A cloud administrator has finished setting up an application that will use RDP to connect. During testing, users experience a connection timeout error.
Which of the following will MOST likely solve the issue?
- A. Checking user passwords
- B. Opening TCP port 3389
- C. Configuring QoS rules
- D. Enforcing TLS authentication
Answer: B
Explanation:
TCP port 3389 is the default port used by Remote Desktop Protocol (RDP) to connect to a remote system or application over a network. Opening TCP port 3389 on the firewall or network device will most likely solve the issue of users experiencing a connection timeout error when trying to use RDP to connect to an application, as it will allow RDP traffic to pass through. If TCP port 3389 is closed or blocked, RDP traffic will be denied or dropped, resulting in a connection timeout error.

NEW QUESTION # 57
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 # 58
A company is preparing a hypervisor environment to implement a database cluster. One of the requirements is to share the disks between the nodes of the cluster to access the same LUN. Which of the following protocols Should the company use? (Select TWO)
- A. CIFS
- B. Raid 10
- C. Nfs
- D. Iscsi
- E. FTP
- F. fc
Answer: D,F
Explanation:
Explanation
The correct answer is C and F. iSCSI and FC.
iSCSI and FC are protocols that the company can use to share the disks between the nodes of the cluster to access the same LUN. A LUN, or logical unit number, is a unique identifier for a block of storage space that can be accessed by a host system or a cluster of systems. iSCSI and FC are both block-level protocols that allow transferring data between the storage device and the host system or cluster over a network.
iSCSI stands for Internet Small Computer System Interface, which is a protocol that uses TCP/IP to send SCSI commands over an Ethernet network. iSCSI can provide a low-cost and flexible solution for sharing disks between the nodes of the cluster, as it does not require any special hardware or cables, and can use existing network infrastructure. iSCSI can also support encryption and authentication for security purposes .
FC stands for Fibre Channel, which is a protocol that uses optical fiber cables to send SCSI commands over a dedicated network. FC can provide a high-performance and reliable solution for sharing disks between the nodes of the cluster, as it offers high bandwidth, low latency, and error correction. FC can also support zoning and masking for security purposes .
CIFS, or Common Internet File System, is a file-level protocol that allows sharing files and folders over a network. CIFS does not support sharing disks or accessing LUNs at the block level.
FTP, or File Transfer Protocol, is a protocol that allows transferring files between two systems over a network.
FTP does not support sharing disks or accessing LUNs at the block level.
NFS, or Network File System, is a file-level protocol that allows sharing files and folders over a network. NFS does not support sharing disks or accessing LUNs at the block level.
RAID 10, or Redundant Array of Independent Disks 10, is a storage configuration that combines mirroring and striping to provide high performance and fault tolerance. RAID 10 is not a protocol that allows sharing disks or accessing LUNs over a network.

- A. SDN
- B. VLAN
- C. DoH
- D. IPAM
Answer: D
Explanation:
Explanation
The best solution to simplify management of a more complex DNS and DHCP environment for a company that has grown over the last couple of years is IPAM (IP address management). IPAM is a tool or service that allows centralized management and automation of DNS and DHCP functions, such as IP address allocation, reservation, release, or renewal, as well as domain name registration or resolution. IPAM can also provide monitoring, auditing, reporting, and security features for DNS and DHCP resources.

NEW QUESTION # 61
A cloud administrator is reviewing the current private cloud and public laaS environment, and is building an optimization plan. Portability is of great concern for the administrator so resources can be easily moved from one environment to another.
Which of the following should the administrator implement?
- A. CDN
- B. Containers
- C. Deduplication
- D. Serverless
Answer: B
Explanation:
Containers are packages of software that contain all of the necessary elements to run in any environment.
Containers virtualize the operating system and run anywhere, from a private data center to the public cloud or even on a developer's personal laptop. Containers provide an isolated environment for running applications, sharing the host OS kernel but isolating processes, file systems, and network resources. Containers package applications and their dependencies together, ensuring they run consistently across different environments, from development to production. Containers are lightweight, resource-efficient, fast, and immutable, making them ideal for portability and scalability. By using containers, a cloud administrator can easily move resources from one environment to another without changing the code or configuration of the applications. References:

