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

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 4

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 5

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.

Juniper Data Center, Associate (JNCIA-DC) Sample Questions (Q141-Q146):

NEW QUESTION # 141
A switch receives a frame with a MAC address of FF-FF-FF-FF-FF-FF. Which action will the switch take on this frame?

A. It will flood it out of all interfaces, except for the ingress interface.
B. It will flood it out of all interfaces, except for the directly connected VLAN.
C. It will flood it out of all interfaces, except for the next-hop interface.
D. It will flood it out of all interfaces.

Answer: A

Explanation:
A MAC address of FF-FF-FF-FF-FF-FF is the Ethernet broadcast address. When a switch receives a frame with this destination MAC address, it is required to forward the frame to all interfaces except the one it was received on.
Step-by-Step Breakdown:
Broadcast Frame Handling:
When a frame with the broadcast MAC address is received, the switch will flood it out of all active ports that belong to the same VLAN as the incoming frame. The broadcast frame is not sent back out of the ingress interface (the interface where the frame was originally received).
Purpose of Flooding:
Broadcasting is used to ensure that the frame reaches all devices within the broadcast domain (all devices within the same VLAN), which may not have a specific entry for the MAC address in their MAC address table.
Juniper Reference:
Layer 2 Frame Forwarding: Juniper switches flood broadcast frames to all ports in the same VLAN, except the port the frame was received on.

NEW QUESTION # 142
Layer 2 interfaces operate in which two modes? (Choose two.)

A. Access
B. Trunk
C. Modular
D. Tagged

Answer: A,B

Explanation:
Comprehensive Detailed Step by Step Explanation with all Juniper Data Center References Layer 2 interfaces on a switch operate in two key modes: Access and Trunk.
Step-by-Step Breakdown:
Access Mode:
Access ports are used to connect end devices, like PCs or servers, and they are assigned to a single VLAN. These interfaces handle untagged traffic and do not pass VLAN tags. Example: A port assigned to VLAN 10 will only handle traffic for that VLAN.
Trunk Mode:
Trunk ports are used to connect switches or other networking devices that need to handle traffic from multiple VLANs. Trunk interfaces carry tagged traffic, allowing multiple VLANs to traverse the same physical link.
Trunk ports typically use 802.1Q VLAN tagging to differentiate between VLANs.
Juniper
Reference: Access and Trunk Ports: Juniper switches use these modes to manage VLAN traffic at Layer 2, with access ports handling untagged traffic and trunk ports handling tagged traffic from multiple VLANs.

NEW QUESTION # 143
In Junos, which command is used to display the status of all interfaces?

A. show vlan brief
B. show interfaces terse
C. show interfaces descriptions
D. show ethernet-switching table

Answer: B

NEW QUESTION # 144
Which VLAN tagging method inserts a 4-byte tag into the Ethernet frame?

A. MPLS
B. Q-in-Q
C. Dot1Q
D. ISL

Answer: C

NEW QUESTION # 145
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 receive-protocol bgp 10.10.100.1
B. show route protocol bgp table inet.0 10.10.100.1
C. show route advertise-protocol bgp 10.10.100.1
D. show route protocol bgp source-gateway 10.10.100.1

Answer: A

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.
