It seems a rouge DHCP server was enabled on the network. The user's computer probably

received its lease from the rouge DHCP server, which does not have the same address pool as

the authorized DHCP server.

C: DNS is required for host name to IP address resolution. If the DHCP server loses connection to

the DNS server, it will not be able to lease IP addresses on the network. However, the IP

addresses that have been leased will still be in place.

A, D: WINS and DNS are required for NetBIOS name to IP address resolution and host IP

address resolution respectively. However, ping by IP address failed, therefore we cannot assume

that the problem is related to name resolution.

QUESTION NO: 9

A network administrator implements four VLANs (Virtual Local Area Network) on a switch. Which

device will be required to pass traffic among the VLANs (Virtual Local Area Network)?

A. No additional device needed

B. Router

C. A hub

D. Another switch

Answer: B

Explanation:

VLAN-capable switches use the switch management software to segment a network within the

switch itself. This saves you the expense of additional network hardware or recabling . However,

each VLAN corresponds to a different IP subnet. Therefore a router is required to change the

packets between VLANs, even though the destination host is connected to the same switch.

Incorrect Answers:

A: Although VLANs saves you the expense of additional network hardware or recabling, you do

need a router, because each VLAN corresponds to a different IP subnet. Therefore a router is

required to change the packets between VLANs.

C: A VLAN is created on a switch by assigning ports to a VLAN. It does not require the use an

additional switch or a hub.References:David Groth and Toby Skandier, Network+ Study Guide (4th

Edition), Sybex, Alameda CA, 2005, pp. 153-155.

QUESTION NO: 10

An administrator changes the lease time of the DHCP (Dynamic Host Configuration Protocol)

scope from one week to one day. What affect will this have on the end users?

A. The users will have to shut their computers down for the duration of the lease to obtain a new

lease.

B. The users will have to re-login every day now.

C. The users will not be affected by the change.

D. The users will have to manually release and renew their IP (Internet Protocol) addresses to

continue working on the network.

Answer: C

Explanation:

Changing the lease time will not affect the currently assigned IP configurations. The current IP

settings will still be valid but will now be renewed earlier. Thus, the users will not be affected by the

change.

Incorrect Answers:

A: This doesn't make sense in a network environment. If the lease time is increased to 30 days, no

work will be done for a month - definitely not!References:David Groth and Toby Skandier,

Network+ Study Guide (4th Edition), Sybex, Alameda CA, 2005, pp. 144, 154.

B: DHCP does not determine how often a user must re-logon to the computer. It only provides IP

configurations settings to the computer.

D: Changing the lease time will not affect the currently assigned IP configurations. The current IP

settings will still be valid but will now be renewed earlier.

QUESTION NO: 11

A network has been set up for DHCP (Dynamic Host Configuration Protocol) services using a PDC

(Primary Domain Controller) and BDC (Backup Domain Controller) each with a range of

192.168.0.1 to192.168.0.254 using a class subnet of 255.255.255.0. DHCP (Dynamic Host

Configuration Protocol) errors are occurring. How can the errors be resolved?

A. The machines are holding IP (Internet Protocol) addresses in cache memory. Reboot to renew

the IP (Internet Protocol) address.

B. Split the scope addresses between the servers assigning 192.168.0.1 through 192.168.0.127

for the PDC (Primary Domain Controller) and 192.168.0.128 through 192.168.0.254 for the BDC

C. Change the default subnet to 255.255.0.0 to increase the number of allowable IP (Internet

Protocol) addresses to prevent collisions.

D. ConfigureBootP (Boot Protocol) on the server when the IP (Internet Protocol) class subnets are

split prior to implementing the scope.

Answer: B

Explanation:

In this scenario, we have two DHCP servers leasing the same IP address scope. This is the cause

of the DHCP errors as both DHCP servers are trying to lease the same addresses. We can

overcome these problems by removing one of the DHCP servers, or by splitting the IP address

scope between the two.

Incorrect Answers:

A: DHCP leases are held for the duration of the DHCP lease period and are not renewed every

time the machine reboots. You must use the winipcfg/ipconfig/ifconfig utility to release and renew

a DHCP lease.

C: The IP address range 192.168.0.1 through 192.168.0.127 is a class C range which uses the

255.255.255.0 subnet mask. The subnet mask 255.255.0.0 is used for class B. Changing the

subnet mask to 255.255.0.0 would thus not be the correct option.

