1. Question 1

   What is the role of service providers to establish private connectivity between on-premises networks and Google Cloud resources?

   Afacilitate direct, dedicated network connections through Google Cloud Interconnect
   

   Benable intelligent routing and dynamic path selection using software-defined networking
   

   Cprovide end-to-end encryption for data transmission using native IPsec
   

   Daccelerate content delivery through integration with Google Cloud CDN
   

   Correct answer: A

   The role of service providers to establish private connectivity between on-premises networks and Google Cloud resources is to facilitate direct, dedicated network connections through Google Cloud Interconnect. Google Cloud Interconnect is a service that allows customers to connect their on-premises networks to Google Cloud through a service provider partner. This provides low latency, high bandwidth, and secure connectivity to Google Cloud services, such as Google Compute Engine, Google Cloud Storage, and Google BigQuery. Google Cloud Interconnect also supports hybrid cloud scenarios, such as extending on-premises networks to Google Cloud regions, or connecting multiple Google Cloud regions together. Google Cloud Interconnect offers two types of connections: Dedicated Interconnect and Partner Interconnect. Dedicated Interconnect provides physical connections between the customer's network and Google's network at a Google Cloud Interconnect location. Partner Interconnect provides virtual connections between the customer's network and Google's network through a supported service provider partner. Both types of connections use VLAN attachments to establish private connectivity to Google Cloud Virtual Private Cloud (VPC) networks.Reference:

2. Question 2

   Refer to the exhibits.

   

   

   Refer to the exhibits. An engineer must redistribute only the 10.0.10.0/24 network into BGP to connect an on-premises network to a public cloud provider. These routes are currently redistributed:

   

   Which command is missing on router R2?

   Aneighbor 10.0.10.2 remote-as 100
   

   Bredistribute ospf 1 match internal
   

   Credistribute ospf 1 match external
   

   Dneighbor 10.0.10.0/24 remote-as 100
   

   Correct answer: C

   The commandredistribute ospf 1 match externalis missing on router R2. This command is needed to redistribute only the external OSPF routes into BGP. The external OSPF routes are those that are learned from another routing protocol or redistributed into OSPF. In this case, the 10.0.10.0/24 network is an external OSPF route, as it is redistributed from EIGRP into OSPF on router R1. The other commands are either already present or not relevant for this scenario.Reference:=

3. Question 3

   A company with multiple branch offices wants a suitable connectivity model to meet these network architecture requirements:

   * high availability

   * quality of service (QoS)

   * multihoming

   * specific routing needs

   Which connectivity model meets these requirements?

   Ahub-and-spoke topology using MPLS with static routing and dedicated bandwidth for QoS
   

   Bstar topology with internet-based VPN connections and BGP for routing
   

   Chybrid topology that combines MPLS and SD-WAN
   

   Dfully meshed topology with SD-WAN technology using dynamic routing and prioritized traffic for QoS
   

   Correct answer: D

   A fully meshed topology with SD-WAN technology using dynamic routing and prioritized traffic for QoS meets the network architecture requirements of the company. A fully meshed topology provides high availability by eliminating single points of failure and allowing multiple paths between branch offices. SD-WAN technology enables multihoming by supporting multiple transport options, such as MPLS, internet, LTE, etc. SD-WAN also provides QoS by applying policies to prioritize traffic based on application, user, or network conditions. Dynamic routing allows the SD-WAN solution to adapt to changing network conditions and optimize the path selection for each traffic type. A fully meshed topology with SD-WAN technology can also support specific routing needs, such as segment routing, policy-based routing, or application-aware routing.Reference:

4. Question 4

   Which feature is unique to Cisco SD-WAN IPsec tunnels compared to native IPsec VPN tunnels?

   Areal-time dynamic path selection
   

   Btunneling protocols
   

   Cend-to-end encryption
   

   Dauthentication mechanisms
   

   Correct answer: A

   Cisco SD-WAN IPsec tunnels are different from native IPsec VPN tunnels in several ways. One of the unique features of Cisco SD-WAN IPsec tunnels is that they support real-time dynamic path selection, which means that they can automatically choose the best path for each application based on the network conditions and policies. This feature improves the performance, reliability, and efficiency of the network traffic. Native IPsec VPN tunnels, on the other hand, do not have this capability and rely on static routing or manual configuration to select the path for each tunnel. This can result in suboptimal performance, increased latency, and higher costs.Reference:=Traditional IPsec Versus Cisco SD-WAN IPsec,SD-WAN vs IPsec VPN's - What's the difference?,SD-WAN vs. VPN: How Do They Compare?,Traditional IPSEC Versus SD-WAN IPSEC

   
   

5. Question 5

   Refer to the exhibits.

   

   While troubleshooting, a network engineer discovers that the backup path fails between ASBR3 and ASBR4 for traffic between BGP AS6000 and BGP AS6500 when the connection between ASBR1 and ASBR2 goes down. The following configurations were performed on ASBR1:

   

   Which command is missing?

   Abgp additional-paths Install
   

   Bbgp additional-paths select
   

   Credistribute static
   

   Dbgp advertise-best-external
   

   Correct answer: D

   The bgp advertise-best-external command is used to enable the advertisement of the best external path to internal BGP peers. This command is useful when there are multiple exit points from the local AS to other ASes, and the local AS wants to use the closest exit point for each destination. By default, BGP only advertises the best path to its peers, and the best path is usually the one with the lowest IGP metric to the next hop. However, this may not be the optimal path for traffic leaving the local AS, as it may result in suboptimal hot-potato routing or MED oscillations. The bgp advertise-best-external command allows BGP to advertise the best external path, which is the path with the lowest MED among the paths from different neighboring ASes, in addition to the best path. This way, the internal BGP peers can choose the best exit point based on the MED value, rather than the IGP metric. In this scenario, ASBR1 is configured to receive additional paths from ASBR2, which is a route reflector. ASBR2 receives two paths for the same prefix from AS6500, one from ASBR3 and one from ASBR4. ASBR2 selects the best path based on the IGP metric to the next hop, and advertises it to ASBR1. However, this path may not be the best external path, as it may have a higher MED value than the other path. If the connection between ASBR1 and ASBR2 goes down, ASBR1 will not have any backup path to reach AS6500, as it does not know the other path from ASBR4. To prevent this situation, ASBR1 should be configured with the bgp advertise-best-external command, so that it can receive the best external path from ASBR2, along with the best path. This way, ASBR1 will have a backup path to reach AS6500, in case the primary path fails.Reference:=IP Routing: BGP Configuration Guide - BGP Additional Paths ... - Cisco,BGP Additional Paths
