Lesson 3: Administering Cloud Resources Flashcards
What type of cloud service is Microsoft Office 365?
A.SaaS
B.PaaS
C.IaaS
D.STaaS
A.SaaS
Microsoft Office 365 uses a Software as a Service (SaaS) subscription in the cloud. The consumer has direct use of the software, and responsibility for the hardware, operating system (OS), installation, and patching of the software is offloaded to the cloud service provider (CSP).
If a host begins claiming memory normally reserved for virtual machines, what is the likely indication?
A.Anomalies
B.Auto-scaling
C.The host is running out of memory
D.Load balancing
C.The host is running out of memory
If a host is depleting its memory, it may start ballooning. Memory ballooning reclaims memory not being used by virtual machines.
A virtual instance on the Amazon Web Services (AWS) platform has 64 virtual central processing units (vCPUs) and 432 (Gibibyte) GiB of memory. What can a cloud administrator do to make the virtual instance memory-optimized? (Select all that apply.)
A.Change virtual instance type.
B.Reduce vCPU count.
C.Power off virtual instance.
D.Use a hyperconverged system.
A.Change virtual instance type.
C.Power off virtual instance.
A system administrator must change the instance type of a virtual instance in AWS to change the amount of memory. Make this change from the AWS Management Console.
A system administrator must power down the virtual instance on AWS to change its instance type. The virtual instance will immediately recognize the new compute resources after it is powered on.
How does a host machine recognize the data in memory used by virtual machines?
A.It auto-configures swapping
B.It doesn’t perceive it
C.It is seen as separate
D.It hyperconverges
B.It doesn’t perceive it
Once a host system maps the memory to the virtual machines, the system becomes unaware of how the VMs manage the memory or what information is stored there.
An organization has asked a network administrator to configure a departmental network that includes both storage and virtualization capabilities. The department maintains its own internal IT staff capable of managing the configuration, but it should come ready to deploy immediately across the entire department. What is the organization asking the administrator to configure?
A.Solution template
B.Container
C.Serverless deployment
D.Managed template
A.Solution template
Solution templates describe a complete template that includes multiple virtual servers, various services, and network configurations. Following deployment, the consumer will manage the structure themselves.
A systems administrator is troubleshooting a newly launched database that cannot access its storage. The database drew its original configuration from a similar database, using the same base image file. Which of the following is the most likely reason the database is experiencing these issues?
A.Faulty image
B.Improperly configured variable
C.Storage location configured as a secret
D.Faulty VM template
B.Improperly configured variable
Variables, in this case, an environmental variable, direct storage placement. Once set up has occurred but still points to the location used by the other database, this would create an error
A cloud administrator receives a request to create a virtual instance on the Amazon Web Services (AWS) platform. The request explains that the virtual instance will perform various machine learning tasks for a new web application. What type of instance would the cloud administrator most likely create for this request?
A.General purpose
B.Memory optimized
C.Compute optimized
D.Storage optimized
C.Compute optimized
AWS compute optimized instances such as C6g, C6gd, C6gn, are usually selected for high-performance web servers, machine learning, video encoding, and dedicated game servers. Instances are configured based on their intended role.
A server technician is testing new processing hardware to use in a private cloud deployment. What is the technician measuring to determine overall performance? (Select all that apply.)
A.RPM
B.IPC
C.GHz
D.Hyperconvergence
B.IPC
C.GHz
Instructions per cycle (IPC), or clock speed, is a common performance measurement for CPUs. The calculation for IPC is the average number of instructions executed per clock cycle.
When dealing with CPUs, Gigahertz (GHz) represents a cycle of time and is the specific measurement unit when registering clock speed.
A technical department is preparing to expand its virtualized environment. After configuring the initial virtual machine (VM) with all necessary applications and settings, they wish to replicate this VM’s exact state on the new servers being added. What would be the most efficient method to replicate this VM’s exact configuration across the added servers?
A.VM templates
B.Software patches
C.Clones
D.OS templates
C.Clones
Cloning is the process of creating an exact copy of a virtual machine. By cloning the initial VM, the technical department can quickly replicate its exact state across the newly added servers, ensuring each VM has the same applications and settings. This is an efficient way to duplicate a specific VM’s configuration, especially when the goal is to reproduce the VM’s current state on multiple servers.
A virtual machine fails to utilize memory resources it normally uses during a certain time of day, and as a result, initiates a memory swap. What is most likely causing this remedial action?
A.Ballooning
B.Paging
C.Hyperthreading
D.Hyperconvergence
A.Ballooning
Memory ballooning is a feature of hypervisors designed to make more efficient use of physical memory for virtual servers by reclaiming memory currently unused by the VMs. When the VM reaches back for the unavailable memory, swapping may occur if configured.
An AWS technician is utilizing a remote desktop to investigate a company’s internal application that is experiencing bug-like symptoms. Which tool would allow workstations used by the app users to accept any patches or updates, following the technician fixing any discovered issues?
A.Kerberos
B.NFS
C.WorkDocs
D.Workspaces
D.Workspaces
AWS WorkSpaces is a cloud-based virtual desktop infrastructure (VDI) capable of replacing conventional desktops. The AWS technician would deploy new patches only on the centralized server, and any desktop instance launched will include the update.
An application developer would like to work on new versions for a recent gaming app release. To streamline operations, the developer will use a separate virtual machine (VM) from their primary VM due to better sound and graphics quality. Which of the following options would facilitate better performance while remaining at a relatively cheap price?
A.Pass-through vGPU
B.VPC
C.Shared vGPU
D.SDN
C.Shared vGPU
Shared Virtual Graphics Processing Units (vGPUs) contain a single physical GPU and are available to multiple VMs. This provides a cheaper option, but the administrator must ensure the host GPU is adequate in serving the VMs.
The company purchased a cloud-based application that all employees can access from a web browser. The application will be able to support new employees as the company grows. What type of licensing structure did the company most likely purchase for this application?
A.Socket based licensing
B.Per user licensing
C.Volume based licensing
D.Perpetual licensing
B.Per user licensing
A per user licensing is a single license for each user that consumes the software or service. These subscriptions are usually sold in batches like 100 or 500 user options.
An administrator is installing Linux to test the new version of an operating system on their desktop. What will the administrator most likely deploy?
A.Type 1 Hypervisor
B.Type 2 Hypervisor
C.VM Template
D.DMZ
B.Type 2 Hypervisor
Type 2 hypervisors run as applications on a host operating system and are more common for workstation or developer deployments than production servers.
Type 1 hypervisors are faster than type 2. They install directly on the hardware without having to go through a configuration layer. In this deployment, there is not a host operating system.
Which of the following provides additional servers, either virtual or physical, to support increased demand? (Select all that apply.)
A.Scaling up
B.Vertical scaling
C.Horizontal scaling
D.Scaling out
C.Horizontal scaling
D.Scaling out
Horizontal scaling, also known as scaling out, provides additional servers, either virtual or physical, to support increased workloads. For example, a website hosted by three web servers (which are web-based VM instances) might suddenly be hosted on five servers if demand spikes.
Scaling out, another term for horizontal scaling, adds more instances in support of increased workloads.
Scaling up adds compute resources to existing virtual machine instances. It is also known as vertical scaling.
Vertical scaling also adds additional compute capabilities to existing virtual machines to meet an increased need. It is also known as scaling up
