<div style="text-align: left;">
<span style="font-size: x-large;">I</span> recenlty came across a requirement for a client who wanted me to run a single DHCP Server for a multiple VLANs that I created for him. Apparently the last time I did that I was about to complete my Switiching module & honestly did not even think of anything that complicated. But to my surprise, it isn't all that hard to do so. A single command will let you do the magic & impress your client. </div>
<div style="text-align: left;">
</div>
<div style="text-align: left;">
This tutorial will show you how to configure dynamic IP address assignment on multiple VLAN with a unique DHCP server appliance on the network.</div>
Two VLANs are configured on Switch0 with Router0 as default gateway :<br />
<ul>
<li><span style="color: red;">VLAN 10 - Nework : 10.0.0.0/24 - Gateway : 10.0.0.1 (FA 0/0.10)</span></li>
<li><span style="color: red;">VLAN 20 - Network : 20.0.0.0/24 - Gateway : 20.0.0.1 (FA 0/0.20)</span></li>
</ul>

<strong>1</strong>. Which statement is true about the differences between a WAN and a LAN?<br />
WANs generally support higher bandwidth than LANs support.<br />
A WAN link typically traverses shorter geographic distances than a LAN link traverses.<br />
<span style="color: red;">A WAN often relies on the services of carriers, such as telephone or cable companies, but a LAN does not.</span><br />
All WAN implementations generally use the same Layer 2 protocol but there are many accepted LAN Layer 2 protocols in use.<br />
<br />
<strong>2</strong>. A U.S. company requires a WAN connection used only to transfer sales data from individual stores to the home office. All transfers will occur after business hours. The required bandwidth for this connection is estimated to be less than 38 kbps. Which type of connection requires the least investment for this company?<br />
ATM<br />
ISDN<br />

<span style="color: red;">DCE</span><br />
BRI<br />
PRI<br />
<br />
<strong>7</strong>. What is an advantage of packet-switched technology over circuit-switched technology?<br />
Packet-switched networks are less susceptible to jitter than circuit-switched networks are.<br />
<span style="color: red;">Packet-switched networks can efficiently use multiple routes inside a service provider network.</span><br />
Packet-switched networks do not require an expensive permanent connection to each endpoint.<br />
Packet-switched networks usually experience lower latency than circuit-switched networks experience.<br />
<br />
<strong>8</strong>. Which statement is true about data connectivity between a customer and a service provider?<br />
Normally the CSU/DSU is the designated demarcation point for the service provider but not the customer.<br />
<span style="color: red;">The segment between the demarcation point and the central office is known as the "last mile."</span><br />
The local loop is the segment between the CSU/DSU and the serial port on a <a href="http://ccnaanswers.com/" title="router">router</a>.<br />
Putting data on the local loop is the responsibility of the DTE.<br />
<br />
<strong>9</strong>. A company needs a WAN connection that is capable of transferring voice, video, and data at a minimum data rate of 155 Mbps. Which WAN connection is the best choice?<br />
X.25<br />
DSL<br />
<span style="color: red;">ATM</span><br />
ISDN BRI<br />
ISDN PRI<br />
<br />
<strong>10</strong>. Which statement is true of the functionality of the layers in the hierarchical network model?<br />
The purpose of the access layer is to provide very high bandwidth communications between network devices.<br />
Most security screening to prevent unauthorized entry to the network happens at the core layer.<br />
Untrusted external connections are segmented from the rest of the network at all three levels.<br />
<span style="color: red;">The distribution layer aggregates WAN connections at the edge of the campus.</span><br />
<br />
<strong>11</strong>. Why is the call setup time of a circuit-switched WAN implementation considered a drawback?<br />
Routing protocols are incompatible with this function.<br />
It restricts the communication sent to voice traffic only.<br />
A telephone must be used to initially start transferring data.<br />
<span style="color: red;">Data cannot be transferred until a circuit has been established.</span><br />
<br />
<strong>12</strong>. For digital lines, which device is used to establish the communications link between the customer equipment and the local loop?<br />

<span style="color: red;">PVC</span><br />
SPID<br />
<br />
<strong>17</strong>. Which statement about WAN protocols is correct?<br />
ATM differs from other WAN protocols in that it uses variably sized packets.<br />
<span style="color: red;">Most WAN protocols use HDLC or a variant of HDLC as a framing mechanism.</span><br />
The frame header consists of the frame check sequence and cyclic redundancy check.<br />
ISDN differs from Frame Relay, HDLC, and ATM in that it is packet-switched rather than circuit-switched technology.<br />

