300-415 · Question #375

Which two features are not supported when FIPS mode is enabled on a Cisco IOS XE SD-WAN device? (Choose two.)

The correct answer is C. Cisco TrustSec E. PAC Authentication Key. When FIPS mode is enabled on a Cisco IOS XE SD-WAN device, features like Cisco TrustSec and the use of PAC Authentication Keys are not supported due to the strict cryptographic and security requirements of FIPS.

Why each option

When FIPS mode is enabled on a Cisco IOS XE SD-WAN device, features like Cisco TrustSec and the use of PAC Authentication Keys are not supported due to the strict cryptographic and security requirements of FIPS.

ASXP reflectors

SXP reflectors, which propagate SGTs, are generally supported in FIPS mode unless they rely on a non-FIPS compliant underlying component.

BSXP over IPv6

SXP over IPv6 is a protocol transport mechanism and is not specifically disallowed by FIPS mode on SD-WAN devices.

CCisco TrustSecCorrect

Cisco TrustSec, which uses Security Group Tags (SGTs) for policy enforcement, is not supported in FIPS mode on Cisco IOS XE SD-WAN devices, as TrustSec often relies on security methods not compliant with FIPS standards.

DStatic IP-SLA mapping

Static IP-SLA mapping is a performance monitoring feature that is typically unaffected by FIPS mode enablement.

EPAC Authentication KeyCorrect

The use of PAC Authentication Keys is explicitly not supported when FIPS mode is enabled on Cisco IOS XE SD-WAN devices, as FIPS requires more stringent authentication mechanisms.
