1Which OSI layer is responsible for end-to-end logical addressing and path determination between hosts on different networks?

A.Data Link layer

B.Network layer

C.Transport layer

D.Session layer

Explanation: The Network layer (Layer 3) handles logical addressing such as IP and decides the path that packets take between hosts in different networks. Routers operate at this layer.

2In the TCP/IP reference model, which layer aligns with the OSI Network layer?

A.Network access layer

B.Internet layer

C.Transport layer

D.Application layer

Explanation: The TCP/IP Internet layer corresponds to the OSI Network layer. It uses IP, ICMP, and ARP-related protocols to provide logical addressing and routing.

3How many bits long is a standard Ethernet MAC address?

A.32 bits

B.48 bits

C.64 bits

D.128 bits

Explanation: A standard Ethernet MAC address is 48 bits long, usually written as 12 hexadecimal characters such as 00-1A-2B-3C-4D-5E. The first 24 bits identify the vendor (OUI).

4A host needs to send a packet to a destination on the same subnet but does not yet know the destination MAC address. Which protocol does it use?

A.DNS

B.ARP

C.ICMP

D.DHCP

Explanation: ARP (Address Resolution Protocol) maps a known IPv4 address to a MAC address by broadcasting an ARP Request and learning from the unicast ARP Reply.

5Which ICMP message type does the ping utility use as its echo request?

A.Type 0

B.Type 3

C.Type 5

D.Type 8

Explanation: Ping sends ICMP Echo Request messages with type 8 and expects type 0 Echo Reply messages back from the destination.

6Which transport-layer protocol provides reliable, connection-oriented delivery using a three-way handshake?

A.UDP

B.TCP

C.ICMP

D.IP

Explanation: TCP establishes a connection with a SYN, SYN-ACK, ACK three-way handshake and uses sequence numbers, acknowledgments, and retransmissions to provide reliable delivery.

7Which Huawei VRP command mode allows you to enter global configuration commands such as creating a VLAN?

A.User view

B.System view

C.Interface view

D.Diagnostic view

Explanation: After running system-view from user view, you enter system view, where you can create VLANs, configure routing, and access subordinate views such as interface view.

8Which VRP command saves the current running configuration to the startup configuration file?

A.save

B.write memory

C.copy run start

D.commit

Explanation: On Huawei VRP, the save command in user view writes the running configuration to the saved-configuration file used at next startup.

9On Huawei VRP, which keyword negates or removes a previously configured command?

A.no

B.delete

C.undo

D.clear

Explanation: VRP uses the undo keyword to negate a configuration. For example, undo ip address removes a configured IP from an interface.

10Which command displays the current running configuration on a Huawei VRP device?

A.display version

B.display current-configuration

C.display saved-configuration

D.show running-config

Explanation: display current-configuration shows the configuration that is currently active in memory on a VRP device.

About the Huawei HCIA-Datacom Exam

Huawei HCIA-Datacom Study Tips from Top Performers

1Build comfort moving through the VRP views (user, system, interface, VLAN), and practice the most common commands such as system-view, undo, save, and display current-configuration until they are automatic.

2Spend the most time on VLANs, STP, and OSPF, because together they account for the largest share of question opportunities and underlie almost every campus design scenario.

3Drill VRP-specific syntax differences from Cisco IOS: port link-type, port trunk allow-pass vlan, ip route-static, ospf 1, traffic-filter inbound acl, and display commands instead of show.

4Practice end-to-end troubleshooting with display ip routing-table, display ip interface brief, display arp, display ospf peer, ping, and tracert so you can quickly localize Layer 2, Layer 3, or routing problems.

5For WLAN, learn the split MAC architecture, CAPWAP control on UDP 5246 and data on UDP 5247, the difference between centralized and local forwarding, and basic security with WPA2 and WPA3 SAE.

6Do not skip IPv6: know address types and prefixes (FE80::/10, FF02::1, FF02::2), how Neighbor Discovery replaces ARP, and the difference between stateful and stateless DHCPv6.

7Spend a focused block on the V3.0 automation topics: iMaster NCE, NETCONF over SSH with YANG, telemetry vs SNMP, OPS Python scripts on the device, and Ansible playbooks against VRP.

Frequently Asked Questions

How many questions are on the HCIA-Datacom (H12-811 V3.0) exam and how long is it?

The HCIA-Datacom H12-811 V3.0 exam contains 60 questions, including single-choice, multiple-choice, true/false (judgement), and drag-and-drop items. You have 90 minutes to complete the exam.

What is the passing score for HCIA-Datacom?

The passing score is 600 out of a 1000-point scaled score. Question difficulty is weighted, so the number of questions you can miss depends on which items you answer correctly, not on a flat percentage.

How much does the exam cost and where do I take it?

The exam fee is US$200. It is delivered worldwide through Pearson VUE test centers and online proctoring. You register through Huawei's certification site or directly via Pearson VUE.

How long is the HCIA-Datacom certification valid?

The certification is valid for three years. To maintain the credential you must recertify before it expires, either by retaking the current HCIA exam or by passing a higher-level Datacom certification.

What does HCIA-Datacom cover that earlier versions did not?

V3.0 expands beyond classic switching and routing to include more SDN and automation content. This includes Huawei iMaster NCE, NETCONF and YANG, telemetry, and basic Python and Ansible scripting for network operations.

Do I need hands-on Huawei VRP experience?

Strongly recommended. Many questions test VRP-specific commands such as port link-type, ip route-static, traffic-filter, and display ip routing-table, so spending time on a real or simulated Huawei device improves recall and judgement.

What can I do after passing HCIA-Datacom?

HCIA-Datacom positions you for junior network engineer roles in Huawei-based environments and serves as the foundation for higher Datacom certifications such as HCIP-Datacom and HCIE-Datacom, which open more advanced design and operations roles.
