Juniper JN0-281 認定試験の出題範囲：
トピック出題範囲
トピック 1
  • 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.
トピック 2
  • 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.
トピック 3
  • 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.
トピック 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.
トピック 5
  • 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.

Juniper Data Center, Associate (JNCIA-DC) 認定 JN0-281 試験問題 (Q102-Q107):質問 # 102
What are three correct layer names used in legacy hierarchical network design? (Choose three.)
  • A. Function layer
  • B. Modular layer
  • C. Aggregation layer
  • D. Core layer
  • E. Access layer
正解：C、D、E
解説：
In legacy hierarchical network design, three key layers are used to create a scalable and structured network:
Step-by-Step Breakdown:
Access Layer:
The access layer is where end devices, such as computers and IP phones, connect to the network. It typically involves switches that provide connectivity for devices at the edge of the network.
Aggregation Layer (Distribution Layer):
The aggregation layer (also called the distribution layer) aggregates traffic from multiple access layer devices and applies policies such as filtering and QoS. It also provides redundancy and load balancing.
Core Layer:
The core layer provides high-speed connectivity between aggregation layer devices and facilitates traffic within the data center or between different network segments.
Juniper Reference:
Legacy Hierarchical Design: Juniper networks often follow the traditional three-layer design (Access, Aggregation, and Core) to ensure scalability and high performance.

質問 # 103
What is the primary use of a virtual link in OSPF?
  • A. To connect an OSPF area to the backbone area through a non-backbone area.
  • B. To encrypt OSPF traffic.
  • C. To balance load across multiple links.
  • D. To connect OSPF areas to external networks.
正解：A

質問 # 104
When considering bidirectional forwarding detection, which two statements are correct? (Choose two.)
  • A. The BFD operation always consists of minimum intervals and multipliers.
  • B. The BFD default minimum interval is 3.
  • C. You can configure BFD per interface within the protocol stanza.
  • D. The BFD default multiplier is 5.
正解：A、C
解説：
Bidirectional Forwarding Detection (BFD) is a protocol used to detect faults in the forwarding path between two routers. It provides rapid failure detection, enhancing the performance of routing protocols like OSPF, BGP, and IS-IS.
Step-by-Step Breakdown:
Per Interface Configuration:
BFD can be configured on a per-interface basis within the protocol stanza (e.g., OSPF, BGP). This allows granular control over where BFD is enabled and the failure detection intervals for specific interfaces.
Minimum Interval and Multiplier:
BFD uses a minimum interval (the time between BFD control packets) and a multiplier (the number of missed packets before the path is declared down). The combination of these two defines the detection time for failures.
Juniper
Reference: BFD Configuration: In Juniper, BFD is configurable within routing protocol stanzas, with the failure detection mechanism always based on minimum intervals and multipliers.

質問 # 105
In a Virtual Chassis configuration, which of the following is true?
  • A. It allows physical stacking of switches that are geographically dispersed.
  • B. It reduces the operational complexity of managing multiple switches.
  • C. It decreases network redundancy and reliability.
  • D. Only two switches can be connected in a Virtual Chassis setup.
正解：B

質問 # 106
What are two requirements for an IP fabric? (Choose two.)
  • A. a Layer 2 switching protocol
  • B. a single connection between each leaf
  • C. a single connection between each spine and leaf
  • D. a Layer 3 routing protocol
正解：C、D
解説：
An IP fabric is a network architecture commonly used in data centers to provide scalable, high-throughput connectivity using a spine-leaf topology.
Step-by-Step Breakdown:
Layer 3 Routing Protocol:
An IP fabric relies on a Layer 3 routing protocol, typically BGP or OSPF, to provide routing between the leaf and spine switches. This ensures efficient traffic forwarding across the network.
Single Connection Between Spine and Leaf:
In an IP fabric, each leaf switch connects to every spine switch with a single connection. This ensures that traffic between any two leaf switches can travel through the spine layer in just two hops.
Juniper Reference:
Spine-Leaf Design: Juniper's IP fabric implementations are designed for scalability and low-latency routing, often using protocols like BGP for Layer 3 control.
