10. What type of address is 169.254.32.23? A. APIPA B. Multicast Address C. Anycast Address D. Broadcast Address

A. APIPA Microsoft developed one type of private range for use on small peer-to-peer Windows networks. This private range, called Automatic Private IP Addressing (APIPA), uses a single Class B network number: 169.254.0.0.

5. Which port categories include inbound ports of HTTP, HTTPS, FTP, and DNS? A. Well-Known Ports B. Registered Ports C. Dynamic Ports D. Private Ports

A. Well-Known Ports Well-known ports are used when another computer wants to connect to a service or application running on your computer. These ports range from 0 to1023 and define commonly used protocols such as HTTP, HTTPS, FTP, and DNS.

9. You have a subnet mask of 255.255.240.0. What would the CIDR notation be? A. /16 B. /20 C. /24 D. /28

B. /20 One example of CIDR would be the IP network number 192.168.0.0/16. The /16 means that the subnet mask has 16 masked bits (or 1s), making 255.255.0.0. Usually, that would be a default Class B subnet mask, but because we are using it with what used to be a Class C network number, the whole address becomes classless.

7. How many layers does the TCP/IP model have? A. 3 B. 4 C. 6 D. 7

B. 4 The TCP/IP (or TCP) model is similar to the OSI model. It is often used by software manufacturers who are not as concerned with how information is sent over physical media, or how the data link is actually made. This model is composed of only four layers.

8. You are configuring the IPv6 network infrastructure for a branch office. The corporate network administrator allocates the 2001:DB8:0:C000::/58 address space for use in the branch office. You need to identify the maximum number of IPv6 subnets you can create. How many IPv6 subnets should you identify? A. 32 B. 64 C. 128 D. 1024

B. 64 IPv6 has 128-bit (16-byte) source and destination IP addresses. Although 128 bits can express over 3.4 x 1038 possible combinations, the large address space of IPv6 has been designed for multiple levels of subnetting and address allocation from the Internet backbone to the individual subnets within an organization.

2. What port number does Hypertext Transfer Protocol (HTTP) utilize? A. 20 B. 23 C. 80 D. 443

C. 80 HTTP uses port 80.

3. Your network contains an Active Directory domain. The domain contains a server named Server1 that runs Windows Server 2016 and has the DHCP Server server role installed. You need to create an IPv6 scope on Server1. The scope must use an address space that is reserved for private networks. The addresses must be routable. Which IPV6 scope prefix should you use? A. FF00:: B. 2001:: C. FD00:123:4567:: D. FE80::

C. FD00:123:4567:: Prefixes in the fd00::/8 range have similar properties as those of the IPv4 private address ranges: They are not allocated by an address registry and may be used in networks by anyone without outside involvement. They are not guaranteed to be globally unique. Reverse Domain Name System (DNS) entries (under ip6.arpa) for fd00::/8 ULAs cannot be delegated in the global DNS.

1. In what level of the TCP/IP model does the IP reside? A. Application Layer B. Transport Layer C. Internet Layer D. Link Layer

C. Internet Layer The Internet layer is where IP resides. IP is a connectionless protocol that relies on the upper layer (Transport layer) for guaranteeing delivery.

4. What is the network ID of the IP node 129.56.189.41 with a subnet mask of 255.255.240.0? A. 129.56.189.0 B. 129.56.176.1 C. 129.56.189.1 D. 129.56.176.0

D. 129.56.176.0 To obtain the result, turn both numbers into their binary equivalents and line them up. Then perform the AND operation on each bit and write down the result. 10000001 00111000 10111101 00101001 IP Address 11111111 11111111 11110000 00000000 Subnet Mask 10000001 00111000 10110000 00000000 Network ID The result of the bit-wise logical AND of the 32 bits of the IP address and the subnet mask is the network ID 129.56.176.0.5.

6. Your company has a main office and two branch offices. The offices connect to each other by using a WAN link. In the main office, you have a server named Server1 that runs Windows Server 2016. Server1 is configured to use an IPv4 address only. You need to assign an IPv6 address to Server1. The IP address must be private and routable. Which IPv6 address should you assign to Server1? A. fe80:ab32:145c::32cc:401b B. ff00:3fff:65df:145c:dca8::82a4 C. 2001:ab32:145c::32cc:401b D. fd00:ab32:14:ad88:ac:58:abc2:4

D. fd00:ab32:14:ad88:ac:58:abc2:4 The first 8 bits are always 11111101 in binary format. This means that a unique local address always begins with FD and a prefix identifier of FD00::/8.
