What is the main purpose of the Time to Live TTL field in a DNS query, and how does it affect the performance of DNS resolution? Question options: It is used to synchronize DNS servers, ensuring all have the same updated information. It limits the lifespan of a DNS query to prevent it from circulating indefinitely, improving DNS resolution efficiency by reducing unnecessary traffic. It restricts the number of queries a DNS server can handle in each time frame. It specifies the maximum time a domain can remain in the cache, thus increasing the likelihood of uptodate information but potentially slowing down DNS resolution.
