Juniper JN0-105 Sample Question Answers
Question # 1
You want to redeploy a Junos device by clearing the existing configuration and resetting it to factory defaults.In this scenario, which command would help to accomplish this task?
A. show system storage B. request systemstorage cleanup C. request systemstorage cleanup dry-run D. request systemzeroize media
Answer: D
Explanation: The request system zeroize media command on a Junos device securely
erases all data, including configuration and log files, and resets the device to its factory
default settings. This command is used when redeploying a device to ensure no residual
data remains from its previous deployment. It's a comprehensive and secure way to clear
all configurations and data, making the device as if it were new. The other commands listed
do not perform a full reset to factory defaults; for example, show system storage displays
storage information, and request system storage cleanup offers to delete unnecessary
files without resetting the device to factory settings.
Question # 2
You issue the telnet 10.10.10.1 source 192.168.100.1 command.Which two statements are correct in this scenario? (Choose two.)
A. The telnet session will have a source address of 10.10.10.1. B. The telnet session will have a destination address of 192.168.100.1. C. The telnet session will have a destination address of 10.10.10.1. D. The telnet session will have a source address of 192.168.100.1.
Answer: C,D
Explanation: In the given telnet command, "telnet 10.10.10.1 source 192.168.100.1," the
destination address of the telnet session is 10.10.10.1, and the source address of the
session is specified as 192.168.100.1, making C and D the correct answers. This
command instructs the telnet client to use the specified source IP address when
establishing the connection to the destination.
Question # 3
You have logged on to a Junos device and are at the operational mode prompt.Which two commands are used at this prompt? (Choose two.)
A. show interface ge-0/0/0 B. request system shutdown C. set interface ge-0/0/0 unit 0 family inet D. run show interface terse
Answer: A
Explanation: At the operational mode prompt on a Junos device, you can use various
commands to view the device's status and request system operations. The show interface
ge-0/0/0 command is used to display information about a specific interface, while the
request system shutdown command is used to properly shut down the device. The set
command is used in configuration mode, not operational mode, and the run command is
used to execute operational mode commands from configuration mode.
Question # 4
Exhibituser@router> show route 192.168.100.2inet.O: 15 destinations, 17 routes (15 active, 0 holddown, 0 hidden) Limit/Threshold:1048576/1048576 destinations+ = Active Route, - = Last Active, * = Both 192.168.100.2/32*[OSPF/IO] 00:14:29, metric 1> to 172.16.1.6 via ge-0/0/1.0 [BGP/170] 00:06:49, localpref 100AS path: 65102 I, validation-state: unverified > to 172.16.1.6 via ge-0/0/1.0Referring to the exhibit, which statement is correct?
A. The BGP path is the only active route. B. The BGP route is preferred over the OSPF route. C. The OSPF path is the only active route. D. / Traffic is load-balanced across two routes.
Answer: C
Explanation: Referring to the exhibit, the presence of the "+" symbol next to the OSPF
route for 192.168.100.2/32 indicates that this is the active route being used to forward
traffic. The BGP route, although present, does not have the "+" symbol, indicating it is not
the active route. In Junos OS, the routing table displays the active route with a "+" symbol,
and the fact that the OSPF route has this symbol means it is the preferred path based on
the routing protocol's decision process, which takes into account factors such as route
preference (administrative distance) and metrics.
Question # 5
What are two functions of the Routing Engine? (Choose two.)
A. It processes all management traffic. B. It runs the Junos operating system. C. It evaluates firewall filters for transit traffic. D. It processes transit traffic.
Answer: A,B
Explanation: The Routing Engine (RE) in Junos OS has several critical functions,
including processing all management traffic (A) and running the Junos operating system (B). The RE handles system management tasks, user interfaces, system services, and
routing protocol processes. It does not directly process transit traffic or evaluate firewall
filters for transit traffic, as these tasks are handled by the Packet Forwarding Engine (PFE).
Question # 6
What is the primary system log file that is present in the default configuration of a Junosdevice?
