Accepted Answer

Phase 1: Hub-and-spoke with NHRP registration. DMVPN has only three phases. Phase 1 uses NHRP for hub registration only; Phase 2 uses NHRP for spoke-to-spoke dynamic tunnel creation via resolution request/reply; Phase 3 uses NHRP with prefix-based spoke-to-spoke shortcut.

Answer

Phase 4: NHRP with BGP for routing

Answer

Phase 5: NHRP with OSPF for routing

Question 6

Drag and drop each IP SLA schedule parameter on the left to its function on the right.

Accepted Answer

start-time: Defines when the operation begins. Start-time defines when the operation begins; frequency sets the interval between probes; life sets the total duration of the operation.

Question 7

Drag and drop each broadband type on the left to its matching technology on the right.

Accepted Answer

DSL: Uses telephone line with ADSL or VDSL. DSL uses telephone lines with frequencies above voice. Cable uses coaxial cable with DOCSIS. Fiber uses optical fiber with GPON or active Ethernet. 4G LTE uses cellular radio. Satellite uses geostationary or LEO satellites.

Question 8

Drag and drop each CoS value on the left to its matching traffic type on the right.

Accepted Answer

CoS 5: Voice payload. CoS values are used in 802.1Q frames: CoS 5 for voice, CoS 4 for video, CoS 3 for call signaling, CoS 2 for critical data, CoS 0 for best-effort data.

Question 9

Drag and drop each HTTP method on the left to its matching REST operation on the right.

Accepted Answer

GET: Retrieve a resource. GET retrieves; POST creates; PUT replaces; DELETE removes; PATCH partially updates.

Question 10

Drag and drop each TACACS+ packet type on the left to its matching function on the right.

Accepted Answer

START: Initiates an authentication session and contains the username. START begins authentication and contains username; REPLY sends challenge or result; CONTINUE sends response to challenge; ACCEPT indicates successful authentication; REJECT indicates authentication failure.

Question 11

Drag and drop each SD-Access fabric role on the left to its matching function on the right.

Accepted Answer

Fabric Border Node: Connects the SD-Access fabric to external Layer 2 or Layer 3 networks. The fabric border node connects the fabric to external networks, the fabric edge node connects endpoints to the fabric, and the fabric control node manages LISP mapping and VXLAN tunnels.

Question 12

Drag and drop each DNA Center Intent API on the left to its matching use on the right.

Accepted Answer

inventory: Retrieves network device details, serial numbers, and software versions. Intent APIs: inventory retrieves device details; topology provides network maps; issues reports network problems; events tracks changes and alerts.

Question 13

Drag and drop each QoS model on the left to its matching characteristic on the right.

Accepted Answer

IntServ: Uses RSVP to signal per-flow reservations. IntServ uses RSVP for per-flow signaling, DiffServ uses DSCP marking for per-hop behavior, Best Effort provides no guarantees, IntServ requires state in routers, and DiffServ scales well for large networks.

Question 14

Drag and drop each STP timer on the left to its matching default value on the right.

Accepted Answer

Hello timer: 2 seconds. Hello timer defaults to 2 seconds; Forward delay defaults to 15 seconds; Max age defaults to 20 seconds.

Question 15

Drag and drop each EIGRP router role on the left to its matching definition on the right.

Accepted Answer

Successor: Next-hop router for the best route to a destination. In EIGRP, successors are the next-hop routers for the best path to a destination. Feasible successors serve as backup next-hop routers that meet the feasibility condition. Neighbors are directly connected EIGRP routers that exchange Hello packets. Feasible Distance is the lowest metric from the local router to a destination. Reported Distance is the metric that a neighbor advertises for a specific route.

Question 16

Drag and drop each VM network mode on the left to its matching behavior description on the right.

Accepted Answer

Bridged: VM appears as a separate device on the physical network. Bridged mode connects the VM to the physical network as if it were a separate host. NAT mode allows the VM to share the host’s IP address for outbound access. Host-only mode creates an isolated network between the host and VMs. Internal mode isolates VMs from the host. Custom mode allows the user to select a specific virtual switch.

Question 17

Drag and drop each BGP attribute on the left to its matching attribute type on the right.

Accepted Answer

AS_PATH: Well-known mandatory. AS_PATH is well-known mandatory; LOCAL_PREF is well-known discretionary; COMMUNITY is optional transitive; MULTI_EXIT_DISC is optional non-transitive; ORIGIN is well-known mandatory.

Question 18

Drag and drop each BGP attribute on the left to the value that is preferred (highest or lowest) during path selection on the right.

Accepted Answer

Weight: Highest. Higher weight is preferred; higher LOCAL_PREF is preferred; shorter AS_PATH length is preferred; lower MULTI_EXIT_DISC is preferred; lower IGP metric to next-hop is preferred.

Question 19

Drag and drop each BGP path selection criterion on the left to its correct order of preference (1 = highest priority) on the right.

Accepted Answer

Weight: 1. Weight (highest) is checked first, then LOCAL_PREF (highest), then locally originated routes, then AS_PATH length (shortest), then ORIGIN (IGP > EGP > incomplete).

Question 20
