• Question 532:

  Which of the following DNS records is used to look up the IP address assigned to a domain name?

  A. A
  B. MX
  C. NS
  D. SPF
  A. A

  ---

  Explanation

  A DNS record is a data entry in a DNS server that maps a domain name to a specific value, such as an IP address, a mail server, a name server, or a text string. There are different types of DNS records for different purposes, and each type has a specific format and syntax12. The A record, also known as the address record, is the most common type of DNS record, and it is used to look up the IP address assigned to a domain name. The A record maps a domain name to an IPv4 address, which is a 32-bit numerical value that identifies a device on the internet. For example, the A record for www.google.com is 172.217.14.20612. The other options are not correct because they are not used to look up the IP address assigned to a domain name. The MX record, also known as the mail exchange record, is used to specify the mail servers that handle the email for a domain name. The MX record maps a domain name to a priority value and a host name of a mail server. For example, the MX record for gmail.com is 10 alt1.gmail-smtp-in.l.google.com12. The NS record, also known as the name server record, is used to delegate a domain name to a set of authoritative name servers. The NS record maps a domain name to a host name of a name server that can provide authoritative answers for the domain name and its subdomains. For example, the NS record for example.com is ns1.example.com12. The SPF record, also known as the sender policy framework record, is used to prevent email spoofing and spamming by validating the sender's identity. The SPF record maps a domain name to a text string that specifies the authorized mail servers and IP addresses that can send email on behalf of the domain name. For example, the SPF record for microsoft.com is v=spf1 include:spf.protection.outlook.com -all12.

  A. Scissors
  B. Network tap
  C. Magnetized screwdriver
  D. Tone generator
  E. RJ45 connector
  F. Crimper
  E. RJ45 connector
  F. Crimper

  ---

  Explanation

  To fix a Cat 5 cable issue where the cable fails when it is moved around, the technician would need to use an RJ45 connector (option E) and a crimper (option F). The technician can use the crimper to attach a new RJ45 connector to the end of the cable, which should resolve the issue. An RJ45 connector (option E) is a type of connector commonly used for Ethernet networking. It is an 8-position, 8-contact (8P8C) modular plug and jack that is used to terminate Cat 5 and other types of twisted pair cables. A crimper (option F) is a tool used to attach connectors to the ends of cables. In this case, the technician would use the crimper to attach a new RJ45 connector to the end of the Cat 5 cable. When a cable fails when it is moved around, it often indicates that there is a problem with the connector at the end of the cable. By attaching a new RJ45 connector using a crimper, the technician can ensure that the cable has a secure and reliable connection.
