What are two ICMPv6 messages that are not present in ICMP for
IPv4? correct answer
* Neighbor Solicitation
* Destination Unreachable
* Host Confirmation
* Time Exceeded
* Router Advertisement
* Route Redirection
1) Neighbor Solicitation
2) Router Advertisement
A client packet is received by a server.
The packet has a destination port number of 80.
What service is the client requesting? correct answer
* DHCP
* SMTP
* DNS
* HTTP
HTTP
What is an advantage for small organizations adopting IMAP
instead of POP? correct answer
* POP only allows the client to store messages in a centralized
way, while IMAP allows distributed storage.
* Messages are kept in the mail servers until they are manually
deleted from the email client.
,* When the user connects to a POP server, copies of the
messages are kept in the mail server for a short time, but IMAP
keeps them for a long time.
* IMAP sends and retrieves email, but POP only retrieves email.
Messages are kept in the mail servers until they are manually
deleted from the email client.
IMAP and POP are protocols that are used to retrieve email
messages.
The advantage of using IMAP instead of POP is that when the
user connects to an IMAP-capable server, copies of the messages
are downloaded to the client application.
IMAP then stores the email messages on the server until the user
manually deletes those messages.
A technician can ping the IP address of the web server of a
remote company but cannot successfully ping the URL address of
the same web server.
Which software utility can the technician use to diagnose the
problem? correct answer
* tracert
* ipconfig
* netstat
* nslookup
nslookup
Nslookup is a utility that allows the user to manually query the
name servers to resolve a given host name.
This utility can also be used to troubleshoot name resolution
issues and to verify the current status of the name servers.
X) Traceroute (tracert) is a utility that generates a list of hops
that were successfully reached along the path from source to
destination.
,This list can provide important verification and troubleshooting
information.
Y) The ipconfig utility is used to display the IP configuration
settings on a Windows PC.
Z) The Netstat utility is used to identify which active TCP
connections are open and running on a networked host.
Which two functions are performed at the LLC sublayer of the
OSI Data Link Layer to facilitate Ethernet communication?
correct answer
implements CSMA/CD over legacy shared half-duplex media
enables IPv4 and IPv6 to utilize the same physical medium
integrates Layer 2 flows between 10 Gigabit Ethernet over fiber
and 1 Gigabit Ethernet over copper
implements a process to delimit fields within an Ethernet 2 frame
places information in the Ethernet frame that identifies which
network layer protocol is being encapsulated by the frame
1) enables IPv4 and IPv6 to utilize the same physical medium
2) places information in the Ethernet frame that identifies which
network layer protocol is being encapsulated by the frame
Explanation: The data link layer is actually divided into two
sublayers:
1) Logical Link Control (LLC): This upper sublayer defines the
software processes that provide services to the network layer
protocols.
1A) It places information in the frame that identifies which
network layer protocol is being used for the frame.
1A-1) This information allows multiple Layer 3 protocols, such as
IPv4 and IPv6, to utilize the same network interface and media.
2) Media Access Control (MAC): This lower sublayer defines the
media access processes performed by the hardware.
, 2A) It provides data link layer addressing and delimiting of data
according to the physical signaling requirements of the medium
and the type of data link layer protocol in use.
Other case:
Which two functions are performed at the LLC sublayer of the
OSI Data Link Layer to facilitate Ethernet communication?
correct answer
* responsible for internal structure of Ethernet frame
* applies source and destination MAC addresses to Ethernet
frame
* handles communication between upper layer networking
software and Ethernet NIC hardware
* adds Ethernet control information to network protocol data
* implements trailer with frame check sequence for error
detection
Other case:
1) handles communication between upper layer networking
software and Ethernet NIC hardware
2) adds Ethernet control information to network protocol data
