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?

A. [AR] ip pool AP
[AR-ip-pool-AP] network 10.1.1.0 mask 24
[AR-ip-pool-AP] gateway-list 10.1.1.2
[AR-ip-pool-AP] excluded-ip-address 10.1.1.1
[AR-ip-pool-AP] quit

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 to 10.1.1.0 through 172.21.1.1 ensures proper routing .

A. A device with a higher router priority has a higher election priority.
B. If two devices have the same router priority, the device with a larger router ID has a higher election priority.

NEW QUESTION # 104
BGP routes have multiple path attributes. When a router advertises a BGP route to its peers, the route carries multiple path attributes. These attributes describe the characteristics of the BGP route and affect route selection in some scenarios. The attribute is Huawei-specific. It is valid only on the local device and is not transmitted to BGP peers. (Enter the attribute name in lowercase as it appears in the command output about the BGP routing table.)

Answer:

Explanation:
preference
Explanation:
BGP routes have a variety of path attributes that describe their characteristics and influence route selection.
These attributes include well-known mandatory attributes like AS-PATH and NEXT-HOP, as well as optional attributes like MED and LOCAL_PREF.
In Huawei devices, there is a Huawei-specific attribute called "preference", which is a local parameter used to influence BGP route selection on the device.
* Key Characteristics of "preference":
* It is valid only locally on the router.
* It is not shared with BGP peers.
* It helps the router determine the best route when multiple routes exist for the same prefix.
* It appears in the BGP routing table output in lowercase as preference.
Thus, the correct answer is preference (entered in lowercase as required).
References:
* Huawei HCIA-Datacom Study Guide, Chapter on "BGP Attributes".

NEW QUESTION # 105
Which of the following statements regarding the display bgp routing-table command output is true?

A. The MED value of the route to the destination address 192.168.1.0 is 100.
B. The route to the destination address 192.168.1.0 is not the optimal route in the BGP routing table.
C. The route to the destination address 192.168.1.0 is injected into the BGP routing table using the network command.
D. The route to the destination address 192.168.1.0 is learned through AS 200.

Answer: C

Explanation:
The Origin attribute in the display bgp routing-table output is marked as i, indicating that the route was injected into the BGP routing table using the network command. The other options are incorrect because the AS path is not displayed, the MED is 0, and the route is marked as the best (>), meaning it is the optimal route
