Question # 16

The ACL is placed on the inbound Gigabit 0/1 interface of the router. Host

192.168.10.10cannot SSH to host 192.168.100.10 even though the flow is permitted. Which action

resolves the issue without opening full access to this router?

Options:

Move the SSH entry to the beginning of the ACL

Temporarily move the permit ip any any line to the beginning of the ACL to see if the flow works

Temporarily remove the ACL from the interface to see if the flow works

Run the show access-list FILTER command to view if the SSH entry has any hit statistic associated with it

Exhibit:

Question # 21

An engineer configured R2 and R5 as route reflectors and noticed that not all routes are sent to R1 to advertise to the eBGP peers. Which iBGP routers must be configured as route reflectors to advertise all routes to restore reachability across all networks?

Options:

R1 and R4

R1 and R5

R4 and R5

R2 and R5

Expert Solution

Questions # 22:

Refer to Exhibit.

Question # 22

A network administrator added one router in the Cisco DNA Center and checked its discovery and health from the Network Health Dashboard. The network administrator observed that the router is still showing up as unmonitored. What must be configured on the router to mount it in the Cisco DNA Center?

Options:

Configure router with NetFlow data

Configure router with the telemetry data

Configure router with routing to reach Cisco DNA Center

Configure router with SNMPv2c or SNMPv3 traps

Expert Solution

Questions # 23:

What are two MPLS label characteristics? (Choose two.)

Options:

The label edge router swaps labels on the received packets.

Labels are imposed in packets after the Layer 3 header.

LDP uses TCP for reliable delivery of information.

An MPLS label is a short identifier that identifies a forwarding equivalence class.

A maximum of two labels can be imposed on an MPLS packet.

Expert Solution

Questions # 24:

Refer to the exhibit.

Question # 24

BGP and EIGRP are mutually redistributed on R3, and EIGRP and OSPF are mutually redistributed on R1. Users report packet loss and interruption of service to applications hosted onthe 10.1.1.0724 prefix. An engineer tested the link from R3 to R4 with no packet loss present but has noticed frequent routing changes on R3 when running the debug ip route command. Which action stabilizes the service?

Options:

Tag the 10.1.1.0/24 prefix and deny the prefix from being redistributed into OSPF on R1.

Repeat the test from R4 using ICMP ping on the local 10.1.1.0/24 prefix, and fix any Layer 2 errors on the host or switch side of the subnet. ^ C. Place an OSPF distribute-list outbound on R3 to block the 10.1.10/24 prefix from being advertised back to R3.

Reduce frequent OSPF SPF calculations on R3 that cause a high CPU and packet loss on traffic traversing R3.

Questions # 27:

Refer to the exhibit.

Question # 27

A network administrator configured mutual redistribution on R1 and R2 routers, which caused instability in the network. Which action resolves the issue?

Options:

Set a tag in the route map when redistributing EIGRP into OSPF on R1. and match the same tag on R2 to allow when redistributing OSPF into EIGRP.

Apply a prefix list of EIGRP network routes in OSPF domain on R1 to propagate back into the EIGRP routing domain.

Set a tag in the route map when redistributing EIGRP into OSPF on R1, and match the same tag on R2 to deny when redistributing OSPF into EIGRP.

Advertise summary routes of EIGRP to OSPF and deny specific EIGRP routes when redistributing into OSPF.