A. kmd B. messages C. vrrp D. jsrpd
Answer: B
Explanation: In the default configuration of a Junos device, the primary system log file is
"messages" (B). This log file contains a wide range of system messages, including
operational status changes, system errors, and other critical information, making it a key
resource for troubleshooting and monitoring the system's health.
Question # 7
Which command modifier would you use to see all possible completions for a specificcommand?
A. | B. detail C. ? D. extensive
Answer: C
Explanation: In Junos OS, the ? command modifier is used to display all possible
completions for a specific command. This helps users understand the available options and
syntax for a command they are trying to use.
Reference: Juniper Networks CLI Documentation
"Use the ? command modifier to display all possible completions for a specific command."
Question # 8
Which two statements are correct about the empioyee@Ri> prompt? (Choose two.)
A. R1 is the hostname of your device. B. You are in operational mode. C. You are in configuration mode. D. You are at a shell prompt.
Answer: A,B
Explanation: In Junos OS, the prompt employee@R1> indicates the current context of the
user interface. The 'R1' part of the prompt signifies the hostname of the device, which in
this case is 'R1'. The absence of a '#' symbol at the end of the prompt suggests that the
user is in operational mode, as opposed to configuration mode which is indicated by a
prompt ending in '#'. Operational mode allows users to view the status of the device and
execute operational commands, but does not allow for configuration changes.
Question # 9
An administrator configures a router's interface with an IPv4 address and subnet mask.The administrator also confirms that this interface is in an up state.In this scenario, which two route types are created on the local router? (Choose two.)
A. a static route B. a local route C. a dynamic route D. a direct route
Answer: B,D
Explanation: When an interface on a router is configured with an IPv4 address and is in an
up state, two types of routes are automatically created in the routing table: a local route and
a direct route, making B and D the correct answers. The local route represents the
interface's IP address itself, indicating that the router can directly receive packets
addressed to this IP. The direct route represents the subnet or network segment to which
the interface is connected, indicating that the router can directly forward packets to
destinations within this subnet.
Question # 10
Which two common routing policy actions affect the flow of policy evaluation? (Choosetwo.)
A. next policy B. community C. next term D. next hop
Answer: A,C
Explanation: In Junos OS routing policy evaluation, "next policy" (A) and "next term" (C)
are common actions that affect the flow of policy evaluation. "Next policy" directs the
evaluation to the next policy in the sequence, whereas "next term" moves the evaluation to
the next term within the current policy, allowing for granular control over routing decisions.
Question # 11
What information would you find using the CLI help command?
A. hyperlinks for remediation actions B. a URL for accessing the technical documentation C. an explanation for specific system log error messages D. message of the day
Answer: C
Explanation: The CLI help command in Junos OS provides assistance and explanations
for commands, command options, and in some cases, specific system log error messages.
By using the help command followed by specific keywords or messages, users can get
detailed information and context for the commands they are using or errors they are
encountering. This feature is particularly useful for understanding the purpose of
commands, their syntax, and troubleshooting error messages that may appear in system
logs.
Question # 12
Which protocol would you configure to synchronize the time and date on a Junos device?
A. SNMP B. RIP C. NTP D. NMP
Answer: C
Explanation: The Network Time Protocol (NTP) is designed to synchronize the clocks of
computers over a network. Configuring NTP on a Junos device ensures that its clock is set
accurately, which is crucial for logging, troubleshooting, and maintaining the integrity of
time-sensitive operations and security protocols. NTP allows devices to use a hierarchy of
time sources, from primary servers synchronized to a reference clock (such as an atomic
clock or GPS time) to secondary servers that distribute the time to other devices on the
network.
Question # 13
When considering routing tables and forwarding tables, which two statements are correct?(Choose two.)
A. The routing table is used by the RE to select the best route. B. The forwarding table stores all routes and prefixes from all protocols. C. The forwarding table is used by the RE to select the best route. D. The routing table stores all routes and prefixes from all protocols.
