Question 1
A cloud administrator is designing an environment that must remain
operational if an entire availability zone becomes unavailable. The
application consists of stateless web servers, an application tier, and a
database. Which architecture BEST satisfies the availability
requirement?
A. Place all components in one availability zone and create nightly
backups
B. Deploy redundant application components across multiple availability
zones and use a load balancer
C. Place all components on a single high-performance virtual machine
D. Deploy the database on local storage and replicate backups weekly
Answer: B. Deploy redundant application components across
multiple availability zones and use a load balancer
Rationale: Deploying redundant components across availability zones
removes the availability-zone failure as a single point of failure. A load
balancer distributes traffic among healthy instances, allowing the
application to continue operating when one zone or instance fails.
Backups alone do not provide the immediate availability required.
Question 2
1
,A company wants to move an existing application from an on-premises
virtualization cluster to a cloud environment with minimal modification.
The company wants to continue managing the operating system and
application while the cloud provider manages the underlying physical
infrastructure. Which cloud service model is MOST appropriate?
A. SaaS
B. PaaS
C. IaaS
D. DaaS
Answer: C. IaaS
Rationale: Infrastructure as a Service provides virtualized compute,
storage, and networking while allowing the customer to manage the
operating system and applications. PaaS would shift additional
management responsibilities to the provider, while SaaS would provide
a complete application rather than infrastructure.
Question 3
A cloud administrator notices that several virtual machines have
significantly different CPU utilization patterns. Some experience
sustained utilization above 90%, while others remain below 10%. Which
action would BEST improve resource utilization?
A. Increase the storage capacity of every VM
B. Implement workload monitoring and right-size the VMs
C. Disable CPU monitoring
D. Increase the number of static IP addresses
Answer: B. Implement workload monitoring and right-size the VMs
Rationale: Right-sizing matches allocated resources to actual
workload requirements. Oversized VMs waste resources and increase
cost, while undersized VMs can cause performance problems.
2
,Monitoring provides the utilization data necessary to make an
informed sizing decision.
Question 4
An organization wants its cloud environment to automatically increase
the number of application instances when CPU utilization exceeds a
predefined threshold and reduce the number when demand decreases.
What technology BEST provides this capability?
A. Static provisioning
B. Auto-scaling
C. Manual failover
D. RAID
Answer: B. Auto-scaling
Rationale: Auto-scaling automatically adjusts the number of compute
resources according to workload demand. Scale-out adds instances
when demand increases, while scale-in removes unnecessary instances
when demand decreases.
Question 5
A cloud engineer needs to ensure that a workload can tolerate the failure
of one virtual machine without interrupting service. Which design
principle should be prioritized?
A. Resource pooling
B. Redundancy
C. Data compression
D. Vertical fragmentation
Answer: B. Redundancy
3
, Rationale: Redundancy provides duplicate or alternative resources
that can continue serving workloads when a component fails. High-
availability architectures commonly use redundant servers, network
paths, storage systems, and other components.
Question 6
A company uses a cloud provider and wants its developers to deploy
applications without managing operating systems, virtual machines, or
physical servers. Which service model BEST meets this requirement?
A. IaaS
B. PaaS
C. Colocation
D. Bare metal
Answer: B. PaaS
Rationale: Platform as a Service abstracts infrastructure and
operating-system management while providing developers with a
managed application platform. Developers can concentrate on
application development and deployment rather than maintaining the
underlying infrastructure.
Question 7
An organization wants to prevent a compromised cloud workload from
communicating with unrelated application tiers. Which network security
mechanism would BEST accomplish this?
A. Network segmentation
B. Disk deduplication
C. CPU overcommitment
D. Snapshot scheduling
