  ip route vrf Customer2 192.168.1.200 255.255.255.255 192.168.1.1 Customer1

• C.p route vrf Customer1 172.16.1.1 255.255.255.255 172.16.1.1 global
  ip route vrf Customer2 192.168.1.200 255.255.255.0 192.168.1.1 global
  ip route 192.168.1.0 255.255.255.0 Vlan10
  ip route 172.16.1.0 255.255.255.0 Vlan20

• D.ip route vrf Customer1 172.16.1.0 255.255.255.0 172.16.1.1 global
  ip route vrf Customer2 192.168.1.200 255.255.255.255 192.168.1.1 global
  ip route 192.168.1.0 255.255.255.0 Vlan10
  ip route 172.16.1.0 255.255.255.0 Vlan20

Answer explanation

Choice D correctly configures routes for both Customer1 and Customer2, allowing Customer2 to access Customer1's FTP server at 192.168.1.200 by using the global routing table for proper connectivity.

Which two actions provide controlled Layer 2 network connectivity between virtual machines running on the same hypervisor? (Choose two)

• • A. Use a single routed link to an external router on stick

• • B. Use a single trunk link to an external Layer2 switch

• • C. Use VXLAN fabric after installing VXLAN tunnelling drivers on the virtual machines

• • D. Use a virtual switch running as a separate virtual machine

• • E. Use a virtual switch provided by the hypervisor

Answer explanation

Using a single trunk link to an external Layer 2 switch (B) and a virtual switch provided by the hypervisor (E) ensures controlled Layer 2 connectivity between VMs on the same hypervisor, allowing for proper traffic management.

Which element enables communication between guest VMs within a virtualized environment?

• • A. vSwitch

• • B. pNIC

• • C. virtual router

• • D. hypervisor

Answer explanation

The vSwitch (virtual switch) facilitates communication between guest VMs in a virtualized environment by connecting their virtual network interfaces, allowing them to communicate as if they were on the same physical network.

A server running Linux is providing support for virtual machines along with DNS and DHCP services for a small business. Which technology does this represent?

• • A. container

• • B. Type 1 hypervisor

• • C. Type 2 hypervisor

• • D. hardware pass-through

  
  

Answer explanation

A Type 2 hypervisor runs on a host operating system, allowing it to manage virtual machines while providing services like DNS and DHCP. This setup is typical for small businesses using Linux for virtualization.

A customer has deployed an environment with shared storage to allow for the migration of virtual machines between servers with dedicated operating systems that provide the virtualization platform. What is this operating system described as?

• • A. type 1 hypervisor

• • B. container oriented

• • C. hosted virtualization

• • D. decoupled

Answer explanation

The operating system described is a type 1 hypervisor, which runs directly on the hardware and allows for the migration of virtual machines between servers using shared storage.

What is a Type 1 hypervisor?

• • A. run on a virtual server and includes its own operating system

• • B. runs directly on a physical server and depends on a previously installed operating system

• • C. runs on a virtual server and depends on an already installed operating system

• • D. runs directly on a physical server and includes its own operating system

Answer explanation

A Type 1 hypervisor runs directly on a physical server and includes its own operating system, allowing it to manage hardware resources efficiently. This makes option D the correct choice.

What is a benefit of using a Type 2 hypervisor instead of a Type 1 hypervisor?

• • A. improved security because the underlying OS is eliminated

• • B. better application performance

• • C. ability to operate on hardware that is running other OSs

• • D. improved density and scalability

Answer explanation

A Type 2 hypervisor can run on top of an existing operating system, allowing it to utilize hardware that is already running other OSs. This flexibility is a key benefit compared to Type 1 hypervisors, which require direct hardware access.

What is the purpose of the LISP routing and addressing architecture?

• • A. It creates head-end replication used to deliver broadcast and multicast frames to the entire network.

• • B. It creates two entries for each network node, one for its identity and another for its location on the network.

• • C. It allows multiple instances of a routing table to co-exist within the same router.

• • D. It allows LISP to be applied as a network visualization overlay though encapsulation.

Answer explanation

The purpose of the LISP routing and addressing architecture is to create two entries for each network node: one for its identity (EID) and another for its location (RLOC), facilitating better routing and mobility.

Refer to the exhibit. Which LISP component do routers in the public IP network use to forward traffic between the two networks?

• • A. map resolver

  
  

• • B. map server

  
  

• • C. EID

  
  

• D. RLOC
  

Answer explanation

RLOC (Routing Locator) is used by routers in the public IP network to forward traffic between networks in LISP. It identifies the location of the endpoint in the routing system, making it the correct choice.

Which LISP infrastructure device provides connectivity between non-LISP sites and LISP sites by receiving non-LISP traffic with a LISP site destination?

• • A. PETR

• • B. map resolver

• • C. PITR

• • D. map server

Answer explanation

The correct answer is C. PITR (Proxy Ingress Tunnel Router), which connects non-LISP sites to LISP sites by handling non-LISP traffic destined for LISP sites, facilitating communication between different network architectures.
