After confirming correct routing:

The next step is toverify security zone assignments (Option A). If interfaces are not correctly assigned to zones, traffic will not be evaluated against proper inter-zone or intra-zone security policies, causing drops.

Option B:The routing protocol is irrelevant once the correct route lookup is confirmed.

Option C:NAT is checked later in the flow, not the immediate next step after routing.

Option D:ALG is only needed for specific applications (FTP, SIP), not general troubleshooting.

Correct Next Step:Verify that interfaces are assigned to the correct security zones.

In Junos OS, NAT rules are evaluated intop-down order. When a new rule is added, it is placed at thebottomof the rule set by default.

To move a rule to the top of the rule set, the command is:

set security nat source rule-set rule top

Option A (top):Correct. Moves the specified rule to the top of the list.

Option B (run):Used to execute operational commands, not rule reordering.

Option C (up):Not valid for reordering NAT rules.

Option D (insert):Not a supported NAT reordering command in Junos.

Correct Command:top

Security policies in Junos OS match traffic based on specific criteria:

Source and destination addresses(Option B).

Application(Option D), which may be defined as services (e.g., tcp/80) or recognized through AppID.

Other options:

MAC addresses(Option A) are not used in policy matching; policies operate at Layer 3/4.

Interface name(Option C) is used in firewall filters, not in security policy definitions.

Correct Criteria:Source address and Applications

The SRX Series devices support third-party antivirus scanning engines such asAvira. To use the Avira antivirus engine, administrators must explicitly enable the engine and ensure that the required components are properly loaded.

Enable in configuration mode:

The Avira antivirus engine must be enabled under UTM configuration mode. This step ensures the SRX device uses the Avira scanning engine for antivirus inspection.

Example:

set security utm feature-profile anti-virus avira-engine enable

Reboot the SRX device:

A system reboot is required after enabling the Avira engine to load the Avira antivirus components into memory.

Without a reboot, the Avira engine will not become active.

Why not the others?

Restarting themgdprocess (Option A) only reloads the management daemon and does not load antivirus engines.

Enabling inoperational mode(Option B) is not supported; the configuration must be applied in configuration mode.

Therefore, the correct actions to use Avira Antivirus are:Enable the Avira engine in configuration mode (Option D) and reboot the SRX device (Option C).
