A company has decided to get multiple compliance and security certifications for its public cloud environment. However, the company has few staff members to handle the extra workload, and it has limited knowledge of the current infrastructure.
Which of the following will help the company meet the compliance requirements as quickly as possible?
A. DLP
B. CASB
C. FIM
D. NAC
Correct Answer: B
A cloud access security broker (CASB) is a type of security solution that acts as a gateway between cloud service users and cloud service providers. A CASB can help a company get multiple compliance and security certifications for its public cloud environment, as it can provide visibility, control, and protection for cloud data and applications. A CASB can also help the company handle the extra workload and overcome the limited knowledge of the current infrastructure, as it can automate and simplify the enforcement of security policies and compliance requirements across multiple cloud services.

Question 342:
Which of the following will mitigate the risk of users who have access to an instance modifying the system configurations?
A. Implement whole-disk encryption
B. Deploy the latest OS patches
C. Deploy an anti-malware solution
D. Implement mandatory access control
Correct Answer: D
Mandatory access control (MAC) is a type of access control model that enforces strict security policies based on predefined rules and labels. MAC assigns security labels to subjects (users or processes) and objects (files or resources) and allows access only if the subject has the appropriate clearance and need-to-know for the object. MAC can mitigate the risk of users who have access to an instance modifying the system configurations, as it can prevent unauthorized or accidental changes to critical files or settings by restricting access based on predefined rules and labels.

Question 343:
Which of the following service models would be used for a database in the cloud?
A. PaaS
B. laaS
C. CaaS
D. SaaS
Correct Answer: A
PaaS (Platform as a Service) is a cloud service model that provides a platform for developing, testing, deploying, and managing applications in the cloud. PaaS includes the underlying infrastructure (servers, storage, network, etc.) as well as the middleware, databases, tools, frameworks, and APIs that are required for application development and delivery. Examples of PaaS are AWS Elastic Beanstalk, Azure App Service, Google App Engine, etc.
Question 344:
An IaaS application has a two-hour RTO and a four-hour RPO. The application takes one hour to back up its data or restore from a local backup file. A systems administrator is tasked with configuring the backup policy.
Which of the following should the administrator configure to achieve the application requirements with the LEAST cost?
A. Back up to long-term storage every night
B. Back up to object storage every three hours
C. Back up to long-term storage every four hours
D. Back up to object storage every hour
Correct Answer: B
Object storage is a type of storage service that stores data as objects with unique identifiers and metadata in a flat namespace or structure. Backing up to object storage every three hours can help achieve the application requirements with the least cost for an IaaS application that has a two-hour RTO and a four-hour RPO, as it can provide scalable, durable, and cost-effective storage for backup data while meeting the recovery time and point objectives. Backing up to object storage every three hours can ensure that the backup data is no more than four hours old and can be restored within two hours in case of a disaster or failure.

Question 345:
A company is planning to migrate applications to a public cloud, and the Chief Information Officer (CIO) would like to know the cost per business unit for the applications in the cloud. Before the migration, which of the following should the administrator implement FIRST to assist with reporting the cost for each business unit?
A. An SLA report
B. Tagging
C. Quotas
D. Showback
Correct Answer: B
Tagging is what the administrator should implement first to assist with reporting the cost for each business unit for applications in a public cloud environment. Tagging is a technique that allows customers to assign metadata or labels to their cloud resources, such as applications, instances, volumes, etc., based on their attributes or criteria. Tagging can help customers to organize, manage, monitor, and report their cloud resources and costs by business unit, project, owner, environment, etc.
A cloud architect is designing the VPCs for a new hybrid cloud deployment. The business requires the following:
1.
High availability
2.
Horizontal auto-scaling
3.
60 nodes peak capacity per region
4.
Five reserved network IP addresses per subnet
5.
/24 range
Which of the following would BEST meet the above requirements?
A. Create two /25 subnets in different regions
B. Create three /25 subnets in different regions
C. Create two /26 subnets in different regions
D. Create three /26 subnets in different regions
E. Create two /27 subnets in different regions
F. Create three /27 subnets in different regions
Correct Answer: A
You need 65 IPs per region. /27 will only give you 32 and /26 will only give you 64. You need a /25 network which will give you 128 per region. Having two regions will give you the requirement of high availability. Yes, 3 regions is better than 2, but it doesn't ask for the best high availability option, it just asks for high availability which 2 regions provides.
Question 347:
A company is doing a cloud-to-cloud migration to lower costs. A systems administrator has to plan the migration accordingly.
Which of the following considerations is MOST important for a successful, future-proof, and low-cost migration?
A. Tier pricing
B. Licensing
C. Estimated consumption
D. Feature compatibility
Correct Answer: D
Feature compatibility is an important consideration for a successful cloud-to-cloud migration, as different cloud providers may have different features, services, APIs, and standards. If the application relies on specific features that are not available or compatible with the target cloud provider, the migration may fail or incur additional costs and complexity. The administrator should assess and compare the features of both cloud providers and ensure they meet the application requirements.
Question 348:
A systems administrator would like to reduce the network delay between two servers.
Which of the following will reduce the network delay without taxing other system resources?
A. Decrease the MTU size on both servers
B. Adjust the CPU resources on both servers
C. Enable compression between the servers
D. Configure a VPN tunnel between the servers
Correct Answer: A
The maximum transmission unit (MTU) is the largest size of a packet or frame that can be sent over a network. Decreasing the MTU size on both servers can reduce the network delay between them, as it can reduce the fragmentation and reassembly of packets, improve the transmission efficiency, and avoid packet loss or errors. Decreasing the MTU size can also avoid taxing other system resources, as it does not require additional CPU, memory, or disk resources.

A company is switching from one cloud provider to another and needs to complete the migration as quickly as possible.
Which of the following is the MOST important consideration to ensure a seamless migration?
A. The cost of the environment
B. The I/O of the storage
C. Feature compatibility
D. Network utilization
Correct Answer: C
Feature compatibility is the degree to which the features or functionalities of a system or application are compatible or interoperable with another system or application. Feature compatibility is the most important consideration to ensure a seamless migration from one cloud provider to another, as it can affect the performance, reliability, and security of the system or application in the new cloud environment. Feature compatibility can also help complete the migration as quickly as possible, as it can reduce or eliminate the need for reconfiguration, customization, or testing of the system or application after the migration.

Question 350:
Lateral-moving malware has infected the server infrastructure. Which of the following network changes would MOST effectively prevent lateral movement in the future?
A. Implement DNSSEC in all DNS servers
B. Segment the physical network using a VLAN
C. Implement microsegmentation on the network
D. Implement 802.1X in the network infrastructure
Correct Answer: B
Microsegmentation is a type of network security technique that divides a network into smaller logical segments or zones based on workload or application characteristics and applies granular policies and rules to control and isolate traffic within each segment or zone. Implementing microsegmentation on the network can help prevent lateral movement in the future after lateral-moving malware has infected the server infrastructure, as it can limit the exposure and spread of malware by restricting access and communication between different segments or zones based on predefined criteria such as identity, role, or behavior.