D: BootP is required to forward DHCP traffic over a router and should be configured on the router,

not the DHCP server.References:James Chellis, Paul Robichaux and Matthew Sheltz,

D. The amber light is flashing continually, the green light is lit steadily, and neither light will be on

until data is transferred.

Answer: A

Explanation:

A NIC has two lights: a green light that indicates network connectivity, and is lit so long as there is

network connectivity; and an amber light that flashes when collisions occurs. Collisions are

common on an Ethernet network. Therefore the amber light will flash occasionally.

QUESTION NO: 15

A network administrator manages a medium-sized network with a mixture of different platform

computers. The network contains multiple subnets located across a large geographical area. Over

half of the subnets contain a WAP (Wireless Access Point) for Internet access. The network

administrator has noticed that a particular subnets users have complained of downtime. Upon

further troubleshooting, the administrator notices that the each day the downtime lasts

approximately an hour around midday. The administrator also realizes that this period of downtime

is affecting wireless users only. The administrator travels to the troubled subnet around midday

and connects using a wired workstation, but a wireless laptop will not connect. The administrator

also notices that the WAP (Wireless Access Point) is 802.11g. Which one of the following would

be an appropriate action to address this problem?

A. Upgrade all affected computers to a uniform platform running in ad-hoc mode

B. During the affected time, connect the WAP (Wireless Access Point) directly into the router

C. Change the WAP (Wireless Access Point) and all affected computers to operate in ad-hoc

mode

D. Eliminate any sources of RFI (Radio Frequency Interference) around the WAP (Wireless

Access Point)

Answer: D

Explanation:

802.11g uses the 2.4 GHz range which is also used by appliances such as microwaves. The

connectivity problem occurs at around lunch time, which seems to indicate that the increased use

of microwaves at around this time is causing RFI (Radio Frequency Interference). We should thus

attempt to eliminate this RFI.

A company wishes to outsource the installation of an internal web server with access to

employees only. Which term BEST describes this web server?

A. Extranet server

B. VPN (Virtual Private Network) server

C. RADIUS (Remote Authentication Dial-In User Service) server

D. Intranet server

Answer: D

Explanation:

An intranet is made up of all networks under a single administrative control and can be thought of

as an internal internetwork. Thus resources made available to intranet users are only available to

users on that internetwork. In this scenario we want an internal web server to be accessible to

employees only. This would be an intranet server.

Incorrect Answers:

A: An extranet is similar to an intranet, which is made up of all networks under a single

administrative control. The exception is that an extranet is and expansion of the intranet to include

a few external or outside networks. In this scenario we want an internal web server to be

accessible to employees only, and not to outside users.

B: A VPN is a connection between two systems that uses the Internet as its backbone.

C: A RADIUS server is an authentication server used to authenticate remote dial-up

connections.Reference:David Groth and Toby Skandier, Network+ Study Guide (4th Edition),

Which disaster recovery implementation is the MOST expensive?

A. Hot site

B. Cold site

C. Dynamic site

D. Warm site

Answer: A



Actu

alTe

sts.

com

Explanation:

In a hot site, every computer system and every bit of information has a redundant copy. This

provides 100% fault tolerance for systems that must be up 100% of the time. Hot sites are strictly

fault-tolerant implementations, not disaster recovery implementations. Budgets for this type of fault

tolerant implementation are typically large because each computer system must have a redundant

copy.

Incorrect Answers:

B: Cold sites rely on back ups for data recovery. This implementation has no fault tolerance and,

hence, no expense, except for back up equipment.

C: There is no dynamic site in fault tolerant or disaster recovery

implementations.References:David Groth and Toby Skandier, Network+ Study Guide (4th Edition),

Sybex, Alameda CA, 2005, pp. 369-372.

D: Warm sites are not as expensive as hot sites because it requires redundant copies on critical

network components, such as servers, rather than redundant copies of all computer systems.

C. IP (Internet Protocol) address, subnet mask, gateway, and DNS (Domain Name Service)

D. Subnet mask, IP (Internet Protocol) address, and DNS (Domain Name Service)

Answer: C

Explanation:

Every host on a TCP/IP network needs a unique IP address and a subnet mask. To connect to the

Internet, the host also needs a gateway, which is an intermediate device that provides connectivity

to an external or dissimilar network. To be able to reach hosts on the internet, the host will need

DNS to resolve host names to IP addresses.

Incorrect Answers:

A: The host also needs a subnet mask.References:David Groth and Toby Skandier, Network+

Study Guide (4th Edition), Sybex, Alameda CA, 2005, pp. 33, 125-131, 136, 138-139, 145-147.

