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

Explanation

Editing the DNS Profile feature "Logging" allows us to identify whether high-speed logging for DNS query and response is required. Enabling this feature can help in capturing and analyzing DNS traffic for troubleshooting and monitoring purposes.

If the "Logging" feature is enabled in the DNS Profile, it is recommended to also enable the logging profile to ensure that all DNS query and response data is captured and logged for analysis. Enabling both features together provides comprehensive visibility into DNS traffic.

Logging

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.

Natting

Explanation

A child Zone defines a subdomain of the Parent Zone, meaning it is a separate DNS zone that is part of a larger parent zone. This allows for delegation of authority and management of specific subdomains within the parent domain.

The physical representation of the child domain is not accurate in the context of a child Zone. A child Zone is a logical concept in DNS that represents a subdomain, not a physical representation of the domain.

F5 GTM Security

Explanation

True. The Configuration Files is one of the default files contained within a UCS (Unified Configuration Snapshot) by default. It includes important configuration settings and details that are essential for the operation and support of F5 GTM (Global Traffic Manager).

Domain

Archiving

Explanation

The main role of the Second Level Domain "f5.com" in "www.f5.com" is to resolve the IP Address of the specific subdomain "WWW". This domain helps direct the user to the correct server hosting the website content for "WWW".

Explanation

UDP port 688 is not the designated port for iQuery communication with the "big3d" process on other F5 BIGIP Systems. iQuery utilizes TCP Port 4353 for its communication needs, as UDP port 688 serves a different purpose and is not associated with the iQuery functionality.

NTP Port 554

Explanation

NTP Port 554 is unrelated to the communication between iQuery and the "big3d" process on other F5 BIGIP Systems. While NTP (Network Time Protocol) uses Port 123 for time synchronization, iQuery specifically utilizes TCP Port 4353 for its communication requirements with the "big3d" process.

iQuery communicates with the "big3d" process over TCP Port 4353 on other F5 BIGIP Systems. This port is specifically designated for iQuery communication, allowing for the exchange of information and commands between systems efficiently.

iQuery

Explanation

The GTM Screening mode Deployment type is named "Authoritative Screening Architecture" because it gives the ability to apply all GSLB features, allowing the Global Traffic Manager to effectively manage and optimize traffic distribution across multiple data centers or servers.

The GTM Screening mode Deployment type allows the GTM to receive all DNS queries, enabling it to load balance the incoming DNS queries to a pool of DNS servers. This ensures efficient distribution of traffic and optimal performance for the applications or services being accessed.

Domain

Load balancing types

Explanation

Round Robin DNS is the correct choice in this scenario because it is a method of load balancing where multiple IP addresses are associated with a single domain name. When a client requests the IP address for the domain, the DNS server responds with a different IP address each time in a rotating manner, distributing the traffic evenly among the servers. This helps in distributing the load and improving the overall performance and availability of the services.

Domain

F5 GTM concept

Explanation

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.

Technical Support

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.
