Exam 2: Data Center Design, Specialist (JNCDS-DC)

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?

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?

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?

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.)

You want to provide Layer 2 connectivity to a backup data center or to a disaster recovery site. What would you use to accomplish this task?

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?

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.)

Your data center uses an Ethernet fabric solution for the infrastructure switches. You must design a redundancy solution that addresses how the servers connect to the members of the Ethernet fabric. Which two statements are true in this scenario? (Choose two.)

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

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?

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?

You are asked to create a new data center based on an IP fabric architecture. The data center must support many segmented applications that require Layer 2 adjacencies. You decide to use EVPN-VXLAN as an overlay technology to accomplish the task. To meet the requirements, each application will be placed in its own VLAN. In this scenario, what is required for communication between VLANs to occur?

How many inches does one RU equal?

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?

Click the Exhibit button. Traffic congestion has been noticed when S1 is sending traffic to S2. You must design a CoS deployment to address the traffic congestion issue. Referring to the exhibit, which statement is true?

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

You want to use the Intrusion Prevention System features of a vSRX virtual firewall to protect systems from attacks embedded in traffic. In this scenario, which three technologies would be used? (Choose three.)

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?

What are two methods used to protect the data center perimeter? (Choose two.)

You are implementing a Virtual Chassis Fabric using QFX5110 devices. Which two statements are true in this scenario according to Juniper Networks recommendations? (Choose two.)
