Exam News
Exam 70-226 became available September 5, 2001.
Audience Profile
Candidates for this exam work in medium to very large
Internet or corporate intranet environments that use Microsoft
Windows 2000 operating systems. They have a minimum of two
years' experience planning and designing highly available Web
site infrastructures. They work in multiserver, n-tier
application environments that have the following
characteristics:
- Concurrent client connections that can exceed 1,000.
- Transactional applications.
- User databases, such as LDAP server or directory service.
- Internet security, such as firewalls, security-enhanced
protocols, or proxy servers.
- High availability services that can include Network Load
Balancing (NLB), Component Load Balancing (CLB), Cluster
service, and Microsoft Application Center 2000.
Skills Being Measured
This certification exam measures your ability to design and
implement database solutions by using Microsoft SQL Server 2000
Enterprise Edition. Before taking the exam, you should be
proficient in the job skills listed in the following matrix.
| Designing
Cluster and Server Architectures for Web Solutions |
| Design NLB solutions to
improve availability, scalability, and fault tolerance.
Considerations include the number of hosts, number of
clusters, placement of servers, multicast versus unicast,
failover strategy, priority, affinity, filtering, load
weighting, and application types. |
| Design Cluster service
cluster solutions to improve fault tolerance. Considerations
include the number of nodes, placement of servers, cluster
resource groups, failover and failback strategy,
active/active, active/passive, application types, and
dependencies. |
| Design CLB solutions to
provide redundancy and load balancing of COM+ components.
Considerations include the number of nodes, placement of
servers, NLB, and CLB routing. |
| Design data storage for
high availability. Considerations include RAID and storage
area networks. |
| Design a system management
and monitoring strategy. Considerations include performance
monitoring, event monitoring, services, data analysis, and
WMI. |
| Design a disaster recovery
strategy. |
| Designing a
Highly Available Network Infrastructure |
| Design a TCP/IP network
infrastructure. Considerations include subnet addressing,
DNS hierarchy and naming, DHCP server environment, and
routed and switched environments. |
| Design a highly available
network topology. Considerations include redundant paths,
redundant services, and redundant components. |
| Plan server configurations.
Considerations include network adapters, cluster
communication, connectivity, and bandwidth. |
| Analyze and design
end-to-end bandwidth requirements throughout an n-tier
environment. |
| Planning
Capacity Requirements |
| Calculate network, server,
and cluster capacity. Considerations include memory, CPU,
cost, flexibility, manageability, application scalability,
and client/server and server/server communications. |
| Design an upgrade strategy
for networks, servers, and clusters. Considerations include
scaling up and scaling out. |
| Calculate storage
requirements. Considerations include placement, RAID level,
and redundancy. |
| Design directory services.
Considerations include Active Directory™, LDAP,
availability, authentication, and sizing. |
| Designing
Security Strategies for Web Solutions |
| Design an authentication
strategy. Considerations include certificates, anonymous
access, directory services, Kerberos, and public key
infrastructure (PKI). |
| Design an authorization
strategy. Considerations include group membership, IP
blocking, access control lists, and Web content zones. |
| Design an encryption
strategy. Considerations include IPSec, SSL, certificates,
Encrypting File System (EFS), and PPTP. |
| Design a firewall strategy.
Considerations include packet filters, proxy servers,
protocol settings, network address translation (NAT), and
perimeter networks (also known as DMZs). |
| Design a security auditing
strategy. Considerations include intrusion detection,
security, performance, denial of service, logging, and data
risk assessments. |
| Designing
Application and Service Infrastructures for Web Solutions |
| Design a Microsoft Exchange
2000 Server messaging Web integration strategy.
Considerations include browser access and Wireless Access
Protocol (WAP) gateways. |
| Design a database Web
integration strategy. Considerations include database access
and authentication. |
| Design content and
application topology. Considerations include scaling out,
load balancing, fault tolerance, deploying and synchronizing
Web applications, state management, service placement, and
log shipping. |
| Design an n-tier,
component-based topology. Considerations include component
placement and CLB. |
| Design an application
management and monitoring strategy. Considerations include
detection and notification of application failure. |
