CV0-003 Exam Dumps - CompTIA Cloud+ Certification Exam

LTS (Long Term Support) is the update branch that the administrator should choose to ensure the system receives updates that are maintained for at least four years. An update branch is a category or group of updates that have different characteristics or features, such as frequency, stability, duration, etc. An update branch can help customers to choose the type of updates that suit their needs and preferences. LTS is an update branch that provides updates that are stable, reliable, and secure, and are supported for a long period of time, usually four years or more. LTS can help customers who value stability and security over new features or functions, and who do not want to change or upgrade their systems frequently.

Renewing the expired certificate is what would most likely resolve the issue of users receiving a message indicating the connection is not secure when landing on a website that is hosted on a cloud platform and accessed through https://www.comptiasite.com. A certificate is a digital document that contains information such as identity, public key, expiration date, etc., that can be used to prove one’s identity and establish secure communication over a network. A certificate can expire when it reaches its validity period and needs to be renewed or replaced. An expired certificate can cause users to receive a message indicating the connection is not secure by indicating that the website’s identity or security cannot be verified or trusted. Renewing the expired certificate can resolve the issue by extending its validity period and restoring its identity or security verification or trust.

Implementing an application whitelisting policy is the best way to prevent users from running malware on several IaaS compute instances. Application whitelisting is a security technique that allows only authorized or trusted applications to run on a system or device, and blocks or restricts all other applications. Application whitelisting can prevent users from running malware or unwanted software on their cloud instances, as well as reduce the attack surface and vulnerabilities of the system.

SR-IOV (Single Root Input/Output Virtualization) is what would best satisfy the requirements of low-latency, near-native performance of a physical NIC and data protection between VMs for multiple network I/O-intensive VMs. SR-IOV is a technology that allows a physical NIC to be partitioned into multiple virtual NICs that can be assigned to different VMs. SR-IOV can provide the following benefits:

Low-latency: SR-IOV can reduce latency by bypassing the hypervisor and allowing direct communication between the VMs and the physical NIC, without any overhead or interference.

Near-native performance: SR-IOV can provide near-native performance by allowing the VMs to use the full capacity and functionality of the physical NIC, without any emulation or translation.

Data protection: SR-IOV can provide data protection by isolating and securing the network traffic between the VMs and the physical NIC, without any exposure or leakage.

Hardening is the best option to help the cloud provider secure the environment and limit consumers’ activity on its IaaS platform. Hardening is a process of reducing the attack surface and vulnerabilities of a system or device by applying security configurations, patches, updates, policies, rules, etc. Hardening can prevent consumers from installing unauthorized or unsupported software on their cloud servers, such as hypervisors.

IPAM (IP Address Management) is what the administrator will most likely use to select an address for the new VM that is about to be deployed to a cloud environment. IPAM is a tool or service that allows customers to plan, track, and manage the IP addresses and DNS names of their cloud resources or systems. IPAM can help to select an address for the new VM by providing information such as available IP addresses, IP address ranges, subnets, domains, etc., as well as ensuring that the address is unique and valid.

The wrong gateway is the most likely cause of the connectivity issue for the new VM that cannot access the Internet or the VMs on any other subnet. A gateway is a device or software that connects two or more networks and routes traffic between them. A gateway is usually configured as the default route for a network device, which means that any traffic that is not destined for the local network will be sent to the gateway. If the gateway is configured incorrectly, the network device will not be able to communicate with other networks or the Internet. In this case, the new VM has an IP address of 172.16.31.40/24, which means that its subnet mask is 255.255.255.0 and its network ID is 172.16.31.0. However, its gateway is configured as 172.16.30.1, which belongs to a different network (172.16.30.0/24). This means that the new VM will not be able to reach its gateway or any other network through it. The administrator should change the gateway to an IP address that belongs to the same network as the new VM, such as 172.16.31.1 or 172.16.31.254.

Ordering a direct link to the provider is the fastest solution to resolve the issue of slow response times from an intranet website that is hosted on a cloud platform. A direct link is a dedicated, high-bandwidth, low-latency connection between the customer’s network and the cloud provider’s network. It bypasses the public internet and provides better performance, security, and reliability. Examples of direct links are AWS Direct Connect, Azure ExpressRoute, Google Cloud Interconnect, etc.
