NEW QUESTION # 29
A systems administrator in a large enterprise needs to alter the configuration of one of the finance department's database servers.
Which of the following should the administrator perform FIRST?
- A. Change management
- B. Capacity planning
- C. Patching
- D. Backups
Answer: A
Explanation:
Explanation
The SA would do the other three regardless of the need to alter configurations. In this situation, the SA would have to present the change to the CCB in order to do the alteration.
There is no clarification on whether the change management process has been gone through. Any changes, regardless of how small or big, must go through the change management process. This allows proposals to be heard by end-users, management, and possibly stockholders. From there, it will be reviewed and either approved or denied, with reasons specified. From there, the administrator(s) can do whatever processes are necessary.
Change management is a process or procedure that defines the steps, roles, and responsibilities for implementing, documenting, and communicating any changes or updates to a system or service. Change management can help ensure that any changes or updates are done in a controlled and consistent manner, minimizing any risks or impacts to the system or service. Performing change management is the first thing that a systems administrator should do before altering the configuration of one of the finance department's database servers, as it can ensure that the change request is approved, authorized, tested, and verified before applying it to the database server.

NEW QUESTION # 31
An organization is using multiple SaaS-based business applications, and the systems administrator is unable to monitor and control the use of these subscriptions. The administrator needs to implement a solution that will help the organization apply security policies and monitor each individual SaaS subscription. Which of the following should be deployed to achieve these requirements?
- A. HIDS
- B. IPS
- C. CASB
- D. DLP
Answer: C
Explanation:
CASB (Cloud Access Security Broker) is what should be deployed to monitor and control the use of multiple SaaS-based business applications in a cloud environment. SaaS (Software as a Service) is a cloud service model that provides customers with access to software applications hosted on remote servers over a network or internet connection. SaaS can provide customers with convenience, flexibility, and scalability, but it may also introduce security risks such as data breaches, leaks, losses, etc., especially if customers have multiple SaaS subscriptions from different providers. CASB is a tool or service that acts as an intermediary between customers and SaaS providers. CASB can help to monitor and control the use of multiple SaaS subscriptions by providing features such as:
Visibility: CASB can provide visibility into what SaaS applications are being used, by whom, when, where, how, etc., as well as identify any unauthorized or suspicious activities.
Compliance: CASB can provide compliance with various laws, regulations, standards, policies, etc., that apply to SaaS applications and data, such as GDPR, HIPAA, PCI DSS, etc., as well as enforce them using rules or actions.
Security: CASB can provide security for SaaS applications and data by detecting and preventing any threats or attacks, such as malware, phishing, ransomware, etc., as well as protecting them using encryption, authentication, authorization, etc.
NEW QUESTION # 32
A company is currently running a website on site. However, because of a business requirement to reduce current RTO from 12 hours to one hour, and the RPO from one day to eight hours, the company is considering operating in a hybrid environment. The website uses mostly static files and a small relational database. Which of the following should the cloud architect implement to achieve the objective at the LOWEST cost possible?
- A. Implement a website replica in the cloud with auto-scaling using the smallest possible footprint. Use DNS to shift the load from on premises to the cloud.
- B. Implement a CDN that caches all requests with a higher TTL and deploy the laaS instances manually in case of disaster. Upload the backup on demand to the cloud to restore on the new instances.
- C. Implement a load-balanced environment in the cloud that is equivalent to the current on-premises setup and use DNS to shift the load from on premises to cloud.
- D. Implement backups to cloud storage and infrastructure as code to provision the environment automatically when the on-premises site is down. Restore the data from the backups.
Answer: A
Explanation:
This is the best solution to achieve the objective of reducing current RTO (Recovery Time Objective) from 12 hours to one hour, and RPO (Recovery Point Objective) from one day to eight hours, at the lowest cost possible, for a website that uses mostly static files and a small relational database. RTO is a metric that measures how quickly a system or service can be restored after a disruption or disaster. RPO is a metric that measures how much data can be lost or how far back in time a recovery point can be without causing significant impact or damage. To reduce RTO and RPO, the administrator should implement a website replica in the cloud with auto-scaling using the smallest possible footprint. A website replica is a copy or backup of a website that can be used for recovery or failover purposes. Auto-scaling is a feature that allows cloud resources or systems to adjust their capacity and performance according to demand or workload. Using auto-scaling with the smallest possible footprint can minimize costs by using only the necessary resources and scaling up or down as needed. The administrator should also use DNS (Domain Name System) to shift the load from on premises to the cloud. DNS is a service that translates domain names into IP addresses and vice versa. Using DNS, the administrator can redirect traffic from the on-premises website to the cloud replica in case of a disruption or disaster, and vice versa when recovery is complete.
NEW QUESTION # 33
When designing a three-node. load-balanced application, a systems administrator must ensure each node runs on a different physical server for HA purposes. Which of the following does the systems administrator need to configure?
- A. Live migration
- B. Round-robin methods
- C. Anti-affinity rule
- D. Priority queues
Answer: C
Explanation:
Explanation
The correct answer is C. Anti-affinity rule.
An anti-affinity rule is a configuration option that prevents two or more virtual machines (VMs) from running on the same physical host. This can improve the availability and fault tolerance of the VMs, as it reduces the risk of losing multiple VMs due to a single host failure. An anti-affinity rule can also improve the performance and load balancing of the VMs, as it distributes the workload across different hosts and avoids resource contention .
A round-robin method is a load balancing algorithm that distributes incoming requests to a pool of servers in a circular order. A round-robin method does not consider the availability, capacity, or location of the servers, and may assign requests to servers that are overloaded, offline, or far away. A round-robin method does not ensure that each node runs on a different physical server.
A live migration is a process that allows moving a running VM from one physical host to another without interrupting its operation. A live migration can improve the availability and performance of the VMs, as it enables dynamic load balancing, maintenance, and disaster recovery. However, a live migration does not prevent two or more VMs from running on the same physical host in the first place.
A priority queue is a data structure that stores elements based on their priority values. A priority queue allows inserting and removing elements in order of their priority, such that the element with the highest priority is always at the front of the queue. A priority queue can be used to implement scheduling algorithms for processes or tasks, but it does not affect where they run on physical servers.

