Huawei HCSE-Presales-Campus Network Planning and Design V1.0 Sample Questions:
Question 1
Which of the following statements about antenna polarization are correct?
A. If the direction of the electric field of a radio wave is perpendicular to the ground, we call it a vertically polarized wave.
B. A dual-polarized antenna is a combination of two antennas with perpendicular polarization directions, which can achieve optimal diversity gain and save installation space.
C. The polarization of an antenna refers to the direction of the magnetic field strength formed when the antenna radiates.
D. The antenna radiates electromagnetic waves into the surrounding space, and the direction of its electric field changes according to a certain rule.
Question 2
Routers rely on hardware BFD and FR technology to achieve high reliability. FRR includes LDPFRR and VPNFR. LDPFRR is tunnel-level protection, while VPN FRR is service-level protection.
A. Error
B. Correct
Question 3
In high-density scenarios, what is the minimum signal-to-noise ratio (SNR) detected by the terminal to ensure a balance between bandwidth rate and signal coverage?
A. 30dB
B. 15dB
C. 25dB
D. 20dB
Question 4
When the CloudCampus solution is applied to small or medium-sized campus networks, which description of the access layer design is correct?
A. When selecting a switch, you need to calculate the number of connected APs * AP power < the power the POE switch can provide. Therefore, you need to choose a POE switch with an appropriate power supply based on the specific model and number of APs.
B. Select an appropriate access switch model based on whether PoE support is required and the number of access APs.
C. For micro-store scenarios where AP coverage is required, APs and egress devices must be deployed in the store. APs cannot be directly connected to egress links and do not support NAT.
D. For medium-sized supermarkets and general education scenarios with large network scales, a stacked network is recommended for the access layer. When a single access device can meet the access density of downstream terminals, a single-device network can be used at the access layer. When the upstream devices at the access layer use a stacked network, an Eth-Trunk link is recommended to connect the upstream devices. If multiple APs are required for coverage, expand AP access using POE LSW.
Question 5
What channel is used for data forwarding in Huawei's SD-WAN solution?
A. Data Channel
B. Forwarding channel
C. Control Channel
D. Management Channel
