A network administrator is configuring a wireless connection between two warehouses. Which of the following wireless network types would best accomplish this task?
A. Ad hoc
B. Infrastructure
C. Point-to-point
D. Mesh
Show Answer
Correct Answer: C
Explanation: A point-to-point wireless link is designed to connect two fixed locations, such as separate warehouses, using directional antennas to form a dedicated bridge. Ad hoc connects clients directly, infrastructure uses access points for client access within a WLAN, and mesh is intended for multi-node resilient coverage rather than a dedicated building-to-building link.
Question 128
A network architect is implementing a VPN solution for remote workers. The architect wants to ensure that data transmitted through the VPN is protected from eavesdropping and tampering. Which of the following solutions meet these requirements? (Choose two.)
A. SSL
B. AES
C. TKIP
D. IPSec
E. EAP
F. SSH
Show Answer
Correct Answer: A, D
Explanation: SSL/TLS VPNs and IPsec VPNs can both encrypt traffic to prevent eavesdropping and verify its integrity to detect tampering. AES is an encryption algorithm, not a complete VPN solution or an integrity mechanism on its own.

Question 128
A network technician is requesting a fiber patch cord with a connector that is round and twists to install. Which of the following is the proper name of this connector type?
A. ST
B. BNC
C. SC
D. LC
Show Answer
Correct Answer: A
Explanation: The ST (Straight Tip) fiber connector has a round body and uses a bayonet-style twist-lock mechanism to install. SC and LC are push-pull fiber connectors, while BNC is a bayonet connector used for coaxial cable rather than fiber.
Question 129
Which of the following is associated with avoidance, acceptance, mitigation, and transfer?
A. Risk
B. Exploit
C. Threat
D. Vulnerability
Show Answer
Correct Answer: A
Explanation: Avoidance, acceptance, mitigation, and transfer are the standard risk treatment (risk response) strategies used in risk management. They describe how an organization chooses to handle identified risks, not threats, vulnerabilities, or exploit actions.
Question 129
Which of the following actions should be taken as part of the first step of the troubleshooting methodology?
A. Conduct tests to verify ideas.
B. Handle multiple problems individually.
C. Create a theory about the possible root cause.
D. Use a top-down approach.
Show Answer
Correct Answer: B
Explanation: The first troubleshooting step is to identify the problem, which includes separating multiple issues and handling them one at a time. Creating a theory is step 2, and testing it is step 3. A top-down approach is a method used when establishing a theory of probable cause.
Question 130
After a networking intern plugged in a switch, a significant number of the users in a building lost connectivity. Which of the following is the most likely root cause?
A. VTP update
B. Port security issue
C. LLDP misconfiguration
D. Native VLAN mismatch
Show Answer
Correct Answer: A
Explanation: A VTP update is the most likely cause. If the newly connected switch participates in the same VTP domain and has a higher configuration revision, it can propagate an incorrect VLAN database to other switches, disrupting connectivity for many users. Port security and LLDP issues are typically more localized; a native VLAN mismatch generally affects traffic on the mismatched trunk.
Question 130
A technician is designing a cloud service solution that will accommodate the company's current size, compute capacity, and storage capacity. Which of the following cloud deployment models will fulfill these requirements?
A. SaaS
B. PaaS
C. IaaS
D. IaC
Show Answer
Correct Answer: C
Explanation: IaaS (Infrastructure as a Service) provides scalable virtualized compute, storage, and networking resources, allowing an organization to size infrastructure to its current needs while expanding later. SaaS delivers finished software, PaaS provides an application development platform, and IaC is an automation approach rather than a cloud deployment/service model.
Question 131
Which of the following can be implemented to add an additional layer of security between a corporate network and network management interfaces?
A. Jump box
B. Console server
C. API interface
D. In-band management
Show Answer
Correct Answer: A
Explanation: A jump box acts as a controlled intermediary between the corporate network and network management interfaces. Administrators connect to it first, allowing access controls, authentication, and monitoring to be enforced before they reach managed devices.
Question 131
Which of the following is concerned with guaranteed availability of a cloud resource?
A. IPAM
B. SLA
C. MTBF
D. EOL
Show Answer
Correct Answer: B
Explanation: An SLA (Service Level Agreement) defines the agreed service levels between a cloud provider and customer, including guaranteed availability or uptime targets and remedies if those targets are not met. IPAM manages IP addresses, MTBF is a reliability metric rather than a contractual guarantee, and EOL refers to the end of a product's supported lifecycle.
Question 132
A company’s network is experiencing high latency and packet loss during peak hours. Network monitoring tools show increased traffic on a switch. Which of the following should a network technician implement to reduce the network congestion and improve performance?
A. Load balancing
B. Port mirroring
C. Quality of service
D. Spanning Tree Protocol
Show Answer
Correct Answer: C
Explanation: Quality of service (QoS) can manage and prioritize traffic on a congested switch, helping reduce latency and packet loss for important traffic during peak hours. Load balancing would require alternative paths or resources, which the question does not identify.
