Which two factors present a risk to the availability of the CGE environment based on the current provision for external access to it? (Choose two.)

Single-factor authentication is a security vulnerability, increasing the risk of unauthorized access, but it does not inherently prevent the system from being available to legitimate users.

A single Secure Gateway server represents a single point of failure; its outage would prevent external access for users in that location, directly impacting availability.

Using NetScaler Gateway to load balance StoreFront enhances availability by distributing traffic and providing redundancy for StoreFront services, rather than posing a risk.

The absence of automatic failover between regions means that if one entire region becomes unavailable, end users cannot seamlessly connect to another functional region, leading to service disruption and reduced availability.
