CCA Citrix MetaFrame XP for Windows Administrator Study Guide (Exam 70-220)

Analyzing Load with Load Manager

• The load management feature only comes with MetaFrame XPa or XPe.

• MetaFrame installs with two evaluators: default and advanced.

• The default evaluator is assigned to all servers during their installation.

• The default evaluator monitors Server User Load and sets its threshold at 100 users.

• The advanced evaluator monitors Processor Utilization, Memory Utilization, and Page Swap.

• The default and advanced evaluators cannot be edited.

• Load balancing occurs at login. It is not dynamic.

• By default, no evaluator is assigned to published applications.

Identifying Encryption Strengths and Performance

• Public key-private key encryption uses one key to encrypt data and another to decrypt data.

• Symmetric key encryption uses the same key to encrypt and decrypt data.

• MetaFrame supports 40-, 56-, and 128-bit encryption.

• RSA's RC5 algorithm is a symmetric key algorithm, used to secure the ICA data stream.

• Diffie-Hellman is a public key-private key algorithm used to negotiate the symmetric key for ICA data encryption.

• Minimum encryption levels can be set at the connection level using Citrix Connection Configuration or per published application using the Citrix Management Console.

• DOS, Win16, Win32, Linux x86, and the Web clients support encryption.

• HTTPS is used to secure user credentials between the client and the Web server, while SSL Relay is used to secure the XML data connection between the Web server and the MetaFrame Server.
