Internet Key Exchange (IKE) is responsible for which two functions? (Choose Two) Establishing Network speed parameters Verifying the Client's patch level Negotiating algorithms to use. Exchanging key information.

Negotiating algorithms to use. Exchanging key information. Internet Key Exchange (IKE) negotiates the IPSec security associations (SAs). This process requires that the IPSec systems first authenticate themselves to each other and establish ISAKMP (IKE) shared keys. In phase 1 of this process, IKE creates an authenticated, secure channel between the two IKE peers, called the IKE security association. The Diffie-Hellman key agreement is always performed in this phase. In phase 2, IKE negotiates the IPSec security associations and generates the required key material for IPSec. The sender offers one or more transform sets that are used to specify an allowed combination of transforms with their respective settings. The sender also indicates the data flow to which the transform set is to be applied. The sender must offer at least one transform set. The receiver then sends back a single transform set, which indicates the mutually agreed-upon transforms and algorithms for this particular IPSec session.

What are two characteristics of Fiber Optic Cable? (Choose Two) Conducts Electricity Requires metal conduit Supports Splicing Requires a policy for end connectors.

Supports Splicing Requires a policy for end connectors. C: A mechanical splice is a junction of two or more optical fibers that are aligned and held in place by a self-contained assembly (usually the size of a large carpenter’s nail).[1] The fibers are not permanently joined, just precisely held together so that light can pass from one to another. D: Modern connectors typically use a “physical contact” polish on the fiber and ferrule end. This is a slightly convex surface with the apex of the curve accurately centered on the fiber, so that when the connectors are mated the fiber cores come into direct contact with one another.

They require a Router to connect to VLANs on another Switch. They compartmentalize a Network and isolate Traffic. They act as though they are on the same LAN regardless of Physical Location. VLANs provide the following advantages: * (E) VLANs enable logical grouping of end-stations that are physically dispersed on a network. … * VLANs reduce the need to have routers deployed on a network to contain broadcast traffic. … * (C) Confinement of broadcast domains on a network significantly reduces traffic. By confining the broadcast domains, end-stations on a VLAN are prevented from listening to or receiving broadcasts not intended for them. * (B) If a router is not connected between the VLANs, the end-stations of a VLAN cannot communicate with the end-stations of the other VLANs.

What are two characteristics of the CSMA/CD Access Method? (Choose Two) It checks to see if a Collision has been detected. It does a round robin search for requests to transmit from all nodes on the Network. It signals its intent to transmit on the Network. It waits until the Transmission medium is idle.

It checks to see if a Collision has been detected. | It waits until the Transmission medium is idle.

What are two characteristics of a Mesh Network Topology? (Choose Two) It is fault tolerant because of redundant connections. Every node connects to every other node on the network. It works best for Networks with a large number of nodes. It requires less cabling than either a star or ring topology.

What is a similarity between Layer 2 and Layer 3 Switches? Both provide a high level of Security to the Network Both use Logical Addressing to forward transmissions. Both forward packets onto the Network Both allow the implementation of VLANs

Both allow the implementation of VLANs. A single layer-2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them via one or more routers; such a domain is referred to as a virtual local area network, virtual LAN or VLAN. LANs are layer 2 constructs, so they can be supported by both Layer 2 and Layer 3 switches. Incorrect: Not A: Layer 2 switches do not provide high level of security. Not B: Another name for logical address is IP address. Only Layer 3 switches uses IP address. Layer 2 switches uses MAC addresses. Not C: only Layer 3 switches forward packets on the network (like routers).

Which metric does Routing Information Protocol (RIP) use to determine the least costly route? Delay Host ID Hop Count Interface

Hop Count

What are two differences between Switches and Hubs? (Choose Two) Switches are slower than Hubs because of the extra addressing functions that Switches perform. Switches send data to all of the computers that are connected to them for efficiency. Switches are capable of sending and receiving data at the same time. Switches identify the intended destination of the data that they receive.

Switches are slower than Hubs because of the extra addressing functions that Switches perform. Switches identify the intended destination of the data that they receive. Hubs repeat everything they receive and can be used to extend the network. Switches control the flow of network traffic based on the address information in each packet. A switch learns which devices are connected to its ports (by monitoring the packets it receives), and then forwards on packets to the appropriate port only. This allows simultaneous communication across the switch, improving bandwidth.

What happens when an 802.11a node broadcasts within range of an 802.11g Access Point? The Access Point transmits, but the node is unable to receive. A Connection occurs Both the node and the Access Point are unable to transmit. The node transmits, but the Access Point is unable to receive.

The node transmits, but the Access Point is unable to receive. (Because a and g operate on different Frequencies. a = 5GHz g = 2.4GHz