<strong>1</strong>. Which two statements are true regarding network security? (Choose two.)<br />
Securing a network against internal threats is a lower priority because company employees represent a low security risk.<br />
<span style="color: red;">Both experienced hackers who are capable of writing their own exploit code and inexperienced individuals who download exploits from the Internet pose a serious threat to network security.</span><br />
Assuming a company locates its web server outside the firewall and has adequate backups of the web server, no further security measures are needed to protect the web server because no harm can come from it being hacked.<br />
Established network operating systems like UNIX and network protocols like TCP/IP can be used with their default settings because they have no inherent security weaknesses.<br />
<span style="color: red;">Protecting network devices from physical damage caused by water or electricity is a necessary part of the security policy.</span><br />
<br />
<strong>2</strong>. Which two statements are true about network attacks? (Choose two.)<br />
Strong network passwords mitigate most DoS attacks.<br />
Worms require human interaction to spread, viruses do not.<br />
Reconnaissance attacks are always electronic in nature, such as ping sweeps or port scans.<br />
<span style="color: red;">A brute-force attack searches to try every possible password from a combination of characters.</span><br />
<span style="color: red;">Devices in the DMZ should not be fully trusted by internal devices, and communication between the DMZ and internal devices should be authenticated to prevent attacks such as port redirection.</span><br />

<strong>14</strong>. Clients across the company are reporting poor performance across all corporate applications running in the data center. Internet access and applications running across the corporate WAN are performing normally. The network administrator observes a continual broadcast of random meaningless traffic (jabber) on the application server LAN in the data center on a protocol analyzer. How should the administrator start troubleshooting?<br />
<span style="color: red;">The jabber in the data center indicates a local physical layer problem. Use the protocol analyzer to determine the source of the jabber, and then check for a recent NIC driver update or bad cabling.</span><br />
Because all clients are experiencing application problems, the administrator should use a top-down approach with the application servers in the data center.<br />
The scope of the problem indicates a likely routing or spanning-tree problem. Begin by checking routing tables, and follow up using appropriate STP <b>show</b> commands to find a loop if routing is working normally.<br />

<strong>14</strong>. What happens to a static route entry in a routing table when the outgoing interface is not available?<br />
<span style="color: red;">The route is removed from the table.</span><br />
The router polls neighbors for a replacement route.<br />
The route remains in the table because it was defined as static.<br />
The router redirects the static route to compensate for the loss of the next hop device.<br />
<br />
<strong>15</strong>. A router has one static route to each destination network. Which two scenarios would require an administrator to alter the static routes that are configured on that router? (Choose two.)<br />
<span style="color: red;">The destination network no longer exists.</span><br />
The destination network is moved to a different interface on the same router.<br />
The path between the source and destination is upgraded with a higher bandwidth link.<br />
<span style="color: red;">A topology change occurs where the existing next-hop address or exit interface is not accessible.</span><br />
The remote destination network interface has to be down for 15 minutes of maintenance.<br />
<br />
<strong>16</strong>. Why is it advisable to enter a next-hop IP address when creating a static route whose exit interface is an Ethernet network?<br />
Adding the next-hop address eliminates the need for the router to do any lookups in the routing table before forwarding a packet.<br />
<span style="color: red;">In a multi-access network, the router cannot determine the next-hop MAC address for the Ethernet frame without a next-hop address.</span><br />
Using a next-hop address in a static route provides a route with a lower metric.<br />
In multi-access networks, using a next-hop address in a static route makes that route a candidate default route.<br />
<br />

The company uses static routes and has a mixture of over 30 Cisco and non-Cisco routers. The network administrator has decided to convert the network to dynamic routing. What characteristics of protocols should be considered in this selection process?<br />
Distance vector routing protocols, such as RIP, converge more quickly than do link-state routing protocols.<br />
EIGRP can be used on all of the routers in the company.<br />
<span style="color: red;">OSPF can be used between the routers.</span><br />
An exterior routing protocol, such as BGP, is recommended for growing companies.<br />

Refer to the exhibit. Routers East and West are configured using RIPv1. Both routers are sending updates about their directly connected routes. The East <a href="http://ccnaanswers.com/" title="router">router</a> can ping the West router serial interface and West can ping the serial interface of East. However, neither router has dynamically learned routes from the other. What is most likely the problem?<br />
A gateway of last resort is required.<br />
Subnetting is not supported by RIPv1.<br />
<span style="color: red;">VLSM is not supported by RIPv1.</span><br />

Refer to the exhibit. RIPv1 is configured as the routing protocol for the network that is shown. The following commands are used on each router: <br />router rip <br />network 10.0.0.0 <br />network 172.16.0.0 <br />When this configuration is complete, users on the LAN of each router are unable to access the remote LANs. Why?<br />
The network statements are configured incorrectly.<br />
A routing loop has been created.<br />
<span style="color: red;">RIPv1 is unable to route to discontiguous subnets of a major network.</span><br />
RIPv1 is unable to route networks with a /24 subnet mask.<br />
<br />
<strong>7</strong>. A network administrator installed four new routers that are running RIPv2. Router1 is a boundary router in the RIPv2 network and has a default route configured. Once the network has converged, the network administrator enters Router1(config-router)# default-information originate on Router1. How will this affect the network?<br />
prevents Router1 from forwarding updates about networks that are not directly connected<br />
causes all routers in the network to synchronize routing updates with Router1<br />
forces Router1 to become the primary or designated router (DR) for updates<br />
<span style="color: red;">propagates the default route to all routers in the network</span><br />
