To ensure that clients checking in every 10 days receive xdelta content packages instead of full content packages, 30 content revisions must be retained on the Symantec Endpoint Protection Manager (SEPM). Here's why:

Incremental Updates: xdelta packages are incremental updates that only download changes since the last update, conserving bandwidth and speeding up client updates.

Content Revision Retention: SEPM needs to retain a sufficient number of content revisions to allow clients that check in intermittently (such as every 10 days) to download incremental rather than full content packages.

Default Retention Recommendation: Retaining 30 content revisions ensures that clients are covered for up to 10 days of updates, meeting the requirement for xdelta delivery.

This setup optimizes resource usage by reducing the load on network and client systems.

To improve access speed for client files stored on a file server, the administrator should Enable Network Cache within the client's Virus and Spyware Protection policy. This setting allows client machines to cache scanned files from the network, thus reducing redundant scans and increasing read speed from the server.

How Network Cache Enhances Read Speed:

When Network Cache is enabled, previously scanned files are cached, allowing subsequent access without re-scanning, which decreases latency and improves access speed.

Why Other Options Are Less Effective:

Adding the server to a trusted host group (Option B) does not directly impact file read speeds.

Creating a firewall allow rule (Option C) allows connectivity but does not affect the speed of file access.

Enabling download randomization (Option D) only staggers update downloads and does not relate to read speeds from a file server.

SONAR (Symantec Online Network for Advanced Response) checks the reputation of a process before convicting it. This reputation-based approach evaluates the trustworthiness of the process by referencing Symantec's database, which is compiled from millions of endpoints, allowing SONAR to make informed decisions about whether the process is likely benign or malicious.

Reputation Checking in SONAR:

Before taking action, SONAR uses reputation data to reduce the likelihood of false positives, which ensures that legitimate processes are not incorrectly flagged as threats.

This check provides an additional layer of accuracy to SONAR's behavioral analysis.

Why Other Options Are Incorrect:

Quarantining (Option A) and blocking behavior (Option B) occur after SONAR has convicted a process, not before.

Restarting the system (Option C) is not part of SONAR's process analysis workflow.

Symantec Insight is a technology that delivers reputation ratings for binary executables. This system leverages data from Symantec's Global Intelligence Network, which aggregates information from millions of users worldwide. Here's how it works:

File Reputation Database: Symantec Insight assigns a reputation score to each executable based on various factors, including prevalence, origin, and behavior.

Dynamic Decision Making: By consulting these ratings, SEP can dynamically determine if a file is safe or potentially harmful, allowing or blocking files accordingly.

Reduced False Positives: Insight helps reduce false positives, as it can distinguish between widely used legitimate files and rare, potentially risky files.

This reputation-based approach enhances protection by preemptively identifying suspicious files without relying on traditional signature-based detection alone.

In Symantec Endpoint Security Complete (SES Complete), the primary entities tracked include Endpoint, File, and Process. These entities represent the core components that SES Complete monitors and analyzes to detect, assess, and respond to potential threats.

Roles of Each Entity:

Endpoint: Represents devices within the environment, providing a focal point for security monitoring.

File: Refers to individual files that may be subject to threat detection and response actions.

Process: Encompasses active processes that could exhibit suspicious behaviors or be involved in attacks.

Why Other Options Are Incorrect:

Other combinations (Options B, C, and D) include Domain, which is not classified as a primary entity within SES Complete.
