Juniper Data Center, Associate (JNCIA-DC) Sample Questions (Q152-Q157):

NEW QUESTION # 152
Which statement is correct about OSPF?

  • A. OSPF is a path-vector protocol
  • B. OSPF is link-state protocol
  • C. OSPF is a device-state protocol
  • D. OSPF is a distance-vector protocol

Answer: B


NEW QUESTION # 153
What is the primary purpose of using aggregate routes in a network?

  • A. To summarize and reduce the number of routes in the routing table
  • B. To filter unwanted traffic
  • C. To dynamically adjust to network changes
  • D. To statically define a route to a specific destination

Answer: A


NEW QUESTION # 154
What are two consequences of having all network devices in a single collision domain? (Choose two.)

  • A. The chance of packet collision is decreased.
  • B. The chance of packet collision is increased.
  • C. The amount of network resource consumption does not change.
  • D. The amount of network resource consumption is increased.

Answer: B,D

Explanation:
Acollision domainis a network segment where data packets can "collide" with one another when being sent on the same network medium.
Step-by-Step Breakdown:
* Increased Collision Probability:If all devices are in asingle collision domain, the likelihood of packet collisions increases as more devices attempt to send packets simultaneously, leading to network inefficiencies.
* Increased Resource Consumption:More collisions result inincreased network resource consumption as devices need to retransmit packets, causing higher utilization of bandwidth and slowing down network performance.
Juniper Reference:
* Collision Domains: Proper network segmentation using switches reduces collision domains, thereby improving network performance and reducing packet collisions.


NEW QUESTION # 155
What happens if a frame with a known destination MAC address enters a switch?

  • A. The egress PFE performs a MAC address lookup and determines the ingress PFE and port.
  • B. The ingress PFE sends the header information to the RE.
  • C. The MAC address is added to the bridge table.
  • D. The ingress PFE performs a MAC address lookup and determines the egress PFE and port.

Answer: D


NEW QUESTION # 156
What information in the Ethernet header is used to populate the bridging table?

  • A. type
  • B. protocol
  • C. destination address
  • D. source address

Answer: D

Explanation:
Thesource MAC addressin the Ethernet header is used to populate thebridging table(also called the MAC address table) on a switch. When a frame arrives at a switch, the switch examines the source MAC address and records it along with the ingress port in its MAC address table.
Step-by-Step Breakdown:
* Learning Process:When an Ethernet frame arrives on a switch port, the switch looks at thesource MAC addressand adds this MAC address to the MAC table along with the port it was received on.
This process is calledMAC learning.
* Purpose:The switch uses this information to determine the correct port to send frames destined for that MAC address in future transmissions, thus ensuring efficient Layer 2 forwarding.
Juniper Reference:
* Ethernet Switching: Juniper switches use source MAC addresses to build and maintain the MAC address table, which is essential for Layer 2 switching.
