NEW QUESTION # 26
What are the correct descriptions of VXLAN Overlay multicast in the following descriptions?
- A. The VXLAN tunnel can still be configured as headend replication without special configuration
- B. BGP NG MVPN carries I-PMSI information for I-PMSI tunnel establishment
- C. There is no need to deploy multicast in the underlay
- D. When deploying multicast using PIM-SM mode, separate RPs need to be deployed on both the underlay and the overlay
Answer: B,D
Explanation:
Analysis: *The RP of the underlay multicast network needs to be configured in the VPN instance that carries the overlay multicast traffic for the overlay network RP of an overlay multicast network . That is, the RP of both the underlay and the overlay need to be configured in the same physical network (in the figure, Public VRF refers to the underlay ). The network control plane is not a VPN entity that carries specific services Example). * Since the access location of the overlay service multicast source is uncertain, the underlay multicast uses the ASM service model. *Configure PIM SM function enablement on all Layer 3 interfaces of Leaf and Spine interconnection, built on top of the PIM SM protocol Underlay multicast trees. *From the perspectives of network architecture, stability, and alleviating the pressure on VTEP devices, it is recommended that Spine do RP and publish the RP address to Underlay Network. To alleviate the burden of a single RP, implement RP backup, optimize the multicast data forwarding path, and deploy Anycast RP on 2 Spines with dual-node redundancy.

NEW QUESTION # 33
In the Multi-Site scenario of a CloudFabric solution, what are the correct items in the following description of Layer 2 interoperability?
- A. In practice, different sites have their own independent VNI space, so VXLAN tunnels inside different sites are likely to use different VNI C. Layer 2 interconnection is supported in two modes: local VNI and mapped VNI
- B. In the mapped VNI mode, the Fabric GW at both ends uses BGP EVPN to negotiate a mapped VNI, and all packets sent to the peer end are routed using the mapped VNI VXLAN packing
- C. In local VNI mode, the local VNI of the local Fabric GW is used as the outbound VXLAN packet to encapsulate VXLAN packets to the VNI
Answer: A,B,C
Explanation:
Resolution: Option A is correct, the mapped VNI is the VNI used for communication between data centers .
Option B is correct, multi-site uses the segment vxlan interconnect scheme, so the fabric gw will terminate the DC or Fabric , so the DC can have its own independent VNI space. Option C is correct, local VNI mode and mapped VNI mode are the two modes currently supported by L2 interworking, but some models of switches do not support local VNI mode, this needs to refer to the switch manual. The D option is wrong, in local vni mode, the fabric gw outbound direction is encapsulated with the other party's vni as the outbound direction .
NEW QUESTION # 34
Which of the following descriptions of data center interconnection solutions is wrong?
- A. In SegmentVXLAN mode, EVPN routes are transmitted in a three-stage mode to implement L3 communication between data centers
- B. The VLAN hand-off mode enables L2 communication between data centers
- C. The E2E EVPNVXLAN mode directly establishes a VXLAN tunnel between the VTEPs in two data centers
- D. After a VXLAN is established in the local mode in the segment VXLAN mode, packets are encapsulated with the local DCILeaf when they arrive at the local DCI Leat and are sent to the peer DCI Leat VNI, not the VNI of the peer DCI Leaf
Answer: D

Which of the following descriptions of the RTT requirements between different PoDs is correct in the Multi-PoD scenario of the CloudFabric solution?
- A. No more than 1s
- B. No more than 10ms
- C. No more than 100ms
- D. No more than 50ms
Answer: D
Explanation:
Analysis: When using the Multi-PoD solution, it is recommended that the iMaster NCE-Fabric and the central DC device pull the RTT latency by <=50 ms. It is recommended that the iMaster NCE-Fabric and Edge DC Leaf extend the RTT latency by <=300 ms. If the active/standby disaster recovery deployment mode of iMaster NCE-Fabric controllers is used, the latency between controllers is < = 20 ms.

NEW QUESTION # 44
Which of the following options is wrong in the description of the characteristics of the L2 bridging solution in the container network scenario of the CloudFabric solution?
- A. Multiple virtual network interfaces can be configured on a single network interface or VLAN subinterface of a host
- B. NAT is required for cross-node container access
- C. Virtual network interfaces have separate MAC addresses and IP addresses
- D. Containers have the same networking capabilities as hosts
Answer: B
Explanation:
Resolution: Options A and B are correct, multiple virtual interfaces are assigned to multiple containers. Each container has its own protocol address, MAC and IP. Option C is correct, all containers use a sub-interface or VLAN interface on the network interface to access the network that the host can access. The D option is incorrect, please refer to the image below. *Macvlan is one of the features of Linux Kernel, and it is also a network solution that can be natively supported by Docker The configured container network belongs to the same LAN as the host network, and the container has the same network capabilities as the host, and cross-node container access does not require NAT. MacVLANs allow you to configure multiple virtual network interfaces to containers on a network interface or VLAN sub-interface of the host These virtual network interfaces have separate MAC addresses and IP addresses. *Macvlan requires the physical NIC to support promiscuous mode, and the container gateway is on the physical switch, which has the disadvantage of no IPAM (IP Address Mangement) and container IP Rely on manual configuration and management
