QUESTION: 77

A client want to secure virtual server instance (VSI) as soon as it is provisioned in Virtual Private Cloud (VPC) environment and control the traffice that passes through the VSI. Which option will accomplish this?

Order a load balancer with the VSI
Configure security groups before ordering the VSI
Order transit gateway with the VSI
Configure security groups after ordering the VSI

Answer(s): D

Explanation:

You can use security groups to enact a set of IP filter rules that define how to handle incoming and outgoing traffic to both the public and private interfaces your instance. Use security groups when you order a virtual server. That way, your server is protected when it is first provisioned. Other Scenarios with solutions listed below:
1. Security scenario: Customers want granular control over traffic at an instance level (apart from network-level firewalls). However, at the same time, the costs of a shared hardware firewall can add up quickly if you need to protect multiple servers in different data centers. Solution: You do not incur extra charges for using security groups. You can use security groups for all virtual servers that need protection in any of our global data centers.
2. Security scenario: You want to avoid configuring firewall rules on each server separately. Instead, you want an easily manageable firewall solution that spans servers in different global data centers. Solution: Define N security groups for N different types of servers in your cloud workload. Manage all rules for a security group in one place. Manage the security group associations with the virtual servers.

Which of the following statement best describe Multi Cloud?

The use of two or more clouds from different cloud providers
The use of three or more clouds from different cloud providers
The use of hybrid cloud from a cloud providers
The use of private and public cloud from a cloud providers

Answer(s): A

Explanation:

Multi Cloud is a combination of two or more cloud services from different cloud providers. Incorrect Answers:
Private Cloud:
The cloud infrastructure is provisioned for exclusive use by a single organization comprising multiple consumers (e.g., business units). It may be owned, managed, and operated by the organization, a third party, or some combination of them, and it may exist on or off premises. Community Cloud:
The cloud infrastructure is provisioned for exclusive use by a specific community of consumers from organizations that have shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be owned, managed, and operated by one or more of the organizations in the community, a third party, or some combination of them, and it may exist on or off premises. Public Cloud:
The cloud infrastructure is provisioned for open use by the general public. It may be owned, managed, and operated by a business, academic, or government organization, or some combination of them. It exists on the premises of the cloud provider. Hybrid Cloud:
The cloud infrastructure is a composition of two or more distinct cloud infrastructures (private, community, or public) that remain unique entities, but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load balancing between clouds).

What is another name given to a Type 2 hypervisor?

Hosted
Virtual Machine
Single tenant
Bare Metal Server

Answer(s): A

Explanation:

Correct Answer:
Hypervisor is a small software layer that enables multiple operating systems to run alongside each other. Hypervisor separates the VMs logically, assigning each its own slice of underlying computing power, memory, and storage. There are 2 types of Hypervisor:
Type 1 & Type 2. Hosted is another name given to a Type 2 hypervisor. Type 2 Hypervisors:
Run as an application in a host operating system, rather than in place of an operating system Create a virtual machine and install a guest operating system on it Assign physical resources to a virtual machine and set the amount of processor cores and memory it can use Known as "hosted" Mostly used for end-user virtualization, less frequently used, higher latency Some examples are Oracle VirtualBox and VMware Workstation Incorrect Answers:
Virtual Machine:
A virtual machine is a virtual representation of physical computer, that behaves like an actual computer. Single Tenant:
Sigle tenant means, used by single organization only. Bare metal server are single-tenant physical servers that are dedicated to a single customer. Bare metal servers fulfill the demanding needs of high-performance computing (HPC) and data intense applications. Use cases:
Bare metal server are suitable for CPU and I/O intensive workloads.
