A systems administrator is troubleshooting issues with network slowness. Traffic analysis shows that uplink bandwidth on the core switch is often sustained at 125Mbps due to a combination of production traffic from other sources. Which of the following would BEST resolve the issue?
- A. Enable QoS to prioritize production traffic.
- B. Increase the buffer size on the core switch.
- C. Turn off the servers that use the most bandwidth.
- D. Reboot the core switch.
Answer: A
Explanation:
Explanation
The best solution to resolve the issue of network slowness caused by high uplink bandwidth utilization on the core switch is to enable quality of service (QoS) to prioritize production traffic over other types of traffic. QoS is a mechanism that allows network administrators to classify and manage network traffic according to its importance, latency, bandwidth, and reliability requirements. By enabling QoS, the core switch can allocate more resources and guarantee better performance for production traffic, while limiting or dropping less critical traffic.

NEW QUESTION # 145
A cloud administrator recently deployed an update to the network drivers of several servers. Following the update, one of the servers no longer responds to remote login requests. The cloud administrator investigates the issue and gathers the following information:
The cloud management console shows the VM is running and the CPU and memory utilization is at or near 0%.
The cloud management console does not show an IP address for that server.
A DNS lookup shows the hostname resolves to an IP address.
The server is a member of the same security group as the others.
The cloud administrator is able to log in remotely to the other servers without issue.
Which of the following is the MOST likely cause of the server being unavailable?
- A. The network driver updates did not apply successfully, and the interface is in a down state.
- B. The update caused an increase in the output to the logs, and the server is too busy to respond.
- C. The server was assigned a new IP address, and DNS entry for the server name was not updated.
- D. The ACL policy for the server was updated as part of the server reboot, preventing login access.
Answer: C
NEW QUESTION # 146
A cloud security analyst needs to ensure the web servers in the public subnet allow only secure communications and must remediate any possible issue. The stateful configuration for the public web servers is as follows:
Which Of the following actions Should the analyst take to accomplish the Objective?
- A. Remove rules I, 2. and 5.
- B. Remove rules 2.3. and 4.
- C. Remove rules 3.4. and 5.
- D. Remove rules I, 3, and 4.
Answer: D
Explanation:
Explanation
The correct answer is B. Remove rules 1, 3, and 4.
The objective is to ensure the web servers in the public subnet allow only secure communications. This means that only HTTPS traffic should be allowed on port 443, which is the standard port for secure web connections.
HTTPS traffic uses the TCP protocol and encrypts the data between the client and the server.
Rule 1 allows all TCP traffic on any port from any source. This is too permissive and exposes the web servers to potential attacks or unauthorized access. Rule 1 should be removed to restrict the TCP traffic to only port
443.
Rule 3 allows all UDP traffic on any port from any source. UDP is a connectionless protocol that does not guarantee reliable or secure delivery of data. UDP is typically used for streaming media, voice over IP (VoIP), or online gaming, but not for web servers. Rule 3 should be removed to prevent unnecessary or malicious UDP traffic.
Rule 4 allows all ICMP traffic from any source. ICMP is a protocol that is used for diagnostic or control purposes, such as ping or traceroute. ICMP traffic can be used by attackers to scan or probe the network for vulnerabilities or information. Rule 4 should be removed to block ICMP traffic and reduce the attack surface.
Rule 2 allows TCP traffic on port 443 from any source. This is the desired rule that allows secure web communications using HTTPS. Rule 2 should be kept.
Rule 5 denies all other traffic that does not match any of the previous rules. This is the default rule that provides a catch-all protection for the web servers. Rule 5 should be kept.
Therefore, the analyst should remove rules 1, 3, and 4 to accomplish the objective.
NEW QUESTION # 147
A cloud architect wants to minimize the risk of having systems administrators in an IaaS compute instance perform application code changes. The development group should be the only group allowed to modify files in the directory.
Which of the following will accomplish the desired objective?
- A. Restrict the file write permissions to the development group only.
- B. Remove the file write permissions for the application service account.
- C. Deny access to all development user accounts
- D. Add access to the fileshare for the systems administrator's group.
Answer: A
Explanation:
Explanation
File write permissions are permissions that control who can modify or delete files in a directory or system.
Restricting the file write permissions to the development group only can help minimize the risk of having systems administrators in an IaaS compute instance perform application code changes, as it can prevent anyone other than the development group from altering or removing any files in the directory where the application code is stored. Restricting the file write permissions can also help maintain consistency and integrity, as it can ensure that only authorized and qualified users can make changes to the application code.

NEW QUESTION # 148
A systems administrator swapped a failed hard drive on a server with a RAID 5 array. During the RAID resynchronization, a second hard drive failed.
Which of the following actions will make the server fully operational?
- A. Swap the failed hard drive with a fresh one
- B. Perform a P2V migration of the server
- C. Restore the server from backup
- D. Restart the RAID resynchronization process
Answer: C
Explanation:
RAID 5 is a disk array configuration that uses parity to provide fault tolerance and data recovery. RAID 5 can tolerate the failure of one disk, but not two or more disks. If a second disk fails during the resynchronization process, the data on the RAID 5 array will be lost and unrecoverable. The only way to make the server fully operational is to restore the data from a backup source.

