Speaker 1: Welcome to Objective 3.4. In this video, we'll explain the importance of resilience and recovery in security architecture. We'll discuss how building robust systems and preparing for incidents ensures business continuity, quick recovery, and minimal downtime during security breaches. Let's explore how resilience strengthens your overall security posture. Question 1. What is a key benefit of using a multi-cloud system? A. Lower costs B. Faster data retrieval C. Reduce dependency on a single cloud service provider

Speaker 2: D. Easier management

Speaker 1: The answer is C. Reduce dependency on a single cloud service provider. The primary benefit of using a multi-cloud system is to reduce dependency on a single cloud service provider migrating risks such as downtime and security issues. Question 2. What does COOP address? A. Natural disaster only B. Cybersecurity attacks only C. An all-hazards approach to emergencies D. Only alternate facility setup The answer is C. An all-hazards approach to emergencies. COOP addresses emergencies from an all-hazards approach so it is applicable to a broad range of circumstances. Question 3. What is the focus of technology and capacity planning? A. People and staffing only B. Computational power, software, and hardware C. Infrastructure planning only D. Future cloud storage needs The answer is B. Computational power, software, and hardware. Technology capacity planning focuses on the computational power, software, and hardware needed to meet future organizational demands. Question 4. What do tabletop exercises aim to validate and improve? A. Incident response plan B. Software code quality C. Infrastructure resilience D. Staffing efficiency The answer is A. Incident response plan. Tabletop exercises are used to validate and improve an organization's incident response plan, IRP. Question 5. Which type of redundant site is near-duplicate of the original site and can be up and running within minutes? A. Hot site B. Warm site

Speaker 2: C. Cold site D. Tape-based backup site The answer is A. Hot site.

Speaker 1: A hot site is a near-duplicate of the original site and can be up and running within minutes. A company uses a hot site if would face financial ruin if its primary site became inaccessible for even a short period. Question 6. Which type of redundant site do organizations commonly choose because it offers a balance between configuration and cost? A. Hot site B. Warm site

Speaker 2: C. Cold site D. Tabletop exercise The answer is B. Warm site.

Speaker 1: A warm site offers a good amount of configuration yet remains less expensive than a hot site. It might need to have backups of data restored and may require some setup before it can be used. Question 7. What does an on-site backup strategy offer as a benefit? A. Protection against local disasters B. Fast access to backups for quick recovery

Speaker 2: C. Encryption D. Real-time data vulnerability

Speaker 1: The answer is B. Fast access to backups for quick recovery. The primary benefit of an on-site backup strategy is fast access to backups for quick recovery. Question 8. What is the purpose of an uninterruptible power supply? UPS A. To provide a permanent solution for power failures B. To convert mechanical energy into electrical energy C. To provide near-instantaneous protection from input power D. To replace the main power source The answer is C. To provide near-instantaneous protection from input power. A UPS provides near-instantaneous protection from input power interruptions by supplying energy stored in batteries or supercapacitors. Question 9. What is the primary difference between load balancing and clustering in the context of high availability? A. Load balancing distributes traffic whereas clustering combines multiple servers into one. B. Load balancing is for planned outages whereas clustering is for unplanned outages. C. Load balancing is used in cloud computing whereas clustering is used on-premises environments. D. Load balancing enhances system availability whereas clustering focuses on business continuity. The answer is A. Load balancing distributes traffic whereas clustering combines multiple servers into one. The primary difference is that load balancing distributes incoming network or application traffic across multiple servers to enhance system availability whereas clustering connects multiple servers to function as a single system contributing to recovery by allowing for seamless failover. Question 10. What is the primary reason for implementing platform diversity in an organization's IT environment? A. To reduce costs by using multiple vendors. B. To reduce systemic risks associated with a single point of failure. C. To improve performance by using specialized hardware and software from only a single vendor. D. To simplify management by using a variety of platforms. The answer is B. To reduce systemic risks associated with a single point of failure. The primary reason for implementing platform diversity is to reduce systemic risks resulting from having a single point of failure. By diversifying platforms, an organization increases its resilience and enhances its ability to recover from security incidents and technical failures. Thanks for watching.
