Question 1

Which keystroke combination allows users to move the cursor to the end of the command line without deleting text?

Question 2

What is the purpose of the load merge command?

Accepted Answer

The load merge command is used to combine the current configuration with the configuration being loaded. It ensures that any existing configurations are not overwritten while adding new configurations from the loaded file.

Question 3

You issue the request system zeroize command. Which statement is correct in this scenario?

Accepted Answer

The request system zeroize command deletes all data files and returns all configuration settings to factory defaults. This command should be used with caution as it will erase all data and configurations on the device.

Question 4

You have configured an SRX Series device for the first time. When you commit your configuration, the Junos OS notifies you that you cannot yet commit your configuration. Which configuration step must you complete?

Accepted Answer

It is likely that the device requires root authentication to be configured before the configuration can be fully committed.

Question 5

What is the maximum number of configurations, by default, that are recoverable using the rollback command?

Accepted Answer

The default number of recoverable configurations is 50.

Question 6

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

Accepted Answer

C) MTU (Maximum Transmission Unit) is a configurable physical interface property that determines the largest packet size that can be transmitted over the network interface. MTU is typically set to a default value, but it can be adjusted to optimize network performance for specific applications or environments.

D) Link mode is a configurable physical interface property that determines how the network interface connects to other devices on the network. Link mode can be set to auto-negotiate, which allows the interface to automatically configure its connection settings based on the connection criteria of the connected device. Alternatively, link mode can be forced to a specific setting, such as full duplex or half duplex, to optimize network performance.

Protocol family and address are not configurable physical interface properties. Protocol family refers to the set of communication protocols used by the interface, and address refers to the physical or logical address assigned to the interface for network communication. While both properties can be configured, they are not physical interface properties.

Question 15

Which two conditions must exist in a Junos device for traffic to transit the device to a specific destination? (Choose two.)

Accepted Answer

In order for traffic to transit a Junos device to a specific destination, a routing table entry must exist in the device for that destination, and a forwarding table entry must also exist to forward traffic to that destination. Firewalls and routing policies may affect traffic flow, but they are not necessary conditions for traffic to transit to a specific destination.

Question 16

Which parameter would you use to prohibit the redistribution of a static route used for management traffic?

Accepted Answer

The "no-readvertise" parameter can be used to prohibit the redistribution of a static route. This tells the router not to advertise the static route to any other routers in its routing updates. The other options are not appropriate for this situation: 
- "discard" is used to discard packets that match a certain criteria, not for preventing redistribution of routes. 
- "passive" is used to prevent a router from sending routing updates out a specific interface. 
- "reject" is used in access control lists to block traffic, not for preventing redistribution of routes.

Question 18

What is the purpose of the discard action of a firewall filter?
