1. In an OSPF network with varying link speeds, you want to ensure the shortest path calculation accurately reflects interface bandwidths. Which parameter should you adjust globally to ensure that a 40GbE interface has a lower cost than a 10GbE interface?
A. The interface priority
B. The reference bandwidth
C. The hello interval
D. The dead interval
Answer: B
OSPF Metric Calculation and Reference Bandwidth: This knowledge point focuses on how OSPF determines the best path using interface cost. The cost is calculated based on a reference bandwidth divided by the interface bandwidth, making the reference bandwidth a critical global setting. In modern networks with high-speed links, adjusting this value ensures that faster interfaces are correctly preferred during shortest path calculation.

2. When configuring BGP, which attribute is used as the first tie-breaker in the Juniper Junos OS route selection process to prefer one path over another?
A. Local preference
B. AS path length
C. Origin type
D. Multi-exit discriminator
Answer: A
BGP Best Path Selection in Junos OS: This topic covers the BGP best path selection process specific to Juniper Junos OS. BGP evaluates multiple attributes in a defined order, with local preference being the first tie-breaker. Understanding this sequence allows network engineers to influence routing decisions and implement effective traffic engineering policies within an autonomous system.

3. In a BGP environment, what is the primary purpose of using the "Next Hop Self" policy on an Internal BGP peering session?
A. To reduce the size of the routing table
B. To ensure that external routes are reachable by internal peers
C. To prevent loops within the local autonomous system
D. To change the administrative distance of the route
Answer: B
Internal BGP Next-Hop Handling: This knowledge point addresses route reachability within an autonomous system. Internal BGP peers rely on correct next-hop information to forward traffic to external destinations. Policy-based next-hop handling ensures stable routing and avoids reachability issues in multi-router environments.

4. In a Layer 2 network, you want to prevent a single broadcast domain from becoming too large while still allowing multiple VLANs to share the same spanning tree instance to save CPU resources. Which spanning tree protocol should you implement?
A. Rapid Spanning Tree Protocol
B. Multiple Spanning Tree Protocol
C. VLAN Spanning Tree Protocol
D. Per-VLAN Spanning Tree Plus
Answer: B
Spanning Tree Optimization with Multiple VLANs: This topic focuses on improving Layer 2 scalability while maintaining loop prevention. By allowing multiple VLANs to share the same spanning tree instance, networks can reduce control-plane overhead and conserve switch resources. This approach is commonly applied in environments with a large number of VLANs.

5. Which technology is used in an EVPN-VXLAN fabric to encapsulate Layer 2 Ethernet frames into Layer 3 UDP packets for transport across an IP underlay?
A. Generic Routing Encapsulation
B. Virtual Extensible LAN
C. Label Distribution Protocol
D. Layer 2 Tunneling Protocol
Answer: B
EVPN-VXLAN Overlay Networking: This topic covers the use of overlay networking in modern data centers. VXLAN provides the data-plane encapsulation that transports Layer 2 frames across a Layer 3 network, while EVPN distributes reachability information through BGP. Together, they enable scalable and flexible network segmentation.
