A false positive alert is a type of IDS alert that occurs when the IDS mistakenly identifies benign or normal traffic as malicious or suspicious, and triggers an alarm, although there is no active attack in progress. A false positive alert can be caused by various factors, such as misconfigured IDS rules, outdated signatures, network anomalies, or legitimate traffic that resembles attack patterns. A false positive alert can waste the time and resources of the security team, as they have to investigate and verify the alert, and also reduce the trust and confidence in the IDS. A false positive alert can be reduced by tuning and updating the IDS, filtering out irrelevant traffic, and using multiple detection methods. A false positive alert is the type of IDS alert Jay has received in the above scenario, as he received an event triggered as an alarm, although there is no active attack in progress. Reference:

Correct : B

A coaxial cable is a type of network cable that is made up of a single copper conductor at its center and a plastic layer that provides an insulated center conductor with a braided metal shield. The metal shield helps to reduce electromagnetic interference and noise from external sources. Coaxial cables are commonly used for cable TV, radio, and broadband internet connections12.

Correct : B

A hub-and-spoke topology is a type of VPN topology that connects multiple remote offices to a central hub, usually the corporate head office, through VPN tunnels. The hub acts as a gateway for the remote offices to access the corporate network resources. However, the remote offices cannot communicate with each other directly, and have to go through the hub. This topology reduces the number of VPN tunnels required, but also increases the load and latency on the hub. In the scenario, John configured a central hub at the corporate head office, through which all branch offices can communicate, but denied communication between the remote offices. Therefore, the type of VPN topology implemented by John is hub-and-spoke12.

Correct : B

HitmanPro is a tool that is designed to identify and prevent malicious Trojans or malware from infecting computer systems or electronic devices. HitmanPro is a cloud-based malware scanner that can detect and remove various types of malware, such as viruses, ransomware, spyware, rootkits, etc. HitmanPro can also work alongside other antivirus programs and provide a second opinion on the security status of the system12.

Correct : A

RSA is a public-key cryptosystem that uses modular arithmetic and elementary number theory for Internet encryption and user authentication. RSA stands for Rivest-Shamir-Adleman, the names of the inventors of the algorithm. RSA allows users to generate a pair of keys, one public and one private, that are mathematically related. The public key can be used to encrypt messages or verify digital signatures, while the private key can be used to decrypt messages or create digital signatures. RSA is based on the difficulty of factoring large numbers, which makes it secure and widely used12.
