SK0-003 · Question #862

An administrator is attempting to recover from a power failure in the data center. Which of the following is the BEST way to recover the servers?

The correct answer is D. Bring up the active directory server, the DNS server, then the web server. The best recovery sequence after a power failure prioritizes essential infrastructure services. Bringing up Active Directory and DNS first ensures that name resolution and authentication services are available for subsequent servers.

Why each option

The best recovery sequence after a power failure prioritizes essential infrastructure services. Bringing up Active Directory and DNS first ensures that name resolution and authentication services are available for subsequent servers.

ABring up the WINS server, the DNS server, then the web server

WINS (Windows Internet Name Service) is a legacy service for NetBIOS name resolution and is not as critical as Active Directory and DNS for modern network operations.

BBring up the web server, the time clock server, then the DHCP server

Bringing up a web server or time clock server before foundational services like Active Directory and DNS would likely result in failures due to unavailable dependencies.

CBring up the backup tape server, the DNS server, then the web server

A backup tape server is used for data recovery, not for the initial bring-up sequence of essential network services after a power outage.

DBring up the active directory server, the DNS server, then the web serverCorrect

Bringing up the Active Directory server first ensures authentication and directory services are available, followed by the DNS server for name resolution, which are critical foundational services for most other servers like web servers to function correctly in an enterprise environment. Many applications and services depend on Active Directory for user and computer authentication, and DNS for resolving hostnames to IP addresses.
