NEW QUESTION # 298
On an STP network, the root bridge, root port, and designated port are elected in sequence. The election rules of these ports are different. List the steps for electing the root port in sequence.
Answer:
Explanation:
Explanation:
The sequence of steps for electing the root port in an STP (Spanning Tree Protocol) network is as follows:
* Bridge ID Comparison: The Bridge ID (BID) is compared between the bridges in the network. A smaller value indicates a higher priority, meaning the bridge with the lowest Bridge ID is elected as the root bridge.
* RPC (Root Path Cost) Comparison: The path cost to reach the root bridge is calculated. The router with the lowest Root Path Cost (RPC) to the root bridge will have a higher priority for the election of the root port.
* Peer BID Comparison: If there is a tie in the Root Path Cost, the Peer BID is compared. A smaller Peer BID indicates a higher priority. This step ensures that if two routers have the same RPC, the one with the lower Peer Bridge ID wins.
* Local BID Comparison: If there is still a tie, the Local BID is compared. A smaller Local BID indicates a higher priority. This final step ensures that the router with the lowest local identifier is selected.
* Bridge ID Comparison:The first step in electing the root port is comparing the Bridge IDs. The bridge with the lowest Bridge ID becomes the root bridge. The Bridge ID is made up of the bridge priority and MAC address. The root bridge is the center of the network for STP, and all other ports will calculate their paths based on this root.
NEW QUESTION # 299
An enterprise uses OSPF to implement network communication. To ensure data validity and security, all authentication modes supported by OSPF are enabled on routers. In this case, interface authentication is preferentially used by the routers.
Answer: B
Explanation:
OSPF Authentication Overview
OSPF supports three authentication modes:
Null Authentication: No authentication (default).
Plaintext Authentication: Uses clear-text passwords.
MD5 Authentication: Secure cryptographic authentication.
Interface-Level Priority
When both interface-level and area-level authentication are configured, OSPF prioritizesinterface-level authentication. This ensures that interface-specific security overrides area-wide configurations for greater granularity and security.
HCIP-Datacom-Core Reference
OSPF authentication hierarchy and configurations are detailed in the OSPF security configuration chapter.
NEW QUESTION # 300
On the network shown in the following figure, the management VLAN is VLAN 10, and the AP isconfigured to obtain an IP address on the network segment 10.1.1.0/24 through DHCP. The AP, AC, and AR function as the DHCP client, DHCP relay agent, and DHCP server, respectively. Which of the following configurations for the DHCP relay agent and DHCP server are correct?
Answer: A,D
Explanation:
Option A correctly configures the DHCP relay agent (AC) to forward requests to the DHCP server using VLAN 10.
Option B correctly configures the DHCP server (AR) with the correct IP pool (10.1.1.0/24), gateway, and excluded IP addresses. The static route to10.1.1.0through172.21.1.1ensures proper routing .
=========
NEW QUESTION # 301
On-board AC refers to the built-in AC capability of Huawei agile switches to achieve integrated management of wired and wireless services. The traffic of wired and wireless services is unified and centrally managed by the agile switches.
Answer: B
NEW QUESTION # 302
An enterprise administrator configures route summarization on ASBRs to reduce the number of inter-area Type 3 LSAs, which in turn reduces the routing table size and improves device resource utilization.
Answer: B
Explanation:
OSPF Route Summarization:
Route summarization combines multiple specific routes into a single summary route. This reduces the number of LSAs advertised between OSPF areas, especially Type 3 LSAs.
Benefits of Route Summarization:
Reduces the size of the OSPF database and routing table.
Minimizes the processing overhead on routers by decreasing the number of routing entries.
Improves the scalability of the OSPF network.
ASBR Function:
The ASBR advertises external routes into OSPF and can summarize routes at area boundaries or during redistribution.
