Deploying two firewalls in a HA (High Availability) configuration is the best option to ensure all traffic passes through the firewall and meets the SLA (Service Level Agreement) of 99.999%. HA is a design principle that aims to minimize downtime and ensure continuous operation of a system or service. HA can be achieved by using redundancy, failover, load balancing, clustering, etc. Two firewalls in a HA configuration can provide redundancy and failover in case one firewall fails or becomes overloaded.

The fastest way to restore the service after deploying a new application release to the green stack of a blue-green infrastructure model and making the green stack primary is to failback to the blue stack. Failing back means switching back to the previous version of the application that is running on the blue stack, which is still available and functional. This will minimize the downtime and impact on the users, while allowing the systems administrator to troubleshoot and fix the issues on the green stack.

The correct answer is C. NTP.

NTP stands for Network Time Protocol, which is a standard protocol for synchronizing the clocks of computers over a network. NTP uses a hierarchical, client-server architecture, where a client requests the current time from a server, and the server responds with a timestamp. The client then adjusts its own clock to match the server’s time, taking into account the network delay and clock drift. NTP can achieve sub-millisecond accuracy over local area networks and a few milliseconds over the internet12.

NTP can help maintain time synchronization between all the resources in a distributed cloud environment, as it allows each resource to get the accurate time from a reliable source. This can help with correlating logs, auditing, security, and other time-sensitive operations. NTP can also handle different time zones, as it uses Coordinated Universal Time (UTC) as the reference time, and each resource can convert UTC to its local time zone12.

DNS stands for Domain Name System, which is a protocol for resolving domain names into IP addresses. DNS does not provide any functionality for time synchronization3.

IPAM stands for IP Address Management, which is a method for planning, tracking, and managing the IP address space used in a network. IPAM does not provide any functionality for time synchronization.

SNMP stands for Simple Network Management Protocol, which is a protocol for collecting and organizing information about managed devices on a network. SNMP can be used to monitor the performance, availability, configuration, and security of network devices, but it does not provide any functionality for time synchronization.

A PaaS solution, or platform as a service, is a cloud computing service that provides a complete, ready-to-use, cloud-hosted platform for developing, running, maintaining and managing applications1. A PaaS solution would meet the company’s goal of maximizing scalability, availability, and security, while requiring no infrastructure administration, because:

Scalability: A PaaS solution can automatically scale up or down the resources needed to run the application based on the demand and traffic. The company does not need to worry about provisioning or managing servers, storage, network, or load balancers23.

Availability: A PaaS solution can ensure high availability and reliability of the application by replicating it across multiple regions and zones. The company does not need to worry about backup, recovery, or failover23.

Security: A PaaS solution can provide built-in security features such as encryption, authentication, authorization, and firewall. The company does not need to worry about installing or updating security patches or software23.

No infrastructure administration: A PaaS solution can abstract away the underlying infrastructure and hardware from the company. The company only needs to focus on developing and deploying the application code and data. The PaaS provider takes care of the rest23.

A hybrid solution (B) is a cloud computing service that combines on-premises and cloud resources. It may offer some benefits such as flexibility and cost optimization, but it would not meet the company’s goal of requiring no infrastructure administration. The company would still need to manage and maintain the on-premises part of the solution4.

Tags are key-value pairs that can be applied to cloud resources to organize, categorize, and filter them. Tags can also be used to assign resources to backup jobs based on their RPO requirements. The cloud engineer forgot to configure the appropriate tag for the new VM that matches the text-based variable of the backup platform. Therefore, the backup platform did not add the VM to the correct job. References: Tags and labels | Cloud Storage | Google Cloud, CompTIA Cloud+ Certification Exam Objectives, Domain 4.0: Operations and Support, Objective 4.3: Given a scenario, apply the appropriate methods for cost control in a cloud environment.
