Question 1

After deploying a Virtual Private Cloud service, and configuring a routed network for your VM, you find that you are unable to access any ports assigned to services on the VM. What is most likely the issue?

Accepted Answer

The Edge Gateway might be blocking all incoming ports, preventing access to services on the VM.

Question 2

What is not one of the items defined by the control components of OpenStack?

Accepted Answer

Virtual machine image management is not a control component of OpenStack; it is a service provided by OpenStack's Glance component. The control components typically include API services, web interfaces, and identity management.

Question 3

What NIST defined cloud characteristic describes access to services over the network using a Web browser and standard interfaces from any location with a variety of devices including desktop, laptop, and tablet computers?

Accepted Answer

Broad network access is the NIST defined cloud characteristic that describes the ability to access services over the network using standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, tablets, laptops, and workstations).

Question 4

Elasticity is the NIST defined characteristic that allows resources to be managed by the consumer and quickly scaled out to provide more capability or quickly scaled in to release unneeded capacity and costs.

Accepted Answer

Elasticity is a key characteristic of cloud computing as defined by NIST, allowing resources to be dynamically allocated and deallocated based on demand, thus optimizing resource usage and cost.

Question 5

Both VMware vCloud and Microsoft Azure are generally classified as IaaS cloud platforms.

Accepted Answer

Both VMware vCloud and Microsoft Azure provide infrastructure as a service (IaaS), which means they offer virtualized computing resources such as servers, storage, and networks.

Question 6

No vCloud account is required in order to set up a vCloud virtual data center (VDC), although it is preferred.

Accepted Answer

A vCloud account is required to set up a vCloud Virtual Data Center (VDC) because it provides the necessary authentication and authorization to access and manage VMware's cloud infrastructure services.

Question 7

What hosts Web objects such as images and text as well as software and documents across a global network of high bandwidth servers?

Accepted Answer

A Content Delivery Network (CDN) is designed to host and deliver web objects, such as images, text, software, and documents, across a distributed network of servers to ensure high availability and performance.

Question 8

What is the amount of storage that is provided when using the vCloud Air Virtual Private Cloud starter pack resource?

Accepted Answer

The answer of What is the amount of storage that...

Question 9

How can you create a DMZ-like zone within a virtual data center using vCloud Air?

Accepted Answer

A DMZ (Demilitarized Zone) in a virtual data center can be created by using a combination of both routed and isolated networks. This setup allows for the separation of external-facing services from the internal network, enhancing security.

Question 10

Virtual Machine Manager can provide support for only a single private cloud.

Accepted Answer

Virtual Machine Manager (VMM) can manage multiple private clouds, not just a single one. It is designed to support and manage complex datacenter environments that may include multiple private clouds.

Question 11

What Azure File Storage replication strategy supports replication across multiple facilities as well as the ability to read data from primary or secondary locations?

Accepted Answer

RA-GRS (Read-Access Geo-Redundant Storage) supports replication across multiple facilities and allows data to be read from both the primary and secondary locations, providing both high availability and durability.

Question 12

What is the vCloud Air equivalent of the VMware NSX software defined networking environment?

Accepted Answer

Advanced Networking Services is the vCloud Air equivalent of the VMware NSX software-defined networking environment, providing similar capabilities in the cloud.

Question 13

Under what tab in the vRealize Automation dashboard will a user be able to deploy services that they have been entitled to?

Accepted Answer

The Catalog tab in the vRealize Automation dashboard is where users can deploy services that they have been entitled to. This tab displays the catalog items and services that are available for deployment based on the user's entitlements.

Question 14

What are the two different options available for connecting vCloud Air and your vSphere data center?

Accepted Answer

A connection can be made over the public Internet or an IPSec VPN can be utilized.

Question 15

What statement regarding the use of vCloud Air is accurate?

Accepted Answer

The dedicated cloud account is typically more expensive than the Virtual Private Cloud account because it offers dedicated resources, whereas the Virtual Private Cloud shares resources among multiple tenants.

Question 16

You are attempting to map a drive letter to a Microsoft Azure File Storage cloud share, but the attempt fails with errors. What is most likely the issue, given the problems presented?

Accepted Answer

The most common issue when facing errors while attempting to map a drive letter to a Microsoft Azure File Storage cloud share is that your ISP or router is blocking the use of port 445 outside your local network. Azure File Storage uses SMB protocol, which typically requires port 445 to be open for communication.

Question 17

A cloud-based disaster recovery service is known as what type of service?

Accepted Answer

Recovery as a Service (RaaS) is a cloud-based service that provides disaster recovery solutions, allowing businesses to recover their data and applications in the event of a disaster.

Question 18

What Microsoft Azure cloud service does not fall under the Security and Identity category?

Accepted Answer

Digital Rights Management (DRM) is not categorized under Security and Identity within Microsoft Azure services. It is more related to protecting copyrights and intellectual property in digital media, rather than directly managing security and identity aspects like the other services listed.

Question 19

What VMware vCloud suite component provides self service and policy based infrastructure, and provides on-demand cloud services to consumers through the use of catalogs?

Accepted Answer

VMware vRealize Automation is designed to automate the deployment and management of computing environments across a multi-vendor cloud environment. It enables self-service and policy-based provisioning of infrastructure, applications, and custom IT services through catalogs, making it the correct choice for providing on-demand cloud services to consumers.

Question 20

The Virtual Private Cloud service is a multi-tenancy service in that multiple organizations will share the same hardware that is logically divided into separate virtual data centers.

Accepted Answer

Virtual Private Cloud (VPC) services operate on a multi-tenancy model where the physical infrastructure is shared among multiple organizations, but each organization's data and resources are logically isolated in separate virtual environments, ensuring privacy and security.
