NEW QUESTION # 212
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 3.4. and 5.
- C. Remove rules I, 3, and 4.
- D. Remove rules 2.3. and 4.
Answer: C
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 # 213

NEW QUESTION # 215
A cloud administrator is setting up a DR site on a different zone of the same CSP. The application servers are replicated using the VM replication, and the database replication is set up using log shipping. Upon testing the DR site, the application servers are unable to access the database servers. The administrator has verified the systems are running and are accessible from the CSP portal.
Which of the following should the administrator do to fix this issue?
- A. Update the connection string
- B. Change the database application IP
- C. Create a database cluster between the primary site and the DR site
- D. Edit the DNS record at the DR site for the application servers
Answer: A
Explanation:
Explanation
A connection string is a parameter that specifies how to connect to a database server or instance. A connection string typically includes information such as the server name, database name, user name, password, and other options. Updating the connection string is the best way to fix the issue of application servers being unable to access the database servers after setting up a DR site on a different zone of the same CSP and replicating the application and database servers using VM replication and log shipping. Updating the connection string can ensure that the application servers can connect to the correct database server or instance in the DR site, as the server name or IP address may have changed after the replication.

NEW QUESTION # 218
A security analyst is investigating incidents in which attackers are able to access sensitive data from a corporate application's database. The attacks occur periodically and usually after the release of a new application's version. The following log confirms the compromise:
<date> USER: WebApp access-key accepted
<date> WebApp user assumed DBA role
<date> GetData API call executed
The following actions are made after every incident occurrence:
* Validation of firewall rules
* Scripted rebuild of the database and web instances
* Application deployment from a cloud code repository
Which of the following actions will MOST likely prevent future compromises?
- A. Migrating the database to be on premises
- B. Implementing a new database service account
- C. Forbidding the use of API calls to retrieve data
- D. Rotating the account credentials
Answer: D
Explanation:
One possible cause for the incidents in which attackers are able to access sensitive data from a corporate application's database is that the account credentials used by the web application to access the database are compromised or leaked. The log confirms that the attackers are using the WebApp user account to assume the DBA role and execute the GetData API call, which could allow them to retrieve any data from the database. The account credentials could be compromised or leaked due to various reasons, such as weak passwords, phishing attacks, code injection, or insecure storage or transmission. Therefore, one action that will most likely prevent future compromises is to rotate the account credentials, which means changing them periodically or after every incident occurrence. Rotating the account credentials can reduce the risk of unauthorized access by invalidating the old or stolen credentials and enforcing strong and unique passwords for each account.
NEW QUESTION # 219
