Exam 70-226
Designing Highly Available Web Solutions with Microsoft Windows 2000 Server Technologies
Exam 70-226 has been available since September 5, 2001.
This exam includes new types of questions that are very different from other exam formats currently in use. We strongly urge MCP candidates to take the following steps to help prepare for the exam. We recommend that you download and try Microsoft's Case Study-Based Test Demo to become familiar with these new types of questions before taking the exam. If you do not try the demo first, you may find that you are not adequately prepared for the exam's unique format. No tutorials are available at the Vue or Prometric testing centers.

Microsoft Certification Path
When you pass this exam, you achieve MCP (Microsoft Certified Professional) status. You also earn either core or elective credit toward your MCSE (Microsoft Certified Systems Engineer) certification.
Target Audience
Candidates for this exam may 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 of 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, secure 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 Web solutions that incorporate Microsoft Windows 2000 Server technologies. Before taking the exam, you should be proficient in the job skills listed below.
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.