NEW QUESTION # 62
A company has decided to scale its e-commerce application from its corporate datacenter to a commercial cloud provider to meet an anticipated increase in demand during an upcoming holiday.
The majority of the application load takes place on the application server under normal conditions. For this reason, the company decides to deploy additional application servers into a commercial cloud provider using the on-premises orchestration engine that installs and configures common software and network configurations.
The remote computing environment is connected to the on-premises datacenter via a site-to-site IPSec tunnel.
The external DNS provider has been configured to use weighted round-robin routing to load balance connections from the Internet.
During testing, the company discovers that only 20% of connections completed successfully.
INSTRUCTIONS
Review the network architecture and supporting documents and fulfill these requirements:
Part 1:
Analyze the configuration of the following components: DNS, Firewall 1, Firewall 2, Router 1, Router 2, VPN and Orchestrator Server.
Identify the problematic device(s).
Part 2:
Identify the correct options to provide adequate configuration for hybrid cloud architecture.
If at any time you would like to bring back the initial state of the simulation, please click the Reset All button.
Part 1:
Cloud Hybrid Network Diagram
Part 2:
Only select a maximum of TWO options from the multiple choice question
Answer:
Explanation:
See explanation below.
Explanation:
Part 1: Router 2
The problematic device is Router 2, which has an incorrect configuration for the IPSec tunnel. The IPSec tunnel is a secure connection between the on-premises datacenter and the cloud provider, which allows the traffic to flow between the two networks. The IPSec tunnel requires both endpoints to have matching parameters, such as the IP addresses, the pre-shared key (PSK), the encryption and authentication algorithms, and the security associations (SAs) .
According to the network diagram and the configuration files, Router 2 has a different PSK and a different address space than Router 1. Router 2 has a PSK of "1234567890", while Router 1 has a PSK of
"0987654321". Router 2 has an address space of 10.0.0.0/8, while Router 1 has an address space of
192.168.0.0/16. These mismatches prevent the IPSec tunnel from establishing and encrypting the traffic between the two networks.
The other devices do not have any obvious errors in their configuration. The DNS provider has two CNAME records that point to the application servers in the cloud provider, with different weights to balance the load.
The firewall rules allow the traffic from and to the application servers on port 80 and port 443, as well as the traffic from and to the VPN server on port 500 and port 4500. The orchestration server has a script that installs and configures the application servers in the cloud provider, using the DHCP server to assign IP addresses.
Part 2:
The correct options to provide adequate configuration for hybrid cloud architecture are:
* Update the PSK in Router 2.
* Change the address space on Router 2.
These options will fix the IPSec tunnel configuration and allow the traffic to flow between the on-premises datacenter and the cloud provider. The PSK should match the one on Router 1, which is "0987654321". The address space should also match the one on Router 1, which is 192.168.0.0/16.
B. Update the PSK (Pre-shared key in Router2)
E. Change the Address Space on Router2

NEW QUESTION # 76
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 3, 4, and 5.
- B. Remove rules 2, 3, and 4.
- C. Remove rules 1, 3, and 4.
- D. Remove rules 1, 2, and 5.
Answer: D
Explanation:
Explanation
To ensure the web servers in the public subnet allow only secure communications and remediate any possible issue, the analyst should remove rules 1, 2, and 5 from the stateful configuration. These rules are allowing insecure or unnecessary traffic to or from the web servers, which may pose security risks or performance issues. The rules are:
Rule 1: This rule allows inbound traffic on port 80 (HTTP) from any source to any destination. HTTP is an unencrypted and insecure protocol that can expose web traffic to interception, modification, or spoofing. The analyst should remove this rule and use HTTPS (port 443) instead, which encrypts and secures web traffic.
Rule 2: This rule allows outbound traffic on port 25 (SMTP) from any source to any destination. SMTP is a protocol that is used to send email messages. The web servers in the public subnet do not need to send email messages, as this is not their function. The analyst should remove this rule and block outbound SMTP traffic, which may prevent spamming or phishing attacks from compromised web servers.
Rule 5: This rule allows inbound traffic on port 22 (SSH) from any source to any destination. SSH is a protocol that allows remote access and management of systems or devices using a command-line interface. The web servers in the public subnet do not need to allow SSH access from any source, as this may expose them to unauthorized or malicious access. The analyst should remove this rule and restrict SSH access to specific sources, such as the administrator's workstation or a bastion host.
