JNCIA-Junos JN0-105 Practice V.3

You enable unicast reverse path forwarding on the ge-0/0/1.0 interface A packet is received on the ge-0/0/1.0 interface with a source address of 10.10.10.10. A route lookup determines that the next hop for the 10.10.10.10 address is the ge-0/0/1.0 interface. In this scenario which action is performed?

• The packet is logged

• The packet is forwarded

• The packet is rejected

• The packet is discarded

Referring to the exhibit.

what happens when you issue the exit command at the [edit protocols ospf area 0.0.0.51 stub] hierarchy level?

• You move one level up to the [edit protocols ospf area 0.0.0.51] hierarchy level.

• You exit the configuration mode.

• You move to the [edit] hierarchy level.

• You move to the most recent higher level of the [edit protocols ospf] hierarchy.

Exhibit:

[edit routing-options]
user@router# show
static {
route 0.0.0.0/0 {
next-hop 10.1.1.1;
qualified-next-hop 10.1.1.254 {
preference 4;
}
}
}

Assuming both paths shown in the exhibit are available, which statement is correct?

• Traffic matching the default route will use 172.16.1.1 as the next hop

• Traffic matching the default route will use 172.16.1.254 as the next hop

• Traffic matching the default route will be load-balanced per flow across both next hops

• Traffic matching the default route will be load-balanced per packet across both next hops.

Which attribute must be defined when configunng a non-root user in Junos OS?

• class

• uid

• authentication

• full-name

Your Junos OS routers use a static route to provide connectivity to the management network. You do not want this static route to be redistributed using a dynamic routing protocol.

In this scenario, which static route configuration parameter will accomplish this task?

• no-install

• no-retain

• no-resolve

• no-readvertise

The user root is unable to connect to the router using SSH.
Referring to the exhibit, which configuration change will correct the problem?

• [edit] user@router# set system services ssh root-login allow

• [edit] user@router# set system services ssh

• [edit] user@router# delete system services ssh

• [edit] user@router# delete system services ssh root-login deny

After logging in as root, you enter the cli command.
What does this command do?

• It enables you to enter configuration mode.

• It enables you to enter line edit mode.

• It enables you to enter operational mode.

• It enables you to enter interface mode.

Referring to the exhibit, which two statements are true? (Choose two.)

• The logical interface is running IPv6.

• The interface is operating in full-duplex mode.

• The address 172.25.11.255 is the broadcast address for the logical interface.

• The interface MAC address has been changed from the default MAC address.

What happens if the packet shown in the exhibit is received by a device running Junos OS?

• The packet is received by the RE first and then redirected to the PFE

• The packet is received by the PFE first and then redirected to the RE

• The packet is handled by the PFE alone.

• The packet is handled by the RE alone.

Referring to the exhibit, which statement is correct about traffic received on the ge-0/0/1.0 interface?

• All traffic will be silently dropped.

• All traffic will be accepted.

• All traffic will be dropped and a UDP message sent back to the source.

• All traffic will be dropped and an ICMP notification sent back to the source.
