Question 51

Report Export Collapse

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

OSPF metric value
OSPF metric value
next hop IP address
next hop IP address
BGP local preference value
BGP local preference value
outgoing interface name
outgoing interface name
next hop MAC address
next hop MAC address
Suggested answer: B, D, 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.

Exhibit.

Juniper JN0-105 image Question 52 49964 09182024210934000000

Referring to the exhibit, which routing configuration is required for these two users to access the remote server?

Users must connect directly to the router.
Users must connect directly to the router.
Users and the server require a default gateway.
Users and the server require a default gateway.
Trunk ports must be enabled on the switch.
Trunk ports must be enabled on the switch.
A routing protocol must be enabled on the router.
A routing protocol must be enabled on the router.
Suggested answer: B
Explanation:

For the users in the 10.1.1.0/24 subnet and the server in the 10.1.2.0/24 subnet to communicate with each other, they need to route packets through the router that connects these two subnets. Each user and the server need to have their default gateway set to the IP address of the router interface on their respective subnet (.254). This ensures that packets destined for other subnets are sent to the router, which then routes them to the correct destination subnet.

Question 53

Report Export Collapse

Which process in the Junos OS is responsible for maintaining routing protocols and tables?

mgd
mgd
chassisd
chassisd
rpd
rpd
dcd
dcd
Suggested answer: C
Explanation:

The Routing Protocol Daemon (rpd) in Junos OS is responsible for maintaining routing protocols and tables. It handles all routing information, including the calculation of routes and the population of the routing table, making it crucial for dynamic routing operations.

Question 54

Report Export Collapse

Which Junos OS component is responsible for maintaining the forwarding table?

Routing Engine
Routing Engine
chassis control daemon
chassis control daemon
Packet Forwarding Engine
Packet Forwarding Engine
management daemon
management daemon
Suggested answer: C
Explanation:

The Packet Forwarding Engine (PFE) in Junos OS is responsible for maintaining the forwarding table. The PFE processes incoming packets, performs route lookups in the forwarding table, and forwards packets based on this information, offloading these tasks from the Routing Engine to ensure efficient packet forwarding.

Question 55

Report Export Collapse

Which two common routing policy actions affect the flow of policy evaluation? (Choose two.)

next policy
next policy
community
community
next term
next term
next hop
next hop
Suggested 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 56

Report Export Collapse

Which criteria does the Junos OS use to select an active route when two entries exist in the routing table?

the route with the lowest preference number
the route with the lowest preference number
the most recently learned dynamic route
the most recently learned dynamic route
the route with the highest preference number
the route with the highest preference number
the route with the highest metric
the route with the highest metric
Suggested answer: A
Explanation:

In Junos OS, when two entries for the same destination exist in the routing table, the route with the lowest preference number is selected as the active route. This preference number, also known as the route preference or administrative distance, is used to prioritize routes received from different routing protocols.

How many rescue configuration files are supported on a Junos device?

3
1
1
49
49
Suggested answer: C
Explanation:

Junos OS supports only 1 rescue configuration file on a device. This rescue configuration is a safeguard feature that allows network administrators to revert to a known good configuration in case of a configuration error or issue, ensuring network stability.

In Junos OS, each device supports only one rescue configuration file. The rescue configuration is a specific configuration that can be saved and later retrieved if needed. This is used as a fallback configuration that you know works and can be applied in case of an emergency or if the current configuration has issues.

'You can create a rescue configuration file by using the request system configuration rescue save operational mode command. Each Junos OS device can have only one rescue configuration file.'

Question 58

Report Export Collapse

Which two functions are performed by the PFE? (Choose two.)

It implements firewall filters.
It implements firewall filters.
It selects active routes.
It selects active routes.
It forwards transit traffic.
It forwards transit traffic.
It maintains the routing table.
It maintains the routing table.
Suggested answer: A, C
Explanation:

The Packet Forwarding Engine (PFE) in Junos OS performs several key functions, including implementing firewall filters (A) and forwarding transit traffic (C). The PFE applies firewall filter rules to incoming and outgoing traffic and is responsible for the high-speed forwarding of packets based on the information in the forwarding table.

What are two physical interface properties? (Choose two.)

MAC address
MAC address
IP address
IP address
routing protocols
routing protocols
MTU
MTU
Suggested answer: A, D
Explanation:

Two physical interface properties in Junos OS include the MAC address (A) and the Maximum Transmission Unit (MTU) size (D). The MAC address is a hardware identifier for the network interface, while the MTU size determines the largest packet size that the interface can transmit without needing to fragment the packet.
