Juniper Junos, Associate (JNCIA-Junos) Sample Questions (Q17-Q22):

NEW QUESTION # 17
Which two statements are correct about firewall filters? (Choose two.)

A. "Discard" is the default action of packets that are not explicitly allowed.
B. "Accept" is the default action of packets that are not explicitly allowed.
C. There can be only one firewall filter.
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.

NEW QUESTION # 18
Which command modifier would you use to see all possible completions for a specific command?

A. extensive
B. detail
C. ?
D. |

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:
"Use the ? command modifier to display all possible completions for a specific command."

NEW QUESTION # 19
What information does the forwarding table require so that the device forwards traffic? (Choose three.)

A. next hop IP address
B. OSPF metric value
C. next hop MAC address
D. BGP local preference value
E. outgoing interface name

Answer: A,C,E

Explanation:
The forwarding table in a network device requires specific information to efficiently forward traffic toward its destination. This includes the next hop IP address, which indicates the next router or device in the path to the destination. The outgoing interface name identifies the physical or logical interface through which the packet should be sent to reach the next hop. Lastly, the next hop MAC address is crucial for Layer 2 forwarding decisions, allowing the device to encapsulate the IP packet in a frame that can be understood by Ethernet or other Layer 2 protocols. OSPF metric values and BGP local preference values are used in the routing decision process to select the best path and populate the forwarding table but are not directly used by the forwarding table to forward traffic.

NEW QUESTION # 20
You have configured some interfaces on a Junos device; however, you have not yet committed the configuration.
What happens if you issue the rollback 0 command in this scenario?

A. The Junos device is rebooted.
B. The interface changes you made are discarded.
C. The messages.log file is deleted.
D. The factory default configuration is loaded.

Answer: B

Explanation:
Issuing the rollback 0 command in Junos OS will discard any uncommitted changes and revert to the last committed configuration. This command effectively cancels any configuration changes that have been made but not yet committed, ensuring that the device returns to its previous stable state.
Reference:
"rollback 0 ...................................(rolls back the changes just made )" from Useful Juniper Commands.txt.
Juniper official documentation: Rolling Back a Configuration.

NEW QUESTION # 21
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 routing 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 forwarding table stores all routes and prefixes from all protocols.

Answer: A,B

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.
