Dual Power Supply and NIC Teaming | CompTIA Security+ Exam Answer

A network administrator needs to build out a new datacenter, with a focus on resiliency and uptime.

Which of the following would BEST meet this objective? (Choose two.)

A.

Dual power supply Most Voted

B.

Off-site backups

C.

Automatic OS upgrades

D.

NIC teaming Most Voted

E.

Scheduled penetration testing

F.

Network-attached storage.

AB.

The two options that would best meet the objective of building a new datacenter with a focus on resiliency and uptime are A) dual power supply and D) NIC teaming.

A) Dual power supply: This option involves having two power supplies connected to each server or networking device. If one power supply fails, the other can take over, providing redundancy and minimizing downtime. Dual power supply is a critical feature for datacenters since any interruption in power can cause system failures and data loss.

D) NIC teaming: This option involves combining multiple network interface cards (NICs) into a single logical interface to provide redundancy and load balancing. If one NIC fails, the traffic can be automatically redirected to the other NIC(s), preventing downtime. NIC teaming also helps distribute the network traffic evenly across multiple NICs, which can improve performance and reduce congestion.

B) Off-site backups: Although off-site backups are essential for disaster recovery and data protection, they are not directly related to resiliency and uptime. Off-site backups help restore data in case of a disaster, but they do not prevent system failures or reduce downtime.

C) Automatic OS upgrades: While automatic OS upgrades can improve system security and stability, they can also introduce new bugs and compatibility issues. Therefore, automatic OS upgrades should be carefully planned and tested before deployment. However, automatic OS upgrades are not directly related to resiliency and uptime.

E) Scheduled penetration testing: Penetration testing is an essential part of cybersecurity, but it does not directly improve resiliency and uptime. Penetration testing helps identify vulnerabilities and weaknesses in the system, but it does not prevent hardware failures or network outages.

F) Network-attached storage: Network-attached storage (NAS) is a storage device connected to the network that provides file-level access to multiple clients. Although NAS can provide data redundancy and scalability, it is not directly related to resiliency and uptime. NAS can help improve data availability, but it does not prevent system failures or reduce downtime.
