Juniper Data Center, Associate (JNCIA-DC) Sample Questions (Q83-Q88):

NEW QUESTION # 83
Generated routes in a network are mainly used to:

  • A. Automatically create a route when a specified condition is met.
  • B. Reduce the overall size of the routing table.
  • C. Manually configure specific network routes.
  • D. Summarize external routes into the network.

Answer: A


NEW QUESTION # 84
What are two device roles in a five-member Virtual Chassis? (Choose two.)

  • A. Routing-engine
  • B. PFE
  • C. Control-board
  • D. Line card

Answer: A,D

Explanation:
In aVirtual Chassis(VC) configuration, multiple Juniper switches are interconnected to form a single logical device. Each member switch in the Virtual Chassis plays a specific role.
Step-by-Step Breakdown:
* Line Card Role:
* Member switches acting asline cardsprovide additional ports for traffic forwarding but do not perform control or routing functions. These switches depend on the routing engine to handle control-plane tasks.
* Routing Engine Role:
* A switch in therouting-enginerole is responsible for control-plane operations such as routing protocol management and control of the Virtual Chassis.
* Virtual Chassis Roles:
* Master Routing Engine: Handles control-plane functions and manages the entire Virtual Chassis.
* Backup Routing Engine: Takes over if the master fails.
* Line Card: Provides additional ports and handles data-plane operations.
Juniper Reference:
* Virtual Chassis: In a five-member Virtual Chassis, multiple switches act asline cards, while one or more switches are designated as therouting engines(master and backup).


NEW QUESTION # 85
What is the main advantage of using MACsec?

  • A. It increases the speed of the network.
  • B. It creates multiple virtual networks over a single physical infrastructure.
  • C. It allows for the use of longer cable runs.
  • D. It provides Layer 2 encryption for data confidentiality and integrity.

Answer: D


NEW QUESTION # 86
Which two statements are correct about VLAN tags? (Choose two.)

  • A. VLAN tags require multiple forwarding tables.
  • B. VLAN tags are required on access ports.
  • C. VLAN tags carry a VLAN ID and priority.
  • D. VLAN tags can be inserted or removed by trunk interfaces.

Answer: C,D

Explanation:
VLAN tagsare used in Ethernet frames to identify and differentiate traffic between multiple VLANs. They are especially important for devices like switches that handle multiple VLANs on the same physical link.
Step-by-Step Breakdown:
* VLAN Tag Contents:
* VLAN ID: The tag contains a 12-bit VLAN ID field that identifies the VLAN to which the frame belongs.
* Priority: The tag also includes a 3-bit priority field (also known as 802.1p priority) used for QoS (Quality of Service) to prioritize traffic.
* Trunk Ports and VLAN Tagging:
* Trunk Portsare used to carry traffic for multiple VLANs across a single link. These interfaces insert (tag) VLAN identifiers into frames when they leave the switch and remove (untag) them when frames enter the switch.
* Access Ports:VLAN tags are typically not used onaccess ports(ports that connect to end devices) since those ports are configured to be part of a single VLAN, and the traffic doesn't need VLAN tags.
Juniper Reference:
* VLAN Tagging: Juniper switches support VLAN tagging and ensure that frames are tagged or untagged as they traverse trunk or access ports, respectively.


NEW QUESTION # 87
In a Virtual Chassis configuration, which of the following is true?

  • A. It decreases network redundancy and reliability.
  • B. It allows physical stacking of switches that are geographically dispersed.
  • C. It reduces the operational complexity of managing multiple switches.
  • D. Only two switches can be connected in a Virtual Chassis setup.

Answer: C
