Huawei HCSP-Presales-Campus Network Planning and Design V1.0 認定 H19-401_V1.0 試験問題:

1. What are the characteristics of the simplified deployment function of SD-WAN controller?
(Multiple choice)

A) High requirements for network skills of opening personnel
B) Batch start
C) Quick to configure
D) Wizard style

2. The biggest change in optical-electrical hybrid cable 2.0 is that the optical-electrical hybrid switch ports change from optical-electrical separation to optical-electrical integration. Structural optimization makes the splicing and use of optical-electrical hybrid cables easier, while doubling the optical-electrical port density.

A) True
B) False

3. Which routing algorithm should be chosen in the following scenario: The enterprise rents telecom MPLS and three links, Internt1 and Internet2, and VOIP uses the MPLS link first. When the MPLS link is congested, low-priority applications are scheduled to other links. To prevent MPLS link quality cracks from affecting VOIP services?

A) Load balancing routing
B) Link quality routing
C) Bandwidth routing
D) Apply priority routing

4. The device has been added to the controller but there is no corresponding configuration result.
Which of the following is the possible reason? (Multiple choice)

A) The device is not online yet
B) System bug caused message loss and no configuration was generated.
C) The system is busy and needs to wait.
D) Device not added to site

5.
Refer to the diagram above, which statement about the original bandwidth mode is correct?
(Multiple choice)

A) The original bandwidth mode is not the default deployment mode of the tunnel. It is recommended to deploy this mode. The benefits are obvious, but the disadvantage is that some bandwidth is wasted.
B) As shown in the figure, the RT1->RT5 tunnel has a bandwidth of 1OM, the solid line is the working path, and the dotted line is the protection path. NCE deducts 10M bandwidth from all links that the primary and backup paths pass through. In this way, when the primary path fails, because the bandwidth of the backup path is reserved in advance, traffic is switched to the backup path without congestion.
C) When the policy creates two CPs, the tunnel will generate two paths, the primary path and the backup path. Generally, traffic is on the main path, and the backup path plays a protective role.
When the main path fails, the traffic can be switched to the backup path within 50ms. In order to ensure that traffic originally on the primary path will not cause congestion or even packet loss when switching to the backup path, NCE deducts bandwidth when calculating the primary and backup paths of the tunnel.
D) If the primary and backup paths share a common link, two bandwidths will be deducted for the shared link, not one bandwidth.
