Demo Questions

Question 1
You are creating a design proposal and deciding whether to use 10 GbE copper or 10GbE fiber cabling to connect your ToR switches to the servers.  
Which statement is correct regarding this scenario?  
  1. Fiber has a lower power consumption on a per-port basis.
  2. Copper cabling requires special transceivers for different speeds.
  3. Fiber is much cheaper to purchase but has a higher long-term cost.
  4. Copper will allow you to reach the greatest distance between devices.
Correct answer: A
Question 2
What are two Layer 2 traffic tunneling schemes that are supported in a Juniper Networks IP fabric? (Choose two.)
  1. EVPN
  2. MPLSoGRE
  3. GENEVE
  4. VXLAN
Correct answer: AD
Explanation:
Question 3
Which two statements are true about IP fabrics? (Choose two.)
  1. IP-based applications do not require an overlay network to maintain connectivity.
  2. Applications that require security needs an overlay to provide the security.
  3. Applications that require Layer 2 adjacencies require an overlay network to maintain connectivity.
  4. IP fabrics can natively support both Layer 2 and Layer 3 applications.
Correct answer: CD
Question 4
Clos architectures are based on which network topology?
  1. ring
  2. VLANs
  3. hybrid
  4. spine and leaf
Correct answer: D
Question 5
What are two methods used to protect the data center perimeter? (Choose two.)
  1. session authentication
  2. DDoS protection
  3. asset classification
  4. network subnetting 
Correct answer: AB
Question 6
What are two requirements for a VXLAN tunnel endpoint (VTEP)? (Choose two.)
  1. TCP session tracking
  2. MAC address learning
  3. IGMP filtering
  4. IP address learning of interested VTEPs
Correct answer: BD
Question 7
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
Explanation:
Question 8
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 9
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 10
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
