NEW QUESTION # 120
A cloud engineer is deploying a server in a cloud platform. The engineer reviews a security scan report. Which of the following recommended services should be disabled? (Select TWO).
Answer: A,F
Explanation:
Explanation
Telnet and FTP are two services that should be disabled on a cloud server because they are insecure and vulnerable to attacks. Telnet and FTP use plain text to transmit data over the network, which means that anyone who can intercept the traffic can read or modify the data, including usernames, passwords, commands, files, etc. This can lead to data breaches, unauthorized access, or malicious actions on the server1.
Instead of Telnet and FTP, more secure alternatives should be used, such as SSH (Secure Shell) and SFTP (Secure File Transfer Protocol). SSH and SFTP use encryption to protect the data in transit and provide authentication and integrity checks for the communication. SSH and SFTP can prevent eavesdropping, tampering, or spoofing of the data and ensure the confidentiality and privacy of the server2.
The other options are not services that should be disabled on a cloud server:
Option C: Remote login. Remote login is a service that allows users to access a remote server from another location using a network connection. Remote login can be useful for managing, configuring, or troubleshooting a cloud server without having to physically access it. Remote login can be secured by using encryption, authentication, authorization, and logging mechanisms3.
Option D: DNS (Domain Name System). DNS is a service that translates human-friendly domain names into IP addresses that can be used to communicate over the Internet. DNS is essential for resolving the names of the cloud resources and services that are hosted on the cloud platform. DNS can be secured by using DNSSEC (DNS Security Extensions), which add digital signatures to DNS records to verify their authenticity and integrity.
Option E: DHCP (Dynamic Host Configuration Protocol). DHCP is a service that assigns IP addresses and other network configuration parameters to devices on a network. DHCP can simplify the management of IP addresses and avoid conflicts or errors in the network. DHCP can be secured by using DHCP snooping, which filters out unauthorized DHCP messages and prevents rogue DHCP servers from assigning IP addresses.
Option F: LDAP (Lightweight Directory Access Protocol). LDAP is a service that stores and organizes information about users, devices, and resources on a network. LDAP can provide identity management and access control for the cloud environment. LDAP can be secured by using LDAPS (LDAP over SSL/TLS), which encrypts the LDAP traffic and provides authentication and integrity checks.
NEW QUESTION # 121
Which of the following definitions of serverless computing BEST explains how it is different from using VMs?
Answer: C
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 # 122
An organization is currently deploying a private cloud model. All devices should receive the time from the local environment with the least administrative effort. Which of the following ports needs to be opened to fulfill this requirement?
Answer: D
Explanation:
Reference:
https://www.sciencedirect.com/topics/computer-science/network-time-protocol#:~:text=NTP%20is%20a%20bui Port 123 is what needs to be opened to ensure all devices receive the time from the local environment with the least administrative effort in a private cloud model. Port 123 is the port used by NTP (Network Time Protocol), which is a protocol that synchronizes the clocks of network devices and systems. NTP can help to ensure accurate and consistent time across different devices and systems in a cloud environment, which can facilitate coordination, communication, logging, auditing, etc.
NEW QUESTION # 123
Which of the following is used in Object-Based Storage to reference the servers that provide services to store, retrieve, and manage data in the Object-Based Storage system?
Answer: B
NEW QUESTION # 124
A systems administrator has verified that a physical switchport that is connected to a virtualization host is using all available bandwidth. Which of the following would best address this issue?
Answer: D
Explanation:
Link aggregation is a technique that combines multiple physical links into a logical link that provides higher bandwidth and redundancy. Link aggregation can help address the issue of a physical switchport that is connected to a virtualization host using all available bandwidth by increasing the capacity and availability of the connection. Link aggregation can also balance the traffic load across the links and improve the fault tolerance of the network. Link aggregation can be implemented using protocols such as LACP (Link Aggregation Control Protocol) or static configuration.
