A campus needs a network link between two buildings. Which design choice best fits the guidance for selecting Ethernet media?

  1. A

    Use ordinary endpoint copper cabling regardless of distance or equipment.

  2. B

    Choose fiber and transceivers that match the required speed, distance, and equipment.

  3. C

    Use a Wi-Fi access point as the physical link between the buildings.

  4. D

    Choose the cable type based only on the IP subnet assigned to the link.

A design must forward packets between two different IP networks. Which device role directly performs this function according to the network design guidance?

  1. A

    A wireless access point, because it forwards all packets between IP networks.

  2. B

    A router, which forwards packets between IP networks using IP addresses.

  3. C

    An Ethernet switch, because it forwards frames between networks using MAC addresses.

  4. D

    A firewall, because traffic rules alone create the routes between networks.

A staff LAN needs 50 IPv4 host addresses. Under conventional host-counting, why is the example 192.168.40.0/26 subnet sufficient?

  1. A

    It has 62 usable host addresses after reserving the network and broadcast addresses.

  2. B

    It has 50 total addresses, one for each staff member.

  3. C

    It has 64 usable host addresses because conventional subnets do not reserve any addresses.

  4. D

    It has 30 usable host addresses, which is enough for the staff network.

  3. C

    192.168.0.0/16

    172.32.0.0/12

A client cannot reach a service using IPv6, although IPv4 access works. Select all checks supported by the troubleshooting guidance. Include DNS checks only if the service is accessed by hostname.

  1. A

    Verify the host's IPv6 address and prefix.

  2. B

    Check the host's IPv6 default route and the router's IPv6 interface and route.

  3. C

    Check IPv6-specific firewall policy.

  4. D

    Verify that the service listens on IPv6.

  5. E

    If accessing the service by hostname, check its DNS records.

  6. F

    Assume the IPv4 default gateway provides the IPv6 route automatically.

An organization needs a high-speed Ethernet link between buildings. Which choice best fits the guidance for selecting link media?

  1. A

    Twisted-pair copper, regardless of distance

  2. B

    Fiber with transceivers matched to the required link

  3. C

    A wireless access point in place of the link

  4. D

    An IPv6 prefix

A workstation can reach a service by its IP address but not by its hostname. Which should be investigated first?

  1. A

    The Ethernet cable, because hostnames use a separate link

  2. B

    The VLAN, because DNS is not used after IP configuration

  3. C

    DNS, because the IP destination works but the hostname does not

  4. D

    The default gateway, because it assigns hostnames to applications

  3. C

    A longer Ethernet cable

  1. A

    Exclude the statically assigned addresses from the DHCP pool

  2. B

    Move the DHCP pool into a different VLAN without checking addresses

  3. C

    Change the Ethernet standard

A network designer proposes 2001:db8::/32 for a production IPv6 deployment. Which response is correct?

  1. A

    Use it as the required prefix for every production LAN

  2. B

    Use it only for a subnet that needs IPv4 broadcast addressing

  3. C

    Do not use it for production addressing; it is reserved for documentation and examples

  4. D

    Use it only as an IPv4 private range
