Which Two Devices Support WCCP for Traffic Redirection?
Short answer
BE The Cisco Secure Web Appliance and the Cisco ASA are the two listed devices that support WCCP for traffic redirection.
Question
Key Takeaways
This item tests whether you can separate a WCCP-capable appliance from a platform/OS name, and the trap is reading "Cisco IOS" — an operating system, not a device — as a valid redirection device when the stem explicitly asks for devices.
WCCP traffic redirection transparently sends web requests to a caching or proxy appliance, and this SCOR question asks which two listed devices actually support it. The answer is the Cisco Secure Web Appliance and the Cisco ASA (B, E), not the Cisco IOS operating system.
Common mistake: Picking Cisco IOS (A) because IOS routers are the textbook WCCP redirector; the option names an operating system rather than a device, so it fails the stem's "devices" wording — which is exactly why a quarter of the community split toward A, E instead of B, E.
Expert Analysis
Why the Answer Is Correct
WCCP (Web Cache Communication Protocol) exists to transparently redirect HTTP/HTTPS sessions from a redirecting device to a cache engine, and the two Cisco hardware appliances on this list are the Cisco Secure Web Appliance and the Cisco ASA. The Secure Web Appliance is documented as a WCCP-enabled content appliance that joins a WCCP service group and receives redirected web traffic, and the ASA is documented as a WCCP-capable redirector that can steer intercepted sessions to that appliance without a separate router. Both options therefore satisfy the literal stem — "devices" that "support WCCP for traffic redirection" — while "Cisco IOS" names an operating system rather than a physical appliance. The community reflects this reading: klu16 wrote "Cisco IOS is not a device. It's an operating system.", and the vote distribution leans 75% toward B, E.
Why the Other Options Are Wrong
Option A (Cisco IOS) is the strongest distractor because IOS-based routers and switches do run WCCP services, but the option is a software platform name, not a device, so it does not answer a question phrased around devices. Option C (Cisco IPS) is an inline intrusion prevention sensor that inspects and drops malicious traffic; it does not host WCCP service groups and cannot redirect sessions to a cache engine. Option D (proxy server) is a generic endpoint description rather than a Cisco WCCP-capable appliance, and WCCP is a Cisco-defined protocol implemented on IOS, ASA and the Secure Web Appliance. The A/E combination argued by aa4a63c — IOS routers plus ASA firewalls — is the classic redirector pairing in real deployments, but it overlooks that the exam asks about devices and lists IOS as an OS.
Community Comment Notes
klu16 makes the decisive point with the verbatim remark "Cisco IOS is not a device. It's an operating system.", which is precisely the wording trap the question sets. aa4a63c reasons the other way, listing IOS routers and ASA firewalls as the devices that redirect traffic, which explains why the A, E option still collects roughly a quarter of the votes. kloug simply recorded "A,e answer" without further justification, showing how many learners default to the router-plus-firewall mental model instead of reading the stem literally.
Exam Strategy
Read the noun the stem asks for before evaluating technology: here it is "devices", so a software platform name such as Cisco IOS is disqualified even though IOS routers do run WCCP. Then recall the standard WCCP deployment pair — a redirecting appliance and a cache engine — and match it to the appliance options rather than the OS or sensor options.

aa4a63c 👍 1Devices Supporting WCCP: Cisco IOS Routers: Cisco IOS routers are a primary device that supports WCCP for traffic redirection. Cisco ASA Firewalls: Cisco ASA firewalls also support WCCP, allowing them to redirect traffic to WCCP-capable devices.
