Juniper JN0-281 시험요강:

주제
소개

주제 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.

주제 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.

주제 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.

주제 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.

주제 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.

최신 JNCIA-DC JN0-281 무료샘플문제 (Q104-Q109):

질문 # 104
Which two statements are correct about BGP? (Choose two.)

A. IBGP peers do not advertise routes learned from IBGP peers to other IBGP peers.
B. EBGP sessions are typically established between router loopback interfaces.
C. EBGP uses the AS path to avoid loops.
D. IBGP sessions are typically established between physical router interfaces.

정답：A,C

질문 # 105
Which statement is correct about an IRB interface?

A. An IRB interface trunks together VLANs on different switches.
B. An IRB interface switches traffic within the same VLAN.
C. An IRB interface is a Layer 3 interface that can be used to route between VLANs.
D. An IRB interface is a physical Layer 3 interface that connects VLANs together.

정답：C

설명：
An IRB (Integrated Routing and Bridging) interface provides routing functionality between VLANs at Layer 3, allowing devices in different VLANs to communicate with each other.
Step-by-Step Breakdown:
IRB Functionality:
The IRB interface enables routing between different VLANs by acting as a Layer 3 gateway. Traffic within the same VLAN is handled by Layer 2 switching, while traffic between VLANs is routed through the IRB interface.
Layer 3 Routing Between VLANs:
Each VLAN can be assigned an IP address on the IRB interface, which allows traffic to flow between VLANs based on Layer 3 IP routing.
Juniper
Reference: IRB Interface Configuration: Juniper supports IRB for inter-VLAN routing on devices like the EX and QFX series switches, facilitating Layer 3 communication in data centers.

질문 # 106
When troubleshooting an OSPF neighborship, you notice that the router stopped at the ExStart state.
What is the cause of this result?

A. There is an area ID mismatch.
B. The priority is set to 255.
C. There is an MTU mismatch.
D. There is an interval timing mismatch.

정답：C

설명：
When an OSPF (Open Shortest Path First) neighborship is stuck in the ExStart state, it usually points to a mismatch in Maximum Transmission Unit (MTU) settings between two routers trying to establish the adjacency. The ExStart state is where OSPF routers negotiate the master-slave relationship and exchange DBD (Database Description) packets.
Step-by-Step Breakdown:
OSPF Neighbor States: OSPF goes through several states to establish an adjacency with a neighbor:
Down: No hello packets have been received.
Init: Hello packets are received, but bidirectional communication isn't confirmed.
2-Way: Bidirectional communication is established.
ExStart: The routers are negotiating who will be the master and who will be the slave, and begin to exchange DBD packets.
Exchange: The routers start exchanging the database information.
Loading: The routers process the Link-State Advertisements (LSAs).
Full: The adjacency is fully established.
MTU Mismatch Issue:
During the ExStart state, both OSPF routers must agree on their MTU values. If there is an MTU mismatch between the two routers, OSPF neighbors will fail to move from the ExStart to the Exchange state. The router with the larger MTU setting will not accept DBD packets from the router with a smaller MTU because the packets may exceed the smaller MTU size.
In Juniper devices, this behavior can be identified by examining the MTU settings using the show interfaces command and ensuring both routers have matching MTU configurations. To resolve this issue, either match the MTU settings on both routers or configure OSPF to ignore MTU mismatches using the command set protocols ospf ignore-mtu.
Juniper
Reference: Junos Command: show ospf neighbor helps diagnose neighbor states.
MTU Adjustment: set interfaces <interface-name> mtu <size> can be used to set the MTU values correctly.

질문 # 107
Which OSPF router type connects an OSPF area to non-OSPF networks?

A. Autonomous System Boundary Router (ASBR)
B. Backbone Router
C. Area Border Router (ABR)
D. Internal Router

정답：A

질문 # 108
Which two protocols can you use for a data center underlay network? (Choose two)

A. EBGP
B. VXLAN
C. EVPN
D. OSPF

정답：A,D
