350-401 Practice Test 49 — 15 Questions

Question 1

Drag and drop each queuing mechanism on the left to its matching use case on the right.

Accepted Answer

PQ: Strict priority for delay-sensitive traffic. PQ provides strict priority for delay-sensitive traffic, CBWFQ guarantees bandwidth for defined classes, LLQ combines strict priority with CBWFQ for real-time traffic, WFQ provides fair queuing for all flows, CBWFQ is used for data traffic requiring bandwidth guarantees.

Question 2

Which three statements about OSPF route summarization are true? (Choose three.)

Accepted Answer

Inter-area route summarization is configured on ABRs using the "area range" command.. Inter-area summarization is configured on ABRs to reduce the number of Type 3 LSAs. Option B is correct because external route summarization is configured on ASBRs to reduce Type 5 LSAs. Option C is correct because summarization helps reduce the routing table size and LSA flooding, improving network stability. Option D is incorrect because summarization is not supported on internal routers; it is only performed on ABRs and ASBRs. Option E is incorrect because summarization does not affect Type 1 or Type 2 LSAs; it only affects Type 3 and Type 5 LSAs.

Answer

Route summarization can be configured on any OSPF router to reduce Type 1 LSAs.

Answer

Summarization in OSPF can be applied to Type 1 and Type 2 LSAs to reduce flooding.

Question 3

Drag and drop the steps of BGP confederations setup between sub-ASes into the correct order, from first to last.

Accepted Answer

Set bgp confederation identifier. First, you assign the confederation identifier (main AS). Then you define the member sub-AS numbers. Next, you configure eBGP peering between sub-ASes using the sub-AS numbers. After that, you ensure iBGP is configured within each sub-AS. Finally, you verify confederation peers with show ip bgp neighbors.

Question 4

Drag and drop each VM storage type on the left to its matching characteristic on the right.

Accepted Answer

Thin: Allocates storage only as data is written. Thin provisioning allocates space on demand. Thick provisioning allocates all space at creation. RDM (Raw Device Mapping) provides direct access to a LUN. VMDK is the virtual disk file format. VHDX is Microsoft’s virtual hard disk format.

Question 5

Which three statements about virtual machine (VM) resource allocation and overcommitment are true? (Choose three.)

Accepted Answer

Memory overcommitment allows the sum of all virtual machine memory allocations to exceed the physical RAM of the host.. Memory overcommitment allows more total vRAM than physical RAM. CPU overcommitment is common and can be managed. Overcommitment can cause performance issues if resources are oversubscribed. Storage is not typically overcommitted in the same manner as CPU/memory.

Answer

Overcommitment always guarantees better performance for all virtual machines.

Answer

A hypervisor cannot overcommit CPU resources because each vCPU must be pinned to a dedicated physical core.

Question 6

Which three statements about EIGRP named mode configuration are true? (Choose three.)

Accepted Answer

Named mode uses the 'router eigrp <name>' command to enter configuration mode.. EIGRP named mode uses a hierarchical configuration under a single router process, supporting address families (IPv4, IPv6) and VRFs. It simplifies configuration and allows per-interface settings.

Answer

In named mode, the network statement is replaced by the 'af-interface' configuration under the address family.

Answer

Named mode requires the 'no shutdown' command under the address family to enable EIGRP.

Question 7

Drag and drop the steps of EIGRP named mode configuration steps into the correct order, from first to last.

Accepted Answer

Create the EIGRP named mode instance. EIGRP named mode uses an address-family configuration. First, create the named EIGRP instance, then enter address-family IPv4, configure the network, optionally adjust timers, and finally verify the configuration.

Question 8

Drag and drop each Cisco campus design model component on the left to its matching description on the right.

Accepted Answer

Access layer switch: Provides port density and PoE for end devices. The campus design uses a hierarchical model with access, distribution, core layers; SVI provides Layer 3 gateway; VSS virtualizes switches; StackWise combines physical switches; PoE powers endpoints.

Question 9

Which two statements about NFV MANO (Management and Orchestration) are true? (Choose two.)

Accepted Answer

The VNF Manager (VNFM) is responsible for the lifecycle management of VNF instances, including instantiation and scaling.. NFV MANO consists of three main components: NFV Orchestrator (NFVO), VNF Manager (VNFM), and Virtualized Infrastructure Manager (VIM). The NFVO coordinates network services across multiple VNFs, the VNFM manages individual VNF instances, and the VIM controls the NFVI resources. Option A is correct because the VNFM handles VNF lifecycle (instantiation, scaling, termination). Option B is correct because the NFVO coordinates resources across VNFs and the infrastructure. Option C is incorrect because the VIM manages the NFVI, not VNFs. Option D is incorrect because the VIM does not handle service chaining; that is the role of the NFVO. Option E is incorrect because the VNFM does not manage physical hardware.

Answer

The Virtualized Infrastructure Manager (VIM) manages the lifecycle of VNFs and their connectivity.

Answer

The VIM is responsible for service chaining and policy enforcement within the NFV environment.

Answer

The VNFM is responsible for managing the physical hardware resources in the NFVI.

Question 10

Which two statements about native VLANs on an 802.1Q trunk are true? (Choose two.)

Accepted Answer

Frames belonging to the native VLAN are transmitted untagged on the trunk link.. The native VLAN is a key concept in 802.1Q trunking. Frames on the native VLAN are sent untagged to maintain compatibility with legacy devices that do not understand VLAN tags. Both ends of the trunk must agree on the native VLAN; a mismatch can cause connectivity issues or VLAN hopping. The default native VLAN is VLAN 1.

Answer

The native VLAN can be any VLAN from 1 to 4094.

Answer

The native VLAN is always VLAN 1 and cannot be changed.

Answer

A native VLAN mismatch will cause all traffic on the trunk to be dropped.

Question 11

Drag and drop each container technology on the left to its matching orchestration tool on the right.

Accepted Answer

Docker: Kubernetes. Docker is orchestrated by Docker Swarm or Kubernetes, but Kubernetes is the primary orchestrator; LXC/LXD is orchestrated by LXD; containerd is often used with Kubernetes; rkt was orchestrated by Kubernetes; and OpenVZ is managed by Proxmox VE.

Question 12

Drag and drop the steps of Q-in-Q (802.1ad) double-tagging configuration into the correct order, from first to last.

Accepted Answer

Enable dot1q tunneling globally. First enable the dot1q tunnel globally, then configure the access VLAN on the interface, enable the tunnel mode, and set the native VLAN to avoid conflicts.

Question 13

Drag and drop each route-target action on the left to its matching behavior on the right.

Accepted Answer

Import RT: Adds routes with a matching Route Target into the VRF. Import RT adds routes with matching RT into the VRF; export RT tags routes from the VRF; import map filters routes during import; export map filters routes during export; both import and export can be configured per VRF.

Question 14

Drag and drop the steps of EIGRP stub configuration for hub-and-spoke into the correct order, from first to last.

Accepted Answer

Enter EIGRP router configuration mode. In hub-and-spoke EIGRP, the spoke router is configured as a stub to limit query propagation. First, enter router configuration mode, then enable EIGRP on the spoke, configure it as a stub, optionally restrict advertised routes, and finally verify the stub status.

Question 15

Drag and drop each VLAN range on the left to its matching type on the right.

Accepted Answer

1–1005: Normal range VLANs. VLANs 1–1005 are normal range, 1006–4094 extended, 0 and 4095 reserved, 1002–1005 are default token ring/FDDI VLANs, and 1 is the default Ethernet VLAN.
