Question1: You are re-designing a traditional multitiered data center into a modern spine-and-leaf data center architecture. In this scenario, which two tiers are collapsed? (Choose two.)

Question2: You are designing a Layer 2 fabric implementation for a small data center and have chosen to implement a Virtual Chassis Fabric. You must accommodate two racks of servers with 1 Gbps connectivity, 10 racks of servers with 10 Gbps connectivity, and maintain a single management interface.
Which device would satisfy the requirements in this implementation?

Question3: You need a security management solution for your data center that will support centralized network visibility and control, J-Flow collection from existing perimeter devices, and SIEM. In this scenario, which two products should you choose for your data center design? (Choose two.)

Question4: You are designing a data center network with a combination of KVM virtual machines and physical QFX Series devices. You require a single Juniper Networks solution for monitoring resource utilization across all devices. In this scenario, which product would satisfy this requirement?

Question5: You are designing a DCI strategy. You must provide a solution that meets the requirements shown below:
-sub 50 ms failover to alternate path
-supports L2 and L3 VPNs
-supports traffic engineered paths
Which technology would satisfy the requirements?

Question6: Which Junos NFV device is used to provide security in virtualized environments?

Question7: You are designing an IP fabric using IBGP as your underlay.
In this scenario, which statement is correct?

Question8: A customer asks you if they should implement nonstop active routing (NSR) in some cases to replace graceful restart in their data center.
In this scenario, which two statements are true? (Choose two.)

Question9: Which two statements about data center design are correct? (Choose two.)

Question10: Which devices are recommended by Juniper Networks as edge routers in a data center?

Question11: Which two statements are correct about current data center designs? (Choose two.)

Question12: Your company is deploying a private cloud based on OpenStack and has selected Contrail Networking as their SDN controller. Which statement is true in this scenario?

Question13: You are seeking a server-virtualization security solution that is lightweight and will protect virtual machines from a variety of threats.
Which platform should you choose in this scenario?

Question14: You have included in your data center design an SRX1500 chassis cluster. The RFP requires a documented upgrade process for the cluster that minimizes downtime. What satisfies this requirement in this scenario?

Question15: Click the Exhibit button. Referring to the exhibit, you want the vSRX device to inspect inter-VM traffic.
Which two actions must you take to accomplish this task? (Choose two.)

Question16: A customer is using EVPN to maximize their Data Center Interconnect and provide a stretched Layer 2 network to support VM mobility. What are two benefits in this scenario? (Choose two.)

Question17: Click the Exhibit button. Traffic congestion is noticed when sending traffic from S1 to S2. You must design a CoS deployment to address the traffic congestion issue. Referring to the exhibit, which two statements are true? (Choose two.)

Question18: Two data centers need to be connected for application and server mobility. An MPLS pseudowire is going to facilitate the necessary connectivity.
This pseudowire will extend between which two types of network devices?

Question19: Your data center uses a Virtual Chassis Fabric. The ToR switches have 48 ports and each rack supports
20 servers. Each server has two ports that are configured as a LAG.
You need to implement link level redundancy but you cannot use two ports on the same device for this redundancy.
Which type of connection should you use to complete this task?

Question20: Clos architectures are based on which network topology?

Question21: Which protocol is used on the VPCs of a Virtual Chassis Fabric?

Question22: How many inches does one RU equal?

Question23: You are implementing a new financial application in your data center. You must ensure Web traffic to this server is secure.
Which Junos feature would you use to accomplish this task?

Question24: Your SAN team must transmit FC between multiple locations in a data center. To keep the cost of the project to a minimum, your management decides that using FCoE would be the most cost-effective approach.
In this scenario, which architecture will support FCoE losslessly?

Question25: Which two security components are inherent in a Contrail vRouter? (Choose two.)

Question26: Which two statements are correct about a VCF deployment? (Choose two.)

Question27: Click the Exhibit button. You are designing a Layer 2 Ethernet fabric. Your customer wants to know which protocol in your design will ensure a loop-free topology. Referring to the exhibit, which protocol meets this requirement?

Question28: You are designing a Junos-based Ethernet Fabric for a data center that has a combination of 60 EX Series and QFX Series devices.
In this scenario, which solution would you choose?

Question29: What are two requirements for a VXLAN tunnel endpoint (VTEP)? (Choose two.)

Question30: A large multinational corporation wants to implement SDN for rapid deployment of application environments.
You are asked to define SDN service chaining for a presentation to execute management.
In this scenario, which statement would satisfy the requirement?

Question31: You are designing an IP fabric using EBGP.
In this scenario, what are two ways of designing the ASN scheme for the IP fabric? (Choose two.)

Question32: Click the Exhibit button. You are creating a resilient IP fabric for a data center based on a Clos architecture. Referring to the exhibit, which statement is true?

Question33: Which two statements describe the Contrail vRouter? (Choose two.)

Question34: You plan to deploy a set of SRX Series devices in an active/active chassis cluster with an active/active network infrastructure.
Which two statements are true in this scenario? (Choose two.)
