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

Explanation

The root domain is the top-level domain in a fully qualified domain name (FQDN). In this case, the root domain is identified by the first dot at the right-hand side of the FQDN, which separates the top-level domain from the rest of the domain hierarchy.

Explanation

The Technical support will not support the case

there is no need file transfers , replication and additional testing

If remote access cannot be provided, the F5 Technical support team will resort to working directly with the Admin through phone or email to troubleshoot and resolve the issue. This allows for communication and collaboration between the support team and the Admin without the need for remote access.

In the absence of remote access, file transfers, replication, and additional testing may be required to diagnose and address the issue. This process may involve transferring files, replicating the issue in a controlled environment, and conducting further testing to identify the root cause.

If remote access is not possible, the Admin may be asked to provide the UCS Archive of the current configuration. This archive contains the configuration details of the system suffering from the issue, which can help the support team analyze and troubleshoot the problem without direct access to the system.

Explanation

When each of the BIGIP DNS System and other BIGIP System use public IP addresses to communicate with each other, the F5 BIGIP DNS System only requires a single IP address to be assigned to the Server Object's address option during the configuration. This is because using public IP addresses simplifies the communication setup and eliminates the need for multiple IP addresses.

The main function of the Zone file is to map the incoming DNS requests to the appropriate network resources. It contains information about the domain names and their corresponding IP addresses, allowing the DNS server to resolve queries and direct traffic to the correct destination.

As a required step to resolve the issue , What should be done if the issue involves the Network ?

A.The Admin should perform a packet trace during the occurrence of the issue and provide that trace when contacting the Technical Support

B.The Admin shouldn't make any thing

C.The Admin should close the case

Answer:A

Explanation

Performing a packet trace during the occurrence of the issue is crucial when troubleshooting network-related problems. The trace provides valuable information about the network traffic, potential bottlenecks, and any anomalies that could be causing the issue. Providing this trace to technical support helps them analyze the problem more effectively and identify the root cause.

Explanation

The SNMP Trap "bigipGtmPoolMbrDisabled" indicates that a global traffic manager pool member has been disabled. This trap is triggered when a pool member is manually disabled or automatically disabled due to health checks or other configuration settings. It serves as a notification that the specific pool member is no longer available for traffic distribution.

In the Configuration utility, to list a summary of iQuery Statistics, you need to navigate to the Statistics section, then select the module as Statistics, followed by DNS, GSLB, and then choose the Statistics Type as iQuery. This path will lead you to the summary of iQuery Statistics, allowing you to view relevant data and metrics related to iQuery operations.

Explanation

The top-level domain is managed by a delegated organization from IANA (Internet Assigned Numbers Authority). IANA is responsible for coordinating the global Internet's DNS root, IP addressing, and other Internet protocol resources.

Explanation

The command `openssl genrsa -out /config/ssl/ssl.key/f5BIGIPKEY.com_2024.key 2048` generates a private key with the name `f5BIGIPKEY.com_2024.key` in the specified directory `/config/ssl/ssl.key/`. This key is used for encryption and decryption processes in SSL/TLS communication.

Explanation

The correct explanation. DNS is designed to map Fully Qualified Domain Names (FQDN) to the corresponding IP addresses stored in large databases. This mapping allows users to access websites and services by typing in easy-to-remember domain names instead of complex numerical IP addresses.

Explanation

DNS can operate over either TCP or UDP, depending on the type of query and response. UDP is typically used for most DNS queries due to its speed and efficiency, while TCP is used for larger queries or responses that exceed the 512-byte limit of UDP.
