Answer

802.11g: 2.4 GHz, 11 Mbps

Question 2

Match each Cisco IOS command to its function.

Accepted Answer

show ip route: Displays the IP routing table. The correct matches are: show ip route displays the routing table, show ip interface brief summarizes interface status, ping tests connectivity, and traceroute traces the path. Common confusions arise from swapping the functions of show ip route and ping.

Answer

show ip route: Tests network connectivity

Answer

ping: Displays the IP routing table

Question 3

Match each First Hop Redundancy Protocol (FHRP) to its description.

Accepted Answer

HSRP: A Cisco-proprietary FHRP that uses an active/standby model with a virtual IP and MAC address, disabled preemption by default.. FHRPs provide default gateway redundancy. HSRP is Cisco proprietary, active/standby, preemption disabled by default. VRRP is open standard, preemption enabled. GLBP allows load balancing among multiple routers.

Answer

HSRP: An open standard FHRP that uses a virtual IP and MAC, preemption enabled.

Answer

VRRP: A Cisco-proprietary FHRP that uses active/standby model.

Answer

GLBP: An FHRP that uses active/standby model with no load balancing.

Question 4

Drag and drop each IP SLA operation type on the left to its measured metric on the right.

Accepted Answer

ICMP echo: Round-trip time. ICMP echo measures round-trip time; UDP jitter measures delay, jitter, and packet loss; TCP connect measures connection setup time; HTTP measures page load time; DNS measures resolution time.

Question 5

Drag and drop the steps of configuring LLQ (Low Latency Queuing) on a Cisco router into the correct order, from first to last.

Accepted Answer

Create class-map for real-time traffic. The correct order for configuring LLQ (Low Latency Queuing) on a Cisco router is: first, create a class-map to define the traffic class for real-time traffic (A). Next, configure the priority command in a policy-map to assign priority queuing to that class (B). Then, set bandwidth and queue-limit parameters for the priority queue within the policy-map (C). After the policy-map is complete, apply it to the interface using the service-policy output command (D). Finally, verify the priority queue operation using show policy-map (E). This sequence ensures proper classification, queuing, and activation.

Question 6

Which two statements about virtual machine migration (vMotion and cold migration) are true? (Choose two.)

Accepted Answer

Cold migration requires the virtual machine to be powered off before it can be moved to a different host.. Cold migration requires the virtual machine to be powered off before moving to a different host (B is correct). Storage vMotion migrates disk files between datastores while the VM remains running (C is correct). vMotion does not always require shared storage; modern implementations allow migration without it (D is incorrect). vMotion has minimal downtime but not zero, so A is false. Cold migration can move VMs across datacenters within the same vCenter, so E is false.

Answer

vMotion migrates a running virtual machine from one host to another with no downtime.

Answer

vMotion requires that both source and destination hosts share the same physical storage.

Answer

Cold migration can only be performed within the same vCenter Server and cannot move VMs to a different datacenter.

Question 7

Drag and drop the steps of RESTCONF GET with depth and field query parameters into the correct order, from first to last.

Accepted Answer

Construct the base RESTCONF URI for the resource. The process starts with constructing the URI, then appending depth and field parameters, sending the GET request, the server filtering the response, and finally the client parsing the returned data.

Question 8

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

Accepted Answer

Successor: Next-hop router with the lowest metric for a destination. Successor is the next-hop router with the lowest metric; Feasible Successor is a backup that meets the feasibility condition; Neighbor is a directly connected EIGRP router.

Question 9

Drag and drop the steps of troubleshooting an IP SLA operation into the correct order, from first to last.

Accepted Answer

Check IP SLA configuration. Start by checking reachability to the target IP (D) to ensure the destination is reachable. Then review system logs (E) for any errors related to IP SLA. Next, check the IP SLA configuration (A) for correctness. After that, examine IP SLA statistics (C) for failures or timeouts. Finally, verify the operation is scheduled and active (B) to confirm it is running as expected.

Question 10

Drag and drop the steps of Hierarchical QoS (H-QoS) parent/child policy steps into the correct order, from first to last.

Accepted Answer

Create the child policy-map with class queues. In Hierarchical QoS (H-QoS), the first step is to define class-maps for traffic classification (B). Then create the child policy-map that defines per-class queuing (A). Next, create the parent policy-map that applies shaping and references the child policy (C). Apply the parent service-policy to the interface (D). Finally, verify the hierarchical policy using show policy-map (E).

Question 11

Drag and drop each IP SLA tracking object on the left to its application on the right.

Accepted Answer

track ip sla reachability: Used with a floating static route. IP SLA tracking uses only two standard object types: 'track ip sla state' and 'track ip sla reachability'. 'track ip sla delay' and 'track ip sla threshold' are not valid tracking objects. P1, P2, and P3 correctly map to their applications: reachability for floating static routes, state for adjusting HSRP priority, and reachability for policy-based routing. P4 and P5 are incorrect because the specified tracking objects do not exist.

Answer

track ip sla 1 delay: Used to debounce state changes

Answer

track ip sla 1 threshold: Used to trigger event-based actions

Question 12

Which three statements about DHCP snooping are true? (Choose three.)

Accepted Answer

DHCP snooping is configured on a per-VLAN basis.. DHCP snooping is a security feature that filters untrusted DHCP messages. It builds a DHCP snooping binding database from trusted sources. Option A is correct because DHCP snooping is typically enabled on VLANs, not globally on the switch. Option C is correct because the binding database contains the client MAC address, IP address, lease time, VLAN, and port. Option D is correct because ports connected to DHCP servers are configured as trusted to allow DHCP server messages. Option B is incorrect because DHCP snooping does not prevent all ARP spoofing; that is the role of Dynamic ARP Inspection (DAI). Option E is incorrect because DHCP snooping does not encrypt DHCP traffic; it only filters messages based on trust.

Answer

DHCP snooping prevents all types of ARP spoofing attacks.

Answer

DHCP snooping encrypts all DHCP traffic between the client and server.

Question 13

Which two statements about multicast RP (Rendezvous Point) are true? (Choose two.)

Accepted Answer

The RP is used only in PIM sparse mode and is the root of the shared distribution tree.. The RP (Rendezvous Point) is used only in PIM sparse mode and serves as the root of the shared distribution tree. A single RP can serve multiple multicast groups, and multiple RPs can be configured for different group ranges using mechanisms like Auto-RP or BSR. The RP does not have to be the first-hop router for the source; sources can be anywhere in the network. The RP does not need to be directly connected to receivers; it only requires IP reachability. PIM dense mode does not use an RP at all.

Answer

The RP must be the first-hop router for all multicast sources in the network.

Answer

The RP must be directly connected to all multicast receivers.

Answer

In PIM dense mode, the RP is used to limit multicast flooding.

Question 14

Drag and drop the steps of OSPF summarization at ABR configuration steps into the correct order, from first to last.

Accepted Answer

Identify contiguous subnets to summarize. Summarization on an ABR uses the area range command to aggregate prefixes. The order is: identify prefixes, configure range, verify, and optionally suppress more specific routes.

Question 15

Drag and drop each trunk encapsulation type on the left to its matching standard or characteristic on the right.

Accepted Answer

802.1Q: Open standard (IEEE); inserts 4-byte tag; supports native VLAN. 802.1Q is an open standard that inserts a 4-byte tag, supports native VLAN, and is the default on modern switches. ISL is Cisco proprietary, encapsulates the entire frame, and does not support native VLAN.