Answer: A,D
Explanation:
The routing table and forwarding table play distinct roles in a Junos OS device. The correct
answers are A and D. The routing table (A) is used by the Routing Engine (RE) to select
the best route among all the learned routes, while the routing table (D) stores all routes and
prefixes learned from all routing protocols. The forwarding table, in contrast, contains only
the active routes chosen by the RE and is used by the Packet Forwarding Engine for actual
packet forwarding.
Question # 14
Which two statements are true about the Junos OS? (Choose two.)
A. Routing tables are stored in the control plane. B. Exception traffic is never sent to the control plane. C. Exception traffic is sent to the control plane. D. Routing tables are stored in the forwarding plane.
Answer: A,C
Explanation: In Junos OS, as with many network operating systems, the control plane is
responsible for processes that determine how to route traffic. This includes maintaining
routing tables, which store information about network paths and protocols. Therefore,
routing tables are indeed stored in the control plane.
Exception traffic refers to packets that cannot be processed by the normal fast-path
processing of the Packet Forwarding Engine (PFE) in the forwarding plane, and thus are
sent to the control plane for further processing. This might include packets destined for the
router itself, packets that need to be fragmented, or packets that match certain firewall filter
criteria, among other reasons.
Routing tables are not stored in the forwarding plane. However, the forwarding plane
contains the forwarding table (sometimes referred to as the forwarding information base or
FIB), which is a distilled version of the routing table optimized for fast packet forwarding.
The forwarding plane uses this information to perform the actual transfer of packets across
the network device interfaces.
Question # 15
You are trying to diagnose packet loss at interface ge-0/0/3. In this scenario, which command would help you view error statistics in real time?
A. show interface terse B. show interface ge-0/0/3 C. monitor interface traffic D. monitor interface ge-0/0/3
Answer: D
Explanation: The monitor interface ge-0/0/3 command is used in Junos OS to view realtime
statistics for a specific interface. This command helps in diagnosing issues like packet
loss by displaying real-time updates of traffic and error statistics for the specified interface
Question # 16
You need to recover the root password on a Junos router without losing the currentconfiguration settings.Which three statements describe what you should perform in this scenario? (Choosethree.)
A. Enter and commit the new root password. B. Load the factory-default configuration. C. Upgrade the Junos OS to the latest version. D. Hit the space bar and enter recovery when prompted. E. Use a console connection to reboot the device.
Answer: A,D,E
Explanation: To recover the root password on a Junos router without losing the
configuration, you should (A) enter and commit the new root password once you have
gained access to the system, (D) hit the space bar to interrupt the boot process and enter
recovery mode when prompted during the boot process, and (E) use a console connection
to reboot the device and access the bootloader prompt. These steps allow you to reset the
root password while preserving the existing configuration.
Question # 17
What are two types of transit traffic that traverse the forwarding plane of a Layer 3 router?(Choose two.)
A. unicast traffic B. multicast traffic C. exception traffic D. broadcast traffic
Answer: A,B
Explanation: Transit traffic that traverses the forwarding plane of a Layer 3 router includes
both unicast and multicast traffic types. Unicast traffic is directed from a single source to a
single destination, while multicast traffic is sent from one source to multiple destinations
that are part of a multicast group. These types of traffic are efficiently routed through the
network by leveraging the router's forwarding plane capabilities. Exception traffic, which
requires special handling by the control plane, and broadcast traffic, which is typically
limited to a single broadcast domain and not usually forwarded by Layer 3 routers, are not
considered standard types of transit traffic for the forwarding plane of a router.
Question # 18
What are two methods for navigating to configuration mode from an operational modeprompt? (Choose two.)
A. Use the edit command. B. Use the quit command. C. Use the exit command. D. Use the configure command.
Answer: A,D
Explanation: In Junos OS, to navigate from operational mode to configuration mode, you
can use either the edit or configure command. Both commands move the CLI from
operational mode, where you can view the state of the device, to configuration mode,
where you can make changes to the device's configuration.
Question # 19
Which three benefits occur when operating an interior gateway protocol (IGP) in an autonomous system (AS)? (Choose three.)
A. IGPs automatically distribute static routing information. B. IGPs determine the optimal paths for data transmission. C. IGPs learn prefixes in the global Internet's routing table. D. IGPs react very fast to network change. E. IGPs learn everything about the subnets and best paths within your network.
