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 3
  • 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 4
  • 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 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.

  • B. Load balancing is only supported by dynamic routing protocols.
  • C. Load balancing on Juniper devices is processed per-packet.
  • D. Load balancing on Juniper devices is processed per-flow.

Answer: D


NEW QUESTION # 174
Which of the following statements are true regarding Graceful Restart (GR)? (Choose two)

  • A. It decreases network stability during protocol restarts.
  • B. It is used to increase the convergence time of the network.
  • C. It requires support from both the restarting router and its neighbors.
  • D. It helps in maintaining uninterrupted forwarding during a routing process restart.

Answer: C,D


NEW QUESTION # 175
How can OSPF be configured to prefer one route over another?

  • A. By adjusting interface bandwidth.
  • B. By configuring route redistribution.
  • C. By setting a higher cost on the preferred route.
  • D. By setting a lower cost on the preferred route.

Answer: D


NEW QUESTION # 176
What is the primary function of a VLAN?

  • A. To provide a routing mechanism between different networks.
  • B. To segment a network into multiple broadcast domains.
  • C. To encrypt network traffic.
  • D. To control network traffic based on MAC addresses.

Answer: B


NEW QUESTION # 177
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.
  • 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, except for the ingress interface.

Answer: D

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.
