H12-841_V1.5 Dumps with Practice Exam Questions Answers

In this scenario, O&M personnel need toview packet exchange processesduring Wi-Fi access and precisely locate the root cause of the failure. According to HCIP Datacom Campus Network documentation, theProtocol Tracefunction of iMaster NCE-CampusInsight is specifically designed for this purpose.

Protocol trace allows administrators to analyzereal packet interaction processesbetween clients, APs, gateways, and servers during key access phases such as authentication, IP address assignment, and service establishment. By tracing protocols like DHCP, ARP, and authentication exchanges, O&M personnel can clearly identify where the access process fails.

In the given case, mobile terminals fail to obtain IP addresses due toDHCP address pool exhaustion. This problem can only be accurately identified by observing the DHCP request and response flow, such as repeated DHCP Discover messages without successful Offer messages. Protocol trace visualizes this interaction step by step, making it easy to confirm that the DHCP server cannot allocate new IP addresses.

Other options do not match the scenario.Simulation feedbackis used to simulate access behavior rather than analyze real traffic.Issue analysisfocuses on aggregated fault statistics and trend analysis, not detailed packet-level inspection.Client journeytracks the overall user access path and experience stages but does not provide deep protocol packet visibility.

Therefore, the function used by O&M personnel to view packet exchange processes and identify DHCP pool exhaustion isProtocol trace, making optionAthe correct answer.

Comprehensive and Detailed 200 to 250 words of Explanation From HCIP Datacom Campus Network documents knowledge without any URL or Links:

IPsec defines two standard encapsulation modes that determine how IP packets are protected during transmission:Tunnel modeandTransport mode. Tunnel mode encapsulates the entire original IP packet within a new IP header and is typically used forsite-to-site VPNs. Transport mode encrypts only the payload of the IP packet and is commonly used forhost-to-host communication.

Switching mode and routing mode are not valid IPsec encapsulation modes and are unrelated to IPsec protocol behavior.

According to HCIP Datacom Campus Network documentation, onlyTunnel mode and Transport modeare supported in IPsec, makingoptions B and C correct.

In a VXLAN BGP EVPN network, different EVPN route types are used to advertise specific kinds of control-plane information.BGP EVPN Type 2 routes, also known asMAC/IP Advertisement routes, are primarily used to advertise Layer 2 and host-level Layer 3 reachability information between VTEPs.

According to HCIP Datacom Campus Network documentation, a Type 2 route carriesMAC address information, and it can optionally carry ahost IP addressassociated with that MAC. This enables efficient MAC learning and ARP suppression within the VXLAN fabric. TheL2VNIis also included in Type 2 routes, as it identifies the Layer 2 broadcast domain to which the MAC and IP information belongs.

TheL3VNIis not used to identify a Layer 2 broadcast domain but is associated with Layer 3 VPN forwarding and inter-VNI routing. While L3VNI information is relevant in EVPN-based Layer 3 services, it is not the primary identifier in a Type 2 route. However, the key distinction in this question lies in the difference between host routes and prefix routes.

AnIP prefixrepresents a network segment rather than a single host and is advertised usingEVPN Type 5 (IP Prefix) routes, not Type 2 routes. Type 2 routes only carry host IP addresses, not IP prefixes. Therefore,IP Prefixis not carried in a BGP EVPN Type 2 route, making optionCthe correct answer.

Huawei’s free mobility solution is designed to provide consistent user access control and policy enforcement across the campus network, regardless of user location. According to HCIP Datacom Campus Network documentation, the solution is built around severalclearly defined core roles, each with specific responsibilities.

Theauthentication deviceis a core role. It performs user authentication using methods such as 802.1X, MAC authentication, or portal authentication, and associates user identity information with IP addresses or security groups.

Thepolicy enforcement deviceis also a core role. It enforces security and access control policies based on IP-security group information, ensuring that traffic complies with defined policies wherever the user is connected.

iMaster NCE-Campusis another core component of the free mobility solution. It acts as the centralized management and control platform, responsible for policy definition, IP-security group management, and coordination of information distribution between authentication points and policy enforcement points.

Thepolicy control device, however, isnot a core roleexplicitly defined in Huawei’s free mobility architecture. Policy control functions are integrated into iMaster NCE-Campus rather than implemented as a separate standalone device role. Therefore, “policy control device” is not recognized as a core role in the free mobility solution.

As a result, option B is the correct answer, while the other options represent essential components of Huawei’s free mobility solution as defined in HCIP Datacom Campus Network materials.

iMaster NCE-Campus classifies network alarms into different severity levels to help administrators quickly understand the health status of the campus network and take appropriate actions. According to HCIP Datacom Campus Network documentation, alarms are typically categorized intocritical,major,warning, andinformationallevels, each represented by a distinct icon and color in the management interface.

In the displayed alarm summary, four types of icons are shown with corresponding numbers. Thered flame iconrepresents critical alarms, and the number next to it is0, indicating no critical alarms. Theorange lightning iconrepresents major alarms, and the number displayed is5, indicating five major alarms. Theyellow exclamation mark iconrepresentswarning alarms, and the number next to it is1. Finally, theblue information iconrepresents informational alarms, with a total of10.

Warning alarms indicate potential issues that do not immediately affect network operation but may develop into more serious problems if not addressed. These alarms require administrator attention but are less urgent than critical or major alarms. Accurately identifying the number of warning alarms helps prioritize troubleshooting and maintenance tasks.

Since the yellow warning icon shows the number1, this means there isone warning alarmcurrently generated on the network. Therefore, the correct answer is1, corresponding to optionB.
