1Which Horizon 8 component brokers user connections, performs authentication, and entitles users to desktop pools?

A.Horizon Agent

B.Horizon Connection Server

C.Unified Access Gateway

D.Horizon Console

Explanation: The Horizon Connection Server is the broker for the entire Horizon environment. It authenticates users against Active Directory, evaluates entitlements, and brokers Blast/PCoIP/RDP sessions to the correct desktop or RDS host. Replicas share state through a JMS bus and embedded VMware Directory Service (LDAP).

2In a Horizon 8 deployment, which component is typically deployed in the DMZ to provide secure external access to internal desktops?

A.Horizon Connection Server

B.Unified Access Gateway (UAG)

C.App Volumes Manager

D.Dynamic Environment Manager

Explanation: Unified Access Gateway (UAG) is purpose-built as a hardened edge appliance for the DMZ. It terminates Blast Secure Gateway, Horizon Tunnel, and (legacy) PCoIP Secure Gateway connections, then forwards authenticated traffic to internal Connection Servers. VMware/Broadcom explicitly do not support placing Connection Servers in the DMZ.

3Which display protocol is the primary, recommended protocol for Horizon 8.x sessions?

A.PCoIP

B.RDP

C.Blast Extreme

D.ICA/HDX

Explanation: Blast Extreme is the primary, VMware-developed protocol for Horizon 8. It uses H.264/H.265/AV1 codecs, supports TCP and UDP transports, and underpins Blast Extreme Adaptive Transport (BEAT) for poor networks. PCoIP is largely deprecated in modern Horizon and Teradici has limited investment; RDP is a fallback inside the data center; ICA/HDX is Citrix's protocol, not VMware's.

4What is the function of Blast Extreme Adaptive Transport (BEAT) in Horizon 8?

A.Encrypts session data with FIPS 140-2 ciphers

B.Optimizes Blast over high-latency or lossy networks using UDP

C.Provides the embedded LDAP for Connection Server replicas

D.Captures and packages applications for App Volumes

Explanation: BEAT is a UDP-based transport mode for Blast Extreme designed to deliver acceptable user experience on high-latency, high-loss WAN links. It dynamically adapts to changing network conditions and falls back to TCP when UDP is blocked. It is enabled per pool/global Blast settings.

5Which Horizon component is installed inside the desktop or RDS host operating system to register the workload with Connection Server?

A.Horizon Client

B.Horizon Agent

C.Horizon Console

D.Horizon Help Desk Tool

Explanation: Horizon Agent runs inside the Windows or Linux guest OS of every managed desktop and RDS host. It registers the VM with Connection Server, advertises capabilities (Blast, App Volumes, DEM, smart card, USB redirection), and accepts the brokered connection.

6Which Horizon 8 feature delivers a clientless, browser-based session over HTTPS?

A.Horizon Client for Windows

B.HTML Access

C.Horizon Help Desk Tool

D.Workspace ONE Tunnel

Explanation: HTML Access (formerly Blast HTML Access) delivers Horizon desktops and apps to any HTML5-capable browser without installing the native Horizon Client. It uses Blast Extreme over HTTPS/WebSocket and is a built-in capability when the HTML Access feature is installed on the agent and the Blast Secure Gateway is enabled on UAG or Connection Server.

7Which authentication method allows Horizon users to launch Windows desktops without entering AD credentials again after they have authenticated to the broker?

A.RADIUS one-time passcodes

B.Smart card pass-through

C.True SSO

D.Anonymous logon

Explanation: True SSO uses VMware Enrollment Server with Active Directory Certificate Services to issue short-lived user certificates after federated SAML authentication (typically through Workspace ONE Access). The Horizon Agent then logs the user into Windows with that certificate, eliminating the AD password prompt entirely.

8Which protocol is used between Horizon Connection Server replicas in a pod to share configuration and session state?

A.RDP

B.JMS over TCP 4002/4101 with embedded VMware Directory Service

C.SAML 2.0

D.SMB 3.x

Explanation: Horizon Connection Servers in the same pod use a Java Message Service (JMS) bus on TCP 4002/4101 plus an embedded LDAP-compatible directory (VMware Directory Service / AD LDS) to replicate configuration and broker state. Pods are joined into Cloud Pod Architecture using a separate VIPA federation channel.

9What is the maximum supported number of Connection Servers per Horizon pod?

A.3

B.5

C.7

D.15

Explanation: A single Horizon pod supports up to 7 Connection Servers (one Standard plus six Replicas) under VMware/Broadcom configuration maximums. To scale beyond a single pod, multiple pods are federated using Cloud Pod Architecture (CPA), which currently supports up to 15 pods.

10Which two Horizon Agent features support redirection of locally connected USB devices into the remote desktop session? (Choose the most accurate answer.)

A.USB Redirection and Real-Time Audio-Video

B.ThinApp Streaming and PCoIP

C.Skyline Health and Workspace ONE

D.RDS Host Profile and Smart Policies

Explanation: USB Redirection forwards arbitrary USB devices into the Horizon session, while Real-Time Audio-Video (RTAV) handles webcams and microphones efficiently for unified communications. Both are installed as Horizon Agent options and can be controlled by Smart Policies and group policy.

VMware Horizon 8.x Professional Study Tips from Top Performers

1Get hands-on with instant clones end-to-end: golden image preparation, OS Optimization Tool, snapshot, instant-clone domain admin, and elastic provisioning.

2Master the App Volumes 4.x model: Packages (formerly AppStacks), Writable Volumes, Markers, Attachments, and how application capture differs from a real install.

3Memorize the Horizon upgrade order: Connection Server (and replicas) first, then App Volumes Manager, then UAG, then Horizon Agents on golden images, then Horizon Client.

4Drill UAG configuration: Blast Secure Gateway, PCoIP Secure Gateway (legacy), Horizon Tunnel, certificates, edge service settings, and high-availability load balancing.

5Know the auth stack cold: True SSO with VMware Enrollment Server and AD CS, SAML via Workspace ONE Access, RADIUS for MFA, and smart card pass-through.
