Huawei HCIP-Routing&Switching-IERS(Huawei Certified ICT Professional-Implementing Enterprise Routing and Switching Network) - H12-221-ENU FREE EXAM DUMPS QUESTIONS & ANSWERS

A. The optimal route is route M, because its AS Path is shorter than route N. B. The optimal route is route M, because its MED is larger than route N. C. The optimal route is route N, because its MED is smaller than route M. D. The optimal route is route N, because its AS Path is longer than route N.

A. All multicast traffic passes through RP routers. RP routers may become the bottleneck for data forwarding. B. The RPT tree cannot be forwarded for a long time. C. The SPT path is the shortest and the forwarding performance is better. D. The RPT tree cannot support large traffic forwarding.

A. Enterprises can use the Principal PORT to connect to enterprise servers, separate PORT to connect enterprise customers and Group PORT to connect enterprise employees. In this way, enterprise customers and enterprise employees can access enterprise servers, and internal employees can communicate, enterprise customers cannot communicate, and enterprise customers and enterprise employees cannot communicate with each other. B. If the VLAN ID is already used for the principal VLAN, the VLAN can no longer be used for VLANIF interfaces, super VLANs and sub VLANs. C. After MUX VLAN is enabled on a port, you can use it again for VLAN mapping and VLAN stacking configuration. D. Each Group VLAN must have a Principal VLAN bound to it.

A. FALSE B. TRUE

A. True B. False

A. FALSE B. TRUE

A. >: indicates that the route is a valid route and the next hop is reachable. B. *: indicates that the route is a valid route and the next hop is reachable. C. >: indicates that the route is the optimal route selected by BGP. D. *: indicates that the route is the optimal route selected by BGP.

A. Aggregated routes carry the community attributes of all the original routes. B. Router A will advertise the details about the 168.32.0.0/16 network segment to neighbors. C. By setting the as-set keyword, you can create an aggregation route. The AS path of this route contains the AS path information of the specific route, and the AS number is ordered. D. The network segment 168.32.0.0/16 is aggregated by configuring this command.

A. The BGP protocol uses a reliable transmission protocol. B. Supports rich routing strategies. C. Support clear text verification. D. Supports automatic discovery of neighbors.

A. For the peer to send the route, the route-policy is processed first with the IP-Prefix. B. For the peer to send the route, the IP-Prefix is processed first with the router-policy. C. For the peer to receive the route, the route-policy is processed first with the IP-Prefix. D. For the peer to receive the route, the IP-Prefix is processed first with the route-policy.

A. VRP default ospf introduces external routes as the first type of external routes. B. The AS external cost value of the first type of external route is considered to be much larger than the AS internal cost value. C. The AS external cost value of the second type of external route is considered to be the same order of magnitude as the AS internal cost value. D. The AS external cost value of the first type of external route is considered to be the same order of magnitude as the AS internal cost value.