B: The host also needs a subnet mask, and a gateway, which provides connectivity to an external,

In order for a client to share resources on a wired network, the client must be physically connected

and:

A. be a member of AD (Active Directory).

B. allowed permission to the resources.

C. be listed in DNS (Domain Name Service).

D. mapped to the resources using the host name, followed by the resource name.

Answer: B

Explanation:

A client cannot share resources on a wired network that it does not have access to, and access is

controlled through permissions. Thus, a client needs permissions to a resource before they can

share that resource.

Incorrect Answers:

A: AD is a database. It is not a group to which a client can have membership. However, the client

must have a user account in AD.

C: DNS is used for name resolution, not for sharing of resources.References:David Groth and

Toby Skandier, Network+ Study Guide (4th Edition), Sybex, Alameda CA, 2005, pp. 138-142, 204-

D: The mapping of resources is accomplished through AD and DNS. Therefore, the client does not

need to map the resource by host name and resource name.

The DHCP (Dynamic Host Configuration Protocol) server in Subnet A is removed. The DHCP

(Dynamic Host Configuration Protocol) server in Subnet B is set with a DHCP (Dynamic Host

Configuration Protocol) scope for Subnet A. After that, users in Subnet A still cannot receive IP

(Internet Protocol) addresses. What needs to be done to correct this problem?

A. Install a DHCP (Dynamic Host Configuration Protocol) relay agent on a server in Subnet B

B. Install a DHCP (Dynamic Host Configuration Protocol) relay agent on the DHCP (Dynamic Host

Configuration Protocol) server in Subnet B

C. Install a proxy server on Subnet A

D. Install a DHCP (Dynamic Host Configuration Protocol) relay agent on a server in Subnet A

Answer: D

Explanation:

The DHCP server in Subnet A failed so we can assume that the DHCP clients on Subnet A cannot

reach a DHCP server to renew their DHCP leases. This can be overcome by installing a DHCP

relay agent on the affected subnet.

Note: This is a vague question. The real problem here is that the DHCP server in Subnet B has a

DHCP address but the other DHCP server has failed. This means that the DHCP server in Subnet

B cannot get a DHCP lease, unless there is another DHCP server on the network. We should

preferably configure the DHCP server with a static IP address.

Incorrect Answers:

A: The DHCP server in Subnet A failed so we can assume that the DHCP clients on Subnet A

cannot reach a DHCP server to renew their DHCP leases. This can be overcome by installing a

DHCP relay agent on the network. However, the DHCP relay agent should be installed on the

affected Subnet, not Subnet B.References:James Chellis, Paul Robichaux and Matthew Sheltz,

If a destination address is not in a bridges forwarding table, what will the bridge do?

A. Forward the packet to all ports

B. Forward the packets to a designated port and the one that originated the request

C. Forward the packets to all ports except the one that originated the request

D. Forward the packets to the default gateway

Answer: C

Explanation:

Bridges read each frame as it passes through it. It then puts the source hardware address in a

forwarding table and keeps track of which port the frame was received on, to determine the

location of the sending device. Once a forwarding table is built, the bridge will only forward frames

to the segment where the destination hardware address is located. If the destination device is on

the same segment as the frame, the bridge will block the frame from going to any other segments.

If the destination address is on a different segment, the frame will only be transmitted to that

segment. However, if the destination address is not on bridge's forwarding table, it broadcasts the

packet through all ports.

QUESTION NO: 230

A rogue residential gateway has been installed in a network. It is running DHCP (Dynamic Host

Configuration Protocol). If the computers have static IP (Internet Protocol) addresses assigned,

what problems might exist on the network?

A. There will be a routing loop between the residential gateway and the original router.

B. The computer IP (Internet Protocol) addresses will change.

C. There should be no problems.

D. There will be no Internet access.

Answer: D

Explanation:

The network computers have statically assigned IP addresses, the gateway address might not be

configured, in which case the network computers might use the rouge gateway and would thus,

not be able to connect to the Internet.

Incorrect Answers:

B: The network computers' IP addresses are static addresses and can only be changed manually.

The presence of a rogue residential gateway will not change the static IP addresses.

C: There would be no problems is the gateway address was configured statically on the network

computers. However, the gateway address is not required for static IP addressing; only the IP

address and subnet mask is required. Thus, if the gateway address is not configured, the network

computers might use the rouge gateway and would not be able to connect to the Internet.
