最新的 JNCIS-ENT JN0-351 免費考試真題 (Q66-Q71):

問題 #66
You have DHCP snooping enabled but no entries are automatically created in the snooping database for an interface on your EX Series switch. What are two reasons for the problem?
(Choose two.)

答案：A,D

解題說明：
If the device connected to the interface has performed a DHCPRELEASE, it releases its IP address back to the DHCP server, resulting in the removal of the corresponding DHCP snooping entry.
If the device connected to the interface is using a static IP address, it will not send DHCP requests, and therefore no entries will be created in the DHCP snooping database for that device.


問題 #67
An update to your organization's network security requirements document requires management traffic to be isolated in a non-default routing-instance. You want to implement this requirement on your Junos-based devices.
Which two commands enable this behavior? (Choose two.)

答案：B,D

解題說明：
Explanation
To isolate management traffic in a non-default routing-instance on Junos-based devices, you can use the set system management-instance and set routing-instances mgmt_junos commands12.
set system management-instance: This command associates the management interface (usually named fxp0 or em0 for Junos OS, or re0:mgmt-* or re1:mgmt-* for Junos OS Evolved) with the non-default virtual routing and forwarding (VRF) instance1. After you configure the non-default management VRF instance, management traffic no longer has to share a routing table with other control traffic or protocol traffic1.
set routing-instances mgmt_junos: This command creates a new routing instance named mgmt_junos. The name of the dedicated management VRF instance is reserved and hardcoded as mgmt_junos; you cannot configure any other routing instance by the name mgmt_junos1.
Therefore, options C and D are correct. Options A and B are not correct because they attempt to assign an interface to the mgmt_junos routing instance, which is not necessary for isolating management traffic1.


問題 #68
You must implement filter-based forwarding. You need to direct traffic from the 192.168.1.0/24 through vr1 and traffic from 10.210.0.128/26 through vr2.
Which configuration is correct in this scenario?

答案：C


問題 #69
Which two statements are correct about Junos OS "show ospf neighbor" command output showing a neighbor state of "2-Way"? (Choose two.)

答案：B,D

解題說明：
The 2-Way state in OSPF indicates that bidirectional communication has been established, meaning each router has seen itself listed in the neighbor's hello packets. On a broadcast multi- access network, routers that are not the DR or BDR (referred to as DROthers) typically remain in the 2-Way state with each other, since full adjacency and database synchronization only occurs between DROthers and the DR/BDR, not between DROthers themselves.


問題 #70
Your GRE tunnel is not transitioning to the Up status.
What would be the first step in troubleshooting the problem?

答案：D


問題 #71
......
