Questions and Answers
  • 1. 

    Hoe noemen we een machine die twee netwerken met elkaar verbindt? 

    • A.

      Repeater

    • B.

      Router

    • C.

      Hub

    • D.

      Switch

    Correct Answer
    B. Router
    Explanation
    A machine that connects two networks is called a router. A router is a networking device that forwards data packets between computer networks. It determines the best path for data packets to travel from one network to another, based on the destination IP address. Unlike a hub or a switch, a router can analyze the data packets and make intelligent decisions on how to route them to their destination. Therefore, a router is the correct answer for this question.

  • 3. 

    Hoe wordt het omzetten van de machinenaam www.brinkman-uitgeverij.nl in IPv4-adres 81.26.209.71 genoemd? 

    • A.

      Domain Name System

    • B.

      Name resolution

    • C.

      Domain name space

    • D.

      Resolver

    Correct Answer
    B. Name resolution
    Explanation
    Name resolution refers to the process of converting a domain name, such as www.brinkman-uitgeverij.nl, into its corresponding IPv4 address, which in this case is 81.26.209.71. This process is achieved through the use of the Domain Name System (DNS), which acts as a directory that translates domain names into IP addresses. Therefore, the correct answer for this question is "Name resolution."

    Rate this question:

  • 4. 

    Van welk zonetype kunnen onder Windows Server 2008 verschillende primaire DNS-zones bestaan? 

    • A.

      Primary

    • B.

      Secondary

    • C.

      Active Directory Integrated-Primary

    • D.

      Sub

    Correct Answer
    C. Active Directory Integrated-Primary
    Explanation
    Under Windows Server 2008, different primary DNS zones can exist for the Active Directory Integrated-Primary zonetype. This means that multiple primary DNS zones can be created and managed within the Active Directory Integrated zone, allowing for greater flexibility and control over DNS management. This zonetype integrates DNS functionality with Active Directory, providing enhanced security, replication, and ease of administration.

    Rate this question:

  • 5. 

    Kan een DNS-server meerdere forward lookup zones bevatten? 

    • A.

      Ja.

    • B.

      Ja, maar alleen als het Active Directory Integrated-Primary Zones zijn.

    • C.

      Nee, slechts één forward lookup zone en één reverse lookup zone zijn mogelijk.

    Correct Answer
    A. Ja.
    Explanation
    A DNS server can indeed contain multiple forward lookup zones. This allows the server to resolve different domain names to their respective IP addresses. However, it is important to note that this is only possible if the forward lookup zones are Active Directory Integrated-Primary Zones. These zones are stored in Active Directory and provide additional features and security. Therefore, the correct answer is "Ja."

    Rate this question:

  • 6. 

    Om te kunnen surfen op het internet moet uw client een verwijzing naar een DNS-server van het Internet hebben. 

    • A.

      Waar

    • B.

      Niet waar

    Correct Answer
    A. Waar
    Explanation
    To be able to surf the internet, your client device needs to have a reference to a DNS server. This server is responsible for translating domain names into IP addresses, allowing your device to connect to the correct website or server. Without a DNS server, your client would not be able to resolve domain names and therefore would not be able to access the internet. Therefore, the statement "Om te kunnen surfen op het internet moet uw client een verwijzing naar een DNS-server van het Internet hebben" is true.

    Rate this question:

  • 7. 

    Omdat Active Directory Integrated-Primary zones mee repliceren met AD, neemt het uitwisselen van DNS-gegevens tussen servers minder bandbreedte in beslag. 

    • A.

      Waar

    • B.

      Niet waar

    Correct Answer
    A. Waar
    Explanation
    The explanation for the given correct answer is that Active Directory Integrated-Primary zones replicate with AD, which means that the DNS data exchange between servers requires less bandwidth. This is because the DNS data is already integrated with the Active Directory infrastructure, allowing for efficient replication and synchronization of DNS information across servers.

    Rate this question:

  • 8. 

    U heeft tijdens het installeren van Active Directory op uw eerste DC gelijktijdig ook DNS laten installeren.   Welk IP-adres staat er daarna achter de verwijzing naar de DNS-server in het venster Internet Protocol Version 4 (TCP/IPv4) Properties

    • A.

      Het IP-adres van de DC zelf.

    • B.

      Het loopback address 127.0.0.1.

    • C.

      Geen, u moet zelf het IP-adres van de DC zelf invullen.

    • D.

      Geen, u moet zelf 127.0.0.1 invullen.

    Correct Answer
    B. Het loopback address 127.0.0.1.
    Explanation
    During the installation of Active Directory on the first domain controller, DNS was also installed simultaneously. As a result, the IP address behind the DNS server reference in the Internet Protocol Version 4 (TCP/IPv4) Properties window is the loopback address 127.0.0.1. This is because the DNS server is installed on the same machine as the domain controller, and the loopback address allows the machine to refer to itself.

    Rate this question:

  • 9. 

    Waarin wordt de DNS-naamruimte opgedeeld? 

    • A.

      In top-level domains.

    • B.

      In Fully Qualified Domain Names.

    • C.

      In DNS-zones.

    • D.

      In host names.

    Correct Answer
    C. In DNS-zones.
    Explanation
    The DNS-naamruimte, or DNS namespace, is divided into DNS-zones. A DNS-zone is a portion of the DNS namespace that is managed by a specific entity, such as an organization or a domain registrar. Each DNS-zone is responsible for managing the domain names and associated records within its designated portion of the namespace. This division allows for efficient management and delegation of domain names and ensures the scalability and functionality of the DNS system.

