QUESTION 91

During a disaster recovery test, several billing representatives need to be temporarily setup to take payments from customers. It has been determined that this will need to occur over a wireless network, with security being enforced where possible. Which of the following configurations should be used in this scenario?

 

A.

WPA2, SSID enabled, and 802.11n.

B.

WEP, SSID enabled, and 802.11b.

C.

WEP, SSID disabled, and 802.11g.

D.

WPA2, SSID disabled, and 802.11a.

 

Correct Answer: D

Explanation:

WPA2 is a security technology commonly used on Wi-Fi wireless networks. WPA2 (Wireless Protected Access 2) replaced the original WPA technology on all ce
rtified Wi-Fi hardware since 2006 and is based on the IEEE 802.11i technology standard for data encryption.

 

 

QUESTION 92

Wireless network users recently began experiencing speed and performance issues after access point 2 (AP2) was replaced due to faulty hardware. The original network was installed according to a consultant’s specifications and has always worked without a problem.

 

You a network technician, have been tasked with evaluating the situation and resolving the issues to improve both performance and connectivity. Refer to the following diagram and perform any Necessary changes to the wireless and wired infrastructure by adjusting devices.

 

Note. Adjust the LEAST number of devices needed to fix the issue all blue icons in the image are clickable.

Correct Answer:

AP2 configuration is not correct. The wireless mode should be ‘G’ and channel should be ‘11’. For the wired interface, the speed should be set to 100 and duplex to ‘Full’. Click ‘Submit’.

 

 

 

 

 

 

 

QUESTION 93

A user reports that some normally accessible external sites are not responding, but most other sites are responding normally. Which of the following is MOST likely the cause?

 

A.

VLAN tag mismatch

B.

Wrong subnet mask

C.

Smurf attack

D.

Faulty routing rule

 

Correct Answer: D

Explanation:

This happens when the DNS server is able to resolve the URL but there can be a conflicting route pointing to somewhere else rather than to the correct device who is responsible for routing traffic to the internet.

 

 

QUESTION 94

A customer wants to keep cost to a minimum and has only ordered a single static IP address from the ISP. Which of the following must be configured on the router to allow for all the computers to share the same public IP address?

 

A.

VLANs

B.

PoE

C.

PAT

D.

VPN

 

Correct Answer: C

Explanation:

Port Address Translation (PAT), is an extension to network address translation (NAT) that permits multiple devices on a local area network (LAN) to be mapped to a single public IP address. The goal of PAT is to conserve IP addresses.

 

 

QUESTION 95

A customer is having problems connecting to a wireless network in a shared office space. The customer can detect several other wireless network signals. All of the wireless networks have different SSIDs but several are using the same encryption type. Which of the following should be configured on the customer’s wireless network to improve connectivity to the wireless network?

 

A.

Change the SSID to match other wireless networks for increased throughput.

B.

Change the encryption type to a different mechanism to avoid interference.

C.

Change the channel to a different channel than the other wireless networks.

D.

Change the WAP to a different manufacturer than the other wireless networks.

 

Correct Answer: C

Explanation:

To reduce interference between wireless APs, ensure that wireless APs with overlapping signals use unique channel frequencies. The 802.11b standard reserves 14 frequency channels for use with wireless APs. You can use any other channel instead of the one that you are using.

 

 

 

 

 

QUESTION 96

Management wants to be sure that the existing wiring infrastructure conforms to CAT5e standards. Which of the following is the correct tool?

 

A.

Cable certifier

B.

Cable tester

C.

OTDR

D.

Protocol analyzer

 

Correct Answer: A

Explanation:

A.

Network

B.

Data Link

C.

Transport

D.

Physical

 

Correct Answer: B

Explanation:

The ITU-T G.hn standard, which provides high-speed local area networking over existing wires (power lines, phone lines and coaxial cables), includes a complete data link layer which provides both error correction and flow control by means of a selective repeat Sliding Window Protocol.

 

 

QUESTION 98

Which of the following port numbers is used for SNMP?

 

A.

61

B.

151

C.

161

D.

1611

 

Correct Answer: C

Explanation:

Simple Network Management Protocol (SNMP) is an “Internet-standard protocol for managing devices on IP networks”. Devices that typically support SNMP include routers, switches, servers, workstations, printers, modem racks, UPSes and more. It is used mostly in network management systems to monitor network-attached devices for conditions that warrant administrative attention.

 

 

QUESTION 99

Which of the following can function in an unsecure mode?

 

A.

SNMPv3

B.

SSH

C.

SSL

D.

SCP

 

Correct Answer: A

Explanation:

SNMPv3 makes no changes to the protocol aside from the addition of cryptographic security, it looks much different due to new textual conventions, concepts, and terminology.SNMPv3 primarily added security and remote configuration enhancements to SNMP

 

 

QUESTION 100

Given a subnet mask of 255.255.255.0, how many usable IP addresses would be in that subnet?

 

A.

250

B.

254

C.

255

D.

256

 

Correct Answer: B

Explanation:

The Subnet Mask however, determines the “class” of a Network. 255.255.255.0 is a “Class C” network.A class c network can host up to 254 pc’s
