ZPX here means Zscaler Private Service Edge (PSE) for ZIA and ZPA — the on-prem / customer-hosted edge when public Service Edge is not allowed or not close enough.

• When you need ZPX / PSE vs Public Service Edge (sovereignty, latency, air-gap, partner DC)
• ZIA Private Service Edge vs ZPA Private Service Edge — different job, same family
• Sizing, HA pair, management plane, certificates, NTP, DNS
• Traffic path: user / GRE / ZCC → ZPX → internet or App Connector
• Scenario A: ZPX registered but 0 traffic — check enrollment, firewall to Zscaler cloud, time skew, provisioning key
• Scenario B: Users still hit Public SE — location forwarding / PAC / ZCC forwarding profile still points to cloud VIP
• Scenario C: One node in HA is “up” but sessions drop on failover — state, VIP, return path
• Proof: enrollment status, health, session count, next hop. Isolate first. Do not rebuild the pair on a P1.

• What Branch Connector is: small-site forwarding for ZIA / ZPA without a full GRE router project
• When Branch Connector vs GRE/IPSec vs ZCC-only roaming
• Form factors: VM (VMware / Hyper-V / KVM), hardware appliance, cloud image where licensed
• Deployment method: provision in Admin → download image / ISO → bootstrap key → WAN + LAN + management
• Install walkthrough: IP, default route, DNS, NTP, enroll, register location, health
• HA / dual WAN notes and what “green” does not prove
• Scenario: Branch enrolled, users have internet but no ZIA policy — traffic not steered; check LAN default gateway, DHCP option, bypass list
• Scenario: Branch Connector up, ZPA apps dead — App Connector path vs Branch Connector path, not “ZPA is down”
• Official: help.zscaler.com Branch Connector / Cloud & Branch Connector guides (confirm current wizard on your train)

• What Cloud Connector is: workload / VPC-VNet traffic into ZIA or ZPA without hairpinning users
• Cloud Connector vs App Connector vs Branch Connector — one sentence each
• Deploy method: Marketplace / Terraform / CloudFormation / ARM — VPC, subnets, route tables, IAM, bootstrap
• Install: pair, group, provisioning URL, health, route 0/0 or selected prefixes
• Workload identity vs user identity — do not mix the ticket
• Scenario: EC2 cannot reach SaaS after Cloud Connector — route table still points at IGW or NAT
• Scenario: Cloud Connector healthy, one subnet bypassed — missing association, not a ZIA policy miss
• Scenario: Asymmetric return after inspect — SNAT / return path on the cloud firewall

• Install: Windows MSI / Mac PKG, IdP enroll, device posture, GPO / Intune / Jamf
• Z-Tunnel 1.0 vs 2.0, Trusted Network, forwarding profile, anti-tampering
• First proof: enrolled user, tunnel up, correct PAC/forwarding, IdP session
• Scenario: Install succeeds, tunnel never up — service not running, filter driver, VPN conflict, time, cert
• Scenario: Tunnel up, no ZIA logs — Trusted Network true, or app bypass, or wrong forwarding profile
• Scenario: ZPA tile works, internet fails (or reverse) — ZIA vs ZPA module, not “reinstall ZCC”
• Scenario: One user after Windows update — driver / WFP, collect ZCC logs, do not blast uninstall to the org
• Collect: ZCC support tool, device posture, last enroll time, next hop. Change-control before reinstall.

• Never start with “disable Zscaler.” Start with: who, which app, wired/Wi-Fi, ZCC or GRE, one user vs site vs org
• ZDX first: device CPU/Wi-Fi, last-mile ISP, Zscaler cloud hop, SaaS hop
• ZIA: inspect vs bypass, bandwidth control, poor DC choice, MTU on GRE
• ZPA: App Connector CPU, path to app, DNS inside the segment, one connector vs group
• ZCC: Tunnel 2.0 vs 1.0, split vs full, AV conflict
• Scenario: One user Teams slow, site is fine — Wi-Fi / device / ZDX score, not a new GRE
• Scenario: Whole branch slow after GRE — MTU 1400/1476, DF bit, MSS clamp
• Scenario: One SaaS slow after SSL inspect — exemption test on pilot, then inspect-exception with owner
• Success = ZDX before/after + one log field, not “user said better”

This module is a live call pattern. You stay on the phone. You do not guess. Dummy tickets in class; same order in production.

