NEW QUESTION 29
Which two statements about IP SLA are true? (Choose two)
- A. It uses active traffic monitoring correct
- B. The IP SLA responder is a component in the source Cisco device
- C. It is Layer 2 transport-independent correct
- D. It can measure MOS
- E. SNMP access is not supported
- F. It uses NetFlow for passive traffic monitoring
Answer: A,C
Explanation:
Explanation
IP SLAs allows Cisco customers to analyze IP service levels for IP applications and services, to increase productivity, to lower operational costs, and to reduce the frequency of network outages. IP SLAs uses active traffic monitoring-the generation of traffic in a continuous, reliable, and predictable manner-for measuring network performance.
Being Layer-2 transport independent, IP SLAs can be configured end-to-end over disparate networks to best reflect the metrics that an end-user is likely to experience.

NEW QUESTION 34
Which statement describes the IP and MAC allocation requirements for virtual machines on types 1 hypervisors?
- A. Each virtual machine requires a unique IP and MAC addresses to be able to reach to other nodes.
- B. Each virtual machine requires a unique IP address but shares the MAC address with the physical server
- C. Each virtual machines requires a unique IP address but shares the MAC address with the address of the physical server.
- D. Each virtual machine requires a unique MAC address but shares the IP address with the physical server.
Answer: A
Explanation:
Explanation
A virtual machine (VM) is a software emulation of a physical server with an operating system.
From an application's point of view, the VM provides the look
and feel of a real physical server, including all its components, such as CPU, memory, and network interface cards (NICs).
The virtualization software that creates VMs and performs the hardware abstraction that allows multiple VMs to run concurrently is known as a hypervisor.
There are two types of hypervisors: type 1 and type 2 hypervisor.
In type 1 hypervisor (or native hypervisor), the hypervisor is installed directly on the physical server. Then instances of an operating system (OS) are installed on the hypervisor. Type 1 hypervisor has direct access to the hardware resources. Therefore they are more efficient than hosted architectures. Some examples of type 1 hypervisor are VMware vSphere/ESXi, Oracle VM Server, KVM and Microsoft Hyper-V.
In contrast to type 1 hypervisor, a type 2 hypervisor (or hosted hypervisor) runs on top of an operating system and not the physical hardware directly. answer 'Each virtual machine requires a unique IP and MAC addresses to be able to reach to other nodes' big advantage of Type 2 hypervisors is that management console software is not required. Examples of type 2 hypervisor are VMware Workstation (which can run on Windows, Mac and Linux) or Microsoft Virtual PC (only runs on Windows).

Answer: A
Explanation:

NEW QUESTION 40
What are two common sources of interface for WI-FI networks? (Choose two.)
- A. LED lights
- B. fire alarm
- C. radar
- D. conventional oven
- E. rogue AP
Answer: D,E
Explanation:
Interference between different WLANs occurs when the access points within range of each other are set to the same RF channel.
Microwave ovens emit damaging interfering signals at up to 25 feet or so from an operating oven.
Some microwave ovens emit radio signals that occupy only a third of the 2.4-GHz band, whereas others occupy the entire band.

NEW QUESTION 41
Which two GRE features are configured to prevent fragmentation? (Choose two.)
- A. TCP MSS
- B. TCP window size
- C. MTU ignore
- D. PMTUD
- E. DF bit Clear
- F. IP MTU
Answer: A,D
Explanation:
The IP protocol was designed for use on a wide variety of transmission links. Although the maximum length of an IP datagram is 65535, most transmission links enforce a smaller maximum packet length limit, called an MTU. The value of the MTU depends on the type of the transmission link. The design of IP accommodates MTU differences since it allows routers to fragment IP datagrams as necessary. The receiving station is responsible for the reassembly of the fragments back into the original full size IP datagram.
Fragmentation and Path Maximum Transmission Unit Discovery (PMTUD) is a standardized technique to determine the maximum transmission unit (MTU) size on the network path between two hosts, usually with the goal of avoiding IP fragmentation. PMTUD was originally intended for routers in IPv4. However, all modern operating systems use it on endpoints.
The TCP Maximum Segment Size (TCP MSS) defines the maximum amount of data that a host is willing to accept in a single TCP/IP datagram. This TCP/IP datagram might be fragmented at the IP layer. The MSS value is sent as a TCP header option only in TCP SYN segments. Each side of a TCP connection reports its MSS value to the other side. Contrary to popular belief, the MSS value is not negotiated between hosts. The sending host is required to limit the size of data in a single TCP segment to a value less than or equal to the MSS reported by the receiving host.
TCP MSS takes care of fragmentation at the two endpoints of a TCP connection, but it does not handle the case where there is a smaller MTU link in the middle between these two endpoints.
PMTUD was developed in order to avoid fragmentation in the path between the endpoints. It is used to dynamically determine the lowest MTU along the path from a packet's source to its destination.
