A. Change the access point from WPA2 to WEP to determine if the encryption is too strong
B. Clear all access logs from the AP to provide an up-to-date access list of connected users
C. Check the MAC address of the AP to which the users are connecting to determine if it is an imposter
D. Reconfigure the access point so that it is blocking all inbound and outbound traffic as a troubleshooting gap

A new virtual server was created for the marketing department. The server was installed on an existing host machine. Users in the marketing department report that they are unable to connect to the server. Technicians verify that the server has an IP address in the same VLAN as the marketing department users. Which of the following is the MOST likely reason the users are unable to connect to the server?
A. The new virtual server’s MAC address was not added to the ACL on the switch
B. The new virtual server’s MAC address triggered a port security violation on the switch
C. The new virtual server’s MAC address triggered an implicit deny in the switch
D. The new virtual server’s MAC address was not added to the firewall rules on the switch
A network technician is attempting to connect a new host to existing manufacturing equipment on an Ethernet network. The technician is having issues trying to establish communication between the old equipment and the new host. The technician checks the cabling for breaks and finds that the CAT3 cable in use is in perfect condition. Which of the following should the technician check to ensure the new host will connect?
A. Confirm the new host is using 10GBaseSR due to the manufacturing environment
B. Confirm the new host is compatible with 10BaseT Ethernet
C. Confirm the existing 10Base2 equipment is using the proper frame type
D. Confirm that CSMA/CD is disabled on the Ethernet network
A network administrator is noticing slow responds times from the server to hosts on the network. After adding several new hosts, the administrator realizes that CSMA/CD results in network slowness due to congestion at the server NIC. Which of the following should the network administrator do to correct the issue?
A. Add a honeypot to reduce traffic to the server
B. Update the Ethernet drivers to use 802.3
C. Add additional network cards to the server
D. Disable CSMA/CD on the network
A network administrator is using a packet analyzer to determine an issue on the local LAN. Two separate computers are showing an error message on the screen and are unable to communicate with other computers in the same lab. The network administrator looks at the following output:
SRC MAC SRC IP DST MAC DST IP
00:1D:1F:AB:10:7D192.168.1.10:200015:BE:9F:AB:10:1D192.168.1.14:1200

Given that all the computers in the lab are directly connected to the same switch, and are not using any virtualization technology, at which of the following layers of the OSI model is the problem occurring?
A. Network
B. Application
C. Data link
D. Transport
Users have reported poor network performance. A technician suspects a user may have maliciously flooded the network with ping request. Which of the following should the technician implement to avoid potential occurrences from happening in the future?
