Huawei HCIP-Datacom-Core Technology V1.0 Sample Questions (Q65-Q70):

NEW QUESTION # 65
GRE is a Layer 2 VPN encapsulation technology that encapsulates packets of certain data link layer protocols so that the encapsulated packets can be transmitted over an IP network.

  • A. TRUE
  • B. FALSE

Answer: B

Explanation:
GRE (Generic Routing Encapsulation) is not a Layer 2 VPN technology. Instead, it is a Layer 3 tunneling protocol used to encapsulate a wide variety of network layer protocols inside point-to-point connections. GRE is commonly used for creating VPN tunnels across IP networks, allowing for the transport of various types of payloads. This misunderstanding about GRE being a Layer 2 technology contradicts its definition and typical application .


NEW QUESTION # 66
Which of the following methods is usually used by a network administrator to configure a newly purchased device for the first time?

  • A. SNMP
  • B. Login through the Console port
  • C. Telnet
  • D. FTP

Answer: B

Explanation:
For first-time configuration of a newly purchased network device, administrators typically use the console port. This direct connection is secure and independent of network configuration, making it suitable for initial setups. Telnet, SNMP, or FTP require prior IP configuration, which is not feasible during the initial setup phase .


NEW QUESTION # 67
In addition to numerous normal service packets, the CPUs of devices on a network may also receive large numbers of attack packets. To ensure that the CPUs can properly respond to normal services, the devices provide the local attack defense function.
Which of the following statements are true about this function?(Select all that apply)

  • A. To ensure that session-based application-layer data runs properly during an attack, you can configure the dynamic link protection function.
  • B. The device can schedule the protocol packets to be sent to the CPU in the attack defense policy based on the protocol priorities so that the packets with higher priorities are processed preferentially.
  • C. Regardless of the packet type, the same rate limit must be set to reduce the number of packets sent to the CPU.
  • D. CPU attack defense can also take effect on the management interface of the device.

Answer: A,B,D

Explanation:
A is correct- Local attack defense can classify and prioritize packets (e.g., OSPF, BGP, SSH) andensure critical protocols are processed firstby the CPU.
B is correct- Thedynamic link protection functionensures session-based applications (like SSH)are not disruptedeven during a CPU attack.
C is false- Different protocols havedifferent importance levels, soindividual rate limitsshould be configured, not a uniform one.
D is correct- CPU protectionalso applies to management interfaces, such as those used for Telnet, SSH, or SNMP.
Reference from Huawei HCIP-Datacom-Core Technology Study Guide:
"Devices support local attack defense by classifying packets, setting priorities, and limiting rates to protect CPU resources. These policies also apply to the management interface." (Chapter: Network Security - Section: Local Attack Defense)


NEW QUESTION # 68
A wide area network (WAN) is a remote network that connects local area networks (LANs) or metropolitan area networks (MANs) in different areas for communication purposes. It is typically used to interconnect campus networks or data center networks.

  • A. FALSE
  • B. TRUE

Answer: B

Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
* WAN Definition:
* A WAN is a large-scale network spanning a wide geographical area, connecting smaller networks such as LANs and MANs.
* Use Cases:
* WANs are commonly used for interconnecting campus networks, branch offices, and data centers over long distances.
* Correct Statement:
* The statement accurately describes the purpose and scope of WANs.
References:
* HCIA-Datacom Study Guide, Chapter: WAN Fundamentals
* Huawei Networking Basics


NEW QUESTION # 69
OSPF networks are classified into four types of networks by link layer protocol. Drag the following link layer protocols to the corresponding network types.(Token is reusable)

Answer:

Explanation:
Network Types and Corresponding Link Layer Protocols
Broadcast: Ethernet
Point-to-Point (P2P): PPP, HDLC
Point-to-Multipoint (P2MP): PPP
Non-Broadcast Multi-Access (NBMA): Frame Relay
OSPF Network Types:
OSPF classifies networks based on link layer protocols into the following types:
Broadcast: This type assumes that all routers on the network can communicate directly with one another using multicast or broadcast frames. Ethernet networks are typical examples.
Point-to-Point (P2P): This type is used for links that connect two routers directly. Common protocols include PPP (Point-to-Point Protocol) and HDLC.
Point-to-Multipoint (P2MP): This type simulates multiple point-to-point connections over a single physical network, often used in WAN scenarios where PPP is employed.
Non-Broadcast Multi-Access (NBMA): These networks connect multiple devices but lack native broadcast capability, such as Frame Relay.
Reference: HCIP-Datacom-Core Technology Training Material (OSPF Network Types).
Explanation of Matches:
Broadcast - Ethernet: Ethernet supports broadcast and multicast communication, making it a suitable example of a broadcast OSPF network.
P2P - PPP, HDLC: Both PPP and HDLC are designed for direct communication between two nodes, fitting the P2P category.
P2MP - PPP: In WANs, PPP often operates in a point-to-multipoint configuration, simulating separate connections for each endpoint.
NBMA - Frame Relay: Frame Relay is a classic NBMA technology where direct communication between devices requires manual configuration, as there is no inherent broadcast capability.
Conclusion:This classification ensures that OSPF operates efficiently over different network types by adapting neighbor discovery and LSA propagation mechanisms to the underlying link layer technology.
