B. Data replication
C. Restoration automation
D. Revert to known state
D
A systems engineer decides that security mechanisms should differ for various systems in the organization. In some cases, systems will have multiple mechanisms. Which types of diversity does the engineer practice? (Select all that apply.)
A. Control
B. Vendor
C. Change
D. Resiliency
A,B
Management has reason to believe that someone internal to the organization is committing fraud. To confirm their suspicion, and to collect evidence, they need to set up a system to capture the events taking place. Evaluate which option will best fit the organization’s needs.
A. Honeynet
B. Honeypot
C. Exploitation framework
D. Metasploit
B
A hurricane has affected a company in Florida. What is the first step in the order of restoration?
A. Enable and test switch infrastructure
B. Enable and test power delivery systems
C. Enable and test network security appliances
D. Enable and test critical network servers
B
An organization stores data in different geographic locations for redundancy. This data replicates so that it is the same in all locations. Engineers discover that some replicas are lagging with updates. What configuration do the engineers discover as the cause?
A. Asynchronous replication
B. Synchronous replication
C. On-premises location
D. Cloud location
A
A systems engineer reviews recent backups for a production server. While doing so, the engineer discovers that archive bits on files are clearing and incorrect backup types have been occurring. Which backup type did the engineer intend to use if the bit should not be cleared?
A. Snapshot
B. Full
C. Differential
D. Incremental
C
A systems engineer configures a disk volume with a Redundant Array of Independent Disks (RAID) solution. Which solution does the engineer utilize when allowing for the failure of two disks?
A. Level 1
B. Level 0
C. Level 5
D. Level 6
D
Analyze automation strategies to differentiate between elasticity and scalability. Which scenarios demonstrate scalability? (Select all that apply.)
A. A company is hired to provide data processing for 10 additional clients and has a linear increase in costs for the support.
B. A company is hired to provide data processing for 10 additional clients and is able to utilize the same servers to complete the tasks without performance reduction.
C. A company has a 10% increase in clients and a 5% increase in costs.
D. A company has a 10% increase in clients and a 10% decrease in server performance.
A,C
An organization configures both a warm site and a hot site for disaster preparedness. Doing so poses which difficulties for the organization? (Select all that apply.)
A. Resiliency
B. Diversity
C. Complexity
D. Budgetary
C,D
Security specialists create a sinkhole to disrupt any adversarial attack attempts on a private network. Which solution do the specialists configure?
