Question 1

Which two statements are correct about firewall filters in the Junos OS? (Choose two.)

Firewall filters are stateless.

Firewall filters are used to control routing information that is exchanged between devices.

Firewall filters are used to control traffic passing through the device.

Firewall filters can only be applied to traffic entering the device.

Question 2

You issue the command telnet interface ge-1/1/0 10.10.10.1 source 192.168.100.1 bypass- routing.
Which statement is correct?

The bypass-routing parameter is ignored when using private IP addressing.

The telnet session will have the source IP address 10.10.10.1.

The telnet session will connect to the neighboring device’s interface ge-1/1/0.

Return traffic for the telnet session might not arrive at interface ge-1/1/0.

Question 3

You have a network containing 120 routers. You must establish and maintain connectivity between the loopback interfaces of all routers. Because of the critical services using the network, you need redundancy and fast failover.
Which routing protocol should you use in this scenario?

OSPF

RIP

BGP

static

Question 4

-- Exhibit --
traceroute to 10.1.15.2 (10.1.15.2), 30 hops max, 40 byte packets
1 10.1.36.1 (10.1.36.1) 0.651 ms 7.834 ms 0.506 ms
2 10.1.23.1 (10.1.23.1) 0.5 ms 0.5 ms 0.5 ms
3 * * *
4 * * *
-- Exhibit --
Referring to the exhibit, which statement is correct?

The packets have exceeded the time-to-live value.

There is a loop.

The asterisks indicate a response time out.

The asterisks indicate that the traceroute is completed.

Question 5

You have configured logging to the console port but are uncertain of the impact to the device with troubleshooting.
In this scenario, which command would allow you to minimize the impact?

set system syslog console any none

set system syslog log-rotate-frequency 15

commit confirmed 1 comment troubleshoot

commit synchronize comment troubleshoot

Question 6

What are three advantages which dynamic routing protocols offer over static routing protocols? (Choose three.)

lower administrative overhead

increased network availability

greater network scalability

easier to implement qualified next hops

easier ECMP route implementation

Question 7

What is correct regarding the configuration shown below?
static route 0.0.0.0/0 qualified-next-hop 172.30.25.1 preference 7 next-hop 172.30.25.5

The next-hop 172.30.25.1 is selected because the address has the lowest value.

The next-hop 172.30.25.1 is selected because it is listed first.

The next-hop 172.30.25.1 is selected because it is the lowest protocol preference.

The next-hop 172.30.25.5 is selected because it is the lowest protocol preference.

Question 8

What is an advantage of multiple software processes running in the Junos OS?

Each process has its own protected memory space.

Each process is started manually by the user at boot.

All processes are dependent on each other.

Multiple processes allow each routing protocol to be independent.

Question 9

You are at the top of the hierarchy and must configure OSPF on interface so-0/0/0 unit 100. Which two achieve this result? (Choose two.)

set protocolssetospf area 0set interface so-0/0/0.100

set protocols ospf area 0 interface so-0/0/0.100

edit protocols ospf interface so-0/0/0.100

edit protocols ospf area 0set interface so-0/0/0.100

Question 10

Which two statements describe the forwarding table in the Junos OS? (Choose two.)

The forwarding table contains all known routes.

The forwarding table stores a subset of information from the routing table.

Junos devices use the forwarding table to compare incoming packets against existing entries to determine the next hop.

If multiple matches exist, the forwarding table uses the least-specific entry to forward packets toward the destination.

Question 11

Which command do you use as a valid way to view the PICs within a router as well as the PICs' serial numbers?

show chassis hardware

show chassis interfaces

show chassis pic

show chassis inventory

Question 12

Which command will allow you to quickly determine the administrative status of all interfaces on a Junos device?

show interfaces status

show interfaces summary

show interfaces terse

show interfaces admin

Question 13

Which command is used to load the rescue configuration?

load override rescue

rollback rescue

load replace rescue-configuration

rollback 49

Question 14

Why is IPv6 packet processing more effective than IPv4 packet processing?

fixed header size

smaller header size

fewer header fields

variable header size

Question 15

Which two statements describe the default behavior for OSPF? (Chosoe two.)

OSPF imports all routes into the inet.0 routing table.

OSPF exports all static routes into the OSPF database.

OSPF does not export static routes into the OSPF database.

OSPF imports all routes into the inet4.0 routing table.

Question 16

Click the exhibit button.
JN0-102 dumps exhibit

Which statement is correct regarding the configuration shown in the exhibit?

When the ospf-trace file has created five files, it will stop logging additional information.

When the ospf-trace file reaches the 64 KB file size, it is renamed and begins a new file.

Timestamp information will not be included for each line of ospf-trace output.

The ospf-trace file will automatically replace any existing trace file with the same name.

Question 17

Which two login-class permissions could permit a user to view the system hierarchy of the active configuration? (Choose two.)

system permission

view-configuration permission

network permission

super-user permission

Question 18

Which three statements are true regarding the candidate configuration? (Choose three.)

The candidate configuration is a temporary configuration that might become the active configuration.

A candidate configuration is initially populated with the configuration currently active on the system.

Changes to the candidate configuration take effect immediately.

The candidate configuration becomes the active configuration after a system reboot.

The configure private command allows concurrent editing of a candidate configuration by multiple users.

Question 19

Which command do you use to display the messages seen during the last system boot?

show system boot-messages

show chassis messages

show file system boot-messages

show boot-log messages

Question 20

Which statement is correct about logical units on Juniper Router interfaces?

Logical units are used only when a Layer 2 identifier is present such as a VLAN.

A logical unit of 0 is required when using a frame-relay DLCI.

A logical unit is always required.

Logical units are not required unless ATM or 802.1Q VLAN tagging is configured.

Question 21

You recently uploaded a new software package to your Junos device and you want to ensure that the file uploaded successfully by verifying the file size.
In this scenario, which command should you use?

file show encoding

file compare

file checksum sha1

file list detail

Question 22

How do you write the current candidate configuration to the permanent storage media?

[edit]user@router# save /var/tmp/current.conf

[edit]user@router# write /var/tmp/current.conf

[edit]user@router# commit /var/tmp/current.conf

[edit]user@router# dump /var/tmp/current.conf

Question 23

Which set of IP addresses are in the same subnet?

185.114.16.59/28 and 185.114.16.64/28

185.114.16.91/28 and 185.114.16.96/28

185.114.16.77/28 and 185.114.16.82/28

185.114.16.40/28 and 185.114.16.45/28

Question 24

You issue the ping interface t1-1/1/0 1.1.1.1 bypass-routing count 1000 rapid command. Which statement is correct?

The bypass-routing parameter is used to test the density on the T1 line.

The bypass-routing parameter cannot be used on a T1 interface.

The bypass-routing parameter allows you to ping a host through an interface that has no route through it.

The bypass-routing parameter allows you to ping a local WAN interface without generating any outbound traffic.
