The exhibit shows a data center that terminates all of the service chains into VRFs on the DC Gateway router. However, the DC Gateway router is reaching the limit of VRFs supported. Each service chain uses around 1.5 Gbps of bandwidth.

According to Juniper Networks, what should you recommend to overcome this problem?

  1. Deploy MX104s and terminate each service chain in a different VRF on each MX Series device.

  2. Deploy vMXs and terminate each service chain in a different VRF on each vMX.

  3. Deploy SRX240s and terminate each service chain in a different VRF on each SRX Series device.

  4. Deploy vSRXs and terminate each service chain in a different VRF on each vSRX.

Answer: D

Question No: 16

What are three advantages of VCF? (Choose three.)

  1. VCF leaf devices are directly connected to each spine device andofferlocal switching.

  2. VCF supports a mix of 1GbE, 10GbE, and 40GbE port speeds on the leaf devices.

  3. VCF supports PoE.

  4. VCF has a single point of administration.

  5. VCF supports FC SAN multihop.

Answer: A,B,D Explanation:

Virtual Chassis Fabric is a plug-and-play Ethernet fabric technology that allows you to combine a set of switches into a single logical switch. A Virtual Chassis Fabric has the following benefits:

  • Single point of management

  • Supports software-defined networking (SDN) with Virtual Extensible LAN (VXLAN) integration

  • Supports Fast Ethernet, Gigabit Ethernet,10-Gigabit Ethernet, and 40-Gigabit Ethernet interfaces

  • Full Layer 2, Layer 3, and multicast support

  • Equal-cost multipath (ECMP)

  • Scales up to 32 switches

You are designing a network for your company as shown in the exhibit. Applications residing on virtualized servers at each site need to be reachable at all times by the same IP address regardless of their location.

Which protocol must you include in the design to accomplish this task?

  1. MC-LAG

  2. IPsec

  3. EVPN

  4. VRRP

Answer: C

Question No: 20

Your customer is deploying a new data center in a collocation facility and will occupy several racks throughout the environment. The racks are not in close proximityand, in some cases, reside ondifferent floors. The interconnected racks will never exceed a distance of more than 300 meters (925 feet) from each other. The connections within the customer’s environment are 10GbE and 40GbE. Thecustomer’s requirements include high- performance operations, future proofing the connectivity design, and limiting the initial capital investment.

Which two recommendations would you provide the customer? (Choose two.)

  1. Use multimode fiber connections between all customer racks.

  2. Use single-mode fiber connections within a customer rack.

  3. Use DAC connections between all customer racks.
