This PCNSE practice question tests your understanding of manage, monitor and operate. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

ssl-decryption:

allow-block tls1-0
block tls1-1
allow tls1-2TLS 1.1
The profile explicitly blocks TLS 1.1.
TLS 1.0
Why wrong: TLS 1.0 is allowed with 'allow-block' (allowed but block list?)
TLS 1.3
Why wrong: TLS 1.3 is not mentioned in the profile.
TLS 1.2
Why wrong: TLS 1.2 is allowed.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
TLS 1.1
The decryption profile in the exhibit shows 'TLS 1.1' explicitly selected under 'Block SSL/TLS Versions,' meaning any session attempting to negotiate TLS 1.1 will be blocked. This is a direct configuration setting in Palo Alto Networks firewalls where you can selectively block specific SSL/TLS protocol versions to enforce stronger cryptographic standards.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
TLS 1.1
Why this is correct
The profile explicitly blocks TLS 1.1.
Related concept
Read the scenario before looking for a memorised answer.
TLS 1.0
Why it's wrong here
TLS 1.0 is allowed with 'allow-block' (allowed but block list?)
TLS 1.3
Why it's wrong here
TLS 1.3 is not mentioned in the profile.
TLS 1.2
Why it's wrong here
TLS 1.2 is allowed.
Common exam traps
Palo Alto Networks often tests the ability to read the exhibit carefully—candidates may assume that because TLS 1.1 is a deprecated protocol, the question is about which version is allowed, or they might confuse the 'Block' list with the 'Allow' list, leading them to pick TLS 1.0 or TLS 1.2 as the blocked version.
Detailed technical explanation
Palo Alto Networks decryption profiles allow granular control over SSL/TLS protocol versions by checking the 'Block SSL/TLS Versions' checkboxes; the firewall then inspects the ServerHello message during the SSL handshake and drops the session if the negotiated version matches a blocked version. This is critical in environments that must comply with PCI DSS or other standards that require disabling older, vulnerable protocols like TLS 1.0 and 1.1, while still allowing TLS 1.2 and 1.3 for secure traffic.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the PCNSE exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
