4. Question
3 pointsWhich three configuration components are required to allow a host to communicate with other hosts on remote networks? (Choose three.)
Correct
Incorrect
An IP address, a subnet mask, and a default gateway are required on a host that must communicate with another host in a remote network. DNS server information is needed if mapping a domain name to an associated IP address. DHCP server information is dynamically learned and is not a required configuration for remote network reachability.

15. Question
1 pointsWhat is the full uncompressed representation of the IPv6 address 2001:DB8:0:0:AA::200?
Correct
Incorrect
An IPv6 address is made up of 128 bits represented in hexadecimal numbers.There are two rules that help reduce the number of digits needed to represent an IPv6 address.Rule 1 – Omit leading zeros in any 16-bit section.
Rule 2 – Replace any single group of consecutive zeros with a double colon (::). This can only be used once within an IPv6 address.Hint

18. Question
2 pointsWhich two application layer protocols manage the exchange of messages between a client with a web browser and a remote web server? (Choose two.)
Correct
Incorrect
Hypertext Transfer Protocol (HTTP) and HTTP Secure (HTTPS) are two application layer protocols that manage the content requests from clients and the responses from the web server. HTML (Hypertext Mark-up Language) is the encoding language that describes the content and display features of a web page. DNS is for domain name to IP address resolution. DHCP manages and provides dynamic IP configurations to clients.

Question 20 of 26
20. Question
1 pointsHow much data can be encapsulated into a normal sized Ethernet frame before it is sent over the network?
Correct
Incorrect
According to the Ethernet standards, each Ethernet frame can carry 46 to 1500 bytes of user data. During the encapsulation process, other fields are added, such as destination MAC address, source MAC address, and FCS. The size of Ethernet frames is normally limited to a maximum of 1518 bytes and a minimum of 64 bytes.

1 pointsWhich transport layer protocol provides best effort delivery without guaranteeing that packets arrive at the destination?
Correct
Incorrect
User Datagram Protocol (UDP) is a best effort transport layer protocol. Unlike TCP, it does not use an acknowledgment protocol to ensure reliable packet delivery. TCP provides reliable delivery service. HTTP and SSH are application layer protocols in the TCP/IP model.

Question 24 of 26
24. Question
1 pointsWhen a host sends a packet, how does it determine if the destination of the packet is on the same local network or on a remote network?
Correct
Incorrect
When a host sends a packet, it uses the subnet mask to compare the source IPv4 address and the destination IPv4 address. If the network bits match, both the source and destination host are on the same local network. Otherwise, the destination host is on a remote network.
