Certification Lev ls

Each JNTCP track has one to four rtification levels. Associate-level and

Specialist-level exams are comput r-based exams composed of multiple choice

questions. These computer-based exams are administered at Prometric testing

for

cente s wo ldwide and have no prerequisite certification requirements.

Professional-level and Expert-level exams are composed of hands-on lab exercises

that a e administered at select Juniper Networks testing centers. Professional-level

and Expe t-level exams require that you first obtain the next lower certification in the

track. Please visit the JNTCP Web site at

JUNOS Platform Cat gori s

The categories of Junip N tworks JUNOS platforms are as follows:

•

Multiservice routers (T Series, M Series, and J Series);

for

•

Ethe net services routers (MX Series);

•

Ethe net switches (EX Series);

•

Multi-access gateway (BX7000).

Juniper Netw rks T Series core routers provide the highest possible forwarding

per ormance density on the Internet today. They offer a wide selection of high-speed

and extremely high-speed interface options suited for service provider cores, while

maintaining feature richness and proven reliability.

Juniper Networks M Series Multiservice Edge Routers uniquely combine best-in-class

IP and MPLS capabilities with unmatched reliability, stability, security, and service

richness. These multiservice edge routers provide industry-leading port density across

a wide range of medium-speed to high-speed interface options and price points.

Juniper Networks J Series Services routers offer predictable high performance and a

variety of flexible interfaces that deliver secure, reliable network connectivity that is

cost effective for remote, branch, and regional offices, and for small businesses.

JUNOS Platforms Categories (contd.)

Juniper Networks MX Series Ethernet Services Routers provide Ethernet switching

capabilities without sacrificing carrier-class routing features customers expect.

MX Series devices have separate control and forwarding functions. Furthermore, the

router’s Ethernet switching separates Layer 2 and Layer 3 forwarding with the

intelligence to bridge when possible and route when needed.

Juniper Networks EX Series Ethernet Switches offer flexible, powerful, a d modular

platforms that deliver performance, scalability, and high availability. You can deploy

these products as a network access layer, as campus aggregation devices (within

high-density data centers), or as core switches.

Juniper Networks SRX Series Services Gateways are the next genera n security

services gateways based on the Dynamic Services Archi ec ure. The SRX Series

gateways enable secure deployment of a wide range of bus ness and residential

applications and services ranging from small to large en erprises, at service provider

premises and within data centers. The gateways offer native support for firewalls,

virtual private networks (VPNs), switching and carrierlass Ethernet routing, and

intrusion detection and prevention (IDP).

The Juniper Networks BX7000 Multi-Access Gateway operates within the

environmental constraints of the cell site an features such common uplink types as

copper, Ethernet, and DSL, to supp rt both legacy and next-generation mobile

technologies.

Performance and Reliability

All Juniper Networks JUNOS

latforms deliver deterministic forwarding performance

with servic s nabl

d. All

roducts employ the essential concept of separate

forwarding and control plan

s. By performing all complex, computation-intensive tasks

on an appropriat ly siz d control plane, these products ensure that tasks go

unhindered by any

gr

of forwarding requirements. Likewise, this separation

guarantees that the custom-designed forwarding plane always operates at peak

for

capacity, egardless of the complexity of control computations required at any given

moment.

JUNOS Software

T Series Core Rout rs

T Series Core Rout rs provide Gigabit Ethernet, SONET/SDH, and other high-speed

interfaces for large tworks and n twork applications, such as those that ISPs

support. Application-specific integrated circuits (ASICs) are a definitive part of the

for

router design. ASICs enable the router to achieve data forwarding rates that match

cu ent fiber-optic capacity. The T Series includes the T320, T640, T1600, and TX

M Series Multiservice Edge Routers

M Series Multiservice Edge Routers include the M7i, M10i, M40e, M120, and M320.
