Sample Questions For the JN0 351 Exam

Here are some demo questions to help you make an informed decision:

Which two events cause a router to advertise a connected network to OSPF neighbors? (Choose two.)
Option A :
When an OSPF adjacency is established.
Option B :
When an interface has the OSPF passive option enabled.
Option C :
When a static route to the address is created.
Option D :
When a static route to the address is created.
Correct Answer: A,D
A is correct because when an OSPF adjacency is established, a router will advertise a connected network to OSPF neighbors. An OSPF adjacency is a logical relationship between two routers that agree to exchange routing information using the OSPF protocol1. To establish an OSPF adjacency, the routers must be in the same area, have compatible parameters, and exchange hello packets1. Once an OSPF adjacency is formed, the routers will exchange database description (DBD) packets, which contain summaries of their link-state databases (LSDBs)1. The LSDBs include information about the connected networks and their costs2.
Therefore, when an OSPF adjacency is established, a router will advertise a connected network to OSPF neighbors through DBD packets. D is correct because when a static route to the address is created, a router will advertise a connected network to OSPF neighbors. The address is the multicast address for all OSPF routers3. A static route to this address can be used to send OSPF hello packets to all OSPF neighbors on a network segment3. This can be useful when the network segment does not support multicast or when the router does not have an IP address on the segment3. When a static route to the address is created, the router will send hello packets to this address and establish OSPF adjacencies with other routers on the segment3. As explained above, once an OSPF adjacency is formed, the router will advertise a connected network to OSPF neighbors through DBD packets.
What is the default MAC age-out timer on an EX Series switch?
Option A :
30 minutes
Option B :
30 seconds
Option C :
300 minutes
Option D :
300 seconds
Correct Answer: D
The default MAC age-out timer on an EX Series switch is 300 seconds12. The MAC age-out timer is the maximum time that an entry can remain in the MAC table before itœages out, or is removed31. This configuration can influence efficiency of network resource use by affecting the amount of traffic that is flooded to all interfaces1. When traffic is received for MAC addresses no longer in the Ethernet routing table, the router floods the traffic to all interfaces1.
Which two statements are true about the default VLAN on Juniper switches? (Choose two.)
Option A :
The default VLAN is set to a VLAN ID of 1 by default
Option B :
The default VLAN ID is not assigned to any interface.
Option C :
The default VLAN ID is not visible.
Option D :
The default VLAN ID can be changed.
Correct Answer: A,D
On Juniper switches, the default VLAN is set to a VLAN ID of 1 by default12. This means that all interfaces on the switch are members of VLAN 1 until they are specifically assigned to another VLAN12. Therefore, option A is correct.
The default VLAN ID can be changed12. This allows network administrators to configure the switch to use a different VLAN as the default, if necessary12. Therefore, option D is correct.
You are configuring an IS-IS IGP network and do not see the IS-IS adjacencies established. In this scenario, what are two reasons for this problem? (Choose two.)
Option A :
MTU is not at least 1492 bytes.
Option B :
IP subnets are not a /30 address.
Option C :
The Level 2 routers have mismatched areas.
Option D :
The lo0 interface is not included as an IS-IS interface.
Correct Answer: A,D
Option A suggests that the MTU is not at least 1492 bytes. This is correct because IS-IS requires a minimum MTU of 1492 bytes to establish adjacencies1. If the MTU is less than this, IS-IS adjacencies will not be established1.
Option D suggests that the lo0 interface is not included as an IS-IS interface. This is also correct because the loopback interface (lo0) is typically used as the router ID in IS-IS1. If the loopback interface is not included in IS-IS, it could prevent IS-IS adjacencies from being established1.
Therefore, options A and D are correct.
