  Correct Answer: B

• Question 44:

  You have a heavily virtualized environment in which all of your virtual machines are hosted on a few large, shared servers. For security reasons, you must restrict inter-VM traffic and only allow traffic that complies with your security policies.

  A. URL filtering

  B. security intelligence

  C. vSRX

  D. VLAN

  Correct Answer: CD

• Question 45:

  Click the Exhibit button.

  

  Referring to the exhibit, what should you do to increase high availability?

  A. Deploy MC-LAG between the access layer and the servers.

  B. Deploy MC-LAG between the distribution layer and the access layer.

  C. Deploy a chassis cluster at the access layer.

  D. Deploy a Virtual Chassis at the distribution layer.

  Correct Answer: B

• Question 46:

  Click the Exhibit button.

  

  Which two statements about the redundancy design shown in the exhibit are true? (Choose two.)

  A. User traffic must be policy-routed to the active data center.

  B. Multicast IP addressing is in use.

  C. Inter-server traffic must use an alternate IP address.

  D. Anycast IP addressing is in use.

  Correct Answer: CD

• Question 47:

• Question 48:

  You are designing a new data center that will be built using an IP fabric. One of your security requirements is that the gateway for all of your VLANs must reside on the data center SRX firewalls.

  Which IP fabric architecture will satisfy this requirement?

  A. centrally routed overlay

  B. server routed overlay

  C. edge routed overlay

  D. bridged overlay

  Correct Answer: C

• Question 49:

  Which data center architecture is open, flexible, and uses Layer 3 only?

  A. STP

  B. IP fabric

  C. virtual chassis

  D. MC-LAG

  Correct Answer: B

• Question 50:

  You are designing a new Data Center Interconnect (DCI) that will be MPLS-based where the PE routers need to learn local and remote MAC addresses.

  In this scenario, which two DCI deployment methodologies satisfy this requirement? (Choose two.)

  A. VPLS

  B. LDP Layer 2 circuits

  C. EVPN

  D. BGP Layer 2 VPNs

  Correct Answer: BC
