1

What defines proper system usage for employees when using information technology (IT) systems?

AUP

2

what type of policy would specify the rules and guidelines related to connecting a personally owned device to a corporate network?

BYOD policy

3

what policy are employees typically required to read and acknowledge that outlines user responsibilities?

AUP

4

what UDP-based encryption protocol is often used for VPN access?

DTLS (datagram transport layer security)

5

what protocol uses SSH with FTP to securely transfer files?

SFTP

6

why is telnet not recommended for use today?

lack of encryption

7

what should be used in place of telnet for better security?

SSH

8

what type of VPN allows users to access an internal network with a web browser?

SSL VPN

note that SSL VPNs often use TLS

9

what protocol would you use to transfer large files?

FTP

10

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)

11

what option should you use to ensure SNMPv3 command and information remains confidential?

the authProv security level

12

what protocol would you use to securely manage network devices?

SNMPv3

13

what should be done if a software update causes some features to no longer work?

Rollback the update

14

what process would an organization implement to ensure systems are kept up-to-date?

patch management

15

what is the best place to test updates to ensure they do not cause undesired outages?

Test server or test environment

16

what should a technician do if he is unable to complete a change within an approved maintenance window?

Rollback the change

17

what provides fault tolerance and can ensure systems to continue to operate after a disaster?

Redundancy

18

what is the term for combining multiple physical ports on a switch to a single virtual port?

port aggregation

19

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

20

assuming backups are performed daily, what type of backup plan minimizes the amount of time needed to perform backups?

Full with incremental backups

21

what continuity of operations site is the cheapest?

Cold site

22

what continuity of operations site provides the shortest recovery time?

Hot site

23

what provides an estimate of the amount of time it would take to restore a failed system?

MTTR (mean time to recover)

24

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)

25

what is provided with the use of two identical servers?

High availability and fault tolerance

26

what does an organization use to ensure a service provider meets minimum performance expectations?

SLA

27

what would you use to compare current network performance with past network performance to identify any changes?

Baseline

28

where would you find the correct configuration settings for a server that was recently changed?

change management records

29

where would cables from external sources connect to within an organization?

MDF (main distribution frame)

30

what type of diagram would you use to identify the number of broadcast domains on a network?

logical network diagram
