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 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.
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	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 5	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.

Juniper Data Center, Associate (JNCIA-DC) Sample Questions (Q63-Q68):

NEW QUESTION # 63
You are troubleshooting a downed BGP session.

Referring to the exhibit, what is the cause of the problem?

A. The local peer has sent an Update message but not received one from the remote peer.
B. The local peer has sent an Open message but not received one from the remote peer.
C. The UDP session between the peers has not been established.
D. The TCP session between the peers has not been established.

Answer: D

Explanation:
The BGP session in the exhibit shows the state as Connect, which indicates that the TCP session between the BGP peers has not been fully established. Step-by-Step Breakdown:
BGP State "Connect":
The Connect state is the second stage in the BGP finite state machine (FSM). At this stage, BGP is trying to establish a TCP session with the peer, but the session has not yet been successfully established.
A successful TCP three-way handshake (SYN, SYN-ACK, ACK) is required before BGP can progress to the OpenSent state, where the peers exchange BGP Open messages.
Possible Causes:
A firewall blocking TCP port 179.
Incorrect IP addresses or network connectivity issues between the BGP peers. Juniper Reference: BGP Troubleshooting: In Junos, if a BGP session is stuck in the Connect state, the issue is likely due to a failure in establishing the underlying TCP connection.

NEW QUESTION # 64
What is the function of the 'Weight' attribute in BGP, and where is it used in the route selection process?

A. It is used to balance load among multiple links and is considered after the MED attribute.
B. It determines the stability of a route and is checked after the Local Preference attribute.
C. It is used to prioritize routes received from different EBGP peers and is considered before the AS_PATH attribute.
D. It is a Cisco-specific attribute used to prefer paths from one BGP speaker over another, evaluated before the Local Preference.

Answer: D

NEW QUESTION # 65
You are creating an IP fabric underlay and want to use OSPF as your routing protocol.
In this scenario, which statement is correct?

A. All spine devices must use the same router ID.
B. All leaf and spine devices must be the same model to ensure the proper load-balancing behavior.
C. All leaf devices must be configured in separate OSPF areas.
D. Interface speeds should be the same throughout the fabric to ensure that all links are utilized.

Answer: D

Explanation:
When creating an IP fabric underlay using OSPF as the routing protocol, consistent interface speeds are important to ensure optimal traffic distribution and utilization of all links.
Step-by-Step Breakdown:
OSPF and Interface Speeds:
OSPF calculates the cost of a link based on its bandwidth. The default cost calculation in OSPF is:

If interface speeds vary significantly, OSPF may choose paths with lower cost (higher bandwidth), resulting in some links being underutilized.
Equal Utilization:
To ensure that all links are equally utilized in an IP fabric, it is recommended to maintain uniform interface speeds across the fabric. This ensures balanced load sharing across all available paths.
Juniper Reference:
IP Fabric with OSPF: Juniper recommends consistent interface speeds to maintain even traffic distribution and optimal link utilization in IP fabric underlay designs.

NEW QUESTION # 66
Which state in the adjacency process do OSPF routers check the MTU size?

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

Answer: A

Explanation:
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.

NEW QUESTION # 67
Which OSPF packet types are used to establish and maintain neighbor relationships? (Choose two)

A. Hello packets
B. Database Description packets
C. Link State Request packets
D. Link State Update packets

Answer: A,B
