NEW QUESTION # 113
Which of the following descriptions of headroom caching is correct in CloudFabric lossless networking?
- A. The headroom cache is used to store packet D. received from the time when the queue sends a PFC backpressure notification packet to before the upstream device stops sending packets Headroom cache space actually occupies the shared cache of the outbound queue
- B. Headroom cache space actually occupies the Guaranteed cache of the inbound queue
- C. The headroom cache room is fixed at 20M
Answer: A
Explanation:
Analysis: The headroom cache space occupies the shared cache of the inbound queue, because the cache of the queue is allocated by the port cache, and the cache of the port is allocated by the plane cache, so only when the plane cache is sufficient, can the sufficient headroom be guaranteed Cache space to ensure lossless packet forwarding of lossless queues. The Ranging Headroom check function allows you to calculate the amount of cache space you need based on the configured port long-haul mode (i.e., link distance) and port rate.
NEW QUESTION # 114

NEW QUESTION # 115
OpenStack abstracts networks based on Neutron components, including Network, Subnet, and Port Which one is wrong?
- A. The virtual machine is associated with the network through a port
- B. Network is an isolated Layer 2 network, including VLANs and VXLANs
- C. Neutron's ML2 plug-in components provide Network, Subnet, and Port services
- D. A subnet is an IPv4/IPv6 address segment, and the subnet needs to be mapped to the network
Answer: D
Explanation:
Resolution: Subnet and network are not a one-to-one relationship. is an n:1 relationship, and a subnet must be associated with a network
NEW QUESTION # 116
Which of the following descriptions of Kubernetes' network solution, Macvlan, is wrong?
- A. MACVLAN requires the physical NIC to support promiscuous mode, the container gateway is on the physical switch, and the container IP relies on manual configuration and management
- B. Macvlan is an L2 bridging scheme
- C. Macvlan is one of the features of Linux Kernel, and it is also a network solution that can be natively supported by Docker
- D. The Macvlan scheme naturally supports automatic assignment of container IP addresses
Answer: D
Explanation:
Analysis: Macvlan is one of the features of Linux Kernel, and it is also a network solution that can be natively supported by Docker, which is configured through Macvlan for container networks and host networks Containers have the same network capabilities as hosts, and cross-node container access does not require NAT. Macvlan can be used on one of the host's network interfaces either Multiple virtual network interfaces are configured on the VLAN sub-interfaces for use by the container, and these virtual network interfaces have independent MAC addresses and IP addresses. *Macvlan requires a physical NIC to support promiscuous mode, and the container gateway is on the physical switch, which has the disadvantage of not having IPAM (IP Address Mangement) and container IP Rely on manual configuration and management.
