QuestionQ327

Security

A network administrator needs to perform a system upgrade on a Cisco MDS 9000 Series Switch. Because of recent security-team changes:

  • The AAA server cannot be reached.
  • All TCP communication between the MDS 9000 Series Switch and AAA servers is disabled.

Which actions must be used to carry out the upgrade?

  • A Log in locally to the MDS 9000 Series Switch using a network-admin role and download the upgrade files from the remote TFTP server.
  • B Log in locally to the MDS 9000 Series Switch using a server-admin role and download the upgrade files from the remote FTP server.
  • C Log in to a server storing the upgrade files remotely using a server-admin role and download the files to the MDS 9000 Series Switch using SFTP.
  • D Log in to a server storing the upgrade files remotely using a network-admin role and download the files to the MDS 9000 Series Switch using HTTP.
Explanation

Local switch access is required when the AAA server is unreachable. The network-admin role can execute all commands and make configuration changes, which are necessary for an upgrade. TFTP is the supported non-TCP transfer method for copying MDS NX-OS images to bootflash, whereas FTP, SFTP, and HTTP depend on TCP.
