- B. Use the database import/export method and copy the exported file.
- C. Utilize a third-party tool to back up and restore the data to the new database.
- D. Create a replica database, synchronize the data, and switch to the new instance.
Answer: D
Explanation:
The best option to perform the database migration is to create a replica database, synchronize the data, and switch to the new instance. This option can help meet the restricted SLA and avoid offline time for the database. Creating a replica database can help copy the data from the source to the destination without interrupting the database operations. Synchronizing the data can help ensure that the replica database is updated with any changes that occur in the source database during the migration process. Switching to the new instance can help complete the migration and activate the new database in the cloud. This option can also help avoid the network bandwidth limitation and the large size of the dat a.

- A. Hub and spoke
- B. VPN connections
- C. VPC peering
- D. MPLS connections
Answer: A
Explanation:
The best way to connect all the VPCs for the company that is planning its cloud architecture and wants to use a VPC for each of its three products per environment in two regions, totaling 18 VPCs, is to use a hub and spoke model. A hub and spoke model is a networking model that uses a central hub VPC that connects to multiple spoke VPCs that host the products or workloads. The hub VPC can provide common services and security policies for the spoke VPCs, such as network virtual appliances, DNS servers, firewalls, or VPN gateways. The spoke VPCs can communicate with each other through the hub VPC, using private IP addresses or peering connections. A hub and spoke model can simplify the management and scalability of the network, as well as reduce the costs and complexity of peering multiple VPCs directly.

NEW QUESTION # 92
A cloud security engineer needs to design an IDS/IPS solution for a web application in a single virtual private network. The engineer is considering implementing IPS protection for traffic coming from the internet. Which of the following should the engineer consider to meet this requirement?
- A. Implementing IDS/IPS agents on each instance running in that virtual private network
- B. Implementing load balancing using SSI- in front of web applications
- C. Configuring a web proxy server
- D. Implementing dynamic routing
Answer: A
Explanation:
An Intrusion Detection System (IDS) is a software or hardware system that monitors network traffic for malicious activity and alerts the administrator of any potential threats. An Intrusion Prevention System (IPS) is a software or hardware system that not only detects but also blocks or mitigates the malicious activity. Both IDS and IPS are essential for securing a web application in a cloud environment1.
A web proxy server is a server that acts as an intermediary between the client and the web server. It can provide caching, filtering, and authentication services, but it does not offer IDS/IPS functionality. Therefore, option A is incorrect.
Load balancing using SSI (Server Side Includes) is a technique that distributes the workload among multiple web servers by inserting dynamic content into web pages. It can improve the performance and availability of a web application, but it does not provide IDS/IPS protection. Therefore, option B is incorrect.
Implementing IDS/IPS agents on each instance running in that virtual private network is a valid solution for providing IPS protection for traffic coming from the internet. The agents can monitor and inspect the network traffic on each instance and block or report any suspicious activity to a central management console. This can prevent attacks from reaching the web application or spreading to other instances in the same network. Therefore, option C is correct.
Implementing dynamic routing is a technique that allows routers to select the best path for forwarding packets based on network conditions. It can enhance the reliability and efficiency of a network, but it does not offer IDS/IPS functionality. Therefore, option D is incorrect.
NEW QUESTION # 93
A VDI administrator is enhancing the existing environment with a feature to allow users to connect devices to virtual workstations. Which of the following types of devices are most likely to be allowed in the upgrade? (Select two).
- A. PCI devices
- B. SATA devices
- C. PCIe devices
- D. USB devices
- E. Printers
- F. Display monitors
Answer: D,E
Explanation:
B) USB devices and F. Printers are most likely to be allowed in the upgrade. USB devices are common peripherals that users may want to connect to their virtual workstations, such as flash drives, keyboards, mice, webcams, etc. Printers are also useful devices that users may need to print documents from their virtual desktops. VDI software can support USB redirection and printer redirection to enable these devices to work with virtual workstations12.
Display monitors, SATA devices, PCIe devices, and PCI devices are less likely to be allowed in the upgrade, as they are either part of the physical hardware of the end device or the server, or they require direct access to the host system. VDI software typically does not support these types of devices, as they are not compatible with the virtualization layer or the remote display protocol34.
NEW QUESTION # 94
A system administrator has provisioned a new web server. Which of the following, in combination, form the best practice to secure the server's OS? (Choose three.)
- A. Forward port 80 traffic to port 443.
- B. Enable SSH key access only.
- C. Restrict access on port 22 to the IP address of the administrator's workstation.
- D. Disable TLS 1.0/1.1 and SSL.
- E. Install TLS certificates on the server.
- F. Provision the server in a separate VPC.
- G. Disable the superuser/administrator account.
- H. Disable password authentication.
Answer: B,E,H
Explanation:
These are the best practices to secure the OS of a new web server that has been provisioned in a cloud environment:
Install TLS certificates on the server: TLS (Transport Layer Security) certificates are digital documents that contain information such as identity, public key, expiration date, etc., that can be used to prove one's identity and establish secure communication over a network. Installing TLS certificates on the web server can encrypt and secure web traffic between the server and the clients, as well as prevent spoofing or impersonation attacks.
Disable password authentication: Password authentication is a method of verifying and authenticating users or devices based on passwords or other credentials. Password authentication can be insecure or vulnerable to attacks such as brute force, dictionary, phishing, etc., especially if passwords are weak, reused, or compromised. Disabling password authentication can enhance security by preventing unauthorized or malicious access to the web server using passwords.
Enable SSH key access only: SSH key access is a method of verifying and authenticating users or devices based on digital keys issued by a trusted authority. SSH key access can provide more security and convenience than password authentication, as it does not require users or devices to remember or enter passwords every time they access the web server. Enabling SSH key access only can ensure that only authorized or trusted users or devices can access the web server using keys.
NEW QUESTION # 95
A systems administrator wants to have near-real-time information on the volume of data being exchanged between an application server and its clients on the Internet.
Which of the following should the systems administrator implement to achieve this objective?
- A. Network flows
- B. A stateful firewall
- C. DNSSEC
- D. DLP
Answer: A
Explanation:
Network flows are records of network traffic that capture information such as source and destination IP addresses, ports, protocols, timestamps, and byte and packet counts. Network flows can provide near-real-time information on the volume of data being exchanged between a system and its clients on the Internet, as they can measure and monitor the amount and rate of network traffic for each connection or session. Network flows can also help analyze network performance, troubleshoot network issues, and detect network anomalies or security incidents. A systems administrator should implement network flows to achieve the objective of having near-real-time information on the volume of data being exchanged between an application server and its clients on the Internet. Reference: CompTIA Cloud+ Certification Exam Objectives, page 16, section 3.2

