Net+ subnetting and Routing

A networking student is learning that (AD) Administrative Distance rates the reliability of routing information received from neighboring routers. When multiple routes to the same network and subnet masks are received, the router prioritizes the route with the lower AD. However, if there are two identical network addresses, and each with a different subnet mask and both networks are configured with RIP and OSPF, how is the route determined?

• Routers will always choose the ‘smallest’ network (longest subnet mask) that an IP address matches first as a result of the different subnet masks.
• The router will look for the lowest administrative distance if two routing protocols have identical subnet masks for a destination.
• Once a routing protocol is chosen, the route with the lowest metric (hop count/cost) will be chosen.
• The path will depend on either RIP or OSPF.

Which of the following are true about (VLSM) Variable Length Subnet Masks? (Multiple Answers)

• VLSM does not allows for the customization of valid host addresses
• VLSM allows for the customization of valid host addresses
• The first step to subnetting VLSM is to sequence the number of hosts from highest to lowest
• The first step to subnetting VLSM is to sequence the number of hosts from lowest to highest

Marta's software company has recently merged with an online mail order company and as a result the new network system needs to be reconfigured. The new system will require 120 networking devices to include all employees and system upgrades. What subnet mask will provide enough usable IP addresses for the 120 networking devices?

• 255.255.255.128
• 255.255.255.192
• 255.255.255.224
• 255.255.255.240

Shelly is explaining networking routing concepts. What would she say are the two primary purposes of a router? (Multiple Answers)

• Determine the best path to its source based on the information in its routing table
• Determine the best path to its destination based on the information in its routing table
• Forward the data packets to their source by encapsulating packet into an ethernet frame
• Forward the data packets to their destination by encapsulating packet into an ethernet frame

Zeta has discovered that her Windows device has an incorrect subnet mask causing communication issues. How would Zeta verify her subnet mask?

• Ping 127.0.0.1
• Run traceroute
• View the ARP cache
• Use ipconfig /all to view network parameters

Barney has submitted a helpdesk ticket reporting that he is not able to connect to the internet after the implementation of network address translation. What should the system admin verify first to attempt to resolve the issue?

• Implement a static route to server
• Change the IP address to public
• Verify NAT configurations
• Modify the subnet mask

A network is using network address translation to allow multiple private IP addresses to share a single public IP address with the use of port numbers. What type of NAT has been configured? Hint: Command includes overload

• (PAT) Port Address Translation
• Static NAT
• Dynamic NAT
• NAT64

Ren and Kilo are trying to decipher NAT terms. What did they determine is the inside global address used in Network Address Translation?

• The source private address before translation
• The source public address after translation
• The destination public address before translation
• The destination private address before translation

Your gaming development organization requires devices to auto-configure their IPv6 addresses without a DHCP server. Which auto configuration method will be used to assign a device an IPv6 address after the EUI-64 has been calculated?

• Stateless DHCPv6
• Stateful DHCPv6
• SLAAC
• NAT64

How would Berty compress the IPv6 address: 2001: 0db8 : 0000 : ACBD : 1111 : 0000 : 0000 : 0200 Hint: 2 Rules

• 2001: 0db8 : 0 : ACBD : 1111 : 0 : 0 : 0200
• 2001: db8 : 0: ACBD : 1111 : : 200
• 2001: 0db8 : : ACBD : 1111 : : 0200
• 2001: db8 : 0 : ACBD : 1111 : 0 : 0 : 0200
