SSH Secure Remote Access Configuration and Verification
15 questions
A security review on an enterprise switch named Core-SW1 reveals that virtual terminal sessions allow plain-text remote management and bypass local account verification. To harden management access on Core-SW1, which TWO commands must be configured specifically under line VTY configuration mode (config-line) to enforce local account credentials and restrict incoming traffic exclusively to SSH?

A network technician needs to verify the configured SSH version, authentication timeout, and maximum retry limits on a Cisco IOS switch named SW-Access-01. Which privileged EXEC mode command provides this specific operational summary?
A network administrator is hardening remote management access on a gateway router named WAN-Edge01. The router already has a non-default hostname, a domain name configured (enterprise.net), and a 2048-bit RSA key generated. Security standards mandate that SSH Version 1 connections must be explicitly disabled and incoming VTY sessions must authenticate using the local router user database.
Which combination of commands satisfies these operational requirements?
A network administrator is deploying SSHv2 on a newly installed Cisco IOS branch gateway router named BR-GW01. Place the required CLI configuration tasks in the correct logical execution sequence from initial global configuration mode to final line security binding.

An administrator on a campus core switch named Core-SW1 is configuring SSH for secure management access. The administrator sets a hostname of Core-SW1 and attempts to run the command `crypto key generate rsa`, but receives the system message: `% Please define a domain-name first.` Which configuration command must be entered in global configuration mode to resolve this issue and allow key generation?
A network administrator is configuring secure management access on a newly deployed access switch named SW-ACCESS-03. The switch already has a non-default hostname and an active IP domain name configured. The organization requires that all remote administrative sessions use SSH version 2 and that legacy Telnet connections are explicitly blocked. Which two CLI configuration steps are required to complete this task? (Select TWO.)

A network engineer is inspecting the CLI configuration of a Layer 3 switch named Site-Core-01 to ensure secure administrative access. The switch currently has a valid hostname, a configured IP domain name, and active local user accounts. The line vty configuration displays the following output:
text
Site-Core-01# show running-config | section line vty
line vty 0 15
transport input telnet
login local
Which command executed within line configuration mode will restrict remote management sessions exclusively to SSH while enforcing authentication against the local user database?
A network administrator is hardening remote management access on a factory-reset Cisco IOS router currently running default factory settings. In what sequential order must the administrator execute the CLI commands to properly configure SSHv2 access using local user authentication?

A network engineer is troubleshooting secure remote management access on an enterprise router named EDGE-RTR-01. The router is currently permitting remote sessions, but output verification shows that SSH version 1.5 is active instead of SSH version 2.
The engineer gathers the following CLI output from EDGE-RTR-01:
text
EDGE-RTR-01# show ip ssh
SSH Enabled - version 1.5
Authentication timeout: 120 secs; Authentication retries: 3
EDGE-RTR-01# show running-config | include crypto key
crypto key generate rsa modulus 512
Which configuration change must be performed on EDGE-RTR-01 to support and enforce SSH version 2?
A network administrator is configuring SSH version 2 on a freshly unpacked Cisco IOS router. Which TWO configuration steps are required before the router will allow the generation of RSA host keys using the 'crypto key generate rsa' command? (Choose two.)

A network administrator is troubleshooting remote access on a branch gateway router (Branch-GW). SSH version 2 has been configured, but remote management attempts over SSH fail immediately with a transport layer connection error, whereas Telnet connections are unexpectedly accepted. The administrator collects the following configuration and status outputs from the router:
text
Branch-GW# show ip ssh
SSH Enabled - version 2.0
Authentication timeout: 60 secs; Authentication retries: 3
Device Mode: SSH Server
RSA Key size: 2048 bits
Branch-GW# show running-config | section line vty
line vty 0 4
access-class MGMT-ACCESS in
login local
transport input telnet
line vty 5 15
access-class MGMT-ACCESS in
login local
transport input telnet
Which configuration change must be applied to Branch-GW to resolve the connection issue and enforce secure SSH access on all VTY lines?
A network administrator is performing an initial configuration of SSH version 2 on a new branch router (Branch-R1). Place the required configuration steps in the correct sequential order from first to last.

An engineer is configuring secure remote management on a central router named Edge-Rtr1. The device has a valid hostname, an IP domain name configured, a 1024-bit RSA key pair generated, and a local administrator user defined in global configuration mode. The virtual terminal lines are configured with transport input ssh. However, when connecting via SSH from a remote client, the router prompts only for a password instead of requesting a username, causing all login attempts to fail. Which configuration change on Edge-Rtr1 resolves this issue?
A network administrator is verifying SSH remote access on a newly deployed enterprise switch named Dist-SW2. The hostname and IP domain name have been configured, and the administrator generated host keys using the CLI command `crypto key generate rsa modulus 512`. When administrative users attempt to establish remote sessions using SSH version 2, the connections fail. When the administrator executes the `show ip ssh` command on Dist-SW2 to inspect the SSH operational state, which status line is displayed in the output?
A network administrator is deploying SSH version 2 for secure management on a Layer 3 switch named HQ-AggSwitch01. The switch already has a non-default hostname configured and local user accounts created. Which TWO configuration steps must be completed to successfully enable SSH version 2 and restrict remote management access strictly to SSH on the virtual terminal lines? (Select TWO.)
