A) Firewall
B) Switch
C) Modem
D) IDS

Accepted Answer

A switch is necessary to connect multiple devices within the building to the corporate network, allowing them to communicate with each other and access the core network.

Question 10

A technician has started a major network project to upgrade to a higher throughput standard. The technician will need to install new patch panels and breakout boxes to support this infrastructure. Which of the following layers of the OSI model is the technician addressing at this stage of the upgrade?
A) Physical
B) Transport
C) Network
D) Data link

Accepted Answer

The technician is addressing the Physical layer of the OSI model, as this layer deals with the physical infrastructure, including cables, patch panels, and breakout boxes.

Question 11

A network technician installs a new Layer 3 switch in the accounting office. Which of the following should the technician configure on the switch to enhance network security?
A) Spanning tree
B) Access control list
C) QoS settings
D) Duplex settings

Accepted Answer

Access control lists (ACLs) are used to enhance network security by controlling the traffic that is allowed to enter or leave a network, based on specified criteria.

Question 12

Which of the following technologies is used to translate one public IP address to multiple private IP addresses?
A) NAT
B) ARP
C) DHCP
D) DNS

Accepted Answer

NAT (Network Address Translation) is a technology that allows multiple private IP addresses to be translated to a single public IP address. This is done to conserve public IP addresses and to provide security for private networks.

Question 13

A network technician has established an internal HTTP connection from a browser to the web server to access an organization's intranet services. In which of the following layers of the OSI model is the HTTP protocol found?
A) Session
B) Data link
C) Network
D) Application

Accepted Answer

HTTP is found in the Application layer of the OSI model, which is responsible for network services to applications.

Question 14

An organization has migrated the internal network from a static IP addressing scheme to use DHCP. After fully deploying the DHCP solution, users within the web deployment team are unable to access the web server that is hosted in the DMZ. After reviewing the logs, the network technician sees multiple deny entries from the internal network to the DMZ. Which of the following is the MOST likely cause?
A) The DNS entries are incorrect for the web development team.
B) The server IP addresses in the DMZ have changed after migrating to DHCP.
C) The OSPF configuration was not updated to route the new dynamic address spaces.
D) The ACL does not accurately reflect current addresses for the web development team.

Accepted Answer

The ACL (Access Control List) likely contains static entries that do not match the new dynamic IP addresses assigned by DHCP, causing the deny entries in the logs.

Question 15

A wireless engineer installs a new 802.11g access point in a new part of a building. Users begin reporting slow connections, even with a strong signal. The engineer uses a packet analyzer and sees retransmitted and malformed packets, as well as some malformed WiMax packets. Which of the following issues is described?
A) Refraction
B) Interference
C) Latency
D) Overcapacity

Accepted Answer

Interference is likely the issue because the presence of malformed WiMax packets suggests that there is interference from another wireless technology operating in the same frequency range, affecting the 802.11g network.

Question 16

Which of the following provides redundancy on a file server to ensure the server is still connected to a LAN even in the event of a port failure on a switch?
A) NIC teaming
B) Load balancer
C) RAID array
D) PDUs

Accepted Answer

NIC teaming allows multiple network interfaces to be combined into a single logical interface, providing redundancy and failover capabilities in case of a port failure on a switch.

Question 17

A security team needs to restrict access to a wireless network in a certain area. Which of the following would be used to enforce this restriction?
A) Geofencing
B) WPA2-PSK
C) EAP-TLS
D) VLAN tagging

Accepted Answer

Geofencing is a technology that creates a virtual boundary around a specific geographic area, allowing the security team to restrict access to the wireless network based on location.

Question 18

A network administrator is investigating an issue with VoIP calls that are not establishing properly. After troubleshooting, the administrator is able to determine the SIP responses are not being received by the gateway. Which of the following did the administrator use to determine this information?
A) netstat
B) A spectrum analyzer
C) tracert
D) A packet analyzer

Accepted Answer

A packet analyzer is used to capture and analyze network traffic, which would allow the administrator to see if SIP responses are being received by the gateway.

Question 19

A network engineer is planning to connect a legacy network switch to a core switch for redundancy. The proposed cable will run in the celling above high-voltage industrial equipment and fluorescent lights. The legacy switch has 1000BASE-T ports with no expansion slots. The engineer has decided to use multimode cable to make this connection. Which of the following will be needed to connect the two switches?
A) RG-6 connectors
B) A patch panel
C) A GBIC transceiver
D) A media converter

Accepted Answer

A media converter is needed to convert the multimode fiber optic signal to the 1000BASE-T copper signal, as the legacy switch only has 1000BASE-T ports.
