  Which routing protocol will satisfy this requirement?

  A. MPLS

  B. BGP

  C. IS-IS

  D. OSPF

  Correct Answer: B

  C. Control plane MAC learning is used.

  D. Data plane MAC learning is used.

  Correct Answer: C

• Question 24:

  You are deploying a new data center fabric to support virtualized systems. As part of the deployment, you

  must monitor server utilization of the hosts.

  Correct Answer: C

• Question 25:

  Your data center design must ensure that no access switch can become a single point of failure. Which two actions will satisfy this requirement? (Choose two.)

  A. Use an MC-LAG between two upstream distribution switches and each access switch.

  B. Use a LAG between each access switch and a VRRP interface on a distribution switch.

  C. Use a LAG between each server and two or more members of a Virtual Chassis.

  D. Use an MC-LAG between two access switches and each server.

  Correct Answer: AD

• Question 26:

  You want to encapsulate Layer 2 frames for transport across a Layer 3 network.

  Which three methods are supported by Juniper Networks to accomplish this task? (Choose three.)

  A. EVPN

  B. VXLAN

  C. MPLS over GRE

  D. Layer 3 VPN

  E. MPLS over UDP

  Correct Answer: ABC

• Question 27:

  What are two elements of data center security? (Choose two.)

  A. segmentation with VLANs in hypervisors

  B. DDoS protection

  C. ATP Cloud advanced anti-malware

  D. JIMS for user identify and management

  Correct Answer: AB

• Question 28:

  You are asked by the data center architecture team to evaluate redundancy and management options for server racks that have two or more switches to reduce the management footprint while maintaining redundancy.

  Which technology fulfills both requirements?

  A. Virtual Chassis

  B. ESI

  C. Virtual Router Redundancy Protocol

  D. MC-LAG

  Correct Answer: A

• Question 29:

  

  You are designing a data center where all your servers in each rack will be connected to two top-of-rack (ToR) switches using Layer 2, as shown in the exhibit. You must implement a high availability solution that maintains link layer connectivity to each server when one of the ToR switches fails.

  In this scenario, which solution will accomplish this task?

  A. Virtual Chassis with LAG

  B. chassis cluster with LAG

  C. non-stop bridging (NSB)

  D. bidirectional forwarding detection (BFD)

  Correct Answer: A

• Question 30:

  Which switch deployment solution will minimize server-to-switch cable lengths?

  A. top-of-rack

  B. middle-of-row

  C. middle-of-rack

  D. end-of-row

  Correct Answer: A
