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	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.
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	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) 認定 JN0-281 試験問題 (Q116-Q121):

質問 # 116
Which two prefixes are contributing routes to a 10.20.0.0/18 aggregate route? (Choose two)

• A. 10.20.0.0/16
• B. 10.20.0.0/24
• C. 10.20.100.0/24
• D. 10.20.60.0/23

正解：B、D

 

質問 # 117
What are three correct layer names used in legacy hierarchical network design? (Choose three.)

• A. Function layer
• B. Core layer
• C. Modular layer
• D. Aggregation layer
• E. Access layer

正解：B、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 # 118
Exhibit:

How many stages are shown in the exhibit?

• A. 0
• B. 1
• C. 2
• D. 3

正解：C

解説：
The exhibit shows a Folded IP Clos Architecture, which is also referred to as a 3-stage Clos network design. This architecture typically consists of two layers of switches:
Spine Layer: The top row of switches.
Leaf Layer: The bottom row of switches.
Step-by-Step Breakdown:
Clos Architecture:
A 3-stage Clos network has two types of devices: spine and leaf. In this design, each leaf switch connects to every spine switch, providing a high level of redundancy and load balancing.
Stage Explanation:
Stage 1: The first set of leaf switches.
Stage 2: The spine switches.
Stage 3: The second set of leaf switches.
The Folded Clos architecture shown here effectively "folds" the 3-stage design by combining the ingress and egress leaf layers into one, reducing it to two visible layers, but still maintaining the overall 3-stage architecture.
Juniper Reference:
IP Clos Architecture: The 3-stage Clos design is commonly used in modern data centers for high availability, redundancy, and scalability.

 

質問 # 119
Which static routing parameter will silently drop the packet if it is set as the next hop?

• A. Discard
• B. Resolve
• C. Reject
• D. Readvertise

正解：A

解説：
When the discard option is configured as the next hop for a static route, it silently drops any packets that match the route without sending any notification to the sender.
Step-by-Step Breakdown:
Discard Behavior:
If a route uses the discard next hop, the router drops the packet without generating any ICMP message or error back to the sender. This is useful for creating null routes to prevent routing loops or blackhole traffic intentionally.
Reject vs. Discard:
The reject next hop, in contrast, drops the packet but sends an ICMP Destination Unreachable message back to the source.
Juniper
Reference: Static Route Behavior: In Junos, the discard option ensures packets matching a static route are dropped silently, providing a way to discard traffic without alerting the source.

 

質問 # 120
Which route is preferred by the Junos OS software routing tables?

• A. Aggregate
• B. BGP
• C. Static
• D. Direct

正解：D

解説：
In Junos OS, direct routes are the most preferred routes in the routing table, having the highest priority.
Step-by-Step Breakdown:
Direct Routes:
Direct routes represent networks that are directly connected to the router's interfaces. Since these routes are directly accessible, they are assigned the highest priority and always take precedence over other types of routes.
Preference Values:
Direct routes have a preference of 0, which is the most preferred in Junos. Static routes, OSPF routes, and BGP routes have higher preference values and will only be used if there are no direct routes to the destination.
Juniper Reference:
Direct Route Preference: In Junos, direct routes are always preferred over other routes, ensuring that the router forwards traffic through locally connected networks.
