Correct Answer: C

Correct Answer: A

Correct Answer: A

NGFW (Next-Generation Firewall): NGFWs are advanced security devices that go beyond traditional firewalls. They provide filtering and inspection capabilities at multiple OSI layers, including application-layer filtering, intrusion prevention, and advanced threat protection. NGFWs are designed to offer more sophisticated and comprehensive security features compared to traditional routers.

Correct Answer: A

A memorandum of understanding (MOU) is a document that describes an agreement between two or more parties on how to utilize shared resources for a project. An MOU is not legally binding, but it outlines the expectations and responsibilities of each party involved in the collaboration. An MOU can be used when two international companies want to share cloud resources for a project without creating a formal contract.

Correct Answer: A

BGP (Border Gateway Protocol): BGP is designed for routing between different autonomous systems (ASes) on the internet. It is used to exchange routing and reachability information between ISPs, enterprises, and other networks. BGP is well-suited for handling large-scale networks and providing policy-based routing control.

Correct Answer: D

A Service-level agreement (SLA) is a document that outlines the responsibilities of a cloud service provider and the customer. It typically includes the agreed-upon availability of the cloud service provider, the expected uptime for the service, and the cost of any downtime or other service interruptions. Consulting the SLA is the best way for the management team to determine the promised availability of the cloud provider. Reference: CompTIA Cloud+ Study Guide, 6th Edition, page 28.

Correct Answer: B

Correct Answer: A

A DHCP scope option can be used to specify the location of configuration files for VoIP phones, by including the address of the file server as an option in the DHCP scope. The DHCP server can then provide this information to the VoIP phones when they request an IP address, so that they know where to download the configuration files from. This allows the administrator to centrally manage the configuration of the phones, rather than having to manually configure each one.

Correct Answer: BD

TIA-568-B: TIA-568-B : TIA-568 is a standard for commercial building telecommunications cabling. TIA-568-B is a standard for terminating twisted pair cables, it is commonly used in networking. The TIA-568-B standard is used for both ends

of the cable, as the switch is not capable of Auto-MDI-X. This means that the cable ends must be wired in a specific way to ensure that the correct connections are made.

RJ45: RJ45 is a type of connector commonly used for Ethernet cables. It is a 8-pin connector that is used to connect twisted-pair cables to networking devices such as switches, routers, and PCs.

Correct Answer: A

Elastic computing involves the allocation of resources on demand, so that the resources available to a virtual web server can be increased or decreased as needed in order to handle varying levels of traffic or demand. This can help to ensure that the web server has the resources it needs to handle any workload, without wasting resources when demand is low.

Scalable networking refers to the ability of a network to expand or contract as needed in order to meet changing demand. Hybrid deployment involves the use of a combination of on-premises and cloud-based resources. Multitenant hosting involves the use of a single instance of a software application to serve multiple customers, each with their own customized version of the application.

Correct Answer: B

TFTP Server: Setting up a TFTP (Trivial File Transfer Protocol) server allows you to store the security update files in one location. This avoids the need to transfer files individually to each switch.

SSH: Secure Shell (SSH) is a secure protocol used for remote access and management of network devices. SSH provides encryption and secure authentication, making it the preferred method for accessing devices remotely.

Correct Answer: D

Change management documentation is a record of the changes that have been made to a system or process, including the reason, date, time, and impact of each change. A technician can reference this documentation to find what solution was implemented to resolve a previously encountered issue, as well as any potential side effects or dependencies of the change.

Correct Answer: B

Giants are packets that exceed the configured MTU (Maximum Transmission Unit) of a switchport or interface, which causes them to be dropped or fragmented by the switch or router. The MTU is the maximum size of a packet that can be transmitted without fragmentation on a given medium or protocol. Giants can indicate misconfiguration or mismatch of MTU values between devices or interfaces on a network, which can cause performance issues or errors. CRC errors are errors that occur when the cyclic redundancy check (CRC) value of a packet does not match the calculated CRC value at the destination, which indicates corruption or alteration of data during transmission due to noise, interference, faulty cabling, etc., but not necessarily exceeding MTU values. Runts are packets that are smaller than the minimum size allowed by the medium or protocol, which causes them to be dropped or ignored by the switch or router. Flooding is a technique where a switch sends packets to all ports except the source port when it does not have an entry for the destination MAC address in its MAC address table, which can cause congestion or broadcast storms on a network.