NEW QUESTION # 40
A cloud engineer needs to perform a database migration_ The database has a restricted SLA and cannot be offline for more than ten minutes per month The database stores 800GB of data, and the network bandwidth to the CSP is 100MBps. Which of the following is the BEST option to perform the migration?
- A. Create a replica database, synchronize the data, and switch to the new instance.
- B. Utilize a third-patty tool to back up and restore the data to the new database
- C. use the database import/export method and copy the exported file.
- D. Copy the database to an external device and ship the device to the CSP
Answer: A
Explanation:
Explanation
The correct answer is B. Create a replica database, synchronize the data, and switch to the new instance.
This option is the best option to perform the migration because it can minimize the downtime and data loss during the migration process. A replica database is a copy of the source database that is kept in sync with the changes made to the original database. By creating a replica database in the cloud, the cloud engineer can transfer the data incrementally and asynchronously, without affecting the availability and performance of the source database. When the replica database is fully synchronized with the source database, the cloud engineer can switch to the new instance by updating the connection settings and redirecting the traffic. This can reduce the downtime to a few minutes or seconds, depending on the complexity of the switch.
Some of the tools and services that can help create a replica database and synchronize the data are AWS Database Migration Service (AWS DMS) 1, Azure Database Migration Service 2, and Striim 3. These tools and services can support various source and target databases, such as Oracle, MySQL, PostgreSQL, SQL Server, MongoDB, etc. They can also provide features such as schema conversion, data validation, monitoring, and security.
The other options are not the best options to perform the migration because they can cause more downtime and data loss than the replica database option.
Copying the database to an external device and shipping the device to the CSP is a slow and risky option that can take days or weeks to complete. It also exposes the data to physical damage or theft during transit. Moreover, this option does not account for the changes made to the source database after copying it to the device, which can result in data inconsistency and loss.
Utilizing a third-party tool to back up and restore the data to the new database is a faster option than shipping a device, but it still requires a significant amount of downtime and bandwidth. The source database has to be offline or in read-only mode during the backup process, which can take hours or days depending on the size of the data and the network speed. The restore process also requires downtime and bandwidth, as well as compatibility checks and configuration adjustments. Additionally, this option does not account for the changes made to the source database after backing it up, which can result in data inconsistency and loss.
Using the database import/export method and copying the exported file is a similar option to using a third-party tool, but it relies on native database features rather than external tools. The import/export method involves exporting the data from the source database into a file format that can be imported into the target database. The file has to be copied over to the target database and then imported into it. This option also requires downtime and bandwidth during both export and import processes, as well as compatibility checks and configuration adjustments. Furthermore, this option does not account for the changes made to the source database after exporting it, which can result in data inconsistency and loss.

NEW QUESTION # 43
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. Configuring a web proxy server
- B. Implementing IDS/IPS agents on each instance running in that virtual private network
- C. Implementing dynamic routing
- D. Implementing load balancing using SSI- in front of web applications
Answer: B
Explanation:
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.