NEW QUESTION # 97
An application deployment team has observed delays in deployments and has asked the cloud administrator to evaluate the issue. Below is the result of a latency test that was conducted by the cloud administrator from offices located in the following regions:
* Asia-Pacific (APAC)
* Europe, the Middle East, and Africa (EMEA)
* Americas
Tests were conducted from each location, and the results are shown below:
Which of the following locations needs to be investigated further?
- A. * Connectivity from APAC to all regions
* Connectivity from Americas to all regions - B. * Connectivity from APAC to APAC regions
* Connectivity from APAC to EMEA and US - North - C. * Connectivity from EMEA to all regions
* Connectivity from APAC to APAC and EMEA regions - D. * Connectivity from APAC to EMEA and Americas regions
* Connectivity from EMEA to all regions
Answer: D
Explanation:
The latency test results show that the connectivity from APAC to EMEA and Americas regions has the highest latency values, ranging from 162 ms to 380 ms. This indicates that there is a significant delay in the network communication between these regions, which could affect the performance and availability of the cloud services. The connectivity from EMEA to all regions also has high latency values, ranging from 60 ms to 328 ms, which could also cause issues for the application deployment team. Therefore, these locations need to be investigated further to identify and resolve the root cause of the network latency.
Some possible causes of network latency are :
Congestion: The network bandwidth may be insufficient to handle the volume of traffic, resulting in packet loss, retransmission, and queuing delays.
Distance: The physical distance between the source and destination nodes may increase the propagation delay, which is the time it takes for a signal to travel through a medium.
Routing: The network topology and configuration may affect the number and quality of hops that a packet takes to reach its destination, resulting in transmission and processing delays.
Hardware: The performance and capacity of the network devices, such as routers, switches, firewalls, and servers, may affect the speed and efficiency of data processing and delivery.
Some possible solutions to reduce network latency are :
Scaling: The network resources can be increased or optimized to handle the traffic demand, such as adding more bandwidth, load balancers, or caching servers.
Location: The network nodes can be placed closer to each other or to the end users, such as using edge computing, content delivery networks (CDNs), or regional cloud data centers.
Routing: The network routes can be improved or optimized to reduce the number and distance of hops, such as using direct peering, dedicated circuits, or software-defined networking (SDN).
Hardware: The network devices can be upgraded or replaced with faster and more reliable ones, such as using solid-state drives (SSDs), fiber-optic cables, or 5G technology.
