Yelena W.Nov 2, 2025B is the right call here. A firewall is the standard control for blocking inbound network attacks because it inspects and filters traffic at the network perimeter based on rules, stopping malicious packets before they ever reach your protected endpoints, which is exactly what Carbon Black pairs with on the host side to give you layered defense.
Dervla O.Nov 4, 2025Solid reasoning, but watch your stem: if the question swaps "block" for "detect" or shifts scope from the perimeter to the host, that same layered-defense logic flips B to a distractor and puts the endpoint solution at the top of your list.
Brenda K.Oct 27, 2025Grabbed for A first, but "inbound attack protection" screams Firewall, not load distribution.
Dervla O.Oct 21, 2025Going with C on this one and here is why. Read the stem again, it says inbound network attacks, and a proxy sits between outside traffic and your internal network, inspecting and filtering requests before they ever reach your systems. That interception role is exactly what you want when the threat is coming from outside, because the proxy absorbs and evaluates the connection on behalf of the internal host. Load balancers distribute traffic, reverse proxies handle outbound-facing concerns, and firewalls work at a different layer of control, so when the stem specifically frames the attack as inbound and asks for a solution, the proxy architecture fits tightest. Eliminate what does not match the framing, and C is what stays standing.
Yelena W.Oct 24, 2025Dervla, I see where you are going with that, but B is the better fit here because a firewall is specifically designed to inspect and block inbound traffic based on rules at the network perimeter, which is the exact control the stem is pointing toward. A proxy intercepts and forwards requests on behalf of clients, which is a different function and a different trust relationship than what the question is describing.