Answer: B,D,E
Explanation: Operating an Interior Gateway Protocol (IGP) within an Autonomous System
(AS) provides several benefits, including determining the optimal paths for data
transmission (B), reacting quickly to network changes (D), and learning all about the
subnets and best paths within the network (E). IGPs are designed to manage routing within
a single AS efficiently, adapting to changes and ensuring data is routed through the best
available paths.
Question # 20
Which two statements are correct about firewall filters? (Choose two.)
A. "Discard" is the default action of packets that are not explicitly allowed. B. There can be only one firewall filter. C. "Accept" is the default action of packets that are not explicitly allowed. D. There can be multiple firewall filters.
Answer: A,D
Explanation: In Juniper Networks devices, firewall filters are used to control packet flow
through the device. The default action for packets that do not match any of the specified
criteria in the firewall filter is to discard them, enhancing network security by ensuring that
only explicitly allowed traffic can pass through. Furthermore, it is possible to configure
multiple firewall filters on a device, allowing for granular control over traffic based on
various criteria such as source, destination, and protocol type.
Question # 21
Which two components are included in a transport header? (Choose two.)
A. destination port number B. source MAC address C. source port number D. destination MAC address
Answer: A,C
Explanation: The transport layer in the OSI model is responsible for end-to-end
communication and error recovery. In a transport header, such as TCP or UDP, the key
components include the source port number and the destination port number. These port
numbers are used to identify sending and receiving applications. The source port number
indicates the port of the sending application, and the destination port number refers to the
port of the receiving application. MAC addresses, on the other hand, are part of the data
link layer (Layer 2) and would be included in an Ethernet header, not a transport header.
Question # 22

A. load factory-default B. set system root-authentication plain-text-password C. set system services ssh D. set system login idle-timeout 20
Answer: C
Explanation: In Junos OS, remote access to the device's CLI is commonly facilitated
through Secure Shell (SSH), a protocol providing secure command-line access over an
insecure network. The given exhibit indicates an attempt to set a root authentication
password but does not show configuration for enabling remote access services. To enable
SSH, which is not shown in the configuration snippet, you need to configure the device to
accept SSH connections. This is done by enabling the SSH service within the system
services hierarchy of the configuration. The correct command to add to the existing
configuration for enabling remote CLI access via SSH is set system services ssh. This
command activates the SSH service, allowing secure remote logins to the device.
Question # 23
You are creating a new policy to accept and redistribute routes into your IGP.In this scenario, which match criteria would you use to identify the route prefixes to select?
A. instance B. route-type C. neighbor D. route-filter
Answer: D
Explanation: When creating a new policy to accept and redistribute routes into your
Interior Gateway Protocol (IGP), the route-filter match criteria is used to identify the route
prefixes to select. The route-filter statement specifies which prefixes should be matched in
a policy. This allows for precise control over which routes are accepted and redistributed,
facilitating efficient and secure routing policies within the network.

Question # 24
What are two benefits when implementing class of service? (Choose two.)
A. The network will be faster. B. Traffic congestion can be managed. C. Traffic congestion will be eliminated. D. Latency-sensitive traffic can be prioritized
Answer: C,D
Explanation: Implementing Class of Service (CoS) in a network provides numerous
benefits, particularly in managing traffic based on its importance, source, or type. CoS
enables network administrators to manage traffic congestion by applying various queuing
techniques and policies to ensure that critical services remain unaffected during high
congestion periods. Additionally, CoS allows for the prioritization of latency-sensitive traffic
such as voice and video, ensuring that these services maintain quality despite varying
network conditions.
Question # 25
Which service does RADIUS provide?
A. routing B. authentication C. DNS resolution D. time synchronization
Answer: B
Explanation: RADIUS, which stands for Remote Authentication Dial-In User Service,
provides authentication services for users trying to access a network. It is a networking
protocol that provides centralized Authentication, Authorization, and Accounting (AAA)
management for users who connect and use a network service.
