NEW QUESTION # 280
During routine operation and maintenance, an engineer checks the IGMP configuration on RTA. The configuration is as follows:
Interface information of VPN-Instance: public net
GigabitEthernet0/0/1 (192.168.1.1):
IGMP is enabled
Current IGMP version is 2
IGMP state: up
IGMP group policy: none
IGMP limit: -
Value of query interval for IGMP (negotiated): -
Value of query interval for IGMP (configured): 60 s
Value of other querier timeout for IGMP: 0 s
Value of maximum query response time for IGMP: 10 s
Querier for IGMP: 192.168.1.1 (this router)
Given this, which of the following statements is false?

A. The IP address of the interface is 192.168.1.1.
B. The maximum response time to Query messages is 10s.
C. The IGMP version is IGMPv2.
D. The interval for sending Group-Specific Query messages is 60s.

Answer: D

Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
1. Understanding IGMP (Internet Group Management Protocol):
* IGMP is used in multicast networking to manage membership of devices in multicast groups.
* Key parameters in the configuration provided:
* Interface IP Address: 192.168.1.1
* IGMP Version: 2
* Query Interval (Configured): 60 seconds
* Maximum Query Response Time: 10 seconds
* Querier Address: 192.168.1.1
2. Analysis of Each Statement:
Option A: The IP address of the interface is 192.168.1.1.
* Correct (True Statement).
* The configuration clearly shows that the IP address of the interface is 192.168.1.1.
Option B: The maximum response time to Query messages is 10s.
* Correct (True Statement).
* The configuration explicitly mentions: Value of maximum query response time for IGMP: 10 s.
Option C: The interval for sending Group-Specific Query messages is 60s.
* Incorrect (False Statement).
* The 60-second value refers to the query interval, which is the time interval between general queries sent by the querier.
* The interval for group-specific queries is not specified in this configuration. It is determined dynamically based on the multicast environment and is usually shorter than the general query interval.
Option D: The IGMP version is IGMPv2.
* Correct (True Statement).
* The configuration specifies: Current IGMP version is 2.
3. Why Option C is False:
* The 60-second value is for general query interval, not group-specific query interval.
* The statement misinterprets the configuration, making it false.
4. Summary:
* Correct answer: C (The interval for sending Group-Specific Query messages is 60s).

NEW QUESTION # 281
On the network shown in the following figure, the management VLAN is VLAN 10, and the AP is configured 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?

A. [AC] dhcp server group AP
[AC-dhcp-server-group-AP] dhcp-server 10.1.1.2
[AC-dhcp-server-group-AP] quit
[AC] interface Vlanif 10
[AC-Vlanif 10] dhcp select relay
[AC-Vlanif 10] dhcp relay server-select AP
[AC-VlaniflO] quit
B. [AR] ip pool AP
[AR-ip-pool-AP] network 172.21.1.0 mask 24
[AR-ip-pool-AP] gateway-list 172.21.1.2
[AR-ip-pool-AP] excluded-ip-address 172.21.1.1
[AR-ip-pool-AP] quit
[AR] interface GigabitEthernet 0/0/1
[AR-GigabitEthernetO/0/1] dhcp select global
[AR-GigabitEthernetO/0/1] quit
[AR] ip route-static 10.1.1.0 255.255.255.0 172.21.1.1
C. [AC] dhcp server group AP
[AC-dhcp-server-group-AP] dhcp-server 172.21.1.2
[AC-dhcp-server-group-AP] quit
[AC] interface Vlanif 10
[AC-Vlanif 10] dhcp select relay
[AC-Vlanif 10] dhcp relay server-select AP
[AC-Vlanif 10] quit
D. [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
[AR] interface GigabitEthernet 0/0/1
[AR-GigabitEthernetO/O/1] dhcp select global
[AR-GigabitEthernet0/0/l] quit
[AR] ip route-static 10.1.1.0 255.255.255.0 172.21.1.1

Answer: C,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 to 10.1.1.0 through 172.21.1.1 ensures proper routing .

NEW QUESTION # 282
In a route-policy, which of the following BGP attributes can be used in apply clauses?

A. MED
B. Local-Preference
C. AS_Path
D. Tag

Answer: A,B

Explanation:
In a route-policy, attributes such as MED (Multi-Exit Discriminator) and Local-Preference can be used in apply clauses to influence BGP route selection. Attributes like AS_Path and Tag are typically matched or filtered but not directly applied in the apply clause .

NEW QUESTION # 283
Which of the following routing protocols support the default route through command configuration?

A. BGP
B. IS-IS
C. OSPF
D. ICMP

Answer: A,B,C

Explanation:
BGP, IS-IS, and OSPF support the configuration of default routes through specific command configurations.
For example, BGP uses the default-originate command, IS-IS uses a default-route-advertise method, and OSPF can advertise default routes using default-information originate. ICMP, however, is not a routing protocol and does not support this functionality .
