Which of the following IT transformations drive data center networks towards all-Ethernet?
A. PCIe is replaced.
B. The deployment mode evolves from single-cloud mode to multiple deployment modes such as multi- cloud mode.
C. The IT architecture evolves from centralized to distributed.
D. Storage media evolves from HDDs to SSDs.
答案：C,D
解題說明：
The transition to all-Ethernet data center networks is driven by several IT transformations. Below is an analysis of each option:
* PCIe is replaced : PCIe is a local bus standard used for high-speed device connections within servers.
Its replacement does not directly contribute to the shift toward all-Ethernet networks.
* Storage media evolves from HDDs to SSDs : The adoption of SSDs increases storage performance and reduces latency, making Ethernet-based storage protocols like NVMe over Fabrics (NVMe-oF) viable alternatives to traditional Fibre Channel.
* The IT architecture evolves from centralized to distributed : Distributed architectures require scalable and flexible networking solutions, which Ethernet-based networks are well-suited to provide.
* The deployment mode evolves from single-cloud mode to multiple deployment modes such as multi- cloud mode : While multi-cloud deployments influence network design, they do not directly drive the shift to all-Ethernet networks.
Thus, the correct answers are B and C .

A VXLAN solution has the following advantages: - Low construction requirements: VXLAN can be built on any complex Layer 3 network. ?Easy for automation: After the underlay network is enabled, what need to do is configure the devices at both ends of tunnels and it is easier for the controller to orchestrate. ?High standard compliance: VXLAN is a standard virtual network bearer technology in the industry.
Which of the following statements are correct about VXLAN implementation in Huawei CloudCampus? (Choose all that apply.)
A. Fabric Extension supports third-party switches and APs
B. VXLAN-to-aggregation is supported
C. VXLAN-to-access is supported
答案：B,C
問題 #137
Labels are used in MPLS forwarding. Which option can be used to configure labels?
A. Static routing
B. Direct routes
C. Manual configuration
D. Label Distribution Protocol (LDP)
答案：D
解題說明：
MPLS (Multiprotocol Label Switching) uses labels to forward packets efficiently along predefined paths called Label Switched Paths (LSPs). These labels are assigned dynamically using protocols likeLabel Distribution Protocol (LDP)or RSVP-TE (Resource Reservation Protocol - Traffic Engineering).While static routing and manual configuration can define paths, they do not involve dynamic label assignment. Similarly, direct routes are not related to MPLS label distribution. LDP is specifically designed to exchange label information between routers, enabling MPLS forwarding.
