Exam DEA-1TT4 topic 1 question 10 discussion

A is correct, C is not correct that it should be combined into a logical ISL not physical.

A is the correct answer as the question asks for the benefits of Link aggregation C Describes the definition of link aggregation

Link aggregation combines two or more parallel ISLs into a single logical ISL. "Two or more" not only two,so A correct.

C is not correct as "combining two parallel ISLs" does NOT put it "into a single PHYSICAL ISL". The word "physical" is completely wrong here. So i think the correct answer is A.

Both A & C are correct. Link aggregation combines two or more parallel ISLs into a single logical ISL, called a port-channel, yielding higher throughput than a single ISL could provide. For example, the aggregation of 10 ISLs into a single port-channel provides up to 160 Gb/s throughput assuming the bandwidth of an ISL is 16 Gb/s. Link aggregation optimizes fabric performance by distributing network traffic across the shared bandwidth of all the ISLs in a port-channel. This allows the network traffic for a pair of node ports to flow through all the available ISLs in the port-channel rather than restricting the traffic to a specific, potentially congested ISL.

The link is good, reading the content leads to answer C

Should be C based on the below. "Link aggregation combines two or more parallel ISLs into a single logical ISL, called a port-channel, yielding higher throughput than a single ISL could provide"

Should be C
