CISCO CCNP Security Exam Logo

1 / 10

Which deployment model allows a remote user to reach an internal or SaaS application through a browser only, without installing any endpoint agent, when using a zero-trust access platform such as Cisco Secure Access?

Clientless (browser-based) zero-trust access

A dedicated leased line connecting the user's home directly to the data center

A manually configured static route entered on the user's home router

Site-to-site IPsec tunneling between two data centers with no involvement of individual end users

Client-based access, which requires an installed endpoint agent such as Cisco Secure Client

A physical hardware token issued to the user with no browser or agent involvement

2 / 10

Which scenario would most likely justify choosing client-based zero-trust access (such as via Cisco Secure Client) over clientless browser-based access for a particular use case?

Client-based access guarantees zero latency for every application regardless of network conditions

Client-based access eliminates the need for any identity authentication prior to granting access

Client-based access removes the need for any zero-trust policy enforcement entirely

Client-based access is required for absolutely every use case and clientless access is never a valid option under any circumstance, based on standard platform behavior, which is not the standard approach, under typical configuration conditions

The user needs access to non-web (such as native client-server or thick-client) applications, or the organization requires deeper endpoint posture and telemetry integration than a browser session alone can provide

Client-based access is only relevant for guest users who have no relationship with the organization

3 / 10

Which transport protocol, built on UDP and designed to reduce connection establishment latency and improve performance on lossy networks, is increasingly used by modern zero-trust access clients?

Legacy TCP with no UDP-based transport involved at all

NTP, which is a time synchronization protocol unrelated to transport-layer connection performance

FTP, which is a legacy file transfer protocol unrelated to reducing connection latency

QUIC

SNMP, which is a device management/monitoring protocol rather than a transport protocol

SMTP, which is an email transfer protocol unrelated to transport-layer connection performance

4 / 10

Which purpose does MASQUE (Multiplexed Application Substrate over QUIC Encryption) serve in the context of modern zero-trust remote access architectures?

It is a printer communication standard with no relationship to network tunneling

It is a badge access control standard used exclusively for physical building entry

It is a billing protocol used exclusively for calculating cloud subscription costs

It provides a standardized mechanism for proxying and tunneling traffic (including UDP-based traffic) over QUIC, enabling more efficient and flexible secure access connections

It is a database replication protocol with no relationship to network transport or tunneling, in accordance with common design practices, which is inconsistent with expected behavior

It is a physical networking cable standard used exclusively for data center rack cabling

5 / 10

Which benefit would an organization most likely realize by adopting QUIC- and MASQUE-based transport for its zero-trust access client connections compared to legacy TCP-based VPN tunnels?

Adopting QUIC and MASQUE is only relevant for guest users and has no bearing on employee remote access performance

Adopting QUIC and MASQUE automatically eliminates the need for any endpoint posture assessment

Adopting QUIC and MASQUE eliminates the need for any identity authentication before establishing a connection

Adopting QUIC and MASQUE requires disabling encryption entirely to achieve improved performance

Improved connection resilience and reduced latency, particularly on networks with packet loss or when users roam between networks (such as Wi-Fi to cellular)

Adopting QUIC and MASQUE guarantees that no security policy enforcement is ever required on the resulting connection, in most deployment scenarios, which is not the standard approach

6 / 10

Which zero-trust access design would provide appropriate access for a mix of managed corporate laptops (needing full application suite access) and unmanaged contractor devices (needing limited web-application access only)?

Clientless browser-based access with unrestricted application scope for both managed corporate laptops and unmanaged contractor devices equally

Denying all access entirely to both managed corporate laptops and unmanaged contractor devices under any circumstance

Client-based access with full posture assessment for both managed corporate laptops and unmanaged contractor devices equally

Requiring unmanaged contractor devices to install the same full endpoint agent required for managed corporate laptops

Granting unmanaged contractor devices the exact same access scope as managed corporate laptops with no distinction at all

Client-based access with full posture assessment for managed corporate laptops, and clientless browser-based access scoped to specific approved web applications for unmanaged contractor devices

7 / 10

Which factor would most influence whether an organization chooses clientless or client-based zero-trust access for a particular remote work scenario?

The specific brand of coffee served in the organization's network operations center

The color scheme configured for the zero-trust access platform's administrative dashboard, in a properly maintained environment, based on standard platform behavior, in most deployment scenarios

The average outdoor temperature at the organization's headquarters

The type of application being accessed (web-based versus native/thick-client) and the level of endpoint trust and posture visibility the organization requires for that scenario

The number of parking spaces available at the organization's headquarters

The font used in the organization's internal newsletter

8 / 10

Which troubleshooting step would be appropriate if a remote user's zero-trust access client (using QUIC/MASQUE transport) is failing to establish a connection while users on legacy TCP-based tunnels are unaffected?

Assume QUIC and MASQUE are deprecated protocols no longer supported by any zero-trust access platform

Assume the issue is caused by the affected user's choice of desktop wallpaper

Assume the issue is unrelated to transport protocol and only check the user's monitor resolution settings

Immediately replace the user's endpoint device entirely as the first troubleshooting step

Check whether the user's network path (such as a restrictive firewall or captive portal) is blocking outbound UDP traffic required by QUIC, since some network environments restrict UDP more aggressively than TCP

Assume the issue is caused by the phase of the moon

9 / 10

Which statement accurately describes why zero-trust access platforms increasingly support both clientless and client-based access models rather than standardizing on only one?

Supporting both models eliminates the need for any identity authentication for either access type

Clientless access is being fully deprecated in favor of client-based access for every use case without exception

Different use cases (unmanaged contractor or partner devices needing scoped web access versus managed corporate devices needing full application access with deep posture checks) require different levels of access breadth and endpoint trust, which a single model cannot address equally well

Client-based access is being fully deprecated in favor of clientless access for every use case without exception

Clientless and client-based access are simply two different names for the exact same identical access model with no distinction, which does not align with best practices, under normal operating conditions, in most deployment scenarios, in accordance with common design practices, though this is not generally recommended

Supporting both models exists purely for marketing purposes and provides no actual functional benefit to the organization

10 / 10

Which combination of zero-trust remote access design choices would provide secure, performant access for a globally distributed workforce using a mix of managed and unmanaged devices accessing both web and native applications?

Client-based access with full posture assessment and QUIC/MASQUE transport for managed devices needing native application access, clientless scoped browser access for unmanaged devices needing only web applications, and policy enforcement consistent across both models

Granting unmanaged devices full native application access identical to managed corporate devices

Disabling posture assessment entirely for managed devices to simplify the access experience

Requiring every device, managed or unmanaged, to use client-based access with no clientless option available at all, in accordance with common design practices, which is not the standard approach, which does not align with best practices, which is inconsistent with expected behavior

Using only legacy TCP-based tunnels for all users regardless of network conditions or roaming needs

Applying policy enforcement only to managed devices while leaving unmanaged devices entirely unrestricted
