Answer: 
* traceroute (tracert) outputs the list of
traversed routers in simple text format, together with timing information
* Q: How is it possible for traceroute to
timeout, yet the site will load fine in a browser?
If a router along the way decides to not send
the ICMP error message, you will get a timeout at that point in the traceroute.
The router may pass on normal traffic, thus
allowing your TCP-based http request to complete, but it may silently drop ICMP
requests or errors, leaving your local traceroute process waiting and then
timing out on that stop.

With a recursive name query , the DNS client
requires that the DNS server respond to the client with either the requested
resource record or an error message stating that the record or domain name does
not exist. The DNS server cannot just refer the DNS client to a different DNS
server.
* No. * Yes.
An iterative name query is one in which a DNS
client allows the DNS server to return the best answer it can give based on its
cache or zone data. If the queried
DNS server does not have an exact match for the
queried name, the best possible information it can return is a referral (that
is, a pointer to a DNS server authoritative for a lower level of the domain
namespace). The DNS client can then query the DNS server for which it obtained
a referral. It continues this process until it locates a DNS server that is
authoritative for the queried name, or until an error or time-out condition is
met.

Correct Answer: 
* TRACERT prints out an ordered list of the
routers in the path that returned the ICMP Time Exceeded message.
* Ping, not tracert, determines packet loss.
* Tracert just displays the path to the target,
not all connections.
Note -
* Example:
tracert 11.1.0.1
Tracing route to 11.1.0.1 over a maximum of 30
hops
1 2 ms 3 ms 2 ms 157.54.48.1
2 75 ms 83 ms 88 ms 11.1.0.67
3 73 ms 79 ms 93 ms 11.1.0.1
Trace complete.
* The TRACERT diagnostic utility determines the
route taken to a destination by sending Internet Control Message Protocol
(ICMP) echo packets with varying IP
Time-To-Live (TTL) values to the destination.
Each router along the path is required to decrement the TTL on a packet by at
least 1 before forwarding it, so the
TTL is effectively a hop count. When the TTL on
a packet reaches 0, the router should send an ICMP Time Exceeded message back
to the source computer.

Correct Answer: 
* Dynamic Routing. A router with dynamically
configured routing tables is known as a dynamic router. Dynamic routing
consists of routing tables that are built and maintained automatically through
an ongoing communication between routers.
* Most of the dominant routing algorithms are
dynamic routing algorithms, which adjust to changing network circumstances by
analyzing incoming routing update messages. If the message indicates that a
network change has occurred, the routing software recalculates routes and sends
out new routing update messages.
These messages permeate the network, stimulating
routers to rerun their algorithms and change their routing tables accordingly.
* When there are multiple routes to the same
destination, a router must have a mechanism for calculating the best path. A
metric is a variable assigned to routes as a means of ranking them from best to
worst or from most preferred to least preferred.

* (C) Confinement of broadcast domains on a

By confining the broadcast domains, end-stations
on a VLAN are prevented from listening to or receiving broadcasts not intended

VLANs, the end-stations of a VLAN cannot communicate with the end-stations of
the other VLANs.

Network
bridging is the action taken by network equipment to create an aggregate network
from either two or more communication networks, or two or more network
segments. If one or more segments of the bridged network are wireless, it is
known as wireless bridging.
* Yes.
In Wi-Fi,
repeater mode is a variation on bridging. Rather than join multiple LANs,
repeater mode is intended mainly to increase the range of a single wireless LAN
by extending the same wireless signal.
* No.
In Wi-Fi
networking, bridging mode allows two or more wireless access points (APs) to
communicate with each for the purpose of joining multiple LANs.

QoS traffic control: Regulate data flows by
classifying, scheduling, and marking packets based on priority and by shaping
traffic (smoothing bursts of traffic by limiting the rate of flow). Traffic
control mechanisms segregate traffic into service classes and control delivery
to the network. The service class assigned to a traffic flow determines the QoS
treatment the traffic receives.
* Yes.
The goal of QoS is to provide preferential
delivery service for the applications that need it by ensuring sufficient bandwidth,
controlling latency and jitter, and reducing data loss.

* Yes.
The network layer provides the functional and
procedural means of transferring variable length data sequences (called
datagrams) from one node to another connected to the same network. It
translates logical network address into physical machine address. A network is
a medium to which many nodes can be connected, on which every node has an
address and which permits nodes connected to it to transfer messages to other
nodes connected to it by merely providing the content of a message and the
address of the destination node and letting the network find the way to deliver
("route") the message to the destination node.

Network client computers running Windows 8.1 and
Windows 10 are configured to receive IPv4 addresses through DHCP. The DHCP
server fails.
For each of the following statements, select Yes
if the statement is true. Otherwise, select No.
Hot Area:
Correct Answer: Explanation
The IpReleaseAddress and IpRenewAddress
functions are used to release and renew the current Dynamic Host Configuration
Protocol (DHCP) lease. The
IpReleaseAddress function releases an IPv4
address previously obtained through DHCP. The IpRenewAddress function renews a
lease on an IPv4 address previously obtained through DHCP. It is common to use
these two functions together, first releasing the lease with a call to
IpReleaseAddress, and then renewing the lease with a call to the IpRenewAddress
function.
When a DHCP client has previously obtained a
DHCP lease and IpReleaseAddress is not called before the IpRenewAddress
function, the DHCP client request is sent to the DHCP server that issued the
initial DHCP lease. This DHCP server may not available or the DHCP request may
fail. When a host has previously obtained a DHCP lease and IpReleaseAddress is
called before the IpRenewAddress function, the DHCP client first releases the
IP address obtained and sends a
DHCP client request for a response from any
available DHCP server.

Your
network uses routers configured with the RIP router protocol.
For each of the following statements, select Yes
if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.
Hot Area:
Correct Answer: Explanation
Routing Information Protocol (RIP) uses hop
count as the metric to rate the value of different routes. The hop count is the
number of devices that can be traversed in a route. A directly connected
network has a metric of zero; an unreachable network has a metric of 16. This
limited metric range makes RIP unsuitable for large networks.
The Routing Information Protocol (RIP) sends
routing-update messages at regular intervals and when the network topology
changes. When a device receives a
RIP routing update that includes changes to an
entry, the device updates its routing table to reflect the new route. The
metric value for the path is increased by 1, and the sender is indicated as the
next hop. RIP devices maintain only the best route (the route with the lowest
metric value) to a destination. After updating its routing table, the device
immediately begins transmitting RIP routing updates to inform other network
devices of the change. These updates are sent independently of the regularly scheduled
updates that RIP devices send.
Summarizing routes in RIP Version 2 improves
scalability and efficiency in large networks. Summarizing IP addresses means
that there is no entry for child routes
(routes that are created for any combination of
the individual IP addresses contained within a summary address) in the RIP
routing table, reducing the size of the table and allowing the router to handle
more routes.
It is a stable protocol that uses a
distance-vector algorithm to calculate routes.
