Link aggregation, also known as IEEE 802.3ad or 802.1ax, enables the binding of multiple physical interfaces to form a single logical interface, which increases the overall bandwidth and provides redundancy. This is achieved by combining the bandwidth of the individual links into one aggregated link. For example, if two 1Gbps interfaces are aggregated, the logical link can provide up to 2Gbps bandwidth. This configuration is commonly used in FortiGate devices to enhance network performance without replacing hardware. The option B correctly describes this by stating "Increase bandwidth by binding physical interfaces into a single channel," which aligns with the official description. Incorrect options include A, which is vague and does not specify the method of binding multiple interfaces; C, which is the opposite of the purpose; and D, which is invalid. Exact extract: Link aggregation (IEEE 802.3ad/802.1ax) enables you to bind two or more physical interfaces together to form an aggregated (combined) link. This new link ... Link aggregation combines multiple physical interfaces into a single logical interface, increasing bandwidth and link redundancy. Traffic is distributed evenly.
Question 2
Which of the following is a network monitoring protocol?
Options:
A.
RDP
B.
Telnet
C.
SNMP
D.
SSH
Answer:
C
Explanation:
SNMP (Simple Network Management Protocol) is specifically designed for monitoring and managing network devices, allowing administrators to query device status, performance metrics, and configure alerts for issues. It operates by using agents on devices that report to a central manager. In contrast, RDP is for remote desktop access, Telnet for unsecure remote command-line access, and SSH for secure remote access. SNMP is the standard protocol for network monitoring in Fortinet products like FortiGate, FortiSwitch, etc. Exact extract: SNMP enables administrators to monitor how devices are performing and make changes to network devices so that data moves through the network more efficiently. Simple Network Management Protocol (SNMP) enables you to monitor hardware on your network. The FortiSwitch SNMP implementation is read-only. Monitoring FortiAP with SNMP. You can enable SNMP directly on FortiAP by implementing a SNMPD daemon/subagent on the FortiAP side. The Simple Network Management Protocol (SNMP) allows you to monitor hardware on your network. You can configure the hardware, such as the FortiProxy SNMP agent.
Question 3
Which of these BGP paths will be the preferred one ?
Options:
A.
Prefer External path (learned via EBGP) over Internal path (IBGP)
B.
Prefer the path with the shortest AS Path
C.
Prefer the path with the lowest Multi-Exit Discriminator (MED)
D.
Prefer the path with the highest Local Preference value
Answer:
D
Explanation:
BGP path selection follows a specific order of attributes to determine the best path. The process prefers the path with the highest local preference first, as it is one of the earliest steps in the decision process. Local preference is used within an AS to influence outbound traffic. Only if local preferences are equal does it move to the next criteria, such as shortest AS path. The AS path length is considered after local preference, MED after that, and eBGP over iBGP even later. Therefore, among the options, the highest local preference (D) is the most preferred criterion. The original document's answer B is incorrect based on standard BGP selection rules implemented in Fortinet. Exact extract: This article describes the BGP route selection process. Scope FortiGate. Solution Consider only routes with no AS loops and a valid next hop. BGP makes routing decisions based on path, network policies and rulesets ... select the route with the lowest router ID as the best path. Network. Type. To achieve this, multiple route selection techniques can be used. Some are protocol-agnostic (for example, weight) and others are protocol-specific (for example ...).