    Rate this question:

  • 10. 

    Waarom zou u een Secondary zone aanmaken in DNS? 

    • A.

      Omdat alleen een Secondary zone DNS fouttolerant maakt.

    • B.

      Omdat u een Secondary zone nodig heeft als uw bedrijf subdivisies bevat die los van het moederbedrijf opereren.

    • C.

      Voor DNS-fouttolerantie. Met Windows Server 2008 is een Secondary zone niet zo belangrijk omdat DNS ook fouttolerant gemaakt kan worden door Active Directory-Integrated Primary zones te gebruiken.

    • D.

      Voor DNS-fouttolerantie. In Windows Server 2008 is een Secondary zone niet zo belangrijk omdat DNS-fouttolerantie ook met Stub zones bereikt kan worden.

    Correct Answer
    C. Voor DNS-fouttolerantie. Met Windows Server 2008 is een Secondary zone niet zo belangrijk omdat DNS ook fouttolerant gemaakt kan worden door Active Directory-Integrated Primary zones te gebruiken.
    Explanation
    A Secondary zone is not as important in Windows Server 2008 because DNS can be made fault-tolerant by using Active Directory-Integrated Primary zones. This means that the DNS data is stored and replicated within the Active Directory infrastructure, providing redundancy and fault tolerance. Therefore, creating a Secondary zone is not necessary for DNS fault tolerance in Windows Server 2008.

    Rate this question:

  • 11. 

    Wanneer is een zone tranfer nodig? 

    • A.

      Als het Serial number uit het SOA-record van de primairy DNS-server hoger is als op de secondairy DNS-server.

    • B.

      Als het Serial number uit het SOA-record van de secondairy DNS-server hoger is als op de primairy DNS-server.

    Correct Answer
    A. Als het Serial number uit het SOA-record van de primairy DNS-server hoger is als op de secondairy DNS-server.
    Explanation
    A zone transfer is necessary when the serial number in the SOA record of the primary DNS server is higher than that on the secondary DNS server. This indicates that the primary DNS server has updated the zone information, and the secondary DNS server needs to synchronize its records with the updated information.

    Rate this question:

  • 12. 

    Wat is een belangrijk voordeel van Active Directory Integrated-Primary zones ten opzichte van primary zones? 

    • A.

      AD Integrated-Primary zones zijn redundante primary zones.

    • B.

      AD Integrated-Primary zones zijn meer geschikt om met secondary zones samen te werken dan primary zones.

    • C.

      AD Integrated-Primary zones werken sneller dan primary zones.

    • D.

      AD Integrated-Primary zones vereisen minder beheer dan primary zones.

    Correct Answer
    A. AD Integrated-Primary zones zijn redundante primary zones.
    Explanation
    AD Integrated-Primary zones zijn redundante primary zones. This means that they have built-in redundancy, which ensures high availability and fault tolerance. In case one server hosting the zone fails, another server can take over its responsibilities, ensuring that the zone remains accessible and functional. This redundancy is not available in regular primary zones, making AD Integrated-Primary zones a more reliable option.

    • C.

      PTR

    • D.

      SOA

    Correct Answer
    B. NS
    Explanation
    The NS (Name Server) resource record identifies another DNS server. This record is used to delegate a subdomain to a different set of name servers. It specifies the authoritative name servers for a particular domain, indicating which servers are responsible for handling DNS queries for that domain.

    Welk zonetype staat beveiligde updates toe in de DNS-database? 

    • A.

      Active Directory Integrated-Primary

    • B.

      Primary

    • C.

      Secondary

    • D.

      Geen van de hier genoemde

    Correct Answer
    A. Active Directory Integrated-Primary
    Explanation
    Active Directory Integrated-Primary is the correct answer because this zonetype allows for secure updates in the DNS database. With Active Directory Integrated-Primary, the DNS zone is stored in Active Directory and updates can be securely managed through Active Directory replication. This ensures that only authorized users can make changes to the DNS database, enhancing security and preventing unauthorized modifications.

    Welke uitspraak is waar? 

    • A.

      In een forward lookup zone wordt een IP-adres omgezet in een host name.

    • B.

      In een reverse lookup zone wordt een IP-adres omgezet in een host name.

    • C.

      In beide type zones wordt een IP-adres omgezet in een host name.

    • D.

      In beide type zones wordt een host name omgezet in een IP-adres.

    Correct Answer
    B. In een reverse lookup zone wordt een IP-adres omgezet in een host name.
    Explanation
    In a reverse lookup zone, an IP address is converted into a host name. This means that when a user provides an IP address, the reverse lookup zone will return the corresponding host name associated with that IP address. This is useful for troubleshooting and identifying the host or device associated with a particular IP address.

    Rate this question:

  • 20. 

    Om te testen laat u op een DNS-server een recursive query uitvoeren. Wat test u daarmee?

    • A.

      Of die DNS-server goed functioneert.

    • B.

      Of de andere DNS-servers waarmee u verbinding heeft goed functioneren.

    • C.

      Of uw internetverbinding goed functioneert.

    • D.

      Of uw internetrouter goed functioneert

    Correct Answer
    B. Of de andere DNS-servers waarmee u verbinding heeft goed functioneren.
    Explanation
    By performing a recursive query on a DNS server, you are testing whether the other DNS servers you are connected to are functioning properly. A recursive query involves the DNS server making multiple requests to other DNS servers in order to resolve a domain name. If the other DNS servers are functioning correctly, they will respond with the necessary information to resolve the query. Therefore, by successfully completing a recursive query, you can infer that the other DNS servers are functioning properly.
