Pass the F5 BIG-IP DNS 302 Questions and answers with CertsForce

Explanation

Generating a new Private Key and Certificate Signing Request (CSR) when renewing a digital certificate is important to mitigate against potential SSL vulnerabilities. By creating a new Private Key and CSR, the organization can ensure that the encryption keys are secure and not compromised, reducing the risk of unauthorized access or data breaches.

Adding the GTM System to the Synchronization Group

Disconnect the Disconnected TMM Switch ports

Adding the GTM System to the Synchronization Group

Clear the Synchronization Check Box

Click delete Bottom

Physically disconnecting the TMM switch ports from the production network ensures that the F5 GTM system is isolated from the synchronization group, allowing updates to be performed without affecting the entire group. This step prevents any changes made to the individual system from being synchronized with the rest of the group.

Clearing the synchronization checkbox and clicking the update button will remove the F5 GTM system from the synchronization process, ensuring that any updates made to the system do not impact the rest of the sync group. This step allows for independent updates to be applied without affecting the entire group.

Reconnecting the previously disconnected TMM switch ports and adding the GTM system back to the synchronization group will reintegrate the system with the rest of the group, allowing for synchronized updates to be applied across all systems. This step ensures that the system is once again part of the synchronization process.

Archiving

Explanation

The top-level domain (TLD) is the last part of a domain name, located after the last dot. In this case, ".com" is the TLD for the domain "www.f5.com".

Explanation

The client is not required to perform the "SOA" Record Lookup during the TCP connection. This lookup can be deferred to a later stage in the connection process, allowing for more flexibility and efficiency in the F5 GTM implementation.

Zone Transfer

Explanation

The "Bytes In" statistic in iQuery Statistics identifies the amount of data in bytes received by the BIG-IP DNS over the iQuery connection from the specified server. This metric helps monitor the incoming data flow and can be crucial in troubleshooting network performance issues related to data transfer.

iQuery Synchronization issue

Explanation

Recursive Query in DNS refers to the process where the DNS server will continue to query other servers on behalf of the client until it gets a resolution or an error message indicating that the Fully Qualified Domain Name (FQDN) doesn't exist. This means that the DNS server will not just provide a referral to another server but will actively seek the answer for the client.

In a Recursive Query, the DNS server itself will query other DNS servers to resolve the query on behalf of the client. This means that the DNS server takes full responsibility for finding the answer to the query and does not rely on the client to perform additional queries.

DNS Data flow

Explanation

When the BIGIP DNS System and other BIGIP Systems are located behind a firewall, the communication between them needs to be carefully configured. In this scenario, configuring the F5 BIGIP DNS System requires 2 mapped IP Addresses for the Server Object's address option to ensure proper communication between the systems behind the firewall. This setup allows for the necessary network connectivity and routing between the systems to function effectively.

Explanation

The correct command to check the health monitored named "New_monitor" with type http is "tmsh list /gtm monitor http New_monitor". This command specifically lists the details of the http monitor named "New_monitor" and provides information on its configuration and status.

Health Monitor

Explanation

The client has control over scheduling the Zone Transfer in F5 GTM Implementation. The client initiates the transfer process and determines when it should occur based on their specific requirements and preferences. This allows the client to manage and optimize the transfer process according to their needs.

Explanation

The correct command to monitor and check the status of a specific server using the tmsh Command Line utility is "tmsh show /gtm server ". This command will display detailed information about the specified server, including its current status, health, and any associated configurations.
