Question #11
Which four services does the architecture for Media Services contain? (Choose four.)
  1. A
    access services
  2. B
    transport services
  3. C
    storage services
  4. D
    forwarding services
  5. E
    session control services
  6. F
    security services
  7. G
    filtering services
  8. H
    remote access services

Correct Answer:
ABCE
An architecture framework for media services supports different models of video models. As shown in Figure 14-13, the network provides service to video media in the Media Services Framework. Those services are access services, transport services, bridging services, storage servers, and session control services, which arc provided to endpoints.
✑ Access services provide identity of end devices, mobility, and location services.
✑ Transport services provide QoS for reliable packet delivery.
✑ Bridging services provide transcoding, conferencing, and recording services of media streams.
✑ Storage services provide capture and storage of media streams and content management and distribution.
Session control services provide session signaling and control and gateway services.

Question #12
Refer to the exhibit.


Which layer is the distribution layer?
  1. A
    Layer A
  2. B
    Layer B
  3. C
    Layer C
  4. D
    Layers A and B form a consolidated core and distribution layer

Correct Answer:
B

Question #13
Which IPv6 feature enables routing to distribute connection requests to the nearest content server?
  1. A
    Link-local
  2. B
    Site-local
  3. C
    Anycast
  4. D
    Multicast
  5. E
    Global aggregatable

Correct Answer:
C
Any cast is a network addressing and routing methodology in which data grams from a single sender are routed to the topologically nearest node in a group of potential receivers all identified by the same destination address.

Question #14
What is the recommended spanning tree protocol to use for all Layer 2 deployments in a branch office environment?
  1. A
    CST
  2. B
    RSPT
  3. C
    PVST
  4. D
    MISTP
  5. E
    Rapid PVST +

Correct Answer:
E

Question #15
Refer to the exhibit.


A standard, Layer 2 campus network design is pictured. Which numbered box represents the distribution layer?
  1. A
    #1
  2. B
    #2
  3. C
    #3
  4. D
    #4

Correct Answer:
B

Question #16
Which two are types of network virtualization? (Choose two.)
  1. A
    VSS: Virtual Switching System
  2. B
    VRF: virtual routing and forwarding
  3. C
    VCI: virtual channel identifier
  4. D
    VLSM: variable length subnet masking
  5. E
    VM: virtual machine
  6. F
    VMP: Virtual Memory Pool

Correct Answer:
AB
Network virtualization encompasses logical isolated network segments that share the same physical infrastructure. Each segment operates independently and is logically separate from the other segments. Each network segment appears with its own privacy, security, independent set of policies, QoS levels, and independent routing paths.
Here are some examples of network virtualization technologies:
VLAN: Virtual local-area network
VSAN: Virtual storage-area network
VRF: Virtual routing and forwarding
VPN: Virtual private network
VPC: Virtual Port Channel

Question #17
You are tasked with designing a new branch office that will support 75 users with possible expansion in the future and will need a highly available network. Which of the branch design profiles should be implemented?
  1. A
    large branch design
  2. B
    medium branch design
  3. C
    teleworker design
  4. D
    small branch design

Correct Answer:
B
Medium Branch Design -
The medium branch design is recommended for branch offices of 50 to 100 users, which is similar to the small branch but with an additional access router in the
WAN edge (slightly larger) allowing for redundancy services. Typically, two 2921 or 2951 routers are used to support the WAN, and separate access switches are used to provide LAN connectivity.

Question #18
Which two can be used as a branch office WAN solution? (Choose two.)
  1. A
    frame relay
  2. B
    MPLS
  3. C
    Metro Ethernet
  4. D
    GPRS
  5. E
    dial-up modem
  6. F
    3G USB modems

Correct Answer:
BC
Frame relay is old 'shared' technology today's sites use some flavor or Metro E or MPLS/VPN

Question #19
What is the acceptable amount of one-way network delay for voice and video applications?
  1. A
    300 bytes
  2. B
    1 sec
  3. C
    150 ms
  4. D
    500 ms

Correct Answer:
C
Delay Components in VoIP Networks
The ITU's G.I 14 recommendation specifics that the one-way delay between endpoints should not exceed 150 ms to be acceptable, commercial voice quality. In private networks, somewhat longer delays might be acceptable for economic reasons. The ITU G.114 recommendation specifics that 151-ms to 400-ms one-way delay might be acceptable provided that organizations are aware that the transmission time will affect the quality of user applications. One-way delays of above
400 ms are unacceptable for general network planning purposes.

Question #20
Which mode is used to exclusively look for unauthorized access points?
  1. A
    monitor mode
  2. B
    sniffer mode
  3. C
    rogue detector mode
  4. D
    local mode

Correct Answer:
C


Interference detection and avoidance: As Cisco LWAPs monitor all channels, interference is detected by a predefined threshold (10 percent by default).
Interference can be generated by rogue APs, microwaves, cordless telephones, Bluetooth devices, neighboring WLANs, or other electronic devices.
