  2. MAC address learning
  3. IGMP filtering
  4. IP address learning of interested VTEPs
Correct answer: BD
Question 4
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?
  1. QFX5110
  2. QFX10002
  3. EX4600
  4. EX4300
Correct answer: A
Question 5

Which Junos feature would you use to accomplish this task?
  1. graceful restart
  2. antispam
  3. AppSecure
  4. Virtual Chassis
Correct answer: C
Question 6
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?
  1. MC-LAG
  2. RTG
  3. LAG
  4. ESI
Correct answer: C
Question 7
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.) 
  
  1. You should use BA classifiers on R1.
  2. You should use multifield classifiers on R2, R3, and R4.
  3. You should use multifield classifiers on R1.
  4. You should use BA classifiers on R2, R3, and R4.
Correct answer: AB
Question 8
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.)  
  
  1. You must put the connections between the VMs and the vSRX device in separate VLANs.
  2. You must put the connections between the VMs and the vSRX device in separate vSwitches.
  3. You must put the connection between the VMs and the vSRX device in the same VLAN.
  4. You must put the connection between the VMs and the vSRX device in the same vSwitch.
Correct answer: AB
Question 9
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? 
  
  1. A physical link must be added between spine 2 and spine 3 and between spine 1 and spine 4.
  2. Additional physical links between spine 1 and spine 2 and between spine 3 and spine 4 must be added for resiliency.
  3. No physical links need to be added or removed.
  4. The physical links between spine 1 and spine 2 and between spine 3 and spine 4 must be removed.
Correct answer: D
Question 10
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?
  1. Integrated software is used to insert a software widget into the flow of network traffic.
