Huawei HCIP-Routing&Switching-IENP(Huawei Certified ICT Professional-Improving Enterprise Network Performance) - H12-222 Exam Practice Test

A. The system automatically assigns an ID to the upper-layer application that uses a tunnel. This ID is also called the tunnel ID. B. After an IP packet enters an MPLS domain, the device receiving the packet queries in the FIB table first. C. If the tunnel ID is 0x0, the MPLS forwarding process starts. D. If the tunnel ID is not 0x0, the normal IP forwarding process starts.

A. FALSE B. TRUE

A. Configure the DHCP Option 82 field. B. Enable DHCP globally. C. Configure the global address pool if the DHCP server based on the global address pool is used. D. Configure the interface address pool if the DHCP server based on the interface address pool is used.

A. The master sends gratuitous ARP packets, and notifies the connected device or host of its virtual MAC address. B. If the master fails, the new master is selected among backup devices based on priorities. C. The master in the VRRP group is selected based on priorities. D. The priority ranges from 1 to 255. When the backup received VRRP Advertisement packets which the priority is 0, the backup discards the packets.

A. During traffic control, GTS enables the device to buffer packets of which the rate is exceeded into queues. B. During traffic control, LR enables the device to discard the packets of which the rate is exceeded. C. During traffic control, CAR enables the device to discard the packets of which the rate is exceeded. D. During traffic control, LR enables the device to buffer the packets of which the rate is exceeded and to send packets to QoS queues.

A. Leased lines are expensive. B. Private routes cannot communicate with each other. C. The address space is overlapping. D. Bandwidth resources cannot be fully used.

A. After global mpls is enabled, you do not need to enable mpls again in the interface view. B. mpls enables mpls in the system view and interface view. You can configure lsr-id only after mpls is enabled. C. mpls lsr-id is the ID of the LSR. It is a prerequisite for configuring other MPLS commands. The default is not configured. D. The last command configures LSRA as the inbound LSR and configures a static LSP.

A. By specified IP address segment B. By specified product model C. By specified IP address D. Batch import by Excel file (containing specified IP addresses)

A. Untrusted zone B. Local zone C. Security zone D. Trusted zone

A. FALSE B. TRUE

A. Confidentiality B. Authentication C. availability D. integrity

A. Network architecture virtualization B. Network function virtualization C. Network infrastructure virtualization D. Network bus virtualization

A. An LSR retains labels from a neighboring LSR only when the neighbor is its next hop. B. This label retention mode saves the memory and label space. C. An LSR reserves all labels sent by its neighbor. D. The liberal mode requires more memory and label space. E. This label retention mode reduces the LSP convergence time when the IP routes converge and the next hop changes.

A. They must be the same. B. They may be the same. C. They must be different.
