Question # 41

As shown in the figure in the Multi-PoD solution of the CloudFabric solution, in the active/standby egress scenario, when the Border Leaf is the primary failure, the VM belonging to VPC1 is located What traffic path will be used to access the external network?

Question # 42

In microsegmentation, if the EPG packet information corresponding to the source IP exists in the source leaf, there is no EPG packet message corresponding to the destination IP on the destination side Which of the following behaviors is correct?

On the target side, the leaf matches the default access control policy of the EPG group members

On the source side, Leaf matches the default access control policy of the EPG group members

On the source side, the leaf matches the default access control policy of the unknown EPG group member

On the target side, the leaf matches the default access control policy of the unknown EPG group member

Question # 43

Which of the following descriptions of RDMA is wrong?

RDMA requires the host CPU to participate in multiple copies of protocol stack memory, resulting in a sustained high load on the CPU

Unlike traditional TCP socket network interfaces, RDMA bypasses the operating system kernel and implements kernel bypass

RDMA technology is widely used in scenarios such as HPC, AI, and storage, reducing CPU load and processing latency, and greatly improving application performance

RDMA enables peripherals (such as network cards) to directly access the memory of the remote host

Tenant: The basic unit of enterprise business management, and a tenant can only create one VPC

Logic Router: Used to connect VMs located on different networks, ensuring that VMs can communicate with other VMs across a three-layer network

Logic Switch: Used to connect different VMs to ensure that VMs can communicate with other VMs within the Layer 2 network

LoadPortVM is an access point into the network, and a physical port of a network device can be virtualized as multiple LoaicPorts

Question # 46

In micro-segmentation, if the source leaf has the EPG packet information corresponding to the source IP, the destination leaf has the EPG group information corresponding to the destination IP EPG group information, but there is no user-configured EPG intergroup policy for both Leaves, which of the following behaviors is correct by default?

Service packets can be sent from the source to the destination

Leaf discards service packets on the source side

On the destination side, Leaf discards service packets

The processing of service packets depends on the default access control policy of the unknown EPG group members of the source leaf
