Technical Terms - Internet (A-Z) - TTL

What does TTL stand for in computer networking?

• Time to Live

• Total Transmission Loss

• Transmitting Through LAN

• Total Time Lag

What is the purpose of TTL in data packets?

• To decrease data packet speed

• To increase data packet size

• To increase network performance

• To prevent packets from hopping indefinitely

What happens if a data packet's TTL count reaches 0 before reaching its destination?

• It is discarded by the router

• It is redirected to a different destination

• It is sent back to the sender

• It is stored in the cache

What is the range of the TTL count for a data packet?

• 200 to 300

• 100 to 200

• 1 to 255

• 0 to 100

What does a DNS server's TTL value control?

• How long it can serve a record before refreshing it

• The number of hops a packet can take

• The speed of data transmission

• The size of the cache

What is the purpose of a CDN server's TTL value?

• To control the number of assets stored

• To decrease server load

• To increase network latency

• To control how long it keeps a cached copy before checking for changes

What is the typical range for the TTL entries of DNS records?

• 1 second to 10 seconds

• 1 hour to 24 hours

• 30 seconds to 86,400 seconds

• 1 day to 7 days

Why is a TTL count necessary for data packets?

• To prevent network performance degradation

• To prevent data loss

• To increase data packet size

• To decrease data packet speed

What happens if a data packet's TTL count is set too low?

• It may take longer to reach its destination

• It may be discarded before reaching its destination

• It may cause network congestion

• It may be redirected to a different destination

How does a CDN server use TTL values for assets?

• To control the number of hops a packet can take

• To decrease network latency

• To increase server load

• To determine how long it keeps a cached copy before checking for changes
