Nutanix NCP-DB Test Dumps

A.   Update the software profile to include the ASMLIB driver.

Answer DescriptionExplanation:
In the context of Nutanix Database Automation (NCP-DB), when provisioning a new Oracle SIHA DB & VM, if only ASMFD is available in the ASM Driver drop-down, it indicates that ASMLIB is not included in the current software profile. To provision the requested SIHA DB and DB VM with ASMLIB, it’s essential to update the software profile to include the ASMLIB driver. This action will enable ASMLIB as an option in the ASM Driver drop-down during the provisioning workflow.

A.   From the Database Summary page for the DBA database, use the Scale option to grow the storage accordingly.

Answer DescriptionExplanation: The administrator can remediate the issue of critical storage alerts by scaling up the storage directly from the Database Summary page for that specific DBA database. This action allows for an increase in storage capacity to alleviate space constraints and prevent future critical alerts related to storage space1. The other options are not correct, as they either involve scaling the entire database group, which may not be necessary or desired, or require additional steps outside of NDB, which may not be feasible or efficient.

B.   MySQL

Answer DescriptionExplanation:
The error message in the exhibit indicates that the operation failed during the “Create and Register Database Server VMs” step because “Provisioning of all the observers simultaneously took more than two hours.” This type of error is associated with MySQL, as it involves observers which are a part of MySQL Group Replication, used for ensuring high availability1. The other options are not related to the error message, as they do not use observers or Group Replication for clustering.

C.   The administrator is logged in with the Database Admin account.

Answer DescriptionExplanation:
Based on the exhibit, the administrator is logged in with the Database Admin account (bsmith@ntnxlab.local), which does not have the permission to create local users on NDB. Only the Super Admin account (bsmith) has this permission, as indicated by the User type column. Therefore, the administrator needs to log out and log in again with the Super Admin account to add a new database admin as a local user to NDB.

C.   3205 and 3260

Answer DescriptionExplanation:
According to the Nutanix Database Automation (NCP-DB) course, the ports 3205 and 3260 are required for iSCSI connections between the NDB server and the Controller VMs1. Port 3205 is used for the NDB iSCSI initiator service, which initiates the iSCSI sessions and sends SCSI commands to the Controller VMs1. Port 3260 is used for the iSCSI target service, which listens for incoming iSCSI requests and provides access to the storage devices on the Controller VMs1. The other options are not related to iSCSI connections. Port 22 is used for SSH, port 9440 is used for Prism Central, port 80 is used for HTTP, port 443 is used for HTTPS, port 5985 is used for WinRM HTTP, and port 5986 is used for WinRM HTTPS2.

B.   VLAN must be static.


C.   Both clusters must be registered in NDB.

Answer DescriptionExplanation:
A stretched VLAN is a virtual network that spans across multiple Nutanix clusters and allows the communication between VMs on different clusters using the same subnet. A stretched VLAN can be used to provide high availability and load balancing for NDB components, such as HAProxy VMs, that require a virtual IP address (VIP) to be accessible from any cluster. To add a stretched VLAN across two clusters in NDB, the administrator needs to meet two prerequisites: the VLAN must be static and both clusters must be registered in NDB. A static VLAN is a VLAN that is manually created and configured by the administrator, as opposed to an IPAM VLAN that is automatically created and managed by NDB. A static VLAN can be added to a stretched VLAN in NDB, while an IPAM VLAN cannot. Both clusters must be registered in NDB before adding a stretched VLAN, as NDB needs to have the information and access to the clusters and their networks. The administrator can register the clusters in NDB using the Prism Element details, agent network configuration, and storage container information. The other option, Nutanix Cluster Management, is not a prerequisite for adding a stretched VLAN in NDB. Nutanix Cluster Management is a feature that allows the administrator to manage multiple Nutanix clusters from a single NDB UI, such as creating or deleting clusters, adding or removing nodes, or performing cluster operations. Nutanix Cluster Management is not required for adding a stretched VLAN, as the VLANs are created and configured in Prism Element, not in NDB.

A.   TLS


B.   SSL

Answer DescriptionExplanation:
NDB supports SMTP server configuration for sending email notifications and alerts. SMTP server configuration requires specifying the SMTP server address, port, username, password, and encryption method. The encryption method determines how the email messages are secured during transmission. NDB supports two encryption methods for SMTP server configuration: TLS and SSL.
TLS (Transport Layer Security) is a protocol that encrypts and authenticates data between the email client and the SMTP server. TLS can operate in two modes: explicit and implicit. In explicit mode, the email client and the SMTP server negotiate the encryption method and parameters after establishing a plain text connection. This mode typically uses port 587. In implicit mode, the email client and the SMTP server assume that the connection is encrypted from the start, without any negotiation. This mode typically uses port 465.
SSL (Secure Sockets Layer) is a predecessor of TLS that also encrypts and authenticates data between the email client and the SMTP server. SSL operates in implicit mode only, and uses port 465 by default. SSL is less secure than TLS, but it is still widely used and supported by many email providers.
S/MIME (Secure/Multipurpose Internet Mail Extensions) is a standard that encrypts and signs email messages at the application layer, rather than the transport layer. S/MIME requires the use of digital certificates and public key cryptography to ensure the confidentiality and integrity of email messages. S/MIME is not a valid encryption method for SMTP server configuration, as it does not affect the connection between the email client and the SMTP server.
IPsec (Internet Protocol Security) is a suite of protocols that secures IP packets at the network layer, rather than the application or transport layer. IPsec can encrypt and authenticate data between any two IP endpoints, such as routers, firewalls, or hosts. IPsec is not a valid encryption method for SMTP server configuration, as it does not apply to the specific protocol or port used by SMTP.
