection) D. Static route timeout mechanism (default 3 minutes)

Correct Answer: C

Question 7

In the OSPF protocol for wide area networks, which of the following is the core information contained in Type 2 LSA (Network LSA)?

A. Prefixes and metrics for external routes within the NSSA area B. Prefix and metric of inter-area summary route C. Prefix and next hop of external routes to the AS D. The DR router ID that generated this LSA and the IDs of all routers in the network.

Correct Answer: D

Question 8

In an MPLS VPN network, which of the following configurations is a necessary condition for "PE devices and CE devices to exchange routes via OSPF"?

A. Disable the BGP VPNv4 address family on the PE device and use only OSPF. B. Configure the OSPF protocol on the P device to transmit routes between the PE and CE. C. Enable the MPLS protocol on the CE device and support OSPF label forwarding. D. Enable the OSPF protocol under the VPN instance on the PE device and establish a neighbor relationship with the CE device.

Correct Answer: D

Question 9

In the deployment of the OSPF protocol in a wide area network, what is the core function of a "full stub area"?

A. Achieve indirect connection between non-backbone regions and Area 0. B. Disallow receiving Type 3/5/7 LSAs; only accept Type 1/2 LSAs and the default route, significantly reducing the number of route entries. C. Allows the import of external routes to the AS, while also receiving inter-area summary routes. D. Disable OSPF authentication and simplify the configuration process.

Correct Answer: B

Question 10

In an MPLS VPN network, when a PE device forwards data packets to a CE device, if the PE device fails to remove the inner VPN label, which of the following problems will occur?

A. The PE device automatically re-labels and then forwards the data. B. Data packets are forwarded to the CE device normally, without affecting services. C. The CE device cannot recognize the tag and discards the data packet. D. The P device is unable to forward data packets (missing public network label).

Correct Answer: C

Question 11

In a wide area network (WAN) OSPF network, in which of the following scenarios is it necessary to deploy "OSPF Virtual Links " to solve the problem of routing interoperability between areas?
(Multiple choice)

A. The backbone area Area 0 is divided into two parts, requiring virtual link connections. B. All areas are directly connected to Area 0, requiring no virtual links. C. In a Layer 2 network, OSPF virtual links are not required . D. Non-core regions (such as Area 1) are not directly connected to the core region (Area 0). E. Use only static routes to connect non-backbone areas; no virtual links are needed.

Correct Answer: A,D

Question 12

In Huawei's SD-WAN solution, for the scenario of "VPN communication between multiple branches", which of the following technologies can "achieve direct communication between branches without the need for headquarters relay"?

A. Only branch offices are allowed to access headquarters; direct communication between branches is prohibited. B. Manually creating point-to-point tunnels for each pair of branches is complex to configure. C. All inter-branch communication is relayed through headquarters, increasing latency. D. SD-WAN inter-branch full interconnection tunnel technology (dynamically establishing direct connection tunnels between branches)

Correct Answer: D

Question 13

In Huawei's SD-WAN solution, which of the following functions can "statistically calculate the percentage of encrypted traffic in the VPN tunnel between branch devices and headquarters, and generate a security report"?

A. Application Traffic Classification Statistics B. VPN Tunnel Traffic Encryption Statistics and Reports C. Link Quality Probe (LQM) D. Equipment hardware resource monitoring
