Exam SY0-601 topic 1 question 191 discussion

A jump server, jump host or jump box is a system on a network used to access and manage devices in a separate security zone. A jump server is a hardened and monitored device that spans two dissimilar security zones and provides a controlled means of access between them

Being CCNA certified twice, that’s VLAN to me, so it’s A.

D. Jump servers: Jump servers, also known as bastion hosts, are secure intermediary servers that allow administrators to access devices in different network segments. By deploying jump servers, administrators can connect to both production and development servers through a centralized access point without direct communication between the server networks. A. VLANs (Virtual Local Area Networks): While VLANs can logically segment the network, they do not prevent communication between different VLANs within the same physical network. Therefore, they would not meet the requirement of ensuring that production and development servers cannot communicate with each other directly.

Key word = two VLANs

A jump server (sometimes called a jump box) is a hardened server used to access and manage devices in another network with a different security zone. As an example, if administrators want to administer servers in the screened subnet from the internal network, they could use a jump server. They could connect to the jump server and then access servers in the screened subnet through the jump server.

The dump is good. I had score 800 in 01th of february/2024 90% be here !!!!

A - VLAN, hopefully you took Network+. The jumpbox and management workstation should only have the minimum required software to perform their job and be well hardened. It is only meant to provide access for security. The questions mentions for production and development. If you have minimum software, you cant have full production or development to test, a VLAN provides that.

VLAN is esactly "dedicated network that cannot communicate with one another directly". I don understand how cold be possible other options.

D. Jump servers

The keyword here is "Access". Jump Server is what you use to gain access. VLAN will be incorrect given the keywords of the question.

None of these answers make sense. I think we ca leave explanation for B and C and focus on A and D. A: subnets(VLANs) have been already created, so we don't need do it for the second time. D: Jump server for what? Access is blocked between newly created subnets, not between admin's VLAN and new subnets. But, I'd go with D if I had to choose as it makes more sense here

" network engineer CREATED two subnets that will be used for production and development servers." The second statement imo is just laying the foundation for the test taker of how the two servers are to be separated by company policy. The question is asking how the admin could access both. You have to rephrase it, so it makes more sense. This essentially boils down to "Per company policy, which states the testing and development servers must not be able to communicate with each other, a network engineer created two subnets following said policy. What can be deployed to allow an admin to access each server?"

D as the question states that the 2 subnets have been created, and how can these subnets be accessed. The jumpbox does exactly this.

A.) VLAN and not D.) jump server A jump server assumes that these are already separated but the question is asking what solution will separate these 2 areas securely and they can access? It states that they need to be separated, which is what the VLAN does, and that "server administrators can access these devices" not that they need to access between them. In other words you're putting the horse before the cart if you choose jump server.

Jump servers

A Jump server (also known as a bastion host or a jump host) is a hardened and highly secured server that acts as an intermediary or access point for administrators to connect to other servers within isolated networks. When an administrator needs to access a server in either the production or development subnet, they first connect to the Jump server. From the Jump server, they can then establish a separate connection to the target server they need to manage or configure.

Jump server. The question is not about separating 2 networks, it’s already done as explained in the question. The question is about you have 2 subnets and you need to manage both, which the Jump Server can do.
