Flashcards in 3.0 Network Operations Deck (34)
What defines proper system usage for employees when using information technology (IT) systems?
what type of policy would specify the rules and guidelines related to connecting a personally owned device to a corporate network?
what policy are employees typically required to read and acknowledge that outlines user responsibilities?
what UDP-based encryption protocol is often used for VPN access?
DTLS (datagram transport layer security)
what protocol uses SSH with FTP to securely transfer files?
why is telnet not recommended for use today?
lack of encryption
what should be used in place of telnet for better security?
what type of VPN allows users to access an internal network with a web browser?
note that SSL VPNs often use TLS
what protocol would you use to transfer large files?
what type of system would you use to consolidate and analyze security logs from multiple systems, in addition to providing real-time monitoring?
SIEM (security information and event management)
what option should you use to ensure SNMPv3 command and information remains confidential?
the authProv security level
what protocol would you use to securely manage network devices?
what should be done if a software update causes some features to no longer work?
Rollback the update
what process would an organization implement to ensure systems are kept up-to-date?
what is the best place to test updates to ensure they do not cause undesired outages?
Test server or test environment
what should a technician do if he is unable to complete a change within an approved maintenance window?
Rollback the change
what provides fault tolerance and can ensure systems to continue to operate after a disaster?
what is the term for combining multiple physical ports on a switch to a single virtual port?
assuming backups are performed daily, what type of backup plan minimizes the amount of time needed to restore backups?
Full with differential backups
a full backup every day would also minimize the amount of time needed to restore backups, but performing full backups daily is typically not feasible
assuming backups are performed daily, what type of backup plan minimizes the amount of time needed to perform backups?
Full with incremental backups
what continuity of operations site is the cheapest?
what continuity of operations site provides the shortest recovery time?
what provides an estimate of the amount of time it would take to restore a failed system?
MTTR (mean time to recover)
what provides a measure of a system's reliability and would provide an estimate of how often it is likely to experience an outage?
MTBF (mean time between failures)
what is provided with the use of two identical servers?
High availability and fault tolerance
what does an organization use to ensure a service provider meets minimum performance expectations?
what would you use to compare current network performance with past network performance to identify any changes?
where would you find the correct configuration settings for a server that was recently changed?
change management records
where would cables from external sources connect to within an organization?
MDF (main distribution frame)
