  1. The NAT cannot be used in easy IP mode.
  2. VRIDs of the VRRP must be bound with the NAT during NAT configuration in the outbound direction between domain.
  3. VRIDs of the VRRP do not need to be bound with the NAI during NAI configuration in the outbound direction between domains.
  4. The FTP Nat Alg function must be enabled on the firewall

As shown in the figure, the bearer network is deployed in full mesh mode. For example, RTA uses the physical interface ATM 1/0/0. The interface is devised into ATM 10/0.2 connect to RTC and RTD, respectively . The GigabiteEthernet 2/0/0 and GigabitEthernet 3/0/0 interface are used to set up a trunk as the VRRP heartbeat cable. The UMG work in active/standby mode. Media interface connected to RTA and RTB belong to VLAN 10. VRRP is enable at the VLAN interface RTA is the master router. The interface is configured as follows:



Which of the following RTA configurations are correct in VLAN 10? A)



B)



C)



D)

  1. Option A
  2. Option B
  3. Option C
  4. Option D

Answer(s): D



Exhibit:



The figure shows the typically mode in which a common softswitch access the bearer network. VRRP is enabled on RTA and RTB. In normal cases, RTA is the VRRP master router and RTB is the VRRP is the VRRP salve router. The ETH_trunk is enabled between RTA RTB. IF VRRP is not bounded to BFD and each [parameter uses their default settings, which statement is the true when the upstream link of RTA is faulty?

  1. RTB cannot receive the heartbeat packet from RTA, and both routers become master routers.
  2. The VRRP status remain unchanged but the downstream traffic is directly forwarded from RTB to the MSoftx.
  3. The ARRP status remain unchanged but the downstream traffic is forwarded from RTB to the MSoft through RTA
  4. The ARRP status immediately between RTA and RTB and RTB, and RTB becomes the master router.

Answer(s): C

  1. Option A
  2. Option B
  3. Option C
  4. Option D

Answer(s): D



User A want to obtain a better network service for business development and signs an SLA with a corner. User A purchases a bandwidth of 5 Mbit/s to ensure the voice service (requiring short delay), vide service, key data services, and other services, If you were corner network administrator.
What would you do on the PE to ensure these services?

  1. Mark the VoIP service as EF, set the CIR to 0Mbit/s, and set the PIR to 1 Mbit/s mark the video service as AF 4 and set the CIR and PIR to 2 Mbit/s mark key data services as AF3, set the CIR to 1 Mbit/s and the PIR to 5 Mbit/s: mark other services as AF1, set the CIR to 2 Mbit/s and Set PIR to 5 Mbit/s.
  2. Mark the VoIP service as EF, set the CIR to 0Mbit/s, and set the PIR to 1 Mbit/s mark the video service as AF 4 and set the CIR and PIR to 2 Mbit/s mark key data services as AF3, set the CIR to 1 Mbit/s and the PIR to 5 Mbit/s: mark other services as AF1, set the CIR to 2 Mbit/s and Set PIR to 5 Mbit/s.
  3. Mark the VoIP service as EF, set the CIR to 1 0Mbit/s, and set the PIR to 1 Mbit/s mark the video service as AF 4 and set the CIR and PIR to 2 Mbit/s mark key data services as AF3, set the CIR to 2 Mbit/s and the and the PIR to 5 Mbit/s : mark other services as BE, set the CIR to 0 Mbit/s and set PIR to 5 Mbit/s.
  4. Mark the VoIP service as EF, set the CIR to 2 Mbit/s: marks the video service as AF 3 and set the CIR and PIR to 2 Mbit/s: mark key data services as AF4, set the CIR to 2 Mbit/s and the PIR to 5 Mbit/s mark other service as BE, set the CIR to 0 Mbit./s and set PIR to 5 Mbit/s