• Open: “Share your ZCC icon colour, logged-in user, and the exact URL / app name.”
• ZIA live: Policy Insight / Web Insights for that user + URL → action, rule, location. Then SSL, then PAC.
• ZPA live: Diagnostics — user, application segment, connector health, last error. Then DNS on the connector LAN.
• ZDX live: User score, hop where delay sits (device / Wi-Fi / ISP / Zscaler / app). Quote the hop, not a feeling.
• Ticket 1: “Outlook web spins.” — ZIA allow + SSL + ZDX hop
• Ticket 2: “SAP on ZPA says cannot connect.” — segment, port, connector, not ZCC reinstall
• Ticket 3: “Everything is slow since morning.” — one user vs site vs cloud; ZDX + tunnel stats
• Close sentence: what you proved, what you did not change, next window if a change is needed

• Every answer has: one sentence, then evidence, then trap
• L1 = what is it. L2 = path. L3 = last ticket you closed
• Practice the bank below out loud. Then use the free hub: /zscaler-interview-hub

Direct: ZIA inspects internet and SaaS. ZPA connects a user to a private app without a VPN. ZDX tells you where the session is slow.

Evidence: ZIA Web Insights vs ZPA Diagnostics vs ZDX hop chart.

Weak: “All Zscaler products.” Strong: name the ticket type first.

Direct: Web Insights for that user + URL. Read action, rule, SSL, location. Do not add an allow first.

Trap: If IdP / ACS is forced through a broken tunnel, you get a login loop — exempt IdP first.

Direct: Green ZCC is not an app path. Check application segment (FQDN + port), connector group health, DNS from the connector LAN, access policy.

Trap: Reinstalling ZCC does not fix a dead App Connector.

Direct: A customer-hosted Service Edge when public Zscaler edges are not allowed or not close. It still talks to Zscaler control plane. It is not an App Connector and not a Branch Connector.

Trap: “We built ZPX” is not proof users use it — check forwarding / location.

Direct: App Connector publishes private apps for ZPA. Branch Connector steers a small site into ZIA/ZPA. Cloud Connector steers cloud VPC/VNet workloads. Three jobs. One ticket must name one.

Direct: MSI/PKG → enroll to IdP → tunnel up → user visible in Admin → one ZIA log or one ZPA diagnose for a test URL/app.

Trap: Installed ≠ enrolled ≠ tunneled ≠ policy hit.

Direct: No. Scope: one user, one site, or whole org. Open ZDX. Name the hop (Wi-Fi, ISP, Zscaler, app). Then GRE MTU, inspect, or connector CPU.

Weak: “Turn off ZCC.” Strong: “ZDX shows 180 ms on last-mile, not on Zscaler.”

Direct: Ask for the exact URL. In Insights filter user + URL + last 15 minutes. Read the rule. If SSL error, check inspect vs exemption. Tell the user what you saw before you change anything.

Direct: GRE/IPSec for a site with a router and many users. ZCC for roaming laptops. Branch Connector when the site has no good GRE path and you still need a location.

Direct: IdP and ACS must not hairpin through a broken ZIA path. Exempt IdP. Prove one successful SAML in logs. Then put the rest of SaaS back on inspect.

No. We start from foundation — Zero Trust concepts, ZIA architecture — and build up to advanced deployment and troubleshooting.

You get read-only walkthroughs of a real Zscaler tenant plus recorded admin demos covering every config you would touch in production. Vendor lab licensing does not allow student write access.

Yes. Module 14 is fully focused on the ZDTA blueprint and ZIA / ZPA Admin specialization tracks.
