General Information
CCIE Service Provider Written Exam #350-023
The written exam is a two-hour, multiple choice test with 100 questions covering areas

such as Layer 2 networking, IP protocols, MPLS, VPN, security, quality of service and

high availability technologies. The exam is closed book and no outside reference

materials are allowed.

Beta Exams
Each written exam version is offered first in beta form at a discounted cost of US$50.

Beta exams are scheduled as you would other written exams and are available at all

worldwide testing locations. A passing grade on the beta qualifies a candidate to

schedule the lab exam. Results, however, are typically not available until six to eight

weeks after the close of the beta. A candidate may attempt the beta exam only once

during the beta period.

Cost
Written exams are administered by independent vendors at cost of US$300. Costs may vary

due to exchange rates and local taxes (VAT, GST).

Expiration
Candidates must make an initial attempt of the CCIE lab exam within 18 months of passing

the CCIE written exam. Valid passing scores on written exams expire after 18 months.

Locations
Written exams are taken at any worldwide VUE testing facility. See their websites for

more details.

Recertification
In addition to the comprehensive CCIE SP written exam #350-023, candidates may also take

one of the following exams for recertification purposes: SP Optical #350-020, SP Cable

#350-023, SP WAN Switching #350-023 or SP Content Networking #350-026. Half of the exam

covers general IP networking (50 questions) and the other half covers the specific

service delivery technology (50 questions). The blueprints for the exams are available

online as indicated in the links. As of February 1, 2007, these individual technology

exams no longer qualify a candidate for the CCIE SP lab exam.

Results
Written exam results are Pass/Fail and are available immediately following the exam. The

passing score is set by statistical analysis and is subject to periodic change.

Retakes
Candidates must wait five days between attempts at the written exam. Once a candidate

has passed the exam, he or she may not take the same exam again (for recertification

purposes) for at least 180 days.

The written exam is a two-hour, multiple choice test with 100 questions covering areas

such as Layer 2 networking, IP protocols, MPLS, VPN, security, quality of service and

high availability technologies. The exam is closed book and no outside reference

materials are allowed.

What configuration guarantees a level of Frame Relay service of 512K but reports a
guaranteed service of 1024K in LMI?
A. CIR=1024K, QIR=512K, MIR=512K, PIR=512K, percent utilization = 50%
B. CIR=512K, QIR=1024K, MIR=1024K, PIR=2048K, percent utilization = 50%
C. CIR=1024K, QIR=1024K, MIR=512K, PIR=2048K, percent utilization = 100%
D. CIR=512K, QIR=512K, MIR=1024K, PIR=512K, percent utilization = 100%
Answer: C
The IGX guarantees service based on MIR, so in order to guarantee 512K, you need MIR
x %util to = 512K
