NEW QUESTION # 198
A production engineer is configuring a new application, which is running in containers, that requires access to a database. Which of the following methods will allow the application to authenticate to the database in the MOST secure way?
- A. Store the credentials using the orchestrator secret manager
- B. Store the credentials on a shared volume using whole-disk encryption
- C. Store the credentials in a configuration file using SHA-256 inside the container image
- D. Store the credentials in a variable on every worker node
Answer: A
Explanation:
The most secure way to store the credentials for a new application that is running in containers and requires access to a database is to use the orchestrator secret manager. The orchestrator secret manager is a feature that allows storing and managing sensitive data, such as passwords, tokens, or keys, for containers in an encrypted and centralized way. It also provides access control, auditing, and rotation features for the secrets. This method will protect the credentials from being exposed or compromised by unauthorized parties or malicious actors.

NEW QUESTION # 199
A technician deployed a VM with NL-SAS storage to host a critical application. Two weeks later, users have begun to report high application latency. Which of the following is the BEST action to correct the latency issue?
- A. Migrate the data to flash storage.
- B. Migrate the data to SAS storage.
- C. Increase the capacity of the data storage.
- D. Increase the CPU of the VM.
Answer: A
Explanation:
The correct answer is D. Migrate the data to flash storage. Flash storage is a type of solid-state storage that uses flash memory to store data. Flash storage has much faster performance and lower latency than NL-SAS storage, which is a type of hard disk drive that uses nearline serial attached SCSI interface. According to the web search results, NL-SAS devices have much higher response times than flash devices123. Therefore, migrating the data to flash storage can reduce the application latency and improve the user experience. Increasing the capacity of the data storage, migrating the data to SAS storage, or increasing the CPU of the VM are not likely to solve the latency issue, as they do not address the root cause of the problem, which is the slow performance of NL-SAS storage. For more information on flash storage and its benefits, you can refer to the Dell EMC Unity: FAST Technology Overview2 or the Dell Technologies website4.
NEW QUESTION # 200
A web-application company recently released some new marketing promotions without notifying the IT staff. The systems administrator has since been noticing twice the normal traffic consumption every two hours for the last three hours in the container environment. Which of the following should the company implement to accommodate the new traffic?
- A. Ballooning
- B. Switches
- C. Autoscaling
- D. A firewall
Answer: C
Explanation:
According to the CompTIA Cloud+ Study Guide1, autoscaling is "the ability to automatically increase or decrease the number of resources allocated to a cloud service based on the current demand". This means that autoscaling can help a cloud environment adjust to changes in traffic and workload, such as the ones caused by the new marketing promotions.
Ballooning, on the other hand, is "a technique used by hypervisors to reclaim unused memory from a virtual machine and allocate it to another virtual machine that needs more memory". This means that ballooning can help optimize the memory usage of a cloud environment, but it does not affect the number of resources allocated to a cloud service.
A firewall is "a device or software that monitors and controls the incoming and outgoing network traffic based on predefined rules". This means that a firewall can help protect a cloud environment from unauthorized access and malicious attacks, but it does not affect the number of resources allocated to a cloud service.
Switches are "devices that connect multiple devices on a network and forward data packets between them". This means that switches can help improve the network performance and connectivity of a cloud environment, but they do not affect the number of resources allocated to a cloud service.
Based on this information, I think the best answer to your question is D. Autoscaling. Autoscaling can help the company accommodate the new traffic by automatically increasing or decreasing the number of resources allocated to their web-application service based on the current demand. This can also help reduce costs and improve performance and availability.
I hope this helps you understand the concept of autoscaling better. If you want to learn more about CompTIA Cloud+, you can check out some of these resources:

NEW QUESTION # 201
Which of the following actions should a systems administrator perform during the containment phase of a security incident in the cloud?
- A. Deploy a new instance using a known-good base image.
- B. Conduct a tabletop exercise involving developers and systems administrators.
- C. Perform a forensic analysis of the affected instance.
- D. Configure a firewall rule to block the traffic on the affected instance.
Answer: D
Explanation:
Configuring a firewall rule to block the traffic on the affected instance is what the administrator should perform during the containment phase of a security incident in the cloud. A security incident is an event or situation that affects or may affect the confidentiality, integrity, or availability of cloud resources or data. A security incident response is a process of managing and resolving a security incident using various phases, such as identification, containment, eradication, recovery, etc. The containment phase is where the administrator tries to isolate and prevent the spread or escalation of the security incident. Configuring a firewall rule to block the traffic on the affected instance can help to contain a security incident by cutting off any communication or interaction between the instance and other systems or networks, which may stop any malicious or unauthorized activity or access.

NEW QUESTION # 206
A cloud administrator is troubleshooting an issue regarding users at one location who are reporting that their API access tokens have become invalid. The users are issued tokens based on their credentials in a federated cluster. Which of the following should the administrator check to determine the cause of this issue?
- A. SAML
- B. NTP
- C. DNS
- D. SSL
Answer: A
Explanation:
The answer is
A) SAML. SAML (Security Assertion Markup Language) is a standard for exchanging authentication and authorization data between different parties, such as a user and a service provider. In a federated cluster, SAML can be used to enable single sign-on (SSO) for users across multiple clusters or cloud providers. SAML relies on the exchange of XML-based assertions that contain information about the user's identity, attributes, and entitlements. If the users' API access tokens have become invalid, it could be because the SAML assertions have expired, been revoked, or corrupted. The administrator should check the SAML configuration and logs to determine the cause of this issue.
Some possible sources of information about SAML and federated clusters are:
Authenticating | Kubernetes: This page provides an overview of authenticating users in Kubernetes, including using SAML for federated identity.
Authenticating to the Kubernetes API server - Google Cloud: This page explains how to authenticate to the Kubernetes API server on Google Cloud, including using SAML for federated identity with Google Cloud Identity Platform.
