Refer to the exhibit. A hybrid worker reports problems with video and voice performance when using the company's Webex when working from home but claims there are no issues with Webex when working…

Question

Options

• AThe worker's home router is dropping HTTPS connections.
• BWebex traffic is being routed through the VPN, which introduces unnecessary latency.
• CWebex traffic is being routed through an ISP that has connectivity drops.
• DThe worker's VPN client is periodically disconnecting from the server.

• A
  5% (2)
• B
  74% (31)
• C
  14% (6)
• D
  7% (3)

Explanation

Option B is correct because the worker's home setup routes Webex traffic through the corporate VPN, causing it to "hairpin" - traveling from home → VPN tunnel → corporate network → Webex servers - adding significant latency that degrades real-time audio and video. At the office, Webex traffic exits directly to the internet without the VPN hop, explaining why performance is fine there.

Why the distractors fail:

• A (home router dropping HTTPS): Teams also runs over HTTPS, so a router issue would affect Teams too - but Teams works fine from home, ruling this out.
• C (ISP connectivity drops): An ISP problem would impact all internet-bound traffic from home, including Teams, which has no issues.
• D (VPN disconnecting): Periodic disconnects would disrupt all VPN-dependent services equally and would show up as connection drops rather than consistent quality degradation; Teams works fine even when VPN is connected.

Memory tip: When one app has problems only at home and only over VPN, think "wrong traffic in the tunnel." The classic culprit is missing split tunneling - Webex needs to be excluded from the VPN so it routes directly to the internet instead of through the corporate hairpin.
