SK0-003 · Question #73

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. To effectively recover servers after a power failure, prioritize bringing online foundational infrastructure services before dependent applications.

Question

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?

Options

  • ABring up the WINS server, the DNS server, then the web server
  • BBring up the web server, the time clock server, then the DHCP server.
  • CBring up the backup tape server, the DNS server, then the web server
  • DBring up the active directory server, the DNS server, then the web server

Why each option

To effectively recover servers after a power failure, prioritize bringing online foundational infrastructure services before dependent applications.

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

WINS is a legacy name resolution service and is not as critical for modern network operations as DNS or Active Directory.

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

A web server relies on foundational services like DNS and Active Directory, so it should not be brought up before them.

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

A backup tape server is important for data recovery but is not a foundational service required for other servers to initiate and operate in a network.

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

Active Directory provides authentication and authorization services, while DNS handles name resolution, both of which are critical prerequisites for most other network services and applications. Bringing these up first ensures that subsequent services like web servers can resolve hostnames and authenticate users properly to function.
