Juniper JN0-281 Exam Syllabus Topics:

Topic
Details

Topic 1

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 2

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 3

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 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

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) Sample Questions (Q180-Q185):

NEW QUESTION # 180
Exhibit:

Referring to the exhibit, which two statements are correct about default BGP advertisements? (Choose two.)

A. When routes advertised by router2 are received by the SP router, they will contain the next-hop address of router1.
B. When routes advertised by the SP router are received by router2, they will contain the next-hop address of router1.
C. When routes advertised by router2 are received by the SP router, they will contain the next-hop address of router2.
D. When routes advertised by the SP router are received by router2, they will contain the next-hop address of the SP router.

Answer: A,B

Explanation:
The exhibit shows a BGP peering scenario between three routers: router1 and router2 are part of the same AS (AS65000), while the SP router is in a different AS (AS65101). This indicates an EBGP (External BGP) peering between the SP router and router1, and IBGP between router1 and router2.
Step-by-Step Breakdown:
Next-Hop Behavior in BGP:
IBGP: In IBGP, the next-hop address is not modified when advertising routes within the same AS. Thus, when router1 advertises routes learned from router2 to the SP router, it will keep the next-hop address of router1, not router2.
EBGP: In EBGP, the next-hop address is modified. When router1 receives routes from the SP router, it will advertise them to router2 with the next-hop address of router1.
Route Propagation:
Routes received by router1 from router2 will be advertised to the SP router with router1 as the next hop.
Similarly, routes advertised by the SP router will be passed on to router2, with router1 remaining as the next hop.
Juniper
Reference: BGP Next-Hop: Juniper's BGP implementations follow standard BGP next-hop behavior, where the next-hop is modified in EBGP but not in IBGP, ensuring proper route advertisement across autonomous systems.

NEW QUESTION # 181
What are the different OSPF area types? (Choose two)

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

Answer: A,C

NEW QUESTION # 182
Exhibit:

How many stages are shown in the exhibit?

A. 0
B. 1
C. 2
D. 3

Answer: D

Explanation:
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.

NEW QUESTION # 183
What is a VLAN?

A. A broadcast domain, identified by a VLAN ID
B. A local network using only virtual machines
C. A broadcast domain, using only virtual machines
D. A multicast domain, identified by a VLAN ID

Answer: A

NEW QUESTION # 184
A routing policy has been created to advertise OSPF routes in BGP. Which statement is correct in this scenario?

A. Apply the policy as an export policy within OSPF.
B. Apply the policy as an import policy within OSPF.
C. Apply the policy as an export policy within BGP.
D. Apply the policy as an import policy within BGP.

Answer: C

Explanation:
When advertising OSPF routes into BGP, the appropriate routing policy should be applied as an export policy in BGP.
Step-by-Step Breakdown:
OSPF to BGP Route Advertisement:
Routes learned via OSPF (a dynamic IGP) need to be exported into BGP to be advertised to external BGP peers. In Junos OS, this is done using export policies.
Export Policies in BGP:
An export policy controls which routes are advertised out of a BGP session. In this scenario, the routing policy must be applied to BGP as an export policy to export the OSPF-learned routes to external BGP peers.
Policy Configuration:
Example configuration:
set policy-options policy-statement EXPORT_OSPF term 1 from protocol ospf set policy-options policy-statement EXPORT_OSPF term 1 then accept set protocols bgp group <group-name> export EXPORT_OSPF This policy ensures that only OSPF routes are exported into BGP.
Juniper Reference:
Routing Policy: Export policies are used in BGP to control route advertisements to peers, including those learned via OSPF.
