• Question 1121:

  A hydroelectric company wants to manage sensors at a dam remotely. The control station at this dam is several miles off the main road in a densely forested area. Which of the following should the company implement to connect remotely to the sensors?

  A. Cable broadband

  B. DSL Internet

  C. Cellular modem

  D. ISDN Internet

  Correct Answer: C

• Question 1122:

  A technician is troubleshooting a client's report about poor wireless performance. Using a client monitor, the technician notes the following information:

  

  Which of the following is MOST likely the cause of the issue?

  A. Channel overlap

  B. Poor signal

  C. Incorrect power settings

  D. Wrong antenna type

  Correct Answer: A

  Channel overlap will happen here you need a gap between channels.

• Question 1123:

  Which of the following technologies provides a failover mechanism for the default gateway?

  A. FHRP

  B. LACP

  C. OSPF

  D. STP

  Correct Answer: A

  FHRP is used to prevent network failure at a default gateway. This is achieved by configuring multiple routers with the same IP address and Mac address, thus presenting an illusion of a single virtual router to the hosts in a Local Area Network (LAN).

• Question 1124:

  A company has multiple site-to-site VPN connections using a pre-shared key. The Chief Information Security Officer (CISO) is concerned about the long-term security of the tunnels and has asked the network technicians to develop a plan to ensure the best security of the tunnels. Which of the following should the network technicians implement?

  A. Purchase dedicated MPLS circuits between each of the sites.

  B. Request a change of IP addresses from the ISP semiannually.

  C. Perform annual key rotations on the site-to-site VPNs.

  D. Terminate tunnels when they are not actively being used.

  Correct Answer: C

• Question 1125:

  Which of the following is the physical topology for an Ethernet LAN?

  A. Bus

  B. Ring

  C. Mesh

  D. Star

  Correct Answer: D

  In a Star topology, all devices on the LAN are connected to a central hub or switch. The hub or switch acts as a central point for data transmission and reception. Each device on the LAN has a dedicated connection to the hub or switch, and data is transmitted between devices through the hub or switch.

• Question 1126:

  At which of the following OSI model layers does the Layer 2 Tunneling Protocol operate?

  A. Application

  B. Session

  C. Transport

  D. Data link

  Correct Answer: D

• Question 1127:

  Which of the following can be used to decrease latency during periods of high utilization of a firewall?

  A. Hot site

  B. NIC teaming

  C. HA pair

  D. VRRP

  Correct Answer: C

  An HA pair is a group of two firewalls that are configured to work together to provide high availability and failover protection. If one firewall becomes unavailable, the other firewall can take over and continue providing network services. This can help to decrease latency during periods of high utilization because the workload is distributed across two firewalls rather than being handled by a single device.

• Question 1128:

  A network technician wants to ensure the backup configuration files for the network devices are not being altered after they are stored. Which of the following tasks should the network technician perform to achieve this goal?

  A. Compute the checksum of the backup file and document it separately.

  B. Store the backup files on a thumb drive and keep it in a desk drawer.

  C. Encrypt the drive the files are stored on using AES-256.

  D. Upload the backup files to a cloud storage service.

  Correct Answer: A

• Question 1129:

  A network technician has just implemented a new wireless network that requires clients to use a WEP key for access. The technician is now required to make changes to ensure the network uses the strongest encryption available. After the changes are implemented, several users report being unable to connect. Which of the following is the MOST likely cause?

  A. RADIUS server failure

  B. Security type mismatch

  C. Wrong passphrase

  D. Incorrect SSID

  Correct Answer: B

• Question 1130:

  A network technician has been asked to provide daily reports on network saturation. Which of the following would BEST reflect these statistics?

  A. Average bandwidth usage

  B. Error rate on trunk ports

  C. Packet drops to the ISP

  D. Processor utilization for the Internet router

  Correct Answer: A
