A data center requires an audit for ANSI/TIA-942 Rated-3 compliance. Will the network architecture be part of this audit?

• A.No, as concurrent maintainability only applies to electrical and mechanical
• B.No, only the type of cabling used will be audited
• C.Yes, but only if network administration does not comply with ANSI/TIA-606
• D.Yes, amongst other aspects the network architecture should be Rated-3 compliant with ANSI/TIA-942
