Many candidates find the Juniper JN0-281 exam preparation difficult. They often buy expensive study courses to start their Data Center, Associate (JNCIA-DC) JN0-281 certification exam preparation. However, spending a huge amount on such resources is difficult for many Data Center, Associate (JNCIA-DC) JN0-281 Exam applicants.

Juniper JN0-281 Exam Syllabus Topics:

TopicDetails
Topic 1
  • Layer 2 Switching and VLANs: This section of the exam measuresthe skills of a Network Support Engineer and covers the essential concepts of Layer 2 switching operations within Junos OS. It includes an overview of Ethernet switching and bridging, providing an understanding of how Layer 2 networks function. The section also introduces VLAN concepts, focusing on port modes, VLAN tagging methods, and the purpose of Integrated Routing and Bridging (IRB). It further explores the practical side by addressing how to configure, monitor, and troubleshoot both Layer 2 switching and VLANs.
Topic 2
  • Protocol-Independent Routing: This section of the exam measures the skills of a Routing Engineer and covers routing features that function independently of any specific protocol. It includes static, aggregate, and generated routes, along with the concept of martian addresses. Routing instances and Routing Information Base (RIB) groups are introduced, as well as techniques like load balancing and filter-based forwarding. Configuration, monitoring, and troubleshooting aspects of these routing components are also covered in this section.
Topic 3
  • High Availability: This section of the exam measures the skills of a Data Center Reliability Engineer and covers strategies to ensure continuous network availability. It includes features like Link Aggregation Groups (LAG), Graceful Restart (GR), Bidirectional Forwarding Detection (BFD), and Virtual Chassis. It also provides a basic understanding of how to configure, monitor, and troubleshoot each of these high-availability components to maintain resilient network performance.
Topic 4
  • Data Center Routing Protocols BGP
  • OSPF: This section of the exam measures skills of a Network Operations Specialist and covers the operation and key concepts of the OSPF protocol. It explains elements such as the link-state database, OSPF packet types, and router IDs, including how adjacencies and designated routers work within areas. The section then transitions to BGP, outlining its basic operations, message types, attributes, and the path selection process. It also discusses both IBGP and EBGP roles. Lastly, the section reviews how to configure, monitor, and troubleshoot OSPF and BGP using routing policies and various tools.
Topic 5
  • Data Center Architectures: This section of the exam measures the skills of a Data Center Architect and covers foundational knowledge about various data center designs. It includes traditional multitier architectures as well as more modern IP fabric architectures using spine-leaf topologies. The section also touches on Layer 2 and Layer 3 strategies for forwarding traffic, the differences between overlay and underlay networks, and introduces Ethernet VPN–Virtual Extensible LAN (EVPN-VXLAN), explaining its basic purpose and role in data center environments.

Juniper Data Center, Associate (JNCIA-DC) Sample Questions (Q110-Q115):

NEW QUESTION # 110
Exhibit:

R2 received an OSPF update from R1, and it received the same update from R3.
Referring to the exhibit, what will R2 do?

  • A. R2 does nothing with R3's update.
  • B. R2 ignores the update from R3.
  • C. R2 ignores the update from R1.
  • D. R2 acknowledges R3 and discards it.

Answer: B

Explanation:
In the exhibit, R2 receives the same OSPF update from both R1 and R3. OSPF has mechanisms to prevent unnecessary processing of duplicate LSAs (Link-State Advertisements).
Step-by-Step Breakdown:
OSPF LSA Processing:
OSPF uses LSAs to exchange link-state information between routers. When a router receives an LSA, it checks if it already has a copy of the LSA in its Link-State Database (LSDB).
Duplicate LSAs:
If R2 has already received and processed the update from R1, it will ignore the update from R3 because it already has the same LSA in its database. OSPF uses the concept of flooding, but it does not reprocess LSAs that it already knows about.
R2 Behavior:
R2 will keep the update from R1 (the first one it received) and will ignore the same LSA from R3, as it is already in the LSDB.
Juniper Reference:
OSPF LSA Processing: Junos adheres to OSPF standards, ensuring that duplicate LSAs are not processed multiple times to avoid unnecessary recalculations.


NEW QUESTION # 111
When a MAC limiting violation occurs, the switch performs which two actions by default? (Choose two.)

  • A. It causes Layer 2 loops.
  • B. It drops the packet.
  • C. The port is disabled.
  • D. No logging takes place.

Answer: B,C

Explanation:
When a MAC limiting violation occurs on a Juniper switch, the switch will perform the following actions by default:
Step-by-Step Breakdown:
Port Disabled:
When the number of MAC addresses on an interface exceeds the configured limit, the port is automatically disabled to prevent further violations. This is a protective mechanism to prevent MAC address flooding.
Packet Dropped:
Additionally, packets from the violating MAC address are dropped to prevent any further communication from that address. This ensures that only valid MAC addresses are allowed to communicate through the interface.
Example Configuration:
set ethernet-switching-options secure-access-port interface <interface-name> mac-limit 5 If more than five MAC addresses are learned, the port is disabled, and excess packets are dropped.
Juniper
Reference: MAC Limiting: When the switch detects a MAC limiting violation, it disables the port and drops further packets from the violating MAC addresses to maintain network security.


NEW QUESTION # 112
In Ethernet switching, what is the primary function of a storm control policy?

  • A. To filter MAC addresses.
  • B. To prevent loops in the network.
  • C. To restrict the rate of certain types of traffic.
  • D. To segregate broadcast domains.

Answer: C


NEW QUESTION # 113
EVPN/VXLAN is primarily used in modern data centers to:

  • A. Replace traditional routing protocols.
  • B. Enhance the physical security of the data center.
  • C. Provide Layer 2 connectivity over a Layer 3 network.
  • D. Increase the physical distance between data centers.

Answer: C


NEW QUESTION # 114
Referring to the exhibit, how many collision domains are present in the topology?

  • A. 0
  • B. 1
  • C. 2
  • D. 3

Answer: D
