How to Prepare For Huawei Implementing Enterprise Switching Network Training

Preparation Guide for Huawei Implementing Enterprise Switching Network Training

Introduction

The HCNP-R&S-IESN course has been designed to understand the technical knowledge around the principles of Ethernet, QinQ, 802.1X,STP/RSTP/MSTP, MPLS VPN, MPLS LDP, and DHCP technologies in an enterprise network. The course modules target the understanding of Ethernet application and configuration. The course outlines and explains the Huawei Ethernet switches and how they can be networked. Configuration of STP, MSTP and RSTP are also covered during the course delivery. The HCNP-R&S-IESN exam covers principles, configuration, and application of Ethernet, VLAN, QinQ, STP/RSTP/MSTP, 802.1X, DHCP, MPLS LDP, and MPLS VPN technologies in enterprise networks, and knowledge and networking application of Huawei Ethernet switches. VLAN technology provides flexible control for Ethernet, and is applied widely.Huawei H12 222 practice exams and Huawei H12 222 practice test will help you to understand and memorize the concepts and detailed answers and solutions.

The HCNP-R&S-IESN exam covers principles, configuration, and application of Ethernet, VLAN, QinQ, STP/RSTP/MSTP, 802.1X, DHCP, MPLS LDP, and MPLS VPN technologies in enterprise networks, and knowledge and networking application of Huawei Ethernet switches. With an HCNP-R&S certification, you demonstrate a comprehensive and thorough understanding of small and medium-sized networks, including general network technologies, and the ability to design small and medium-sized networks independently and implement the designs using Huawei routing and switching devices.

With engineers who are HCNP-R&S certified, enterprises are able to construct complete small and medium-sized networks and integrate voice, wireless, cloud, security, and storage technologies into their networks in order to support a variety of applications while providing enhanced security, availability, and reliability.

Candidate should give this exam who want:

• Describe the principle of VLAN, QinQ, STP, RSTP and MSTP
• Configure STP, RSTP and MSTP
• Configure VLAN, Mux VLAN, Super VLAN and QinQ

It can realize based on user identity, access time, access location, terminal type, terminal source and access mode (For shot: 5W1H) certification and authorization.

• True
• False

• True
• False

What is the configuration command that associates VRRP with BFD?

• vrrp vrid 1 track bfd-session-name 1 reduced 100
• bfd-session vrrp vrid 1 track session-name 1 reduced 100
• track vrrp vrid 1 bfd-session session-name 1 reduced 100

When configuring a RADIUS server template on Huawei switches, which of the following options are optional configuration parameters?

• RADIUS automatically detects users
• Authentication server address and port
• Accounting server address and port
• shared-key

In MPLS, it has different ways for label distribution when using LDP, the following descriptions about LDP lable distribution way, which are wrong? (Multiple Choice)

• Using a standalone mode, the LSR can send a label mapping to the upstream LSR and must wait for a label mapping message from the next hop of the LSR.
• The LDP label control can mark by Odered manner
• LDP label control can not use the independent way to mark.
• Using an ordered manner, when an LSR is the originating node of a route, the LSR does not need to wait for the next-hop tag mapping to send the mapping to the upstream.

There is a difference between RSTP protocol and STP protocol, in RSTP protocol when defining port status, which port states are defined?

• Learning state
• Discarding state
• Forwarding state
• All of the above

When configuring and achieving STP protocol, each running STP agreement's switch in the network all have a unique ID, what is the ID?

• six bytes length's switch priority and the six-byte length's MAC address
• two bytes length's switch priority
• two bytes length's switch priority and the six-byte length's MAC address
• six bytes length's MAC address

When running the STP agreement on the switch, the switch just being started is in the initialization stage and thought itself is the root switch, which of this time's BPDU parameter settings is correct? (Please select 3 answers)

• Designated Root is the switch itself
• Designated Cost is 0
• Designated Port is 0
• Designated Bridge is the switch itself

The following is a switch configuration command,

(SWB) STP enable (SWB) STP mode STP (SWB) the STP priority 8192

Which description is correct? (please select 3 answers)

• By default, Huawei switches operating mode is the traditional STP mode.
• stp priority commands is used to configure the switch priority, by default, the switch priority value is 32768.
• the priority of the switches, the range is 0 - 61440, the step length is 4096, namely the switch can set 16 priority values, such as 0, 4096, 8192.
• stp enable is used to start switch's STP function, by default, the switch's STP function is in the enabled function.
