300-445: Designing and Implementing Enterprise Network Assurance

An engineer receives a user report that an internal website at http://test-ipv6.com is slow. Drag the HTTP Server test phases onto the steps in order to troubleshoot the issue from the Cisco ThousandEyes test view. Not all options are used. <DragDrop items={["HTTP","Connect","DNS","TLS 1.3","SSL"]} slots={[{"answer":"DNS","id":"step1","label":"step 1"},{"answer":"Connect","id":"step2","label":"step 2"},{"answer":"HTTP","id":"step3","label":"step 3"}]} explanation={"An HTTP server test first resolves the hostname through DNS, then establishes a TCP connection to the resolved server, and finally sends and receives the HTTP request. SSL/TLS negotiation is not performed because the target URL uses `http://`, not HTTPS."} reuse={false} />

An engineer is deploying a multitest template for end users. Requirements include establishing a single TCP session from the Cisco ThousandEyes Endpoint Agent to the target, testing secure authentication, and TCP path trace. Drag the options at the bottom to the boxes in the test configuration template. <DragDrop items={["SaaS - Scheduled - Network","SaaS - Scheduled - HTTP Server","NTLM","Prefer SACK","Prefer TCP (ICMP) Fallback"]} slots={[{"answer":"SaaS - Scheduled - Network","id":"global_settings_1","group":"Global Settings"},{"answer":"SaaS - Scheduled - HTTP Server","id":"global_settings_2","group":"Global Settings"},{"answer":"Prefer TCP (ICMP) Fallback","id":"protocol","label":"Protocol","group":"NETWORK"},{"answer":"Prefer SACK","id":"probing_mode","label":"Probing Mode","group":"NETWORK"},{"answer":"NTLM","id":"scheme","label":"Scheme","group":"HTTP AUTHENTICATION"}]} explanation={"A scheduled Network test supplies the network measurement configuration, while a scheduled HTTP Server test provides HTTP authentication settings. TCP with Prefer SACK performs efficient measurements using one TCP connection; Prefer TCP (ICMP) Fallback preserves TCP as the preferred protocol. In-session path tracing runs within the established TCP session. NTLM is the selected HTTP authentication scheme.\n\n**Learn more:** [Network Tests](https://docs.thousandeyes.com/product-documentation/tests/network-tests) · [HTTP Server Tests](https://docs.thousandeyes.com/product-documentation/tests/http-server-tests)"} reuse={false} />

Refer to the exhibit. A hybrid worker reports video and voice performance problems with the company’s Webex while working from home, but says Webex has no issues when used from the office. The worker also says Microsoft Teams has no problems when meeting with the company’s customers, regardless of the worker’s location. An engineer investigates the worker’s connectivity. Which issue does the engineer identify?
