A network administrator needs to connect two routers in a point-to-point configuration and conserve IP space. Which of the following subnets should the administrator use?
Answer: D
D. /30 Explanation: A /30 subnet provides 4 IP addresses in total, with 2 usable IP addresses for hosts. This is ideal for a point-to-point link because only two IP addresses are needed (one for each router).

A network administrator wants to implement an authentication process for temporary access to an organization's network. Which of the following technologies would facilitate this process?
Answer: A
The correct answer is A: Captive portal. Captive portals are specifically designed for temporary access management. The other options are less suitable because: Enterprise authentication (B): This is more suited for permanent employees and requires complex setup Ad hoc network (C): This refers to a temporary network structure, not an authentication method WPA3 (D): This is an encryption standard for securing wireless networks, not specifically for managing temporary access

A research facility is expecting to see an exponential increase in global network traffic in the near future. The offices are equipped with 2.5Gbps fiber connections from the ISP, but the facility is currently only utilizing 1Gbps connections. Which of the following would need to be configured in order to use the ISP's connection speed?
Answer: D
A VoIP phone is plugged in to a port but cannot receive calls. Which of the following needs to be done on the port to address the issue?
Answer: C

A network manager wants to implement a SIEM system to correlate system events. Which of the following protocols should the network manager verify?
Answer: A
A. NTP Explanation: A SIEM (Security Information and Event Management) system collects and correlates logs and events from multiple devices across a network. Accurate time synchronization is crucial to ensure that logs and events from different sources are correlated correctly. NTP (Network Time Protocol) is used to synchronize the clocks of network devices, ensuring that timestamps in logs are consistent across the network.

A network engineer is designing a secure communication link between two sites. The entire data stream needs to remain confidential. Which of the following will achieve this goal?
Answer: C
C. ESP Explanation: ESP (Encapsulating Security Payload) is a protocol used in IPSec to provide confidentiality, integrity, and authentication for data transmitted over a network. ESP encrypts the entire data payload, ensuring that the data stream remains confidential. This is the most suitable option for maintaining confidentiality in a secure communication link.

Which of the following protocols has a default administrative distance value of 90?
Answer: B
B. EIGRP Explanation: EIGRP (Enhanced Interior Gateway Routing Protocol) has a default administrative distance (AD) value of 90. This value is used to determine the trustworthiness of routes learned from different routing protocols. The lower the AD, the more preferred the route.

An office is experiencing intermittent connection issues. A network engineer identifies that the issue occurs whenever someone uses the fax machine that is connected to a switch. Which of the following should the engineer do first to resolve the issue?
Answer: D
D. Configure a VLAN. Explanation: The issue described suggests that the fax machine, which is likely generating a high amount of traffic or interference, is causing disruption to other devices on the same network segment. In this case, placing the fax machine on a separate VLAN can help isolate it from other devices and prevent it from interfering with regular network traffic.
