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

Explanation

The correct command to generate a new Certificate Signing Request (CSR) using OpenSSL is "openssl req -new -key -out ". This command specifies the creation of a new CSR, the location of the private key file, the output path and name for the CSR file, and the digest algorithm to be used for the CSR generation.

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.

Explanation

To display prober pools and probe requests in the Configuration Utility, you need to navigate to DNS > GSLB > Prober Pools > Prober Pool List > Statistics. This path will lead you to the relevant section where you can view information about prober pools and probe requests, allowing you to monitor and troubleshoot the probing process effectively.

Explanation

The correct choice is "Certificate Signing Request" (CSR). A CSR is a message sent from an applicant to a Certificate Authority (CA) to apply for a digital identity certificate. It contains information such as the public key, organization details, and domain name for which the certificate is being requested. The CA uses the CSR to create a certificate that will be used to secure communications on the network.

True. The UCS (User Configuration Set) file is a backup file that contains the entire configuration of the BIG-IP system. It is useful for backing up the configuration settings of the system and can be used to restore the system to a previous state in case of configuration errors or system failures.

Archiving

Explanation

When freezing the Zone file of the Zone, dynamic updates cannot occur. This means that any changes or updates to the Zone file will be restricted, ensuring that the Zone remains static and unchanged during the freeze period.

Freezing the Zone file does not impact normal name resolution. The DNS server will still be able to resolve domain names and provide the necessary information to clients, even though dynamic updates are disabled during this time.

The GTM Virtual Servers Configuration Object is a combination of an IP address and port number that directs traffic to a specific backend resource. This allows for load balancing and traffic management based on the specified IP address and port number.

The virtual server in GTM can be a member of different pools, allowing for flexibility in routing traffic to different backend resources based on specific criteria or conditions.

Explanation

The correct choice is A because the DNS Server informs the client that it will query other DNS Servers by setting the Recursion Available (RA) bit in the DNS message. This indicates to the client that the DNS Server is willing to perform recursive queries on behalf of the client and will query other DNS Servers if necessary.

DNS Data flow

Explanation

The 12th step in resolving the DNS query involves the client browser sending the HTTP request to the IP address of the target web server, in this case, http://www.f5.com. This step occurs after the DNS query has been resolved and the IP address of the target server has been obtained. The client browser then uses this IP address to establish a connection and send the HTTP request to the web server.

Explanation

The "-n" filter in the tcpdump command is used to disable the name resolution of the host. This means that instead of displaying hostnames, the command will show IP addresses, which can be useful for troubleshooting network issues without the delay of DNS lookups.
