Juniper JN0-281 Exam Syllabus Topics:

TopicDetails
Topic 1
  • 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.
Topic 2
  • 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 3
  • 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 4
  • 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 5
  • 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.

Juniper Data Center, Associate (JNCIA-DC) Sample Questions (Q103-Q108):

NEW QUESTION # 103
Which statement is correct about an IP fabric?

  • A. The entire IP fabric is one large broadcast domain.
  • B. Loop prevention is provided by the underlying spanning tree protocol used.
  • C. Transit traffic is passed through the network based on the original frame's destination MAC address.
  • D. Load sharing is provided by the routing protocol used.

Answer: D


NEW QUESTION # 104
What are two common reasons for BGP routes to be in the hidden state? (Choose two.)

  • A. The BGP neighbor is in a different autonomous system
  • B. Routes are being filtered from the inet.2 routing table
  • C. Routes are being rejected by a policy
  • D. The next hop is unresolvable

Answer: C,D


NEW QUESTION # 105
Which two statements describe an OSPF ABR? (Choose two.)

  • A. By default, an ABR is an OSPF router with links in two areas.
  • B. By default, an ABR must have one link in the OSPF backbone area.
  • C. By default, an ABR does not need to have any links in the backbone area.
  • D. By default, an ABR is an OSPF router with all of its links in one area.

Answer: A,B


NEW QUESTION # 106
Referring to the exhibit, which statement is correct?

  • A. The ge-0/0/12 interfaces is an access port.
  • B. The asterisk indicates that the interface is active.
  • C. The ge-0/0/0 interface has been explicitly assigned to a VLAN named default.
  • D. The default VLAN is a user defined VLAN name.

Answer: B


NEW QUESTION # 107
Referring to the exhibit, you notice that after committing the configuration, the ae0 and ae1 interfaces appear in a link down state.

Which statement is correct in this scenario?

  • A. No operational interfaces have been added to the LAG interfaces.
  • B. The LAG interfaces are in aggressive mode.
  • C. No traffic is traversing the LAG interfaces.
  • D. The LAG interfaces are in a passive state.

Answer: A

Explanation:
In the exhibit, the ae0 and ae1 interfaces are in a link down state. This occurs when no physical interfaces (member interfaces) have been added to the LAG (Link Aggregation Group) interfaces, or the member interfaces are not operational.
Step-by-Step Breakdown:
LAG Configuration:
A LAG interface (aggregated Ethernet interface) is a logical interface that combines multiple physical interfaces for redundancy and increased bandwidth. The LAG will only be operational if at least one member interface is active and configured correctly.
No Operational Member Interfaces:
If no member interfaces are added or if the member interfaces are down, the LAG will remain in a down state, as shown in the exhibit for ae0 and ae1. Resolution:
Verify that physical interfaces have been added to the LAG using commands like:
LAG Interface Status: In Juniper, the link status of the LAG depends on its member interfaces, which must be operational for the LAG to function.
