Juniper JN0-281 Exam Syllabus Topics:

Topic	Details
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	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 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.
Topic 4	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 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 (Q149-Q154):

NEW QUESTION # 149
Which two statements about IBGP are correct? (Choose two.)

A. By default, IBGP has a TTL of 1.
B. IBGP uses AS path for loop prevention.
C. By default, IBGP has a TTL of 255.
D. IBGP uses full mesh for loop prevention.

Answer: C,D

Explanation:
IBGP (Internal Border Gateway Protocol) is used to exchange routing information between routers within the same AS (Autonomous System).
Step-by-Step Breakdown:
TTL of 255:
By default, IBGP sessions are established with a TTL (Time to Live) value of 255. This allows IBGP neighbors to communicate over multiple hops within the AS without requiring any additional configuration.
Full Mesh Requirement:
IBGP requires a logical full mesh between all IBGP routers to ensure that routing information is fully distributed within the AS. Since IBGP does not propagate routes learned from one IBGP peer to another by default, a full mesh topology is needed unless route reflectors or BGP confederations are used.
Juniper
Reference: IBGP Full Mesh: Juniper recommends using route reflectors in large networks to simplify IBGP full-mesh requirements.

NEW QUESTION # 150
In the context of data center networking, what is the primary purpose of an Underlay Network?

A. To handle external network connections exclusively.
B. To facilitate virtual machine migrations.
C. To provide a physical infrastructure for an Overlay Network.
D. To encrypt data traffic between servers.

Answer: C

NEW QUESTION # 151
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 advertise-protocol bgp 10.10.100.1
B. show route receive-protocol bgp 10.10.100.1
C. show route protocol bgp table inet.0 10.10.100.1
D. show route protocol bgp source-gateway 10.10.100.1

Answer: B

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 # 152
What are the different OSPF area types? (Choose two)

A. Not-So-Stubby Area (NSSA)
B. Virtual Link Area
C. Default-Free Zone
D. Stub Area

Answer: A,D

NEW QUESTION # 153
In troubleshooting a Virtual Chassis setup, what is a common issue to look for?

A. Activation of all ports for Virtual Chassis connections
B. Use of copper cables for inter-switch connections
C. Too many switches in a single Virtual Chassis configuration
D. Incompatible software versions between member switches

Answer: D
