In support of disaster recovery objectives, a third party agreed to provide 99.999% uptime. Recently, a hardware failure impacted a firewall without service degradation. Which of the following resiliency concepts was most likely in place?
High availability ensures continuous operation despite hardware failures by leveraging redundant components like clustered firewalls or failover systems. This aligns with CASP+ objective 3.1, which focuses on implementing availability and redundancy mechanisms in disaster recovery planning.

An organization has deployed a cloud-based application that provides virtual event services globally to clients. During a typical event, thousands of users access various entry pages within a short period of time. The entry pages include sponsor-related content that is relatively static and is pulled from a database. When the first major event occurs, users report poor response time on the entry pages. Which of the following features is the most appropriate for the company to implement?
Caching is the most appropriate solution to improve response time for static content, such as sponsor-related data on the entry pages. Caching stores frequently accessed data closer to users, reducing the need to retrieve it from the database repeatedly. This results in faster load times, especially during high-traffic events. While scalability (horizontal or vertical) might address overall system performance, caching specifically targets improving the speed of accessing static content. CASP+ emphasizes caching as a performance optimization technique for handling high-demand, static web content.

A company reviews the regulatory requirements associated with a new product, and then company management elects to cancel production. Which of the following risk strategies is the company using in this scenario?
In this scenario, the company has elected to cancel the production of a product after reviewing regulatory requirements. This decision reflects a risk avoidance strategy, which involves taking action to eliminate exposure to a risk by not engaging in the activity that could lead to it. By canceling production, the company avoids the regulatory and compliance risks altogether. CASP+ defines risk avoidance as a risk management strategy that involves stopping or avoiding actions that expose the organization to unacceptable levels of risk.

A security administrator needs to implement a security solution that will
* Limit the attack surface in case of an incident
* Improve access control for external and internal network security.
* Improve performance with less congestion on network traffic
Which of the following should the security administrator do?
Updating firewall rules to match new IP addresses in use will help to limit the attack surface in case of an incident by ensuring only legitimate traffic is allowed. It can also improve access control for external and internal network security by ensuring that only authorized entities can access certain resources, and may improve network performance by reducing unnecessary traffic (less congestion).
A technician accidentally deleted the secret key that was corresponding to the public key pinned to a busy online magazine. To remedy the situation, the technician obtained a new certificate with a different key. However, paying subscribers were locked out of the website until the key-pinning policy expired. Which of the following alternatives should the technician adopt to prevent a similar issue in the future?
Certificate Authority Authorization (CAA) is not listed directly in the provided options, but it is a relevant mechanism in the context of managing certificates and preventing issues similar to the one described. However, based on the available choices, the Online Certificate Status Protocol (OCSP) comes closest to providing a viable solution. OCSP allows for real-time validation of a certificate's revocation status, which could mitigate the issue of users being locked out due to key pinning policies. It is a more modern and efficient alternative to Certificate Revocation Lists (CRLs), offering faster and more reliable certificate status checks. By implementing OCSP, the technician could ensure that clients receive timely updates on the revocation status of certificates, potentially avoiding the downtime caused by the key-pinning policy awaiting expiration.
