Question 1

Your system administrator notified the infrastructure team that all server NICs will be moving to jumbo frames. All of the NICs used by servers are 1 gigabit. The starting frame size will be 4K. The exact frame size may change depending on testing results.
In this scenario, which choice would provide a flexible solution?
A. Create a group that adjusts MTU size on 1 gigabit interfaces and apply at the interfaces level.
B. Apply the MTU to each interface family for each 1 gigabit interface.
C. Set the app-engine compute-cluster Ethernet MTU size for the Junos VM.
D. Use the system internet-options path-mtu-discovery to dynamically adjust MTU.
Answer: A
Explanation: A configuration group lets the administrator define the MTU once and apply it to the relevant interfaces. If testing requires a different frame size, changing the group updates every interface that inherits the setting. Path MTU discovery does not configure the local interface to accept larger frames.

Question 2

Which statement about class of service (CoS) in a network is correct?
A. CoS encrypts traffic to secure data across the network.
B. CoS prioritizes certain types of traffic during congestion.
C. CoS assigns IP addresses dynamically to optimize routing.
D. CoS prevents broadcast storms by segmenting VLANs.
Answer: B
Explanation: CoS classifies traffic and uses queues and schedulers to give selected traffic priority when an interface is congested. It does not encrypt traffic, allocate IP addresses, or prevent Layer 2 loops.

Question 3

A network administrator must set up the initial configuration of the out-of-band management interface on a new Juniper router to ensure management traffic is isolated from the default routing table (inet.0).
In this scenario, which configuration step is required to accomplish this task in Junos OS?
A. Configure an IP address on interface ge-0/0/0.0 and enable ethernet-switching family.
B. Configure the lo0.0 loopback interface with a management IP and apply it to the [edit system services] hierarchy.
C. Assign an IP address to the me0.0 interface and set the routing-options to instance-type virtual-router.
D. Assign an IP address to interface fxp0.0 or em0.0 and use the command set system management-instance to enable the management routing instance.
Answer: D
Explanation: The set system management-instance command creates the dedicated mgmt_junos routing instance. Moving the management interface into that instance keeps management routes separate from the default inet.0 routing table.

Question 4

Which two tasks would you perform in operational mode? (Choose two.)
A. Requesting the system to reboot
B. Verifying the version of Junos OS
C. Committing your configuration
D. Rolling back to a previous configuration
Answer: A, B
Explanation: Operational mode is used to monitor the device and run system maintenance commands, including show version and request system reboot. Committing or rolling back a configuration requires configuration mode.

Question 5

Which two tasks are performed by the Routing Engine in a Junos device? (Choose two.)
A. The Routing Engine runs routing protocols.
B. The Routing Engine evaluates transit traffic against firewall filters.
C. The Routing Engine manages the device configuration.
D. The Routing Engine forwards transit traffic.
Answer: A, C
Explanation: The Routing Engine runs routing protocols and manages the Junos configuration database. The Packet Forwarding Engine handles transit packet forwarding and evaluates transit traffic against firewall filters.
