A network administrator configures a router with the following IP address information:
Gigabit Ethernet 1 Interface: 10.10.0.1/24
Serial 0 Interface: 10.10.0.253/30
Clients are connected to a switch on the gigabit Ethernet interface; the ISP is connected to the Serial 0 interface. When
the router configuration is complete and client devices are reconfigured, all clients report that they are unable to connect
to the Internet. Which of the following is the MOST likely reason?
A. The router was configured with an incorrect IP address
B. The router was configured with an incorrect default gateway
C. The router was configured with an incorrect subnet mask
D. The router was configured with an incorrect loopback address
C. The router was configured with an incorrect subnet mask

B. Octal
C. Binary
D. CIDR
A. Hex
Users are reporting issues with slow connection speeds and a loss of connectivity on the newly installed wireless
network. The issues are intermittent but seem to occur most often around midday. Which of the following is the MOST
likely cause?
A. There is interference from small appliances
B. The signal coverage area is too small
C. Not enough DHCP addresses have been allotted
D. The DNS cache on the users’ computers has become corrupt
C. Not enough DHCP addresses have been allotted
When choosing a type of storage that integrates with the existing network infrastructure, the storage must be easily
configurable to share files and can communicate with all existing clients over TCP/IP. Which of the following is the
BEST technology for the network administrator to implement?
A. iSCSI
B. Fibre Channel
C. NAS
D. DAS
C. NAS
A building is equipped with light sensors that turn off the fluorescent lights when natural light is above acertain
brightness. Users report experiencing network connection issues only during certain hours. The west side of the building
experiences connectivity issues in the morning hours and the east side near the end of the day. At night the connectivity
issues affect the entire building. Which of the following could be the cause of theconnectivity issues?
A. Light sensors are interfering with the network
B. EMI from the lights is interfering with the network cables
C. Network wiring is run perpendicular to electrical conduit
D. Temperature changes are causing attenuation in copper cabling
C. Network wiring is run perpendicular to electrical conduit
A contractor is setting up and configuring conference rooms for a convention. The contractor sets up each room in the
conference center to allow wired Internet access going to individual tables. The contractor measured the distance
between the hotel’s patch panel to the jack, and the distance is within Cat 5e specifications. The contractor is concerned
that the room will be out of specification if cables are run in each room from the wall jacks. Which of the following
actions should the contractor take to ensure the cable runs meet specifications and the network functions properly?
A. Place a switch at the hotel’s patch panel for connecting each room’s cables
B. Place a switch on each table to ensure strong connectivity
C. Place repeaters between the patch panel and the rooms
D. place a switch at the wall jack and run the cables in the room from there
A. Place a switch at the hotel’s patch panel for connecting each room’s cables

B. Vulnerability scan
C. System life-cycle report
D. Archiving logs
A. Baseline review
A network administrator has a monitoring system in place that is currently polling hundreds of network devices at
regular intervals. The continuous polling is causing high CPU utilization on the server. Which of the following tasks
should the administrator perform to resolve the CPU issue while maintaining full monitoring capabilities?
A. Remove SNMP polling and configure SNMP traps on each network device
B. Remove SNMP polling and implement snmpwalk on each network device
C. Upgrade SNMP to the latest version to mitigate vulnerabilities
D. Modify SNMP polling to poll only during business hours
A. Remove SNMP polling and configure SNMP traps on each network device