NEW QUESTION # 150
A systems administrator received an email from a cloud provider stating that storage is 80% full on the volume that stores VDI desktops. Which of the following is the MOST efficient way to mitigate the situation?
- A. Replication
- B. Deduplication
- C. Storage migration
- D. Compression
Answer: B
Explanation:
Deduplication is a technique that reduces the amount of storage space required by eliminating duplicate or redundant data blocks. Deduplication can be performed at the file level, where entire files are compared and removed if they are identical, or at the block level, where chunks of data within a file are compared and removed if they are identical. Deduplication can be especially effective for VDI (Virtual Desktop Infrastructure) environments, where multiple virtual desktops share the same base image and have a high degree of similarity. By deduplicating the data blocks across the virtual desktops, the storage space required for the VDI volume can be significantly reduced, which can mitigate the situation of the storage being 80% full.
NEW QUESTION # 151
A systems administrator needs to modify the replication factors of an automated application container from 3 to 5. Which of the following file types should the systems administrator modify on the master controller?
- A. .yaml
- B. . txt
- C. .conf
- D. .etcd
Answer: A
Explanation:
A .yaml file is a common file type for defining the configuration and deployment of application containers in a cloud environment. YAML stands for YAML Ain't Markup Language, and it is a human-readable data serialization language that uses indentation and keywords to represent the structure and values of the data1. A .yaml file can specify the properties of the container, such as the image, ports, environment variables, volumes, resources, and scaling rules. For example, to modify the replication factor of an automated application container from 3 to 5, the systems administrator can edit the .yaml file on the master controller and change the value of the replicas field under the spec section2. For example:
apiVersion: apps/v1 kind: Deployment metadata: name: my-app spec: replicas: 5 # change this value from 3 to 5 selector: matchLabels: app: my-app template: metadata: labels: app: my-app spec: containers: - name: my-app image: my-app-image ports: - containerPort: 80 A .txt file is a plain text file that can store any kind of text data, but it is not a standard format for defining container configurations. A .conf file is a configuration file that can store settings and parameters for various applications or services, but it is not commonly used for container deployments. A .etcd file is not a valid file type, but etcd is a distributed key-value store that provides a reliable way to store data across a cluster of machines3. Etcd is often used by Kubernetes, a popular platform for managing containerized applications, to store and synchronize the cluster state. However, etcd does not store the configuration files of the containers, but rather the runtime data of the cluster. Therefore, none of these options are correct.

NEW QUESTION # 155
A systems administrator is deploying a solution that includes multiple network I/O-intensive VMs. The solution design requires that vNICs of the VMs provide low-latency, near-native performance of a physical NIC and data protection between the VMs. Which of the following would BEST satisfy these requirements?
- A. GENEVE
- B. VLAN
- C. SR-IOV
- D. SDN
Answer: C
Explanation:
Explanation
SR-IOV (Single Root Input/Output Virtualization) is what would best satisfy the requirements of low-latency, near-native performance of a physical NIC and data protection between VMs for multiple network I/O-intensive VMs. SR-IOV is a technology that allows a physical NIC to be partitioned into multiple virtual NICs that can be assigned to different VMs. SR-IOV can provide the following benefits:
Low-latency: SR-IOV can reduce latency by bypassing the hypervisor and allowing direct communication between the VMs and the physical NIC, without any overhead or interference.
Near-native performance: SR-IOV can provide near-native performance by allowing the VMs to use the full capacity and functionality of the physical NIC, without any emulation or translation.
Data protection: SR-IOV can provide data protection by isolating and securing the network traffic between the VMs and the physical NIC, without any exposure or leakage.

Which of the following definitions of serverless computing BEST explains how it is different from using VMs?
- A. Serverless computing allows developers to focus on writing code and organizations to focus on business.
- B. Serverless computing is a scalable, highly available cloud service that uses SDN technologies.
- C. Serverless computing uses predictable billing and offers lower costs than VM compute services.
- D. Serverless computing is a cloud-hosting service that utilizes infrastructure that is fully managed by the CSP.
Answer: A
Explanation:
This is the best definition of serverless computing that explains how it is different from using VMs (Virtual Machines). Serverless computing is a cloud service model that provides customers with a platform to run applications or functions without having to manage or provision any underlying infrastructure or resources, such as servers, storage, network, OS, etc. Serverless computing is different from using VMs in the following ways:
Serverless computing allows developers to focus on writing code and organizations to focus on business, rather than spending time and effort on managing or scaling VMs or other infrastructure components.
Serverless computing is event-driven and pay-per-use, which means that applications or functions are executed only when triggered by a specific event or request, and customers are charged only for the resources consumed during the execution time.
Serverless computing is more scalable and flexible than using VMs, as it can automatically adjust the capacity and performance of applications or functions according to demand or workload, without requiring any manual intervention or configuration.
NEW QUESTION # 158
A systems administrator is concerned about having two virtual database servers on the same host. Which of the following should be configured?
- A. Regions
- B. Container
- C. Oversubscription
- D. Anti-affinity
Answer: D
Explanation:
The best way to prevent two virtual database servers from being on the same host is to configure anti-affinity. Anti-affinity is a feature that allows specifying which VMs or applications should not run on the same host or cluster. This can improve availability, performance, and security by avoiding resource contention, single point of failure, or interference between VMs or applications. The systems administrator should create an anti-affinity rule or policy for the two virtual database servers to ensure they are placed on different hosts. Reference: CompTIA Cloud+ Certification Exam Objectives, Domain 1.0 Configuration and Deployment, Objective 1.2 Given a scenario involving requirements for deploying an application in the cloud, select an appropriate solution design.
