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

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 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.

トピック 3

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 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 (Q114-Q119):

質問 # 114
In the context of protocol-independent routing, what is the main difference between static and generated routes?

A. Generated routes support summarization, while static routes do not.
B. Static routes are used for load balancing, while generated routes are not.
C. Static routes require manual configuration, while generated routes are created dynamically.
D. Generated routes are manually configured, while static routes are automatically created.

正解：C

質問 # 115
Which two statements are true with regards to MACsec?

A. It provides authentication for an Ethernet traffic between two network nodes.
B. It provides encryption for an Ethernet traffic between two network nodes.
C. It does not provide authentication for an Ethernet traffic between two network nodes.
D. It does not provide encryption for an Ethernet traffic between two network nodes.

正解：A、B

質問 # 116
Which three technologies improve high availability and convergence in a data center network? (Choose three.)

A. link loss adjacency
B. Bidirectional Forwarding Detection (BFD)
C. link aggregation group (LAG)
D. graceful restart (GR)
E. Failover Group (FG)

正解：B、C、D

解説：
High availability and fast convergence are critical in data center networks to minimize downtime and maintain optimal performance. The following technologies contribute to achieving these goals: Graceful Restart (GR):
GR allows routers to maintain forwarding state during control plane restarts, ensuring continuous packet forwarding while minimizing network disruptions. Bidirectional Forwarding Detection (BFD):
BFD provides fast detection of path failures, allowing routing protocols to converge quickly by detecting link failures much faster than traditional timers. Link Aggregation Group (LAG):
LAG increases both redundancy and bandwidth by combining multiple physical links into one logical link, providing load balancing and fault tolerance.
Juniper
Reference: High Availability Techniques: These technologies are fundamental in ensuring rapid recovery and failover within Juniper-based data center environments.

質問 # 117
What is the primary use of a virtual link in OSPF?

A. To encrypt OSPF traffic.
B. To connect OSPF areas to external networks.
C. To balance load across multiple links.
D. To connect an OSPF area to the backbone area through a non-backbone area.

正解：D

質問 # 118
Which state in the adjacency process do OSPF routers check the MTU size?

A. Init
B. Done
C. ExStart
D. Exchange

正解：D

解説：
In OSPF, routers exchange link-state information in different stages to establish full adjacency. The MTU size is checked during the Exchange state.
Step-by-Step Breakdown:
OSPF Adjacency Process:
OSPF routers go through multiple stages when forming an adjacency: Down, Init, 2-Way, ExStart, Exchange, Loading, and Full.
Exchange State:
During the Exchange state, OSPF routers exchange Database Description (DBD) packets to describe their link-state databases. The MTU size is checked at this stage to ensure both routers can successfully exchange these packets without fragmentation.
If there is an MTU mismatch, the routers may fail to proceed past the Exchange state.
Juniper Reference:
MTU Checking in OSPF: Junos uses the Exchange state to check for MTU mismatches, ensuring that routers can properly exchange database information without packet fragmentation issues.
