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 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 5
  • 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.

Juniper Data Center, Associate (JNCIA-DC) Sample Questions (Q131-Q136):

NEW QUESTION # 131
Which two statements are correct about rules for EBGP and IBGP? (Choose two.)

  • A. IBGP routes are more preferred than EBGP routes.
  • B. EBGP peers have a TTL of 255, while IBGP peers have a TTL of 1.
  • C. EBGP peers have a TTL of 1, while IBGP peers have a TTL of 255.
  • D. EBGP routes are more preferred than IBGP routes.

Answer: C,D

Explanation:
EBGP (External BGP) and IBGP (Internal BGP) operate with different rules due to the nature of their relationships.
Step-by-Step Breakdown:
TTL Differences:
EBGP: By default, EBGP peers have a TTL of 1, meaning they must be directly connected, or the TTL needs to be manually increased for multihop EBGP.
IBGP: IBGP peers within the same AS have a TTL of 255, as they are expected to communicate over multiple hops within the AS.
Preference for EBGP Routes:
Routes learned via EBGP are typically preferred over IBGP routes. This is because EBGP routes are considered more reliable since they originate outside the AS, while IBGP routes are internal. Juniper Reference: BGP Configuration: The different handling of TTL and route preferences between EBGP and IBGP ensures proper route selection and security within Junos-based networks.


NEW QUESTION # 132
Referring to the exhibit, how many broadcast domains are present in the topology?

  • A. 0
  • B. 1
  • C. 2
  • D. 3

Answer: D


NEW QUESTION # 133
Exhibit:

Referring to the exhibit, at which interval will the interface be considered down if no hello packets are received?

  • A. 400 seconds
  • B. 2000 milliseconds
  • C. 400 milliseconds
  • D. 2000 seconds

Answer: B

Explanation:
The exhibit shows the configuration of Bidirectional Forwarding Detection (BFD) for OSPF on interface xe-0/0/4.0, with the following parameters: minimum-interval: 400 milliseconds multiplier: 5 Step-by-Step Breakdown:
BFD Liveness Detection:
BFD is used to detect link failures at sub-second intervals, providing faster convergence times for routing protocols like OSPF. The minimum-interval is the time between BFD control packets (in milliseconds), and the multiplier indicates how many missed BFD packets trigger a failure.
Calculating Failure Detection Time:
The failure detection interval is calculated as:
Failure Interval=minimum-interval×multipliertext{Failure Interval} = text{minimum-interval} times text{multiplier}Failure Interval=minimum-interval×multiplier In this case:
400milliseconds×5=2000 milliseconds(2seconds)400 , text{milliseconds} times 5 = 2000 , text{milliseconds} (2 seconds)400milliseconds×5=2000milliseconds(2seconds) Conclusion:
If no BFD control packets are received within 2000 milliseconds (2 seconds), the interface will be considered down, triggering OSPF to recalculate routes. Juniper Reference: BFD Configuration: BFD parameters such as minimum-interval and multiplier are used to fine-tune the failure detection time for faster convergence.


NEW QUESTION # 134
Within your router, you want to verify that you are learning routes from a remote BGP peer at IP address 10.10.100.1.
Which command would satisfy the requirement?

  • A. show route receive-protocol bgp 10.10.100.1
  • B. show route protocol bgp table inet.0 10.10.100.1
  • C. show route protocol bgp source-gateway 10.10.100.1
  • D. show route advertise-protocol bgp 10.10.100.1

Answer: A

Explanation:
To verify that your router is learning routes from a remote BGP peer at a specific IP address (e.g., 10.10.100.1), the correct command to use is show route receive-protocol bgp.
Step-by-Step Breakdown:
BGP Route Learning:
The show route receive-protocol bgp command displays the routes that have been received from a specified BGP peer. This helps in confirming that the remote peer is sending routes correctly and that your router is receiving them.
Command Example:
show route receive-protocol bgp 10.10.100.1
This will show all routes that have been received from the BGP peer with IP address 10.10.100.1.Juniper Reference: BGP Route Verification: Use this command to troubleshoot and verify that routes from a specific BGP peer are being received.


NEW QUESTION # 135
What statement is true about load-balancing?

  • A. Load balancing on Juniper devices is processed per-packet.
  • B. Load balancing is only supported by dynamic routing protocols.
  • C. Load balancing on Juniper devices is processed per-flow.
  • D. Load balancing is only supported after applying an advanced license.

Answer: C
