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

Explanation

Name Resolution or DNS Lookup is the process of translating a domain name (FQDN) into an IP address. This process involves querying DNS servers to find the corresponding IP address for the given FQDN, allowing devices to communicate over the network.

Name resolution

Explanation

Configuring a secondary load balancing type as a secondary option for the Primary Topology record ensures that the resolution process can continue even if the GTM fails to find the destination of the primary topology record. This redundancy helps maintain the operation of the resolution process and ensures that traffic can still be directed to the appropriate destination in case of any failures or issues with the primary load balancing configuration.

Explanation

The "commit_id" structure is linked to an MCP (Management Control Plane) Transaction in F5. When a configuration change is made in the Synchronization Group, the F5 device will operate according to this structure to apply the change. The MCP Transaction ensures that the configuration change is properly synchronized across the devices in the group.

iQuery - Synchronization Issues

Explanation

The main role of DNS is to resolve the queries received from end users by translating domain names (FQDN) into IP addresses. This allows users to access websites and services using human-readable domain names instead of numerical IP addresses.

Explanation

DNSSEC is indeed a standard protocol that adds a layer of security to the Domain Name System (DNS) by digitally signing DNS records to ensure their authenticity and integrity.

DNSSEC functions as an extension to the DNS protocol by adding cryptographic signatures to DNS records, allowing for validation of the data received from DNS servers to prevent DNS spoofing and other malicious activities.

F5 GTM Security

Explanation

Round Robin DNS is the correct choice because it is the DNS operation that involves assigning multiple IP addresses to the same Fully Qualified Domain Name (FQDN) in a rotating manner. This method allows for load balancing and distributing traffic among the different IP addresses associated with the FQDN.

Domain

F5 GTM concept

Explanation

The main task of the gtmd agent in the F5 GTM System is to use iQuery to communicate with the local big3d in the local F5 GTM System. This communication is essential for exchanging information and coordinating the functions of the GTM system within the local environment.

The gtmd agent in the F5 GTM System is responsible for using iQuery to communicate with the remote big3d on the other BIG-IP Systems. This communication is crucial for ensuring seamless coordination and synchronization of data and configurations across multiple BIG-IP Systems in a distributed environment.

iQuery

Explanation

The correct command to list the configuration for a monitor in F5 GTM is 'tmsh list /gtm monitor '. This command specifies the monitor type and name to retrieve the specific configuration details for that monitor, allowing administrators to view and verify the monitor settings.

Domain

Health Monitor

Explanation

The TMSH displays "Not connected" when there is a failing iQuery connection. This indicates that the connection between the iQuery and the system is not established or has encountered an issue, leading to the failure of the connection.

Domain

iQuery Synchronization issue

Explanation

The root domain is managed by the Internet Assigned Numbers Authority (IANA), which is responsible for the global coordination of the DNS Root, IP addressing, and other Internet protocol resources. IANA plays a crucial role in managing the root of the DNS hierarchy.
