TheIKE (Internet Key Exchange)Phase 1 handshake error indicates a failure in negotiating a secure connection.

Option A:The IKE hashing algorithm mismatch, including key lengths, often causes such failures. Both VPN devices must agree on compatible algorithms and key lengths for the handshake to succeed.

Option B:Multiple cipher suites do not inherently cause errors; they provide flexibility during negotiation.

Option C:While using a legacy Diffie-Hellman group is less secure, it does not typically cause the handshake to fail unless explicitly rejected.

Option D:Site-to-site VPNs do not use SSL/TLS; they rely on IPSec protocols, making this irrelevant.

CompTIA CASP+ Exam Objective 2.2: Implement network security solutions, including VPN configurations.

Filter XYZ is the best option that meets the budget needs of the business. Filter XYZ has an ALE of $1 million per year, which is lower than any other filter option. ALE stands for annualized loss expectancy, which is a measure of how much money a business can expect to lose due to a risk over a year. ALE is calculated by multiplying the annualized rate of occurrence (ARO) of an event by the single loss expectancy (SLE) of an event. ARO is how often an event is expected to occur in a year. SLE is how much money an event will cost each time it occurs. Therefore, ALE = ARO x SLE. Filter XYZ has an ARO of 0.1 and an SLE of $10 million, so ALE = 0.1 x $10 million = $1 million.

Containerization separates corporate data from personal data on BYOD devices. When an employee is terminated, only the corporate container is wiped, preserving personal data. This aligns with CASP+ objective 2.4, which emphasizes securing endpoint devices while respecting privacy.
