Cisco 300-445 (ENNA) Sample Questions:

01. Trend data over several months shows a branch's primary path is now above 85% utilization during business hours nearly every day, with steadily rising loss and latency that track the utilization curve, while an idle secondary path exists to the same destinations.
Which two recommendations does this trend most defensibly support?
(Choose two.)
a) Apply QoS to protect business-critical and real-time traffic while the capacity change is planned.
b) Disable the secondary path to simplify the branch topology and reduce ongoing management overhead.
c) Add capacity or load-balance onto the idle secondary path so demand leaves the saturated link.
d) Lower every alert threshold on the branch so that the on-call team is simply warned earlier next time.
e) Take no action, because the average utilization over the full week is still comfortably below 100%.
 
02. Users in one region report reaching a fake login page for a well-known site. Tests from that region show the hostname resolving to an IP address in an unrelated network, while BGP path visualization to the legitimate prefix looks normal and origin server throughput shows no flood.
Which security issue does this evidence point to?
a) A volumetric DDoS flood
b) BGP prefix hijacking
c) A policy-scope route leak
d) DNS hijacking
 
03. An engineer is signing off a critical rule that must page the on-call team when a payment service degrades. The engineer wants a validation approach that would catch not only a missed real event but also a spurious page and a broken delivery path.
Which approach most completely validates the rule?
a) Run a one-time simulation that shows the rule can fire, and rely on that single result as proof it works.
b) Compare the rule's configuration text against another rule that is already trusted and approve if similar.
c) Induce a controlled degradation, restore normal conditions, and review a quiet baseline period.
d) Enable the rule in production and simply wait to see whether any real incident eventually triggers it.
 
04. Capacity trend analysis for a data-center uplink shows utilization growing roughly linearly month over month, projected to reach sustained saturation in about two quarters, with no single traffic class dominating and no structural detour in the path.
What is the most defensible capacity-planning recommendation from this trend?
a) Re-architect the topology to reroute traffic, even though no detour or path inefficiency was found.
b) Wait until utilization actually reaches saturation before requesting any change, to avoid over-provisioning.
c) Apply QoS prioritization, since that alone will accommodate the continued growth indefinitely.
d) Plan and provision a capacity addition ahead of the projected saturation date.
 
05. A public service becomes intermittently unreachable. Metrics show a sudden surge in connection attempts and inbound throughput arriving from a large, geographically dispersed set of sources, with link and server capacity saturated during the surge. Name resolution and BGP paths appear unchanged.
Which security issue best matches this signature?
a) BGP hijacking of the service's prefix
b) Route leaking toward the service network
c) Distributed denial-of-service (DDoS)
d) DNS hijacking of the service's hostname
 
06. Interpreted assurance data shows that a WAN link carrying both bulk file replication and real-time voice is congested at peak, and voice quality degrades only during those peaks while the link's average utilization remains moderate.
Which optimization does the data most directly support?
a) Apply QoS so voice and other latency-sensitive traffic is serviced ahead of bulk replication.
b) Reroute all of the traffic onto a backup path regardless of that path's own available capacity.
c) Disable monitoring on the link to reduce measurement overhead during the busy peak periods.
d) Immediately double the link bandwidth, since the link is clearly fully saturated on average.
 
07. An application development team wants a deliverable that helps them decide whether a slow user experience originates in their code or in the network.
Which view best fits this audience?
a) Interface error counters aggregated per data-center switch.
b) A raw chronological feed of every alert trigger across all services.
c) Application-level timing split into components like server response and transaction stages.
d) A single executive SLA gauge summarizing monthly service availability.
 
08. Users on one campus complain that a hosted app feels slow, yet every network-path test from the campus agents to the app shows normal latency, loss, and routing.
Given the evidence, which alerting focus is most likely to surface the actual cause?
a) End-user-experience conditions such as device resource use and client connectivity type
b) Tighter thresholds on the same core-path latency alerts that already read completely normal
c) A new alert watching the application's BGP prefix reachability from upstream peers
d) An alert on the total byte volume seen in NetFlow for the campus internet uplink
 
09. A team relies on internet insights to catch provider-side problems that affect traffic reaching a SaaS application, even when their own agents look healthy.
Which condition is the most appropriate basis for an internet-insights alert?
a) A scheduled increase in the local test frequency configured on the monitoring agents
b) A detected outage or degradation on a transit provider in the path to the application
c) A cosmetic change to the wording of the application's public landing-page text
d) A single monitoring agent briefly failing one HTTP request to the application's endpoint
 
10. Traffic between two providers that normally exchange directly is observed taking a longer detour through a third transit network. The prefixes involved are still originated by their rightful owners, but a middle AS is re-advertising routes it learned from one peer to another peer against normal policy.
Which security or routing issue does this describe?
a) DNS resolution hijacking
b) A false-origin BGP hijack
c) A DDoS reflection flood
d) Route leaking
