Answer: D
A network engineer needs to virtualize network services, including a router, at a remote branch location. Which of the following solutions meets the requirements?
Answer: A
NFV is a technology that virtualizes network services, such as routers, firewalls, load balancers, and more, by running them as software on standard hardware rather than dedicated physical devices. This is ideal for a network engineer looking to virtualize a router and other network functions at a remote branch, as it provides flexibility, scalability, and cost-efficiency. NFV can replace physical routers with virtual router instances, meeting the stated requirements.

A network administrator has been monitoring the company’s servers to ensure that they are available. Which of the following should the administrator use for this task?
Answer: C
SNMP traps allow network devices to send alerts to a management system when specific events occur ex: high CPU usage, network outages, or hardware failures. Packet capture : Incorrect. Packet capturing (Wireshark) is used for network traffic analysis, troubleshooting, and security investigations. Data usage reports: Incorrect. This tracks network bandwidth consumption Configuration monitoring This ensures that devices comply with policies and standards but does not actively track availability or performance.

A network engineer is completing a wireless installation in a new building. A requirement is that all clients be able to automatically connect to the fastest supported network. Which of the following best supports this requirement?
Answer: A
Band steering helps clients connect to the fastest available network by encouraging capable devices to use the 5GHz band instead of the 2.4GHz band. All other options would be counter to the requirement of the fastest possible way

A company implements a video streaming solution that will play on all computers that have joined a particular group, but router ACLs are blocking the traffic. Which of the following is the most appropriate IP address that will be allowed in the ACL?
Answer: C
224.0.0.1 is a multicast IP address within the range 224.0.0.0–239.255.255.255, reserved for multicast traffic. Specifically, 224.0.0.1 is the "all hosts" multicast address, meaning it targets all devices on the local network segment that are configured to listen to multicast traffic. This aligns well with a video streaming solution for a group of computers, as multicast is commonly used for such purposes

Which of the following are the best device-hardening techniques for network security? (Choose two.)
Answer: AE
Direct device-hardening techniques (modifying the device itself): A (disabling unused ports), E (changing default passwords), stand out. Network-wide or monitoring practices: B (scanning) and C (log monitoring) are more about ongoing security management, not hardening the device. D (SSO) is about authentication, not device configuration F (least privilege on the device) may be a good choice too but. The best device-hardening techniques from the list are A and E, as they are universally recognized, directly applicable to securing the device, and foundational to reducing vulnerabilities.
