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 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 (Q41-Q46):

NEW QUESTION # 41
Which two statements describe an IP fabric? (Choose two.)

  • A. An IP fabric depends on Layer 2 switching.
  • B. An IP fabric allows devices to always be one hop away.
  • C. An IP fabric provides traffic load sharing.
  • D. An IP fabric uses spine and leaf devices.

Answer: C,D

Explanation:
An IP fabric is a network topology designed to provide a scalable, low-latency architecture that is typically implemented in modern data centers. It uses spine and leaf switches and enables efficient traffic load sharing across the network.
Step-by-Step Breakdown:
Spine-Leaf Architecture:
Leaf Devices: These switches connect to servers and edge devices within the data center. Each leaf switch connects to every spine switch.
Spine Devices: These high-performance switches interconnect all the leaf switches. There are no direct connections between leaf switches or spine switches. This architecture ensures that any two endpoints within the fabric are only one hop away from each other, minimizing latency.
Traffic Load Sharing:
An IP fabric leverages Equal-Cost Multipath (ECMP) to distribute traffic evenly across all available paths between leaf and spine switches, providing effective load balancing. This ensures that no single link becomes a bottleneck and that traffic is distributed efficiently across the network. Juniper Reference: Juniper provides QFX Series switches optimized for IP fabric topologies, allowing for scalable deployments in modern data centers.
EVPN-VXLAN: Often used in IP fabrics to extend Layer 2 services across the fabric with Layer 3 underlay, enabling both efficient routing and bridging.


NEW QUESTION # 42
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 import policy within OSPF.
  • B. Apply the policy as an import policy within BGP.
  • C. Apply the policy as an export policy within BGP.
  • D. Apply the policy as an export policy within OSPF.

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.


NEW QUESTION # 43
What statement is true about load-balancing?

  • A. Load balancing is only supported by dynamic routing protocols.
  • B. Load balancing on Juniper devices is processed per-flow.
  • C. Load balancing is only supported after applying an advanced license.
  • D. Load balancing on Juniper devices is processed per-packet.

Answer: B


NEW QUESTION # 44
Layer 2 interfaces operate in which two modes? (Choose two.)

  • A. Trunk
  • B. Access
  • 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 # 45
What is the behavior of the default export policy for OSPF?

  • A. Accept all routes.
  • B. Forward all routes.
  • C. Reject all routes.
  • D. Redistribute all routes.

Answer: C

Explanation:
In Junos, the default export policy for OSPF is to reject all routes from being exported.
Step-by-Step Breakdown:
Default Export Policy:
By default, OSPF in Junos does not export any routes to other routing protocols or neighbors. This is a safety mechanism to prevent unintended route advertisements. Custom Export Policies:
If you need to export routes, you must create a custom export policy that explicitly defines which routes to advertise.
Example: You can create an export policy to redistribute static or connected routes into OSPF.
Juniper
Reference: OSPF Export Behavior: In Juniper devices, the default policy for OSPF is to reject route advertisements unless explicitly configured otherwise through custom policies.
