 NTC/362: Fundamentals of Networking

Q: The exhibit shows a diagram of a small switched network. All switches use layer 2 switching and no layer 3 switching. The diagram identifies the root switch (switch SW1), and all root ports (RP) and designated ports (DP) for VLAN 10. All switches have the spanning-tree mode rapid-pvst command configured. The answers list ports that are neither root port nor designated port. Choose the answers that list an RSTP port role that is meaningful for that port in this topology.

A: SW3's F0/4 could be an RSTP alternate port, SW4's G0/1 could be an RSTP alternate port, SW4's F0/2 could be an RSTP backup port.

Explanation: First, for the answers that mention “backup port,” note that for a port to act as a backup port, it must back up a designated port on that same switch. Also, that backup port must connect to the same collision domain. The collision domains include all the point-to-point links between switches and the links connected to the one LAN hub. Based on these facts, neither SW3 nor SW2 can have a backup port, because each does not connect with two ports to the same collision domain. However, switch SW4 does connect with two ports to the same collision domain (as created by the hub), so SW4 could use port F0/2 as an RSTP backup port.

For the alternate port concept, each nonroot switch can have an alternate (root) port. The alternate cannot also be serving in the designated port role or already be serving in the root port role. Based on those rules, SW3's F0/4 and SW4's G0/1 could both be the alternate port. (SW2’s port G0/2 could be an alternate port as well, but it is not listed as an answer.)

 CYB 205 Infrastructure Administration Q: Alejandro is an incident response analyst for a large corporation. He is on the midnight shift when an intrusion detection system alerts him to a potential brute-force password attack against one of the company’s critical information systems. He performs an initial triage of the event before taking any additional action. A: Activate the incident response team. Explanation: The incident response process consists of a series of steps that start with detection and run through response, mitigation, reporting, recovery, and remediation, ending with a lessons learned and onward preparation phase. After the detection of a security incident, the next step in the process is the response, which should follow the organization’s formal incident response procedure. The first step of this procedure is activating the appropriate teams, including the organization's computer security incident response team (CSIRT).Answers A and D are incorrect. Lessons lear...

 CYB 205 Infrastructure Administration Q: Elaine is developing a business continuity plan for her organization. What value should she seek to minimize? A: RTO Explanation: Elaine should seek to minimize the recovery time objective value. The goal of business continuity planning exercises is to reduce the amount of time required to restore operations. This is done by minimizing the recovery time objective (RTO). RTO is the amount of time expected to return an IT service or component to operation after a failure.Answer C is incorrect. SLAs (service-level agreements) are written contracts that document service expectations.Answers B and D are incorrect. The Secure Socket Layer (SSL) and the Lightweight Directory Access Protocol (LDAP) are the network protocols.
