Question 1

Networking Fundamentals

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 proximity and, in some cases, reside on different floors. The interconnected racks will never exceed a distance of more than 300 meters (925 feet) from each other. The connections within the customers environment are 10GbE and 40GbE. The customers 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.)

A Use multimode fiber connections between all customer racks.
B Use single-mode fiber connections within a customer rack.
C Use DAC connections between all customer racks.
D Use DAC connections within a customer rack.

Which encapsulation is used on the cascade ports of a Junos Fusion aggregation device?

A PBB
B IEEE 802.1BR
C Broadcom HiGig2
D MPLS

A customer is using a Clos IP fabric design in their data center.
What is the advantage of using EBGP signaling between spine and leaf nodes rather than IBGP in this scenario?

A An EBGP router automatically performs the next hop self-operation on advertised routes.
B By default, EBGP supports multihop sessions between peers.
C A leaf node can have multiple EBGP sessions with a spine node.
D EBGP does not require support for the ADD-PATH capability.

You are about to deploy the Cloud Analytics Engine in your data center. However, some of the devices in your data center are not supported by the Cloud
Analytics Engine.
In this scenario, which two actions would occur? (Choose two.)

A The QFX Series devices report more than the IP address and hop number.
B The EX Series devices report more than the IP address and hop number.
C The non-Junos devices report more than the IP address and hop number.
D The MX Series devices only report the IP address and hop number.

Your customer has decided to implement a Layer 3 Clos IP fabric in their data center. They want to use IBGP and avoid using the full mesh requirement in this deployment scenario.
Which two actions would accomplish this task? (Choose two.)

A Use well-known communities on all advertised routes.
B Use BGP confederations.
C Use AS path prepend policies.
D Use route reflection within the design.

Configuration Basics

A customers data center is built with a QFX3000-G composed of four QFX3008-I Interconnects, four QFX5100-48S nodes in the network Node group, and 20
QFX5100-48S nodes spread in 10 redundant server Node groups. There are host systems (FCoE clients) scattered everywhere throughout the data center.
In this scenario, where should the FCoE-to-FC gateway(s) be placed?

A QFX3500s must be placed into the network Node group to provide a centralized FC-to-FCoE gateway.
B QFX3500s must be placed external to the QFX3000-G to provide an external FC-to-FCoE gateway.
C QFX3500s must be placed directly attached to the QFX3008-I Interconnects as a new Fibre Channel Node group to provide a centralized FC-to-FCoE gateway.
D Every Node which has FCoE client servers must become its own FC-to-FCoE gateway to provide a distributed FC-to-FCoE gateway.

The QFX5100 can be configured to be a virtual tunnel endpoint (VTEP) in your Clos IP fabric.
What is the importance of this capability?

A It allows the QFX5100 to perform the PE role of an EVPN.
B It allows attached bare metal servers to communicate using an overlay VXLAN network.
C It prevents the QFX5100 from learning the MAC addresses of an overlay network.
D It allows the QFX5100 to perform the PE role of a Layer 2 pseudowire.

A customer wants to implement redundancy in the core and at the edge with a single IP address for management in their data center. They have 200 servers dual- homed with two 10 Gbps fiber ports, and two 1 Gbps copper ports for management and testing. In addition, they have a redundant iSCSI array with two 40 Gbps ports each.
In this scenario, which solution meets the customers requirements?

A a QFabric system using QFX3000-M with two QFX3600-Is, two QFX3008 Directors, along with eight EX4300-48Ts, and nine QFX5100-48Ss as node devices.
B a Virtual Chassis Fabric solution consisting of two QFX-5100-24Q as spine nodes and the leaf nodes consisting of eight EX4300-48Ts and nine QFX5100- 48Ss operating in mix mode VCF
C a dual core switch design with two EX9208s in an MC-LAG architecture with nine dual-homed QFX5100-48Ss and eight dual-homed EX4300-48Ts
D a Virtual Chassis solution consisting of one Virtual Chassis with nine QFX5100-48Ss and one Virtual Chassis with eight EX4300-48Ts

Which three statements describe a one-armed firewall deployment in a data center? (Choose three.)

A It requires at least two interfaces for ingress and egress.
B It may be virtualized or hardware based.
C It may be deployed in high availability mode.
D It requires that all traffic flows directly through the firewall.
E It requires a routing policy to determine which traffic passes through the firewall.

You are implementing a new financial application in your data center. You must ensure Web traffic to this server is secure.
Which Junos feature would you use to accomplish this task?

A graceful restart
B antispam
C AppSecure
D Virtual Chassis

A customer wants to build a new data center based on the QFX3000-M. The data center must support 30 high traffic volume host servers. Each server will be dual connected to the fabric with two 40 Gbps links. The customer requires that there be a 1:1 subscription ratio within the fabric.
How should the QFX3000-M be configured to meet the customers requirements?

A Use four QFX5100-24Q Interconnect chassis to which each of 30 QFX35000 nodes will be dual connected with two 40 Gbps FTE links to each QFX5100-24Q.
B Use four QFX3600-I Interconnect chassis to which each of eight QFX3600 nodes will be dual connected with two 40 Gbps FTE links to each QFX3600-I.
C Use eight QFX3600-I Interconnect chassis to which each of 16 QFX3600 nodes will be connected with a 40 Gbps FTE link to each QFX3600-I.
D Use four QFX3008-I Interconnect chassis to which each of 16 QFX3600 nodes will be dual connected with two 40 Gbps FTE links to each QFX3600-I.
