TEST 2 Flashcards
- A system engineer enhances the security of a network by adding firewalls to both the external network and the internal company network. The firewalls are products of two separate companies. This is an example of what type of security control practice?
A. Vendor diversity
B. Control diversity
C. Active-Passive
D. Single layer
A. Vendor diversity
- A startup company adds a firewall, an IDS, and a HIPS to its infrastructure. At the end of the week, they will install HVAC in the server room. The company has scheduled penetration testing every month. Which type of layered security does this represent?
A. Vendor diversity
B. TPM
C. Control diversity
D. HSM
C. Control diversity
- When workload heavily increased, a company-maintained service performance by manually installing an additional load balanced server. What feature of the IT architecture allowed this to occur?
A. Fault tolerance
B. Scalability
C. Availability
D. Elasticity
B. Scalability
- An aviation tracking system maintains flight records for equipment and personnel. The system is a critical command and control system that must maintain a global availability rate of 99%. The entire system is on a cloud platform that guarantees a failover to multiple zones within a region. In addition to the multi-zonal cloud failover, what other solution would provide the best option to restoring data and rebuilding systems if the primary cloud service becomes unavailable?
A. Offsite backup and storage
B. Online backup system
C. Offline backup system
D. Shadow copy
A. Offsite backup and storage
- A network administrator is installing a device that uses Redundant Array of Independent Disks (RAID) technologies for redundancy and provides employees remote access so that files can be accessed anywhere. The device does not require licensing and stores data at the file level. Which device is the employee likely installing in the infrastructure?
A. NAS
B. VDI
C. SAN
D. RDP
A. NAS
- A system engineer is researching backup solutions that are inexpensive and can store large amounts of data offline. The backup solution must be portable and maintainable for a certain length of time defined in the company’s backup recovery plan. Which of the following is the best backup solution?
A. NAS
B. Tape
C. Disk
D. SAN
B. Tape
- A system engineer has tested a new application in the lab and wants to deploy the application on a production server. The server is a virtual machine that processes and stores live data for company employees. Which of the following is the BEST approach for deploying the new application on the server?
A. Take a backup of the server after installing the application.
B. Test the new application in the sandbox before deploying.
C. Run vulnerability scans on the application.
D. Take a snapshot of the server before installing on the server.
D. Take a snapshot of the server before installing on the server.
- A company has implemented a Virtual Desktop Infrastructure (VDI) where the user’s desktop operates as a Virtual Machine (VM) on a centralized server. When users log off the machine, any changes made at the VM level are not saved. Which means of non-persistence has been implemented?
A. Revert to known state
B. Containerization
C. Live boot media
D. TPM
A. Revert to known state
- A company requires a means of managing storage centrally and the ability to share the storage with multiple hosts where users can access data quickly, with little to no latency. They need to use Fiber Channel to connect the storage media. Which of the following storage architectures would best meet the company’s needs?
A. NAS
B. Disk
C. RAID
D. SAN
D. SAN
Explanation: A Storage Area Network (SAN) is a network of storage devices that can be accessed by multiple servers or computers, providing a shared pool of storage space.
- A system engineer can monitor and control voltage factors in a data center. The engineer can make critical decisions on the center’s energy consumption and load balancing. Which device is the engineer likely using to make these decisions?
A. UPS
B. Generator
C. SIEM
D. Managed PDUs
Managed PDUs
- A data center needs to ensure that data is not lost at the system level in the event of a blackout. Servers must stay operable for at least an eight-hour window as part of the response and recovery controls implemented. Which redundancy effort should be put in place to ensure the data remains available?
A. Vault
B. Faraday Cage
C. UPS
D. PDU
C. UPS
- An application requires continuity of operations to be maintained. If there is an outage, it needs to be restored within a 24-hour period due to the command-and-control capabilities it maintains. The failover site must be physically separated from the program office and be available within the required timeframe with live data. Which of the following solutions best describes the physical implementation?
A. A. Failover clusters
B. B. Meantime between failure
C. C. Geographical dispersal
D. D. Recovery time objective
Geographical dispersal
