What does DNSSEC stand for?

• Domain Name Security System Encryption

• Domain Name System Security Extensions

• Dynamic Name System Security Encryption

• Digital Network Security System Extension

How does DNSSEC improve security?

• By increasing the speed of DNS resolution

• By blocking access to certain websites

• By encrypting all DNS queries

• By validating the authenticity of the DNS data

What was the original domain name system lacking in terms of security?

• Minimal security measures

• Validation of name servers

• Digital signatures for queries and responses

• Authentication of DNS data

What is used to create a chain of trust in DNSSEC?

• IP address validation

• Hashed DNS records

• Delegation signer records

• Public/private key pair

Which type of servers generate the public key in DNSSEC?

• DNS zone servers

• Proxy servers

• Web servers

• Mail servers

What is required to enable DNSSEC on a server?

• Activating DNSSEC on the client side

• Using a nameserver that supports it

• Creating a chain of trust

• Configuring it within the control panel interface

How long may it take to activate DNSSEC after enabling it?

• Several days

• Several hours

• Depends on the server location

• Instantly

Which nameservers support DNSSEC?

• Apache and Nginx

• PowerDNS and Knot DNS

• PHP and Python

• MySQL and PostgreSQL

What is used to authenticate queries and responses in DNSSEC?

• API key

• Access token

• SSL certificate

• Digital signature

What is the purpose of a delegation signer (DS) record in DNSSEC?

• To generate public keys for DNS zones

• To enable DNSSEC on public nameservers

• To validate DS records with other servers

• To manually create records for custom nameservers
